CDMA20001x has been because the technology comparative maturity has obtained using comparatively widely at present, and network coverage is wide, and HRPD is in the evolution, below CDMA20001x is called for short 1x.In order to allow the user can enjoy the business of two networks in the zone that two net stacks cover, have mode mobile terminal at present, the interoperability of HRPD network and 1x network has also been proposed on standard simultaneously.In order to realize the interoperability of HRPD network and 1x network, cross-paging (Cross-paging) technology has been proposed in the standard, can receive the paging of other networks when promptly portable terminal resides in a network, the user then can select whether to answer new calling.In order to realize cross-paging, at the A1/A1P interface that has increased on the basis of original HRPD IOS standard between HRPD Access Network/Packet Control Function (AN/PCF) and the mobile switching centre (MSC/MSCe), terminal is carried out location registers by the A1/A1P interface to MSC/MSCe by AN after being linked into the HRPD network, and MSC just knows which AN/PCF is terminal be positioned at like this.
When the service paging of HRPD network need be issued to terminal by the 1x network, AN/PCF then will ask MSC/MSCe, and MSC/MSCe is issued to terminal with this paging by the 1x network; Equally, when the paging of 1x network need be issued to terminal by the HRPD network, MSC/MSCe was given to the HRPD network with the 1x paging, used (CSNA) agreement by AN/PCF by the circuit domain business notice and was issued to terminal.The prerequisite that realizes above function is that terminal is not left the MSC/MSCe that it carries out location registers.
Also be that cross-paging in the present standard has solved the following time of covering that terminal is in the MSC that its session place AN/PCF connects, the problem that the HRPD ICQ issues by the 1x network.
But also there is such situation in actual applications, as shown in Figure 1, when the switching of MSC has taken place to stride when the 1x network carries out business terminal, terminal moves to position B from position A as shown in Figure 1, promptly moved to the coverage of MSC2 from the coverage of MSC1, perhaps terminal is when position B initiates the 1x business, and the service MSC at terminal place is MSC2.Because terminal is when carrying out the 1x Network, can not monitor the HRPD network, the HRPD network can't be known the reposition of terminal, if the calling that come the HRPD network this moment, then source AN/PCF will go to transmit paging by source MSC, and source AN/PCF is (AN/PCF) 1 among Fig. 1, source MSC is MSC1, and since at this moment terminal switched to new MSC, be MSC2 among Fig. 1, so the paging of source MSC will be failed.
