How to transport simple text messages within a wireless telecommunications system Background of the invention Field of invention The present invention is generally in the field of telecommunications and, in particular, in wireless telecommunications systems. Short text messag es) Regarding transportation. History of related technology Global System for Mobil e Communications; GSM) is standard in some European countries This is a digital mobile cellular radiotelephone system that has been introduced in Japan. By GSM Basic telecommunications services maintained by both fixed and mobile subscribers Voice communication, CCITT Group 3 facsimile transmission, and 9.6 kbit / s Includes synchronous data transmission and asynchronous data transmission at speeds up to. For special telecommunications services maintained by GSM, simple text messages There is a service (Short Message Service; SMS). S MS, GSM to mobile stations and from now on through signal channels 160 alphanumeric characters each Allows routing for simple text messages up to length To. If the mobile station pointed to the simple text message is not in service, or If you have left the coverage area, the message is a brief sentence Short Message Servic e Center; SMS-C) is stored. SMS-C is served by mobile stations When returning to Su or re-entering the coverage area, this message will be transferred Transfer to the motive. SMS is a simple character message service terminal in the data network ( Short Message Service Terminal; SMT) It can also transfer simple text messages to and from GSM mobile stations. GSM is divided into exchange subsystems and base station subsystems. Is it a mobile station? These calls are received by the base transceiver station, which is the base station It is a part of the system. The base transceiver station is within the geographic service area Define individual cells. The base station controller in the base station subsystem is also the base station Controls a group (cell) of Lanceva stations. There are several base station controllers 1 Two mobile service switches Serviced by the ing center; MSC), the MSC is an exchange subsystem Form a part of the tem. MSC is a public telephone network (Public Switc) hed Telephon Network; PSTN), Comprehensive Service Day Digital Net (Integrated Services Digital Net) work; ISDN), Public Land Mobi le Network; PLMN), and various public and private data networks Control calls to and from other telephone and data communication services, such as .. If a user in another network (eg PSTN) calls a GSM subscriber , The call is connected to a gateway MSC (GMSC). GMSC is a replacement service Home location register (home), the database in the system By contacting the location register; HLR) , Find the location of GSM subscribers. HLR is currently the newest M for GSM subscribers Provide that address within the SC area. GSMC to call the MSC Select a route. The current location of GSM subscribers is the visitor location register ( In the visitor location register; VLR), Then, the current position is detected (located) in the MSC area. It is maintained in a database that contains information about all of them. If GSM subscribers If you roam into the new MSC area, the VLR associated with this new MSC is HL Request information about the subscriber from R. At the same time, HLR has subscribers resident Be informed about the new MSC to be. In GSM, simple text messages are sent by mobile origi. nated) or mobile incoming call (mobile) It may be terminated). Mobile outgoing simple text message (mob) ile originated short message) is a mobile terminal Submitted to the visited MSC via the base transceiver station To. The visited MSC sends the message to the originating mobile terminal (originating) Ship to SMS-C given by mobile terminal) .. SMS-C sends the message to its destination, which is moved within the data network. It may be a motive or a terminal. Mobile incoming simple character message (mobile terminated sh) ort message) is submitted directly to SMS-C by the user. S MS-C moves the message to the simple character message service gateway. Body service exchange center (short message service-gat) eway mobile switching center; SMS-GMS Ship to C). SMS-GMSC is related to transferring information HLR And reroute to the appropriate MSC for the message. Destination transfer The motive is paged and the connection is set up between the MSC and the mobile station. To. When set, the MSC sends the message to a signal channel (eg, self-contained). Ships to mobile stations via a dedicated control channel (SDCCH). if If the message is delivered successfully, the notification report will be sent from MSC to SMS-C Will be sent. If it was not delivered successfully, the HLR will be notified and And the failure report is sent from MSC to outgoing SMS-C. Notification report or failure report Can be sent by SMS-C to the message originator. For the user to receive and send the text in the simplified text message Fixed simple character message control data is given to SMS-C. This control The data is when and how the message sender (eg, 4 pm) and how (eg, 4 pm) Along with whether the text is to be sent to the destination (by fax) Allows you to specify the destination subscriber as SMS-C. In GSM, SMS is Q .931 Exclusive SMS protocol in parallel with message orientation call control protocol It is embodied by including. Q.931 Call control interface (also referred to as CCIT Recommendation I.451) Specifies what goes into the signal packet and also the message type and its contents The protocol to define. In detail, Q.931 call control interface , Call setting, call withdrawal, callee number information, caller number information, transmission function (eg, From anomalous events such as voice or data), (protocol failure or "busy" relay line It stipulates status inspection (for recovery of), release of transmission channels, and notification of errors. Q .931 Call control interface is CCITT No.1 digital subscriber signal Method (CCITT Digital Subscriber Signalin g System No.1; D: SS1) User-Network ISDN interface Derived from. For example, Personal Digita l Cellular; PDC) method (Japan Digital Cellular method, that is, , Also known as JDC) in other digital mobile radiotelephone schemes Q.931 The call control interface is specified to be used, but It doesn't have a parallel SMS interface. Therefore, the simple character Messe The page can be transported within these networks via the existing Q.931 interface. Although it can be done, simple character message control without a special SMS interface Problems arise in attempting to transport data. The traditional solution to this problem is Q. 931 User-User Information Element; UUIE) field for simple character message call control data To include. However, this solution raises other issues, the reason for which is UUIE. The more control data it contains, the more it is entered into UUIE by the message originator. Less text can be, and UUIE is already a very limited length Have (128 octets). Another issue attempts to send a simple text message between MSC and SMS-C It happens in the figure. The conventional technology is a network interface signal PDC mobile application. Mobile Application Part (MAP) protocol Is to use to send a simple text message. With methods other than GSM, Using MAP to transport simple text messages to Shin SMS-C is It is relatively inefficient and therefore a problem. For example, fixed ISDN (and PD) C operator) is the No. 7 signal base (number 7 signaling) based) ISDN User Department (ISDN) user part; ISUP) Use the protocol. Therefore, the use of the MAP protocol is a fixed ISDN. Introduced the MAP protocol to (and the PDC operator) and made it an existing ISU It also forces the use over the P protocol, which complicates the design. It also significantly increases sex and at least adds significant software costs. To. In addition, many SMS-Cs are integrated with voice mail system centers. And such a voicemail system center is IS to communicate with SMC Existing IS for communication between SMS-C and MSC because it uses the UP protocol It is advantageous to use the UP protocol. In addition, MSC and SMS-C Using the MAP protocol to transfer release instructions between is SMS-C Does not allow the connection to the MSC to be terminated immediately, which makes the line unnecessary Restrained over a long time interval. Abstract of the invention Digital telecommunications without special simple character message service interface The main idea is to provide a method and device for transporting simple text messages within the system. It is the purpose of Ming. Hardware and hardware used to store and ship simplified text messages It is also an object of the present invention to minimize software design complexity.

Figure 1 is a top-level block diagram of a digital cellular mobile telecommunications system. A method and an apparatus for transporting a simplified character message according to a preferred embodiment of the present invention. Shown. The example shown in Figure 1 shows how simple characters can be used in a PDC system type configuration. Indicates whether the route can be selected for the sage. However, shown The examples are for explanatory purposes only, and the present invention is so limited. Not intended. In essence, the concept of the invention is called, as explained in more detail below. Control interface Q.931 or any similar model Transporting simplified text messages within mobile or fixed digital telecommunications systems Can be used for For example, the present invention is North American PCS1900, European GS. It can also be realized by M or fixed ISDN method. The cellular communication system 10 shown in FIG. 1 is based on the data communication line 13. Simple character message service center (SMS-C) 14 connected to Simple Character message terminal (short message terminal; SMT ) 12 is included. The user sends or receives a simple text message via SMT12. Can be trusted, SMT12 is multiple in a data network, for example PSTN It may be one of the SMTs of. SMS-C14 is a data network and one of the PLMNs Acts as a simple character message interface unit with. this In the embodiment, the PLMN shown in FIG. 1 is of the PDC method operating in Japan. The version. SMS-C14 is a data communication line 15 Connected to Gateway Mobile Service Exchange Center (GMSC) 16 .. SMS-C14 memorizes simple character messages and sends them to SMT12. From now on (and also to and from one or more mobile stations in the PLMN) .. SMS-C14 is a GSM model of SMS-C or a similar model. May be. For example, SMS-C14 is for Ericsson Therefore, it may be an MXE memory and shipping exchange system manufactured. Instead of this SMS with GMSC configured to store and ship simple text messages -C14 may be replaced. As such, the SMT12 is a GMSC (eg GM) It will be directly connected to SC16). GMSC16 is home location by signal network (eg No.7) 17. Connected to the register (HLR) 18. HLR18 (for example, cellular Individually for all subscribers registered for PLMN (in communication system 10) A database for storing and controlling subscriber data. HLR18 Is also the current location of each of the subscriber mobile stations (ie, the M where each mobile station is currently resident). Contains information about the SC location area). For mobile incoming simple text messages , GSMC16 must determine the position of the mobile station being called. G MSC16 contacts HLR18, HLM18 currently has a called mobile station Respond with the address of the MSC. For mobile incoming simple text messages, HLR18 is M through signal network 19. Communicates with SC20, and GMSC16 uses the ISUP protocol to communicate data Communicate with MSC 20 through line 21. However, mobile outgoing simple characters For messages, GMSC16 needs to determine the current location of the calling mobile station Since there is no SMS-C14, it is on the data communication line (not specified here). Therefore, it can be directly connected to MSC20. The MSC20 is a gate locatio n register; GLR) 22 is included and this register is in the MSC20 area It is a database that contains information about all the mobile stations whose current position is detected. The visitor location register (VLR) may replace GLR22. PD In the C environment, the VLR / MSC combination is referred to as the Visited MSC (VMSC). .. As the mobile station roams into the new MSC area, the G connected to that MSC The LR requests information from HLR18 about the mobile station. At the same time, GLR , The current location of the mobile station (eg, the MSC area where the mobile station is currently located) ) Inform HLR18. Therefore, mobile incoming simple character messages On the other hand, from HLR18, GMSC16 is M where the called mobile station is currently stationed. Get the address of the SC. GMSC16 is the correct M for simple character messages Reroute to SC. When the simple character message arrives at the MSC, the M Where is the mobile station located in the SC-related GLR (eg, where? Can know and switch messages to that mobile station. In the embodiment shown in FIG. 1, the MSC 20 is based on the data communication line 23. Connected to station 24. Base station 24 is connected to and by this MSC20 It is one of several controlled base stations. Each base station identifies a set of radio channels Define a cell that works with one of the. Mobile incoming simple text message looks like this Can be transmitted from base station 24 to mobile station 26 through various wireless signal channels .. For mobile outgoing simple text messages, the messages are the same or different. Can be transmitted from mobile station 26 to base station 24 through wireless signal channels .. In FIG. 2, a mobile transmission simple character message is set according to a preferred embodiment of the present invention. It is a sequence diagram which shows the step to perform and the step to transmit. Generally preferred The method is Q.931 New simple character message control data in the call control setting message. Information element (short message control data info To introduce rmation element; SMCIE) Q.931 b Using the locking shift procedure, this call control configuration message is sent from the mobile station to the MSC. Is sent to or vice versa. SMCIE contains simple character message control data And Q.931 UUIE (optional) includes simple text message text Can be taken. Preferably, Q.931 locking shift 6 (operator identification) ) Information elements are used to create and define SMCIE. The preferred method is It also transports simple character message control data between SMS-C and MSC. ISUP initial address message (initial ad) in a new way Use the access transport parameters in dress message; IAM) .. For example, referring to FIGS. 1 and 2, the user can use the simple character message on the mobile station 26. Send a simple text message to the other party (for example, SMT12 or another mobile station) When he / she wants to send, he / she accesses the menu and the other party's destination. Address, simple letter message center address (eg, callee number or S MS-C address), validity period (eg SMS-C discards message) Some simple character message control data, such as the period up to) and the preferred delivery time. Can be selected. Preferably, the user puts alphanumeric characters into the memory location in the mobile station. Type a letter. In step 30 of Figure 2, the user presses (for example, the "send" key ". "Instruct (or by) the mobile station 26 to send a simplified text message. der) , the mobile station will send the specified simple character message text. And insert and send control data into the Q.931 call control configuration message. Move Station 26 sends a simple text message to Q.931 UUIE, SMS- C address Q.931 Called party number information element (called party nu) mber information element; CPNIE), and simplified The rest of the easy character message control data (Q.931 Call control setting locking shift To the new SMCIE (created and defined by code set 6 information elements) insert. In this example, it follows the Q.931 protocol, so S MCIE is led by the Rocking Shift 6 Information Element field and this feel Do is led by the UUIE field. However, the present invention is It is not intended to be limited to sea urchin, and is it practically possible in these fields? Even in the order of, it falls into the concept of invention. Preferably, for call setup, mobile station 26 requires a signal channel MSC2 To 0 Q.931 Call control configuration message through random access channel Send. Q.931 Call control setting message is a simple character message text Contains information and control data, received by base station 24, and MSC2 Combined to 0. Step 30 is in free mode (no calls in progress) It may be activated by the mobile station you create. If, for example, inquiry call assistance Service (Inquiry Call Supplementary Serv If ice) is activated, step 30 is already for existing calls. It is also activated by the mobile station using the established connection. In that case, simple characters Sage Q.931 Call settings are forwarded with a different call reference than the existing call reference And the simple character message call is treated as a separate call. In an alternative example Is a simple character message, self-supporting dedicated control channel SDCCH), low speed related Control channel (slow associated channel; SACCH ), Or can be transmitted through other channels, such as non-dedicated channels. In step 32 of Figure 2, the MSC20 asks Q.931 "call pr". oceeding) Transports call control messages to mobile station 26. This message The simple text message has been validated and sent to SMS-C14. Indicate to the mobile station that the process is in progress. In a preferred embodiment, the SMCIE inserted in the Q.931 call control configuration message , Contains multiple 8-bit data fields (octets). For example, SMC IE has an 8-bit SMCIE identifier field and a separate 8-bit SMCIE length Includes indicator fields. SMCIE is also a simple character message included in SMCIE. An 8-bit identifier field and each of the sage control data elements (validity, etc.) Includes a separate 8-bit length indicator field. These identifier fields and length markers As for the knowledge field, is MSC20 (and finally SMS-C14) SMCIE? It makes it possible to efficiently extract simple character message control data. SMC IE may also include a simple character message version data field Yes, this field is an 8-bit identifier field and an 8-bit length indicator fee Including Ludo. This simple character message version data field is S Simple character message control device that will be included in the subsequent fields of MCIE Can be used to notify incoming SMS-C (14) about data model Wear. This feature allows incoming SMS-C to easily distinguish between mobile station models. (For example, old mobile terminals send different control data than new terminals. It can be said). SMCIE fields and data that can be included here An example of the field will be described in more detail below. In step 34, the MSC20 receives a simplified text message text and control day. Q.931 Call control setting message including data is sent to SMS-C14. GSM Then, the simple character message is the standard network interface signal GSM mobile application part (M) Transported from the MSC to the incoming SMS-C using the AP) protocol. GSM Other methods use MAP to transport simple text messages to incoming SMS-C. Using the protocol is relatively inefficient and therefore problematic. example For example, fixed ISDN uses the No. 7 signal-based ISDN user section (ISUP). To do. Therefore, the use of the MAP protocol leads to a new MAP to fixed ISDN. Enter and force it to be used again on top of the existing ISUP protocol It also becomes. Furthermore, many SMS-Cs are integrated with the voice mail system center And such voice mail system centers communicate with the MSC Because it uses the ISUP protocol, SMS the existing ISUP protocol -It is advantageous to use it for communication between C and MSC. In this example, this The problem is, using ISUP, a simple text message from MSC to incoming SMS-C Resolved by transporting text and control data. In step 34, the MSC20 uses the ISUP interface protocol. Then send the simple text message text and control data to SMS-C14. To. ISUP initial address message from MSC20 (initial a) ddress message; IAM) is the called person received from mobile station 26 Carry number (destination SMS-C address) data and caller (mobile station) number data Send. MSC20 is a simple sentence received from the mobile station in Q.931 UUIE Extract text message text data and use the text data as ISU P User-User Service 1 Insert into an explicit parameter field. ISU In the P protocol, the Q.931 information element is ISUP access transport (access). transport; AT) Allows transport within the field. MSC IS locking shift 6 elements and MSCIE simple character message control data Insert into the UP AT field. Therefore, SMCIE data to MSC Can be "transparently" transferred to SMS-C through Can (ie, any explicit recognition of SMCIE data transfer is also required by the MSC) Not requested). In step 36, SMS-C14 is the received brief statement in ISUP IMA Extract and analyze textual message text and control data. The result of the analysis is It is returned as simple character message control data in SMCIE. locking· Shift 6 elements and SMCIE are ISUP release (REL) messages. Packed within the AT parameter of sage. As a user option, SMS- C14 responds to a well-formatted message by saying "goodby". ) Or message received a nd processed) so that it can be declared (state) ISUP User of REL Message-User Service 1 Optional within explicit parameters Sional return text message (return) text message) can be sent. SMS-C (for regular calls) Address complete message ; ACM) is returned to MSC20, and SMS-C is a simple character message process. After completing the process, the connection to the MSC will be released. Especially after ACM An important technical advantage of freeing connections (REL) is line retention time as much as possible. Is to minimize. In step 38, the MSC20 receives an optional user from SMS-C. -User text messages can be inserted into Q.931 UUIE To. Optional UUIE and b received from SMS-C within AT parameters 6 elements of locking shift and SMCIE are standard Q.931 call control disconnect message Transferred to mobile station 26 (via base station 24) within the network. This is the mobile station and network Start releasing the link between and. Simple text messages to mobile subscribers should be submitted to SMS-C from the fixed terminal. Can be done again. For example, referring to Fig. 1, the user in SMT12 is simple. When a user wants to send a text message to a mobile station (26), the user has a menu Access and mobile station number (callee number, i.e. CPN), validity period , And simple character message control data such as preferred delivery time can be selected. it can. The user can also type in the simplified text message text To. Simple text messages and texts come from a variety of sources (eg, typed English). It can be entered by numbers, voice, facsimile, telex). Simple Character message text and selected control data go through data line 13. And transferred to SMS-C14. FIG. 3 sets a mobile incoming simple character message according to a preferred embodiment of the present invention. It is a sequence diagram which shows the step to perform and the step to transmit. After all, suitable The law Q.9 simple character message control data information element, ie SMCIE 31 To introduce in call control setting message Q.931 Locking shift move Use order. However, for mobile incoming simple text messages, SM The CIE is transmitted from the MSC to the mobile station. Simple character for mobile transmission explained above Similar to the sage method, SMCIE for mobile incoming simple text messages is simple Contains character message control data, and Q.931 UUIE is a simple character message Can contain text. Preferably, Q.931 locking shift 6 (Operator specific) Information element field creates and defines SMCIE Used for Predetermined delivery time (or if the simplified text message cannot be delivered , Later time), SMS-C14 sends a simple text message to the destination mobile station (26) ) Is intended to be delivered. In step 40 of Figure 3, SMS-C14 is dedicated Allocate the line to MSC20 and use ISUP IAM for a simple character message Transport to MSC. ISUP IAM is a calling category party category; CPC) data can be included and this data Is used to indicate to the MSC20 that the incoming message is from SMS-C Used. Therefore, the MSC, if its function is by the destination mobile station (26) If activated, guarantees that simple character messages are not forwarded can do. MSC can also ship CPC to HLR18 , This has the ability of the destination mobile station to receive a simplified text message on the HLR. That is, you are an SMS subscriber). If you don't have the ability Then you can terminate the message. ISUP IAM also CPN (addressed mobile station number) and call Person number (calling party) number; CLN), including CLN Includes the address of the outgoing SMS-C (14) in this embodiment. Use ISUP Person-User Service 1 Explicit parameter field is simple character message text Can include strikes. ISUP AT message requires rocking shift 6 Includes raw and SMCIE. SMICE takes the place of a simple character message system Includes your data (eg, validity period, time when the message was sent, etc.). If IS If MSC determines that the fields in UP IAM are properly formatted For example, MSC is an ACM (eg, "information O" Send "K)" to outgoing SMS-C. In step 42 (to GMSC16 if the destination mobile station is a resident receiving MSC) Therefore, the MSC20 (already determined) is the base station (24) and the destination mobile station (26). Use standard paging and verification procedures to establish initial links between. example For example, the MSC20 is the specific location where the destination mobile station made the most recent contact with base station 26. Instruct the area to submit a page. Mobile station 26 is defined by a base station Respond to the page by sending an incoming call condition report to the specific cell. this The report is passed to the MSC, which is therefore the cell in which the mobile station responded. Identification information (identity) can be determined. MSC20 is a mobile station Performed confirmation (26), allocated traffic channels, and allocated Instruct the mobile station to switch to the rough channel. In addition, the signal is Achieved on the signal link on the traffic channel of. At step 44, where the signal channel link was established, MS C20 sends a Q.931 call control configuration message (via base station 24) to the mobile station. Send to 26. Call control configuration messages are SM in the CLN information element field Q.931 UUIE (inserted by MSC) with S-C14 address Contains simple character message text in the field. MSC20 is an incoming call (i ncoming) From IAM AT parameters to locking shift 6 information elements And SMCIE are extracted and included in the configuration message. Create SMCIE Using the locking shift 6 information element for the MSC20, SMCIE Insert and transfer simple character message control data in the field. In step 46, Q.931 Simple character message via call control setting message If the message is received, the mobile station 26 will hear that this is a simple text message. Immediately acknowledge that it is not a voice call due to the presence of SMCIE in the configuration message To understand. Therefore, the mobile station has released Q.931 (release comp). lete; REL COMP) Send a call control message to MSC20 and this M The SC immediately terminates the link between mobile station 26 and base station 24. Liberation Messe The page is a response to the original simple text message / text information. As an answer (in Q.931 UUIE of REL COMP message) option Can include null text messages. For example, this release message Can also declare "message received". Or the release message is , For example, depending on the number of beverage cans or bottles remaining in the vending machine. It can also be from the vending machine that answers. Mobile station REL COMP message It is also possible to insert a locking shift 6 element and SMCIE within this In the message, SMCIE is the result of the delivery of the original simplified character message (for example, "me". Contains information about "sage received" or "full memory". Release message Control data for is preferably included in the SMCIE field. In step 48, the MSC20 was returned in the ISUP REL message. 6 elements of locking shift and SMCIE, and optional returned users Send a text message to SMS-C14. 6 elements of locking shift And SMCIE are carried within the AT parameters of the REL message, and opsi The returned user text message is included in the UUIE parameter. .. Therefore, simple character message control data is included in the ISUP AT parameter. Is done. Thereby, SMS-C will be informed about the result of message delivery. .. The REL message releases the connection from MSC20 to SMS-C14. If SMS-C14 intends to deliver a simplified text message to the destination If the mobile station is in use or unreachable, the MSC20 will Along with the "cause" code (using ISUP REL messages) Send a release message to SMS-C. Why is the cause code a simple character message Identify the reason why the delivery could not be delivered. Outgoing SMS-C (14) Intended to memorize this message and deliver it at other times. Also If the destination subscriber activates the standard auxiliary "waiting for call" service, even if it is transferred By establishing a parallel second call with other call references, even when the motive is in use To transfer a mobile incoming simple text message from MSC20 to the mobile station. Can be done. FIGS. 4A to 4D show the Q.931 call control setting message according to the preferred embodiment of the present invention. A model that can be used to transfer simple character message control data in the It is a relational diagram which shows the typical SMCIE. Refer to Figures 4A-D for the illustrated MSCI E contains multiple 8-bit (octet) data fields. 1st data The field (octet 1) contains a locking shift 6 code set (figure). 4A).

Preferably, the locking system The foot field is a separate element that precedes SMCIE. The second fi in the illustration The field contains the SMCIE identifier, and the third field contains the length of the SMCIE. Mu. The fourth field contains the simplified character message version, which is used It can be used to determine the type of terminal and the control data to be transported. .. The fourth field is also, for example, a simple text message from a mobile station to SMS-C. Simple text such as submission or delivery of a simple text message from SMS-C to a mobile station Includes text message service requests. The fifth data field in the illustrated SMCIE is from (simplified character message) Includes credit address identifier. This field is also the length of the outgoing address information element , Whether the number in the address is odd or even, the number given for the outgoing address Model (subscriber number, international number, etc.), numbering plan identification (ISDN / telephone numbering plan, Telex numbering plan, etc.) and address numbers (alphanumeric numbers or binary coded decimal) Contains data on the card (BCD) model). The sixth data field in SMCIE is the SMS-C Timestamp De Includes data (delivery date, hour, minute). 7th data field for outgoing SMS-C Message reference data set by the mobile station (circulation from 0 to 255) Includes simple character message numbers). The eighth data field (Figure 4B) is Deferred time distribution (coded similar to SMS-C timestamp data) Includes deferred time delivery data .. The ninth data field is (similar to SMS-C timestamp data) Includes validity period data (also coded). The tenth data field in the illustrated SMCIE is, for example, a mobile station or SM. Simple text message received by T, Temporary Error 1 (SMS-C is still mailing) Intended to deliver the message), permanent errors (destination that cannot be delivered, etc.), and Temporary error 2 (SMS-C no longer intends to deliver the message) Includes message state data, such as. The eleventh data field is, for example, Used, like Standard Message, Group 3 Facsimile, X400 Includes message protocols. The twelfth data field (Figure 4C) is coded (similar to the calling address). Includes the destination address. The thirteenth data field is a message notification request (Requested / not requested notification report) and priority (regular or high priority) including.
