Problems solved by technology

[0004] After the IMB cell is established, a T-CPICH channel will be established. According to the existing 3GPP protocol, the NodeB (Node B) will not report the T-CPICH channel status of the IMB cell in the NodeB to the RNC (RadioNetworkController, radio network controller), and the RNC cannot Know the T-CPICH channel status of the IMB cell in the NodeB
In this way, when the T-CPICH channel in the IMB cell is abnormal, the RNC will not be able to know the abnormal situation, causing the resource status of the RNC to be inconsistent with that of the NodeB, so that the NodeB cannot handle the RNC's request to process IMB related services.

Embodiment 1

[0019] figure 1 A flow chart of a method for reporting the channel status of T-CPICH according to an embodiment of the present invention is shown, including the following steps:

[0020] Step S102, the base station NodeB checks the channel state of the T-CPICH;

[0021] The 3GPP25.433 protocol stipulates that the status of the channel is determined by two fields: Resource Operational State (ResourceOperationalState) and availability status (AvailabilityStatus). There are empty (empty), testing (intest), failed (failed), power off (poweroff), offline (offline) and other states;

[0022] After the T-CPICH channel is established, the NodeB can check the channel status of the T-CPICH. The specific checking timing and checking frequency can be set according to the needs. For example, a timer can be set to trigger the NodeB to check the T -CPICH channel status, NodeB record check result;

[0023] In step S104, the NodeB reports the channel state of the T-CPICH to the RNC.

Embodiment 2

[0029] figure 2 A flowchart of a method for reporting the channel state of T-CPICH according to an embodiment of the present invention is shown. The method is described by taking the channel state of T-CPICH reported in the audit process as an example. The method includes the following steps:

[0030] Step S202, the RNC audits the logical resources of the NodeB through an AuditRequest (audit request) message;

[0031] Step S204, NodeB obtains T-CPICH information after receiving the audit request message sent by RNC, and the T-CPICH information is the T-CPICH channel state information checked and recorded before;

[0032] Step S206, tell the logical resources of the entire NodeB to the RNC through the AuditResponse (audit response) message, and carry the cell information Time-multiplexedCPICHInformation in the cell information of the audit response (existing cells in the 3GPP25.433 protocol, indicating cell information) (T-CPICH information), the T-CPICH information indicates...

Embodiment 3

[0043] image 3 A flow chart of a method for reporting the channel state of T-CPICH according to an embodiment of the present invention is shown. The method is described by taking the resource state indication process to report the channel state of T-CPICH as an example. The method includes the following steps:

[0044] Step S302, the NodeB monitors the change of logical resources, records the T-CPICH channel state when the T-CPICH channel state changes, and immediately triggers the resource state indication process;

[0045] Step S304, the NodeB notifies the logical resources of the NodeB to the RNC through a ResourceStatusIndication (resource status indication) message, which is carried in the information element CellInformation (which is an existing information element in the 3GPP25.433 protocol, indicating cell information) of the resource status indication in this embodiment The information element Time-multiplexedCPICHInformation information (T-CPICH information), the T-...

Abstract

A method, NodeB and system for reporting channel state of Time-multiplexed Common Pilot Channel (T-CPICH) are provided in the present invention. Wherein, the above method includes the following steps: a NodeB checks the channel state of the T-CPICH; and the NodeB reports the channel state of the T-CPICH to the radio network controller. With the present invention, by employing the NodeB to check and report the channel state of the T-CPICH, the problem that the channel resource state at the radio network controller side is not consistent with the channel resource state at the NodeB side is solved, and thereby better effect of Integrated Mobile Broadcast (IMB)-related services is achieved.

Description

technical field [0001] The present invention relates to the field of WCDMA (WidebandCodeDivisionMultipleAccess, Wideband Code Division Multiple Access) mobile communication, in particular, to a method, base station and system for reporting the channel state of T-CPICH (Time-multiplexedCommonPilotChannel, time-division common pilot channel) . Background technique [0002] 3GPP (Third Generation Partnership Project, Third Generation Partnership Project) R7 protocol version defines MBSFN (MBMSsingleFrequencyNetwork, MBMS Single Frequency Network) technical specifications, as an enhanced MBMS (MultimediaBroadcastandMulticastService, multimedia broadcast / multicast service) technology, all adjacent base stations transmit synchronously For the same wireless signal, the UE can regard signals from different base stations as multipath signals, which greatly improves spectrum utilization. [0003] The 3GPPR8 protocol version introduces IMB (Integrated Mobile Broadcast) technology into...
