Embodiment
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 clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
In the embodiment of the present invention, UE can include mobile UE or fixed UE, corresponding mobile network and solid
Determine two kinds of network architectures of network, this patent of the present invention is not limited.
The embodiments of the invention provide a kind of method for handling separation, as shown in Fig. 1, methods described may include steps of：
1 01, S-GW knows that MME indicates separation UE.
Beautiful E indicates that S-GW separation UE can have various ways.For example as UE Jin Cunyige Packet Data Networks (Packe t Da t a Ne twork, when PDN) connecting, MME, which is sent, deletes user conversation message to S-GW, then represent that beautiful E indicates S-GW separation UE, for example beautiful E carries mark in user conversation message is deleted again, to indicate to separate UE.The specific mode embodiment of the present invention for indicating separation UE is not construed as limiting.
If 1 02, first timer time-out, S-GW separates the UE.
Gateway learns that beautiful E is indicated after separation UE, judge first timer time-out, and then separate user equipment, wherein, the first timer is located on S-GW, and the duration for being in Idle state to UE carries out timing, i.e. when UE switchs to Idle state from connected state, the first timer, which is reset, starts timing, and when UE switchs to connected state from Idle state, the first timer stops timing.The state of first timer can be divided into timeout mode and have not timed out state.Setting duration is provided with first timer, when the timing duration of first timer exceedes setting duration, first timer is in timeout mode.The setting duration of first timer is more than the setting duration of periodical position renewing timer on UE, and concrete numerical value can be set by operator according to specific network condition.Because the UE SR sent are partly forwarded to MME processing by S-GW, partly voluntarily handled by S-GW, so the first timer on S-GW can keep synchronous with the periodical position renewing timer on UE.
In the prior art, when UE switchs to Idle state by connected state, the periodical position renewing timer on UE starts simultaneously with the movement on beautiful E up to timer.When UE initiates connection request again, such as UE has data to be transmitted, and under S l _ Re l ay frameworks, part SR is no longer forwarded to solid E by S-GW processing.Therefore, beautiful E can not learn that UE has now switched to connection status by idle condition, and then can not terminate mobile up to timer.When S-GW has handled the SR, UE is returned to idle condition, restarts periodical position renewing timer.Due to the movement on beautiful E up to timer startup earlier than the periodical position renewing timer restarted, therefore when mobile reachable timer expiry, periodical position renewing timer does not have time-out, UE will not initiate periodic location update, beautiful E thinks that UE is unreachable by mistake, enters
And start implicit detach timer.If before the implicit detach timer expiry on MME, UE is because periodical position renewing timer is not timed-out and never initiates periodic location update or other connection building process, then when the implicit detach timer expiry on MME, MME will mistakenly separate UE.
The method of processing separation provided in an embodiment of the present invention, by being provided for being in user equipment the first timer that Idle state duration carries out timing on gateway, because the SR that user equipment is sent is forwarded or handled by gateway, so first timer can keep synchronous with the periodical position renewing timer on user equipment, therefore user equipment can be properly separated according to the state of the first timer, it is to avoid mobile management network element is separated to the mistake of user equipment.
The embodiment of the present invention additionally provides a kind of method for handling separation, and as shown in Fig. 2, methods described comprises the following steps：
201st, MME indicates S-GW separation UE.
After implicit detach timer expiry on beautiful E, beautiful E can send instruction message to S-GW, indicate S-GW separation UE.Such as MME, which is sent, deletes user conversation message to S-GW, the deletion user conversation message carries mark, to indicate that S-GW separates UE, then for example when UE Jin Cunyige Packet Data Networks connect, beautiful E, which is sent, deletes user conversation message to S-GW, indicates S-GW separation UE.In the prior art, Gu being provided with mobile reachable timer and implicit detach timer on E, when implicit detach timer expiry, MME indicates S-GW separation UE;In embodiments of the present invention, MME is upper can also only to set implicit detach timer, the setting duration of the implicit detach timer is more than the setting duration of the periodical position renewing timer on UE, and the setting duration of the first timer on S-GW can be more than, when UE switchs to Idle state by connected state, beautiful E starts implicit detach timer, when implicit timer expiry, and MME indicates S-GW separation UE.
202nd, S-GW judges whether first timer is overtime.
S-GW knows that beautiful E is indicated after separation UE, judge whether first timer is overtime, wherein, the first timer is located on S-GW, for starting when user equipment switchs to Idle state from connected state, and the duration that Idle state is in UE carries out timing, i.e. when UE switchs to Idle state from connected state, the first timer, which is reset, starts timing, and when UE switchs to connected state from Idle state, the first timer stops timing.The state of the first timer is divided into timeout mode and has not timed out state.Setting duration is provided with the first timer,
When the timing duration of first timer exceedes the setting duration of first timer, the first timer is in timeout mode, the setting duration of the first timer is more than the setting duration of periodical position renewing timer on UE, and concrete numerical value can be set by operator according to specific network condition.
If first timer is overtime, 203 are performed, if first timer has not timed out, 204 are performed.
203rd, S-GW separates UE.
First timer time-out represents that UE times for switching to Idle state from connected state have been over the setting duration of first timer, it is believed that the beautiful E separation UE correct separation that is designated as indicates, now UE off-network, it is necessary to be separated.
204th, S-GW stops separation UE.
First timer has not timed out expression UE and switchs to the time of Idle state also not less than the setting duration of first timer from connected state, it is considered that the beautiful E separation UE separation for being designated as mistake is indicated, now UE not off-networks, it is not required to be separated, therefore S-GW stoppings separation UE, i.e. S-GW is not separated to UE.
In 203, the implicit detach timer of mobile management network element and the first timer of gateway are in after timeout mode simultaneously, will be immediately disconnected UE.UE subsequently may can still initiate the connection with network side, be immediately disconnected UE and be unfavorable for UE recoveries and the connection of network side, therefore can set one section of Slow according to network condition and actual operation experience and rush duration, to realize delay separation UE.
As a kind of example, delay separation UE can be realized by the default off-network duration of setting, default off-network duration rushes duration equal to Slow.As shown in figure 3, after 202, if first timer is overtime, performing step 2021.
2021st, S-GW judges whether UE actual off-network duration exceedes default off-network duration.
It is a length of during UE actual off-network to learn that mobile management network element indicates the time span the separation user equipment to gateway from first timer time-out.
If UE actual off-network duration exceedes default off-network duration, step 203 is performed;If UE actual off-network duration is not less than default off-network duration, step 204 is performed.
Wherein, UE actual off-network duration exceedes default off-network duration and represents that Slows of the UE after first timer time-out rushes in duration the connection still do not initiated with network side, it is considered that UE off-networks, the beautiful E separation UE correct separation that is designated as indicates that UE needs to be separated.UE actual off-network duration not less than
Default off-network duration represents that UE rushes duration after first timer time-out there are still certain Slow, it is not necessary to be immediately disconnected UE, it is believed that Gu the E separation UE separation for being designated as mistake is indicated.
As a kind of example, delay separation UE can also be realized by setting second timer.Wherein, second timer is located on S-GW.Similar with first timer, because UE part SR is voluntarily handled by S-GW, another part is forwarded to MME processing by S-GW, and S-GW can accurately know the transformation of UE connection status.Second timer starts when first timer is overtime, duration for keeping Idle state after first timer time-out to UE carries out timing, this section of duration progress timing of Idle state is still within for after first timer time-out, UE connection status does not change.When first timer is overtime, second timer, which is reset, starts timing, and when UE switchs to connected state from Idle state, second timer stops timing.The state of second timer can be divided into timeout mode and have not timed out state.Preset duration is provided with second timer, wherein, the preset duration of second timer rushes duration equal to Slow, when the timing duration of second timer exceedes the preset duration on second timer, second timer is in timeout mode, when the timing duration of second timer is not less than preset duration on second timer, second timer is in and has not timed out state.As shown in figure 4, after 202, if first timer is overtime, performing step 2022.
2022nd, S-GW judges whether second timer is overtime.
If second timer is overtime, step 203 is performed, if second timer has not timed out, step is performed
204。
Wherein, second timer time-out represents that Slows of the UE after first timer time-out is rushed in duration and does not still originate from the connection of network side, it is believed that UE off-networks, the MME separation UE correct separation that is designated as indicates that UE needs to be separated；Second timer has not timed out expression UE and rushes duration there are still certain Slow after first timer time-out, it is not necessary to be immediately disconnected UE, it is believed that the beautiful E separation UE separation for being designated as mistake is indicated.
If in addition, being in UE in the time of Idle state, MME does not indicate that S-GW separates UE, and when second timer is overtime, S-GW also can voluntarily carry out separating UE operation, without waiting for beautiful E separation UE instruction.
In step 203, S-GW separation UE can also have a variety of implementations.
As a kind of example, S-GW can notify mobile management network element to initiate user equipment to user equipment
Separation process realizes the separation for UE, as shown in Figure 5：
301st, S-GW sends separate user equipment and indicated to beautiful E.
S-GW is judged by the method as shown in Fig. 2, Fig. 3 or Fig. 4, when judging user equipment to be separated, is sent separate user equipment and is indicated to beautiful E, indicates beautiful E separate user equipments.Such as gateway sends separation request message（De t a ch Reque s t) to MME, customer equipment identification to be separated is carried in the separation request message, can also carry causes the reason for user equipment is separated.
302nd, beautiful E initiates user equipment separation process.
Beautiful E is received after the deletion conversational response of S-GW transmissions, initiates user equipment separation process.As a kind of example, initiating user equipment separation process can be：Beautiful E, which is sent, deletes session request to S-GW;S-GW, which is sent, deletes session request to P-GW;P-GW notifies PCRF to delete user session information；P-GW, which is sent, deletes conversational response to S-GW;S-GW, which is sent, deletes conversational response to beautiful E.If the signaling reduction under idle pulley（Idle mode signalling reduction, ISR) mechanism is active, and MME also needs to notify service GPRS supporting node (Serving GPRS Support Node, SGSN) to initiate user equipment separation process.
It is used as a kind of example, S-GW can also send deletion user conversation and ask to give packet data network gateway (Packet Data Network Gateway, P-GW), so that P-GW notification strategies and charging regulation function entity (Policy and Charging Rules Function, PCRF the session information of user equipment) is deleted, and S-GW notifies solid E to delete UE carrying information, to realize the separation for UE.As shown in Figure 6：
401st, S-GW, which is sent, deletes session request to P-GW.
S-GW is sent into P-GW deletion conversation request message comprising session identification to be deleted, and the session identification to be deleted, which indicates that all bearing resources of the session to be deleted will be translated, to be put and the session information of the session to be deleted will be deleted.If P-GW have subscribed UE positional information, S-GW need to also carry UE positional information in the deletion session request.If the time zone where UE changes, also need to carry UE time-zone information in the deletion session request.
402nd, P-GW, which is sent, deletes conversational response to S-GW.
403rd, P-GW notifies PCRF to delete UE session information.
404th, S-GW sends deleting bearing and asked to MME.
Carrying to be deleted, which is carried, in the deleting bearing request that S-GW is sent identifies and delete the parameters such as cause value.After all bearing resources of user equipment, which are translated, to be put, beautiful E deletes the contextual information of the user equipment.
405th, beautiful E sends deleting bearing and responded to S-GW.
So far, UE separation is finished.If user equipment is also simultaneously in SGSN registrations, S-GW also needs the carrying information for notifying SGSN to delete UE.
As a kind of example, S-GW can also be separated directly to UE.Such as S-GW is received after the deletion session request that solid E is sent, and judges to need to separate UE, S-GW, which is sent, deletes session request to P-GW;P-GW notifies PCRF to delete UE session information；P-GW, which is sent, deletes conversational response to S-GW;S-GW, which is sent, deletes conversational response to solid E.If ISR mechanism is active, beautiful E also needs to notify SGSN to initiate user equipment separation process.
The S-GW of step 204 stops after separation UE, and further, S-GW can also notify solid E to indicate to separate the user equipment after a certain interval again.Wherein, intervals can be the setting duration of implicit detach timer on beautiful E, can also be that implicit detach timer setting duration on beautiful E subtracts the last free time lengths of UE, free time length the last UE is to switch to idle condition from UE to learn that MME indicates the time span separation UE to S-GW, can also be other duration values.
As a kind of example, S-GW notifies MME to indicate that separation UE can be realized by restarting beautiful E implicit detach timer again after a certain interval, as shown in Figure 7：
501st, MME, which is sent, deletes session request to S-GW.
Implicit detach timer expiry on beautiful E, sends and deletes session request to S-GW, indicate S-GW separate user equipments, wherein, the identification information of session to be deleted is carried in the deletion session request.
502nd, S-GW, which is sent, deletes conversational response to MME.
S-GW is judged by the method as shown in Fig. 2, Fig. 3 or Fig. 4, when judging to stop separate user equipment, is sent and is deleted conversational response to beautiful E.
The deletion conversational response can carry refusal separation and indicate, refusal separation indicates to be used for representing S-GW refusal separation UE;The deletion conversational response can also carry duration value, and such as duration value can be that the implicit detach timer setting duration on beautiful E subtracts the last free time lengths of UE or fixation
Duration, wherein, free time length the last UE is to switch to idle condition from UE to learn that beautiful E indicates the time span separation UE to S-GW.
503rd, beautiful E restarts implicit detach timer.
Beautiful E is received after the deletion conversational response of S-GW transmissions, if carrying refusal separation in the deletion conversational response to indicate, Gu E retains UE contextual information, keep the login states of UE in a network, and consolidate E restarts implicit detach timer, after after beautiful E implicit detach timer expiry, beautiful E will send to S-GW and delete user conversation request to indicate that S-GW separates UE again;If carrying duration value in the deletion conversational response, beautiful E modifies before implicit detach timer is restarted to the setting duration of implicit detach timer, is revised as deleting the duration value carried in conversational response.
It is emphasized that due in the method for processing separation provided in an embodiment of the present invention, having increased timer on S-GW newly, so to UE paging way and step also compared with technology difference, under ^ mouthfuls of detailed process：
Before implicit detach timer starts but has not timed out, as beautiful E pagings UE, the trigger event of paging can be included but are not limited to：UE is registered simultaneously in packet domain and circuit domain, and MME receives calling user from circuit domain mobile switching centre (Mob i le Swi tching Center, MSC) and indicated；Or MME receives home subscriber server（Home Subscr iber Sever, HSS) send delete position informational message, and it is therein deletion type be set to user signing Shuo Ju Lost abandon.
Beautiful E sends the parameters such as the mark that UE is carried in the S-GW that beep-page message adheres to UE, the beep-page message, paging position area mark.
Whether S-GW forwards beep-page message to target radio base station based on UE Determines.
For the UE of Idle state, S-GW is received after the beep-page message of MME transmissions, and its processing scheme can for example include：
1) when the first timer on S-GW has not timed out, S-GW forwards beep-page message to target radio base station.The mode of selection target wireless base station can with but be not limited only to be identified based on paging position area, or based on the target radio base station IP address in beep-page message.
It is the UE setting page response timers being paged after S-GW forwarding beep-page messages, before this page response timer expiry, when UE switchs to connected state from Idle state, S-GW needs to notify beautiful E processing.
2) when the first timer time-out on S-GW, S-GW directly replys paging refuse information（Pag ing Rej ec t) give MME.The paging refuse information includes type of message, user's mark and cause value.The paging failure caused by first timer time-out, to may be configured as user unreachable for value the reason in paging refuse information.If sent in addition, S-GW is received to UE downlink data packet, downlink data notification message is not retransmited to beautiful 8.If the dedicated bearing that S-GW receives P-GW transmissions sets up the chain of command message such as message or dedicated bearing modification, MME is also not longer notified about, and directly replys refuse information to P-GW.Beautiful E is received after paging refuse information, it is found that user is unreachable, will not subsequently be retransmited beep-page message.
The method of processing separation provided in an embodiment of the present invention, by being provided for being in user equipment the first timer that Idle state duration carries out timing on gateway, because the SR that user equipment is sent is forwarded or handled by gateway, so first timer can keep synchronous with the periodical position renewing timer on user equipment, therefore user equipment can be properly separated according to the state of the first timer, it is to avoid mobile management network element is separated to the mistake of user equipment.
The embodiment of the present invention also provides a kind of method for handling separation, and as shown in Fig. 8, methods described comprises the following steps：
601st, when UE switchs to idle condition by connection status, S-GW starts first timer.
Wherein, the first timer is located on S-GW, for starting when user equipment switchs to Idle state from connected state, the duration that Idle state is in UE carries out timing, i.e. when UE switchs to Idle state from connected state, the first timer, which is reset, starts timing, and when UE switchs to connected state from Idle state, the first timer stops timing.The state of the first timer is divided into timeout mode and has not timed out state.Setting duration is provided with the first timer, when the timing duration of first timer exceedes the setting duration of first timer, the first timer is in timeout mode, the setting duration of the first timer is more than the setting duration of periodical position renewing timer on UE, and concrete numerical value can be set by operator according to specific network condition.
602nd, when first timer is overtime, S-GW starts second timer.
Wherein, second timer is located on S-GW.Second timer starts when first timer is overtime, duration for keeping Idle state after first timer time-out to UE carries out timing, this section of duration progress timing of Idle state is still within for after first timer time-out, UE connection status does not change.When UE switchs to connected state from Idle state, second timer stops timing.Second timer
State can be divided into timeout mode and have not timed out state.Preset duration is provided with second timer, when the timing duration of second timer exceedes the preset duration on second timer, second timer is in timeout mode.
