Method and device for integrating wireless communication in private and public network environment

The present invention provides a method and device for performing wireless telephone communication operations in a private network environment and a public network environment. More specifically, the present invention is related to some communication systems, which can connect some wireless networks with some private networks, and these private networks are usually connected to public networks such as PSTN, ISDN and A network of various legal entities connected to the Internet, etc.

Traditional cellular system:

Todays various cellular mobile phone systems can support a large number and increasing number of h reds, each other, and BB._.Jiu Kuo emRbkh New Zealand is an aunt among the many pupal communication cells. "Huang Zhenjia uses the same system to provide wireless two-way frequency radio rRF1 to the public. Each individual cell covers a small geographic area, and many neighbors The cells of the cell can collectively cover a large gardens geographical mats. Shinichi Seosuke can use the available radio to talk about Zhongtu I. I. Part of the frequency band supports the communication needs of cell unit users. All cell units have different sizes. (For example: giant communication cells or small communication cells), and the communication capacity is usually fixed. The shape and size of various communication cells is a complex function of topography, man-made environment, communication quality, and communication capacity with users. Each communication The cells are connected to each other through the ground wire or microwave link, and the public lightning communication system network connected to rPsTN1, and the pupa vortex drops the telephone conversion devices used for mobile lightning injection pupa communication. Each of the conversion devices is used as a mobile phone user in each cell. When moving between regions, it can provide cell-to-cell and frequency-to-frequency transfer functions.

In the traditional cellular communication system, each cell has a base station: its radio frequency transmitter and radio frequency receiver are set at the same place to transmit and receive communication signals between cell users in the cell area. The year before the base station was used_LEffect_-Patrol) launch forward communication signal to users^'And use the reverse radio frequency or wave to receive the reverse channel communication signal sent by the user in the cell area.

sequence_oneBao He babbles and squints the message'so' it can be transmitted in two directions at the same time without interfering with each other. This kind of operation is called frequency-division arguing. In time division duplex (TDD) signal processing operations, the forward and reverse channels use the same frequency band to operate alternately.

In addition to providing radio frequency connection functions to users, the base station also provides radio frequency connection services to a mobile service switching center (MSC). In a standard cellular communication system, more than one MSC may be used in the entire communication coverage area. Each MSC can provide services for many base stations and related cell communication units in the system, and transmit call signals between other systems (such as PSTN) and the cell system or transmit calls between users in the cell system The purpose of the signal is to provide support for exchange operations.

Noisy, each base station is controlled by the MSC to patrol the BSC_I) Control its operation. The function of BSC is to allocate radio frequency or wave to support call operation, coordinate the handover operation of mobile phone user service support area between base station and base station, and monitor and report the status information of each base station. The number of base stations that each MSC can control depends on the communication volume of each base station, the cost of interconnection between the MSC and each base station, the topography of the service area, and other similar factors.

When a mobile phone user moves from the first cell area to the adjacent second cell^'Ren_mGbE spit_-wA product/m and u4±four t cut B one side.

For the convenience of description, the content of the present invention is described based on the GSM system, but readers should know that the present invention can also be universally applied to the communication system format of any wireless communication system.

GSM cellular communication system

Regarding the structure of the GSM system, in the book "Global Mobile Communication Bao I" published by M. Mouly and M.-B, Patetl992, as well as M, MoulV and M.-B.Pa_uTet has a detailed explanation in the paper "GSM Protocol Structure: Signal Transmission Method of Radio Subsystem" published at the 41st IEEE "Communication Technology Symposium for Vehicles" in 1992. The following sections specifically introduce some of the unique features of the GSM system.

The research and development of the GSM system started in J982 and was promoted by a research group named "GroupeSpeCial Mobile" established by the European Conference on Posts and Telegraphs (CEPT). The purpose of the teams research is to provide a 900 terabyte surname Niu film/Bu ιm, which can be used to unify the different analogue operating standards used throughout Europe. One k twenty one_oIn 1o2O., this research and development task was promoted by the "European Telecommunications Standards Institute" (ETSI), and the first phase of the GSM proposal was published in 1990. At that time, the United Kingdom (United National, UR) proposed a new GSM specification, which was exclusively for use at 1RGH from the north to the north₇Used by Dixun's Dixun system. The specification of this system was published in 1991 and was named "Digital Cellular Communication System" (DCS1800). The GSM network began operation in various European countries in the middle of 1999.

The specifications of the GSM system adopt many advanced service items and features, including: ISDN compatibility based on Q:93l, global roaming and other GSM network intercommunication services. Two-way messaging, data service, fax service, ISDN auxiliary service, but Yu, including the purpose of the GSM system, is basically used for health 64Lh_noThe curse of the sword / Yougui m / The pottery "I series aunt_.

GSM system structure

Standard GSM network sentence_/It includes three components, namely mobile station rMS), base station sub-system (BSS), and route sub-system (NSS). The GSM specification specifies various network entities and related interface facilities of each entity in the Public Land Mobile Communications Network (PLMN). The complete specification also includes some other documents, which clearly define the type approval procedure for each mobile station, so that each mobile station can be used in different countries, and is not limited to the type approved for use.^'Restrictions on use within the country.

Base station sub-system rBSS1

The base station sub-system (BSS) is composed of two main parts, namely: the base transceiver station (BTS) and the base station controller (BSC). The BTS includes a radio transceiver that sets the boundaries of the radio cell communication area, and it is responsible for the radio (Um) interface communication protocol between the processing and the mobile station. There are many different types of communication cell areas. Such as: large area (M2) type, small area type (micrO) and ultra small area type (pico), etc., which can be selected according to the requirements of terrain, telephone user density and communication coverage area. Among them, the large area (macro) cell area can be used for large communication cell areas with a communication distance from 2 kilometers to 70 kilometers, and a small area (miCr0.) cell area can be used for communication distances from 100 m to 5 kilometers. The use of the small communication cell area: to serve the masses of users in the way of fill or inreas. The purpose of the pico cell area is to support the needs of the communication cell area with a communication distance from 50 meters to 1 km, and can be used to improve the quality of local radio communication coverage. BTS can support the channel coding required for the operation of radio interface devices, decoding and misinformation, such as the reef. The speech can be used as powerful RTs, and it can be executed by remote control at the BSC or MSC. If the remote control code is used for operation, the BTS still needs to control this function.

The base station controller (BSC) can manage the radio resources of more than one BTS in the Abis interface. The BSC also controls most of the characteristics of the radio network, including the allocation of radio time slots to a mobile station, the release of resources, the interpretation of measurement results, and the control of the handover of the radio interface. BSC completes the interface connection with NSS through the A-interface of MSC. .

Radio transmission

BTS is responsible for maintaining the radio link with the GSM mobile station Zhiwang. At present, the MSC system can support operations in three frequency bands of 900, 1800 and 1900 MHz. Each radio frequency or wave is divided into eight time slots using TDMA. Eight consecutive time slots constitute the data segment of TDMA.

There are two kinds of logic channels sent out via the radio interface device, one is Yupas surname ja Wuyouye, E is Zhezaoyang custom-made oily. Sending Jewuyye is to provide a two-way point-to-point transmission to a mobile station. link. Each full-rate data traffic channel (TCHlF) and each half-rate data traffic channel (TCHlH) are allocated at the same time as a low bit rate and low-speed associated control channel (SACCH). The latter is usually used to transport the various required for the handover decision operation. Item measurement data. There are eight data rate channels, also known as "Single Dedicated Control Channel" (SDCCH), whose main purpose is to transmit location update data. In addition, the existing data in any TCH time slot can be cleared for signal transmission. The cleared TCH is called a "Fast Associated Control Channel" (FACCH), which may be a full-rate TCH, or It may be a half-rate TCH.

Each shared channel can be used by mobile stations in idle mode in order to become dedicated mode, or by mobile stations in dedicated mode to monitor surrounding base stations and collect handover data of mobile stations. The aforementioned various shared channels include:-

Broadcast Control Phidao rBCCH1

Continuously broadcast information on the downlink circuit, including the base station identification code,^'Frequency allocation information, and frequency jump sequence. ^：

Removal and correcting oily yin FCCH Pan tender oily toe SCH1

The mobile station is synchronized with the time slot structure by setting the start time of a TDMA data segment.

Random Access Channel (RACH)

The Aloba channel used by the mobile station to request time slot ordering in and out of the network.

Paging Channel (PCH)

It is used to warn that the mobile station has a call signal input.

Access. Authorized Channel (AGCH)

After receiving the incoming and outgoing network request message from RACH, it is used to allocate an SDCCH to a mobile station for signal transmission (to obtain a dedicated channel.

The force GqM a is estimated by Zhan Meiya to perform digital encoding processing at a rate of 13 kshaw yuan per second r13khns1, which is the so-called full-speed language encoding. This coding rate is more efficient than the standard ISDN coding rate of 64kbps. In addition, the GSM system also provides a half-speed speech code operating at a rate of approximately 7kbps in order to double the capacity of the network.

This 13khns clans old location data stream is separated into a sending estimate of rms1260 per 20 milliseconds., K sending cylinder is now donated to the front of the house to send out the L signal, after the channel number is processed Increase the bit rate to 22.8kbps (or 456 bits per 20ms). These 456 bits are divided into eight 57-bit data segments. The result is an interleaved arrangement of eight consecutive time slot pulse trains to prevent burst transmission errors from occurring.

Shinichi Yuma Kaimaiwei from the right 15675/i merge,_！A 57-bit data segment and a 26-bit training sequence can be used for equalization processing. A data group force U577ms to send out the cable star, and the pure bite sub-island 270.8kb0s, and also benefited from the fact that Jiabo is tied to a penalty wave of 7nnKH7 by G and L by G and L by GMqR1. The bit training sequence (TSC) belongs to a known type and is used to compare with the received information type in order to perform a wave of channel pre-authorization._o, The h-phase oil smelting official knife occupies back-to-back analysis technology nw, o forward error control and equalization processing can enhance the ability of GSM radio signals to resist interference and multipath attenuation effects.

Network sub-system

A necessary component of the network sub-system is the mobile service switching center rMSC1. MSC can provide functions required for switching between a mobile phone user and a PSTN or ISDN fixed network line in each cell of the network. In addition, the MSC can also provide various functions required to track and maintain communication with a mobile phone user, including recording, authentication, location update, job handover in the MSC area, and transmission of call signals to a mobile user . In order to keep in touch with all users of the network, GSMPLMN uses many databases. The various main functions of the database are composed of two "location registers", that is, "Large Seat Ju Zhan Zuo Cry I^-rHf, R1, Zhi, "Foreign Official Position Song Temporary Device" rVLK) 0

The local location register (HLR) includes all data related to a network operator's user database. HLR is the main database of a network. HLR can store static and dynamic data related to users. Static data includes items such as international mobile phone user identification data, user MSISDN number j, and registered (registered) supplementary service items. The state data includes^'For example: the current location of the mobile phone user (indicated by the VLR code and MSCE, l64 code), and the forward code of the call, etc. When a mobile phone user logs in a VLR area, the HLR will download or save the required data into a VLR database, and it can also provide the necessary functions for terminating the mobile phone call signal.

``The foreign official Zhan Song cuts left to cry IrVT, the R1 system is stored by HI_/R under or represents the user data of all mobile stations currently located in the VLR area. The data stored in the VLR may include the information sent by the HLR in the local area and the HLR in the outer area. VLR is used to provide the function of recording two call signals, "mobile station initiated" and "mobile station terminated". The .VLR system is defined as an independent database in the GSM system, but in order to give full play to the performance of the system, in many practical applications, the functions of the MSC and VLR are combined, so that the MSC area and the VLR area can be effectively combined. The same function.

And the "Authentication Center" rAUC) is a secure visa database used to store various authentication keys (according to a key (ki)) ) Provide to HLR and later VLR^'To verify the validity of the user registration information of the mobile phone user. The calculation program (A3) used to perform user authentication is stored in the users "user identification module" card and "authentication center" (AUC), and only the call (inquiry) signal and result signal can be sent to the wireless Room interface device. The call (inquiry) signal is also used by another calculation program (A8) to generate A5 radio interface translation and correction, French clues, white m, moxibustion, and M Guqi. To be clear, nqM can be recorded and used for evaluation. A3 knows A8 and other straightforward procedures, but practical L is mostly set by the system operator_oE Yi Xing surnamed shop color "Ke Lao Tian 2_IIw cut the left cry IrFTR1, there is a list of various "International Mobile Equipment Identification Data" (IMEI) values. Therefore, this database can be used to control (prevent) theft, type unauthorized or improper use of defective mobile phone devices. When a mobile phone user registers with a network for online operations, he can obtain IMEI data and verify whether his identification data is valid with the relevant data stored in EIR. If the IMEI information is on the blacklist, you can take appropriate measures to prevent the user from using the network communication.

Operation and maintenance

Those associated with BSS and NSS equipment are the operation and maintenance center, OMC_-R and OMC_-S. OMC_-The R series provides operation and maintenance control of various functions of GSMBSS. OMC-R is used to perform the following functions: the type of each network cell, this function includes radio frequency, handover parameters, cell parameters and timer values.

Performance monitoring, this function enables OMC-R to receive statistical data on various operations of the BSS, such as the number of cell areas, the number of handover operations, etc.

For reporting of warnings, OMC-R is used to observe and process various warnings initiated by BSS.

Under the software, OMC-R provides and updates the software added or added to the BSS. -

NSS equipment system and OMC_-S is associated. OMC-S can provide various high-level functions similar to OMC-R. In addition, OMC-S can also be used to provide user data management functions for HL.F and .VLR. However, this feature is usually multi-line_：Provided by a dedicated management center, the management center can also handle server opening requirements and SIM data.

Tentative expansion_-Li Liangkui^'

The prerequisite for GSM design is that it must have the function to work with ISDN. Therefore, the services provided by GSM should be a subset of various standard ISDN service items, but when more ISDN services are within the scope of the GSM agreement During development, this characteristic quickly disappeared. The GSM system can provide a series of "basic" and "supplementary" services. The basic service items are divided into "Long-distance transmission service items 10" and "One-way channel service items" o

"Kengli Teleportation Home" includes^：Voice, the most basic service.

SMS, packet, is a two-way information transmission service.

Type 3 fax, this service can be connected to type 3 fax machines^'

Cellular broadcast, this service can broadcast messages to various mobile stations.

"Upper Nesting Service" includes_：Asynchronous data 300-14400bps, which can be stored with normal V series modulation demodulators^-Take operation.

Synchronize data at 300-l4400bpS, which can be accessed with CSPDNs.

PAD service matters.

Encapsulated service.

Supplementary service items are designed to strengthen the functions of basic service items. The stage 1 specification can only provide call forward and call blocking services. Phase 2 supplementary services include line identification service, charge notification, multi-line group communication, call waiting and call holding services. Stage 2 ten service items will include: call forwarding, call completion busy user (CCBS), and the best path function that is not related to the basic characteristics of the mobile phone network as much as possible. The other sub-layer is supplementary service items. Its function can manage the execution of various supplementary service items, and also enable various users to access and modify their service reservation information. The last sub-layer is the short message service layer, which is used to process the delivery (transmission) operation of the intermittent messages that occur and received by mobile phone users.

j Matters concerning the structure of the existing GSM system

Therefore, the existing GSM cell line does not meet or satisfy the needs of this type of market.

The standard cellular system uses expensive large switches, and its voice or data communication exchange rate is limited to 64kbps. In various networks currently installed in the world, this basic operating speed limit of 64kbps prevents customers of cellular systems from receiving more advanced services, such as video and high-quality voice signals.

Many of the current cellular systems use the Signaling SyStem No. 7 (SS#7) format for telephone communication between the mobile station and the mobile station. The signal transmission system using this format will also enable the user to fully utilize the highest performance of the cellular network.

The original blood pure dripping cylinder Shishi iIImR is also wormed,_-The company's number and other business entities on the right side of the right white road and other industrial and commercial entities also need to enable their employees to use radio communication devices to access various voice and data information during their roaming operations.

Therefore, each mobile station 4 that communicates through each private base station P-BTSS27 in each private network 14 can use each terminal 21 in the LANS 24 and each public network 8 to access data. In addition, each base station P in each private wireless network 14_-BTS_S27 The available higher data rate is higher than that of the public wireless network 15 BTS_SThe available data rate. The private network data rate specified in the specifications of the example of the present invention is as high as 384 kbps, while the data processing rate provided by a traditional public cellular network is only 64 kbps. Therefore, the data retrieval operation functions of various private networks 14 are better than those shown in Figure j. Shows the data capture function of the public wireless network l5.

The private wireless base station P-BTS27 shown in FIG. 2 directly connects each mobile station 4 to other facilities in each private network 14 through the router 23, so that each mobile station 4 can be connected from each LAN network 24 The terminal 21 sends and receives telephone call signals. In addition, the communication distance between the mobile stations 4 in the private wireless network 22 using the standard Internet protocol (IP) can also be passed through the public networks The Internet in Road 8 extends to any facilities that can be operated on the Internet, such as the private networks of different LANS and different companies located in different regions or different countries.

As shown in Figure 2, each private wireless e 2 is merged with each public network for internal support for telephone conversion. Therefore, the function of each private network 14 in the system shown in Figure 2 is controlled by the owner of the private network 14 to accommodate the new Increase user demand.

Each mobile station 4 in each private network 14 shown in FIG. 2 is a traditional wireless mobile phone that is widely used and unmodified in general traditional public wireless networks. Therefore, each mobile station 4 can be displayed in the figure. l Free movement between the public wireless network 15 shown in Figure 2 and each private wireless network 22 shown in Figure 2 without any restrictions. With this free movement function, each mobile station 4 only needs to use one phone user number. Communicate in public network and private network.

The structure of GSMBTS-Figure 3

In a GSM-type specific example of the present invention, the public wireless network 15 shown in FIG. 1 includes the traditional GSM base station software 31 shown in FIG. 3, including its components 3l-1 and 31-2'. Component₃1w₂On the map^l_oneThe private 2 communication protocol (Internet protocol) used in each private network 14 in FIG. 2 does not provide call control or connection support. Since then, software 3l and component 3l_-l and 31.2 require a communication protocol interface to facilitate the interoperation between the wireless communication protocol and the wired communication protocol. For ease of description, in Figure 2 the communication protocols w28-1...28-P are placed next to each private wireless network 14, and are described in detail below.

P_-Brief description of BTS structure-Figure 4

In the specific example shown in FIG. 4, the deployment status of each base station P-BTSS in each private wireless network 14 shown in FIG. 1 and FIG. 2 can be seen. In this specific example, each base station P_-BTS27 contains a necessary protocol stack^'It is used to perform various processing functions on the wireless control signals from the mobile station 4, the H.323 terminal, the gate holder 41 and the gate 42. In this specific example^'The H.323 destination may be a personal computer (PC) terminal 21 (see FIG. 2) and another mobile station 4. The gateway holder 41 provides the required functions to control various "terminals" in the H.323 field. In this specific example, the "terminals" include GSM-type mobile stations 4.

The necessary functions provided by H.323 and the gateway holder 41 include the data storage of the mobile station 4 (equivalent to the location update function), the control of the permission to access data to the network, and the interpretation of the call number when necessary And call signal transmission and other functions. Make this h69 people sweet ww network lame J5 MSCl7 or HTR1qr staff and lie 11 by the various functions that can be sent by Dang Dang. Each of the gate holders only needs to exist in any base station P-BTS27 in the H.323 field shown in Figure 4 (that is, P-BTS27-1, P-BTS27-2 and P-BTS27-3 in each base station In any base station). In the example shown in Figure 4, P-BTS27_-3 Provide the function of the gate circuit holder in the H.327 field, and support P-BTS27_-2 and P_-Operation of BTS27-1.

In order to support all wireless communication functions, the functions of the standard H.323 gateway holder must be expanded. This redesign includes the addition of a local user database (LUDB) 66 (see Figure 6) to control the mobile station and provide auxiliary service (SS) functions.

Any update or string change data that occurs due to the interaction of the mobile station 4 is included in the return to the intermediate protection device 41r, please refer to the main gate holder database 7-3 stored in FIG. 7). This method can reduce the amount of call control signal processing required in a LAN communication network area, and can also improve the reliability of the network system.

In order to provide interconnection with external PSTN or public wireless networks, an H.323 gateway holder 42 is provided in FIG. 4. The gateway holder 42 can provide line interface and conversion coding functions, so that voice and data communication information can be sent to various existing networks (for example: PSTN, ISDN)_'B-ISDN, PBX).

When a P_-When BTS27 is used in a LAN operating environment shown in Figure 4, another additional function required by the base station is when a mobile station 4 moves back and forth within the LAN area of the private network service shown in Figure 4 and Figure 2. During the period, how to control the operation handover function of these mobile stations 4 between different base stations P-BTS27. The handover decision is made inside each P-BTS27 base station. Only the signal needed to instruct a handover operation needs to be transmitted between the P-BTS27 base stations.

Network operation

This section lists several situations to illustrate how a P-BTS27 in a network uses the above-mentioned various modules as shown in Figure 4 to provide the same types of services as the various services usually provided by the traditional public cellular system with a general GSM structure. Some situations are representative examples for users who need cellular communication system services to refer to, and other similar practical system structures can be designed based on these operating frameworks.

In addition, it should be noted that the P-BTS that processes the call signal may also be robbing the bar character in the network domain._-RTq.

The following terms used in the following various situations are defined as follows: A private network refers to a spine composed of P-BTS operated by the various modules mentioned above. The user information of each mobile station is placed in the private network gate guard 414 (see Figure 4).

-A network pot refers to the private network (including all P in the network)_-The owner (owner) of the BTS unit (such as a company or other entity). It may also be that the private wireless network is managed by a public network operator under the supervision of the private network owner.

A private mobile terminal refers to a wireless network serviced by the private wireless network. According to the agreement between the public wireless network operator and the private network owner, the mobile station can also be permitted to operate within the service network domain of the public wireless network.

w. A Cobo terminal is a terminal with a fixed position on the LAN or attached PBX. The terminal may be an ordinary fixed PBX telephone, or a telephone attached to a desktop personal computer (PC).

A public network is a general public wireless communication network controlled by a licensed operator. The network contains a plurality of common cellular entities, such as: MSC, VLR or HLR.

'A public wireless station^'It is a narrow abundance. A wireless station to be located on the cellular public wireless network. According to the agreement (contract) between the public wireless network operation and the private network owner, the mobile wireless station can also be moved into the private wireless communication network domain. The user data of this mobile phone user is placed in the HLR of the public network operator.

A public network political and economic personnel should be the licensed owner of a public wireless network. The domain of the private wireless network with the relevant operating spectrum is also within the domain of the public wireless network.

In the examples described below, it is assumed that the mobile station 4 is a standard wireless station that does not need to be modified. In this case, the wireless station is a user^'The identity recognition module rSIMwm recognizes the identity of the user and contains a unique national mobile device identification code w).

In the following description, it is assumed that the "network" can perform number exhaustion and translation operations so that various call signals can reach the gateway 42 of the private network (see Figure 4) or the related public cellular network . This assumption means that the number of the wireless station is a unique and dedicated number in the national numbering system.

Mobile terminal login operation

The login operation must be handled in three different situations: the private terminal is registered in the private LAN area and there is no terminal to the public wireless network is registered in the public wireless network._LThere is a lack of registration in the LAN area. Within the scope of each situation, several variables have to be considered. In particular, among the important factors that will affect the operation of the private network, the one that should be considered most is the variable registration requirements that may be implemented on the private mobile station 4. In the following sections, we will discuss the alternative solutions for the various changes between the private network registration process and the general public cellular network registration process.

Private terminal login in private H.323 area

The procedure of the terminal registration phase of the private mobile station in the private LAN network is the same as the terminal registration procedure in a public wireless network. To accomplish this, P-BTS must broadcast the same kind of information that can be found on a "normal" public wireless network 15 on the Broadcast Control Channel (BCCH). When the terminal detects and broadcasts the information on the channel, it can perform the usual registration function shown in Figure 19. The login function will be terminated at the wireless gatekeeper database. Another alternative is that the wireless gatekeeper can also retrieve user data from a public HLR database for P-BTS use. ,

The signal transmission between P-BTS and P-BTSI gatekeeper functions uses standard H.323 registration request (RRQ) message processing sequence. If the RRQ operation sequence does not work, then I use a "position rejection" message to terminate the operation sequence with the mobile station_pimprison9 spells i as Chi) I: It is composed of the following multiple operation phases from Zhuangxi Mountain.

Stage 1: This stage is a general location update request made when the mobile station detects the private (local) network to which it belongs. In this case, the mobility management (MM) layer in the P-BTS will terminate the signal transmission of this message.

Waist section 2: Suga the MM technical makeup white I, the account of the song string and the reason,, (ι mesh starts to log in with the private wireless gatekeeper once. In order to perform this operation, use H.323lRAS The signal transmission method sends a registration request (RRQ) to the private wireless gatekeeper. The RRQ message packet will contain the IMSI, call signal, RAS, and H.245 transmission location for the P-BTS for the request to log in to the mobile station. And other information.

If the IMSI related to the private mobile station has completed the registration procedures with the P-BTS that provides services, there is no need to check with the gatekeeper. But in this example, it is expected that an "IMSI attach" is more useful than a "location update" request.

If the IMSI security option is used in the private domain, when the first login is performed, if the "Location Area Identification Code" (LAI) is not accepted for the "Location Update" request P_-For BTS authentication, IMSI must be retrieved first.

When the gatekeeper receives an RRO, it will check that the IMSI (or TMSI+LAI) that appears in the RRO. can be allowed to register on the private network. This function enables the operator of the private network to actually control the access (or in and out) operations of its network. It can also allow or disallow private or public network users to enter and exit the network. After checking the IMSI, the private wireless network gatekeeper can take some necessary measures according to the operating mode set by its system.

If the_IMS Shun Yu-Private.^'And if the user's information has been registered in the gatekeeper database, the gatekeeper will send a "Registration Confirmation" (RCF) message back to the P-BTS applying for registration. If the private mobile station has established an association with another address (for example, another P-BTS), the gatekeeper can perform a "cancel registration request" procedure to eliminate duplicate information. According to this, this H.323 stacking procedure is a unique design for implementing the present invention.

The IMSI belongs to a mobile station^'And when the user information of the mobile station user is not recorded in the gatekeeper, the gatekeeper requests another gatekeeper located in the private network to verify the user's data. At this time, the data must be transferred to the gatekeeper before the original gatekeeper can continue its inspection operation.

Make sure that the IMSI belongs to a public mobile station, or it belongs to a private mobile station that needs to use a public HLR, and the Pangyao Gatekeeper uses a modified private wireless communication gateway to obtain relevant information from the HLR of the public network. Library information. The gateway from a private network to a public network compiles its internal H.323 signal transmission method into a specific signal transmission method common to private wireless networks for public^'Use the HLR of the network to work with each other. At this time, the data is relayed to the P who provides the service_-BTS. However, the "location update" request may also be rejected by the public network HLR. If so, the private network must also reject the mobile station user's "location update" request.

If the HLR accepts the application, it must store the El64 number of the "gateway" to process the call signals between various mobile stations.

Phase 4: After completing the operation of the login phase, the data must be transferred from the private wireless network gatekeeper to the P-BTS. This data transfer action is the TFTP message shown in Figure 9, but Figure 9 is only an illustrative example. In practice, other techniques can be used depending on the amount of data to be transferred. If the number of data to be transferred is very small, these data can be attached to the RCF newsletter, packet, or alternative new information composed of H.323 format "non-standard message" can be used instead. The accuracy of the alternative new message format does not affect the results required by the present invention.

Stage 5: When the data is transferred to the P-BTS that provides the service, the registration procedure for the mobile station is completed.

Location registration procedure₁Figure 9_/

Figure 9 illustrates the operation flow of the private mobile station registration operation in the public GSMPLMN. As for the method that should be used to perform the registration operation of the private mobile station in the public network, it depends on the network structure type. Two alternatives will be described below. The prerequisite is that the private mobile station has been approved to log in to the public network._-.

Private network database:_lIf the users data is kept in a private network database on the private wireless network gatekeeper (as described above), when the private mobile station is registered in the public network , The MSC providing the service is bound to perform data access operations to this database through its gateway function. The private wireless network gatekeeper retains the MSC and/or VLR numbers for use in response to calls between mobile stations.

Public bundled data is average: if the estimated users data is to be retained in the HLR of the public network, the registration procedure is the same as that of a general GSM-type mobile phone system.

Public mobile stations and private H.323-style domains_-You can log in: When a public mobile station logs in in the LAN area, the private wireless gatekeeper will query the public network HLR where the public mobile station is located.

There are four types of mobile stations launched and called C) need to be considered. These calls are calls to the following four types of mobile stations: private mobile stations located in a private network domain or private mobile stations with a fixed terminal station in a public network domain. A public mobile station located in a private network domain. A public mobile or fixed terminal station located in a public network domain is a message sent by a mobile station (MOC), which is the most difficult message to determine the destination of the call and how to send it. The following sections explain in detail how to determine the method of sending a call message.

Rod button, hole cylinder, right tied anvil, i cylinder, right rod, vanadium, Wu Tongfang, final glass table, launched an up call

When any private mobile phone user executes a call initiated by the mobile station, its operating procedure should be "the same" as the commonly used call procedure in a common public wireless network. The call procedure is shown in Figure 10 and Figure ll. Show. The signal transmission between P-BTS and private wireless network gatekeeper function can adopt standard H.323 message operation sequence. Figure 10 and Figure 1n blink call J curling procedure includes the following stages: Stage 1: This stage is a general CM service request when a mobile station wishes to perform a call operation initiated by the mobile station. In this example, the mobility management (MM) layer in the P-BTS will terminate the signal transmission processing of this message.

Phase 2: For the general call operation established in this phase, the mobile station continues to send a SETUP message, including the phone number (CPN) of the party that will be called. The "connection management (CM) layer" is responsible for transmitting this call message to the network.

Stage 3: The CM layer uses the RAS permission application (ARQ) procedure to start the access procedure to the P-BTS/gatekeeper in the H.323 stack format. The purpose of this procedure is twofold: one is to find the location of the party on the receiving end,^-The second is to apply for the right to use the LAN bandwidth required for the call operation. In a small or independent network, ARQ procedures may be redundant." However, when the P-BTS is located in a negative or heavier network, it is easy to coexist with other P-BTS, and it can also be used to guard the gate. The qoS program is more commonly used in P-BTS. By P_I-. The ARq message generated by BTS contains CPN. The CPN number is used by the gatekeeper to determine the processing procedures that should be taken to establish the call operation. The exact processing procedure varies according to the special needs of the operator, and therefore, the present invention does not describe it.

The path information required by the H.323/q.931 SETUP message may be returned to the P-BTS that provides the service in the form of an ACF message or packet. If the information cannot be identified, or the party who initiated the call operation fails to pass other inspections, the call operation procedure may be rejected at this node and the call procedure will be terminated.

Phase 4: When the P-BT5 that provides the service receives the ACF message and packet, it can send the H.323 SETUP message and packet to the destination station. It should be noted that the destination station can be used to call forward or other forward operations. Once the CM layer receives the H,323 call procedure, it can continue to call the mobile station.

Stage 5: When the H.323 stack has received the H.323 call progress message, the audio channel can be established. This work is completed by the terminal function, master and slave, and two-way channel opening (B-Openchn) sequence operation procedures. Once the mobile station is assigned a radio wave, it can talk, thus avoiding any voice cutting problems.

Stage 6: The call operation is completed when a call progress message is sent to the mobile station. The mobile station will then be delivered to the communications service channel (TCH). Then use the warning and connection procedure to end the call establishment procedure.

When establishing this call operation, it was assumed that the receiver is a private mobile station or a private fixed terminal station in the same H.323 area. In this case, the terminal station function will arrange the processing procedure to be responsible for selecting the correct code.

Continuing l0 Fig. 11 is an explanatory diagram illustrating the operation flow of a call initiated by a mobile station to a private mobile station in a public network domain. If the call initiated by the mobile station is to call another private mobile station currently registered in the public domain, there are two alternative operating procedures depending on how the user data is stored in the network. If the user data is stored in the private wireless network gatekeeper, some location data needed to transmit the call signal will be sent back to the ACF, and the ACF should direct the call signal to the private The public MSClVLR of the mobile station. If the user data is stored in the HLR of the public cellular communication network, the gatekeeper must request the location information from the public network HLR, or directly send the proximity call signal to the nearest one at that time MSC processing. Therefore, the transmission service of the (location) data required for the call will be directly provided by the HLR or indirectly provided by the MSC. In the above various situations, the H.323 SETUP (established) message, the packet will be sent to the gateway unit and then sent to the external network. At this time, it is also necessary to use the code escape function of the printing unit.

Public mobile station located in a private network domain

If a bleating call initiated by a mobile station is to call a public mobile station that is currently registered in a private domain, it depends on the way the user's data is stored in the network, and there are two options for nesting program. If the user information is stored by the public wireless network gatekeeper, this indicator is used to interrupt (omit) the need to query the public HLR, and the address data required for the call is sent to the ACF For processing, the ACF directs the call signal to the P-BTS of the called public mobile station. At this time, the H.323SETUP message is directly sent to the P serving the public mobile station_-BTS.

If the user location data is stored in the HLR of the public network, the private network gatekeeper will request the location data from the public HLR. This task is to provide the transmission function of the data needed to establish a call operation via the H.323 gateway. In this case, the gate is responsible for determining the location of the public mobile platform. Therefore, in practice, the operation method described in the preceding paragraph is the best method in terms of signal transmission performance. Therefore, if the public mobile station cannot be found in the private network, the gatekeeper only needs to contact You can obtain the required position by querying the HLR of the public link_lAddress information.

Public mobile station or public fixed terminal station in public domain

If the call initiated by a mobile station is calling a public mobile station or a fixed terminal station in the switched telephone (CST) network domain, the call signal is sent to the gateway. However, in order to speed up the process of establishing a call, the private wireless network gatekeeper searches for the CPN data on the private network before sending the call signal to the gate. Then, the gate is responsible for signal transmission and providing necessary code-escape functions and other operations.

Different situations need to be refilled^-Che Ao poles use a pole-moving station to self-report. iZa pq: A private mobile station or a fixed terminal station located in a private network domain is a private mobile station or a fixed terminal station located in a private network domain. The mobile station is located in the public network domain public mobile station or fixed terminal station mobile terminal call (Mo address TerminatedCall, MTC) situation is the most direct call situation. In most of the above cases, the call flow is the same: the only difference is that the final point and signaling (Signalling) need to reach that point.

A private mobile station or fixed terminal station located in a private network domain calls private mobile A

This operation covers two situations, Chi Lang is a call initiated by a fixed computer terminal in H323 format granted by Oichi Wei, and a call initiated by another private mobile station. In both cases, once the call destination address of the private mobile station is determined, the transmission flow path of the call signal is exactly the same. The call operation process shown in Figure 12 includes the following operation stages: Stage 1: The call is made with the mobile station as the receiving terminal station._-The H.323 SETUP message sent from the q93l signal transmission location in the BTS starts after it arrives. Then, the CPN number in the SETUP message is used to view the forward paging (paging) information for the private mobile station. The H.323 call progress message is then sent back to the calling endpoint.

Stage Z: When there is a network that needs to be hijacked by a car in the autumn, the call operation will be done by clicking the button and filling in the final call.^-At this time, a normal paging (paging) request is made to the private mobile station. When the mobile station responds to the paging (paging) request, it can perform general authentication and encoding procedures. During this period, the RAS layer may need to start an ARQ procedure with the registered gatekeeper in order to reserve the required bandwidth. .

Stage 3: The GSM call side six program is bashed, and the mobile station will receive a signal transmission function (Bearer Capabiliti)._es) Of the SETUP message, this message, the package is the message needed to establish the call operation, so that the mobile station can correctly determine the type of call. For example: a MIC data call may need to activate the modem in the mobile station. When the mobile station sends out the call confirmation packet, the H.323 stack can continue the call operation of the LAN part.

.Phase 4: When the H.323 stack receives the Zhazhou tribes information from the pole-moving station, the H.245 layer should start to carry out the necessary terminal functions. ) And other operating procedures to establish an RTPIRICP transmission link between two terminal points.

Stage 5: Try to make a lead, visit Benju 4E_oK5 Twenty: The main report and the connection message are sent back to the call endpoint in the private network. After receiving the "connection" message, the CM layer can request the assignment of the required radio resources .

In the process of establishing this call operation, it was assumed that the called end is a private mobile station or a private fixed terminal station located in the same H.323 operating area. In this case, the terminal function arranges the processing operation. Select the correct code.

The call release procedure is noted as 13k ren.

When performing a fixed-terminal switched telephone (CST) operation on a private mobile phone on a private network, the call signal is first transmitted to the nearest H.323 switch through the PSTN1ISDN network (subject to local regulations) On the road...the .l gate road should then be consulted with its local private wireless gate guard, h_/It may be necessary to inquire other gatekeepers to search for the transmission information required by the temple. Once the returned information is received, a call connection with the called terminal station P-BTS can be established via the Internet .

Is the positional power comparable to that of the k male mH in the tie?

When a call is initiated from a public mobile station located in the private network, the first thing to do is to find the destination address of the called mobile station. At this time, the P-BTS that provides the service must query its registered private wireless network gatekeeper to determine the address data that needs to be sent. Once the location data that should be sent is determined, the call signal can be sent to the called terminal mobile station.

Then, the gateway should check with its local private wireless network gatekeeper, and may also need to check with other private wireless network gatekeepers to find the information that needs to be sent^'Once the transmission information is received, the call can be established with the T-BTS of the called end via the Internet.

With P_:BTS station handover and payment drawing l4)

Figure 14 shows a detailed illustration of a handover operation. There are several types of handover operations: handover within a private network-handover between private networks, private network to public network handover, public network to private network handover The first two handovers are because the handover procedures are very similar. , Which will be explained in the next section^'The latter two transfers will not be discussed in detail, because the required transfer procedures can be established by themselves in accordance with the first two methods.

Handover within the private network and the rice between private bundles

In order to provide continuous coverage function (in-network coverage) in the private network domain, at least it must be able to perform intra-network handover and network-to-network handover. In order to simplify network operations, P-BTS Perform calculation of handover candidate stations based on the measurement data sent by the mobile station. Once you have identified a candidate for handover and decided to perform the handover, you need to start the handover operation. There are several handover processing methods available. The easiest way is to use the H.323 format conference operation function and the resources provided by the gatekeeper l multiple conference unit (MCU) as the old P-BTS and target P- The bridge between BTS. The other method is to use the Internets multiple options_-The BTS and each target P-BTS transfer the upper chain and the lower chain IP data seal. In either case, the target P-BTS activates a new radio communication interface, prepares to accept the mobile station "call control" state machine, and establishes the necessary routes to and from the network. Once the new radio communication channel has been completed, the terminal The station is then instructed to move to the newly designated P-BTS station, and the old P-BTS station will be released at the same time._-All resources of BTS station. If each P-BTS uses a different LAI, the location update (login) operation can be automatically performed when the call is terminated. When the handover operation shown in Figure 14 is executed, the operation sequence of the following stages is as follows: "Stage l_：Once the handover operation has determined that the handover operation needs to be performed, one must immediately determine the transmission addresses of the newly designated base station. Newly selected, the base station address is determined by using the RAS address request procedure and using the BTSID as the called party. If appropriate, this operation can extend its general scope to include the location data of each BTS in the public GSM network.

pressed2^：The silicon gatekeeper knows the delivery address of the target BTS (EP3), and the address data is sent back in the LCF. At this time, the old BTS (EP1) must request resources from the target BTS. The resource request information is to add a new "non-standard message" to the H.323 command list. This new message is to obtain the necessary resources from the target BTS. This message also includes call control information related to the mobile station. In addition, to speed up the location update operation, the message can also be the user data of the old BTS.

If it is handed over to a public network, the "non-standard message" must be sent to the gateway and converted into a "handover" message format that conforms to the public network. And the gate must also begin to process the call signal for the old BTS.

Stage 3: Once the BTS receives the resource request, after the package, if there are available resources, it should answer the old BTS with a confirmation message, package and a multiple delivery address that can be used by the old BTS .

Phase 4: After the old BTS receives the confirmation message and the packet, it starts to establish a conference communication path between the destination BTS (EP2) or the fixed terminal station and the target BTS. When the establishment of the multi-projection distributed conference path is completed, the old BTS can instruct the mobile station to be handed over to the target BTS to take over.

stage. 5: The handover instruction is sent to the mobile station, and the mobile station starts to establish an access operation channel with the target BTS at the specified time slot. Once the mobile station has established a connection channel with the target BTS, it will send an "end procedure" message to the old BTS to release the communication resources originally obtained by the BTS. At this time, the control task of the call operation has been delivered to the target BTS.

In order to accommodate various handover situations, P-BTS uses the BTSID to determine whether to use synchronous or asynchronous handover operations.

Readers should be aware that this procedure can be applied to both private and public mobile platforms. The deduction procedure can also be used as a reference for operations when the public qSM network needs to be transferred in and out.

Mutual connection between VPN and GSMPLMN A imprison15

In Figure 15, there are several BTS27_-1,27_-2 and 27_-3^’The constituted P-BTS type virtual private network (VPN) 34 is connected to the GSMPLMN through the connection center 23 and the router 33 leading to the Internet 24. In Figure 15, the wireless network gatekeeper 4l^lIt is P_-BTS3_-27_-3^lPart of. The gatekeeper 41^lUse a simplified public wireless cellular signal transmission system to communicate with the public cell HLR19. Therefore, the Internet can be used to connect to the HLR 19 via a dedicated trunk line from a gateway. The trunk line connects the H.323 gateway to the^-The MSC is then connected to the HLR19. At HLR19, a translator IPSS7 is used to superimpose the control signal from the outside on the IP and send it back to SS7 after conversion. In order to effectively support the wandering communication of private and public mobile stations, it is best to install the above-mentioned IP to SS7 translation unit in the public cellular network HLR19. It can provide services to many private networks, such as Figure 15 In each network 14"-1 to l4-M, and private network l4-1. With this design, you can easily implement public-to-private and private-to-public roaming communications. Many manufacturers can provide IPlSS7 translator. This function can also be used to send short messages between private and public domains.

The handover support operation can be achieved by adding a handover support device in the gate and adding an IP-toSS7 converter to the nearest MSC. The design of this additional device helps to transfer the handover message, including the handover message to and from the MSC through the H.323 gateway, and then transfer the message to the P that provides the service._oneBTSo,
