Description
Technical field
The embodiment of the present invention is related to field of communication technology more particularly to a kind of paging method and MME device.
Background technique
Paging (Paging) process is in LTE system when user is in idle condition, and network has signaling or data needs
When being handed down to user, MME (Mobility Management Entity, mobility management entity) needs to look for by paging process
After switching to connection status to user and by User Status, signaling or data could be sent to user.Paging has certain paging
Range, including MME record nearest cell, nearest eNodeB (Evolved Node B, evolved Node B), adjacent eNodeB,
Nearest TA (Tracking Area, tracking area), TAList (Tracking Area list, tracking area list).Paging range is got over
Greatly, a possibility that successful page is to user is bigger, but since the capacity of radio call channel is limited, paging range is bigger
It is bigger to will also result in radio call load.Therefore the prior art is carried out by the way of generally being paged using classification, successively according to from
Small to be paged to big paging range, if last time paging is failed, next time expands paging range.For example it may be configured as three-level
Paging, paging is cell range for the first time, if unsuccessful be changed to eNodeB range for the second time, if also unsuccessful be changed to TA model
It encloses.
Existing paging hierarchical policy takes all users using identical paging hierarchical policy on MME, if paging point
Paging classification is more in grade strategy, initial Page range is smaller, for the user of high-speed mobile, due to the model of initial Page
Enclose small, user will soon move and go beyond the scope, this will lead to initial paging failure several times, until paging range gradually expands
It is big to a certain degree after could page and arrive the user.And if the initial Page range paged in hierarchical policy is larger, will increase
The paging load of network causes the waste of paging resource.

Target cell is set as the mobile class Target cell of low speed.Therefore, the mobile speed of the corresponding user of mobility classification of Target cell
Target cell can be divided by degree：It is small that ultrahigh speed moves the mobile class target of class Target cell, high-speed mobile class Target cell, middling speed
Area, the mobile class Target cell of low speed, the mobile class Target cell of Ultra-Low Speed etc..It is detailed, if Target cell where active user is
The mobile mobile class of ultrahigh speed, then page classification and be set as TAList；If Target cell where active user is high-speed mobile class,
Paging classification may be configured as TA, TAList；If Target cell where active user is the mobile class of middling speed, it is settable to page classification
For adjacent eNodeB, TA, TAList；If Target cell where active user is the mobile class of low speed, paging classification be may be configured as
ENodeB, adjacent eNodeB, TA, TAList；If Target cell where active user is the mobile class of extremely low speed, paging classification can
It is set as cell, eNodeB, adjacent eNodeB, TA, TAList；And so on.In addition, paging classification can also be arranged including family
The smaller region such as front yard base station.
In addition, this method further includes before the mobility classification of MME device acquisition Target cell：MME device is according to target
Movement speed in cell more than the user of number of users threshold number determines the mobility classification of Target cell.
103, MME device determines that used paging classification is joined when paging to predesignated subscriber according to mobility classification
Number, paging value parameter include：Paging number, the range paged every time, paging waiting time；Wherein, different mobility class
Different paging value parameters is not corresponded to.
It should be noted that the movement speed of the corresponding user of mobility classification of Target cell is corresponding with Target cell
Paging range is directly proportional.
In addition, MME device determines used paging classification ginseng when paging to predesignated subscriber according to mobility classification
Before number, further include：Corresponding paging classification ginseng is arranged according to the mobility classification of Target cell for Target cell in MME device
Number.
104, MME device pages predesignated subscriber according to paging value parameter.
Illustratively, when MME device, which determines, to be needed to initiate paging to the predesignated subscriber in Idle state, this is first looked at
The Target cell that user's the last time occurs, it is right according to the mobility classification of the Target cell and corresponding paging value parameter
User carries out corresponding range paging and classification paging.
In above method embodiment, when MME device determines that needs initiate paging to the predesignated subscriber in Idle state first,
The mobility classification of predesignated subscriber's last time is obtained where when being in connected state Target cell and Target cell；And according to
Mobility classification determination used paging value parameter when being paged to predesignated subscriber；Then it is sought according to paging value parameter
Exhale predesignated subscriber；Wherein, paging value parameter includes：Paging number, the range paged every time, paging waiting time.Above-mentioned
In embodiment of the method to mobility classification and how to carry out classification paging carried out illustrative explanation, which is not described herein again；
