Method for realizing two-directional interacting of circuit zone and grouping zone, and system therefor

Abstract

Being applicable to system of containing network in circuit domain and network in packet domain, the disclosed system includes interoperation gateway. Being connected to network in circuit domain and network in packet domain, the said interoperation gateway possesses functions: in use for storing information of network the terminal in dual mode locates at, and calling state; based on the said information, forward shifting the said information of network in circuit domain to network in packet domain; or through network in packet domain, informing the terminal in dual mode that there are system message or paging message in circuit domain; or forward shifting the said information in network in packet domain through calling to network in circuit domain; or through network in circuit domain, informing the terminal in dual mode that there are said information in packet domain. The invention also discloses method for terminals in packet domain to implement service in circuit domain.

Description

technical field [0001] The present invention relates to the technical field of cdma2000 systems, in particular to a method and system for realizing two-way interoperability between the circuit domain and the packet domain in the cdma2000 system. Realizing the two-way interoperability between the circuit domain and the packet domain means that a terminal residing in the circuit domain can Receive packet domain services, and terminals residing in the packet domain can receive circuit domain services. Background technique [0002] In a dma20001x network, if a mobile terminal (MS) performs services in the PS domain, there may be system messages or paging messages for the MS in the CS domain network. Conversely, if the MS is in the CS domain, there may also be packet service flows that need to be delivered. to MS. However, in the above network framework, when the mobile terminal performs services in the packet domain, it cannot monitor system messages and paging messages in the ...

AI Technical Summary

Problems solved by technology

However, in the above-mentioned network framework, when the mobile terminal conducts business in the packet domain, it cannot monitor the system messages and paging messages of the circuit domain.

When the user is in the circuit domain for business, but can not listen to the system message and paging message of the packet domain network

Therefore, users may miss out on packet domain traffic due to the inability to listen

[0003] Of course, in order to achieve interoperability, the cross paging model and the improved cross paging model have been proposed successively. For example, in the improved cross paging model, the IWS function (Functin) is further added to the MSC, and the It is possible to enable mobile terminals in the activated state in the PS domain to receive system messages and paging messages in the CS domain, but it is not possible to enable terminals in the CS domain to perform PS domain services, and this method also requires the existing access network Improvements to the circuit domain network are also complicated to implement, which is not conducive to the needs of low-cost networking

There is also the problem that DO and 1x need to be planned together, which greatly increases the difficulty of planning
