Embodiment Construction

[0015] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] First of all, for the convenience of explanation, explain the professional terms used in this article:

[0017] Actual rate to guaranteed rate ratio (PBR / GBR): The ratio of the actual air interface rate (HS-DSCH Provide Bit Rate) of a certain scheduling priority service set on the HSDPA channel to the sum of the guaranteed rates of the service set.

[0018] Streaming service rate ratio (GBR Ratio): the ratio of the guaranteed rate of a stream service in a service set with a certain priority to the sum of the guaranteed rates of all services in the set.

[0019] Weight: The abbreviation of HS-DSCH Required Power Per UE Weight, which means that the power required by a certain S-type service in a certain priority service set to reach its guaranteed rate accounts for all the S-type services in the set that require to reach the ...

Abstract

The invention discloses a service congregation selection method and a method for reducing a load of a high-speed downlink grouping access channel. The method used for reducing the burden of the high-speed downlink grouping access channel includes the following steps: step 102, when the high-speed downlink grouping access channel is overloaded, the service congregation assembled by at least one service is selected from a load of the high-speed downlink grouping access channel; step 104, the service of the adjustable service congregation is moved to a special transmission channel, and the service of the adjustable service congregation is switched compulsively to other cells or is off-line compulsively to lighten the load of the high-speed downlink grouping access channel. By adopting the invention, the load of the high-speed downlink grouping access channel can be lightened timely, thereby, an utilization ratio of the resource is improved.

Description

technical field [0001] The invention relates to the communication field, and more specifically relates to a method for selecting a service set and a method for reducing the load of a high-speed downlink packet access channel. Background technique [0002] In the 3GPP standard, in order to meet the rapidly growing demand for high-speed mobile data services, especially mobile Internet services, researchers proposed an enhanced technology based on the UMTS standard, which is High Speed ​​Downlink Packet Access (High Speed ​​Downlink Packet Access). Access, referred to as HSDPA) technology. [0003] HSDPA is an enhanced scheme proposed by 3GPP Release 5, which is applicable to both WCDMA and TD-SCDMA systems. The main goal of HSDPA is to provide high-speed support for "best effort" packet data packets. [0004] HSDPA mainly adopts High Speed ​​Downlink Shared Channel (HS-DSCH for short) technology to enhance the data throughput of the air interface. In Release 4, a Dedicated ...
