Embodiment 1

[0044] Referring to Figure 1, using the method of measurement control signaling, taking LTE neighboring cells as an example, the implementation steps include:

[0045] Step 101: After the terminal establishes an RRC (Radio Resource Control Protocol) connection, the serving cell A sends measurement control signaling to the terminal. In addition to the measurement type, event trigger conditions, and reporting rules, the measurement control signaling also includes measurement control signaling. The measurement object part of the order indicates whether the GCI corresponding to the underlying protocol cell ID of the adjacent cell is locally unique. In this embodiment, it is necessary to indicate that the GCI corresponding to the adjacent cell whose physical cell ID is "PCI" is not locally unique. For example, A flag bit to indicate;

[0046] The GCI corresponding to the underlying protocol cell ID of an adjacent cell is locally unique, which means that in a certain cell, the globa...

Embodiment 2

[0054] Referring to Figure 2, using the method of measurement control signaling, taking UTRAN neighboring cells as an example, the implementation steps include:

[0055] Step 201: After the terminal establishes an RRC connection, the serving cell A sends measurement control signaling to the terminal. The measurement control signaling not only includes the measurement type, event trigger conditions, reporting rules, etc., but also indicates the absolute frequency point in the measurement object as " F", the GCI corresponding to the neighboring cell whose scrambling code is "PSC" is not locally unique;

[0056] Step 202: After receiving the above measurement control signaling, the terminal starts the measurement process according to the instruction of the measurement control signaling;

[0057] Step 203: When a measurement event is triggered, or the terminal needs to periodically report a measurement report, the terminal finds that the measurement report includes the measurement...

Embodiment 3

[0064] Referring to Figure 3, using the method of re-reporting, taking GERAN neighboring cells as an example, the implementation steps include:

[0065] Step 301: After the terminal establishes an RRC connection, the serving cell A sends measurement control signaling to the terminal, and the measurement control signaling includes measurement type, measurement target, event trigger conditions, and reporting rules, etc.;

[0066] Step 302: After receiving the above-mentioned measurement control signaling, the terminal starts the measurement process according to the instruction of the measurement control signaling;

[0067] Step 303: When a measurement event is triggered or the terminal needs to periodically report a measurement report, the terminal reports the measurement report to the serving cell, and the terminal finds that the measurement report includes the measurement result of the neighboring cell B; the measurement report uses the absolute value of the neighboring cell B ...

Abstract

The invention relates to a method of measurement and control in a wireless cellular communication system. In the process of measurement control and measurement report of adjacent cell which is initiated in a service cell, the service cell indicates whether a global cell ID corresponding to a bottom layer protocol ID used for identifying adjacent cell is a local uniqueness; after a terminal achieves the measurement of the adjacent cell, if the global cell ID corresponding to the bottom layer protocol ID of adjacent cells which are required to be reported is not the local uniqueness, and the adjacent cells are identified by the global cell ID in the measurement report. When a bottom layer protocol cell ID is corresponding to a plurality of global cell IDs, the invention ensures that the service cell can exactly identify corresponding adjacent cells in the measurement result of the terminal and ensures normal wireless resource management and operation.

Description

technical field [0001] The present invention relates to the technical field of wireless cellular communication, in particular to a measurement control method in a wireless cellular communication system, which can resolve possible ambiguity of neighboring cells. Background technique [0002] In a wireless cellular communication system, each cell has a unique global cell ID, and a terminal can obtain the global cell ID by reading system messages. In addition, in the measurement control message and measurement report, the cell ID of the underlying protocol of the adjacent cell is often used to represent it. For example, in the WCDMA (Wideband Code Division Multiple Access) system, it is represented by the primary scrambling code plus frequency of the cell; LTE ( In the long-term technology evolution) system, it is distinguished by the physical cell ID on the cell synchronization channel; in the GERAN (GSM-EGPRS radio access network?) system, it is represented by frequency plus ...
