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 (Radio Network Controller, Radio Network Controller). 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 3GPP 25.433 protocol stipulates that the state of the channel is determined by two fields: Resource Operational State and Availability Status. The resource operation state has two states: Enabled and Disabled. Statuses include empty, in test, failed, power off, off line, etc.;

[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.

[0024] The NodeB carries the T-CPIC...

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 Audit Request (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 by an Audit Response (audit response) message, and carry the cell Time in the cell information of the audit response (for existing cells in the 3GPP25.433 protocol, indicating cell information) - multiplexed CPICH Information (T-CPICH information), the T-CPICH information indicates the T-C...

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 Resource Status Indication (resource status indication) message, and in this embodiment, the cell information indicated by the resource status (being an existing cell in the 3GPP 25.433 protocol, indicating cell information) Carry information element Time-multiplexed CPICH Information (T-CPICH information), and the T-CPICH information indicates the T-CPICH channel status...

Abstract

The invention discloses a method and a system for reporting the channel state of a time-multiplexed common pilot channel (T-CPICH), and a base station. The method comprises the following steps of: checking the channel state of the T-CPICH by using the base station; and reporting the channel state of the T-CPICH to a radio network controller. In the invention, the base station checks and reports the channel state of the T-CPICH to solve the problem of channel resource state inconsistency between a radio network controller side and a base station side and further achieve the effect of better realizing an integrated mobile broadcast (IMB) service.

Description

technical field [0001] The present invention relates to the field of WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) mobile communication, in particular, relates to a channel state of reporting T-CPICH (Time-multiplexed Common Pilot Channel, time-division common pilot channel) Method, base station and system. Background technique [0002] 3GPP (Third Generation Partnership Project, Third Generation Partnership Project) R7 protocol version defines MB SFN (MBMS single Frequency Network, MBMS single frequency network) technical specifications, as an enhanced MBMS (Multimedia Broadcast and Multicast Service, multimedia broadcast / multicast Business) technology, all adjacent base stations transmit the same wireless signal synchronously, and the UE can regard the signals from different base stations as multipath signals, which greatly improves the spectrum utilization. [0003] The 3GPP R8 protocol version introduces IMB (Integrated MobileBro...
