A multi-service resource allocation method and device

Abstract

Embodiments of the present invention provide a multi-service resource allocation method and device. The method includes: obtaining the number of uplink subframes NUL in the uplink and downlink subframe ratio of the cell and the PBR and uplink minimum guaranteed bit rate ULMinBR corresponding to the QCI level service; using NU , PBR and ULMinBR calculate the initial BSD value N; find the preset BSD interval that matches the initial BSD value N, and determine the upper limit value M of the BSD interval as the current BSD value, M is not less than N; combine PBR and the current BSD value M , and the obtained priority of the logical channel corresponding to the QCI level service is sent to the user terminal, so that the user terminal can calculate the bucket? size value, and allocate resources for multiple services based on the uplink resource authorization sent by the base station. By comprehensively considering the QCI level and the minimum guaranteed bit rate of the service, BSD is configured to achieve the purpose of rationally allocating uplink resource authorization.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-service resource allocation method and device. Background technique [0002] When a UE (User Equipment, user equipment) needs to transmit uplink data, it first needs to send a scheduling request to the base station, and the base station performs resource allocation, and then performs uplink resource authorization to the UE. Because the base station sends an uplink resource grant is a user-specific behavior, it cannot be finely differentiated into logical channels. Therefore, after the UE receives the uplink resource grant from the base station, it needs to provide users with different priorities according to the logical channels used by the UE. Resource allocation for multiple businesses. [0003] When the UE allocates resources for multiple services, on the one hand, it must consider the priority of the logical channel (in order to ensure that the service...

Problems solved by technology

This method of statically configuring services based solely on QCI levels cannot meet the satisfaction requirements of services with the same QCI level but different minimum guaranteed bit rates

Because after RRC configures PBR, if the smaller the BSD is configured, the smaller the bucketsize value will be, the smaller the amount of data that can be transmitted by a service on this logical channel at a time, which may result in a higher minimum guaranteed bit rate The business will never be satisfied, resulting in a decline in the satisfaction of the business; and if the BSD configuration is too large, the bucketsize value will be larger, and the amount of data that the business can transmit on the logical channel at a time will be greater than the minimum Guaranteed bit rate requirements, but under the premise that the uplink resource authorization sent by the base station is certain, this will cause low-priority services to not be scheduled, and the uplink "starvation" phenomenon of low-priority services will occur
