Benefits of technology

[0011]Although the solution that uses HS-RACHs to replace RACHs for uplink transmission is proposed in the prior art, a method for releasing HS-RACH resources is not provided. As a result, the HS-RACH resources in use may be occupied all the time and cannot be released. Therefore, the procedure in the technical solution of the prior art is incomplete and may not be applied currently. In contrast, the technical solution provided in embodiments of the present invention includes: obtaining trigger information; determining to release an allocated HS-RACH resource according to the obtained trigger information; and releasing the allocated HS-RACH resource after determining to release the allocated HS-RACH resource. Therefore, the HS-RACH resources in use may be released according to actual situations. This technical solution improves the procedure for using HS-RACHs to replace RACHs for uplink transmission and is more suitable for actual applications.

Problems solved by technology

The solution that uses HS-RACHs to replace RACHs for uplink transmission is already proposed in the prior art, but a method for releasing HS-RACH resources is not provided.

first embodiment

[0038]FIG. 1 is a flowchart of a method for releasing resources in the first embodiment of the present invention. This method is applied when the UE does not change the state, and does not perform cell handover.

[0039]As shown in FIG. 1, the process includes the following steps.

[0040]Step 101: The NodeB receives the SI sent by the UE.

[0041]When using the HS-RACH to send uplink data, the UE sends the SI to the NodeB periodically or when there is new data to be sent. The SI carries the data buffer size of the UE.

[0042]The SI may be sent independently or carried in the uplink data.

[0043]Step 102: The NodeB determines to request the UE to release the resources according to the information in the received SI.

[0044]When finding that the data buffer usage indicated by the SI is lower than a certain threshold or is 0, the NodeB requests the UE to release resources and starts to release the resources related to the UE.

[0045]Step 103: The NodeB sends a release indication to the UE.

[0046]When t...

second embodiment

[0061]The following describes a method for releasing resources when the UE does not perform cell handover but changes the state according to the second embodiment of the present invention. Two scenarios are involved. FIG. 2 is a flowchart of a method for releasing resources when the RNC requests the NodeB to release resources in the second embodiment (a). FIG. 3 is a flowchart of a method for releasing resources when the UE requests the NodeB to release resources in the second embodiment (b).

[0062]As shown in FIG. 2, the process of a method for releasing resources in the second embodiment (a) of the present invention includes the following steps.

[0063]Step 201: The RNC receives measurement parameters.

[0064]The measurement parameters received by the RNC, for example, the current service data amount of the UE or QoS requirement of the UE, are sent by the UE through the NodeB. The RNC may further measure the load of the cell where the UE resides.

[0065]Step 202: The RNC determines to ch...

third embodiment

[0101]FIG. 4 is a flowchart of a method for releasing resources in the third embodiment of the present invention. This method is applied when the UE does not change the state but performs cell handover.

[0102]As shown in FIG. 4, the process of the method includes the following steps.

[0103]Step 401: The UE sends uplink data by using the HS-RACH in the current cell.

[0104]Step 402: The UE determines to reselect a cell after finding that the cell reselection conditions are met.

[0105]Here, the cell reselection condition means that a cell with good signal quality is selected when the signal quality of intra-frequency cells is poor. Assume that the UE resides in cell 1, and it determines to move to cell 2 when finding the signal quality of cell 2 is better than that of cell 1.

[0106]Step 403: The UE sends a release request to the NodeB of the original cell, that is, cell 1.

[0107]The release request sent by the UE is a special release request. For example, the ID of the logical channel with t...

Abstract

A method for releasing resources includes obtaining trigger information; determining to release an allocated high-speed random access channel (HS-RACH) resource according to the obtained trigger information; and releasing the allocated HS-RACH resource at the local end.

Description

[0001]This application is a continuation of co-pending International Application No. PCT / CN2008 / 073769, filed on Dec. 26, 2008, which designated the United States and was not published in English, and which claims priority to Chinese Application No. 200710307869.0, filed on Dec. 29, 2007, both of which applications are incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to communication technologies, and in particular, to a resource release method, communication equipment, and a network system.BACKGROUND[0003]To reduce the uplink signaling transmission delay and discontinuous packet transmission delay on a communication network, and optimize the existing random access technologies, a solution is proposed in the prior art. The solution uses the enhanced high-speed random access channels (HS-RACHs) to replace the random access channels (RACHs) to implement uplink transmission.[0004]In the technical solution of the prior art, the enhanced random access p...
