Problems solved by technology

The existing technology uses the same resource allocation method to uniformly allocate wireless resources for it. The resource allocation method can only be applied to one of the bearers, and cannot meet the speed requirements of both GBR bearers and NON-GBR bearers, that is, GBR bearers cannot be satisfied at the same time. Bearer and NON-GBR bearer resource requirements

Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] An embodiment of the present invention provides a resource allocation method, such as figure 1 As shown, the method includes:

[0027] 101. In the first stage, allocate resources for all GBR bearers and NON-GBR bearers to be allocated resources, so that the rate of each GBR bearer is equal to the corresponding GBR rate, so that each NON-GBR bearer just meets the corresponding NON-GBR bearer QCI (QoS Class Identifier, QoS Classification Identification Code) ...

Abstract

The invention discloses a resource allocation method and device and relates to the field of wireless communication techniques. The resource allocation method and device can meet the requirements of guaranteed bit rate (GBR) bearers and non guaranteed bit rate (NON-GBR) bearers for rates at the same time. The resource allocation method includes a first stage, a second stage and a third stage, wherein in the first stage, resources are allocated for bearers of all resources to be allocated, the rate of each GBR bearer is equal to a corresponding GBR rate, and each NON-GBR bearer right meets the requirements for packet delay budget (PDB) of gos class identifier (QCI) parameters of the corresponding NON-GBR bearer; in the second stage, under the circumstance that the occupation quantity of resources of all the GBR bearers does not exceed the maximum resource threshold of the GBR bearers, allocation of the resources is divided into multiple rounds, the resources continue to be allocated for each GBR bearer, and when all the GBR bearers reach the maximum bit rate (MBR), the second stage is stopped; in the third stage, allocation of remaining resources of a system is divided into multiple rounds, the resources continue to be allocated for each NON-GBR bearer, and when all the NON-GBR bearers reach the maximum limit rate, the third stage is stopped. The resource allocation method and device are mainly applied to resource allocation processes.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource allocation method and device. Background technique [0002] With the continuous breakthrough of network technology and the rapid development of application services, how to make better use of network resources to provide users with differentiated services has become a hot spot in network research. Differentiated services in an LTE (Long Term Evolution, long-term evolution) system are implemented by means of a QoS (Quality of Service, quality of service) technology. In order to implement QoS technology, the concept of EPS (Evolved Packet System, Evolved Packet System) bearer is introduced in the LTE system. EPS bearer can be regarded as UE (User Equipment, user equipment) and PDN_GW (Packet Data Network Gateway, packet data gateway ) between logic circuits. The EPS bearer is divided into GBR (Guaranteed Bit Rate, guaranteed bit rate) bearer and ...
