Before other operation and foundation structure of each element that Fig. 1 is described in detail in detail, provide some upper and lowerThe general of when providing PSM to strengthen in network environment some problems that may run into is provided literary composition informationLook at. Such information provides cordially, and the object in order to instruct only, therefore should be with limitThe mode of making extensive use of the present disclosure makes an explanation.

In 3GPP the 12nd edition (Rel-12), introduce UE battery saving mode (PSM) feature.This feature allows to support the UE of PSM to enter to be similar to the state of power-off to keep it to arrive the note of network simultaneouslyVolume. Support the UE of PSM and can stop in PSM its Access Layer function deexcitationWhole idle pulley processes of state, but can continue to move any NAS timer, NAS meterTime device can adopt such as regular trace regions is upgraded (TAU) or routing region updating (RAU) meterTime device. This hint UE is not useable for Mobile Termination (MT) service, such as, data shift and letterOrder. But, exiting after PSM pattern, UE does not need again to adhere to or re-establish packet countConnect according to network (PDN), thereby and can realize the minimizing of radio and core network signaling.The UE that exits PSM state can restart mobile promotional activities at any time.

Generally speaking, subscriber equipment can in PSM model domain from second to hour any timeThe area of a room. The MME/SGSN serving for the UE of given support PSM knows the activity of authorizing this UETime, and during the PSM of UE state immediately refusal require that UE's paged (page) is completePortion's downlink communication. Such refusal can stride across multiple interfaces, such as, MME and visitor positionPut between SGs, MME between register (VLR) and SMS service center (SMSC)S11/S4 between SGd and MME/SGSN and SGW. Under the situation of S11 signaling, whenUE in the time of PSM state, GTPv2 Reason For Denial code #90 (UEUNREACHABLE(UE is unreachable)) be sent to SGW from MME. This reason-code is also used to work as MMEFor example, for example, because UE battery is pulled out suddenly (, not carrying out rightly separation process) and can notReach the conventional situation of UE when carrying out downlink transmission. Therefore, upstream node (for example, existsTo the SGW, the PGW etc. that relate in the downlink communication of UE) can not differentiate given UE and beWhat is unreachable.

In addition, access support the application service (AS) of UE of PSM not disclosed to UE based onThe state of network, and can attempt during in PSM state at UE sending Mobile Termination to UE(MT). Such Mobile Termination (MT) flow may be taken for the UE that supports PSM continuallyThe MME/SGSN refusal of business is delivered to UE. In UTE network for the (best that does one's bestEffort) packet loss of PDN is very common. But, support PSM UE inUnder the situation of PSM state, because UE may be " to be not useable for paging within the period extending(unavailableforpaging) ", so can observe following side effect:

A) SGW may have to optionally buffered data until exhaust its retry transmission policy;

B) during this period of time, between SGW and MME, (for example, there is unnecessary signalingS11 signaling), and between SGW and SGSN, there is unnecessary signaling (for example, S4 letterMake); And/or

C), for example, if sending entity (, AS) is not known the PSM state of UE, basis existsThe application layer protocol using between UE and AS communication, sending entity (for example, AS) can continueSend MT data, these MT data are by the signaling in aggravation network.

In addition, 3GPP network may need a kind of mechanism to trigger AS again to send that its originally intendsData. These frequent exchange can not increase value and can bring network congestion. For what developing3GPP the 13rd edition (Rel-13), expects by equipment manufacturers, service provider, network operationBusiness etc. solve the problem relevant with downlink accessibility.

According to each embodiment described herein, communication system 10 can be by providing following solutionOvercome above-mentioned shortcoming (and other), this solution can comprise should for (one or more)Subscribe to the skill of one or more triggerings by SCEF40 and MME30/SGSN34 with service 42Art, one or more triggerings can be used to (one or more) application service 42 provide aboutThe UE that when can reach given support PSM via MME30/SGSN34 is to receive Mobile Termination(MT) cognition of data.

In each embodiment, can provide communication system 10 to provide by the first optional modeSolution, wherein, for example, as UE (, the UE of will the be sent to given support of data PSM12), time, (one or more) application service 42 can be subscribed to being UE service via SCEF40" reachability event " of the given MME/SGSN MME30 of UE12 service (for example, for)Trigger. In the time that UE12 will can be used for receiving Mobile Termination (MT) data, reachability event touchesSend out can be used to signal to (one or more) application service 42 (for example, send " UE existsTo be able to reach in a short time " notice). In each embodiment, SCEF40 can inquire about HSS18 to be defined as the MME/SGSN of given UE service.

In each embodiment, can provide communication system 10 to provide by the second optional modeSolution, wherein, for example, in the time that data will be sent to given UE (, UE12), (oneIndividual or multiple) application service 42 can be via SCEF40 " subscription " to MME30/SGSN34" deactivate_PSM_at_UE_contact " trigger. For the second optional mode, term " is orderedRead " meaning be instruction (one or more) application service 42 passable, receive from UE at MME30Receive to TAU or SGSN34 from UE RAU and MME30/SGSN34 viaSCEF40 notice (one or more) application service 42UE is can for sending down link dataThat reach or by after can reaching, activate the function of MME30/SGSN34 with deexcitation UE'sPSM. For example, after the PSM of deexcitation UE12, MME30 can be logical via SCEF40Know that (one or more) application service 42 (one or more) application service can be initiated to UE'sDownlink (for example, MT) data. After any MT communication, (one or more) applicationService 42 can " cancel subscriptions " " deactivate_PSM_at_UE_contact ", and this will allowMME30 restarts the PSM of UE12.

For the first optional mode and the second optional mode, suppose MME30/SGSN34 andUE12 knows PSM active timer, and in the time that the PSM activity time expires, UE entersPSM state and the communication of therefore initiating for any network are inaccessible (for example, can notWith). As noted, in each embodiment, SCEF40 can inquire about HSS18 with reallyBe decided to be the MME/SGSN of given UE service.

In the operating period of the first optional mode, MME30/SGSN34 can monitor the week of UE12Phase property TAU/RAU timer and PSM active timer, this periodically TAU/RAU timer andPSM active timer can reach counter with the movement configuring for MME30/SGSN34(MRT) identical. In each embodiment, below any one in both occur after MME30/SGSN34 can send for reachability event and trigger to (one or more) application service 42Notice, to indicate in itself UE " will be able to reach in a short time " (for example,, in when regulationBetween can be used for receiving data in window): A) determine that periodically TAU/RAU timer is about to expireRear or B) receive after the service request (SR) or TAU/RAU that UE initiates. Real at eachExecute in example the whatsoever MRT moving based on MME30/SGSN34, MME30/SGSN34 can derive UE and expect when to carry out next periodicity TAU/RAU. Possesses thisKnowledge, MME30/SGSN34 can just expire it at the periodicity TAU/RAU of UE timerBefore can about the on the horizon of UE via (one or more) application service 42 of SCEF40 noticeReaching property.

In certain embodiments, MME30/SGSN34 can notify (one or more) application clothesBusiness 42 its down link data of the interior initiation of window at the appointed time. In each embodiment, ruleIt is to reach that the window of fixing time can be indicated the communication when UE initiates for (one or more) network. In each embodiment, stipulated time window can be defined as numerical value " X " second. At eachIn embodiment, time window can calculate and be provided for (one by MME30/SGSN34Individual or multiple) application service 42. In certain embodiments, MME30/SGSN34 can useThe periodicity TAU/RAU timer value of UE and PSM window computing time activity time. CauseThis, in each embodiment, if UE carry out conventional TAU/RAU (for example, due to radio/The change of core network character) if or UE because unexpected MO data are carried outSR, MME30/SGSN34 can notify (one or more) application service 42 it can beIn stipulated time window, initiate down link data.

In each embodiment, MME30/SGSN34 can also be forbidden this triggering. For example,, oneUnder a little situations, UE can no longer notice PSM ability, under these situations, may no longer need to lead toKnow/trigger. Therefore, for operating process by Mobile Termination (MT) data from (one orMultiple) application service is sent in each embodiment of UE12, and various combinations can become possibility,Include but not limited to:

A) (one or more) application service 42 sends down link data and SGW correspondinglyGenerate the DDN for MME/SGSN:

For example, if i) UE12 becomes and can reach (, exiting PSM state), MME30/SGSN34 can this UE of paging and this UE can send NAS service request.Then MME30/SGSN34 can set up carrying data path.

Ii) alternately, if periodically TAU/RAU timer expires, UE12 energyEnough initiate that TAU request and MME30/SGSN34 can choice for use receiveTAU/RAU sets up data path independently.

Iii) in another substitutes, if UE12 has initiated NAS service request, dataPath also can be established.

B), in the time that data path is established, (one or more) application service 42 can restartCommunicate by letter with UE.

When " reachability event " triggers at the MME/SGSN place that is given UE service subscribedTime, if UE carries out mobility TAU/RAU (example in the region of another MME ' s/SGSNAs, UE enter PSM and then another MME /PSM is exited in the region of SGSN),In each embodiment, source MME/SGSN for example, by the information about Event triggered (when, correspondingBetween trigger the AS identity that need to be delivered to) as mobile management (MM) contextual information unitA part for element (IE) sends to target MME/SGSN. By the first optional side of communication system 10The solution that formula provides can provide to the UE that enables PSM the MT data delivery of high likelihood.

For the second optional mode, as noted above, MME30 and UE12 both knowPSM active time, and (one or more) application service 42 can be ordered via SCEF40Read for MME30/SGSN34 " deactivate_PSM_at_UE_contact " and trigger. BehaviourDo in process, in the time that (one or more) application service 42 need to send data to UE12,(one or more) application service 42 can pass " deactivate_PSM_at_UE_contact "Deliver to MME30. In the time that its TAU is sent to MME30 by UE12, at least from (oneIndividual or multiple) during the transfer of the MT data of application service 42 corresponding active timer not byMME30 distributes to UE. In the time that the activity time is not assigned to UE12, it can be converted toIDLE (free time) pattern (for example, EPS Connection Management-free time (ECM-IDLE) pattern) stillCan retain its access layer function, therefore, make it can be used for paging (for example, MT signaling) alsoAnd therefore can be used for any MT data. After the PSM deexcitation to UE12, MME30 energyEnough send notice with instruction UE12 couple via SCEF40 to (one or more) application service 42In receive from (one or more) application service 42 Mobile Termination (MT) data be can reach orTo be able to reach in a short time

In each embodiment, once (one or more) application service 42 completes it to UE12Data communication, and if (one or more) application service no longer needs UE maintenance activity,(one or more) application service can be removed " deactivate_PSM_at_UE_contact "(triggering of for example, subscribing to MME30 via SCEF40 is with in follow-up TAU in the subscription triggeringEnable the PSM of UE12). This allows MME30 when with next routine of UE or periodic communicationRestart the PSM of UE12.
