Method for enabling terminal to be paged in time and terminal

Abstract

The invention discloses a method for enabling a terminal to be paged in time and a terminal. The method is applied to the circumstance that the terminal carries out a cell re-selection process of crossing location areas or routing areas or tracking areas, or the terminal switches voice of crossing location areas or routing areas or tracking areas, then is in an on-hook state, and then carries out a cell selection process in a target cell. The method comprises the step of: reading a system broadcast message by a mobile terminal, wherein the read system broadcast message comprises required information used for initiating a location area updating process or required information used for initiating a routing area updating process or required information used for initiating a tracking area updating process; and initiating the location area updating process, the routing area updating process or the routing area updating process. By utilizing the method and the terminal, the time that the terminal cannot be paged can be shortened and the terminal can be paged in time.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and a terminal for enabling a terminal to be paged in time. Background technique [0002] An important feature of the wireless mobile communication system is that the terminal can move freely within the coverage of the system, and cell reselection is to ensure that the terminal can reside in the most suitable cell in the network during the mobile process in the wireless mobile communication system. An important function of the success rate of business calls. There are two types of cell reselection: intra-system and inter-system cell reselection, and intra-system cell reselection can be further divided into intra-carrier and inter-carrier cell reselection. The premise of cell reselection is to trigger the measurement of neighboring cells and judge the measurement results. On the premise that the reselection criterion is met, the terminal performs the process...

Problems solved by technology

[0027] Since the current 2G system and the 3G system use different location area settings, when the mobile terminal interoperates between the 2G system and the 3G system, each reselection or handover between systems will trigger a location area update and routing area update , and the terminal cannot be paged by the CS domain until the update of the location area during the reselection process is completed, and cannot be paged by the PS domain before the completion of the routing area update during the reselection process

In the early stage of 3G network construction, in areas where 2G and 3G interoperability is relatively frequent, the long reselection delay between systems has a great impact on the network connection rate

In July 2009, in the third-party test organized by China Mobile, 43.27% of the voice failures were caused by the fact that the location area of ​​the terminal was not updated in time during the cell reselection process, which made the terminal unable to be paged.

[0028] In addition, when intra-system or inter-system cell reselection across location areas or cross-routing areas or cross-tracking areas is performed in the latter three-generation mobile communication (B3G) system and the fourth-generation mobile communication (4G) system, and when the terminal performs cross-location area, cross-routing area, or cross-tracking area voice handover, and in the process of cell selection for target cells in the 2G system, 3G system, B3G system, and 4G system, there are also cases where the terminal does not perform location area update or routing. The problem of not being able to be paged before zone update or tracking zone update
