technical field

Under the IMS network, users can subscribe to multiple IMS services, and trigger and use IMS services in the registered IMS network. In the prior art, a user accesses the IMS network through a certain access network, and the IMS network judges whether the user's access network is a network limited by the IMS network. If it is a network limited by the IMS network, when the user requests a service from the IMS network, HSS (Home Subscriber Server, home user server) sends the iFC (Initial Filter Criteria, initial filter rule) in the subscription data to S-CSCF (Serving Call Session Control Function, serving call session control function), and S-CSCF receives the SIP ( Session Initiation Protocol (Session Initiation Protocol) request, using SIP request and iFC for matching detection, when the service trigger condition of iFC is met, the AS (Application Server, application server) corresponding to the trigger condition is triggered.

The IMS network often restricts the actual access network of the user. When the IMS network finds that the access network of the subscribed service of the requested user is not the access network restricted by the IMS network, the IMS network will reject the registration of the user on the IMS network. As a result, all the subscribed IMS services of the user cannot be used. In the prior art, all subscribed IMS services of a user are triggered in one access network scenario. However, due to different network performances such as bandwidth and delay of different access networks, different IMS services are applicable to different access network scenarios, and in the prior art, for the same user, there is no Different service servers are triggered to realize the method of using different IMS services in different access network scenarios.

101. The SBC network element/P-CSCF network element acquires first network registration information of a user and access network information of the user.

Wherein, the first network registration information includes at least the user's IMPI (IP Multimedia Private Identity, Internet Protocol Multimedia Private Identity) and IMPU (IP Multimedia Public Identity, Internet Protocol Multimedia Public Identity). The first network registration information may also include home network domain name, session description information, etc., which is not limited here.

network location information pppoe-username (point-to-point connection-username) wlan-ssid (Wireless LAN-Service Set Identifier) epdg-id (packet data gateway-identification) cell-id (cell-identification) other information etc.

Table II

Among them, the network type information is used to identify the network type. As shown in Table 1, the network type can be various wireless local area networks, such as: home wireless local area network, trusted or untrusted wireless network; it can also be GSM/EDGE (Global System For Mobile Communication/Enhanced Data Rate for GSM Evolution, Global System for Mobile Communications/Enhanced Data Rate GSM Evolution Technology) radio access network, that is, 2G network; it can also be UMTS (Universal Mobile Telecommunications System, which means Universal Mobile Communications System) land The radio access network is a 3G network; it may also be an evolved UMTS terrestrial radio access network, namely a 4G network, and other types of networks.

As shown in Table 2, the network location information may be a connection user name, service set identifier, cell identifier or gateway identifier, etc. Here, the specific representation of the network location information is not limited.

Among them, the network type information and network location information can identify a specific network that the user accesses. For example, if the network type information is 3gpp-wlan-trust and the network location information is "user123", it means that the network that the user accesses is a network named Trusted WLAN for "user123".

102. The SBC network element/P-CSCF network element uses the first network registration information and the access network information to generate second network registration information, and sends the second network registration information to the I - CSCF network element.

Wherein, the second network registration information includes IMPI, IMPU and access network information. The SBC network element/P-CSCF network element may add the network type information and the network location information to the first network registration information, so as to generate the second network registration information. The SBC network element/P-CSCF network element can also extract the information required in the subsequent process from the first network registration information, such as IMPI, IMPU, etc., and recombine with the network type information and network location information to generate the second network registration information. When the second network registration information generated by the SBC network element/P-CSCF network element contains other information such as IMPI and IMPU, the HSS network element in the IMS is required to be able to identify other information such as IMPI and IMPU, so as to facilitate subsequent processes. Recognition processing.

103. The I-CSCF network element generates user authorization request UAR information according to the second network registration information, and sends the UAR information to the HSS network element.

Wherein, the UAR information includes IMPI, IMPU, and access network information. In a specific implementation, the I-CSCF network element can obtain information such as IMPI, IMPU, and access network information from the second network registration information, and use the information such as IMPI, IMPU, and access network information to generate a UAR (User Authorization Request, User authorization request) information, and send the UAR information to the HSS network element. The access network information may be network type information and network location information.

104. The HSS network element determines a target initial filtering rule in initial filtering rules by using the access network information in the UAR information.

Among them, the HSS network element stores the initial filtering rules in all access scenarios. The initial filtering rules carry network applicable information, and the network applicable information is used to indicate the access network targeted by the initial filtering rules. The network applicable information can be network type information and The network location information may also be other identification information capable of identifying the network type and network location, such as numbers and character strings.

It should be noted that the HSS network element can identify the UAR information including IMPI, IMPU, and access network information, and use the access network information in the received UAR information to create initial In the filtering rule, the target initial filtering rule corresponding to the network type information and the network location information in the UAR information is determined. For example, there are three initial filtering rules stored in the HSS network element, which are IFC1, IFC2, and IFC3. IFC1 is the initial filtering rule corresponding to voice service A. Voice service A carries network applicable information, indicating that voice service A is under the 2G network. It cannot be used, and it can only be used in the network with the cell id named "abc" in the 3G network; IFC2 is the initial filtering rule corresponding to the instant message service B, and the instant message service B carries network applicable information, indicating that the instant message service B is in It can be used under any network; IFC3 is the initial filtering rule corresponding to video service C, and video service C carries network applicable information, indicating that video service C can only be used under the home wireless LAN whose service set identifier is "user1"; The incoming network information includes network type information and network location information. The network type information obtained by the HSS network element from the URA information is 3G network, and the network location information is the cell id "abc", indicating that the user has accessed the cell id "abc". In the 3G network, the HSS network element determines IFC1 and IFC2 as the target initial filtering rules in IFC1, IFC2, and IFC3.

In specific implementation, the determined target initial filtering rules can be formed into a rule list in the access network scenario, one access network scenario corresponds to a rule list, and a rule list includes the target in the access network scenario The initial filtering rules, in different access network scenarios, facilitate the S-CSCF network element to download the rule list corresponding to the current access scenario from the HSS network element.

105. The HSS network element acquires the IMPI and the IMPU from the UAR information, authenticates the user according to the IMPI and the IMPU, and when the authentication passes, according to the IMPI and the IMPU The IMPU determines the S-CSCF network element corresponding to the user.

Wherein, IMPI and IMPU are used to identify the user. The HSS network element authenticates the user's identity and service authority according to the user's IMPI and IMPU.

It should be noted that different users may correspond to different S-CSCF network elements, so it is necessary to determine the S-CSCF network element serving the user. When the user authentication passes, the HSS network element determines the S-CSCF network element that can provide services for the user according to the IMPI and IMPU that can identify the user, and sends the second registration information to the S-CSCF network element corresponding to the user , so that the S-CSCF network element requests the HSS to download the target initial filtering rule in a subsequent process.

106. The S-CSCF network element downloads the target initial filtering rule from the HSS network element, obtains Session Initiation Protocol SIP information, matches the SIP information and the target initial filtering rule, and triggers a service server.

When the SIP information meets the trigger condition of the target initial filter rule, trigger corresponding business server.

In the specific implementation, the S-CSCF network element extracts SPT (Service Point Triggers, service trigger point) information from the SIP information, and matches the SPT information with the trigger rule defined in the target initial filter rule. When the match is successful, the trigger and The service server corresponding to the SPT information; when the matching fails, the service server corresponding to the SPT information is not triggered. For example: the triggering conditions of the initial filtering rules corresponding to voice service A, video service B, instant message service C, and multimedia conference service D are shown in Table 3:

Table three

For example: the trigger condition of the initial filtering rule corresponding to voice service A is "(Method="INVITE")AND(Line="m", context=".*audio.*")", when the S-CSCF network element receives For a SIP message, it will extract SPT information from it, check whether the SPT message is an INVITE message, check whether the content of the line field in the SPT message is m, and check whether the content of the context field in the SPT message includes the audio field. When the SPT message is an INVITE message , and the content of the line field in the SPT message is m, and the content of the context field in the SPT message includes the audio field, it is determined that the SIP message is a message of the voice service A, thereby triggering the corresponding voice service server.

It should be noted that after the S-CSCF network element downloads the target initial filtering rules from the HSS network element, the S-CSCF network element sends a response message to the I-CSCF network element, and the I-CSCF network element sends a response message to the SBC network element. The SBC network element sends a response message to the user through the gateway and other network facilities, indicating that the IMS network registration process of issuing the corresponding initial trigger rule in the access network scenario is completed.

If the access network is not restricted by IMS, the user’s registration on the IMS network will be rejected, and all IMS services signed by the user cannot be used; resulting in all services signed by the user can only be used in one access network scenario use below. Compared with the prior art, in the solution of the present invention, the step of the IMS network judging whether the network accessed by the user is an access network defined by the IMS is eliminated, and the HSS network element will use the access network information of the user to In the initial filtering rules, determine the target initial filtering rules, and the target initial filtering rules only include the initial filtering rules corresponding to the services permitted by the user's current access network scenario, thereby triggering the services corresponding to the user's IMS services in the current access network scenario The server implements the use of different IMS services in different access network scenarios.

However, in the prior art, the IMS network first needs to determine whether the network accessed by the user is an IMS-restricted access network. If it is an IMS-restricted access network, all IMS services owned by the user will be filtered according to the initial filtering in this access scenario. If the access network is not restricted by IMS, the user’s registration on the IMS network will be rejected, and all IMS services signed by the user cannot be used; resulting in all services signed by the user can only be used in one access network scenario use below. Compared with the prior art, in the solution of the present invention, the step of the IMS network judging whether the network accessed by the user is an access network defined by the IMS is eliminated, and the HSS network element will use the access network information of the user to In the initial filtering rules, determine the target initial filtering rules, and the target initial filtering rules only include the initial filtering rules corresponding to the services permitted by the user's current access network scenario, thereby triggering the services corresponding to the user's IMS services in the current access network scenario The server implements the use of different IMS services in different access network scenarios.
