Embodiment 1

[0034] When the MME paging the mobile terminal UE1 due to other mobile terminals initiating a call to the mobile terminal UE1 or due to the needs of other service processes, firstly, from the message or signaling in the last service-related record saved before, for example, from the E-UTRAN CGI in "PATH SWITCH REQUEST" or "INITIAL UEMESSAGE" to know the serving cell information of the latest service of UE1.

[0035] Please refer to the attached figure 2 , eNB1 is the serving cell of the mobile terminal UE1 that provided services for the mobile terminal last time, and the MME sends a paging message Request-Msg to eNB1 through the S1 interface after learning the serving cell eNB1 of the mobile terminal that provided services for the mobile terminal last time;

[0036] After receiving the paging message Request-Msg, eNB1 sends a paging response message Response-Msg corresponding to the paging message Request-Msg to the MME when it determines that UE1 is within the coverage area ...

Embodiment 2

[0041] The process for the MME to determine the serving cell of the UE1 that provided the service for the mobile terminal last time is similar to the first embodiment, and will not be described in detail here.

[0042] Please refer to attached image 3 Compared with Embodiment 1, in order to improve the success rate of paging, the MME can send the latest mobile terminal to UE1 according to the fact that the distance between the current location of the mobile terminal and the location of the latest service is relatively short. The serving cell eNB1 where the terminal provides services and the adjacent cells eNB2, eNB3 and eNB4 of eNB1 all send paging messages Request-Msg. When sending the above paging messages, in order to reduce the load pressure on the X1 interface and the air interface, you can use the S1 interface to send eNB1, eNB2, eNB3 and eNB4 send paging messages.

[0043] After each cell of eNB1, eNB2, eNB3 and eNB4 receives the paging message Request-Msg, it judges ...

Abstract

The invention discloses a paging method and a paging device, aiming to solve the problems of complex treatment process and larger implementation difficulty in the existing paging technology for determining a fixed zone. The method includes: sending a paging message to a serving cell lately providing services for a mobile terminal; determining that the mobile terminal is paged when a paging response message sent by the serving cell is received; and sending the paging message to all the cells within a tracking area range corresponding to the mobile terminal when no paging response message sent by the serving cell is received.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a paging method and a paging device. Background technique [0002] The process by which a network device searches for a mobile terminal through a paging channel is called a paging process. Currently, in a wireless communication network, each mobile terminal corresponds to at least one tracking area (TA, Tracking Area), and the identifier of the tracking area corresponding to the mobile terminal is stored in the tracking area list corresponding to the mobile terminal. The number of tracking areas corresponding to the mobile terminal is set by the mobile management entity (MME, Mobile Management Entity) or other core network element equipment according to the past mobility of the mobile terminal. For example, if the mobile terminal has low mobility or basically does not move, the mobile terminal can only correspond to one tracking area, and the tracking area list co...
