Problems solved by technology

However, this solution does not solve the problem of long switching time, and will still cause the loss of delivered HSDPA service data to a certain extent, and cannot truly realize the lossless switching of HSDPA services in the base station

Embodiment 1

[0035] figure 1 It is a flow chart of Embodiment 1 of the present invention. Such as figure 1 As shown, Embodiment 1 of the present invention mainly includes:

[0036] Step 101, when the RNC determines that it is necessary to perform handover in the base station for the UE, it notifies the base station to which the UE belongs to the instruction information indicating that the source cell and the target cell share the Iub port transmission path.

[0037] In this step, when the RNC determines that the handover in the base station needs to be performed for the UE according to the measurement report reported by the UE, the base station is notified through the indication information that the source cell shares the Iub port transmission path with the target cell that the base station does not need to establish an Iub port for the target cell. Iub mouth transmission path, but use the Iub mouth transmission path that has been set up for the source cell, like this, just save the time...

Abstract

The invention discloses a handover method in a base station, comprising: when RNC determines that the handover in the base station needs to be performed for the UE, the base station is notified of the indication information that the source cell and the target cell share an Iub port transmission path; the base station establishes a target for the UE. The internal data flow path of the cell, according to the indication information, the Iub port transmission path of the source cell that has been established for the UE is used as the Iub port transmission path of the target cell, and it is mapped with the internal data flow path of the target cell, triggering RNC sets the Iub port transmission path of the target cell to a synchronous state; RNC triggers to set up the air interface wireless link of the target cell for the UE; UE triggers the air interface wireless link of the target cell to synchronize; if the synchronization is successful, the RNC triggers Delete the resources configured for the UE in the source cell; otherwise, the RNC triggers deletion of the resources configured for the UE in the target cell. The invention can effectively shorten the switching time.

Description

technical field [0001] The invention relates to a handover technology in a mobile communication system, in particular to a lossless handover method in a base station of a high-speed downlink packet access (HSDPA) network. Background technique [0002] At present, the TD-SCDMA system has established test networks and pre-commercial networks in many cities, and will establish wireless networks in other cities. The optimization of network switching performance, especially the performance optimization of HSDPA network, is a very important process. [0003] In the existing cell handover method in the base station, the radio network controller (RNC) determines whether cell handover is required according to the measurement report reported by the user equipment (UE), and if necessary, sends a radio link establishment / Add a request to trigger the base station to establish the transmission path of the Iub port (the interface between the base station and the RNC) for the target cell,...
