Description

Implementation method of application data delivery service and interoperability solution function body

technical field

The present invention relates to the communication field, and in particular to a method for realizing CDMA20001x application data delivery service and an interoperability solution function body (IWS) under the interoperability between CDMA20001xRTT (Radio Transmission Technology) and other access technologies.

With the evolution from the CDMA (Code-Division Multiple Access, Code Division Multiple Access) network to the LTE (Long Term Evolution, Long Term Evolution) network, services will gradually be carried by the LTE network. In the initial stage of LTE network construction, the main purpose is to cover hotspot areas and provide high-speed non-real-time data services. Voice services are still carried by 1xCS (circuit domain), and application data delivery services (such as short messages, etc.) and registration services will pass through Therefore, the interoperability between CDMA2000 1x and LTE is mainly reflected in the support of 1xCSFB (1xCircuitServiceFallBack, 1xCircuitServiceFallBack, 1xCircuitServiceFallBack), including voice services, registration, and application data delivery services (such as short messages, air parameter management, and air business provision, etc.). At the same time, the implementation method of CDMA20001x and LTE interoperability can also be considered to be applied to the interoperation of CDMA20001x and High Speed Packet Data (HRPD) network.

The network architecture of 1xCSFB is shown in Figure 1. One of the logical functions of IWS (Inter-workingSolution, interoperability solution function body) is to serve as a CDMA1x message forwarder and processor, that is, the terminal sends messages to the 1x system through LTE and the 1x system passes through The messages sent by LTE to the terminal need to be forwarded by IWS.

As a logical function body, IWS can be implemented in 1xBSC (BaseStationController, base station controller), or in MSC (MobileSwitchingCenter, mobile switching center), or in MME (MobilityManagementEntity, mobility management entity) of LTE network. Can be an independent network entity.
