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...
