Embodiment 1

[0044] Example 1 as figure 2As shown, a kind of when the user moves from supporting F-DPCH sub-district to not supporting F-DPCH sub-district, the method that the user migrates from F-DPCH to DPCH physical channel and keeps soft handover, the steps are as follows:

[0045] Step S201: The UE reports the intra-frequency measurement report 1A event or 1C event;

[0046] Step S202: The radio network controller (Radio Network Controller, RNC) judges whether the reporting event cell supports F-DPCH, and if it supports, execute step S203, otherwise execute step S204;

[0047] Step S203: adding a wireless link;

[0048] Step S204: Waiting for the UE to report other measurement reports, when the UE reports the 1D event of the intra-frequency measurement report of the above cell, execute step S205;

[0049] Step S205: If the above-mentioned cell supports F-DPCH, the RNC decides to change the HS-DSCH serving cell, and the RNC initiates a radio link reconfiguration process to the Node ...

Embodiment 2

[0052] Example 2 as image 3 As shown, a kind of when the user moves from supporting F-DPCH sub-district to not supporting F-DPCH sub-district, the method that the user migrates from F-DPCH to DPCH physical channel and performs hard handover, the steps are as follows:

[0053] Step S301: The UE reports the intra-frequency measurement report 1A event or 1C event;

[0054] Step S302: RNC judges whether the reported event cell supports F-DPCH, if it supports, execute step S303, otherwise execute step S304;

[0055] Step S303: adding a wireless link;

[0056] Step S304: Waiting for the UE to report other measurement reports, when the UE reports the intra-frequency measurement report 1D event or the inter-frequency handover event of the above-mentioned cell, execute step 305;

[0057] Step S305: If the above-mentioned cell supports F-DPCH, the RNC decides to change the HS-DSCH serving cell, and the RNC initiates a radio link reconfiguration process to the Node B to keep the F-DPC...

Embodiment 3

[0059] Example 3 as Figure 4 As shown, there is provided a method for the user to migrate from DPCH to F-DPCH physical channel when the user moves from a cell that does not support F-DPCH to a cell that supports F-DPCH, and the steps are as follows:

[0060] Step S401: The UE is allocated a DPCH physical channel and no service is mapped to the DCH;

[0061] Step S402: The UE reports an intra-frequency measurement report 1A, 1C, 1D or 1B event;

[0062] Step S403: RNC initiates a radio link addition and deletion process to Node B and UE according to the intra-frequency measurement event;

[0063] Step S404: The RNC judges whether all cells in the current active set where the Node B and the UE have established radio links support F-DPCH, and if so, execute step S405, otherwise execute step S406;

[0064] Step S405: RNC initiates a radio link reconfiguration process to Node B and UE, and accompanied by channel migration from DPCH to F-DPCH;

[0065] Step S406: Wait for other ...

Abstract

The invention provides a method for moving between a partially special physical channel and a special physical channel, which includes the following steps, which are the channel move steps based on community move: when users move from communities supporting the partially special physical channel to the communities not supporting the partially special physical channel or from the communities not supporting the partially special physical channel to the communities supporting the partially special physical channel, the invention implements the channel move between the partially special physical channel and the special physical channel; or channel move step based on business need: when businesses required by users need to move from partially special physical channel to special physical channel, the invention implements channel move between partially special physical channel and special physical channel. The invention uses F-DPCH physical channel as much as possible to make the users only occupy a single channel code, thus saving downlink channel codes in large quantity and enhancing communities' throughput. Meanwhile, the invention can also meet requirements of user businesses and community features.

Description

technical field [0001] The present invention relates to a working method of a dedicated physical channel in a wireless communication system, in particular to a channel migration method between a fraction-dedicated physical channel (Fraction-Dedicated Physical Channel, F-DPCH) and a dedicated physical channel. Background technique [0002] The R99 standard protocol of the WCDMA mobile communication system provides users with a maximum rate of 384kbps, and hot spots can provide a rate of 2Mbps. From the perspective of the performance of the dedicated channel (Dedicated Channel, DCH) and downlink shared channel (Downlink Shared Channel, DSCH) that R99 can support for transmitting packet data, for users in general areas, the rate bandwidth provided by R99 will not be able to meet The needs of users in hotspots. Therefore, the R5 standard protocol introduces the High Speed ​​Downlink Packet Access (HSDPA) function, and at the same time introduces a High Speed ​​Downlink Shared C...
