CDMA (Code Division Multiple Access) business nested method and system based on IMS (IP Multimedia Subsystem) network

Abstract

The invention discloses a CDMA (Code Division Multiple Access) business nested method and system based on an IMS (IP Multimedia Subsystem) network. The CDMA business nested method comprises the following steps: a core network of a C-network obtains information signed by users signed in the C-network and triggers calls to an anchoring business platform according to the signed information; the anchoring business platform caches calling party numbers and called party numbers of the calls and distributes temporary local numbers for the calls; the core network routes the calls to an MGCF (Media Gateway Control Function) module of the IMS network of a user attribution place according to the temporary local numbers; the MGCF module obtains the called numbers of the calls from the anchoring business platform and routes the calls to a S-CSCF (Serving-Call Session Control Function) module; the S-CSCF module sequentially triggers the calls to corresponding business platforms according to iFC (Initial Filter Criteria) information signed by the users in the IMS network and a priority order; and after the business platforms process the calls, the business platforms route the calls to a target network or interacts with the MGCF so as to land the calls. According to the CDMA business nested method, the coming and going calls of the C-network user can be routed to the IMS network so as to realize the nested triggering of multiple services.

Description

technical field [0001] The present invention relates to an IP multimedia subsystem, in particular to an IMS network-based CDMA service nesting method and system. Background technique [0002] Code Division Multiple Access (CDMA) is a new and mature wireless communication technology developed on spread spectrum communication technology, a branch of digital technology. The CDMA network is divided into three phases, namely IS-95, CDMA One and CDMA2000. The technical advantages of CDMA network are: simple wireless network planning, high frequency reuse coefficient; good concealment and high confidentiality; unique soft handover technology is used to reduce the drop rate; mobile phone transmission power is low and radiation is small. [0003] However, under the existing CDMA network technology system, the CDMA user can only be set on the HLR to trigger the service to an intelligent network service platform (that is, only to trigger the service to a global code (GT) address), so ...

Problems solved by technology

[0003] However, under the existing CDMA network technology system, a CDMA user can only be set on the HLR to trigger the service to an intelligent network service platform (that is, only to trigger the service to a global code (GT) address), so if the CDMA There are multiple intelligent service platforms on the network that provide multiple services respectively, and users will not be able to trigger multiple services at the same time, so they cannot use multiple services at the same time
