An apparatus and method are provided for performing scheduling in a Node B for data transmission of a user equipment (UE) in a mobile communication system supporting an enhanced uplink dedicated channel (E-DCH). The Node B receives, from a radio network controller (RNC), scheduling assistance information for an uplink service to be provided from the UE. The Node B estimates a data amount for the uplink service on the basis of the scheduling assistance information in each scheduling period. The Node B schedules data transmission for the uplink service according to the estimated data amount.

A mobile communication system includes a first base station configured to be controlled by a first radio network controller, and provide an address of an extension transmission/reception device to user data received from a first mobile station, and the extension transmission/reception device configured to be controlled by the first radio network controller or a different second radio network controller, and provide an address of a second base station, which is controlled by the second radio network controller, to user data received from the first base station.

The invention discloses a method for reallocating resources. The method comprises the following steps that: a node base (NodeB) performs strong channel detection on user equipment (UE) and reports the obtained strong channel information of the UE to a radio network controller (RNC); and the RNC reallocates the resources for the UE according to the strong channel information of the UE reported by the NodeB. By the method, dedicated physical channel (DPCH) space division can be realized so as to improve carrier capacity and service quality; and a cell can be formed by performing path combination on a radio remote unit (RRU) with capacity of supporting different frequency bands.

The invention discloses a repositioning processing method which comprises the following steps: the type of repositioning is as follows: when the repositioning does not involve a service radio network subsystem of user equipment, a target radio network controller (RNC) checks out that an encryption algorithm currently used by a source RNC in a repositioning request message is not matched with the encryption algorithm selected by a target RNC; and the target RNC returns a repositioning failure message to the source RNC. The invention also discloses a repositioning processing system. In the system, when the encryption algorithm currently used by the source RNC is not matched with the encryption algorithm selected by the target RNC, the target RNC returns the repositioning failure message to the source RNC through a repositioning failure message feedback unit. By adopting the method and the system, the problem of repositioning process failure caused as the encryption algorithm selected by the target RNC is different from the encryption algorithm currently used by the source RNC in the scene of SRNS repositioning not involving the UE can be solved.

The invention discloses an interference optimization method when in cell switching, comprising the following steps: after initiating a cell switching process, a radio network controller (RNC) sends areconfiguration message to UE and sends a special burst control frame to a base station where a source cell is located; the special burst control frame carries indicating information for stopping sending descending special burst actively, and the base station stops sending the downstream special burst actively when the indicating information does not have downstream data; after the switching is infailure, the RNC sends the special burst control frame to the base station, the special burst control frame carries indicating information for restoring to send the downstream special burst actively,and the base station sends the downstream special burst actively when the indicating information does not have the downstream data. The interference optimization method can improve switching successrate.

The invention relates to CRC methods based on an Iub FP frame extension field in a TD-SCDMA system and belongs to the technical field of wireless communication. A method is applied to an RNC (Radio Network Controller). The method comprises the following steps that S1, the RNC detects a block error rate of downlink data at an Iub interface; S2, the RNC judges whether to start or close CRC of an Iubinterface downlink FP frame according to the block error rate; and S3, the RNC establishes the downlink FP frame according to a judgment result of the S2 and sends the downlink FP frame to a Node B,and the Node B judges whether to carry out CRC analysis or not according to an extension field of the received downlink FP frame. The method applied to the Node B comprises the following steps that S1, the Node B receives the Iub interface downlink FP frame sent by the RNC; and S2, the Node B judges whether to carry out the CRC analysis or not according to the extension field of the Iub interfacedownlink FP frame. According to the methods, the problem that Iub interface transmission bandwidth and processing capacity for CRC16 computing are wasted due to the fact that payload CRC16 must be carried in the Iub interface downlink FP frame and dynamic configuration cannot be carried out is solved.
