Description of the Invention: [Technical Field of the Invention] The present invention relates to a method of providing a service to an inbound roaming user in a visited public land mobile network (VPLMN), wherein the user uses a home An mobile terminal subscribed to within the Public Land Mobile Network (HPLMN), the method comprising the steps of: roaming the mobile terminal into the visited public land mobile network (VPLMN); and operating the local land mobile network ( A home location register (HLR) within the HPLMN) exchanges service information with a visitor location register (VLR) within the visited public land mobile network (VPLMN) for use in the visiting public The provision of services to the mobile terminal is implemented within the Land Mobile Network (VPLMN). The present invention is further directed to a service subscription adaptation entity for providing services to inbound roaming users within a visited public land mobile network (VPLMN) in accordance with the above method. Furthermore, the present invention relates to a messaging transfer point (STP) and a telecommunications system including the above service subscription adaptation entity. [Prior Art] ^ With the introduction of mobile telecommunications services decades ago, the number of mobile users of such services has grown widely, and today's mobile telecommunications services are fully integrated into modern life. A large number of mobile service providers are currently available, and each provider provides mobile services through one or more mobile telecommunications networks in one or several countries or regions. The commercial success of mobile telecommunications services is primarily based on the implementation of these services wirelessly and in any location, regardless of where the user is located. This is particularly true for mobile telephony, which remains the main driving force behind the commercial success of mobile telecommunications services. Due to the success of the business and the increased number of mobile users, the demand for mobility of telecommunications services is positive. Wen κ stopped with the day and became more and more strict. In addition, users themselves become more mobile, and at the same time, 'the users of today are far more introduced than in the early 1970s: when they first served the service (the earliest commercial operation public mobile phone network in i97i year) Start at Caves: ARP) Travel more. Nowadays, users not only want to be able to make calls anywhere, but also want to be able to use all the telecommunications services they routinely use, such as voice mail, call forwarding, virtual private network (VPN), calling number, anytime, anywhere. Identification, number portability, etc. This development has been going on for some time, and in order to meet these requirements, telecommunications providers have been involved in ongoing activities with the goal of introducing standards across industries. One of these standards is for custom applications of the Mobile Network Enhanced Logic (CAMEL) standard introduced under the Third Generation Partnership Project (3Gpp). CAMEL has evolved in the past as a mobile intelligence standard across the requirements of different vendor equipment for mobile GSM (Global Communications System) networks. The CAMEL feature has been provided within the GSM system to provide service even when the user is roaming (ie, being networked by a network different from his mobile terminal: a visited public land mobile network (VPLMN) » The network operator is still allowed to provide access to such subscriber services including operator specific services. Since the introduction of CAMEL, it has been in development for many years; and the CAMEL standardization has now reached CAMEL Phase 4. Earlier versions of the CAMEL standard have Gradually the development of several mobile telecommunications services is available. CAMEL Phase 1 supports a basic enhanced functionality at the top of regular voice and data calls. This feature is one of the features of the virtual private network (VPN) service. The basic version supports a large number of telecommunication services for roaming users in CAMEL Phase 4, such as conference beer calling, enhanced VPN services, and network initiated call setup. In CAMEL, monthly information is used by using CAMEL Subscription Information (CSI). Making it available for use in telecommunications networks. When a telecommunications service user (for example) from his home public land mobile network When the HPLMN) roams to a visited public land mobile network (VPLMN), the location is exchanged between the visitor location register (VLR) within the VPLMN and the home location register (HLR) within the HPLMN. In addition, the HLR within the HPLMN may transmit initiated CAMEL subscription information (0-CSI) to the VLR within the VPLMN. This 0-CSI identifies one or more services available to the user for use. His home network (HPLMN) roams outbound. In CAMEL Phases 3 and 4, the Network CAMEL Service Information (N-CSI) can also be used to provide services within the Public Land Mobile Network (VPLMN) visited. The services provided by the provider are available to inbound roaming users on this VPLMN. Depending on the preferences of the service provider within the VPLMN, N-CSI can be provided within the VLR to provide explicit availability in the visited network. Serving to roaming users. As a rule, the NCSI service information will not overwrite or replace the 0-CSI information provided by HPLMN' but in addition to the 0-CSI service, it can also trigger N-CSI services, for example to provide additional Service. Use N-CSI in both CAMELP and CAMELP. One of the disadvantages of triggering is that it only supports the provision of services supported under CAMEL Phase 3 or 4. This implies that the MSCs within the VPLMN and the service nodes 131176.doc 200915890 need to support CAMEL Phase 3 or 4. Mobile networks that do not support CAMEL Phase 3 or Phase 4 features do not support the use of an N-CSI trigger, and therefore it is not possible to provide specific services available to the inbound roaming users within the VPLMN. Even if VPLMN supports CAMEL Phase 3, if CAMEL Phase 4 is not supported, the use of N-CSI triggers will still be limited, and therefore the service providers within • VPLMN will not be able to provide additional services to the inbound at all times. SUMMARY OF THE INVENTION One object of the present invention is to provide services to inbound roaming users within a VPLMN, regardless of the standardized level supported by the VPLMN, specifically whether the VPLMN supports the CAMEL standard or which version is supported. This and other objects are achieved by the present invention in that, in accordance with a first aspect thereof, a method of providing a service to an inbound roaming user in a visited public land mobile network (VPLMN) is provided, wherein the user is using An mobile terminal in a public land mobile network (HPLMN), the method comprising the steps of: roaming the mobile terminal into the public land mobile network (VPLMN) of the visit; and acting on the public land of the home A home location register (HLR) within the network (HPLMN) exchanges with a visitor location register (VLR) in the visiting public-land mobile network (VPLMN) • service information for Providing the mobile terminal service within the visited public land mobile network (VPLMN); verifying that the service profile includes the public land mobile network (VPLMN) enabled by the public land mobile network (HPLMN) The home service subscription information for the service used by the mobile terminal; and when the service profile does not include the home service subscription information 131176.doc -10- 200915890 The visited Public Land Mobile Network (VPLMN) enables alternative subscription information for services available to the mobile terminal in the visited Public Land Mobile Network (VPLMN) and adds the alternate subscription information to the service profile. Used to store it in the visitor location register (VLR). According to the present invention, an alternate subscription is automatically generated within the VPLMN without any home service subscription information (specifically 0-CSI or Visiting Termination CAMEL Subscription Information (VT-CSI)) received from the HLR within the HPLMN. News. If the HLR does not provide any home service subscription information, the user will not have the CAMEL service for outbound roaming available to him and provided by the HPLMN within the VPLMN. In this case, by making alternative subscription information, the VLR " thinks ", the HLR has provided a 0-CSI or VT-CSI. Thus, by providing the alternate subscription information, the services identified in the alternate subscription information can be used by the inbound roamer within the VPLMN. In other words, the VPLMN may generate alternate subscription information containing service information that may be from a service used within the VPLMN, and because the alternate subscription information is used as one of the C- or C-SI or VT-CSI in the VLR, It is considered a regular O-CSI or VT-CSI so that the service provider of the VPLMN provides services to the inbound roaming users. The main advantage of this invention is that it can be applied to any type of mobile network, and is also explicitly applied to mobile telecommunications networks that only support CAMEL Phase 1 or Phase 2 and do not support Phase 3 or Phase 4. As noted above, this subscription information override is only generated when the home service subscription information cannot be obtained from the HPLMN. This is because it is undesirable to overwrite the O-CSI or VT-CSI provided by the HLR of the HPLMN. 13I176.doc 200915890 The home service subscription information may include any element 0 including a group that initiates subscription information (such as 0-CSI) and termination subscription information (such as VT-CSI). According to an embodiment of the present invention, This step of substituting subscription information is performed by a service adaptation entity (SSA) located within the visited public land mobile network (VPLMN). An advantage of facilitating the method of the present invention through a separate network entity is that it can be easily implemented in either

Specific. The method of the present invention can be implemented within the visited public land network (VpLMN) as a feature within the transmitting transmission point (STp), such as between the HLR within the HPLMN and the VLR within the VPLMN. . Thus, in this particular embodiment of the invention, the Service Subscription Adaptation Entity (SSA) may be a Sending Point (STP) within an existing mobile telecommunications network. In this case, the service subscription adaptation entity may be responsible for verifying whether the HPLMN provides home service subscription information (eg, 0-CSI or VT-CS:) 'and if this is not the case, it may also be responsible for generating the alternate subscription hole. Send this - Beixun to the inside of the VPLMN to add the replacement. Ding Yuebei recorded the service information for inbound roaming users. According to the J. ^ another embodiment of the present invention, wherein the home service subscription sfl includes initiating a subscription, and the alternative subscription information is in the same format as the originating subscription information. Specific: , , 5, this format may correspond to a format commonly used by the CAMEL standard to initiate a subscription (such as 0-CSI). According to a specific embodiment of the present invention, wherein the home service subscription information includes a termination subscription, the alternative subscription information is the same as the termination subscription information 131176.doc 200915890. In particular, this format may correspond to a format commonly used by the CAMEL standard to terminate subscription information (such as VT-CSI). In addition to generating the alternate subscription information, the VPLMN may provide a service (such as an alternate service indication), i.e., it has performed the step of generating the alternate subscription information. The VPLMN may also generate a service indication (such as a VPLMN service trigger indication) indicating that the service defined by the alternate subscription information has been invoked. Such service indications (alternative service indications or vpLMN service trigger indications) may be recorded in a call detail record (CDR) and/or may be sent to the HPLMN for use with the record. This is completely optional and the method of the present invention will work flawlessly without providing an alternative service indication. However, providing an alternate service indication as described above and one or both of the vpLMN service trigger indications supports charging and, where applicable, statistical analysis is performed within the VPLMN or at the HPLM. Since the home service subscription information is typically provided with or in response to the location update program, the present invention can be fully implemented as a feature within the program.

[Embodiment] In Fig. 1, reference numeral 1 is generally used to indicate a telecommunication system according to the present invention. The telecommunication system 1 includes a public land mobile network 1 O (HPLMN), which is subscribed to a mobile terminal 3 of a user 2; and a visited public land mobile network (VPLMN) 8 having a mobile terminal User 2 of 3 is currently roaming inside. Roaming occurs when user 2 travels with his mobile terminal 3 to one of the geographic areas covered by the Home Land Mobile Network (HPLMN) 10 and then enters one of the geographic areas covered by VPLMN 8, the user 2 Register with a Mobile Switching Center (MSC) within the VPLMN. This can occur at any particular time, for example, when terminal 3, which is in use, is not in use and is switched in a standby mode in one of the user 2's clothes pockets. In either case, the mobile switching center (MSC) 11 in the VPLMN 8 is notified of the mobile terminal 3 existing in the network. For this purpose, the mobile terminal 3 may, for example, inform the base station 4 of its presence via the radio signal 5, which forwards the signal to the mobile switching center (MSC) 11. The MSC 11 is connected to a plurality of other MSCs 12, 13 and 14 within the VPLMN 8. The MSC 1 1 is further coupled to a Service Control Point (SCP) 24, a Visitor Location Register (VLR) 25, and a Home Location Register (HLR) 26. In HPLMN 10, a plurality of Mobile Switching Centers (MSCs) 18, 19, 20 and 21 are interconnected. The MSCs 18 through 21 can be connected to a base station (such as the base station 17) for receiving incoming signals from the mobile terminals on the network. The MSC 20 is coupled to a Service Control Point (SCP) 28 within the HPLMN 10 and to a Home Location Register (HLR) 29 within the HPLMN 10. The VPLMN 8 and HPLMN 10 are interconnected by interconnects 27 to connect the MSCs 11 within the VPLMN 8 to the MSCs 20 within the HPLMN 10. Between the MSC 11 and the MSC 20, the VPLMN includes a Transmit Transfer Point (STP) 30 for routing between the VPLMN 8 and the HPLMN 10. In HPLMN 10, MSC 20 can be used as a messaging point. The originating transmission points receive all of the outgoing messages exchanged on the interconnect 27. Thus, in one embodiment of the invention, STP 30 includes Service Subscription Adaptation (SSA) as a functional entity. 131176.doc -16- 200915890 One embodiment of the method of the present invention within the telecommunications system 1 of FIG. 1 is schematically illustrated in a flow chart of FIG. Each of the network elements, entities, and parties performing any of the tasks of the method of the present invention is described in the header of Figure 2. In the first line, the action performed by the terminal 3 is performed under the responsibility of the user 2. The second, third, fourth and fifth rows of Fig. 2 describe the actions performed by the elements in the VPLMN 8 in the communication program. In particular, the elements in the VPLMN 8 include the MSC 11, HLR 26, VLR 25, and STP 30. The actions performed by the network entities (specifically, the MSC 20 and the HLR 29) in the HPLMN 10 are described in the two rightmost rows of Figure 2. In Figure 2, the method of the present invention begins in step 35 where the mobile terminal 3 notifies the MSC 11 that it has reached the geographic area of the VPLMN 8. Step 35 may be a conventional location update as understood by those skilled in the art. In step 36, the MSC 11 of the inbound roaming mobile terminal 3 is informed that the international mobile subscriber identity used by the terminal 3 is analyzed to determine the terminal 3 HPLMN, and identified this department HPLMN 10. At step 38, MSC 11 sends a location update 'which is dedicated to HLR 29 within HPLMN 10. The location update is received by STP 30 and forwarded to MSC 20 within HPLMN 10 at step 40. The location update is forwarded by the MSC 20 to the HLR 29 at step 42 (it should be noted that the MSC 20 performs the STP function within the HPLMN, but to prevent clarity of the problem 'here it is indicated as MSC 20 instead of STP ' otherwise this may Confused with STP 30), the HLR updates the current location of the mobile terminal 3 by the MSC 11 servo in the VPLMN 8 by the registration mobile terminal 3. The home location register (HLR) 29, as a reply 'in step 43' HPLMN 10 131176.doc -17-200915890, sends the service profile back to the VPLMN 8. This service material contains information about VPLMN 8 for service from the VPLMN 8 to the mobile terminal 3 and may therefore contain all kinds of basic, supplementary and other information. The provision of one or more CAMEL services to its outbound roaming subscribers at HPLMN 10 may be initiated by HLR 29 to initiate CAMEL subscription information (O-SCI), which may be identified outside of HPLMN 10 (eg, in VPLMN) The CAMEL service used by the user 2 of the mobile terminal 3 of 8). The service data provided by the HLR 29 is forwarded by the MSC 20 to the Signal Delivery Point (STP) 30 at step 45. In accordance with the present invention, at step 49, STP 30 receives the service profile from MSC 20 and verifies whether the received service profile includes initiating subscription information, i.e., 0-CSI. If hlr 29 does not send 0-CSI to VPLMN 8 when transmitting the service profile in step 43, then at step 49 STP 30 establishes that no 0-CSI exists in the service profile and thereby includes an alternative in the received service profile. The subscription information (not indicated as arrow 48) is forwarded and the alternate subscription information is forwarded to the MSC 11. The alternate subscription information 48 may include relevant information for providing services to the mobile terminal 3 by the VPLMN 8. It may, for example, contain address or routing information for SCP 24 in VPLMN 8, through which a number of value-added services may be provided to mobile terminal 3. The MSC 11 receives the service data transmitted by the STP 3, including the alternate subscription information. Since the alternate subscription information can be formatted into one of the conventional 0-CSIs from HPLMN 10, the method of the present invention is well understood at MSC " In other words, the alternate subscription information a will be treated as a regular 〇_131176.doc •18-200915890 CSI and will be forwarded to the VLR 25 for registration at step 5 (^MSC u. One of the benefits of this) The present invention can be easily implemented in existing mobile networks without having to implement changes and modifications to many network nodes and entities. Receiving alternative subscription information and other materials included in the service data (such as mentioned above) After that, VLr 25 is updated in step 51. The method steps performed by STp 3〇 in the above-described embodiments of the present invention are shown in more detail in FIG. 3 as a flowchart. In the flowchart of FIG. The data piece provided through the telecommunications network is schematically illustrated as a diamond. In step 55, the STP 30 receives the location update message 100 from the MSC 11 in the VPLMN 8 and forwards the location update message 1 to the HPLMN. MSC 20 in 10. MSC 20 forwards message 1 to HLR 29 in HPLMN 10 (refer to Figure 2, step 42). As a reply, in step %, STP 3 receives service data 110. The service data is transmitted through The MSC 20 is from the HLR 29 in the HPLMN 1〇 Provided (Fig. 2, steps 43 and 45). STP 30 now performs a verification in step 57 to establish whether the service profile 11 includes initiating subscription information (0-CSI). If the initiation subscription information is included in the service profile 110, then verification is performed. The result of step 57 will be affirmative, and then the process will continue at step 58, where the service profile 110 is forwarded to the MSC 11 within the VPLMN 8. If the result of the verification step 57 is negative, then the STP 30 is in the step 60. The alternate subscription information 120 is added to the received service profile. The alternate subscription information 120 can be obtained from a piece of end memory 59 that can be accessed by the STP 30, or can be retrieved from another entity within the VPLMN 8. In step 60, the After the subscription information is replaced, the service data 131176.doc -19-200915890 130 is sent to the MSC 11 in the VPLMN 8 at step 61. The modified service profile 130 includes the original service profile 110 and the alternate subscription information 120. The process then ends. The resumption may be resumed when STP 30 receives another location update or when STP 30 receives a data recovery message from MSC 11 in VPLMN 8.

This may be implemented by analyzing the CAMEL phase parameters that the STP 30 may have received from the MSC 1 1 in step 38. In this manner, STP 30 is not compatible with the GSM specification in the sense that STP 30 does not provide CAMEL subscription information to the MSC when MSC 11 has not explicitly or implicitly indicated that it supports the CAMEL subscription material for the service subscriber. For the sake of full understanding, it should be noted that many modifications and variations of the present invention are possible in light of the above teaching. The above examples are materialized to provide alternative subscription information in the event that the HPLMN does not provide any 〇_CSI. It should be understood that the present invention operates in a similar manner where the VT_csi information provided by the HPLMN is not available. The teachings of the present invention are equally applicable to this case as defined by the scope of the patent application, except that it is replaced by similar termination subscription information. Therefore, it should be understood that the present invention may be practiced in the context of the accompanying application patents, except that the text (10) of the present application clearly states.
