TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of communication technology, in particular to a communication method and apparatus. BACKGROUND

[0003] Global system for mobile communication (GSM) is a standard proposed by European Standardization Committee in 1992, which uses data communication technology and unified network standard to ensure communication quality and develop more new services for users. For example, the global system for mobile communications for railways (GSM-R) is used in railway scenarios. GSM-R provides a general communication platform for railway staff, and is a system facility designed, constructed and used for railway transportation production and railway informatization services, which mainly completes functions such as railway dispatching communication, station communication, emergency communication, section communication, public communication, transportation information transmission, etc.

[0004] However, with the GSM entering the end of the industry and the deployment of future mobile communication systems, such as the deployment of future railway mobile communication system (FRMCS), a coexistence scenario of new and old generations of networks (such as GSM-R and FRMCS) will inevitably appear.

[0005] In the scenario of coexistence of two generations of networks, how to conveniently and efficiently realize communication between two generations of networks is a problem that the industry needs to care about. SUMMARY

[0006] The present application discloses a communication method and apparatus, which can use the protocol capability of one generation of network side nodes in two generations of networks to communicate with the other generation of network side nodes through a gateway, thereby conveniently and efficiently realizing communication between two generations of networks.

[0007] The present application will be described from different aspects below. It should be understood that the embodiments and advantages of different aspects below can be mutually referred to.

[0008] In a first aspect, a communication method is disclosed, which can be performed by a communication device, the communication device can be a first mobile communication system side node or a module (e.g., a chip) of the first mobile communication system side node. The method can include: interacting, by the communication device, first information with a second mobile communication system side node through a gateway, the first mobile communication system being different from the second mobile communication system; and wherein the first mobile communication system side node and the gateway communicate with each other using a first protocol, the first protocol including at least one of an ISDN user part (ISUP) protocol, a CAP protocol, and a MAP protocol.

[0009] In an embodiment, the first mobile communication system side node interacts with the gateway based on the first protocol. Therefore, the first mobile communication system side node can reuse the process of interacting with other network elements through the first protocol, thereby avoiding re-development of the first mobile communication system side node and achieving communication between the first mobile communication system and the second mobile communication system conveniently and efficiently.

[0010] The interaction can be replaced by transmission or communication, etc. That is, the first mobile communication system side node interacts with the second mobile communication system side node through the gateway, which can mean that the first mobile communication system side node transmits the first information to the second mobile communication system side node through the gateway or the first mobile communication system side node communicates the first information to the second mobile communication system side node through the gateway.

[0011] For example, the first mobile communication system side node sends the first information to the gateway, and the gateway forwards the first information to the second mobile communication system side node. For another example, the second mobile communication system side node sends the first information to the gateway, and the gateway forwards the first information to the first mobile communication system side node.

[0012] The first mobile communication system side node and the gateway communicate with each other using the first protocol, that is, the first mobile communication system side node sends the first information to the gateway using the first protocol, or the gateway sends the first information to the first mobile communication system side node using the first protocol. For example, the first mobile communication system side node sends a first message to the gateway, the first message being an ISUP message or a CAP message or a MAP message.

[0014] In the embodiments of the present application, the GSM-R side node interacts with the IWF based on the first protocol.

[0066] The technical terms and related technologies designed in the present application are introduced as follows.

[0067] 1、GSM system

[0068] The GSM system is composed of three main subsystems connected with each other, and connected with users through certain network interfaces. The three subsystems are base station subsystem (BSS), network and switching subsystem (NSS) and operation supporting subsystem (OSS). The MS subsystem is usually regarded as part of the BSS. MS is the equipment used by users in the GSM mobile communication network, and the types of MS mainly include vehicle-mounted station and handheld station (mobile phone).

[0069] In the GSM system, the BSS is responsible for providing and managing the transmission path between the NSS and the MS, especially including the management of the radio interface between the MS and the functional entities of the GSM system. The NSS is responsible for the management of the communication service, and ensures the establishment of communication between the MS and the relevant public communication network or other MS. That is, the NSS does not directly communicate with the MS, and the BSS does not directly communicate with the public communication network. The MS, BSS and NSS constitute the entity part of the GSM system. The OSS provides control, maintenance and management of these actual operating parts for the operator.

[0070] The BSS is composed of two functional entities, a base transceiver station (BTS) and a base station controller (BSC). The BTS is responsible for radio transmission, and the BSC is responsible for control and management.

[0071] The BTS is a base transceiver station and an important component of the BSS. It is controlled by the BSC, and completes the conversion between the BSC and the radio channel, and realizes the radio transmission of the air interface between the BTS and the MS and the related control functions. The BTS is mainly composed of a baseband unit, a carrier frequency unit, a control unit and a sky feed unit, etc. The baseband unit is mainly used for necessary voice and data rate adaptation and channel coding, etc.; the carrier frequency unit is mainly used for modulation / demodulation and transmission and reception of radio frequency signals, etc.; the control unit is used for the operation and maintenance of the BTS. The sky feed unit is mainly used for the branching / combinating of radio frequency signals and converting the radio frequency signals into electromagnetic waves or converting electromagnetic waves into radio frequency signals.

[0072] The BSC is the control part of the BSS, and completes the management of various interfaces and undertakes the management of the radio resources and the radio transmission parameters. The BSC is mainly composed of the following parts: the management, control and processing part of the related interface; the public processing part; the switching part.

[0073] The BSS is composed of one BSC and one or more BTSs. One BSC can control tens of BTSs according to the traffic volume requirement. The BTS can be directly connected with the BSC, or can be connected with the BSC in a remote control connection mode through the base station interface equipment (BIE).

[0074] The core of the GSM network is the MSC, which controls the traffic of all BSCs, provides switching functions and connections with other functions in the system, and provides interface functions with the fixed network, which connects mobile users with each other, mobile users and fixed network users. The MSC can obtain all the data required for user location registration and call request from three databases in the system, i.e., the HLR, VLR and authentication center (AUC). In addition, the MSC also requests to update part of the data in the database according to the latest information obtained. As the core of the network, the MSC also supports functions with mobile features such as location registration, handover, automatic roaming and other network functions.

[0075] 2. Coexistence scenario of GSM-R and FRMCS

[0076] FIGS. 1A and 1B are schematic diagrams of two coexistence scenarios of GSM-R and FRMCS provided by the embodiments of the present application. FIG. 1A exemplarily shows that the railway includes a stock railway and an extension line, and the junction of the stock railway and the extension line is called a railway junction point, wherein the stock railway is a region covered by GSM-R, and the extension line is a region covered by FRMCS (such as LTE-R or 5G-R). GSM-R and FRMCS coexist on the railway, and there is a scenario of interaction between a GSM-R side node and a FRMCS node, such as the interconnection and intercommunication between a GSM-R side node (such as a device on train 1) in the region covered by GSM-R (i.e., the GSM-R network) and a dispatch station or a terminal user in the region of the FRMCS network; for another example, the interconnection and intercommunication between a FRMCS side node (such as a device on train 2) in the region covered by FRMCS (i.e., the FRMCS network) and a dispatch station or a terminal user in the region of the GSM-R network.

[0077] FIG. 1B exemplarily shows that the railway region is a dual-layer overlapping network region of GSM-R and FRMCS, i.e., the region is covered by both GSM-R and FRMCS. There is a scenario of interaction between a GSM-R side node and a FRMCS node on the railway region, such as a device on train 1 being a GSM-R side node, i.e., the device on train 1 uses the GSM-R network, and train 2 being a FRMCS side node, i.e., the device on train 2 uses the FRMCS network, so that the scenario of interaction between the device on train 1 and the device on train 2 is the scenario of interaction between a GSM-R side node and a FRMCS node.

[0078] The cluster column dispatching service is one of the key core services of the railway, and with the coexistence deployment of GSM-R and FRMCS, because the coexistence scenario includes early support for GSM vehicle-mounted or handheld terminal equipment, support for LTE or NR (referred to as L / NR) vehicle-mounted or handheld terminal equipment, or multi-mode terminal equipment that supports GSM / LTE / NR, the terminal equipment needs to communicate with each other and the terminal equipment and the dispatching station of the command center for cluster voice communication, so there is a demand for supporting cluster voice, group call, function addressing, location addressing and other key services between the two generations of wireless communication systems.

[0079] In the above-mentioned GSM-R and FRMCS coexistence scenario, the GSM-R side node and the FRMCS side node can interconnect and interoperate through the IWF, and the industry has discussed that the SIP protocol is used for communication between the GSM-R side node and the IWF.

[0080] The inventors of the present application found that because the SIP protocol is less used in the GSM-R network, the method needs to re-develop the GSM product at the end of the industry.

[0081] Therefore, the present application provides a communication method and device, which can avoid re-development of the GSM-R side node by using the protocols (such as ISUP protocol, CAP protocol and MAP protocol) that the GSM-R side node already has to communicate with the IWF gateway. Understandably, because the ISUP / CAP protocol / MAP protocol is a common communication protocol of the GSM-R side node and is widely used in commercial applications, the GSM-R side node uses the ISUP / CAP protocol / MAP protocol to communicate with the gateway, and the communication process can reuse a large number of existing GSM-R mechanisms, which is more suitable for reducing the impact on the GSM product at the end of the industry.

[0082] Based on the above, in order to better understand the communication method and related device proposed by the present application, the system architecture of the embodiments of the present application is described below.

[0083] Please refer to FIG. 2, which is a system architecture diagram of a communication system provided by an embodiment of the present application.

[0084] The communication system includes a first mobile communication system side node 201, a gateway 202 and a second mobile communication system side node 203.

[0085] The first mobile communication system is different from the second mobile communication system; the gateway 202 is configured to forward information between the first mobile communication system side node 201 and the second mobile communication system side node 203, the first mobile communication system side node 201 and the gateway 202 communicate with each other by using a first protocol, and the first protocol includes at least one of a integrated services digital network user part protocol, a mobile network enhanced logic custom application part protocol, and a mobile application part protocol; the second mobile communication system side node 203 and the gateway 202 communicate with each other by using a second protocol, and the first protocol is different from the second protocol.

[0086] In some embodiments of the present application, the first mobile communication system side node 201 is a GSM-R side node, the gateway 202 is a network interworking function node, and the second mobile communication system side node 203 is an FRMCS side node.

[0087] For example, FIG. 3 is a schematic diagram of a system architecture of another communication system provided by an embodiment of the present application. The communication system includes at least one GSM-R side node, an IWF, and at least one FRMCS side node. As shown in FIG. 3, the GSM-R side node includes a GSM-R MS, a GSM-R BTS, a BSC, and a MSC / VLR, and the FRMCS side node includes an FRMCS MS, an FRMCS BTS, a core network device, and an MCX, wherein the core network device includes an evolved packet core (EPC) or a 5G core. In the present application, the MSC / VLR is used to represent the MSC and / or the VLR.

[0088] For example, the GSM-R MS and / or the FRMCS MS can be a handset or a cab radio.

[0089] In some other embodiments of the present application, the FRMCS side node interacting with the IWF can be a mission critical push-to-talk (MCPTT) server (or MCPTT for short).

[0090] It should be noted that the above-mentioned FIG. 3 takes the railway scenario as an example, and in some other embodiments of the present application, the above-mentioned communication system can also be applied to other scenarios, and the above-mentioned first mobile communication system and the above-mentioned second mobile communication system can be a group network communication system in other scenarios, and the present application does not limit this.

For example, more or less devices in communication with the gateway can also be included, and for the sake of brevity, they are not described one by one in the drawings.

[0092] In addition, in the system architecture as shown in FIG. 2 and FIG. 3, although the first mobile communication system side node 201, the gateway 202 and the second mobile communication system side node 203 are shown, the application scenario can not be limited to including the first mobile communication system side node 201, the gateway 202 and the second mobile communication system side node 203, and other devices can also be included, which is not limited by the present application.

[0093] In combination with the above-mentioned system architecture, a communication method provided by the embodiments of the present application is described below.

[0098] S401: The first mobile communication system side node sends first information to the gateway using a first protocol, and the first protocol includes at least one of ISUP protocol, CAP protocol and MAP protocol.

[0099] Correspondingly, the gateway receives the first information sent from the first mobile communication system side node.

[0100] The first mobile communication system side node sends first information to the gateway by using a first protocol. The first mobile communication system side node can send a first message to the gateway, and the first message includes the first information. The first message can be an ISUP message, a CAP message, or a MAP message. That is, the signaling carrying the first information from the first mobile communication system side is an ISUP message, a CAP message, or a MAP message.

[0101] In a possible implementation, the first mobile communication system side node is an MSC, and the first protocol is an ISUP protocol and / or a CAP protocol.

[0104] S402: The gateway forwards the first information to the second mobile communication system side node by using a second protocol, and the first protocol is different from the second protocol.

[0105] Correspondingly, the second mobile communication system side node receives the first information sent by the gateway.

[0106] The gateway forwards the first information to the second mobile communication system side node by using a second protocol. The gateway can send a second message to the second mobile communication system side node, and the second message includes the first information. The second message can be a message corresponding to the second protocol. For example, the second protocol is a SIP protocol, and the second message is a SIP message. That is, the signaling carrying the second information from the gateway can be a message corresponding to the second protocol, such as a SIP message.

[0107] In an implementation, when the gateway receives a message (for example, the first message described above) sent by the first mobile communication system side node to the second mobile communication system side node, the gateway can process the first message into a second message, and then send the second message to the second mobile communication system side node. For example, the gateway can process the first message into the second message by the following process: parsing the first message by using the first protocol to obtain the first information; and then processing the first information based on the second protocol to obtain the second message.

[0108] For example, the first mobile communication system can be a GSM-R, and the first mobile communication system side node is a GSM-R side node. The gateway can be an IWF. The second mobile communication system can be an FRMCS, and the second mobile communication system side node is an FRMCS side node.

[0109] For example, the first mobile communication system side node is an HLR, the second mobile communication system side node is a network element (e.g., MCX) for group dispatch, and the first information is information of GSM-RMS (e.g., GSM-RMS function number, etc.). Then, the network element for group dispatch can save the first information after receiving the first information.

[0110] S403: The second mobile communication system side node sends second information to the gateway by using a second protocol.

[0111] Correspondingly, the gateway receives the second information sent from the second mobile communication system side node.

[0112] In the embodiment, the second mobile communication system side node sends a third message to the gateway, the third message includes the second information, and the third message is a message corresponding to the second protocol. For example, the second protocol is SIP protocol, and the second message is a SIP message. That is, the signaling carrying the second information from the second mobile communication system is a message corresponding to the second protocol, such as a SIP message.

[0113] S404: The gateway forwards the second information to the first mobile communication system side node by using a first protocol.

[0114] Correspondingly, the first mobile communication system side node receives the second information sent from the gateway.

[0115] In the embodiment, the gateway sends a fourth message to the second mobile communication system side node, the fourth message includes the second information, and the fourth message is an ISUP message or a CAP message or a MAP message. That is, the signaling carrying the second information from the gateway is an ISUP message or a CAP message or a MAP message.

[0116] In an implementation, when the gateway receives a message (e.g., the third message) sent from the second mobile communication system side node to the first mobile communication system side node, the gateway processes the third message into the fourth message, and then sends the fourth message to the first mobile communication system side node. For example, the gateway processes the third message into the fourth message by performing the following operations: parsing the third message by using the second protocol to obtain the second information; and processing the second information based on the first protocol to obtain the fourth message.

[0117] The method shown in FIG. 4 includes many possible implementation schemes. Some of the implementation schemes will be described below with reference to FIGS. 5 to 7. It should be noted that the related concepts, operations, or logical relationships not explained in FIGS. 5 to 7 can be referred to the corresponding descriptions in the embodiment shown in FIG. 4.

[0118] In the present application, the embodiments shown in FIGS. 5 to 7 can be taken as a separate embodiment, and the embodiments shown in FIGS. 5 to 7 can be independent of the technical solution of FIG. 4; and some steps in the embodiments shown in FIGS. 5 to 7 can also be taken as a separate embodiment.

[0119] FIG. 5 is a flow diagram of another communication method provided by an embodiment of the present application.

[0120] In the embodiments of the present application, the gateway is taken as the IWF; the first mobile communication system side node interacting with the gateway is the GSM-R side node, which is the HLR, referred to as HLR(G); and the second mobile communication system side node interacting with the gateway is the FRMCS side node, which is the MCX. Taking the MCX as an example, the communication method provided by the present application is described in detail.

[0121] In the embodiments of the present application, the functions performed by the IWF can also be performed by a module (for example, a chip) in the IWF, the functions performed by the HLR(G) can also be performed by a module (for example, a chip) in the HLR(G), the functions performed by the MCX can also be performed by a module (for example, a chip) in the MCX, the functions performed by the MS(G) can also be performed by a module (for example, a chip) in the MS(G), and the functions performed by the MS(L / NR) can also be performed by a module (for example, a chip) in the MS(L / NR). The MS(L / NR) is the FRMCS side MS, such as the LTE side MS or the NR side MS. For example, the MS(L / NR) can be a vehicle-mounted station.

[0122] For example, in the embodiments of the present application, the first information is the function number of the MS(G), the second information is information for indicating the successful registration of the function number, steps S501 to S506 are the function number registration process (referred to as registration process 1) of the MS(G), and steps S507 to S508 are the function number registration process (referred to as registration process 2) of the MS(L / NR). The present application does not limit the order of the registration process 1 and the registration process 2, and the two registration processes can be executed in sequence or simultaneously.

[0123] In the present application, the function number can be a train function number, a locomotive function number, a dispatch function number, or other function numbers, which are not limited by the present application.

[0124] As shown in FIG. 5, the method can include the following steps:

[0125] S501: The MS(G) sends the function number of the MS(G) to the HLR(G) through the MSC / VLR(G).

[0126] In one implementation, the MS(G) can send an unstructured supplementary service data (USSD) string to the HLR(G), where the USSD string includes the functional number of the MS(G), e.g., the USSD string can include first request information including information indicating registration of the functional number. In other embodiments of the application, the USSD string can also be used to indicate deregistration or query of the functional number.

[0127] where the MS(G) is a GSM-R side MS. For example, the MS(G) can be a cab radio. In some embodiments, the MS(G) can send a first functional number registration request to the MSC / VLR(G), where the request carries the functional number of the MS(G) and is used to request registration of the functional number. The MSC / VLR(G) can then send a second functional number registration request to the HLR(G), where the request carries the functional number of the MS(G) and is used to request registration of the functional number. The first and second functional number registration requests can also be referred to as Follow Me service requests (FM-Request).

[0128] S502: The HLR(G) sends a first request to the IWF, where the request includes the functional number of the MS(G) and is a MAP message.

[0129] In one implementation, after receiving the USSD string, the HLR can check whether the MS(G) is subscribed to the Follow Me service. If the HLR determines that the MS(G) is subscribed to the Follow Me service, the HLR sends a USSD string including the request information to the MCX via the IWF. If the HLR determines that the MS(G) is not subscribed to the Follow Me service, the HLR does not send a USSD string including the request information to the MCX via the IWF.

[0130] Optionally, the first request can also be referred to as an HLR FM-Request.

[0131] S503: The IWF sends a second request to the MCX, where the request includes the functional number of the MS(G) and is a SIP message.

[0132] S504: The MCX sends a first response message to the IWF, where the message includes information indicating successful registration of the functional number and is a SIP message.

[0133] In one implementation, after receiving the USSD string, the MCX can establish the correspondence between the functional number and the Mobile Station International ISDN (MSISDN) number of the MS (G) if it is determined that the USSD string is used to indicate registration, and then return the first response message (also referred to as an acceptance request or a USSD response) to the MS (G).

[0134] In some embodiments of the present application, the MCX deletes the correspondence between the functional number and the MSISDN number of the MS (G) registered originally if it is determined that the USSD string is used to indicate deregistration, and returns a USSD response to the MS (G), which is used to indicate successful deregistration of the functional number; or the MCX can query the correspondence between the functional number and the MSISDN number of the MS (G) registered if it is determined that the USSD string is used to indicate query, and returns a USSD response to the MS (G), which includes the query result, i.e., the MSISDN number corresponding to the functional number.

[0135] S505: The IWF sends a second response message to the HLR (G), which includes information used to indicate successful registration of the functional number, and the second response message is a MAP message.

[0136] Optionally, the second response message can also be referred to as an HLR FM-Response.

[0137] S506: The HLR (G) sends information used to indicate successful registration of the functional number to the MS (G) via the MSC / VLR (G).

[0138] In some embodiments, the HLR (G) can send a first functional number registration response to the MSC / VLR (G), which carries information used to indicate successful registration of the functional number; and then the MSC / VLR (G) sends a second functional number registration response to the MS (G), which carries information used to indicate successful registration of the functional number, wherein the first functional number registration response and the second functional number registration response can also be referred to as a functional number response (FM-Response).

[0139] S507: The MS (G) saves the registered functional number.

[0140] In one implementation, after receiving the USSD response containing information used to indicate successful registration of the functional number, the MS (G) can store the registered functional number (i.e., the functional number of the MS (G)).

[0141] In some embodiments of the present application, after the MS(G) receives the USSD response for indicating the successfully deregistered function number, the MS(G) can delete the function number originally registered by the MS(G); or after the MS(G) receives the USSD response including the query result, the MS(G) can display the query result.

[0142] S508: The MS(L / NR) sends a third request to the MCX, the third request including the function number of the MS(L / NR), the third request being a SIP message.

[0143] S509: The MCX sends a third response message to the MS(L / NR), the third response message being a SIP message and being used for indicating the successfully registered function number. In some embodiments of the present application, after receiving the third request, the MCX saves the function number of the MS(L / NR); and then sends the third response message to the MS(L / NR).

[0150] In some embodiments, the authorized administrator can perform forced logout of the function number for the specified function number and MSISDN number, for example, the MCX-IN can send a first notification message to the MCPTT in response to a user operation of the authorized administrator, the message including information for indicating logout of the function number. Exemplarily, the information for indicating logout of the function number can be a Notify message for indicating logout of the function number in a USSD string.

[0151] S602: The MCPTT sends a second notification message to the IWF, the message including information for indicating logout of the function number, the message being a SIP message.

[0154] S605: The MS(G) deletes the locally saved function number.

[0155] Optionally, the MS(G) deletes the MSISDN number corresponding to the locally saved function number.

[0156] For example, the MS(G) deletes the function number and the MSISDN number in the USSD string.

[0158] S607: The HLR(G) sends a second response message to the IWF, the message including information for indicating successful logout of the function number, the message being a MAP message.

[0159] S608: The IWF sends a third response message to the MCPTT, the message including information for indicating successful logout of the function number, the message being a SIP message.

[0160] S609: The MCPTT sends a fourth response message to the MCX-IN, the message including information for indicating successful logout of the function number.

[0161] FIG. 7 is a flow diagram of another communication method according to an embodiment of the present application.

[0162] The embodiment of the present application takes the scenario of FIG. 3 as an example; takes the gateway as the IWF; takes the first mobile communication system side node interacting with the gateway as the MSC / VLR (G), which refers to the GSM-R side MSC or VLR; and takes the second mobile communication system side node interacting with the gateway as the MCX as an example, and introduces the communication method provided by the present application in detail.

[0163] The functions performed by the IWF in the embodiment of the present application can also be performed by a module (for example, a chip) in the IWF, the functions performed by the HLR (G) in the embodiment of the present application can also be performed by a module (for example, a chip) in the HLR (G), the functions performed by the MCX in the embodiment of the present application can also be performed by a module (for example, a chip) in the MCX, the functions performed by the MS (G) in the embodiment of the present application can also be performed by a module (for example, a chip) in the MS (G), and the functions performed by the MS (L / NR) in the embodiment of the present application can also be performed by a module (for example, a chip) in the MS (L / NR).

[0164] For example, in the embodiment of the present application, the first information is the FN of the MS (L / NR), and the second information is the MSISDN number corresponding to the FN of the MS (L / NR).

[0165] As shown in FIG. 7, the method can include the following steps.

[0166] S701: The MS (G) sends a setup request to the MSC / VLR (G), the request including the FN of the MS (L / NR), and the request being used to request to establish a call connection with the MS (L / NR).

[0167] S702: The MSC / VLR (G) sends a first request message to the IWF, the message including the FN, and the message being an ISUP message or a CAP message.

[0168] In some embodiments, the MSC / VLR (G) sends the first request message to the IWF after receiving the setup request.

[0169] For example, the first request message can be an initial detection point (IDP) message.

[0170] S703: The IWF sends a second request message to the MCX, the message including the FN of the MS (L / NR), and the message being used to request the MSISDN number corresponding to the FN, and the message being an SIP message.

[0171] S704: The MCX sends a reply message to the IWF, the message including the MSISDN number corresponding to the FN, and the message being an SIP message.

[0172] In some embodiments, after receiving the second request message, the MCX can first check whether the FN has been registered, and if the FN has been registered and has an MSISDN number (i.e., the MSISDN number corresponding to the FN) for establishing an association relationship, the MCX can send a reply message to the IWF, the message including the MSISDN number corresponding to the FN.

[0173] S705: The IWF sends a connect message to the MSC / VLR (G), the message including the MSISDN number, the message being an ISUP message or a CAP message.

[0174] In some embodiments, after receiving the reply message, the IWF obtains the MSISDN number from the reply message, the reply message being a SIP message; and then sends a connect message to the MSC / VLR (G), the connect message being an ISUP message or a CAP message.

[0175] S706: When the MSC / VLR (G) determines that the MSISDN number is a number of an L / NR user, the MSC / VLR (G) sends a call origination message to the IWF, the message being an ISUP message or a CAP message.

[0176] For example, when the MSC receives the connect message and determines that the MSISDN number is a number of an L / NR user, the MSC sends a call origination message to the IWF, the call origination message being an initial address message (IAM). The L / NR user can be an MS on the LTE side or an MS on the NR side.

[0177] S707: The IWF establishes a call connection with the MS (L / NR).

[0178] S708: The IWF sends a call completion message to the MSC / VLR (G).

[0179] For example, the call completion message can be an address complete message (ACM).

[0180] S709: The MSC / VLR (G) sends an alerting message to the MS (G).
