It is traffic model transmission flow schematic diagram provided in an embodiment of the present invention, which may include walking as follows referring to Fig. 3
It is rapid:
Step 301:SCEF entity receives the traffic model of terminal, and the traffic model of the terminal is sent to the first MME,
And the traffic model of the terminal is cached, the first MME is the service MME of the terminal；
Step 302: whether the service MME that the SCEF entity monitors the terminal changes, if monitoring the end
The service MME at end changes, then the traffic model of the terminal of caching is sent to the 2nd MME, the 2nd MME is institute
State the new service MME of terminal.
In the step 302 of above-mentioned process, after SCEF entity monitors that the service MME of the terminal changes, it can inquire
HSS determines the new MME of the terminal, i.e., described 2nd MME according to query result, thus by the communication of the terminal of caching
Model is sent to the 2nd MME.
In above-mentioned process, SCEF entity monitor the terminal the whether changed operation of service MME can always into
Row, in this way, once monitor that the service MME of the terminal changes in step 302, it can be by the terminal of caching
Traffic model is sent to the 2nd MME.
The particular content that the traffic model of the terminal is included can be found in the regulation of communication protocol.For example, terminal is logical
Believe that model may include following parameter:
The relevant template of time flow, such as periodic communication time interval, it is the keepalive period of data session, average
Or maximum volume of transmitted data etc.；
Whether position or the relevant target of mobility, such as terminal are static, the prediction locus etc. of terminal.
In above-mentioned process, SCEF entity can configure the situation of change that HSS monitors the service MME of the terminal.
Specifically, HSS monitors that monitoring report is sent when the service MME of the terminal changes gives SCEF entity,
After SCEF entity receives the monitoring report of HSS transmission, determine that the service MME of the terminal becomes according to the monitoring report
Change.
Further, after SCEF entity receives the traffic model of the terminal, receive monitoring report that HSS is sent it
Before, the whether changed monitoring event of service MME for monitoring the terminal is also produced, and the monitoring event is sent out
The HSS is given, to configure whether the service MME of HSS terminal according to the monitoring event monitoring changes.
In above-mentioned process, the service MME that SCEF entity can also be configured terminal monitors the variation feelings of the service MME of the terminal
Condition.
Specifically, the first MME monitors that monitoring report is sent when the service MME of the terminal changes gives SCEF reality

The process of the traffic model of SCEF entity transmission terminal is described in detail.
Embodiment one
Referring to fig. 4, after SCEF entity receives the traffic model of UE, on the one hand the traffic model is transmitted, it is another
Aspect generates the monitoring event of the UE and is allocated to HSS, and whether the service MME which is used to monitor UE changes.
Specifically, which may include following steps:
The traffic model of step 401:SCEF entity reception UE.Specifically, SCEF entity can be sent logical by SCS/AS
Know the traffic model of message sink UE.
Step 402:SCEF entity is that the UE generates monitoring event (English are as follows: monitoring event), the monitoring thing
Part is used to monitor the situation of change of the service MME (English are as follows: serving MME) of the UE.
Optionally, it when SCEF entity selection monitors event to HSS allocation, may be selected only to report that a serving MME becomes
Change or persistently report MME changes.
Step 403:SCEF entity request to inquire to HSS by Context query the UE context (English are as follows:
Profile), and when to the context of HSS inquiry UE, the monitoring thing generated for the UE is carried in the Context query request
Part.
Step 404:HSS requests to inquire the context of the UE according to the Context query, and is rung by Context query
The context that the UE should be returned to SCEF entity, the mark of the service MME of internal indicator and the UE including the UE, and really
Recognize and receives the monitoring event.
Wherein, the internal indicator of UE can include but is not limited to M-TMSI (TMSI be Temporary Mobile
The English abbreviation of Subscriber Identity, i.e. Temporary Mobile Subscriber Identity), S-TMSI or GUTI (Globally Uniqe
Temporary Identity, the unique interim subscriber identity in the whole world) etc., the mark of MME can include but is not limited to GUMME
(Globally Unique MME Identity, the unique MME mark in the whole world).
Step 405:HSS installs the monitoring event, and after the monitoring event is installed according to the monitoring event to the UE's
The situation of change of service MME is monitored.
After step 406:SCEF entity receives the Context query response of HSS return, is returned to SCS/AS and be directed to step 401
Push-notification-answer.
Step 407:SCEF entity sends the traffic model of the UE to the service MME of UE.
Step 408:SCEF entity caches the traffic model of the UE.
Step 409: the service MME of the UE generates optimization of network parameters according to the traffic model of the UE, for example is the UE's
It services eNB and generates core net auxiliary parameter (English are as follows: CN assisted eNB parameters).
Further, after step 409, the service MME of the UE, will be for the service of the UE in S1 loading establishing process
The core net auxiliary parameter that eNB is generated is supplied to the eNB, the core net auxiliary parameter which is provided according to the MME
Some network optimization measures are taken, such as reduce conversion of the UE between Idle state and connected state, reduce the movement for influencing the MME
Property managing signaling.
Further, above-mentioned process shown in Fig. 4 can comprise the further steps of:
Step 410:SCEF entity the UE of caching traffic model failure after, such as the UE traffic model it is effective
Phase is expired, removes the traffic model of failure.
It further,, can also be according to being currently received after SCEF entity receives the traffic model of UE in step 401
The traffic model of UE, the traffic model in query caching with the presence or absence of the same type for belonging to the UE are then transferred to step if it does not exist
Rapid 402 continue to execute process shown in Fig. 4.
If it is present show the traffic model of the same type of the received mistake UE before this, what this was received
The traffic model of the UE is updated traffic model, in this case, the communication of the SCEF entity UE being currently received
Model updates the traffic model for belonging to the same type of the UE in caching, and the updated traffic model of the UE is sent to
The service MME of the UE is reported without obtaining the context of the UE again without monitoring is generated again for this kind of traffic model of the UE
It accuses.Specifically, Fig. 5 schematically illustrates above-mentioned treatment process.
As shown in fig. 5, it is assumed that after certain traffic model of UE is sent to SCEF entity for the first time by SCS/AS, according to
Fig. 4 or process shown in fig. 5 are sent to the service MME of the UE, and hereafter, SCS/AS has carried out more this kind of traffic model of the UE
Newly, and by updated traffic model it is sent to SCEF entity, hereafter, following process can be performed in SCEF entity:
The traffic model of step 501:SCEF entity reception UE.Specifically, SCEF entity can be sent logical by SCS/AS
Know the traffic model of message sink UE.
The traffic model of the UE of step 502:SCEF entity lookup caching, judgement, which has existed, belongs to the mutually similar of same UE
The traffic model of type then updates the communication mould of the same type of the UE in caching according to the traffic model that step 501 receives
Type.
Step 503:SCEF entity returns to the push-notification-answer for being directed to step 501 to SCS/AS.
Step 504:SCEF entity sends traffic model to the service MME of the UE, which is to receive in step 501
The traffic model arrived.
Step 505: the service MME of the UE generates optimization of network parameters according to the traffic model of the UE.
In the step 401 of process shown in Fig. 4, the traffic model of UE or one group of UE can be passed through notification message by SCS/AS
It is sent to SCEF entity.
If only including the traffic model of a UE in notification message, execute according to the above process.
If in notification message including the traffic model of one group of UE, step 402 can be executed for this group of UE to step
406, step 407 is executed for each UE in this group of UE.Specifically, in step 402, raw for each UE in this group of UE
The context of each UE in this group of UE is inquired in step 403 to step 404 at monitoring event；In step 407, for
Each UE in this group of UE sends traffic model to the service MME of UE respectively.
Process shown in Fig. 4 illustrates only a kind of typical signaling time-sequence process, but protection scope of the present invention and unlimited
In this.
For example, the step of traffic model of SCEF entity caching UE, can also execute, such as at other times in step
To any time point of a period of time before step 410 after 401.Preferably, the communication of UE can be received in SCEF entity
The traffic model is cached immediately after model, alternatively, as shown in Figure 4, the traffic model of UE is successfully being transferred to the UE's
After servicing MME, the traffic model of the UE is cached.
For another example the monitoring event of generation is sent to HSS by Context query request by SCEF entity, original can be multiplexed
Some message is to reduce signaling overheads.Optionally, SCEF entity is that the step of UE generates monitoring event can also be at other times
It executes, for example, generating monitoring event after the context for inquiring the UE to HSS for the UE, and will by a notification message
The monitoring event is sent to HSS.
Referring to Fig. 6, the monitoring event report that SCEF entity is reported according to HSS carries out the re-transmission of traffic model.Specifically, should
Process may include following steps:
Step 601:HSS receives the location updating that the new service MME (English are as follows: new serving MME) of UE is sent
(English are as follows: update location) message, at this point, HSS monitors that the service MME of UE changes.
The service MME that the location updating of UE may cause the UE changes, and the new serving MME of the UE can be to
HSS obtains the subscription data of the UE, at this point, the monitoring event of the UE configured on HSS is triggered, HSS monitors the UE's
Service MME changes.
Step 602:HSS sends monitoring report to SCEF entity, is become the service MME of the UE by the monitoring report
The case where change, notifies to give SCEF entity.The mark of the new serving MME of the UE can be carried in the monitoring report.
After step 603:SCEF entity receives monitoring report, the traffic model of the UE of caching is searched.
The traffic model of the UE inquired is sent to the new serving MME of the UE by step 604:SCEF entity.
Embodiment two
Referring to Fig. 7, after SCEF entity receives the traffic model of UE, on the one hand the traffic model is transmitted, it is another
Aspect generates the monitoring event of the UE and the service MME by the monitoring event configuration to the UE, and the monitoring event is for monitoring UE
Service MME whether change.It is allocated to HSS by event configuration is monitored to the service MME of UE, it can be to avoid right
The influence of HSS.Specifically, which may include following steps:
The traffic model of step 701:SCEF entity reception UE.Specifically, SCEF entity can be sent logical by SCS/AS
Know the traffic model of message sink UE.Wherein, SCS/AS indicates SCS or AS, or the SCS and AS that integrate.
Step 702:SCEF entity request to inquire to HSS by Context query the UE context (English are as follows:
profile)
Step 703:HSS requests to inquire the context of the UE according to the Context query, and is rung by Context query
The context that the UE should be returned to SCEF entity, the mark of the service MME of internal indicator and the UE including the UE.
Wherein, the internal indicator of UE can include but is not limited to M-TMSI, S-TMSI or GUTI etc., and the mark of MME can be with
Including but not limited to GUMME.
After step 704:SCEF entity receives the Context query response of HSS return, is returned to SCS/AS and be directed to step 701
Push-notification-answer.
Step 705:SCEF entity is that the UE generates monitoring event (English are as follows: monitoring event), the monitoring thing
Part is used to monitor the situation of change of the service MME (English are as follows: serving MME) of the UE.Further, which further includes prison
After surveying the serving MME variation that the UE occurs, the new service MME (English are as follows: new serving MME) of UE is reported.
It optionally, is only by monitoring event configuration when SCEF entity selection configures monitoring event to the serving MME of UE
Report a serving MME variation.
Step 706:SCEF entity sends traffic model and monitoring event to the serving MME of UE.Wherein, the communication of UE
Model and monitoring event can be sent by a piece of news, and the traffic model of UE can also be sent by a piece of news, then pass through one
The monitoring event of message transmission UE.
Step 707: the service MME of the UE generates optimization of network parameters according to the traffic model of the UE, for example is the UE's
It services eNB and generates core net auxiliary parameter (English are as follows: CN assisted eNB parameters).
Step 708: the service MME of the UE installs the monitoring event, and according to the monitoring thing after installing the monitoring event
Part is monitored the situation of change of the service MME of the UE.
Step 709:SCEF entity caches the traffic model of the UE.
Further, after step 707, the service MME of the UE, will be for the service of the UE in S1 loading establishing process
The core net auxiliary parameter that eNB is generated is supplied to the eNB, the core net auxiliary parameter which is provided according to the MME
Some network optimization measures are taken, such as reduce conversion of the UE between Idle state and connected state, reduce the movement for influencing the MME
Property managing signaling.
Further, above-mentioned process shown in Fig. 7 can comprise the further steps of:
Step 710:SCEF entity the UE of caching traffic model failure after, such as the UE traffic model it is effective
Phase is expired, removes the traffic model of failure.
It further,, can also be according to being currently received after SCEF entity receives the traffic model of UE in step 701
The traffic model of UE, the traffic model in query caching with the presence or absence of the same type for belonging to the UE are then transferred to step if it does not exist
Rapid 702 continue to execute process shown in Fig. 7.
If it is present show the traffic model of the same type of the received mistake UE before this, what this was received
The traffic model of the UE is updated traffic model, in this case, the communication of the SCEF entity UE being currently received
Model updates the traffic model for belonging to the same type of the UE in caching, and the updated traffic model of the UE is sent to
The service MME of the UE is reported without obtaining the context of the UE again without monitoring is generated again for this kind of traffic model of the UE
It accuses.Specifically, Fig. 5 schematically illustrates above-mentioned treatment process.
In the step 701 of process shown in Fig. 7, the traffic model of UE or one group of UE can be passed through notification message by SCS/AS
It is sent to SCEF entity.
If only including the traffic model of a UE in notification message, execute according to the above process.
If in notification message including the traffic model of one group of UE, step 702 can be executed for this group of UE to step
705, step 706 is executed for each UE in this group of UE.Specifically, it in step 702 to step 705, inquires in this group of UE
Each UE context, and generate monitoring event for each UE in this group of UE；In step 706, in this group of UE
Each UE, respectively to the service MME of UE send traffic model and monitoring event.
Process shown in Fig. 7 illustrates only a kind of typical signaling time-sequence process, but protection scope of the present invention and unlimited
In this.
For example, the step of traffic model of SCEF entity caching UE, can also execute, such as at other times in step
To any time point of a period of time before step 710 after 701.Preferably, the communication of UE can be received in SCEF entity
The traffic model is cached immediately after model, alternatively, as shown in Figure 7, the traffic model of UE is successfully being transferred to the UE's
After servicing MME, the traffic model of the UE is cached.
Referring to Fig. 8, SCEF entity carries out the re-transmission of traffic model according to the monitoring event report that the service MME of UE is reported.
Specifically, which may include following steps:
Source service MME (i.e. old MME) of step 801:UE judges the service of the UE according to the interface message between MME
Whether MME changes.
Step 802: if the old MME of the UE judges that the service MME of the UE changes, by the service MME of the UE
The case where changing is sent to SCEF entity by monitoring report.Further, the old MME of the UE is also by the new of the UE
The information of service MME (new serving MME) SCEF entity is sent to by monitoring report such as the mark of MME.
After step 803a receives monitoring report to step 803b:SCEF entity, if not comprising the UE in monitoring report
The information of new serving MME, then SCEF entity inquires the information of the new serving MME of the UE to HSS.The step is
Optional step.
The traffic model of the UE of step 804:SCEF entity lookup caching.
The traffic model of the UE inquired is sent to the new serving MME of the UE by step 805:SCEF entity.
By can be seen that above to the description of the embodiment of the present invention, on the one hand, SCEF entity receives the communication of terminal
After model, which is sent to the service MME of the terminal, without being sent to HSS and being sent to the service of terminal by HSS
