Fig. 1 shows the networking schematic diagram of CDMA1x technology and HRPD technology in the prior art, as shown in Figure 1, the terminal of carrying out with the CDMA1x technology in the CDMA1x network of networking is travelling carriage (MS, Mobile Station), the terminal of carrying out with the HRPD technology in the HRPD network of networking is access terminal (AT, Access Terminal).CDMA1x can provide language business and low-speed data service to MS, and the HRPD network can provide high-speed data service to AT.The HRPD network can use independently packet data serving node (PDSN, Packet Data Serving Node) access the Internet (Internet), also can be by inserting Internet with the shared PDSN of CDMA1x.If HRPD network and CDMA1x network home are in different operators, then HRPD network and CDMA1x network use PDSN separately to insert Internet; If HRPD network and CDMA1x network home are in same operator, then HRPD network and CDMA1x network can use PDSN separately to insert Internet, also can insert Internet by shared same PDSN, to reduce the operation cost of network.
Operator can extend the HRPD network usually on the CDMA1x network of having built, so that can provide high-speed data service to the user, at this moment, this operator runs CDMA1x and two networks of HRPD simultaneously.MS/AT among Fig. 1 a kind ofly can either insert the dual-mode terminal that the CDMA1x network can insert the HRPD network again, along with the progressively construction of HRPD network and perfect, uses the user of MS/AT to get more and more.
At third generation collaborative project tissue 2 (3GPP2, Third Generation Partnership Project 2) in the technical standard of Zhi Dinging, without any interface, only in the construction of real network, HRPD network and CDMA1x network can shared PDSN between HRPD network and the CDMA1x network.Shared PDSN only inserts the gateway device of Internet as the terminal in HRPD network and the CDMA1x network, be mainly used in loaded packet data, collecting charging information etc.For dual-mode terminal MS/AT,, should be able to answer audio call from the CDMA1x network if this dual-mode terminal resides in when carrying out high-speed data service in the HRPD network.
After MS/AT resides in the HRPD network, the state of three kinds of Packet data services is arranged, comprise empty state, dormant state and activated state.Under empty state, MS/AT can carry out location registers at HRPD network and CDMA1x network, only intercepts system message and beep-page message from HRPD network or CDMA1x network; Dormant state be meant MS/AT keep with the HRPD network between be connected, but do not carry out any transfer of data and do not use interface-free resources, this moment, MS/AT can intercept system message and the beep-page message from the CDMA1x network; Activated state is meant the state when MS/AT carries out high-speed packet data service in the HRPD network.
Because MS/AT resides in when carrying out high-speed data service in the HRPD network, should be able to answer audio call from the CDMA1x network, therefore, when MS/AT resides in when being in activated state in the HRPD network, each paging cycle need switch to the CDMA1x network to receive the beep-page message from the CDMA1x network, determined whether its beep-page message, can have a strong impact on even interrupt the real time high-speed Packet data service that MS/AT carries out like this in the HRPD network, as the speech business (VoIP) of IP carrying, video (Video) business etc.And, owing to when MS/AT is in activated state in the HRPD network, can't in the CDMA1x network, carry out location registers, if the position of MS/AT changes, then current location can't be registered to the CDMA1x network, make MS/AT can't receive beep-page message from the CDMA1x network.
