Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
In the embodiment of the present invention, UE can include mobile UE or fixing UE, and corresponding mobile network is with fixing
Two kinds of network architectures of network, do not limit this patent of the present invention.
Embodiments provide a kind of method processing separation, as it is shown in figure 1, described method can be wrapped
Include following steps:
101, S-GW knows that MME instruction separates UE.
MME instruction S-GW separates UE can various ways.Such as when UE Jin Cunyige Packet Data Network
(Packet Data Network, PDN) connect time, MME send delete user conversation message to S-GW,
Then represent that MME instruction S-GW separates UE, more such as MME carries mark in deleting user conversation message, comes
Instruction separates UE.Concrete instruction separates the mode embodiment of the present invention of UE and is not construed as limiting.
If 102 first timer time-out, S-GW separates this UE.
After gateway learns that MME instruction separates UE, it is judged that first timer time-out, and then separate use
Family equipment, wherein, this first timer is positioned on S-GW, carries out for UE is in the duration of Idle state
Timing, i.e. when UE transfers Idle state to from connected state, this first timer reset start timing, when UE from
When Idle state transfers connected state to, this first timer stops timing.The state of first timer can be divided into time-out
State and have not timed out state.Setting duration it is provided with, when the timing duration of first timer on first timer
When exceeding setting duration, first timer is in timeout mode.The setting duration of first timer is more than on UE
The setting duration of periodical position renewing timer, concrete numerical value can be by operator according to concrete network condition
It is set.The SR part sent due to UE is forwarded to MME process by S-GW, and part is by S-GW voluntarily
Process, so the first timer on S-GW can keep same with the periodical position renewing timer on UE
Step.
Periodical position renewing timer in prior art, when UE is transferred to Idle state by connected state, on UE
Start up to intervalometer with the movement on MME simultaneously.When UE initiates connection request again, such as UE has
Data to be transmitted, and under S1_Relay framework, part SR, by S-GW process, is no longer forwarded to MME.
Therefore, MME cannot learn that UE is transferred to connection status by idle condition the most, so movement cannot be terminated can
Reach intervalometer.When S-GW has processed this SR, UE is returned to idle condition, restarts periodic location
Update intervalometer.Due to the starting early than the periodic location update restarted up to intervalometer of the movement on MME
Intervalometer, therefore when moving up to timer expiry, periodical position renewing timer not time-out,
UE will not initiate periodic location update, by mistake, MME thinks that UE is unreachable, and then starts implicit detach
Intervalometer.If before the implicit detach timer expiry on MME, UE is fixed due to periodic location update
Time device be not timed-out and never initiate periodic location update or other connection building process, then work as MME
On implicit detach timer expiry time, MME will separate UE mistakenly.
What the embodiment of the present invention provided processes the method separated, by being provided for user on gateway
Equipment is in Idle state duration and carries out the first timer of timing, owing to the SR of subscriber equipment transmission is by service network
Close and forward or process, so first timer can be protected with the periodical position renewing timer on subscriber equipment
Hold synchronization, therefore can properly separate subscriber equipment according to the state of this first timer, it is to avoid mobility pipe
The mistake separation to subscriber equipment of the reason network element.
The embodiment of the present invention additionally provides a kind of method processing separation, as in figure 2 it is shown, described method includes
Following steps:
201, MME instruction S-GW separates UE.
When, after the implicit detach timer expiry on MME, MME can send instruction message to S-GW, instruction
S-GW separates UE.Such as MME transmission deletion user conversation message is to S-GW, and this deletion user conversation message is taken
Tape identification, in order to indicate S-GW to separate UE, more such as when UE Jin Cunyige Packet Data Network's connection, MME
Send deletion user conversation message and separate UE to S-GW, instruction S-GW.In prior art, MME is provided with
Mobile up to intervalometer and implicit detach intervalometer, when implicit detach timer expiry, MME indicates S-GW
Separate UE；In embodiments of the present invention, MME is upper can also only arrange implicit detach intervalometer, and this implicit expression is divided
The duration that sets from intervalometer is more than the setting duration of the periodical position renewing timer on UE, and permissible
More than the setting duration of the first timer on S-GW, when UE is transferred to Idle state by connected state, MME starts
Implicit detach intervalometer, when implicit expression timer expiry, MME instruction S-GW separates UE.
202, S-GW judges that first timer is the most overtime.
S-GW knows that MME instruction separates after UE, it is judged that first timer is the most overtime, and wherein, this is first fixed
Time device be positioned on S-GW, for when subscriber equipment transfers Idle state to from connected state start, UE is in sky
The duration of not busy state carries out timing, and i.e. when UE transfers Idle state to from connected state, this first timer resets and starts
Timing, when UE transfers connected state to from Idle state, this first timer stops timing.This first timer
State is divided into timeout mode and has not timed out state.Setting duration it is provided with, when first is fixed on this first timer
Time device timing duration when exceeding the setting duration of first timer, this first timer is in timeout mode,
The duration that sets of this first timer is more than the setting duration of periodical position renewing timer on UE, specifically counts
Value can be set according to concrete network condition by operator.
If first timer is overtime, perform 203, if first timer has not timed out, perform 204.
203, S-GW separates UE.
First timer time-out represents that the time that UE transfers Idle state to from connected state has been over first timer
Setting duration, it is believed that what MME separated UE is designated as correct separation instruction, now UE from
Net, needs to be separated.
204, S-GW stops separating UE.
First timer has not timed out expression UE and transfers the time of Idle state to also not less than first timer from connected state
Setting duration, it is believed that MME separate UE be designated as mistake separation instruction, now UE not from
Net, it is not necessary to separated, therefore UE is not separated by S-GW stopping separation UE, i.e. S-GW.
In 203, the implicit detach intervalometer of mobile management network element and the first timer of gateway are same
Time be in timeout mode after, UE will be immediately disconnected.The follow-up connection may still can initiated with network side of UE, vertical
I.e. separate UE and be unfavorable for that UE recovers the connection with network side, therefore can be according to network condition and actual fortune
Battalion's experience sets one section of buffering duration, to realize postponing to separate UE.
As a kind of example, can realize postponing to separate UE by setting default off-network duration, preset off-network
Duration is equal to buffering duration.As it is shown on figure 3, after 202, if first timer is overtime, perform step 2021.
2021, S-GW judges whether the actual off-network duration of UE exceedes default off-network duration.
A length of during the actual off-network of UE learn mobile management network element from first timer time-out to gateway
Instruction separates the time span between described subscriber equipment.
If the actual off-network duration of UE exceedes default off-network duration, then perform step 203；If the reality of UE from
Net duration not less than default off-network duration, then performs step 204.
Wherein, the actual off-network duration of UE exceedes default off-network duration and represents that UE is after first timer time-out
The connection with network side is not the most initiated, it is believed that UE off-network, MME separates UE in buffering duration
Be designated as correct separation instruction, UE needs to be separated.The actual off-network duration of UE is not less than default off-network
Duration represents that UE yet suffers from certain buffering duration after first timer time-out, it is not necessary to be immediately disconnected UE,
It is believed that MME separates the separation instruction being designated as mistake of UE.
As a kind of example, it is also possible to realize postponing to separate UE by setting second timer.Wherein,
Two intervalometers are positioned on S-GW.Similar with first timer, due to UE part SR by S-GW voluntarily
Reason, another part is forwarded to MME process by S-GW, and S-GW can accurately know the transformation of UE connection status.
Second timer starts when first timer time-out, for keeping UE after first timer time-out
The duration of Idle state carries out timing, and i.e. for after first timer time-out, the connection status of UE does not occur
Change is still within this section of duration of Idle state and carries out timing.During first timer time-out, second timer is clear
Zero starts timing, and when UE transfers connected state to from Idle state, second timer stops timing.Second timer
State can be divided into timeout mode and have not timed out state.Preset duration it is provided with on second timer, wherein,
The preset duration of second timer is equal to buffering duration, when the timing duration of second timer is more than the second timing
During preset duration on device, second timer is in timeout mode, when the timing duration of second timer does not surpasses
When crossing the preset duration on second timer, second timer is in the state of having not timed out.As shown in Figure 4, exist
After 202, if first timer is overtime, perform step 2022.
2022, S-GW judges that second timer is the most overtime.
If second timer is overtime, then performs step 203, if second timer has not timed out, then perform step
204。
Wherein, second timer time-out does not still have in representing UE buffering duration after first timer time-out
Originating from the connection of network side, it is believed that UE off-network, MME separation UE is designated as correct separation
Instruction, UE needs to be separated；Second timer has not timed out expression UE and yet suffers from after first timer time-out
Certain buffering duration, it is not necessary to be immediately disconnected UE, it is believed that MME separates the separation being designated as mistake of UE
Instruction.
If additionally, within the time that UE is in Idle state, MME does not indicate S-GW to separate UE, when second
During timer expiry, S-GW also can carry out separating the operation of UE voluntarily, it is not necessary to waits the separation UE's of MME
Instruction.
In step 203, S-GW separates UE can also multiple implementation.
As a kind of example, S-GW can notify that subscriber equipment is initiated subscriber equipment and divided by mobile management network element
The separation for UE is realized, as shown in Figure 5 from flow process:
301, S-GW transmission separate user equipment indicates to MME.
S-GW is judged by the method as shown in Fig. 2, Fig. 3 or Fig. 4, it is judged that user to be separated sets
Time standby, send separate user equipment instruction to MME, instruction MME separate user equipment.Such as gateway is sent out
Send separation request message (Detach Request) to MME, this separation request message carries use to be separated
Family device identification, it is also possible to carry the reason causing subscriber equipment to separate.
302, MME initiates subscriber equipment separation process.
After MME receives the deletion conversational response that S-GW sends, initiate subscriber equipment separation process.As one
Example, initiating subscriber equipment separation process can be: MME transmission deletion conversation request to S-GW；S-GW sends out
Send deletion conversation request to P-GW；P-GW notice PCRF deletes user session information；P-GW sends and deletes meeting
Words respond to S-GW；S-GW sends and deletes conversational response to MME.If the signaling reduction (Idle under idle pulley
Mode signalling reduction, ISR) mechanism is active, and MME also needs to notify service GPRS
Support that node (Serving GPRS Support Node, SGSN) initiates subscriber equipment separation process.
As a kind of example, S-GW can also send deletion user conversation and ask to packet data network gateway
(Packet Data Network Gateway, P-GW), so that P-GW notification strategy and charging rule functions
Entity (Policy and Charging Rules Function, PCRF) deletes the session letter of subscriber equipment
Breath, and the carrying information of S-GW notice MME deletion UE, realize the separation for UE.Such as Fig. 6 institute
Show:
401, S-GW sends and deletes conversation request to P-GW.
S-GW sends and comprises session identification to be deleted to the deletion conversation request message of P-GW, this meeting to be deleted
Words mark indicates all bearing resources of this session to be deleted to be released and the session letter of this session to be deleted
Breath will be deleted.If P-GW have subscribed the positional information of UE, S-GW also need to be in this deletion conversation request
Carry the positional information of UE.If the time zone at UE place changes, also need to carry the time-zone information of UE
In this deletion conversation request.
402, P-GW sends and deletes conversational response to S-GW.
403, P-GW notice PCRF deletes the session information of UE.
404, S-GW transmission deleting bearing is asked to MME.
The deleting bearing request that S-GW sends is carried carrying mark to be deleted and deletes the ginsengs such as cause value
Number.After all of bearing resource of subscriber equipment is released, MME deletes the contextual information of this subscriber equipment.
405, MME transmission deleting bearing responds to S-GW.
So far, UE separates complete.If subscriber equipment is registered at SGSN also simultaneously, then S-GW also needs notice
SGSN deletes the carrying information of UE.
As a kind of example, UE can also directly be separated by S-GW.Such as S-GW receives MME and sends
Deletion conversation request after, it is judged that need to separate UE, S-GW and send and delete conversation request to P-GW；P-GW
Notice PCRF deletes the session information of UE；P-GW sends and deletes conversational response to S-GW；S-GW sends deletion
Conversational response is to MME.If ISR mechanism is active, MME also needs to notify that SGSN initiates user and sets
Standby separation process.
After the S-GW of step 204 stops separating UE, further, S-GW can also notify that MME is one
Fix time to indicate again after being spaced and separate described subscriber equipment.Wherein, intervals can be hidden on MME
The setting duration of formula separation intervalometer, it is also possible to be that the implicit detach intervalometer setting duration on MME deducts UE
The last free time length, free time length the last for UE obtains to S-GW for transferring idle condition to from UE
Know that MME instruction separates the time span between UE, it is also possible to be other duration values.
As a kind of example, S-GW notice MME indicates separation UE can pass through weight the most again
The implicit detach intervalometer opening MME realizes, as shown in Figure 7:
501, MME sends and deletes conversation request to S-GW.
Implicit detach timer expiry on MME, sends and deletes conversation request to S-GW, instruction S-GW separation
Subscriber equipment, wherein, carries the identification information of session to be deleted in this deletion conversation request.
502, S-GW sends and deletes conversational response to MME.
S-GW is judged by the method as shown in Fig. 2, Fig. 3 or Fig. 4, it is judged that stop separating user
During equipment, transmission deletion conversational response to MME.
This deletion conversational response can be carried refusal and be separated instruction, and this refusal separates instruction and is used for representing that S-GW refuses
Separate absolutely UE；It can be on MME that this deletion conversational response can also carry duration value, such as this duration value
Implicit detach intervalometer sets duration and deducts the last free time length of UE, it is also possible to be fixing duration,
Wherein, the last for UE free time length learns MME instruction point for transferring idle condition to from UE to S-GW
Time span between UE.
503, MME restarts implicit detach intervalometer.
After MME receives the deletion conversational response that S-GW sends, if this deletion conversational response carries refusal point
From instruction, MME retains the contextual information of UE, i.e. keeps UE login state in a network, and MME
Restarting implicit detach intervalometer, after the implicit detach timer expiry of MME, MME will send out to S-GW again
Deletion user conversation request is sent to indicate S-GW to separate UE；If this deletion conversational response carries duration value,
The setting duration of implicit detach intervalometer, before restarting implicit detach intervalometer, is modified by MME, amendment
For deleting the duration value carried in conversational response.
It is emphasized that processes in the method separated due to what the embodiment of the present invention provided, and S-GW is upper newly-increased
Intervalometer, so paging way and step to UE are also compared with technology difference, detailed process is as follows:
Before implicit detach intervalometer starts but has not timed out, as MME paging UE, the trigger event of paging
Can include but are not limited to: UE registers with circuit domain in packet domain simultaneously, and MME is from circuit domain mobile switch
Center (Mobile Switching Center, MSC) receives calling user instruction；Or MME receives ownership
The delete position informational message that client server (Home Subscriber Sever, HSS) sends, and its
In deletion type be set to user contracting data and abandon.
MME sends the S-GW that beep-page message adheres to UE, carries the mark of UE, paging in this beep-page message
The parameters such as Location Area Identification.
Whether S-GW forwards beep-page message to target radio base station based on UE Determines.
For the UE of Idle state, after S-GW receives the beep-page message that MME sends, its processing scheme is the most permissible
Including:
1) having not timed out when the first timer on S-GW, S-GW forwards beep-page message to target radio base station.Choosing
Select target radio base station mode can but be not limited only to as based on paging Location Area Identification, or based on paging
Target radio base station IP address in message.
S-GW arranges page response intervalometer for paged UE after forwarding beep-page message, fixed at this page response
Time device time-out before, when UE transfers connected state to from Idle state, S-GW need notify MME process.
2) when the first timer time-out on S-GW, S-GW directly replys paging refuse information (Paging
Reject) MME is given.This paging refuse information includes type of message, ID and cause value.Due to
One timer expiry and the paging failure that causes, the cause value in paging refuse information may be configured as user can not
Reach.If additionally, S-GW receives sends the downlink data packet to UE, the most not retransmiting downlink data notification
Message is to MME.If the dedicated bearing that S-GW receives P-GW transmission sets up the control such as message or dedicated bearing amendment
Face processed message, is also not longer notified about MME, and directly replys refuse information to P-GW.MME receives paging refusal and disappears
After breath, find that user is unreachable, follow-up will not retransmit beep-page message.
What the embodiment of the present invention provided processes the method separated, by being provided for user on gateway
Equipment is in Idle state duration and carries out the first timer of timing, owing to the SR of subscriber equipment transmission is by service network
Close and forward or process, so first timer can be protected with the periodical position renewing timer on subscriber equipment
Hold synchronization, therefore can properly separate subscriber equipment according to the state of this first timer, it is to avoid mobility pipe
The mistake separation to subscriber equipment of the reason network element.
The embodiment of the present invention also provides for a kind of method processing separation, as shown in Figure 8, described method include as
Lower step:
601, when UE is transferred to idle condition by connection status, S-GW starts first timer.
Wherein, this first timer is positioned on S-GW, for when subscriber equipment transfers Idle state to from connected state
Starting, the duration that UE is in Idle state carries out timing, i.e. when UE transfers Idle state to from connected state, and should
