Method for determining resource distribution priority and device thereof

Abstract

The invention discloses a method for determining a resource distribution priority and a device thereof. The method comprises the following steps: obtaining an objective transmission time-delay value of an accepted real-time service in the current resource distribution time interval; judging whether the actual transmission time-delay value of the real-time service in the current resource distribution time interval is more than the obtained objective transmission time-delay value; if yes, determining an adjustment parameter for adjusting the resource distribution priority of the real-time service based on the actual transmission time-delay value and the objective transmission time-delay value of the real-time service; and adjusting the resource distribution priority of the real-time service based on the determined adjustment parameter. By adopting the technical scheme, larger transmission opportunity can be given to the real-time service with better channel condition.

Description

[0001] This application is a divisional application of a patent application with an application date of April 18, 2008, an application number of 200810104445.9, and an application title of "Admission Control and Method for Determining Resource Allocation Priority, and Related Equipment". technical field [0002] The present invention relates to the field of communication technologies, in particular to a method and device for determining resource allocation priorities. Background technique [0003] The radio resource management (RRM, Radio Resource Management) subsystem is a very important module in the wireless network subsystem, and the call admission control (CAC, Call Admission Control) is an important part of RRM, and the call admission control module (CACM) can be based on According to the current wireless resources and load conditions of the cell and the call quality of service (QoS, Quality of Service), according to a certain algorithm, the load increase that may be ge...

Problems solved by technology

[0006] Scheme 1. The admission control scheme based on channel reservation, that is, to reserve a part of resources for handover users in advance. This scheme considers the performance of the call level, but does not consider the different QoS requirements of various services in the next generation wireless system and the QoS of the packet level. Require;

[0007] Scheme 2. The admission control scheme based on partial channel reservation, that is, according to the use of wireless resources, it is determined with a certain probability whether the call requesting user is accessed. This scheme cannot accurately judge the overload situation of the system, nor can it guarantee the QoS performance at the packet level ;

[0008] Solution 3, based on the estimated cooperative admission control scheme, that is, using information about the resource usage of adjacent cells to reserve some wireless resources for handover users, the disadvantage is the same as that of solution 1, and the system overhead is relatively large;

[0009] Solution 4. The admission control scheme based on the user's mobile information, that is, using the user's mobile information to reserve wireless resources for handover users. It is difficult to use this scheme in the system;

[0010] To sum up, the existing admission control schemes cannot meet the new requirements for admission control of the next generation wireless communication system based on OFDM technology. Users who switch over from neighboring cells) and users who initiate new access requests (that is, users who initiate new access requests in this cell); cannot support multiple service types and meet the QoS requirements of different service types; When the type brings temporary overload, continue to guarantee the service quality of the system; cannot meet the QoS requirements of the packet level and call level, etc., so that the capacity of the system cannot be guaranteed and improved under the premise of guaranteeing the quality of service
