[0047] The above messages for SPS service authorization can only indicate the authorized user. According to the existing SPS service authorization method, after the system authorizes the user for the first time, and then sends an authorization message to the UE, the UE will consider the authorization message as It is used to re-authorize all current SPS services of the UE. Specifically, when the authorization is for the configuration of physical resources for SPS services, the UE will use the physical resources specified in the latest received authorization message to perform SPS services. transmission, and the previously authorized physical resources will be invalid. When the authorization is for the release of SPS service

Example Embodiment

[0055] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] The core idea of ​​the present invention is: the base station first classifies the SPS services that need to be authorized according to the SPS service cycle and QoS requirements, and authorizes different types of SPS services on different subframes, when the authorization is for the authorized When physical resources are reconfigured or released, the authorization effective time is mapped to the corresponding authorized physical resource time point, so that the UE can determine which authorized physical resources this authorization is for according to the authorized effective time. In this way, the UE can add or delete the physical resources of the currently authorized SPS service according to the authorization, so as to realize i...

Abstract

The invention discloses a method for authorizing semi-persistent scheduling (SPS) services. The method comprises the following steps of: classifying the SPS services required to be authorized at a base station according to the periods of the SPS services and quality of service (QoS) requirements; authorizing different SPS services on different subframes; and when authorization is reconfigured or released for authorized physical resources, corresponding authorization effective time to time points at which the corresponding authorized physical resources are positioned, so that the resources corresponding to the authorization can be determined by user equipment (UE), and the independent authorization for the SPS services with different SPS service periods and different QoS requirements can be realized. Therefore, the requirements of different SPS services can be met and the effectiveness of resource allocation at the network side can be improved.

Description

technical field [0001] The invention relates to the semi-persistent scheduling (SPS) technology in the mobile communication system, in particular to the authorization method of the SPS service in the evolved high-speed data packet access (HSPA+) system. Background technique [0002] At present, in the HSPA+ system, the physical resources (ie, slot and code channel resources) of the downlink semi-persistent scheduling (SPS) service of the user equipment (UE) are released by using the high-speed shared control channel order 1 (HS-SCCH orderTypeA) message, Use the High Speed ​​Shared Control Channel Grant Type 2 (HS-SCCH type2) message to configure or reconfigure the physical resources of the UE's downlink SPS service, and use the Enhanced Dedicated Channel's Absolute Grant Channel Order (E-AGCH order) message to configure the UE's uplink The physical resources of the SPS service are released, and the physical resources of the uplink SPS service of the UE are configured or reco...
