Problems solved by technology
Because the access network cannot judge whether the terminal has received a paging response under the existing structure, the retransmission of the access network is for all paging messages. The maximum number of paging users per unit time is inversely proportional, which will lead to a double decrease in network paging capacity, thus greatly wasting the public channel resources of the network
[0006] There are relatively serious defects in the existing methods for dealing with the problem of monitoring the paging indication and the paging channel for an excessively long time, so a method for monitoring the paging indication and the paging channel is needed, which is used to improve the call quality during cell reselection. Connect rate, reduce access delay and do not affect network paging capacity

Embodiment Construction
[0022] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0023] Under the existing protocol structure, the system information delivered by the network broadcasts the adjacent cells of this cell, and their corresponding frequency points and scrambling codes. In actual networking, common channel configurations in an area are likely to be the same, for example, basically the same common channel configuration is adopted in current networks. The method adopted in the present invention is to indicate whether the adjacent cell and the current serving cell adopt the same common channel configuration except for the frequency point and the scrambling code by adding the common channel configuration indication in the system information. ...

The invention provides a method, a system and a terminal for monitoring a paging indicator and a paging channel. The method comprises the following steps: a terminal judges whether the terminal is in the cell reselection process or not; the terminal receives a neighbor cell list which contains indication information of configuration of a common channel of neighbor cells and is sent by a base station of a service cell if the terminal judges that the terminal is in the cell reselection process, wherein the indication information of the configuration of the common channel is used for indicating whether the configuration of the common channel of the neighbor cells and the service cell is the same or not; and the terminal selects a target cell from the neighbor cell list and monitors the paging indicator and the paging channel of the target cell according to the configuration of the common channel of the service cell when the indication information of the configuration of the common channel indicates that the configuration of the common channel of the target cell and the service cell is the same. The method can greatly reduce the time which can not receive paging during the cell reselection, reduce the probability of paging loss caused by the cell reselection and further improve the completion ratio of the system.
Description
technical field [0001] The present invention relates to the field of mobile communication, and in particular, the present invention relates to a method, a system and a terminal for monitoring a paging indication and a paging channel. Background technique [0002] The TD-SCDMA system is one of the current research hotspots in mobile communications. The goal of the system is to seamlessly and reliably provide users with various efficient and diverse services anytime and anywhere in different environments, so as to meet the needs of current and future people for communication services. demand. In mobile communications, user terminals will frequently face cell switching, which triggers cell reselection. In the current TD-SCDMA network, when the user terminal performs cell reselection, especially when the frequency of the target cell and the serving cell are different, it must read the system information before it can monitor the paging indication and paging channel and receive...
