Abstract

The invention discloses a calling method, device and system, and relates to the field of mobile communication. The method comprises the following steps: an IMS user location information platform receives an access administrative region identifier acquisition request carrying terminal location information sent by a terminal; the IMS user position information platform determines an access administrative region identifier corresponding to the terminal according to a corresponding relation between the terminal position information and the access administrative region identifier, and sends the access administrative region identifier to the terminal; and the P-CSCF / BAC device receives a call request which is sent by the terminal and carries the access administrative region identifier, and executes a call service according to the call request. According to the invention, the IMS user position information platform is introduced at the network side, and the matching query capability based on the user calling position and the corresponding access administrative region identifier is established at the IMS user position information platform, so that the burden of the P-CSCF / BAC equipment is reduced, and the probability of performance deterioration of the P-CSCF / BAC equipment is reduced.

Description

technical field [0001] The present disclosure relates to the field of mobile communications, in particular to a calling method, device and system. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), is a brand-new multimedia service form, which can meet the needs of more novel and more diversified multimedia services of current terminal customers. Compared with the softswitch solution, the IMS solution has many advantages, and is playing an increasingly important role in the NGN (Next Generation Network, next-generation network) market. International authoritative standard organizations generally regard IMS as the core standard for NGN network integration and service and technology innovation. IMS can not only realize the original VoIP service, but more importantly, IMS will manage network resources, user resources and application resources more effectively, improve the intelligence of the network, and enable users to use various terminals ...
