Problems solved by technology

[0006] For the MIP (Mobile IP) scenario, since the home network does not know whether the visited network has deployed an IMS network, the allocation of the corresponding SIP server needs to be undertaken by the home network; network, it is very likely that the HA and SIP server assigned to the user are in different networks, so that the communication signaling cannot be routed correctly, and the communication cannot be carried out normally.

Embodiment Construction

[0022] In the embodiment of the present invention, when the user accesses the visited network, the visited network sends the application server allocation information in the local network to the home network, and the application server allocation information is used to indicate whether the visited network has the ability to allocate application servers; so that The home network can determine the application server allocation policy for the user in the visited network according to the corresponding application server allocation information. The corresponding user may be one user terminal device, or one logical user (for example, multiple users corresponding to multiple different identification cards corresponding to one user terminal device, etc.), and so on.

[0023] Wherein, the corresponding application server allocation information includes at least one of an indication of whether it has the ability to allocate application servers and information about application servers al...

Abstract

The invention discloses a method, a device and a system for distributing application servers, which mainly comprises: a home network receives an application server distribution message sent by a visit network; the application server distribution message is used for indicating whether the visit network is capable of distributing application servers, so as to facilitate the home network to determine application server distribution strategy for the users in the visit network based on the application server distribution message. The invention embodiment gets the home network to learn the application server distribution capacity of the visit network, so as to determine the processing process of distributing the application servers to the users, thereby reliably distributing the corresponding application servers to the users and ensuring normal communication process.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, device and system for allocating application servers. Background technique [0002] In order to take advantage of the good scalability and low cost of the IP-based communication system, IMS (IP Multimedia Subsystem) was introduced into the 3GPP system to provide traditional circuit switching services and various multimedia services to users. [0003] When a user conducts business through the IMS network, P-CSCF (Proxy-Call Session Control Function, proxy-call session control function entity) is the first connection point for the user to communicate with the IMS network. Therefore, in access networks such as WiMAX (Worldwide Interoperability for Microwave Access) systems, SS (subscriber terminal) / MSS (mobile terminal) needs to know the IP address of at least one P-CSCF in order to communicate with the IMS network, so as to facilitate the SIP (Sessi...
