Description

Based on attachment removal flow process, upgrade method and the device of accessible state of terminal information
Technical field
The present invention relates to the communications field, particularly a kind of method and device that upgrades accessible state of terminal information based on attachment removal flow process.
Background technology
In 3GPP TS22.368 machine type communication demand for services standard, SA1 has proposed terminal and has triggered MTC characteristic, be that network should be able to be based on MTC Server(Machine Type Communication, machine type communication server) the triggering indication sending, triggers MTC Device(MTC terminal) initiate with MTC Server between communicate by letter.
In actual applications, MTC terminal may comprise with the situation of communicating by letter between MTC Server from network reception triggering indication foundation:
When MTC terminal offline(off-line) time receive to trigger indication;
When MTC terminal, online(is online) but receive when not setting up data and connecting and trigger indication;
When MTC terminal online built vertical data connection, receive and trigger indication.
With regard to current SA2 discusses result, corresponding to 3GPP network system, off-line refer to terminal at 3GPP network in attachment removal state, refer to that online terminal is in attachment state, data connection refers to the PDP(Packet Data Protocol that terminal is set up in 3GPP network, packet data protocol) context/PDN(Packet Data Network, packet data network) connect.
According to the demand, 3GPP network system needs to receive the triggering indication that MTC Server sends, and in MTC terminal in attachment removal state, adhere to but without PDP/PDN connection status, and in adhering to and having in any one situation in PDP/PDN connection status, to MTC terminal initiate to trigger make its set up with MTC Server between communicate by letter.
3GPP network can take various ways to send and trigger indication to MTC terminal.Transparent to MTC Server in order to make to trigger the transfer process of indication in 3GPP network, SA2 proposes to increase MTC-IWF(MTC-Inter Working Function at 3GPP network edge at present, interworking function entity) method shields the detail of 3GPP network, for MTC Server provides unified interface and service, specifically as shown in Figure 1.Based on this framework, regardless of the reachable state of MTC terminal, MTC Server can both initiate trigger request to 3GPP network by a single interface protocol.
MTC-IWF has DT(Device Trigger, and terminal triggers) function, after the triggering indication that receives MTC Server transmission, MTC-IWF further sends to trigger to MTC terminal by 3GPP network and indicates.The transmission means that triggers indication in 3GPP network is including but not limited to several as follows:
Utilize the PDP Context/PDN having set up to connect, by GGSN(Gateway GPRS Support Node)/P-GW(PDN gateway) transmit;
The PDP context activation request flow process of initiation Network Based, utilizes newly-established PDP Context to transmit by GGSN;
Utilize SIP(session initiation protocol)/IMS(IP IP multimedia subsystem, IMS) serve by S-CSCF(serving session control function entity) transmission;
Utilize SMS(short message) by SMS-SC(short message service service centre) transmission;
Utilize CBS(cell broadcast service), by CBC broadcasting transmitting.
Face many optional triggering modes, after receiving a triggering Indication message, first MTC-IWF needs the current residing Reachability Information(reachable state of based target MTC terminal), for triggering Indication message, determine the most effectively transmission means, wherein, the reachable state of MTC terminal also can be described as attachment state, be used for representing whether terminal is attached to network, and whether set up data connection after adhering to; Then, MTC-IWF re-constructs the triggering Indication message receiving from MTC Server for the information format corresponding with selected transmission means and sends it to corresponding network entity, thereby realizes the triggering of MTC terminal.
Except above-mentioned, by introducing MTC-IWF shielding 3GPP Internet Transmission details, realize the method for MTC terminal triggering, also proposed many triggering method for the MTC terminal in a certain reachable state at present.These methods mostly directly send triggering Indication message to 3GPP network entity by MTC Server and initiate the triggering flow process of network to MTC terminal.According to the difference of the residing reachable state of MTC terminal, MTC Server can select different modes to trigger.For example, for the terminal of attachment removal, can pass through CBS(Cell Broadcast Service, cell broadcast service), SMS(Short Message Service, Short Message Service) etc. mode trigger; For adhering to but do not set up the MTC terminal that PDP Context/PDN connects, request, NAS(Non Access Stratum, Non-Access Stratum are set up in the connection that MTC Server can initiate by network) message, the modes such as SMS trigger; For the terminal of adhering to and built vertical PDP Context/PDN connects, can pass through IMS, the modes such as SMS trigger.Yet before the selection of doing concrete transmission means, MTC Server need to first obtain the reachable state information of MTC terminal, i.e. attachment state information.
For the functional requirement that triggers MTC terminal, no matter that by MTC-IMF Contact, to return be directly to trigger by MTC Server, the common issue that network-side service node (MTC-IMF or MTC Server) faces is: how to obtain the current reachable state information of target MTC terminal, only has this information that obtained, network-side service node could determine concrete transmission means, thereby initiates the triggering flow process of MTC terminal.
In order to address the above problem, at present, Home Location Register has been proposed in existing technical scheme based on HLR()/HSS(home subscriber servers) obtain the solution of the reachable state information of MTC terminal.In this scheme, suppose that HLR/HSS can preserve and safeguard the reachable state information of MTC terminal.The network-side service node of take is that MTC-IWF is example, MTC-IWF determines the HLR/HSS under MTC terminal by DT function according to the identify label that triggers the MTC terminal comprising in Indication message, and by C/Sh interface to the current reachable state information of HLR/HSS inquiry MTC terminal.When receiving the inquiry request of MTC-IWF, HLR/HSS returns to the current reachable state information of MTC terminal to MTC-IWF; Wherein, here, the reachable state information that HLR/HSS obtains MTC terminal is the correct prerequisite of carrying out of follow-up flow process.
In 3GPP TS23060/23.401, define the attach operation flow process of MTC terminal, for network service node, by HLR/HSS, obtained the reachable state information of MTC terminal.When the MTC terminal of having adhered to no longer needs service that 3GPP network provides or 3GPP network no longer to provide service for the MTC terminal of having adhered to, MTC terminal or network will be initiated detach(attachment removal) flow process makes MTC terminal disengaging network.
According to detach promoter's difference, detach flow process can be divided into: the detach flow process that the detach flow process that MTC terminal is initiated and network side are initiated.Wherein, the latter can be subdivided into again: the detach flow process that the detach flow process that SGSN/MME initiates and HLR/HSS initiate.Or initiate the difference of mode according to detach, detach flow process can be divided into: the detach flow process explicit attachment removal of Explicit detach() and the attachment removal of Implicit detach(implicit expression) detach flow process; So-called explicit attachment removal refers to, network side or MTC terminal send Detach Request(detach request by explicitly) mode of message initiates attachment removal flow process, and so-called implicit expression attachment removal refers to, when attachment removal condition meets, network side will carry out attachment removal and MTC terminal do not carried out to any notice MTC terminal.
MTC terminal is being attached to GPRS(General Packet Radio Service, general packet radio service technology) in the situation of network, the detach flow process of initiating for MTC terminal, according to the difference of detach network type, detach flow process can be divided into: IMSI(International Mobile SubscriberIdentification Number, international mobile subscriber identity) detach(IMSI attachment removal), GPRS detach(GPRS attachment removal) and combined GPRS/IMSI detach(GPRS/IMSI associating attachment removal).IMSI detach departs from from CS territory network for MTC terminal, and GPRS detach provides the PS territory network disengaging combined GPRS/IMSI detach of service from PS/CS territory network, to depart from for MTC terminal for MTC terminal from SGSN simultaneously.
MTC terminal is in the situation that be attached to the grouping system of EPS(evolution) network, the detach flow process of initiating for MTC terminal, according to the difference of detach network type, detach flow process can be divided into: IMSI detach(IMSI attachment removal), and EPS detach(EPS attachment removal) and combined EPS/IMSI detach(EPS/IMSI associating attachment removal).IMSI detach departs from from CS territory network for MTC terminal, and EPS detach provides the PS territory network of service to depart from for MTC terminal from MME, and combined EPS/IMSI detach departs from from PS/CS territory network for MTC terminal simultaneously.
At ISR(Idle mode Signaling Reduction, idle state signaling reduces) in mechanism situation about activating, MTC terminal, by be registered to GRPS and EPS network simultaneously, provides service by MME/SGSN and SGSN/MME for it.At this moment, in detach flow process, MME/SGSN will send Detach Notification(attachment removal notice to the other side SGSN/MME) message, to it, indicating detach flow process is local detach or complete is detach; And when MME/SGSN initiates implicit expression attachment removal flow process, MME/SGSN will be local detach to the other side SGSN/MME indication detach flow process, now, the other side SGSN/MME will keep the attachment state of MTC terminal constant, only have when detach flow process is complete detach, the other side SGSN/MME is also by the attachment removal of MTC terminal.
According to the relevant regulations of 3GPP TS23060/23.060, in above-mentioned all kinds of attachment removal handling process, except the detach flow process of being initiated by HLR/HSS, for other attachment removal flow processs, when terminal is from network during attachment removal, SGSN/MME does not carry out alternately with HLR/HSS, and HLR/HSS can not be known the change of accessible state of terminal like this.
The existing method based on HLR/HSS requires HLR/HSS can preserve the up-to-date information relevant to accessible state of terminal.Yet, according to the handling process of existing protocol, except the detach flow process that HLR/HSS initiates, when MTC terminal is from network during attachment removal, SGSN/MME does not carry out alternately with HLR/HSS, this means that, when MTC terminal transfers attachment removal state to by attachment state in 3GPP network, the reachable state information of MTC terminal (also referred to as attachment state information) is not upgraded at HLR/HSS place; Like this, by the method for inquiry HLR/HSS, in fact network-side service node can not obtain the up-to-date reachable state information of MTC terminal in time, thereby makes network-side service node be difficult to select correct triggering mode to trigger MTC terminal, and then has affected the follow-up operation of whole system.

Embodiment
For make signing location server (as, HLR/HSS) obtain in time MTC terminal reachable state information accurately, thereby guarantee that MTC terminal triggers the correct execution of flow process, in the embodiment of the present invention, has adopted following solution:
At HLR/HSS place, in MTC terminal context, safeguard the reachable state information of MTC terminal, this information at least comprises the attachment state of MTC terminal, is recording the current network that whether is attached to of MTC terminal, specifically as shown in table 1:
Table 1
Further, in the reachable state information of MTC terminal, also can comprise the type of attachment information of MTC terminal, specifically as shown in table 2:
Table 2
Wherein, MTC terminal accompanying network type is including but not limited to CS territory network, GPRS PS territory network, EPS(evolved packet system) network.
When confirming that MTC terminal is from network during attachment removal, core network control node (as, SGSN/MME) to HLR/HSS, send the state update request message of the attachment removal type information that at least carries MTC terminal, the attachment removal from network of indication MTC terminal, now, the reachable state information that HLR/HSS preserves according to the local corresponding MTC terminal of the state update request information updating receiving, for example, the attachment removal type information that can carry according to this state update request message upgrades the type of attachment information that corresponding MTC terminal is preserved, finally, HLR/HSS will upgrade response message to core network control node return state and reply.
State update request message and state upgrade response message by the Gr/S6a/S6d interface between SGSN/MME and HLR/HSS based on MAP(Mobile Application Part, MAP agreement) agreement (while adopting Gr interface) or Diameter (while adopting S6a/S6d interface) transmission.When specific implementation, state update request message and state upgrade response message and can adopt the message of new definition to realize transmission, also can realize transmission by increase the mode of information unit in existing protocol message.
Wherein, SGSN and HLR represent is that what for 3G network application scenarios, MME and HSS in 3GPP network, to represent is for the EPS network application scene in 3GPP network, and in " SGSN/MME " and " HLR/HSS ", "/" represent " or/and " relation, because MTC terminal can be registered to two kinds of core networks simultaneously, adopt two kinds of core net network formats, all like this in subsequent descriptions.
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is elaborated.
In the embodiment of the present invention, the first core network control node (as, SGSN/MME) confirm that MTC terminal is from network during attachment removal, the signing location server of notice (as, the reachable state information of HLR/HSS) corresponding MTC terminal being preserved is carried out corresponding renewal; Consult shown in Fig. 2, it is as follows that flow process is carried out in the general introduction of this flow process:
Step 200:SGSN/MME confirms the attachment removal from network of MTC terminal.
In the present embodiment, performing step at 200 o'clock, detach request message authentication MTC terminal attachment removal from network that SGSN/MME can initiatively send according to MTC terminal; Or SGSN/MME also can, when definite network side no longer provides related service to MTC terminal, confirm this MTC terminal attachment removal from network, be that SGSN/MME is initiatively by the attachment removal of MTC terminal, now, SGSN/MME can, by attachment removal operational notification MTC terminal, can not notify yet.
The reachable state information that step 210:SGSN/MME notice HLR/HSS preserves corresponding MT reconnaissance C terminal is carried out corresponding renewal.
Be specially: when confirming that MTC terminal is from network after attachment removal, SGSN/MME sends the state update request message of the attachment removal Status Type information of at least carrying this MTC terminal to HLR/HSS, the current attachment state of indication MTC terminal changes, HLR/HSS obtains and upgrades the reachable state information of corresponding MT reconnaissance C terminal according to the state update request message receiving, for example, can be according to the reachable state information shown in table 1, according to the state update request message receiving, the current attachment state of MTC terminal is upgraded, again for example, also can be according to the reachable state information shown in table 2, according to the state update request message receiving, the current attach to network type of MTC terminal and corresponding attachment state are upgraded.
Based on above-described embodiment, in practical application, if activated ISR mechanism in system, mean that MTC terminal is registered to two core network control nodes that adopt different 3GPP network formats simultaneously, for example, be registered to SGSN and MME simultaneously, now, SGSN and MME can be considered binding relationship, so, a core network control node in two core network control nodes of binding (as, SGSN/MME) determine that MTC terminal is from network during attachment removal, should to binding another core network control node (as, MME/SGSN) notice MTC terminal attachment removal from network, its reason can be " Complete ", it is complete attachment removal, also can be " Local ", it is local attachment removal.MME/SGSN should process accordingly, and concrete details of operation will describe in detail in subsequent embodiment.
Based on above-described embodiment, four kinds of different enforcement scenes are carried out respectively to corresponding introduction below.
Consult shown in Fig. 3, in the first situation, by increase state in the attachment removal flow process of initiating in MTC terminal, upgrade operation, provided the update method of the MTC accessible state of terminal information that is applicable to 3GPP network, wherein, existing operation to attachment removal flow process is simple to some extent, (corresponding to the unactivated situation of ISR mechanism) specific as follows:.
Step 300: when MTC terminal need to depart from network, send detach request message to SGSN/MME.
In the detach request message that MTC terminal sends, need to indicate the network type of attachment removal, carry the attachment removal type information of MTC terminal.For example, the network type of the MTC terminal attachment removal that detach request message is indicated can be: IMSI attachment removal, GPRS attachment removal, EPS attachment removal, GPRS/IMSI associating attachment removal, EPS/IMSI associating attachment removal.
Step 310:SGSN/MME carries out attachment removal relevant treatment according to existing protocol, and to MTC terminal, returns to adhere to as required and accept message and respond.
In practical application, for fear of the unnecessary signaling of transmission, SGSN/MME also can not return to adhere to MTC terminal and accept message, for example, when SGSN/MME determines MTC terminal because of shutdown attachment removal, can to MTC terminal, not send attachment removal and accept message.
Step 320: after receiving detach request message, SGSN/MME sends state update request message to HLR/HSS, notifies the attachment state of MTC terminal to change to HLR/HSS.
In state update request message, at least need to carry the attachment removal type information of MTC terminal, be used to indicate the network type of the attachment removal of MTC terminal, for example, in state update request message, can comprise: the identification information of MTC terminal (as, IMSI, MSISDN(Subscriber ISDN Number, mobile subscriber ISDN number) etc.), the attachment removal type information of MTC terminal etc.
For example, consult shown in table 3, on SGSN/MME, preserve mapping relations information as shown in table 3, attachment removal type information in the detach request message that SGSN/MME need to send according to MTC terminal is determined the attachment removal type information that needs the MTC terminal of carrying in state update request message according to the content shown in table 3, and the reachable state information as shown in table 1 or table 2 of corresponding MTC terminal being preserved by this state update request message informing HLR/HSS is carried out corresponding renewal, wherein, although what SGSN was corresponding is GPRS network application scenarios, but also MTC terminal can be upgraded by the attachment removal advisory HLR for CS network, in like manner, although what MME was corresponding is EPS network application scene, but also MTC terminal can be upgraded by the attachment removal advisory HSS for CS network.
Table 3
Step 330:HLR/HSS is according to the attachment removal type information of the MTC terminal of carrying in state update request message, and the reachable state information that corresponding MTC terminal is preserved is carried out corresponding renewal, and upgrades response message to SGSN/MME return state.
Be specially: SGSN/MME can be according to mapping relations information as shown in table 3, the attachment removal type information of MTC terminal is carried in state update request message and is sent to HLR/HSS, HLR/HSS is in the reachable state information of the contextual information record of MTC terminal, attachment removal type information according to the MTC terminal receiving from SGSN/MME, is designated as " attachment removal " by the attachment state of MTC terminal attachment removal network; Afterwards, HLR/HSS will upgrade the successful renewal that response message is confirmed the reachable state information of MTC terminal to SGSN/MME return state.
Further, in the information as shown in table 2 that corresponding MTC terminal is preserved, having recorded MTC terminal is attachment removal state at GPRS PS territory network or EPS network, and when CS territory network is attachment removal state, HLR/HSS will be designated as " attachment removal " the attachment state of MTC terminal as shown in table 1.Table 1?
Consult shown in Fig. 4, in the second situation, same by increase state renewal operation in the attachment removal flow process of initiating in MTC terminal, provided the update method of the MTC accessible state of terminal information that is applicable to 3GPP network, wherein, existing operation to attachment removal flow process is simple to some extent, and whether SGSN/MME need to adopt different processing modes according to the activation of ISR mechanism, specific as follows:
Step 400: when MTC terminal need to depart from network, send detach request message to SGSN/MME.
In the detach request message that MTC terminal sends, need to indicate the network type of attachment removal, carry the attachment removal type information of MTC terminal.For example, the network type of the MTC terminal attachment removal that detach request message is indicated can be: IMSI attachment removal, GPRS attachment removal, EPS attachment removal, GPRS/IMSI associating attachment removal, EPS/IMSI associating attachment removal.
Step 410:SGSN/MME judges whether ISR mechanism activates, and another MME/SGSN if so, simultaneously registering to MTC terminal sends attachment removal notification message; Otherwise, according to step 310-step 330, carry out relevant treatment; In the present embodiment, take and activate ISR mechanism and carry out related description as example.
In step 410, another MME/SGSN that SGSN/MME registers to MTC terminal simultaneously sends attachment removal notification message and refers to, if MTC terminal sends detach request message to SGSN, the MME that SGSN registers to MTC terminal simultaneously sends attachment removal notification message, if MTC terminal sends detach request message to MME, the SGSN that MME registers to MTC terminal simultaneously sends attachment removal notification message, all like this in subsequent embodiment, repeats no more.
When another MME/SGSN simultaneously registering to MTC terminal as SGSN/MME sends attachment removal notification message, can notify the other side's attachment removal former because " Complete ", or, be " Local ", conventionally, when MTC terminal is initiatively from network during attachment removal, attachment removal the all-network that MTC terminal need to be adhered to from it, now, attachment removal reason is " Complete ", and can not communicate with MTC terminal within the time period that SGSN/MME is setting, SGSN/MME also should be by the attachment removal of MTC terminal, now, attachment removal reason is " Local ", under latter event, MTC terminal probably can also communicate with MME/SGSN, therefore, preferably, SGSN/MME should be by local attachment removal operational notification MME/SGSN, and MME/SGSN still keeps MTC terminal at its local attachment state.
Step 420:MME/SGSN carries out attachment removal relevant treatment according to existing protocol, and returns to and adhere to acknowledge message and respond to SGSN/MME.
Step 430:SGSN/MME carries out attachment removal relevant treatment according to existing protocol, and to MTC terminal, returns to adhere to as required and accept message and respond.
In practical application, for fear of the unnecessary signaling of transmission, SGSN/MME also can not return to adhere to MTC terminal and accept message, for example, when SGSN/MME determines MTC terminal because of shutdown attachment removal, can to MTC terminal, not send attachment removal and accept message.
Step 440:SGSN/MME sends state update request message to HLR/HSS, to HLR/HSS, notifies the attachment state of MTC terminal to change.
In state update request message, at least need to carry the attachment removal type information of MTC terminal, be used to indicate the network type of the attachment removal of MTC terminal, for example, in state update request message, can comprise: the identification information of MTC terminal (as, IMSI, MSISDN etc.), attachment removal type information of MTC terminal etc.
For example, consult shown in table 3 and table 4, on SGSN/MME, preserve the mapping relations information as shown in table 3 or table 4, attachment removal type information in the detach request message that SGSN/MME need to send according to MTC terminal is determined the attachment removal type information that needs the MTC terminal of carrying in state update request message according to the content shown in table 3 or table 4, wherein, when the un-activation of ISR mechanism (as shown in Figure 3), SGSN/MME only need to carry out map operation according to the content shown in table 3, and when ISR mechanism activates (as shown in Figure 4), SGSN/MME can carry out map operation according to the content shown in table 3, also can carry out map operation according to the content shown in table 4, in the present embodiment, situation about activating for ISR mechanism, the table 3 of first take describes as example.
Table 3
Table 4
Step 450:HLR/HSS is according to the attachment removal type information of the MTC terminal of carrying in state update request message, and the reachable state information that corresponding MTC terminal is preserved is carried out corresponding renewal, and upgrades response message to SGSN/MME return state.
Be specially: SGSN/MME can be according to mapping relations information as shown in table 3, the attachment removal type information of MTC terminal is carried in state update request message and is sent to HLR/HSS, HLR/HSS is in the reachable state information of the context record of MTC terminal, attachment removal type information according to the MTC terminal receiving from SGSN/MME, is designated as " attachment removal " by the attachment state of MTC terminal attachment removal network; Afterwards, HLR/HSS will upgrade the successful renewal that response message is confirmed the reachable state information of MTC terminal to SGSN/MME return state.
Further, in the information as shown in table 2 that corresponding MTC terminal is preserved, having recorded MTC terminal is attachment removal state at GPRS PS territory network or EPS network, and when CS territory network is attachment removal state, HLR/HSS will be designated as " attachment removal " the attachment state of MTC terminal as shown in table 1.
Step 460: after receiving attachment removal notification message, MME/SGSN sends state update request message to HLR/HSS, notifies the attachment state of MTC terminal to change to HLR/HSS.
In state update request message, at least need to carry the attachment removal type information of MTC terminal, be used to indicate the network type of the attachment removal of MTC terminal, for example, in state update request message, can comprise: the identification information of MTC terminal (as, IMSI, MSISDN etc.), attachment removal type information of MTC terminal etc.If the state update request message recording in this step is the MME in network, send, the attachment removal type of MTC terminal is: the attachment removal of EPS network; If the state update request message recording in this step is the SGSN in GPRS network, send, the attachment removal type of MTC terminal is: the network attachment removal of GPRS PS territory.
Step 470:HLR/HSS is according to the attachment removal type information of the MTC terminal of carrying in state update request message, and the reachable state information that corresponding MTC terminal is preserved is carried out corresponding renewal, and upgrades response message to MME/SGSN return state.
Be specially: MME/SGSN is carried at the attachment removal type information of MTC terminal in state update request message and is sent to HLR/HSS, HLR/HSS is in the reachable state information of the contextual information record of MTC terminal, attachment removal type information according to the MTC terminal receiving from MME/SGSN, is designated as " attachment removal " by the attachment state of MTC terminal attachment removal network; Afterwards, HLR/HSS will upgrade the successful renewal that response message is confirmed the reachable state information of MTC terminal to MME/SGSN return state.
Further, in the information as shown in table 2 that corresponding MTC terminal is preserved, having recorded MTC terminal is attachment removal state at GPRS PS territory network or EPS network, and when CS territory network is attachment removal state, HLR/HSS will be designated as " attachment removal " the attachment state of MTC terminal as shown in table 1.
Based on above-described embodiment, in the situation that ISR mechanism activates, in step 440, SGSN/MME also can be according to mapping relations information as shown in table 4, the attachment removal type information of MTC terminal is carried in state update request message and is sent to HLR/HSS, HLR/HSS is in the reachable state information of the contextual information record of MTC terminal, and the attachment removal type information according to the MTC terminal receiving from SGSN/MME, is designated as " attachment removal " by the attachment state of MTC terminal attachment removal network; Now, HLR/HSS has completed the renewal of the attachment state of MTC terminal, and therefore, MME/SGSN is when receiving the attachment removal notification message of SGSN/MME transmission, without again sending state update request message to HLR/HSS again, only need be in its this locality by the attachment removal of MTC terminal.
In the above-described embodiments, SGSN/MME can carry the attachment removal reason of MTC terminal in the attachment removal notification message sending to MME/SGSN,
For example, in the present embodiment, owing to being the initiatively attachment removal of MTC terminal, SGSN/MME is former because " Complete " to the attachment removal of MME/SGSN notice, so, if SGSN/MME sends state update request message according to the mapping relations information shown in table 4 to HLR/HSS, MME/SGSN is when receiving the attachment removal notification message of SGSN/MME transmission, in this locality by the attachment removal of MTC terminal, without send state update request message to HLR/HSS; If SGSN/MME sends state update request message according to the mapping relations information shown in table 3 to HLR/HSS, the mode that MME/SGSN still records according to step 460 sends state update request message to HLR/HSS.
Again for example, suppose that SGSN/MME can not communicate with MTC terminal within the scope of setting-up time, SGSN/MME is former because " Local " to the attachment removal of MME/SGSN notice, so, MME/SGSN can not send state update request message to HLR/HSS, but in this locality by the deexcitation of ISR mechanism, and still keep the attachment state of MTC terminal.
Consult shown in Fig. 5, in the third situation, by increase state in the attachment removal flow process of initiating at network side, upgrade operation, provided the update method of the MTC accessible state of terminal information that is applicable to 3GPP network, wherein, existing operation to attachment removal flow process is simple to some extent, (corresponding to the unactivated situation of ISR mechanism) specific as follows:
When step 500:SGSN/MME confirms that network side no longer provides related service for MTC terminal, to MTC terminal, send detach request message.
In practical application, according to the regulation of related protocol, SGSN/MME can adopt explicit way or implicit by the attachment removal of MTC terminal, when adopting explicit way, SGSN/MME can send detach request message to MTC terminal, when adopting implicit, SGSN/MME can not send detach request message to MTC terminal, but directly triggers attachment removal flow process, in the present embodiment, the previous case of take is introduced as example, all like this in subsequent embodiment, will repeat no more.
Step 510: after receiving detach request message, MTC terminal returns to adhere to SGSN/MME and accepts message and respond.
Step 520:SGSN/MME sends state update request message to HLR/HSS, to HLR/HSS, notifies the attachment state of MTC terminal to change.
In state update request message, at least need to carry the attachment removal type information of MTC terminal, be used to indicate the network type of the attachment removal of MTC terminal, for example, in state update request message, can comprise: the identification information of MTC terminal (as, IMSI, MSISDN(Subscriber ISDN Number, mobile subscriber ISDN number) etc.), the attachment removal type information of MTC terminal etc.The in the situation that of inactive I SR mechanism, if being SGSN in GPRS network, the state update request message recording in this step sends, the attachment removal type of MTC terminal is: the network attachment removal of GPRS PS territory; If the state update request message recording in this step is the MME in EPS network, initiate, the attachment removal type of MTC terminal is: the attachment removal of EPS network.
Step 530:HLR/HSS is according to the attachment removal type information of the MTC terminal of carrying in state update request message, and the reachable state information that corresponding MTC terminal is preserved is carried out corresponding renewal, and upgrades response message to SGSN/MME return state.
Be specially: SGSN/MME is carried at attachment removal type information in state update request message and is sent to HLR/HSS, HLR/HSS, in the reachable state information of the contextual information record of MTC terminal, is designated as " attachment removal " by the attachment state of MTC terminal attachment removal network; Afterwards, HLR/HSS will upgrade the successful renewal that response message is confirmed the reachable state information of MTC terminal to SGSN/MME return state.
Further, in the information as shown in table 2 that corresponding MTC terminal is preserved, having recorded MTC terminal is attachment removal state at GPRS PS territory network or EPS network, and when CS territory network is attachment removal state, HLR/HSS will be designated as " attachment removal " the attachment state of MTC terminal as shown in table 1.

When step 600:SGSN/MME confirms that network side no longer provides related service for MTC terminal, to MTC terminal, send detach request message.
In practical application, according to the regulation of related protocol, SGSN/MME can adopt explicit way or implicit by the attachment removal of MTC terminal, when adopting explicit way, SGSN/MME can send detach request message to MTC terminal, when adopting implicit, SGSN/MME can not send detach request message to MTC terminal, but directly triggers attachment removal flow process, in the present embodiment, the previous case of take is introduced as example, all like this in subsequent embodiment, will repeat no more.
Step 610:SGSN/MME judges whether ISR mechanism activates, and another MME/SGSN if so, simultaneously registering to MTC terminal sends attachment removal notification message; Otherwise, according to step 520-step 530, carry out relevant treatment; In the present embodiment, take and activate ISR mechanism and carry out related description as example.
When another MME/SGSN simultaneously registering to MTC terminal as SGSN/MME sends attachment removal notification message, can notify the other side's attachment removal former because " Complete ", or, be " Local ".
Step 620:MME/SGSN carries out attachment removal relevant treatment according to existing protocol, and returns to and adhere to acknowledge message and respond to SGSN/MME.
Step 630: in the situation that receiving detach request message, MTC terminal returns to adhere to SGSN/MME and accepts message and respond.
Step 640:SGSN/MME sends state update request message to HLR/HSS, to HLR/HSS, notifies the attachment state of MTC terminal to change.
In state update request message, at least need to carry the attachment removal type information of MTC terminal, be used to indicate the network type of the attachment removal of MTC terminal, for example, in state update request message, can comprise: the identification information of MTC terminal (as, IMSI, MSISDN etc.), attachment removal type information of MTC terminal etc.If the state update request message recording in this step is the SGSN in GPRS network, send, the attachment removal type of MTC terminal is: the network attachment removal of GPRS PS territory; If the state update request message recording in this step is the MME in EPS network, initiate, the attachment removal type of MTC terminal is: the attachment removal of EPS network.
Step 650:HLR/HSS is according to the attachment removal type information of the MTC terminal of carrying in state update request message, and the reachable state information that corresponding MTC terminal is preserved is carried out corresponding renewal, and upgrades response message to SGSN/MME return state.
