Description

A kind of method, apparatus and M2M management platforms sending message to UE
Technical field
The present embodiments relate to field of communication technology, more particularly to it is a kind of to UE send message method, apparatus and M2M management platforms.
Background technology
In Internet of Things, user terminal (User Equipment, UE) is in machine and machine (Machine to Machine, M2M) management platform registration, the default reachable time list of M2M management platforms preservation terminal, this is default up to the time List includes the default information up to the period of UE.Application server to UE send downlink data request message when, first will under Row data request information is sent to M2M management platforms, and M2M management platforms send the downlink up to the period in the default of UE to UE Data request information.
UE enters idle (Idle) when no uplink business data needs to send from that can connect (Connected) state State, and enter battery saving mode (Power Save Mode, PSM) after maintaining one section of duration of Idle states.Wherein, UE Idle states are also known as reachable state.As it can be seen that the period that UE is practically in reachable state is dynamic, whether have depending on UE Uplink service demand.
But M2M management platforms preserve it is default immobilize up to the period, with UE be practically in reachable state when Between section have differences, lead to that UE preserves in M2M management platforms is default up to PSM is likely to be in the period, if M2M is managed Platform at this moment to UE send downlink data request message, UE will move out PSM receive message so that UE in PSM when Between shorten, be unfavorable for save UE electricity, cause the stand-by time of UE to shorten.
Invention content
The embodiment of the present invention provide it is a kind of to UE send message method, apparatus and M2M management platforms, for solve because PSM timer in network server in M2M management platforms it is default up to time list it is asynchronous cause UE it is standby when Between the problem of shortening.
First aspect of the embodiment of the present invention provides a kind of method sending message to user terminal UE.First, M2M management is flat Platform receives the downlink data request message that application server AS is sent, and the downlink data request message includes the mark of target UE Know；The target UE's that the M2M management platforms are locally preserved according to the identifier lookup of the target UE is default up to the time List, the default default information up to the period that the target UE is preserved up to time list are described default reachable Period refers to the Idle states duration of UE at the time of entering Idle states according to UE and in PSM timer, location updating week The UE that phase is expected is in the period of reachable state；The M2M management platforms determine described default up in time list Source parameter is network N etwork, and the source parameter is that Network shows described default up to described pre- in time list If up to rising for the idle Idle status timers in the initial time and network server of period being the target UE settings Beginning, the moment is identical, i.e., default reachable time list is synchronous with the PSM timer in network server；The M2M management platforms are sentenced Whether disconnected current time T1 is located at described default up within the period；If so, the M2M management platforms are to the target UE Send the downlink data request message.
Source parameter due to presetting reachable time list in M2M management platforms is Network, i.e., default to be arranged up to the time Table is synchronous with the PSM timer in network server.So when current time T1 was located within the default reachable period, when Preceding moment T1 is also in network server in the defined Idle status time periods of PSM timer, rather than in network server In the defined PSM periods of middle PSM timer.M2M management platforms send the downlink data request message in T1 to UE, will not So that the PSM periods of UE is reduced, ensures that UE has longer stand-by time.
In some realization methods of first aspect, the downlink data request message further include request exceed the time limit timestamp with And operation executes the time；The M2M management platforms judge T1 whether be located at it is described it is default up within the period when, according to The default initial time T2 that next default reachable period after T1 is determined up to time list；Judge that the request is super Phase timestamp and the operation execute whether the time is later than T2；If so, under the M2M management platforms are after the T1 One default up within the period and in the target UE described in timestamp and the forward direction of the operation execution time that exceeds the time limit Send the downlink data request message.Since M2M management platforms are not in current time T1 in the default reachable period When, it can be next default up within the period and in the forward direction target UE hairs of timestamp and operation execution time that exceed the time limit Send downlink data request message so that UE can receive downlink data request message in time, obtain AS transmissions as early as possible convenient for UE Downlink application data.
In some realization methods of first aspect, the M2M management platforms are judging that the request exceeds the time limit timestamp And the operation, when executing the time and whether being later than T2, returning to the downlink data request message to the AS cannot be sent to The errored response of the target UE informs that AS downlink datas request message cannot be successfully transmitted.
In some realization methods of first aspect, the M2M management platforms are judging that the request exceeds the time limit timestamp When earlier than T2, returning to the downlink data request message to the AS cannot exceed the time limit to be sent to institute before timestamp in the request The errored response for stating target UE, the request that the setting of downlink data request message is corrected as convenient for AS are exceeded the time limit timestamp.
In some realization methods of first aspect, the M2M management platforms are judging that the request exceeds the time limit timestamp When being later than T2 and the operation and executing the time earlier than T2, returning to the downlink data request message to the AS cannot be in the behaviour The mistake of the target UE is sent to before making the execution time, the operation that the setting of downlink data request message is corrected as convenient for AS is held The row time.
In some realization methods of first aspect, the M2M management platforms are judging that the request exceeds the time limit timestamp And the operation execute in the time it is any earlier than T2 when, the M2M management platforms to the AS send it is described it is default up to when Between information up to the period is preset in list, the default information up to the period, which is used to indicate, asks the downlink data Exceed the time limit timestamp and the operation of the request in message is asked to execute after time modification is the reachable time not yet to arrive, So that M2M management platforms can send out the downlink data request message for having modified time limit parameter up in the period default Give UE..
In some realization methods of first aspect, the M2M management platforms subscribe to the target UE to network server Idle states receive the registration request of the target UE, the registration request includes the default up to the period of the target UE Information；Described default up to time list locally being created for the target UE, the default reachable time list includes institute It states described default up to the period in registration request；Receive the Idle state reports for the target UE that network server returns It accuses, the Idle state reports include the mark of the target UE and at the time of the target UE enters Idle states, network When server detects that UE switches to Idle states from Connected states, the Idle state reports are sent to M2M management platforms It accuses；As the default initial time up to the period at the time of target UE is entered Idle states；And it will be described pre- If the source parameter up to time list is set as Network.In this realization method, M2M management platforms will be default reachable After time list is synchronous with the PSM timer being arranged in network server, the default source parameter up to time list is set It is set to Network, it is default synchronous with the PSM timer being arranged in network server up to time list to show.M2M is managed Platform determines when according to default up to time list after receiving AS requests and being sent to the downlink data request message of UE The downlink data request message is sent to UE, ensures that the PSM durations of UE are not reduced.
In some realization methods of first aspect, the M2M management platforms send source parameter to the target UE and set It is set to the described default up to the information preset in time list up to the period of Network.Since M2M management platforms are sent out to UE The default information up to the period sent is synchronous with the PSM timer in network server, thus UE locally preserve can Synchronous with the PSM timer in network server up to the period, UE keeps Idle states according to the reachable period locally preserved Time in network server UE as defined in PSM timer be in the period of Idle states, rather than in network service UE as defined in PSM timer was within the period of PSM in device, avoided UE in the PSM periods as defined in PSM timer It is kept for the PSM periods of UE caused by Idle states reduce, ensures that UE has longer stand-by time.
In some realization methods of first aspect, the M2M management platforms also receive the second downlink that the AS is sent Data request information, the second downstream data request message include the mark of the second target UE；According to the second target UE Identifier lookup locally preserve it is the second of the second target UE default up to time list；Determine that described second is default reachable Source parameter in time list is equipment Device；It is default up to time row to judge whether current time T3 is located at described second It is default up within the period in table；If so, sending the second downstream data request message to the second target UE. In this realization method, when being set as Device due to the source parameter of the second default reachable time list in M2M management platforms, It is consistent with the default reachable period that the second target UE is locally preserved that the reachable period is preset in M2M management platforms, so in M2M At the time of presetting up in the period in management platform, UE is default up to period holding Idle states according to what is locally preserved. Default reachable period of the M2M management platforms in the second default reachable time list sends downlink data request message to UE, UE is in Idle states, ensures that UE being capable of downlink data request message timely, that the transmission of M2M management platforms is correctly received.
In some realization methods of first aspect, the M2M management platforms are judging that T3 is not at described second When within the default default reachable period up to time list, the last message for receiving the second target UE is determined Moment T4, since UE to M2M management platforms in Connected states after sending upstream message, if without upstream data Transmission demand can then be switched to Idle states by Connected states, and therefore, M2M management platform the last times receive the second mesh T4 differs very little at the time of switch to Idle states by Connected states with the second target UE at the time of marking the message of UE, and two Person's deviation can be ignored, and the T4 is considered as the second target UE in the embodiment of the present invention switches to Idle by Connected states At the time of state；Judge whether the difference of T3 and T4 is more than the Idle state durations of the second target UE；If being not more than, institute It states M2M management platforms and sends the second downstream data request message to the second target UE.In present embodiment, current When the difference of the moment T3 and T4 is not more than the Idle state durations of the second target UE, when M2M management platforms can determine current It carves time interval at the time of T3 distances the second target UE is switched to Idle states by Connected states and not yet exceeds the second mesh The Idle state durations for marking UE, show current time T3 still as defined in the PSM timer of network server when Idle states Between within section.M2M management platforms send the second downstream data request message at the T3 moment to the second target UE, can not only make It obtains the second target UE and receives the second downstream data request message in time.Moreover, because M2M management platforms are sent out to the second target UE At the time of giving the second downstream data request message T3 Idle status time periods as defined in the PSM timer of network server it It is interior, rather than within the PSM periods as defined in the PSM timer of network server, therefore, in M2M management platforms to second Target UE, which sends the second downstream data request message, will not cause the PSM periods of the second target UE to reduce, and ensure the second mesh Marking UE has longer stand-by time.
In some realization methods of first aspect, the M2M management platforms are more than institute in the difference for judging T3 and T4 When stating the Idle state durations of the second target UE, the mistake that presently described second target UE is in inaccessible state is returned to the AS It accidentally responds, informs that AS second downstream data request messages fail and be sent to the second target UE.
Second aspect of the embodiment of the present invention provides a kind of synchronous method.First, M2M management platforms are subscribed to network server The Idle states of target UE；Then, the M2M management platforms receive the registration request of the target UE, the registration request packet Include the default information up to the period of the target UE；Then, the M2M management platforms are being locally that the target UE is created Default reachable time list, the default reachable time list include described default up to the period in the registration request； Then, the M2M management platforms receive the Idle state reports for the target UE that network server returns, the Idle states Report includes the mark and target UE at the time of enter Idle states of the target UE；Then, the M2M management platforms As the default initial time up to the period at the time of target UE is entered Idle states；And it can by described preset The source parameter up to time list is set as Network；Then, the M2M management platforms send institute to the target UE It states default up to the information preset in time list up to the period.In this realization method, when M2M management platforms will be default reachable Between list it is synchronous with the PSM timer being arranged in network server after, will the default source parameter setting up to time list It is default synchronous with the PSM timer being arranged in network server up to time list to show for Network.M2M is managed Platform after receiving AS requests and being sent to the downlink data request message of UE, according to it is default up to time list determine when by The downlink data request message is sent to UE, ensures that the PSM durations of UE are not reduced.
In some of first aspect or second aspect realization methods, in the M2M management platforms according to the target UE The target UE that locally preserves of identifier lookup it is default up to before time list, further include：
The M2M management platforms receive the registration request of the target UE, and the registration request includes the target UE The default information up to the period；
The M2M management platforms are that the target UE creates the default reachable time list in local, and described preset can Include described default up to the period in the registration request up to time list.
In some of first aspect or second aspect realization methods, the Idle state reports further include the target UE Idle states duration and the location updating period；Alternatively, the Idle status timers in the network server are by institute The setting of M2M management platforms is stated, the M2M management platforms preserve the Idle states duration and the location updating period； As when the starting of the default reachable period at the time of target UE is entered Idle states by the M2M management platforms After quarter, further include：When at the time of the target UE being entered Idle states by the M2M management platforms plus the Idle states At the time of long, as the default default finish time up to the period up in time list；And by the position Update cycle is as described default up to the adjacent default time interval up between the period in time list.Present embodiment Default duration and Idle state durations up to the period can be caused inconsistent or adjacent to avoid due to the mistake being likely to occur Default interval and location updating period up between the period is inconsistent, it is ensured that default up to time list and network server The PSM timer of middle setting are synchronized.

Specific implementation mode
The technical solution that embodiment provides to facilitate the understanding of the present invention, first introduces the relevant prior art below.
Fig. 1 is the idle Idle states of UE and the schematic diagram of battery saving mode PSM.UE is in can connect Connected When state, if not having transmitting uplink data demand, Idle states can be entered, Idle states are maintained preset duration by UE.Such as Fruit UE has transmitting uplink data demand under Idle states, then switches to Connected states and carry out data transmission.If at this Still transmitting uplink data demand, UE is not had then to switch to battery saving mode PSM in preset duration.UE closes radio frequency when being in PSM Module switches to Connected states to realize power saving after maintaining another preset durations of PSM, has checked whether data biography Defeated demand.Wherein, UE is in periods of Idle states and is known as reachable period of UE.
Fig. 2 is that PSM timers are arranged in network server in UE and is that UE is preset in the setting of M2M management platforms up to the time The flow diagram of list, the flow include the following steps：
Step 101, UE negotiates with network server, determines the parameter of the battery saving mode timer PSM timer of UE.
Above-mentioned negotiations process can pass through attachment (attach) flow of UE, tracing section updating (Tracking Area Update, TAU) realizations such as flow or Routing Area Update (Route Area Update, RAU) flow.The ginseng of the PSM timer Number includes the Idle states duration of UE and the location updating period of UE, which can be TAU periods or RAU weeks Phase.Referring to Fig.1, the Idle state durations of UE refer to UE from Idle states are entered to the duration switched to PSM, and position is more The Idle state durations that the new period subtracts the UE are the duration that UE maintains PSM.For the ease of distinguishing, in the embodiment of the present invention, The Idle state durations of the UE are known as the first preset duration, which is known as the second preset duration, which maintains The duration of PSM is known as third preset duration.
Step 102, network server returns to the PSM timer parameters of setting to UE.
The PSM timer parameters include the Idle states duration of above-mentioned UE and the location updating period of UE.
Step 103, the PSM timer for the PSM timer parameter settings local that UE is returned according to network server.
The PSM timer parameters of the locals UE are consistent with the PSM timer parameters that network server returns.
Step 104, UE determines that UE's is default up to the period according to local PSM timer.
So-called default UE's at the time of refer to entering Idle states according to UE up to the period and in PSM timer The UE that Idle states duration, location updating period are expected is in the period of reachable state.
For example, the timestamp (timestamp) when UE enters Idle states is 2:It is a length of when 00, UE Idle states 30min, location updating period are 4 hours, and the default of UE is up to the period：2:00-2:30,6:00-6:30,10:00- 10:30,14:00-14:30,18:00-18:30,22:00-22:30.
Step 105, UE sends upstream message to M2M management platforms, which includes the default up to the period of UE Information.
Step 106, M2M management platforms are that UE creates preset time period list, which includes UE It is default up to the period.
Referring to table 1, which can be indicated by timetable (schedule).
Table 1
Wherein, the numerical value 0 in " all numbers " refers to Sunday.
Timestamp in Idle states above is 2:In 00 example, presets and use 1 format table of table up to time list When showing, the numerical value on " score " column is set as " 0-30 ", and " when number " column is set as " 2,6,10,14,18,22 ".
Step 107, PSM timer are arranged for UE in network server according to preset time period list in M2M management platforms.
M2M management platforms can determine the ginsengs such as Idle states duration and location updating period according to preset time period list Number, and PSM timer are arranged for UE in network server according to determining parameter.
Step 108, UE synchronizes the parameter of PSM timer from network server.
UE can synchronize the parameter of PSM timer by TAU flows from network server.
It is managed for the PSM timer and M2M of UE settings although can temporarily be realized in network server by above-mentioned flow It is synchronized for the default reachable time list that UE is preserved in platform, i.e., default default reachable period and root up in time list It is overlapped up to the period according to determined by PSM timer.But above-mentioned synchronize is unsustainable, with the operation of UE, network Default reachable time list in PSM timer and M2M management platforms in server becomes asynchronous.
This is because the default preset time period up in time list in M2M management platforms is absolute time section, tool There are determining initial time and finish time.And the reachable period of UE as defined in the PSM timer in network server is Dynamically, when initial time switches to because not having transmitting uplink data demand depending on UE under Connected states Idle states.Therefore, it as UE is run, will necessarily be managed with M2M at the time of UE switches to Idle states by Connected states Deviation occurs for the fixed initial time of the preset time period in platform, and the PSM timer and M2M in network server is caused to manage Default reachable time list in platform becomes asynchronous.
PSM timer in network server are default asynchronous up to time list in M2M management platforms and will lead Cause the PSM periods of UE less.This is because M2M management platforms by it is default up to time list it is default up to the period to UE sends downlink data, and UE also can switch to Idle states to receive M2M management in the default reachable period locally preserved The downlink data that platform is sent.But due to default reachable in the PSM timer and M2M management platforms in network server Time list is asynchronous, and at the time of in the default reachable period in default reachable time list, such as timestamp is 2:00 Example at the time of 6:20, the PSM moment should be according to the definition of PSM timer in network server.Therefore, UE should locate In PSM time-switching to Idle states, cause the time that UE is practically in PSM to reduce, the stand-by time of UE shortens.
It is arranged with the default reachable time in M2M management platforms to solve the above-mentioned PSM timer because in network server Table asynchronous the problem of causing the stand-by time of UE to shorten, M2M management platforms in the embodiment of the present invention it is default up to the time Added with the source parameter up to time list is shown in list, when in source, parameter is network (Network), M2M management Platform determines that default reachable time list is synchronous with the PSM timer in network server, and in default reachable time list It is default to send downlink data request message to UE up in the period.Due to default up in time list and network server PSM timer are synchronized, so at the time of M2M management platforms send downlink data request message to UE in network server In the Idle status time periods that PSM timer are defined, avoids UE and switched in the PSM periods as defined in PSM timer Idle states ensure that the PSM periods of UE are not reduced so that UE has longer stand-by time.
The embodiment of the present invention is discussed in detail below in conjunction with the accompanying drawings.

UE10 refers to the equipment for providing a user voice and/or data connectivity, such as may include having to be wirelessly connected The portable equipment of function or the processing equipment for being connected to radio modem.UE10 can be through wireless access network (Radio Access Network, RAN) it is communicated with core net, voice and/or data are exchanged with RAN.UE10 may include mobile electricity Words (or being " honeycomb " phone), removable computer, tablet computer, personal digital assistant (Personal Digital Assistant, PDA), media player, smart television etc..In the embodiment of the present invention, UE10 can be with the network in core net Server 3 communicates, for example, UE10 negotiates the parameter of PSM timer with network server 30, PSM is received from network server The parameter of timer.UE10 can be configured with application service, be communicated with M2M management platforms 20 by core net, for example, UE10 Registration request is sent to M2M management platforms 20 by core net, the default up to the time of UE10 can be carried in the registration request The information or UE10 of section carry the default reachable of UE10 by core net after sending registration request to M2M management platforms 20 The message of the information of period；In another example UE10 receives the lower line number sent by AS40 by core net from M2M management platforms 20 According to request message, the downlink data request message is responded.In some embodiments, UE10 is additionally operable to receive M2M by core net The source parameter that management platform 20 is sent is arranged to the default default reachable period up in time list of Network Information, the default reachable period locally preserved according to the default information update up to the period of reception, with default at this Idle states are switched to up to the period, receive the downlink data request message that M2M management platforms 20 are sent.
Application server AS 40 is used to provide application service to UE10, for example, AS40 sends downlink data request to UE10 Message, in the embodiment of the present invention, downlink data request message is sent to M2M management platforms 20 by AS40, asks M2M management platforms 20 forward the downlink data request message to UE10.In another example AS40 can be also used for receiving the pre- of 20 transmission of M2M management platforms If up to the information preset in time list up to the period, by the request in downlink data request message exceed the time limit timestamp and Operation executes after time modification is the reachable time not yet to arrive.
M2M management platforms 20 are used to carry out equipment management (Device Management, DM) to UE10.Specifically, M2M PSM timer can be arranged for UE10 in network server 30 in management platform 20；M2M management platforms 20 are locally preserving UE10 It is default up to time list, receive the downlink data request message that AS40 is sent to UE, and according to preservation it is default reachable when Between list determine when to send the downlink data request message to UE10.For example, the source in default reachable time list is joined When number is Network, it is default up within the period that M2M management platforms 20 judge whether current time T1 is located at；If so, M2M management platforms send downlink data request message to target UE.In another example if when current time T1 is not at default reachable Between within section, M2M management platforms 20 according to it is described it is default determine up to time list it is next default up to the period after T1 Initial time T2；M2M management platforms 20 judge request exceed the time limit timestamp and operation execute the time whether be later than T2；If Be that then M2M management platforms cache the downlink data request message, and after tl it is next it is default up within the period and Exceed the time limit timestamp and the forward direction target UE transmission downlink data request messages of operation execution time.For another example if request is exceeded the time limit Timestamp and operation execute any earlier than T2 in the time, then M2M management platforms return to downlink data request message not to AS40 The errored response of target UE can be sent to.If timestamp and operation execute any earlier than T2 in the time further for example, request is exceeded the time limit, M2M management platforms 20 are default up to the information preset in time list up to the period to AS40 transmissions, indicate AS40 by downlink Timestamp is exceeded the time limit in request in data request information and operation executes after time modification is the reachable time not yet to arrive.
Source parameter due to presetting reachable time list in M2M management platforms is Network, i.e., default to be arranged up to the time Table is synchronous with the PSM timer in network server.So when current time T1 was located within the default reachable period, when Preceding moment T1 is also in network server in the defined Idle status time periods of PSM timer, rather than in network server In the defined PSM periods of middle PSM timer.M2M management platforms send the downlink data request message in T1 to UE, will not So that the PSM periods of UE is reduced, ensures that UE has longer stand-by time.
In some embodiments of the present invention, M2M management platforms 20 can be also used for subscribing to UE10's to network server 30 Idle states；The registration request for receiving UE10, the default information up to the period for the UE10 for including according to registration request is at this Ground is that UE creates default reachable time list；The Idle state reports for receiving the UE that network server 30 returns, according to Idle shapes As default rising up to the period at the time of UE is entered Idle states at the time of the UE that state report includes enters Idle states Begin the moment；And set the default source parameter up to time list to Network.In further embodiments, M2M management is flat Platform 20 can be also used for sending source parameter to UE being the default up to the letter preset in time list up to the period of Network Breath.
In some embodiments of the present invention, M2M management platforms 20 can be also used for receiving second time line number that AS40 is sent According to request message, the second mesh that the identifier lookup of the second target UE for including according to second downstream data request message locally preserves Mark UE second is default up to time list；Determine that the second default source parameter up in time list is equipment Device； It is default up to default up within the period in time list to judge whether current time T3 is located at second；If so, to Two target UE send second downstream data request message.In further embodiments, M2M management platforms 20 are not in T3 Two it is default up to time lists it is default up within the periods when, determine the last message for receiving the second target UE when Carve T4；Judge whether the difference of T3 and T4 is more than the Idle state durations of the second target UE；If being not more than, platform is to the second target UE sends second downstream data request message.In having some embodiments, difference of the M2M management platforms 20 in T3 and T4 is more than the When the Idle state durations of two target UE, the errored response that current second target UE is in inaccessible state is returned to AS.
It should be noted that in the embodiment of the present invention " M2M management platforms send message to UE ", refer to that M2M management is flat Platform sends message by core net to UE.Similarly, " UE send to M2M management platforms message ", refer to UE by core net to M2M management platforms send message.In order to compose a piece of writing conveniently, the following contents of the embodiment of the present invention de-emphasizes.
In conjunction with Fig. 3 or shown in Fig. 4 communication systems, Fig. 5 provides the flow diagram for the method that message is sent to UE, the party Method includes the following steps：
Step 201, the downlink data request message that AS is sent to M2M management platforms, downlink data request message include mesh Mark the mark of UE.
Step 202, M2M management platforms receive the downlink data request message that AS is sent, according to the identifier lookup of target UE The target UE's locally preserved is default up to time list.
This presets default information up to the period that target UE is preserved up to time list, when default reachable about this Between list establishment process at abovementioned steps 105 to step 106 by the agency of, do not repeating herein.
Step 203, M2M management platforms determine that the default source parameter up in time list is network N etwork.
In the embodiment of the present invention, M2M management platforms preserve default up to source parameter is increased in time list, at this When source parameter is Network, indicate that the default default initial time up to the period up in time list takes with network The initial time for the idle Idle status timers being engaged in device for target UE settings is identical, this is default up to time list and network PSM timer in server are synchronized.
Fig. 6 is a kind of schematic diagram of default possible realization method up to time list, wherein the realization method of timetable Table 1 is please referred to, (subscription) is subscribed to and indicates to subscribe to the default network element up to list of thing, example from M2M management platforms Such as one or more marks for subscribing to the default AS up to list of thing.Wherein, digital " 1 " refers to essential project, and this Purpose number is 1, and " L " indicates that the project is list, and digital " 0 " indicates that the project is optional, and " n " indicates the number of the project Can be two or more.
Step 204, it is default up to default reachable in time list to judge whether current time T1 is located at for M2M management platforms Within period；If so, thening follow the steps 205.
Step 205, M2M management platforms send downlink data request message to target UE.
Source parameter due to presetting reachable time list in M2M management platforms is Network, i.e., default to be arranged up to the time Table is synchronous with the PSM timer in network server.So when current time T1 was located within the default reachable period, when Preceding moment T1 is also in network server in the defined Idle status time periods of PSM timer, rather than in network server In the defined PSM periods of middle PSM timer.M2M management platforms send the downlink data request message in T1 to UE, will not So that the PSM periods of UE is reduced, ensures that UE has longer stand-by time.
Step 206, UE receives the downlink data request message, responds the downlink data request message.
UE responds downlink data request message, executes the requested operation of downlink data request message.Optionally, UE is logical It crosses core net and returns to the response message for receiving the downlink data request message to AS.
It is worth noting that step 206 is the introduction done for the integrality of scheme, and it is not to realize the present invention Step necessary to embodiment.
As an alternative embodiment, when determining that current time T1 is not at default reachable by step 204 Between default in list up within the period when, continue to execute following steps：
Step 207, M2M management platforms according to it is default determine up to time list it is next default up to the period after T1 Initial time T2.
Default reachable time list includes 2 or more default reachable periods, is not in current time T1 When the default reachable period, at the time of showing that current time T1 is located at two neighboring preset up between the period, M2M management is put down Platform determines the upcoming next default initial time up to the period, to determine whether next default up to the period Send the downlink data request message.
Step 208, M2M management platforms judge request exceed the time limit timestamp and operation execute the time whether be later than T2.If It is to then follow the steps 209.
Request exceed the time limit timestamp and operation execute the time be AS be downlink data request message setting time limit parameter, In, the request timestamp that exceeds the time limit indicates last effective time of the downlink data request message, exceeds the time limit timestamp under this more than request Row data request information fails.Operation implementation schedule shows the timeliness that the corresponding operation of the downlink data request message is performed, The time is executed more than the operation, the requested operation of downlink data request message will not be executed by UE.
Step 209, M2M management platforms after tl it is next it is default up within the period and exceed the time limit timestamp and The forward direction target UE that operation executes the time sends downlink data request message.
Timestamp is exceeded the time limit in request and operation executes the time and is respectively positioned on next default initial time T2 up to the period Later, show that at least part of period sends downlink data request message symbol to UE within next default reachable period The time limit for closing AE requires.Specifically, if request is exceeded the time limit timestamp and operation execute the time be also later than it is next it is default can Up to the finish time of period, then show that sending downlink data request message to UE within next default reachable period accords with The time limit for closing AE requires；If request is exceeded the time limit, at least one of timestamp and operation execution time can positioned at next preset Up to the initial time of period and between finish time, then exceed the time limit from T2 to request timestamp and operation execute the time in compared with In period between early one the time limit requirement that downlink data request message meets AE is sent to UE.Optionally, M2M is managed Platform sends downlink data request message at the T2 moment to UE, so that UE can receive message in time.
Through the above scheme, M2M management platforms are when current time T1 was not in the default reachable period, Neng Gouwei UE caches the downlink data request message, and next default up within the period and exceeding the time limit timestamp and operation is held The forward direction target UE of row time sends downlink data request message so that UE can receive downlink data request message in time, just The downlink application data of AS transmissions are obtained as early as possible in UE.
As an alternative embodiment, step M2M management platforms judge request exceed the time limit timestamp and operation hold The row time is not when being later than T2, to continue to execute step 210：M2M management platforms return to downlink data request message to AS cannot It is sent to the errored response of target UE.
Due to request exceed the time limit timestamp and operation to execute the time be not to be later than T2, show next default up to the time Section arrive before, the downlink data request message be more than AS setting time limit, and current time T1 to it is next preset it is reachable Period between the initial time T2 of period, UE are in PSM, and M2M management platforms can not be by the downlink data request message It is sent to UE.Therefore, which can not be successfully sent to UE, and M2M management platforms return to lower line number to AS It cannot be sent to the errored response of target UE according to request message, inform that AS downlink datas request message cannot be successfully transmitted.
As an alternative embodiment, step 210 may include that mode is implemented as follows：
If for timestamp earlier than T2, M2M management platforms return to downlink data request message to AS cannot first, request is exceeded the time limit The errored response of target UE is sent to before timestamp is exceeded the time limit in request.
If second, request is exceeded the time limit, timestamp is later than T2 and operation executes the time earlier than T2, M2M management platforms are returned to AS Downlink data request message cannot be sent to the mistake of target UE before operation executes the time.
Since M2M management platforms inform the exact cause that AS downlink datas cannot be sent, downlink data is corrected as convenient for AS Request message setting request exceed the time limit timestamp or operation execute the time, by the request corrected exceed the time limit timestamp or operation execute The downlink data request message of time is sent to M2M management platforms again, and M2M management platforms can be default up to the period It is interior that downlink data request message is sent to UE.
As an alternative embodiment, step M2M management platforms judge request exceed the time limit timestamp and operation hold The row time is not when being later than T2, also to execute step performed below：
Step 211, M2M management platforms are sent default up to the information preset in time list up to the period to AS.
M2M management platforms can be sent to AS indicates default up to all default letters up to the period in time list Breath can also only send the information for indicating next reachable period to AS.
Step 212, when AS exceeds the time limit the request in downlink data request message according to the default information up to the period Between stab and operation executes after time modification is the reachable time not yet to arrive, and exceed the time limit timestamp and operation will be had modified It executes time downlink data request message and is sent to UE again.
Request can be exceeded the time limit timestamp by AS and operation execute the time be disposed as being located at it is next default up to the time After the finish time of section, M2M management platforms can then ask downlink data in any time in next preset time period Message is asked to be sent to UE.Request can also be exceeded the time limit timestamp by AS and operation execute the time be disposed as being located at it is next default Up to the period initial time T2 and between finish time, then M2M management platforms can be in the timestamp that exceeds the time limit from T2 to request And operation executes in the time in the period between one earlier and sends downlink data request message to UE.
This optional embodiment can when downlink data request message cannot be sent to target UE by M2M management platforms, By the default information up to the period for sending UE to AS so that AS changes the time limit parameter in downlink data request message, So that M2M management platforms can send out the downlink data request message for having modified time limit parameter up in the period default Give UE.
It should be noted that above-mentioned steps 211 can be performed simultaneously with step 210, or executed after first carrying out step 210 Step 211, or after first carrying out 211 step 210 is executed.
Fig. 7 is the flow diagram for the synchronous method that another embodiment of the present invention provides, which includes as follows Step：
Step 301, Idle state of the M2M management platforms to network server objective of subscription UE.
As an example, in communication system shown in Fig. 4, M2M management platforms by providing in advance for M2M management platforms External identifiers (External Identifier) or mobile station comprehensive service digital net number (Mobile Station Integrated Services Digital Network Number, MSISDN) call api interface that UE is set to SCEF The subscription information of Idle states.SCEF is sent to HSS/MME by S6t interfaces, by the subscription information of the UE Idle states, HSS/MME is according to the Idle states that the subscription information of the UE Idle states is that M2M management platforms subscribe to UE, in UEConnected State sends the Idle state reports of UE to M2M management platforms when switching to Idle states.
Step 302, M2M management platforms receive the registration request of target UE, and registration request includes the default reachable of target UE The information of period.
Step 302 can execute after step 301, can also be executed before step 301, the embodiment of the present invention is refused It limits.
Step 303, M2M management platforms are being locally that target UE creates default reachable time list, preset and are arranged up to the time Table includes default up to the period in registration request.
Step 304, when network server detects that UE switches to Idle states from Connected states, generate UE's Idle state reports, and the Idle state reports are sent to M2M management platforms.The Idle state reports include the mark of target UE At the time of knowledge and target UE enter Idle states.
The embodiment of the present invention makes improvement to the parameter of the communication interface in network server, with by communication interface to M2M management platforms send the information in above-mentioned Idle state reports.For example, by taking structure shown in Fig. 4 as an example, MME and SCEF it Between the interface that is communicated between the interface that communicates and SCEF and M2M management platforms increase " UE-Idle-Timestamp " parameter, At the time of entering Idle states for carrying the target UE, and then realize that MME sends the target UE to SCEF and enters Idle At the time of state and at the time of SCEF enters Idle states to the M2M management platforms transmission target UE.
Step 305, M2M management platforms carry out the more default reachable time list locally preserved according to Idle state reports Newly.
M2M management platforms are the default reachable of target UE establishments according to the mark location of the target UE in Idle state reports Time list, as the default initial time up to the period at the time of target UE is entered Idle states.
Since M2M management platforms generate default reachable time list according to the default information up to the period that UE is sent, And the adjacent default time interval up between the period is equal to UE and net in the default information up to the period that UE is sent The location updating period in the PSM timer parameters that network server is negotiated, and each default duration up to the period is equal to Idle state durations in PSMtimer parameters.It can up to adjacent preset in time list so being preset in M2M management platforms It is equal to the location updating period for the PSM timer defineds being arranged in network server, M2M up to the time interval between the period It presets to be equal to up to the duration each preset in time list up to the period in management platform and be arranged in network server The Idle state durations of PSMtimer defineds.Therefore, as long as M2M management platforms are made at the time of target UE is entered Idle states For the default initial time up to the period, you can be arranged in the default reachable time list of realization and network server PSMtimer is synchronized.
Step 306, M2M management platforms set the default source parameter up to time list to Network.
M2M management platforms will it is default up to time list it is synchronous with the PSM timer being arranged in network server after, general The default source parameter up to time list is set as Network, with show it is default up to time list with network service The PSM timer being arranged in device are synchronized.M2M management platforms are sent to the downlink data request message of UE receiving AS requests Afterwards, you can 203 to step 211 determine when the downlink data request message being sent to UE through the above steps, ensure UE's PSM durations are not reduced.
As an alternative embodiment, in step 305, M2M management platforms are also by PSM timer parameters Idle states duration, location updating period are updated to default up to time list.Specifically, M2M management platforms are by target At the time of at the time of UE enters Idle states plus Idle state durations, as it is default up in time list it is default up to when Between section finish time；And using the location updating period as it is default up in time list it is adjacent it is default up to the period it Between time interval.
Wherein, M2M management platforms can obtain Idle states duration and location updating period through a variety of ways, packet It includes：
First, network server generate Idle state reports further include target UE Idle states duration and position more New period, M2M management platforms obtain Idle states duration and location updating period from the Idle state reports of reception.
By taking structure shown in Fig. 4 as an example, between the interface and SCEF and M2M management platforms that are communicated between MME and SCEF The interface of communication increases parameter for carrying the Idle states duration and for carrying the location updating period Parameter, and then realize that MME sends the Idle states duration and the location updating period and SCEF to M2M to SCEF Management platform sends the Idle states duration and the location updating period.
Second, the PSM timer of UE are arranged by M2M management platforms for UE in network server, and therefore, M2M management platforms The parameters such as Idle states duration and the location updating period of PSM timer in network server are preserved, M2M management platforms can To read the above-mentioned parameter locally preserved.
Although M2M management platforms, when creating default reachable time list, the default duration up to the period is equal to Idle state durations in PSMtimer parameters, the adjacent default interval up between the period are equal in PSM timer parameters The location updating period, still, M2M management platforms are after receiving Idle state reports, still through in PSM timer parameters Idle states duration, location updating period are updated to default up to time list, and the mistake due to being likely to occur is avoided to lead Cause default duration and Idle state durations up to the period inconsistent or adjacent default interval and position up between the period It is inconsistent to set the update cycle, it is ensured that default synchronous with the PSM timer being arranged in network server up to time list.
Further include following steps after step 306 as a kind of optional realization method：
Step 307, M2M management platforms send source parameter to target UE and are set as the default up to time row of Network The information up to the period is preset in table.
The so-called default information up to the period can be default reachable time list itself, can also be only to indicate reachable The information up to the period is preset in time list.M2M management platforms by locally preserve it is default up to time list with After PSM timer in network server are synchronized, sent default up to the information preset in time list up to the period To UE, so that the default reachable period that UE is locally preserved according to the default information update UE up to the period.
Step 308, UE receives the default information up to the period that M2M management platforms are sent, and default according to reception can It is locally preserved up to the information update of period default up to the period.
The reachable period that UE is locally preserved be used to indicate UE this up in the period keep Idle states, so as to UE energy It is enough default up to the downlink data request message that reception M2M management platforms may be sent in the period at this.
The default information up to the period sent to UE due to M2M management platforms in network server PSMtimer is synchronized, so the reachable period that UE is locally preserved is synchronous with the PSM timer in network server, UE is according to this The time for holding of the reachable period Idle states that ground preserves, the UE as defined in PSM timer in network server was in Idle shapes In the period of state, rather than UE as defined in PSM timer was within the period of PSM in network server, was avoided UE is kept for the PSM periods of UE caused by Idle states reduce in the PSM periods as defined in PSM timer, ensures that UE has Longer stand-by time.
As a kind of optional realization method of all embodiments in front, referring to Fig. 8, method provided in an embodiment of the present invention Further include following steps：
Step 401, AS sends second downstream data request message, second downstream data request message to M2M management platforms Include the mark of the second target UE.
Step 402, M2M management platforms receive the second downstream data request message that AS is sent, according to the second target UE's The second of the second target UE that identifier lookup locally preserves is default up to time list.
Step 403, M2M management platforms determine that the second default source parameter up in time list is equipment Device.
Second target UE sends when presetting reachable of the second target UE when M2M management platforms are registered, to M2M management platforms Between section information, M2M management platforms are that the second target UE is created according to the default information up to the period of second target UE It is default to be set as Device up to time list, and by the default source parameter up to time list, show that this is default reachable It presets in time list and is determined by UE up to the period.
Step 404, it is default up to default in time list to judge whether current time T3 is located at second for M2M management platforms Up within the period.If so, thening follow the steps 405.
Step 405, M2M management platforms send second downstream data request message to the second target UE.
Since when the second default source parameter up to time list is set as Device in M2M management platforms, M2M is managed It is consistent with the default reachable period that the second target UE is locally preserved that the reachable period is preset in platform, so being managed in M2M At the time of presetting up in the period in platform, UE is default up to period holding Idle states according to what is locally preserved.M2M is managed Default reachable period of the platform in the second default reachable time list sends downlink data request message to UE, and UE locates In Idle states, ensure that UE being capable of downlink data request message timely, that the transmission of M2M management platforms is correctly received.
It is default up to time row determining that T3 is not at second by step 404 as a kind of optional realization method Further include following steps when within the default reachable period of table：
Step 406, T4 at the time of M2M management platforms determine the last message for receiving the second target UE.
M2M management platforms record, which has, receives the historical record that the second target UE sends upstream message, or only record is nearest The record of the primary upstream message for receiving the second target UE, M2M management platforms are determined according to above-mentioned record the last receives the The T4 at the time of message of two target UE.
Step 407, M2M management platforms judge whether the difference of T3 and T4 is more than the Idle state durations of the second target UE； If being not more than, 408 are thened follow the steps.
Due to the second default time interval etc. up between the adjacent reachable period in time list in M2M management platforms In the Idle state durations of the second target UE, so, M2M management platforms can be default up to adjacent in time list according to second The Idle state durations of second target UE are determined up to the time interval between the period.Alternatively, M2M management platforms can adopt In various ways when obtaining the Idle states of target UE with M2M management platforms in preceding step 305 secondly the side introduced Formula obtains the Idle state durations of second target UE, is not repeated herein.
Step 408, M2M management platforms send second downstream data request message to the second target UE.
Fig. 1 is please referred to, UE to M2M management platforms in Connected states after sending upstream message, if on not Row data transfer demands can then be switched to Idle states by Connected states, and therefore, M2M management platform the last times receive It is differed very at the time of T4 switches to Idle states with the second target UE by Connected states at the time of the message of second target UE Small, the two deviation can be ignored.In the embodiment of the present invention, M2M management platforms by the T4 be considered as the second target UE by At the time of Connected states switch to Idle states.
When the difference of the current time T3 and T4 is not more than the Idle state durations of the second target UE, M2M management platforms It can determine time interval at the time of current time T3 distance the second target UE is switched to Idle states by Connected states The Idle state durations for not yet exceeding the second target UE show current time T3 still in the PSM timer rule of network server Within fixed Idle status time periods.M2M management platforms send second downstream data request at the T3 moment to the second target UE Message can not only make the second target UE receive the second downstream data request message in time.Moreover, because M2M management is flat T3 is as defined in the PSM timer of network server at the time of platform sends the second downstream data request message to the second target UE Within Idle status time periods, rather than within the PSM periods as defined in the PSM timer of network server, therefore, in M2M management platforms send the second downstream data request message to the second target UE will not lead to the PSM times of the second target UE Section is reduced, and ensures that the second target UE has longer stand-by time.
As a kind of optional realization method, determining the difference of T3 and T4 more than the second target UE's by step 407 Further include step 409 when Idle state durations：M2M management platforms return to current second target UE to AS and are in inaccessible state Errored response.
