Problems solved by technology

Handover between base stations means that all processing entities on these protocol layers need to be re-established, and because the terminal needs an uplink synchronization process when accessing the target base station, these make the handover execution process between base stations relatively difficult. long, so the method of reserving resources in the target cell will lead to a lot of waste

Embodiment Construction

[0032] The existing long-term evolution system (LTE) has the characteristics of the mobile communication system described in the background art, and the example of the present invention refers to the implementation method in the LTE wireless communication system.

[0033] Example 1 of the preferred embodiment of the present invention is aimed at the same rapid handover method between the target base station and the source base station. The so-called fast handover method refers to that the radio resources reserved by the target base station include radio resources for transmitting uplink control signaling and A resource used to transmit user plane data blocks. In this way, when the terminal receives the first uplink resource scheduling information, it can immediately send uplink data while sending signaling, without additional uplink resource application process, so that the handover execution time is very fast. Include the following steps:

[0034] Step 101: After the source ...

Abstract

The invention discloses a switching method based on shared channels of mobile communication system, the aim of invention is used to solve the problems that the reliable coding can not be used caused by the complicated switch method and complicated switch accessing message, it includes: when base station judges that it need to be switched and happened in same station, target section distributes ID identify code and configures the wireless messages and ascending messages; target section sends the switch messages by control channels in source section; the messages include at least the wireless messages and ascending messages for ID identify codes for terminals; the terminals send switching complete commands on ascending share messages of target sections. The switching flow is terse, and reduces the switching time. The reduced switching access messages can be presented by more bytes, and the switching access messages can use the reliable coding technology, and the receiver of base station can decode easily.

Description

technical field [0001] The invention relates to a handover method based on a shared channel in a mobile communication system. Background technique [0002] The E-DCH (Extended Dedicated Channel) technology adopted in the current WCDMA system enhances the uplink data rate. In the uplink direction, the extended dedicated channel shares an uplink scrambling code with other channels (such as the dedicated channel DCH), so it can be considered that uplink channel resources are dedicated. If a hard handover occurs between base stations, the handover process is similar to the DCH handover process, that is, after receiving the physical channel reconfiguration message, the terminal changes the wireless parameter configuration at a predetermined time, and then starts communication on the uplink dedicated channel process. [0003] A mobile communication system based on shared channel switching is mainly composed of a terminal, a base station and a core network. The base stations can...
