Problems solved by technology

And if the HSS is down or the network between I-CSCF and HSS is abnormal, the IMS will fail to process the call request initiated by the user
The typical problem of this defect is that I-CSCF querying the called number has a strong dependence on HSS, and message exchange will increase additional network traffic and will terminate the call in abnormal scenarios

Embodiment Construction

[0064] The basic idea of ​​the present invention is: store the association relationship between the registration number and the CSCF to which the registration number belongs in the I-CSCF, and query the called number in the storage area of ​​the I-CSCF when the I-CSCF receives a session request The belonging CSCF is enough, and forwards the call request to the CSCF belonging to the queried called number to realize session access.

[0065] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following examples are given and the accompanying drawings are given to further describe the present invention in detail.

[0066] image 3 It is a flowchart of the process of registering and caching data in the embodiment of the present invention, image 3 , describes the process of I-CSCF caching the associated data between the registration number and the CSCF to which the registration number belongs during the user registration proces...

Abstract

The invention discloses a method and a device for session access as well as an interrogating call session control function. The interrogating call session control function (I-CSCF) stores incidence relations between registration numbers and call session control functions (CSCFs) to which registration numbers belong. The method comprises that when the I-CSCF receives a session request, the CSCF to which the called number belongs is inquired in a storage area of the I-CSCF, and a call request is forwarded to the inquired CSCF to which the called number belongs, so that session access is achieved. By the aid of the method and the device, information interaction between the I-CSCF and a home subscriber server (HSS) can be reduced effectively, the network flow is reduced, the access rate of sessions is accelerated, the session access can also be achieved even if the HSS fails or a network between the I-CSCF and the HSS fails, and the access success rate of session processes is greatly increased.

Description

technical field [0001] The present invention relates to session access technology, in particular to a session access method and device. Background technique [0002] IP Multimedia Subsystem (IMS, IP Multimedia Core Network Subsystem) is a next-generation network standard defined by the Third Generation Partnership Organization (3GPP, 3rd Generation Partnership Project). Protocol) system, its communication has nothing to do with access, it has multiple capabilities such as separation of multimedia service control function and carrying capacity, separation of call and service, separation of application and service, separation of service and network, and integration of mobile network and Internet services. [0003] The main functional entities in IMS include call session control entity (CSCF, Call Session Control Function) which controls user registration, session control and other functions, proxy call session control entity (Proxy-CSCF, referred to as P-CSCF), query call sess...
