specific Embodiment approach

[0077] The specific implementation of the program of the present invention is as follows:

[0078] The inventive method, such as image 3 shown, including the following steps:

[0079] S301. Scan the user data queue at each sending time interval;

[0080] Each user data queue is scanned at each sending time interval TTI.

[0081] S302. Determine whether VoIP data exists?

[0082] It is judged whether there is VoIP data in each user data queue, if yes, go to step S303; otherwise, go to step S305.

[0083] S303. Determine whether there is VoIP emergency data?

[0084] In order to ensure the time delay requirement of the VoIP data packet, it is judged whether the VoIP data is urgent VoIP data, that is, whether the VoIP data needs to be sent out urgently, if yes, go to step S304; otherwise, go to step S305.

[0085] S304. Send VoIP emergency data of each user data queue according to priority;

[0086] According to formula (1):

[0087] VoIPUrgenFlag ...

Embodiment 1

[0105] There are VoIP users A and B, Streaming user C and BE user D in the network, after each user accesses the network in turn, adopts the scheme of the present invention, such as Figure 4 As shown, the specific process is as follows:

[0106] S401. Buffer user data in the MAC-hs queue;

[0107] After each user accesses the network, each user's data is sent from the RNC to the NodeB and cached in the MAC-hs queue.

[0108] S402, NodeB sets a time counter for each data packet;

[0109] The NodeB sets the time counter CurDelay to 0 for the data in each VoIP user data queue.

[0110] S403. In each TTI, the NodeB checks the data in the VoIP user data queue;

[0111] At each sending time interval TTI, NodeB checks the data of queues A and B according to the formula (1).

[0112] S404. Determine whether it is urgent VoIP data?

[0113] According to the formula (1), the data in the user A and B data queues are judged, if the VoIPUrgenFlag is TRUE, then step S405 is performed;...

Abstract

A method for dispatching access service of downlink high speed packet utilizes base station to scan user data queue at each sending-time interval then sends out IP voice emergency data precedently. The system for realizing said method comprises base station, user device and IP voice emergency data identification unit, the said system is featured as sending user data to user device by base station and utilizing said identification unit to identify out IP voice emergency data from data of media access control queue MAC-hs.

Description

technical field [0001] The method of the invention relates to the technical field of communication, in particular to a downlink high-speed packet access service scheduling method, a base station (Node B) and a system. Background technique [0002] Wideband Code Division Multiple Access (WCDMA, Wideband CDMA, Code division multiple access) realizes the sharing of data packets in terms of channel code and transmission power by introducing downlink high speed packet access (HSDPA, High speed dedicated physical control channel), and chooses to use automatic Technologies such as adaptive modulation and coding (AMC, Adaptive Modulation and Coding), hybrid automatic repeat request (HARQ, Hybrid automatic repeat request) and fast scheduling further increase the data rate. In this way, the capacity and spectrum efficiency of the system are greatly improved, and the quality of user service is also improved. [0003] On the access network side, in order to support the above-mentioned ...
