Authorization allocating method and device of HSUPA (high speed uplink packet access) network

Abstract

The invention discloses an authorization allocating method of an HSUPA (high speed uplink packet access) network. The method comprises the following steps that, Step 1, an HSUPA dispatcher allocates an authorization to a user terminal based on the service requirement of the user terminal; Step 2, the user terminal keeps the authorization until the service requirement of the user terminal changes, and the Step 1 is returned to; and the user terminal uses the authorization only when data packets need to be transmitted; and Step 3, the available load of a cell to be dispatched in a dispatching cycle is calculated based on a formula provided by the invention; and the HSUPA dispatcher can allocate the authorization to the user terminal in the cell to be dispatched more reasonably based on the calculated available load. The invention also provides a corresponding authorization allocating device of the HSUPA network. By using the method and the device, the delay of the authorization allocation existing in the HSUPA network can be avoided when a burst service occurs, thereby effectively avoiding the delay jitter of the user terminal.

Description

technical field [0001] The invention belongs to the technical field of communications, and in particular relates to a method and device for granting an HSUPA (high speed uplink packet access, high speed uplink packet access) network distribution authorization. Background technique [0002] After WCDMA network introduces the downlink HSDPA (High Speed ​​Downlink Packet Access) technology in the R5 protocol, the capacity of the WCDMA network has been greatly improved. But at the same time, another problem corresponding to HSDPA has also been put on the agenda, that is, the improvement of the service rate of uplink data. [0003] HSUPA introduces the enhanced dedicated channel (E-DCH) for high-speed uplink, and adds other related channels, puts the HSUPA functional entity MAC-e in the Node B (base station) to speed up the response speed, and adopts a variety of core key technologies, Including: hybrid automatic repeat transmission HARQ (Hybrid-ARQ, hybrid automatic repeat requ...

Problems solved by technology

[0006] (1) The impact of bit errors on delay;

[0007] (2) Impact of HSUPA scheduler on delay

[0009] In the prior art, when dealing with sudden business in the HSUPA network, for example, when clicking a web page, ping (Packet Internet Grope, Internet packet explorer) package or gaming (game), the HSUPA scheduler is based on the needs of the UE business burst The size of the sent data packet is the UE scheduling allocation authorization. Since the scheduler needs a certain amount of time from startup to allocation of the corresponding authorization, the dispatching command (Absolute grant / Relative grant) from the scheduler to the issued scheduling command takes effect It also takes a certain amount of time, so it will lead to a delay in the scheduling response, that is, the situation of delayed allocation of authorization

Therefore, according to the existing authorization allocation scheme, the system delay will suddenly increase when the user terminal processes the burst business, resulting in delay jitter when the user terminal is from no authorization to authorization.
