Description
Technical field
The present invention relates to the communication technology more particularly to a kind of intelligent paging methods and intelligent paging equipment.
Background technique
Paging (Paging) is the distinctive mechanism of mobile network, for finding and waking up the user in idle (idle) state
Terminal (UE, User Equipment).Here idle state is for connected state.User terminal is being commenced business
When (for example make a phone call, browse webpage, carry out File Transfer Protocol downloading), wireless network can be corresponding empty for user terminal distribution
Mouth resource is for user terminal sending and receiving data, and user terminal is in connected state at this time.But the interface-free resources of wireless network and use
The electricity of family terminal is all limited, when the user terminal in connected state is more than certain time not use data service (one
As be 10 seconds), network can actively be released to user terminal distribution interface-free resources, allow user terminal to enter idle state, with
It reduces the consumption of interface-free resources and saves user terminal electricity.
To which unless user terminal is carrying out related service, otherwise, user terminal can be all in idle condition, i.e., wirelessly
Interface-free resources are unappropriated state.After user terminal enters idle state, network side issue audio call or under
Row data packet just can not directly be sent to user terminal, it is necessary to terminal be waken up the company of reverting to from idle state by paging mechanism
Connecing state can just commence business later.
The network equipment is referred to as paging by the process that paging channel finds user terminal.At present in wireless communication networks
In network, each user terminal corresponds at least one tracking area (TA, Tracking Area), tracking corresponding to user terminal
The mark in area is stored in the tracking area list (TA List) of the corresponding user terminal, the number of the corresponding tracking area of user terminal
Amount is by mobile management entity (MME, Mobile Management Entity) or other core network element equipment according to the user
The previous mobile implementations of terminal and be arranged.For example, if the mobility of user terminal is lower or do not move substantially, the user
Terminal can only correspond to a tracking area, to only include the mark of a tracking area in the corresponding tracking area list of the user terminal
Know；If the mobility of user terminal is higher, it may include multiple tracking areas in the corresponding tracking area list of the user terminal
Mark.
Existing paging scheme is, when user terminal has downlink data industry by other users terminal call or user terminal
When business, MME is according to the mark of the tracking area for including in the tracking area list of the user terminal, into the region of corresponding tracking area
All cells send paging message, i.e., to all user terminals, all business use unified paging domain.
Existing paging technique has the following problems:
When MME pages user terminal, paging domain is TA or TA List, is adopted to all business of all users
With unified paging domain, when the cell for including in paging domain is more, the downlink expense for sending paging message is larger, but pages
The frequency of area update can be relatively low, so that the overhead that paging domain renewal process needs is smaller；Correspondingly, paging zone
When the cell for including in domain is less, the downlink expense for sending paging message generation is smaller, but the frequency that paging domain updates is opposite
It is higher, so that the overhead that paging domain renewal process needs is also higher.Therefore, long term evolution (LTE, Long Term
Evolution) system or the second generation (2G, 2Generation), the setting paging of the third generation (3G, 3Generation) communication system
When region, is usually updated in paging expense and paging domain and obtain reasonable compromise between expense.
Paging message can occupy the paging resource of core net MME and evolved base station (eNB, evolved NodeB), seek
When exhaling region larger, the probability for finding user terminal is relatively high, but the paging resource consumed is also more；Paging domain is smaller
When, the probability for finding user terminal is relatively low, and the paging resource consumed is also relatively low.
For example, using the big area paging of TA or TA List for the not strong user terminal of mobility, a large amount of paging is consumed
Resource；The user terminal strong for mobility is sought if paged using the nearest persistent district of user terminal and adjacent area zonule
It exhales successful probability lower, influences user experience；For there is certain ambulant user terminal, if not distinguishing event category,
And the big area paging of TA or TA List is used, still result in the waste of paging resource；For distinguishing user terminal mobile behavior
Characteristic, when being used uniformly the paging by class of service progress different zones, if carrying out zonule paging will lead to mobility
Strong user terminal paging failure, if the user terminal not strong to mobility, which carries out big area paging, will lead to paging resource wave
Take.
In conclusion in the related technology, under the premise of to user terminal paging successfully, how to ensure that paging is not caused to provide
The waste in source, there is no effective solution.
