Embodiment Construction

[0050] In order to make it easier for those skilled in the art to implement and understand the present invention, the methods and devices of the present invention are described below through embodiments with reference to the accompanying drawings.

[0051] In order to implement the device and method for realizing resource preemption according to the priority of the wireless link, three problems must be solved first: Where can this preemptive function be realized? How to determine the priority level of this user? And which user's resources can be preempted and which user's resources cannot be preempted?

[0052] First of all, the function of this preemption is realized in the base station Node B in the present invention, because:

[0053] 1. The information required to determine the priority of this wireless link is stored in Node B or can be obtained. According to this information, Node B can determine the priority level of this RL (wireless link), and Node B records this In...

Abstract

The method includes such step as mobile user through RNC sends out request for building wireless link or reconfiguration; receiving the request, base station (NODE B) determines whether there is available resources of wireless link; if yes, building or reconfiguring wireless link; if no, determining whether there is preempted wireless link used by user with low priority; if yes, deleting wireless link used by user with low priority at side of base station; then, assigning the released resources of preempted wireless link to the side wireless link; if no, not triggering preempting procedure. the invention saves time of logging on network for users with high priority, making treatment of signaling flow become simple and easy.

Description

technical field [0001] The present invention relates to mobile communication, in particular to a device and method for realizing resource preemption according to the priority of wireless links. Background technique [0002] The RL (radio link) preemption process is a strategy implemented for emergency call users or high-priority users to access the network under any circumstances. 3GPP provides a strategy that can be selected by users, so that users who make emergency calls can access the network no matter what the situation is. If the network is busy, they can access the network by preempting the resources of other low-priority users. In order to obtain the priority of the wireless link, it is necessary to obtain the priority of the wireless link according to the priority of the transmission channel. Although the current 3GPP protocol simply introduces the mapping from the priority of the transmission channel to the priority of the wireless link, there are still the followi...
