Problems solved by technology

Since the MS has just moved to the second cell, its normal communication in the second cell may take a certain amount of time. When the BSC receives the FLUSH-LL message, the TBF between the MS and the first cell will be released in most cases , which will cause the loss of packet data and seriously affect the data communication related to MS

Embodiment Construction

[0040] It should be clear that the embodiments described below are only a part of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] Such as figure 1 and figure 2 as shown, figure 1 It is a schematic diagram of an application scenario of an embodiment of the present invention, figure 2 It is a schematic diagram of a method for transferring packet data in a wireless network according to Embodiment 1 of the present invention. combine figure 1 and figure 2, the BSC in the figure controls BTS1 of the first cell and BTS2 of the second cell, BTS1 and BTS2 are responsible for signal reception and transmission processing when the network side performs mobile communication with MS, and the BSC communicates with the SGSN. The BSC pre-establishes the BSSGPRS...

Abstract

A method for transferring packet data in a wireless network and a base station controller (BSC) thereof are provided in the present invention. The technical key points of the present invention are as follows: before the BSC receives the message sent by the Serving GPRS Support Node (SGSN) for requesting the acknowledgement of a cell update in the mobile station (MS), the packet data of a first cell to be originally sent to the MS is transferred to the temporary block flow (TBF) of the MS and a second cell, and is sent to the BTS of the second cell by the TBF of the MS and a second cell, as last, is sent to the MS by the BTS of the second cell. The packet data loss resulting from the MS moving from the first cell to the second cell can be effectively decreased, the normal data communication related to the MS can be ensured, and the retransmission rate of the packet data after the cell update can be reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, more specifically, the present invention relates to a method for transferring packet data in a wireless network and a base station controller. Background technique [0002] The General Packet Radio Service (GPRS) is a bearer service in the Global System for Mobile Communications (GSM). Generally, one or more subnets are included in the packet radio network, and each subnet includes some packet data service nodes (Service Node, SN). In this application, these SNs are called Serving GPRS Support Nodes (Serving GPRS Support Node, SGSN) ). In such a manner, the SGSN can provide a packet service for a mobile station (Mobile Station, MS) through a base station controller (Base Station Controller, BSC). The main functions of SGSN include routing and forwarding of packet data packets, authentication and encryption, session management, mobility management, logical link management, bill gen...
