Embodiment 1
[0028] Embodiment one, combine figure 2 Detailed description, figure 2 It is a schematic flow chart of Embodiment 1 of the present invention.
[0029] Step 201: The MME receives a downlink data notification message from a certain UE.
[0030] When the MME receives the downlink data notification message, it indicates that a paging message needs to be sent to the eNB.
[0031] Step 202: The MME judges whether all the TAs covered by the eNB that needs to receive the paging message belong to the TA list registered by the terminal.
[0032] The MME first judges whether all the TAs covered by the eNB that needs to receive the paging message belong to the TA list registered by the terminal, and then decides which TA's TAIs to carry in the paging message or not to carry any TA's TAI. The TA list is obtained by querying the saved UE registration information.
[0033] The TA information covered by all eNBs connected to the MME itself can be pre-recorded on the information table, a...
Embodiment 2
[0038] Embodiment two, combine image 3 Specifically, image 3 It is a schematic flow diagram of Embodiment 2 of the present invention
[0039] Step 301: The MME receives a downlink data notification message from a certain UE.
[0040] When the MME receives the downlink data notification message, it indicates that a paging message needs to be sent to the eNB.
[0041] Step 302: The MME judges whether all the TAs covered by the eNB that needs to receive the paging message belong to the TA list, if yes, go to step 303, otherwise go to step 305.
[0042]The TA information covered by the eNB connected to the MME can be pre-recorded on the information table, and the TA list can be obtained by querying the saved UE registration information; Whether all the TAIs of the TAs covered by the eNB in the message belong to the TA list registered by the UE, if yes, go to step 303 ; otherwise, go to step 305 .
[0043] The information table may be configured on the MME, or on other enti...
Embodiment 3
[0055] Embodiment three, combine Figure 4 Specifically, Figure 4 It is a schematic flow chart of Embodiment 3 of the present invention.
[0056] Step 401: The eNB receives the paging response message sent by the UE.
[0057] The UE sends a paging response message to the eNB to which it belongs.
[0058] Step 402: The eNB receiving the paging response message selects other eNBs that need to send the paging cancel message according to the eNB information.
[0059] The evolved base station information includes the evolved base station information under all the tracking areas covered by the mobility management entity to which it belongs and the tracking area list registered by the terminal; the evolved base station information under all the tracking areas covered by the mobility management entity to which it belongs can be preset It is configured on the eNB; and when the MME sends a paging message, the eNB saves the TA list registered by the UE carried in the paging message. ...
