Method for assigning telecommunication services

State of the art

0001The invention relates to a method for allocation of telecommunications services according to the preamble of the main claim made.

0002From the GSM specification (GSM) 02:11, Version 4.9.0 it is known to assign mobile stations user classes. It share the user classes the amount on the mobile stations randomly in ten classes. A base station can now grant or deny a permit for each of these classes of users, on a random access channel request messages. The granting of licenses or -verweigerung is the mobile stations by means of a signaling channel notified.

0003From EP 0658014 A1 a cellular telecommunication system is known in which Orbital satellite communication channels assign participants in cells. Each subscriber unit is programmed with a class identifier. During periods when it is desirable to access a satellite to some restricted class or limit class sets, the satellite sends a list of blocked Klassenidentifikatoren, the only such stations allow access to the communication system, whose Klassenindifikatoren are not on the list of blocked classifiers. The Periods of limiting access to the satellite, for example, periods its high load.

0004From US 5,313,653 it is known that a resource arbiter new services messages sends to the communication units when the corresponding communication unit a new service is assigned or there is a change of allowed services.

ADVANTAGES OF THE INVENTION

0005The method with the features of the main claim has the advantage that information signals to said at least one subscriber station be transmitted containing information about which of the telecommunications services the at least one Subscriber station are allocated for use. To this Way is a more flexible allocation of Telecommunications services to at least one Subscriber station possible. This flexible allocation of Telecommunication services provides the opportunity not only an allocation of all telecommunications services or none at all telecommunications service to the at least one subscriber station before, but also the Allocating a portion of the available Telecommunications services to at least one Subscriber station. Resources of the telecommunication network can so effectively the subscriber stations of Telecommunications network are made available, so that certain telecommunications services the Greater provided at least one subscriber station available can be.

0006are of the measures listed in the dependent claims Advantageous further developments and improvements of the Main claim specified method possible.

0007It is advantageous that different at different times Telekommunikatonsdienste of at least one Subscriber station are allocated. In this way, the resources of the telecommunications network more effectively and more flexible at least one subscriber station are dynamically allocated for use.

0008It is particularly advantageous that the Telecommunication services of at least one Subscriber station depending on the News traffic in the telecommunications network be allocated. In this way, even at high News traffic in the telecommunications network certain telecommunications services through targeted Prohibit other telecommunications services the Greater make at least one subscriber station.

0009Further flexibility of the method of allocation of telecommunications services and thus of resources Telekommunikatonsnetzes arises advantageously by grouping the subscriber stations in User classes, the telecommunications services to Subscriber stations depending on their user class be allocated.

0010A further advantage is that the at least one Subscriber station by the information signals, preferably by means of a bit pattern, communicated, which telecommunication service or which combination of Telecommunications services from a predefined set at least one telecommunications service and / or at least one combination of Telekommunikatonsdiensten which is allocated at least one subscriber station. On thus requiring the information signals a minimum Dataset and therefore demand for your transfer less time at an unchanged data rate or a lower Data rate with an unchanged transmission time.

0011Embodiments of the invention are shown in the drawing represented and in more detail in the following description explained. 1 shows a section of a Telecommunication network, figure 2 shows a first bit pattern for the Allocation of telecommunications services and 3 a second bit patterns for the allocation of Telecommunications services.

Description of Embodiments

0012In Figure 1100 indicates a base station of a Mobile Network trained telecommunications network. On Such a mobile network is usually constructed cellular, each radio cell of the mobile network of a Base station is powered. The base station 100 thus biases one radio cell to the mobile network, in accordance with Figure 1 a first subscriber station 5, a second Subscriber station 10, a third subscriber station 15 and a fourth subscriber station 20 are arranged. Both four subscriber stations 5, 10, 15, 20 should it exemplified by mobile stations, such as Mobile phones, wireless phones, or the like. at Thus, the embodiments described herein, the first subscriber station 5 as the first mobile station, the second Subscriber station 10 as the second mobile station, the third Subscriber station 15 as the third mobile station and the fourth Subscriber station 20 is formed as a fourth mobile station be. A network operator of the mobile network provides a predetermined number of telecommunications services. in the following example, three different Telecommunications services are provided by the network operator can. In this case, as a first Telekummunikatonsdienst for example to provide a data sharing service, the is used by the mobile stations 5, 10, 15, 20 can, for short data burst to the base station 100 via a random access channel 30, of the following formed by way of example as a RACH (Random Access Channel) should be to transfer. As a second Telecommunications service, an example be provided capacity requirement Service, in which the RACH is used by the mobile stations 30 5, 10, 15, 20 allowed to separate data channels for data transmission request. As a third telecommunications service may for example to provide a Sprachrufdienst wherein the RACH used by the mobile stations 30 5, 10, 15, 20 may be to initiate voice transmissions or continue. The three Telekommunikatonsdienste can individually and / or in any combination to Mobile stations 5, 10, 15, 20 by the network operator to use be allocated.

0013The telecommunication services need to from the corresponding mobile station via the base station 100 in Network operators are requested. The Telecommunication services are doing the RACH 30 Mobile stations 5, 10, 15, made accessible to the twentieth On the RACH 30 can usually messages from multiple Mobile stations are sent to the base station 100th On This allows messages of different mobile stations collide with each other. confirmed, the base station 100 therefore properly received messages in which they appropriate acknowledgment or confirmation on another, not shown in FIG 1 channel, For example, a paging channel, to those Mobile stations sends back whose messages they has properly received. The telecommunications services are usually on the RACH from the mobile stations 30 5, 10, 15, 20, requested or made available.

0014In the event that the message is a mobile station on the RACH 30 collides with another message, can not find a proper receipt of this message in the base station 100 instead, so that the base station 100 also no Confirmation information to the corresponding mobile station may return. Therefore, the mobile station transmits, after a predetermined period during which no acknowledgment information from the base station 100 has been received, the message again threatens RACH 30 to the base station 100. In this way, an overload of the RACH 30, which thus user-initiated requests for Telecommunications services through the appropriate Mobile stations through its limited transmission capacity limited.

0015Overloading of the RACH 30 can be avoided, that the network operator to use the Telecommunication services for the individual mobile stations 5, 10, 15, 20 restricts targeted RACH 30th there can individual telecommunications services, for example, only temporarily for certain classes of users of mobile stations or permanently preference will be provided. According to the described embodiments of Figure 1 is a first user class 35, the first the Mobile station 5 and the second mobile station 10 comprises. Furthermore, a second user class 40 is provided the third mobile station 15 and the fourth mobile station 20 includes. However, it may also be provided for each Mobile station to provide a separate user class. It could also be provided with different user classes provide number of mobile stations. Furthermore, it is possible to have more than two mobile stations in a user class provide. The network operator can now Telecommunications services to individual mobile stations in Depending on their belonging to one of two User classes 35, 40 allocate. This means that the two Mobile stations 5, 10 of the first user class 35 same allocated telecommunications services from the network operator will. Analogously, also the mobile stations 15, 20 of the second user class 40 same allocated telecommunications services. The mobile stations allocated 5, 10 of the first user class 35 Telecommunications services can from the Mobile stations 15, 20 of the second user class 40 allocated telecommunications services differ. The the mobile stations of the two user classes 35, 40 However allocated telecommunications services can also be equal. The network operator shall inform the individual Mobile stations 5, 10, 15, 20 by information signals from the base station 100 to the respective mobile station 5, 10, 15, 20 transfer, which the Telecommunication services of the network operator of the corresponding mobile station 5, 10, 15, 20 are allocated. This is representative of all the mobile stations 5, 10, 15, 20 with reference to the allocation of Telecommunication services of the network operator to the first Mobile station 5 described in FIG. 1

0016The base station 100 transmits at predetermined times Information signals to the first mobile station 5. Information signals can according to figure 1 a Signaling channel 25, which by way of example as broadcast control channel BCCH is to be formed, be transmitted. Here, with the information signals at the prescribed times each a bit pattern to the first mobile station 5 transmitted. The bit pattern can in a first embodiment include information about which telecommunication service and / or combination of telecommunication services from a predefined set of telecommunications services to the first mobile station 5 is assigned. When the predetermined amount of Telecommunications services, these are the already described telecommunications services, such as Data consumer service, capacity and requirement Service Sprachrufdienst. Since the bit pattern for not only first Mobile station 5 but also to all other mobile stations 10, 15, 20 also over the signaling channel 25, which as described as BCCH and thus as a point-to-multipoint channel is formed so that all the mobile stations same information at the same time get sent is to those allocated to them notified telecommunications services, including the bit pattern the allocated telecommunication services for each User Class 35, 40. The corresponding bit pattern is shown in Figure 2 illustrated therein and designated by the numeral 45th It comprises a first Bitmusterabschnitt 105 for the first User class 35 and a second Bitmusterabschnitt 110 the second user class 40. Both Bitmusterabschnitte 105, 110 each comprise 3 bits. A first bit 51 of the first Bitmusterabschnitts 105 of the first bit pattern 45 are thereby whether the data service using the mobile stations 5, 10 the first user class is assigned to the 35th A second bit 52 of the first Bitmusterabschnitts 105 of the first bit pattern 45 specifies whether the capacity requirement Service to allocated mobile stations 5, 10 of the first user class 35 is. A third bit 53 of the first Bitmusterabschnitts 105 the first bit pattern 45 indicates whether the Sprachrufdienst the allocated mobile stations 5, 10 of the first user class 35 is. A first bit 61 of the second Bitmusterabschnitts 110 the first bit pattern 45 indicates whether the Data usage service to mobile stations 15, 20 of the second assigned user class 40th A second bit 62 of Bitmusterabschnitts second 110 bit pattern of the first 45 specifies whether the capacity requirement Service to allocated mobile stations 15, 20 of the second user class 40 is. A third bit 63 of the second Bitmustersabschnitt 110 the first bit pattern 45 indicates whether the mobile stations 15, allocated 20 of the second user class 40 of Sprachrufdienst is. A logic one of the respective bit indicates that the corresponding telecommunications services are the appropriate Mobile stations is allocated and a logic zero indicates that the relevant telecommunications services to respective mobile stations is not assigned. According to Figure 2 are the first Bitmusterabschnitt 105 of the first Bit pattern 45, the first bit and the second bit 51 to 52 One set and the third bit 53 is set to zero. The means that the mobile stations 5, 10 of the first User Class 35 of the data service use and the Capacity requirement Service and the combination of assigned to both services. The Sprachrufdienst is However, the mobile stations 5, 10 of the first user class 35 not assigned. In the second Bitmusterabschnitt 110 of first bit pattern 45 are the first bit 61, the second bit 62 and 63, the third bit is set in each case to one. The means that all telecommunications services, and all three possible combinations of two or three Telecommunications services to mobile stations 15, 20 of second user class are allocated 40th Using a from User of the corresponding mobile station in the mobile station introduced access card, on which the User class of the mobile station is stored, detects the Mobile station belonging to their respective User class and can therefore target the relevant Bitmusterabschnitt the corresponding bit pattern to access, order assigned to him in this user class Telecommunications services and / or combinations of Telecommunications services to recognize. The allocated Telecommunications services, the corresponding then use the mobile station on the RACH 30, as in Figure 1 is illustrated with reference to the first mobile station 5, the News to use the assigned her Telecommunications services over the RACH 30 to the Base station 100 transmits. According to Figure 2 are for each User class three bits required in a number of three telecommunications services of each mobile station tell which of the three telecommunications services their are assigned singly or in any combination. For two user classes gives this the length of the first Bit pattern 45 to 2 x 3 = 6 bits. In general, the calculated Length of the first bit pattern 45 from the product of the number the user classes and the number of possible Telecommunications services.

0017In the event that one of the first Bitmusterabschnitt Bit pattern 45 includes only a single bit, which on one is set, only the associated telecommunications service assigned to the corresponding mobile station, Combinations with other telecommunications services are not possible, since their bits are set to zero.

0018Another embodiment for forming a Bit pattern for the allocation of telecommunication services to a mobile station is shown in FIG. 3 The above the signaling channel 25 transmitted information signals in this case comprise a second bit pattern 50, the first Mobile station 5 notifies that telecommunications service or combination of telecommunications services from a predetermined amount of at least one Telecommunications service and / or at least one Combination of telecommunication services the first Mobile station 5 is assigned. The same applies to the Allocation of telecommunications services or combinations of telecommunications services to the other mobile stations 10, 15, 20. In this case, to all mobile stations 5, 10, 15, 20 a second bit pattern 50 via a respective Signaling channel transmitted, the first one Bitmusterabschnitt 115 for the first user class 35 and a second Bitmusterabschnitt 120 for the second User Class 40 includes. The first mobile station 5 and the Therefore, the second mobile station 10 of information on the allocated to them telecommunications services through evaluation the first Bitmusterabschnitts 115 of the second bit pattern 50 and the third mobile station 15 and the fourth mobile station 20 receive information about their assigned des.zweiten telecommunications services through evaluation Bitmusterabschnitts 120 of the second bit pattern 50. The first Bitmusterabschnitt 115 of the second bit pattern 50 includes a 71 first bit and a second bit 72. The second Bitmusterabschnitt 120 of the second bit pattern 50 comprises also a first bit 81 and 82. According to a second bit Figure 3 is the first bit 71 of the first Bitmusterabschnitts 115 of the second bit pattern 50 is set to zero and the second bit 72 of the first Bitmusterabschnitts 115 of the second Bit pattern 50 is set to one. The first bit of the 81 second Bitmusterabschnitts 120 of the second bit pattern 50 is set to one and the second bit 82 of the second Bitmusterabschnitts 120 of the second bit pattern 50 is on set zero.

0019According to the second embodiment is made of a lot a telecommunications service and two combinations of Telekommuniktionsdiensten for allocation to the Mobile stations 20 may be provided 5, 10, 15,. It includes this quantity in the described embodiment the Sprachrufdienst first volume element, the combination from Sprachrufdienst and capacity requirement Service as second quantity element and the combination as Sprachrufdienst, capacity requirement Service and Data using service as a third element amount. Only one a quantity element can the corresponding mobile station be allocated. The number of this quantitative element is this binary by the 2 bits of the respective represented Bitmusterabschnitts the second bit pattern 50th According to the embodiment of Figure 3 is therefore the Mobile stations 5, 10 of the first user class 35 due to the Bit combination 0-1 in the first 115 of the Bitmusterabschnitt second bit pattern 50, that is a binary one, the first Volume element, so only the allocated Sprachrufdienst. The mobile stations 15, 20 of the second user class 40 however, due to the combination of bits 1-0 in the first Bitmusterabschnitt 115 of the second bit pattern 50, ie a binary two-the second set element and thus both the Sprachrufdienst and the Capacity requirement Service allocated for use. Of the Volume could a fourth element to the amount be added bit combination 0-0, without the number of bits would be increased per Bitmusterabschnitt. For a lot with a maximum of four major elements are per user class 2 bits showing the quantity allocated element required so that in the second embodiment according to Figure 3 in two user classes, the length of the second Bit pattern x 2 = 50 2 is 4 bits. General results the length of the second bit pattern 50 of the second Embodiment, the product of the number of User classes and the whole to the next higher number rounded two-logarithm of the number of Volume elements.

0020The information signals are transmitted to the base station 100 the mobile stations 5, 10, 15, 20 at predetermined times, preferably transmitted at regular intervals. Of the Network operators, the telecommunications services in Depending on the message traffic in Telecommunications network, thus depending on a expected utilization of the RACH 30 each Mobile stations 5, 10, 15, 20, depending on their allocate user class and by certain Telecommunication services a particular user or class certain user classes temporarily or permanently bevorrechtigt provide. Since the News traffic in the telecommunications network with changed the time, also changes the expected Utilization of the RACH 30 with time, so that to usually different times different telecommunications services by corresponding changes in the Bitmusterbelegung Mobile stations 5, 10, 15, 20 are allocated. The from the GSM specification 02.11, version 4.9.0-known case of the Allocation of all telecommunications services or, alternatively, none Telekommunikationssdienstes to the corresponding Mobile stations 5, 10, 15, 20 represents a special case of the Process is inventive. If this one User class assigned to all telecommunications services, so in accordance with the embodiment of Figure 2 all Bits of associated Bitmusterabschnitts set to one. If the mobile stations of a user class no allocated telecommunications services, as are in accordance with the Embodiment of Figure 2, all bits of the associated Bitmusterabschnitts zeroed.

0021A relief of the RACH 30 can be obtained additionally characterized be that a repetition counter and / or a Repeat distance is provided. The repeat counter specifies the maximum number of allowed retries for repeated sending of a message from the corresponding mobile station via the RACH 30 to the Base station 100 in the event of collision with a Message to another mobile station. Of the Repeat distance is a stochastic measure of the time interval until the next recurrence of the each mobile station to the base station 100 via the RACH 30 message sent. The smaller the number of allowable retries and the greater the Repeat distance, the greater the discharge of the RACH 30. The repetition counter and / or the Repeat distance may at regular intervals together with the bit pattern of the allocated Telecommunications services to corresponding mobile stations optionally together with further radio cell-specific Information on the associated signaling channel 25 be communicated.

0022The inventive method can in a cellular network according to the UMTS standard (Universal Mobile Telecommunication System), according to the GSM standard, or the like implements will.

0023The inventive method is not limited to use limited in a cellular network, but also generally in Telecommunications networks for allocating Telecommunications services to subscriber stations of Telecommunications network applicable, the Telecommunications network, for example a may be wired landline.
