Embodiment Construction

[0050] At present, when channel switching is realized by establishing a new wireless link, a different CRNC and NB communication context must be used to identify a user in the network, which will increase the processing complexity of the system and may cause The user's business is temporarily interrupted.

[0051] When channel switching is performed, if only one NB communication context is still used to identify a user, the above problem can be solved.

[0052] When performing channel switching, there are many ways to use a NB communication context to identify a user, and the present invention adopts a simple and easy method.

[0053] When performing cell handover in NB, the method adopted by the present invention is to first add a wireless link for the user, notify the user to transfer to the newly added wireless link and continue to communicate with the network side, and then delete the user's original wireless link.

[0054] When adding a wireless link for a user, the RNC...

Abstract

The invention discloses a channel switch method in base station, including: adding new wireless link for UE which needs to carry out a channel switch in the base station, informing the relative message of the newly added wireless link to the UE; after the UE is configured according to the relative message of the added wireless link, deleting the original wireless link of UE. It can be seen that, during the channel switch in NB, by adding wireless links for users, not adding new wireless link for users, RNC does not need to distribute a new CRNC communication context for the belonged user, and NB can also use the original communication context of user to label the user. Thereby, the problem brought by newly established wireless link is solved, the complexity for treating the system is reduced, and the possibility of service interruption is eliminated. The invention also discloses a channel switch device in base station, and a signaling path switch method in channel and a device.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a cell switching method and device in a base station for High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access), and a channel switching method and device in a cell. Background technique [0002] After the user establishes the HSDPA service in a cell, when the user moves between different cells in the same NB, handover is required to maintain the continuity of the user service. According to the characteristics of the cells in the NB, it can be divided into switching from cells supporting HSDPA services to cells not supporting HSDPA services, switching from cells supporting HSDPA services to cells supporting HSDPA services, and switching from cells not supporting HSDPA services to cells supporting HSDPA services. There are three cases of handover of cells supporting HSDPA services. In addition, when the user's service attributes and ...
