Problems solved by technology

This existing technology represents the intention of the caller by carrying some keywords, but the IMS network-related equipment cannot understand the meaning of these keywords, that is to say, the automatic discovery and invocation of services cannot be realized for users, resulting in the services that can be carried out The type and quantity are restricted by the number of keywords; in addition, different users may use different keywords, which is not conducive to large-scale application

no. 1 approach

[0037] refer to figure 2 , the present invention provides a first embodiment of a service network, including:

[0038] The terminal 210 includes a request unit 211, configured to send a SIP request message carrying service semantic information;

[0039] The session control function entity 220 includes a forwarding unit 221, configured to forward the SIP request message carrying the service semantic information from the request unit 211;

[0040] Service proxy server 230, including:

[0041] The matching unit 231 is configured to use the semantic information carried in the SIP request message received from the forwarding unit 221 as input, and search for the service through semantic reasoning;

[0042] The routing unit 232 is configured to generate a standard service request message, carry the service information found by the matching unit 231 in the service request message, and send it to the application server that processes the service.

[0043] It can be seen from the a...

no. 5 approach

[0064] refer to Figure 7 , the fifth embodiment of the network device of the present invention includes:

[0065] The request processing unit 711 is configured to extract the content of the request message received by the receiving unit 311 according to the defined extended SIP message syntax, and convert the extracted message into internal data.

[0066] A capability judging unit 712, configured to judge whether the network device is capable of processing the request after the receiving unit 311 receives the SIP request message carrying the service semantic information;

[0067] The forwarding unit 713 is configured to find a proxy server capable of processing the SIP request message in the service proxy server information database saved by the network device when the result determined by the capability judging unit 712 is no capability.

[0068] The request processing unit 711 of this embodiment can extract the requested message content according to the extended SIP messag...

no. 6 approach

[0076] refer to Figure 9 , the present invention also provides a sixth embodiment of the network device, including:

[0077] A detection unit 911, configured to receive a message, and detect whether the message is a SIP request message carrying business semantic information;

[0078] The forwarding unit 912 is configured to forward the SIP request message carrying the service semantic information to the service proxy server when the detection unit 911 detects that the message is a SIP request message.

[0079] The implementation of the network device can receive the SIP service request from the terminal, judge whether it is a SIP request carrying service semantic information, screen out such request and forward it to the service proxy server. The network device may be a CSCF, and the CSCF assists in implementing the routing selection function of the present invention.

[0080] refer to Figure 10 , the seventh embodiment of the network device of the present invention is si...

Abstract

The invention discloses a route selection method, a service network, a network equipment and terminal. The route selection method comprises: receiving SIP demand message carrying service semantic information; using the semantic information carried by the SIP demand message as input to search for said service by semantic reasoning; generating standard service demand message carrying the service information acquired by searching, and sending it to the application server for said service. The invention can increase the demandable service quantity and improve the service demanding flexibility.

Description

technical field [0001] The invention relates to the communication field, in particular to a route selection method, a service network, network equipment and a terminal. Background technique [0002] IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) is a new core network "domain" (Domain, a new mobile network system composed of many network elements) defined by 3GPP in UMTS R5 (and later versions). A prominent feature of IMS is that it uses a lot of Session Initiation Protocol (Session Initiation Protocol, SIP) to define the capabilities and interfaces of key network elements, and key network elements, such as a proxy call service control server (Proxy Call Server Control Function, P-CSCF ), querying the call service control server (Interrogating Call Server Control Function, I-CSCF), controlling the call service control server (Service Call Server Control Function, S-CSCF), etc., can be regarded as different types of SIP proxy / server. An application server (Application...
