Problems solved by technology

[0003] Moreover, in the dormant handover between ANs and PCFs provided by the current HRPD standard, the PPP connection in use needs to be released during the handover process, and the PDSN needs to allocate a new PPP connection for the target network. On the one hand, the newly allocated PPP connection may be due to Due to resource problems and other reasons, the allocation fails and the user's business is interrupted. On the other hand, because the PDSN needs to re-establish a PPP connection, it will cause a relatively large delay in the user's current business.

Embodiment Construction

[0074] The method of the present invention is applied in the process of AT moving from the source AN to the target AN, and the AT and the source AN, PCF and PDSN are in active state data service. The method of the present invention can be divided into two situations, one is that the AT switches between ANs, and the target AN and the source AN belong to the same PCF; the other is that the AT switches between ANs, but the target AN and the source AN belong to the same PCF; The PCF is not the same case.

[0075] For the first case, when the target AN receives the handover request message sent by the AT, it obtains the session layer information related to the AT from the source AN, and establishes A8 and A9 links with the PCF according to the session layer information ; Then, the target AN sends the traffic channel information to the source AN, the source AN stops the A9 link transmission with the PCF, and sends the traffic channel information to the AT, and the AT uses the traffi...

Abstract

This invention discloses a method for realizing activated state hard switch in a high speed packet data system including: after target AN receives the switch request information sent by AT, it gets the session layer information from the source AN related to AT to set up A8 and A9 links with PCF based on the session layer information , target AN sends the service channel information assigned to AT to source AN, which releases link A9 and sends said service channel information to the AT setting up service channel connection with target AN, which assigns an exclusive UATI for AT and sends the UATI to AT, target AN activates link A9, AT sets up PPP service link via target AN and activates packet data connection by target AN.

Description

technical field [0001] The invention relates to the technical field of switching in a high-speed packet data (HRPD) system, in particular to a method for realizing hard switching in an active state in the HRPD system. Background technique [0002] After the HRPD network air interface standard was upgraded from version 0 to version A, many system features have been enhanced, such as system capacity, quality of service (QoS), etc. These improvements make the HRPD network need to support packets with higher speed and higher real-time requirements business. In this standard, the handover process defines the dormant handover between the access network (AN) and the AN, the dormant handover between the packet control function (PCF) and the PCF, the origination and release process of each call, and HRPD network and cdma2000 network. Various switching processes between. However, there is no definition for the hard handover process in the active state within the HRPD network. In or...
