Problems solved by technology

These existing admission control methods are not applicable to streaming services. If admission control is to be performed on streaming services, it is necessary to conduct more adequate analysis of the usage of HSDPA channel resources and the possible impact of new streaming services. consider

Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039]The present invention provides a call admission control method, the main design idea of ​​which is: after receiving an access request for a new service, first enter the congestion state judgment process, and enter the CQI admission judgment process when it is judged that there is no congestion; then, Enter the power admission decision process when it is judged that the estimated value of the CQI report can reach the CQI threshold required by the current new service; finally, accept the current access request when the estimated value of the judged power requirement does not exceed the preset power threshold.

[0040] Wherein, the present invention is applied in access network (RAN, Radio Access Network) equipment, and is usually applied in the radio network controller (RNC) of wideband code division multiple access (WCDMA) system,...

Abstract

The present invention discloses calling admission control method. Said method includes A, judging current whether being congestion state, if then rejecting receiving current access request and ending current processing; otherwise executing step B; B, to obtain accessing new service channel quality indication CQI report estimated value, judging said CQI report estimated value whether reaching service corresponded CQI threshold, if is then executing step C; otherwise rejecting receiving current access request and ending current processing process; C, to obtain accessing new service power requirement estimated value, judging said power requirement estimated value whether exceeding predetermined power threshold, if is then rejecting receiving current access request; otherwise receiving current access request. The present invention also discloses a device. Said invented method and device can execute admission control to high real time and continuance high bit rate service.

Description

technical field [0001] The present invention relates to the technical field of call admission control, in particular to a call admission control method and device applied to High Speed ​​Downlink Packet Access (HSDPA). Background technique [0002] Currently, HSDPA is an important feature of the 3GPP R5 version. It realizes downlink high-speed data transmission through a series of key technologies such as adaptive modulation and coding (AMC), hybrid retransmission (HARQ), and fast scheduling of base stations. [0003] Since HSDPA has higher spectral efficiency than dedicated channels, the industry is considering mapping streaming services, which are expected to play an important role in the evolution of packet data services in 3G mobile networks, to HSDPA. At this time, when the HSDPA channel accepts an access request of a new streaming service, the service quality of the existing streaming service on the HSDPA channel should not be affected. Therefore, the radio network co...
