Embodiment 1

[0082] Fig. 5 is a flowchart of Embodiment 1 of the present invention. Referring to Fig. 2 and Fig. 5, when utilizing the first structure of the system of the present invention shown in Fig. 2, the process of the inventive method realizing that the session in the CDMA1x network is handed over to the HRPD network comprises the following steps:

[0083] Step 501: When the dual-mode terminal conducts a session in the CDMA1x network, the base station in the CDMA1x network detects a handover triggering event.

[0084] Here, when the dual-mode terminal conducts a session in the CDMA1x network, the dual-mode terminal may actively send a handover request to the base station. At this time, in this step, the base station monitoring the handover trigger event includes: the base station receives a The switch request sent by the terminal.

[0085] In this step, the handover triggering event detected by the base station may also be: the base station detects that the wireless signal quality...

Embodiment 2

[0106] Fig. 6 is a flowchart of Embodiment 2 of the present invention. Referring to Fig. 3 and Fig. 6, when utilizing the second structure of the system of the present invention, the process of the inventive method realizing that the session in the CDMA1x network is handed over to the HRPD network comprises the following steps:

[0107] All descriptions of steps 601 to 602 are the same as those of steps 501 to 502.

[0108] Step 603: The base station in the CDMA1x network sends a handover request carrying the dual-mode terminal ID and the determined AN ID to the Mobile Switching Center (MSC) through the A1 interface.

[0109] Step 604: According to the AN identifier in the received handover request, the mobile switching center sends the handover request carrying the dual-mode terminal identifier to the AN through the A1p interface.

[0110] In this step, when the AN receives the handover request, it can further authenticate the dual-mode terminal according to the identity of ...

Embodiment 3

[0117] Fig. 7 is a flowchart of Embodiment 3 of the present invention. Referring to Fig. 4 and Fig. 7, when utilizing the third structure of the system of the present invention, the process of the inventive method realizing that the session in the CDMA1x network is handed over to the HRPD network comprises the following steps:

[0118] All descriptions of steps 701 to 702 are the same as those of steps 501 to 502.

[0119] Step 703: The base station in the CDMA1x network sends a handover request carrying the dual-mode terminal ID and the determined AN ID to the mobile switching center through the A1 interface.

[0120] Step 704: After receiving the handover request carrying the ID of the dual-mode terminal and the ID of the selected AN, the mobile switching center sends the handover request to the IWS entity through the A1p interface.

[0121] Step 705: After receiving the handover request, the IWS entity sends the handover request carrying the dual-mode terminal identity to ...

Abstract

The invention discloses a method for switching all to high-speed group data (HRPD)network, and a relative system, wherein the method comprises that when a multimode terminal processes call in a non-HRPD network, the base station in the non-HRPD network sends a switch request carrying a multimode terminal mark to an access network deice AN in the HRPD network, AN receives the switch request, to build a data chain connection in the HRPD network, the multimode terminal via the built data chain connection processes the call continuously in the HRPD network. The invention builds a data chain load in HRPD network when multimode terminal processes call in non-HRPD network, to reduce switch time delay, avoid conversation interruption of multimode terminal, and confirm communication continuity.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and system for switching a session of a non-high-speed packet data (HRPD) network to an HRPD network. Background technique [0002] Both CDMA2000 and HRPD belong to the series of CDMA technical standards. Among them, the CDMA2000 system is used for basic coverage, providing users with voice services and low-speed packet data services; HRPD network, as a supplement to the CDMA2000 system, is used for hotspot coverage and usually provides users with high-speed packet data services. [0003] At present, in order to expand the application of the HRPD network, various implementation schemes for providing voice services in the HRPD network in the form of VOIP have been proposed. In this way, the voice service can also be realized in the HRPD network. In addition, at present, a dual-mode terminal having the function of a terminal (MS) in the CDMA2000 system and a terminal (A...
