Problems solved by technology

However, if the RNC reduces the number of HS-PDSCH channels before the new HSDPA service is accessed based on a certain mechanism, the new HSDPA service will not be able to be accessed, and the HS-PDSCH triggered by the rejection of the HSDPA service The channel increase operation has no effect. If this situation occurs repeatedly, it may lead to frequent increase or decrease in the number of HS-PDSCH channels, resulting in system instability.

Embodiment Construction

[0017] Below in conjunction with specific embodiment, the technical problem to be solved by the present invention is further described:

[0018] Such as figure 1 As shown, the present invention provides a method for dynamically adjusting high-speed physical downlink shared channel code resources, which mainly includes the following steps:

[0019] When the radio network controller receives an HSDPA service call, if the Iub port traffic is sufficient, the HSDPA call will be rejected due to insufficient downlink data throughput in the current cell and the HS-PDSCH channel code resources planned by the cell. , now the radio network controller will trigger the code resources of the HS-PDSCH channel, increase the number of HS-PDSCH channels, and start the resource recovery timer, and set the timeout time of the timer, the timeout time set by the timer should be greater than The time interval for the user to initiate a high-speed downlink packet access service call again;

Abstract

The invention discloses a dynamic adjustment method of code resources in a high speed physical downlink shared channel. The method mainly comprises the following steps: after the number of the high speed physical downlink shared channel configured by a radio network controller is increased on the basis of initial configuration, a code resource recovery timer is opened, and the expiration time of the timer is set; the radio network controller can only keep or increase the number of the prior high speed physical downlink shared channel before the resource recovery timer expires; when the resource recovery timer expires, if the high speed downlink grouping access service does not exist in a prior cell, the number of the prior high speed physical downlink shared channel is recovered into the number of the initial configuration. By adopting the technical proposal provided by the invention, the code resource of the channel can be utilized fully, so that the system has stable performance, and the transmission of downlink high speed data is realized.

Description

technical field [0001] The present invention relates to wideband code division multiple access (WCDMA, Wideband Code-Division Multiple Access) mobile communication technology, specifically, relate to the channel of downlink physical channel in the cell that supports high-speed downlink packet access (HSDPA, High Speed ​​Downlink Packet Access) The code distribution method. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA) is the key technology of Wideband CDMA (WCDMA, Wideband Code-Division Multiple Access) system, through adaptive modulation and coding (AMC), hybrid retransmission (HARQ) and fast scheduling of base stations (NodeB), etc. Measures to achieve downlink high-speed data transmission. [0003] In the WCDMA system supporting the HSDPA service, data is transmitted in the downlink direction through a High Speed ​​Physical Downlink Shared Channel (HS-PDSCH, High Speed ​​Physical Downlink Shared Channel). According to the agreement, the prima...
