Embodiment approach

[0086] 1. Keep the data structure of the variable TRIGGERED_1G_EVENT defined in the existing 3GPP TS25.331 (V4e0) protocol, as shown in Table 1 below:

[0087] Information

Embodiment 1

[0088] Embodiment 1 realizes the TDD CDMA system co-frequency measurement report according to the following process:

[0089] 1) After the UE establishes the RRC connection, the RNC sends a measurement control message (1G event).

[0090] 2) After receiving the 1G event measurement control message, the UE initializes the relevant variables, sets the variable TRIGGERED_1G_EVENT to null, and records the current best cell information BEST_CELL as the current serving cell.

[0091] 3) The UE monitors a group of same-frequency measurement cells according to the configuration of the network, and periodically measures the pilot strength of these cells.

[0092] 4) The UE compares the pilot measurement result of the same-frequency neighboring cell with the pilot measurement value of the serving cell.

[0093] If a cell meets the following conditions, the UE will add the cell information to the variable TRIGGERED_1G_EVENT:

[0094] ①The pilot frequency of this cell is better than the...

Embodiment 2

[0130] Embodiment 2 realizes the TDD CDMA system co-frequency measurement report according to the following process:

[0131] 1) After the UE establishes the RRC connection, the RNC sends a measurement control message.

[0132] 2) After receiving the 1G event measurement control message, the UE initializes the relevant variables and sets the variable TRIGGERED_1G_EVENT as the serving cell.

[0133] 3) The UE monitors a group of same-frequency measurement cells according to the configuration of the network, and periodically measures the pilot strength of these cells.

[0134] 4) The UE compares the pilot measurement result of the same-frequency adjacent cell with the pilot measurement value of the cell given by TRIGGERED_1G_EVENT.

[0135] If a cell meets the following two conditions, the UE replaces the original cell in the variable TRIGGERED_1G_EVENT with the information of the cell:

[0136] ①The pilot frequency of this cell is better than the pilot frequency of the cell g...

Abstract

The invention relates to a common-frequency measure report method of time-division duplex code division multiple access system, used to send IG measure report to the wireless network controller, wherein said method comprises: the user device receives the IG event report parameter information sent from the controller, to initialize the IG event; based on the network setting, detecting one group of common-frequency measure region, and periodically measuring the pilot strength of these regions; based on the measured result, processing IG event judgment; if the result is the best, the region changes and lasts preset time, to send the common-frequency measure report to the controller. With said invention, the best region detected by UE can be informed to the network to confirm the right switch of region.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for co-frequency measurement report of a time division duplex code division multiple access system. Background technique [0002] In the TDD CDMA (Time Division Duplex Code Division Multiple Access) system, the existing 3GPP (Third Generation Partnership Project) specification provides an event-triggered co-frequency measurement reporting method (1G event, that is, the UE monitors the co-frequency It is preferable to trigger a measurement report when the cell changes). The network side specifies the relevant parameters required by the 1G event. When the UE (User Equipment) is in the CELL_DCH (Cell Dedicated Channel) state and monitors the change of the best cell with the same frequency according to the measurement control parameters, the 1G event can be triggered. When the network side receives the 1G event report, it can initiate a handover process. [00...
