Problems solved by technology

However, there are many reasons why the RRC connection fails, not only because of poor signal quality, so according to the Chinese patent application, cell reselection is often initiated when the signal quality is not bad, resulting in frequent cell reselection processes

Embodiment Construction

[0022] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0023] For the convenience of description, the embodiments of the present invention are described by taking its application in Global System For Mobile Communication (GSM) as an example. However, other communication systems in wireless communication, such as Wide Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (Code Division Multiple Access, CDMA2000), Time Division Synchronous Code Division Multiple Access (Time Division Multiple Access) Division-Synchronous Code Division Multiple Access, TD-SCDMA) can support the method of the present invention.

[0024] In a GSM cellular network, cell reselection usually occurs in the following situations:

[0025] 1) The C1 value of the serving cell is less than 0 for more than 5 seconds;

[0026] 2) The C2 value of the non-serving cell is greater than the C2 value of the serving cell...

Abstract

The invention discloses a method for improving success ratio of an originating call of a mobile terminal. The method calculates the quality of a service cell by receiving data of a paging channel; the process of random access request is carried out after the mobile terminal starts service request; when the random access request fails, the quality of the service cell is judged whether meets the request, and if not, that whether the neighbor cells are selectable is judged and when the cells are selected again, the random access request is started again. By adopting the method of the invention, the success ratio of the originating call can be improved effectively.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for improving the success rate of a call initiated by a mobile terminal. Background technique [0002] With the development of society, people communicate more frequently in their work and life. At the same time, people's requirements for communication and communication systems are getting higher and higher. The existing GSM mobile communication system is a micro-cellular structure. Users often change locations when using mobile terminals. As the user's location changes, it will inevitably lead to changes in the service cell of the mobile terminal. The change of the serving cell of the mobile terminal is usually accompanied by the cell reselection process. Usually, when there is an adjacent serving cell with a stronger signal, or when the DSC (Downlink Signaling Failure Counter) of the current serving cell is 0, cell reselection is required. . [0003] Before cell ...
