Description

Speech business processing method, system and the device of a kind of CDMA under LTE evolution

Technical field

The present invention relates to moving communicating field, relate in particular to speech business processing method, system and the device of a kind of CDMA under LTE evolution.

Background technology

(Long Term Evolution, LTE) network improves and has strengthened third generation partner program (Third Generation Partnership Project, aerial access technology 3GPP) Long Term Evolution.Under the non-roaming situation network architecture of LTE as shown in Figure 1, wherein, evolution base station is responsible for modulation, channel coding/decoding, Radio Resource control, wireless mobility management of data etc.; Gateway and packet data network gateway are the gateways after the evolution, are responsible for transmitting packet; (Mobility Management Entity MME) is the signaling controlled entity of LTE system to Mobility Management Entity, is responsible for functions such as authentication, mobile management.Network after the evolution does not provide the phonetic function of legacy circuit-switched, and the high data rate bearer service only is provided.

(Code Division Multiple Access, CDMA) operator generally can dispose LTE at hot zones earlier to the 3GPP2 code division multiple access, and then enlarges the deployment scope gradually.Because existing CDMA single carrier Radio Transmission Technology (Single Carrier Radio Transmission Technology, 1xRTT, being called for short 1x) network coverage is very big, and the LTE network that hot zones is disposed is equivalent to be added on the CDMA 1x network, as shown in Figure 2.CDMA operator after disposing the LTE network, speech business provide following dual mode:

First kind be called circuit domain dropping (Circuit Switched Fallback, CSFB).This mode has been introduced 1x circuit domain dropping interoperability solution functional entity (1x Circuit Switched Fallback Interworking Solution Function, 1xCS IWS), and the network architecture as shown in Figure 3.1xCS IWS provides the A1 interface and (the Mobile Switching Center of 1x mobile switching centre of standard, MSC) link to each other, provide the S102 interface to link to each other with MME, be used for by LTE/ System Architecture Evolution (System Architecture Evolution, SAE) Network Transmission CDMA 1x message realizes that CDMA 1x circuit domain pre-registration, called voice paging and the short message when terminal resides in the LTE network sends; When terminal need be initiated or receive speech business, turn back to CDMA 1x network, the circuit domain by CDMA 1x network (as, MSC is the service equipment of circuit domain) speech business is provided.

Because CSFB need use existing C DMA 1x network that speech business is provided, and causes CDMA 1x network can not progressively discharge employed radio frequency resources, is unfavorable for the speech of CDMA to LTE.And subscriber equipment (User Equipment, UE) fall back to CDMA 1x after, the data service of activation need be suspended or switch to high-speed grouped data system (when supporting voice simultaneously and D0), causes data service to be experienced and reduces.And this framework does not make full use of the powerful IP-based voice of LTE (Voice over Internet Protocol, VoIP) tenability yet.

Second kind is VoIP, need to dispose IP Multimedia System (IP Multimedia Subsystem, IMS) finish speech business control, (Policy and Charging Control, PCC) framework guarantees the service quality of VoIP at the LTE/SAE network to use 3GPP strategy and charging control.After IMS finishes the quality of service requirement of conversation initialized protocol/Session Description Protocol acquisition VoIP, by Rx interface notification strategy and charging regulation function entity (Policy and Charging Rules Functions, PCRF), set up the dedicated bearer that satisfies quality of service requirement by PCRF notification service gateway/packet data network gateway at the LTE/SAE network, be used for guaranteeing the service quality of VoIP.After moving out the LTE area of coverage, use UE injection frequency continuous voice call to finish the switching of VoIP to the 1xCS voice.Its network architecture as shown in Figure 4.Because IMS does not introduce other valuable new business with respect to CDMA 1x circuit domain core net, so it is not urgent to dispose IMS, also increased the networking cost simultaneously, be unfavorable for the investment protection.
