Method, system and equipment for switching grouping switch in downward dual carrying / multi carrying transmission technique

Abstract

The invention discloses a switching method and system for an exchange in groups with a downlink double loading technique or a multi loading transmission technique, and a base station and a mobile station device, and mainly includes: a switching request message for switching over one carrier frequency is sent out to a switched target base station system BSS, when a need of a switch of over one carrier frequency for MS is ascertained by a resource network device where the mobile station MS is positioned; after the switching request message is received by the switched target base station system BSS, wireless resources of corresponding quantity of carrier frequencies are distributed to the current MS, and a replying message is returned to an origin BSS of the MS after the completion of the distribution; after the replying message is received by the origin BSS, a switching order including the distributed wireless resource information is sent out to the current MS; after the switching order is received by the current MS, a data transmission channel is off the carrier frequency of the origin BSS and is switched on over one carrier frequency distributed by the target BSS. The invention has the advantage that simple and reliable switching of PS is realized with the downlink double loading technique or the multi loading transmission technique.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a packet switching (PS, Packet Switching) switching method, system, and base station and mobile station equipment under the downlink dual-carrier or multi-carrier transmission technology. Background technique [0002] With the rapid development of the general packet radio service (GPRS, General Packet Radio Service), users have new requirements for the real-time performance of the GPRS service. For this reason, the existing standard proposes the handover processing scheme of GPRS business, and this handover processing process is as follows figure 1 As shown, corresponding to the following steps: [0003] Step 101, in the packet transfer (Packet transfer) mode, the source base station system (BSS, BaseStation System) sends a handover request message to the target BSS when determining that there is a mobile station (MS, Mobile Station) that needs to be hande...

Problems solved by technology

[0014] However, the existing packet switching (PS) domain switching method can only be applied to the switching between single carrier frequencies, and cannot meet the switching requirements of the PS domain after the introduction of downlink dual-carrier or multi-carrier transmission technology

For example, if the MS is in the downlink dual-carrier or multi-carrier transmission state and receives data on two carrier frequencies, since the existing technology only provides a switching method from one carrier frequency to another carrier frequency, it cannot realize that the MS is in Handover process under two carrier frequencies
