Embodiment Construction

[0066] The core of the present invention is to add a new service signaling interface between the source AN and the target AN to realize the active state soft handover and session migration between AN; The base station sends the data to the terminal, and realizes the combined processing of the reverse service data at the source AN through this interface. The present invention also includes migrating the session of the terminal to the target AN through smooth session migration. Specifically, the session migration process can be selected when all active sets of the terminal belong to the target AN.

[0067] The specific processing process is: when the source AN determines that the pilot of the target AN needs to be added to the active set according to the route update message, it sends a handover request to the target AN, and the target AN establishes a service with the source AN after receiving the request message link and allocate air interface resources, and then the source AN...

Abstract

The present invention relates to a network active state AN soft switching and conversation migrant implementation method. Said invention mainly includes active state source access network AN determining request to make switching operation, source AN according to user terminal sent route updating message to make information interaction with target AN, and establishing communication linkage betweensource AN with target AN, including signaling and service connection; based established communication linkage to realize soft switching processing and conversational migration processing between sourceAN and target AN. Therefore said invention realizes active state soft switching between HRPD system AN and PCF, through conversation migration smoothing migration terminal session to target AN.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing soft handover and session migration between active ANs in the network. Background technique [0002] With the development of communication technology, in order to solve the bottleneck problem on the air interface in the CDMA system, 3GPP2 (the international standard organization of the third generation mobile communication) released the standard of HRPD (HRPD-HighRate Packet Data, high-speed packet data) network technology . Its main purpose is to improve the data transmission rate of the wireless interface. Compared with 153.6kbit / s of cdma20001x, HRPD technology can provide forward data rate up to 2.4Mbit / s. [0003] In the HRPD network, HRPD adopts a new modulation technology on the air interface and adds methods such as data rate control, scheduling optimization and time division multiplexing, which greatly improves the data transmission ...
