Parameter acquisition method as well as rate control method and control device

Abstract

The embodiment of the invention relates to a parameter acquisition method, which comprises the steps of acquiring an aggregate maximum bit rate (AMBR) parameter of user equipment (UE) and acquiring the information of a service controlled by the AMBR. The embodiment of the invention also relates to a rate control method, which comprises the steps of: acquiring the AMBR parameter of the UE and controlling non-GRB service data rate on the basis of the acquired AMBR parameter. The parameter acquisition method and relevant equipment in the embodiment ensure that the authorized AMBR parameter is sent through an IU (International Unit) interface in a UMTS (Universal Mobile Telecommunications System) or a TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) system, thereby being convenient for acquiring the AMBR parameter. Moreover, the rate control method and the relevant equipment of the embodiment realize the sharing of rate authorization by utilizing the AMBR parameter to control a non-GRB service data rate.

Description

Technical field [0001] The embodiment of the present invention relates to the field of mobile communication, in particular to a parameter acquisition method, rate control method and control device. Background technique [0002] In order to maintain the competitiveness of the wireless access technology Universal Mobile Telecommunications System (UMTS) technology of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP), and to evolve for a longer time, 3GPP has launched a wireless The Long Term Evaluation (LTE) project of access technology aims to develop a wireless access technology framework with high data rate, low response time and optimal packet access. [0003] Therefore, when the UMTS system and the LTE system coexist, the two must maintain mobile compatibility. A very important compatibility is the quality of service (Quality of service, QOS) compatibility. [0004] For UMTS QOS, the maximum bit rate (Maximum Bit Rate, MBR) and the guaranteed bit ra...

Problems solved by technology

However, the LTE QOS parameter user equipment UE-total maximum bit rate (Aggregate Maximum Bit Rate, AMBR) controls the sum of the rates of all non-GBR services. Non-GBR services do not have a separate maximum bit rate requirement, but the sum of rates is limited by the UE -AMBR

[0005]Because of the independent control of the rate between the services of the UE in the UMTS system, when the rate of a service becomes very low, other services cannot use the remaining subscription authorization of the service , unable to share rate authorization

For example, the maximum rate of two services signed by a UE is 2M and 1M respectively. When the actual rate of the previous service is only 1M, the rate of the latter service cannot exceed 1M, and the remaining 1M authorization of the previous service cannot be used.

Moreover, when a UE is moving from LTE to UMTS, due to different control methods, the rate control result may differ greatly from the original rate, and may suddenly become smaller, affecting service usage, or even failing to use the service.
