Embodiment Construction

[0027] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that components, procedures, processes, and representations that are not relevant to the present invention and known to those of ordinary skill in the art are omitted from the drawings and descriptions for the purpose of clarity.

[0028] The SPS is a concept defined for resource scheduling for periodic services, such as VOIP (Voice Over Internet Protocol, VoIP) services.

[0029] Correspondingly, compared with the dynamic scheduling service, the SPS service is a semi-static periodic transmission service, that is, the size of the service packet and the arrival time interval remain unchanged for a period of time, and it needs to be pre-allocated at one time A resource with a certain repetition period and repetition length, and once allocated, its exclusiveness to the resource must be guaranteed.

[0030] Wherein, the repetition period in...

Abstract

The invention relates to a resource allocation method and device. The method comprises the following steps of: acquiring a semi-persistent scheduling (SPS) service to be accessed into a system and a lowest common multiple of the service periods of all SPS services accessed into the system; checking a resource at corresponding time points of the system within the time range of the lowest common multiple by using the service period of the SPS service to be accessed into the system as a time interval so as to judge whether the resource of the system at the corresponding time points meet the resource allocation requirement of the SPS service to be accessed into the system or not; and allocating the resource to the SPS service to be accessed into the system under the condition that the resource is determined to meet the resource allocation requirement of the SPS service to be accessed into the system at all corresponding time points within the time range in the resource judging step. The resource allocation method and device provided by the invention can be used for resource allocation and reservation for the SPS service newly appearing in HSPA+ (High Speed Packet Access Evolution).

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a resource allocation method and device. Background technique [0002] Resource allocation in existing HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) and HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) usually adopts the resource pool method, if the remaining If the available resources, including time slots, code channels or power, are sufficient for the resources required by the user for this scheduling, resource allocation can be performed for the user, and the resources allocated to the user this time are deducted from the remaining system resources. Since HSUPA and HSDPA use dynamic scheduling and allocation, and only allocate resources within the length of one subframe (time point) at a time, it is only necessary to judge the remaining system resources in one subframe to determine whether ...
