Mixed connection method for base station and core network

Abstract

The invention relates to a mixed connecting method of a base station and a core network, wherein, the core network is an IP network (1). The MSCe and the BSC are only connected by an IP method; MGW and the BSC are physically connected simultaneously by a TDM circuit of an A2 port and the IP method of an A2p port. The MSCe adopts a default control strategy to selectively perform a circuit bearing in the physical connection. By using the method, BSC are physically connected with MGW in two ways through different ports, and is connected with the MSCe in a unified IP way, by combining the circuitbearing and the load sharing of the physical connection of the control strategy, the original TDM circuit investment of an operator is maximally protected, the newly built IP is used for transmittingas possible, the existing resources can be fully utilized, the cost of the operator is lowered, thereby realizing various characteristic services, and protecting the interests of the operator at the highest degree, and at the same time, enriching the network construction modes and better achieving the smoothed transition of the network..

Description

technical field [0001] The invention relates to a mobile communication network, in particular to a method for forming a base station and a core network in a CDMA2000 network. Background technique [0002] CDMA2000 technology has achieved great success in the field of mobile communications. Global CDMA2000 commercial networks are becoming more and more common, and the number of CDMA users is also increasing. The development trend of CDMA2000 network is developing towards ALL-IP, following the softswitch idea of ​​separation of access layer, transport layer, call control layer and service layer, each network layer evolves independently. [0003] The evolution steps of CDMA2000 network to ALL-IP are divided into Phase0, Phase1, Phase2 and Phase3. Phase 0 and Phase 1 are based on traditional circuit-based wireless networks, supporting circuit switching technology and initial packet switching technology. Phase 2 is also called the traditional MS domain LMSD phase. In this phase,...

Problems solved by technology

[0005] In the current technology evolution process, the CDMA2000 core network equipment MSCe / MGW can simultaneously access the BSC carrying TDM or BSC carrying IP, which can realize the smooth transition of the network from TDM to IP upgrade, but between MSCe / MGW and There is currently no such solution for the coexistence of TDM bearer and IP bearer between the same BSC, which cannot meet the needs of operators to maximize the use of existing network and transmission resources to achieve various special services when performing smooth upgrades.
