Embodiment Construction

[0047] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0048] A method for keeping the reverse logical channel consistent provided by the present invention, such as figure 1 As shown, it mainly includes the following steps:

[0049] Step 101 , when the AT performs handover between ANs, the source AN sends to the target AN the correspondence between the reverse channel allocated for the AT and the reverse logical channel.

[0050] The inter-AN handover of the present invention is the inter-AN handover of Session control right conversion, typically can be A16 handover and A13 handover, certainly the inter-AN handover of the present invention is not only limited to A16 handover and A13 handover, for other Session control right Converted inter-AN handovers are also applicable.

[0051] In the air interface standard protocol, the session state message (Session State Info) i...

Abstract

The invention discloses a method for keeping a reverse logic channel consistent, comprising the following steps of: transmitting a corresponding relationship of a reverse channel allocated for an AN (Access Network) and the reverse logic channel to a target AN by a source AN when an access terminal (AT) accesses among ANs and allocating a corresponding reverse logic channel for a newly-added reverse channel according to the corresponding relationship of the received reverse channel and the reverse logic channel when the newly-added reverse channel exists in the target AN. The invention also discloses a system for keeping the reverse logic channel consistent, which ensures that information of the reverse logic channel in the target AN keeps consistent with that of the source AN during AN switch, thereby ensuring that the reverse logic channel allocated by the target AN for newly-added reverse channel cannot be conflicted with the allocated reverse logic channel.

Description

technical field [0001] The present invention relates to handover technology in wireless communication, in particular to a method and system for keeping a reverse logical channel (ReverseLogicalChannel) consistent. Background technique [0002] In the Multicarrier Reverse Traffic Channel Media Access Control (MCRTCMAC, Multicarrier Reverse Traffic Channel Media Access Control) protocol of the current code division multiple access packet data service evolution standard (CDMA 1X EV-DO) air interface version, the reverse traffic is defined A channel confirmation (RTCAck, Reverse Traffic Channel Acknowledgment) message is used to notify the access terminal (AT, Access Terminal) that the access network (AN, Access Network) has captured one or more reverse channels; after the AT receives the RTCAck message, Service data can then be sent on the indicated reverse channel. The definition of RTCAck message is shown in the following table: [0003] field Length (bits) ...
