[0002] In the process of intercommunication between satellite mobile network and terrestrial communication network through IMS, due to the wide coverage of satellite communication, unlike terrestrial mobile communication network, users roam under the base station of the cell, thus having detailed access location information. Therefore, when users use satellite mobile terminals to make calls, they will encounter the following problems:

[0003] (1) When using a satellite mobile phone to call a fixed network phone, the user must dial the long-distance area code before selecting the local network. The area code cannot be automatically completed based on the access and location information to complete the call.

[0004] (2) When using a satellite mobile phone to make an emergency call (such as 110 or 119), the user must dial the long-distance area code before the emergency number, and cannot select the nearest emergency service desk based on access and location information (for example, one must dial 010-110 to represent the Beijing 110 hotline, and cannot select the nearby Xicheng District 110 hotline.

[0050] Embodiment 1

[0051] Figure 1 This is a flow chart of a satellite communication terminal calling method provided in the first embodiment of the present invention. This embodiment is applicable to the case where a user dials a terrestrial telephone via a satellite communication terminal. The method can be executed by a satellite communication terminal calling system, and the system device can be implemented in the form of hardware and / or software. Figure 1 As shown, the method comprises the following steps:

[0052] S110. When the satellite communication terminal initiates a call, the satellite communication terminal adds the terminal location information to the first initial SIP signaling to obtain a first SIP signaling to be sent, and sends the first SIP signaling to be sent to the IMS of the satellite mobile network.

[0053] In this embodiment, when a user uses a satellite communication terminal (such as a satellite phone) to call a ground fixed phone or an emergency phone, the current location of the terminal needs to be determined first. After obtaining the location information, the satellite communication terminal can initiate a Session Initiation Protocol (SIP) signaling call process, add the terminal location information to the first initial SIP signaling, and obtain the first SIP signaling to be sent. Then, the first signaling to be sent is sent to the satellite mobile network.

[0054] In an embodiment of the present invention, the satellite communication terminal adds the terminal location information to the first initial SIP signaling to obtain the first SIP signaling to be sent, which may include: the satellite communication terminal obtains the terminal location information through a positioning service or a human-computer interaction interface; adds a target header field to the first initial SIP signaling, and adds a first parameter corresponding to the terminal location information in the target header field to obtain the first SIP signaling to be sent.

[0055] Among them, the terminal location information may include country, city, longitude and latitude, etc.; the target header field may be a P-Access-Network-Info header field, and the first parameter may be the four parameters UE-Country (country where the user equipment is located), UE-City (city where the user equipment is located), UE-Longitude (longitude of the user equipment), and UE-Latitude (latitude of the user equipment).

[0056] Specifically, the satellite communication terminal can automatically obtain the current location information through the built-in positioning service. If the user wants to specify a location, the user can manually enter the location information through the human-computer interaction interface of the terminal. Then, a P-Access-Netw ork-Info header field is added to the first initial SIP signaling, and the four parameters UE-Country, UE-City, UE-Longitude, and UE-Latitude are added to this header field. Then, the parameter values ​​of the four parameters are set according to the current location information of the satellite terminal device, and the first SIP signaling to be sent is obtained.

[0057] For example, if the satellite communication terminal is located in Beijing, China, the longitude is 116.365868 east longitude, and the latitude is 39.912289 north latitude, then the following information can be added to the first initial SIP signaling:

[0058] P-Access-Network-Info: UE-Country=CN; UE-City=Beijing; UE-Longitude=E116.365868; UE-Latitude=N39.912289.

[0059] S120. The IMS of the satellite mobile network determines the terminal location information in the first SIP signaling to be sent, and supplements the called number based on the terminal location information and the base station location information of the terrestrial communication network.

[0060] In this embodiment, the IMS (IP Multimedia Subsystem) of the satellite mobile network can receive the first SIP signaling to be sent and identify the terminal location information therein, and then supplement the called number according to the terminal location information and the base station location information of the ground communication network, that is, supplement the called number with the long-distance area code, etc.

[0061] In an embodiment of the present invention, the IMS of the satellite mobile network determines the terminal location information in the first SIP signaling to be sent, which may include: in the IMS of the satellite mobile network, the first call session control component identifies the target header field in the first SIP signaling to be sent; when the target header field is identified, the first call session control component sends the first SIP signaling to be sent to the first dedicated server, so as to determine the terminal location information in the first SIP signaling to be sent through the first dedicated server.

[0062] The first session control component may be a CSCF (Call Session Control Function) component in the IMS of the satellite mobile network, which is responsible for processing the establishment, modification and termination of calls and sessions.

[0063] Specifically, in the IMS of the satellite mobile network, if the first session control component recognizes that the first SIP signaling to be sent includes a target header field, the first SIP signaling to be sent can be sent to the first dedicated server. The first dedicated server can be a dedicated application server (AS) in the IMS of the satellite mobile network, responsible for simulating the access location according to the terminal location information in the first SIP signaling to be sent.

[0064] In some possible implementations, supplementing the called number based on the terminal location information and the base station location information of the ground communication network may include: a first dedicated server determines whether a simulated base station exists based on the base station location information and the terminal location information; if so, adding a second parameter to the target header field, setting the parameter value of the second parameter to a first preset value, and supplementing the country code and / or area code of the called number based on the base station location information of the simulated base station.

[0065] The first dedicated server can compare the terminal location information with the data of the signal coverage range of the ground mobile base station to determine whether the terminal location is within the coverage range of a certain cellular mobile communication base station. If there are multiple base stations covering the location, the base station closest to the terminal or the center point of the coverage range is usually selected as the simulated base station.

[0066] If a suitable simulated base station is found, the first dedicated server uses the location area code (LAC) and cell identity (CI) of the base station as the simulated location area code (S-LAC) and simulated cell identity (S-CI) of this call. Then, the simulated location area code (S-LAC) and simulated cell identity (S-CI) are added to the P-Access-Network-Info header field of the SIP signaling, represented by S-LAC and S-CI parameters respectively.

[0067] At the same time, it is necessary to add a second parameter in the target header field and set the parameter value of the second parameter to the first preset value. For example, add the S-access-location parameter in the P-Access-Network-Info header field and set its value to yes, that is, the second parameter is the S-access-location parameter, and the first preset value is yes, which means that the simulated access location processing has been completed.

[0068] Furthermore, the country code and area code of the called number can be determined according to the analog access location, and the called number can be supplemented. For fixed numbers, the supplemented format is usually: country code + area code + user number. For emergency numbers, the supplemented format may include the country code, area code and the emergency number itself, and sometimes may also include a prefix or suffix to distinguish the specific service station.

[0069] S130. The IMS of the satellite mobile network adds the supplemented called number to the first SIP signaling to be sent to obtain a first target SIP signaling.

[0070] In this embodiment, the first dedicated server in the IMS of the satellite mobile network can add the supplemented called number to the first SIP signaling to be sent to obtain the first target SIP signaling, and after sending the first target SIP signaling to the first call session control component and completing other call processing, the first call session control component can forward the first target signaling to the Interconnection Border Control Function (IBCF) corresponding to the satellite mobile network.

[0071] S140. Send the first target SIP signaling to the IMS of the terrestrial communication network through the network interconnection border control function.

[0072] Specifically, the IBCF identifies S-access-location = Yes or = No in the P-Access-Network-Info header field in the first target SIP signaling. If yes, the P-Access-Networ k-Info header field and the called number are not modified and the signal is directly sent to the IMS network of the called operator, i.e., the IMS of the terrestrial communication network. The IBCF of the terrestrial communication network does not make any modification after receiving the signal and forwards it to the CSCF of the terrestrial communication network.

[0073] S150. The IMS of the terrestrial communication network executes a call flow of the satellite communication terminal to the called number based on the first target SIP signaling.

[0074] Specifically, a call originating from the satellite communication network is treated as a call originating from the simulated base station, and the subsequent call flow is completed.

[0075] In an embodiment of the present invention, the IMS of the terrestrial communication network executes a call process of the satellite communication terminal to the called number based on the first target SIP signaling, including: in the IMS of the terrestrial communication network, if the second call session control component recognizes that the parameter value of the second parameter in the first target SIP signaling is a first preset value, the call process of the called number is executed.

[0076] The second session control component may be a CSCF component in the IMS of the terrestrial communication network, and the first preset value may be a pre-set value, that is, the second parameter is the S-access-location parameter, and the first preset value is yes. In the IMS of the terrestrial communication network, if the second call session control component recognizes that the parameter value of the second parameter in the first target SIP signaling is the first preset value, indicating that the access simulation is completed, the call process of the called number is executed. By simulating the access location information processing and the called number supplement, the calls between the satellite communication network and the terrestrial communication network can be processed and routed more accurately, thereby ensuring the smooth progress of the call without the user manually adding the area code. The location information of the terminal is added to the call issued by the satellite communication terminal, and the call is simulated as a call issued from the ground base station according to the correspondence between the location and the coverage of the ground base station.

[0077] The technical solution of the embodiment of the present invention includes: when the satellite communication terminal initiates a call, the satellite communication terminal adds the terminal location information to the first initial SIP signaling to obtain the first SIP signaling to be sent, and sends the first SIP signaling to be sent to the IMS of the satellite mobile network. The IMS of the satellite mobile network determines the terminal location information in the first SIP signaling to be sent, and supplements the called number based on the terminal location information and the base station location information of the ground communication network; the IMS of the satellite mobile network adds the supplemented called number to the first SIP signaling to be sent to obtain the first target SIP signaling; sends the first target SIP signaling to the IMS of the ground communication network through the network interconnection boundary control function; the IMS of the ground communication network executes the call process of the satellite communication terminal to the called number based on the first target SIP signaling. In the embodiment of the present invention, the location information obtained by the terminal is simulated as the access location information of a base station in the ground communication network, and then the call initiated from the satellite communication network is treated as the call initiated from the simulated base station for call processing. Thereby solving the problem that the user will not be able to make calls (dial) as usual when using the ground communication network.

[0078] Embodiment 2

[0079] Figure 2 This is a flowchart of a satellite communication terminal calling method provided in the second embodiment of the present invention. Based on the above embodiment, this embodiment can not only implement access location simulation in the IMS of the satellite mobile network, but also implement access location simulation in the IMS of the terrestrial communication network. The specific implementation method can refer to the technical solution of this embodiment. Among them, the technical terms that are the same or corresponding to the above embodiment are not repeated here. Figure 2 As shown, the method includes:

[0080] S210. When the satellite communication terminal initiates a call, the satellite communication terminal adds the terminal location information to the first parameter of the target header field of the second initial SIP signaling, obtains the second SIP signaling to be sent, and sends the second SIP signaling to be sent to the IMS of the satellite mobile network.

[0081] The second SIP signaling to be sent may be the same as the first SIP signaling to be sent.

[0082] S220. The IMS of the satellite mobile network determines the terminal location information in the second SIP signaling to be sent, and determines whether a simulated base station exists based on the terminal location information.

[0083] In this embodiment, the location may be accessed by simulating the IMS of the satellite mobile network. The specific method may refer to the above-mentioned embodiment and will not be described in detail here.

[0084] It is understandable that, considering that the satellite communication network may not have simulation capabilities due to the lack of data such as the location and coverage of ground base stations, the technical solution of the present invention supports first completing the simulation in the satellite communication core network, and if it cannot be completed, the simulation can be further completed in the ground communication network. That is, in the process of interconnection and intercommunication, both parties cooperate to complete the simulation processing.

[0085] S230: In the absence of a simulated base station, add a second parameter to the target header field of the second SIP signaling to be sent, and set the parameter value of the second parameter to a second preset value to obtain a second target SIP signaling.

[0086] If the simulated base station is not determined based on the satellite communication network, a second parameter can be added to the target header field of the second SIP signaling to be sent, and the parameter value of the second parameter is set to a second preset value to obtain the second target SIP signaling. That is, in the P-Access-Network-Info header field, the value of the S-access-location parameter will be set to No.

[0087] S240. Send the second target SIP signaling to the IMS of the terrestrial communication network through the network interconnection border control function.

[0088] S250. When the IMS of the terrestrial communication network identifies the second preset value in the second target SIP signaling, the IMS of the terrestrial communication network determines the terminal location information in the second target SIP signaling, and supplements the called number based on the terminal location information and the base station location information of the terrestrial communication network.

[0089] Specifically, if it is identified that the second parameter in the second target SIP signaling is the second preset value, it means that the access location simulation has not yet been performed in the satellite mobile network, and the IMS of the ground communication network is required to determine the terminal location information in the second target SIP signaling, and perform access location simulation based on the terminal location information and the base station location information of the ground communication network, and supplement the called number.

[0090] In an embodiment of the present invention, the IMS of the terrestrial communication network determines the terminal location information in the second target SIP signaling, and supplements the called number based on the terminal location information and the base station location information of the terrestrial communication network, including: in the IMS of the terrestrial communication network, the second call session control component identifies the second preset value in the second target SIP signaling; when the second preset value is identified, the second call session control component sends the second target SIP signaling to the second dedicated server; the second dedicated server determines the terminal location information in the second target SIP signaling, and determines the simulated base station based on the base station location information and the terminal location information; the second dedicated server supplements the country code and / or area code of the called number based on the base station location information of the simulated base station.

[0091] In this embodiment, the second call session control component refers to the CSCF in the IMS of the communication network, which can identify the P-Access-Network-Info header field in the second target SIP signaling and check the S-access-location parameter therein. If S-access-location = No, it means that the simulated access location information processing has not been performed. At this time, the CSCF sends the signaling to the second dedicated server, that is, a dedicated application server (AS) in the IMS of the ground communication network.

[0092] The second dedicated server compares the location information of the terminal (including country, city, longitude and latitude) with the signal coverage of the ground mobile base station. If the terminal is located within the coverage of a cellular mobile communication base station, the base station closest to the terminal is selected as the simulated base station. If the terminal is not located within the coverage of any base station, or the AS does not have sufficient data or judgment capabilities, the default location area code (LAC) and cell identity (CI) are used.

[0093] Furthermore, the S-LAC (simulated location area code) and S-CI (simulated cell identification code) parameters are added to the P-Access-Network-Info header field, and the values ​​are assigned to the simulated base station or the default LAC and CI. Finally, the call is regarded as a call from the simulated base station, and the called number is supplemented. If the called number is a fixed number, the supplemented format is: country code + area code + user number. If the called number is an emergency number, the supplemented format is: country code + area code + emergency number (including a prefix or suffix to distinguish the specific service station). The supplemented called number is written into the SIP call signaling. The value of the S-access-location parameter in the P-Access-Network-Info header field is set to Yes, indicating that the simulated access location information processing has been completed.

[0094] S260. The IMS of the terrestrial communication network adds the supplemented called number to the second target SIP signaling to obtain a third target SIP signaling.

[0095] Specifically, the second dedicated server transmits the third target SIP signaling obtained after processing to the CSCF of the terrestrial communication network.

[0096] S270. The IMS of the terrestrial communication network executes a call flow of the called number based on the third target SIP signaling.

[0097] The CSCF of the terrestrial communication network receives the third target SIP signaling and checks if S-access-location=Yes in the P-Access-Ne twork-Info header field. If yes, the CSCF regards the caller initiated from the satellite communication network as a caller initiated from the simulated base station and processes the subsequent call flow accordingly.

[0098] In the technical solution of the embodiment of the present invention, calls between the satellite mobile network and the terrestrial communication network are realized by simulating the access location information, so that when the user uses the satellite mobile phone to call the terrestrial communication network (such as calling a fixed phone and an emergency call), the dialing habit is the same as that of the terrestrial network, and there is no need to add an area code. Since the location information of the terminal is added to the call issued by the satellite communication terminal, the call is simulated as a call issued from the terrestrial base station according to the corresponding relationship between the location and the coverage range of the terrestrial base station. Therefore, some services provided according to the access location can also be realized, such as determining the user's roaming in and out of a certain area according to the location information.

[0099] At the same time, considering that the satellite communication network may not have simulation capabilities due to the lack of data such as the location and coverage of ground base stations, the present invention supports first completing the simulation in the satellite communication core network, and if it cannot be completed, the simulation can be further completed in the ground communication network. That is, in the process of interconnection and intercommunication, both parties cooperate to complete the simulation processing, thereby improving the reliability of the access location simulation.
