Problems solved by technology

Because the network side cannot successfully match the global cell ID in its own stored cell list according to the cell local ID reported by the mobile station, the network side cannot establish a communication link of the cell for the mobile station, thus resulting in handover failure and eventually triggering Call drop seriously affects the service quality of the user and degrades the communication quality of the mobile station

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0037] The flow chart of this embodiment is as follows figure 1 shown, including the following steps:

[0038] Step 101: Under the control of the network side, the mobile station periodically measures the serving cell where it is located and the neighboring cells adjacent to the serving cell, and reports the measurement results to the network side. Wherein, the measurement result carries the local identification of each cell measured by the mobile station.

[0039] Step 102: The network side searches the current cell list of the mobile station according to the local identities of the cells carried in the measurement results, and identifies the global identities of the cells according to the local identities. After the cell identification is completed, i...

Abstract

The method comprises: a) according to local ID of each cell carried in the measurement report reported from mobile station, the network side identifies the global ID of each cell, and according to the identified global ID, decides if there is a neighboring cell missing the match; if yes, then entering step b; otherwise, entering step c; b) according to local ID of each neighboring cell missing the match and the cell parameter database, identifies the global ID of each neighboring cell missing the match; for the neighboring cell missing the match, which is identified out its global ID, and the cell in step a, executes the next switch process; c) for the cell which is identified its global ID, executes the next switch process.

Description

technical field [0001] The invention relates to handover technology, in particular to a handover method for identifying missing adjacent cells. Background technique [0002] In the existing Code Division Multiple Access (CDMA) cellular mobile communication system, since the base station’s transmission power is limited within a certain range, when the mobile station leaves one cell and enters another cell, the original signal received by the mobile station The cell signal is bound to become weaker and weaker, while the received signal entering the cell will become stronger and stronger. In order to maintain the communication quality of the mobile station, the connection of the mobile station must be switched from the original base station to the newly entered base station with stronger signal. This is the concept of handover in the cellular mobile communication system. [0003] In the mobile station-assisted handover strategy of the CDMA cellular mobile communication system,...
