Below, describe each embodiment of the present invention in detail in connection with accompanying drawing.It will be appreciated by those skilled in the art that following each embodiment purpose that occurs only is used for describing various aspects of the present invention in detail, rather than be used for limiting protection scope of the present invention.
Referring to Fig. 1, it shows the method flow diagram that is used for determining information transmission mode according to one embodiment of the invention.
In step 110, the MTC terminal sends to MME with the network location information of its network area, current place when occurrence positions changes, and this positional information can be the identification information of network.For example, this network area can be the public land mobile network (PLMN shown in figure, Public Land Mobile Network), when the MTC terminal is attached to a PLMN or position and is updated to a PLMN or switches to a PLMN, represent that all change in location has occured this MTC terminal.Particularly, in step 110, the MTC terminal can be in network attachment process or position updating process or handoff procedure, and sign (ID, the Identification) information (being PLMN ID) of the PLMN at its current place is sent to MME.
In this step, the MTC terminal can also send to MME with its identification information, this identification information can comprise various ways, international mobile subscriber identity (IMSI for example, International Mobile Subscriber Identification Number), travelling carriage comprehensive service digital net number (MSISDN, Mobile Station ISDN (Integrated Services Digital Network) Number), MME distribute to user's temporary mark of MTC terminal, user's external business layer sign etc.Here the terminal identification information that sends can be one or more combinations of above-mentioned user ID.
In step 120, MME sends to the network location information of the network area, the current place of MTC terminal of receiving to HSS, in the embodiment shown in fig. 1, MME sends to HSS with the PLMN ID of the current place PLMN of MTC terminal, so that upgrade the PLMN ID of the current place PLMN of this MTC terminal for this MTC terminal in HSS.For example, when the MTC terminal location changed, MME sent position updating request to HSS, above-mentioned PLMN ID can be placed on and send to HSS in position updating request.Thereby, preserve the current location information of the terminal that belongs to this PLMN in HSS, being that terminal is current is served in which PLMN, and this current location information can be identified by the PLMN ID of the current place PLMN of terminal, alternatively also can be by the PLMN name identification.
In this step, MME can also send to HSS with the identification information of MTC terminal, and it can be one or more combinations of above-mentioned user ID that MME sends to the terminal identification information of HSS; It can be the direct forwarding of the user ID received of step 110; Can be also through the sign after the MME conversion, for example, MME had received the user ID IMSI of MTC terminal and had given the MTC terminal distribution user's temporary mark before step 110, what MME received in step 110 is user's temporary mark of MTC, and MME can be converted to IMSI with this user's temporary mark and send to HSS.
In step 130, the MTC application server will trigger the initiation of MTC terminal to the communication connection of MTC application server, and the MTC application server can send triggering request to MTC service interaction function (IWF, InterWorking Function) entity.This triggering request comprises the identification information of target MTC terminal, with request MTC IWF entity, this triggering request is sent to this target MTC terminal.
In step 140, MTC IWF entity uses the target MTC terminal identification information of receiving from the MTC application server to inquire about HSS.Particularly, MTC IWF entity sends query requests to HSS, and this query requests comprises the identification information of target MTC terminal, and HSS comes the PLMN at the current place of query aim MTC terminal according to the identification information of target MTC terminal with request.
In step 150, HSS is by determining the PLMN at the current place of target MTC terminal according to the identification information inquiry local data base of target MTC terminal, and it can be identified by PLMN ID, alternatively also can be by the PLMN name identification.In this step, HSS sends inquiry response to MTC IWF entity, and this inquiry response comprises the PLMN ID of the current place PLMN of target MTC terminal.As previously mentioned, this PLMN ID also can be substituted by the PLMN title.
in step 160, MTC IWF entity is according to the PLMN ID of the current place PLMN of target MTC terminal, by inquiring about local PLMN information transmission mode tenability separately of preserving (namely, the information transmission mode that each PLMN supports) can determine the information transmission mode that the current place PLMN of target MTC terminal supports, and then the information transmission mode that place PLMN current according to target MTC terminal supports is determined a kind of for transmit the information transmission mode of triggering request to target MTC terminal, namely select a kind of for transmit the information transmission mode of triggering request to target MTC terminal in the information transmission mode that the current place PLMN of target MTC terminal supports.
The below illustrates application scenarios of the present invention.Suppose that MTC IWF entity is arranged in PLMN1, according to the network design of operator and roaming agreement etc., in MTC IWF physical arrangements the information transmission mode tenability of PLMN1, PLMN2, PLMN3.It should be appreciated by those skilled in the art that the information transmission mode tenability of just having supposed to configure PLMN1, PLMN2, PLMN3 here for the convenience that illustrates, and can configure the information of the PLMN of arbitrary number in specific implementation.In this example, PLMN1 only supports traditional note transmission means, namely only supports to have the user's that circuit domain signing (that is, having MSISDN) is arranged note transmission; PLMN2 supports the note transmission of upgrading, and namely no matter whether the user has MSISDN, can carry out the note transmission to this user; PLMN3 only supports MTC IWF entity directly to send to MME, then sends the transmission method of terminal to by chain of command message by MME.In this example, a MTC terminal attaching is in PLMN1, but roams at present the PLMN3 network, and the roaming network PLMN3 at MTC terminal present place has been upgraded by MME by above-mentioned steps 110 and 120 and has been saved in HSS.
The embodiment that describes in conjunction with Fig. 1 above utilizing, when the MTC application server need to trigger a target MTC terminal that belongs to PLMN1 and initiates communication connection to the MTC application server, the MTC application server sends triggering request to MTC IWF entity, and this triggering request comprises the user totem information of target MTC terminal.After MTC IWF entity is received this triggering request, use the identification information of target MTC terminal to the current residing PLMN of HSS query aim MTC terminal, and obtain the identification information of the PLMN3 that inquires from HSS.MTC IWF entity can be according to the message transmission capability of each PLMN that preserves in the PLMN3 identification information of receiving and MTC IWF entity, determine the information transmission mode that PLMN3 supports, and determine for target MTC terminal the information transmission mode that PLMN3 supports accordingly, namely MTC IWF entity is directly issued MME with trigger request information and is sent to the information transmission mode of target MTC terminal by MME by chain of command message again.
In this embodiment, pre-configured PLMN information transmission mode tenability separately in MTC IWF entity, for example, can be when on-premise network or during network upgrade, pre-configured PLMN with this MTC IWF entity place has the information transmission mode tenability of the PLMN of roaming agreement in MTC IWF entity.
The information transmission mode that PLMN can support can comprise one or more, for example, traditional circuit domain note transmission means and/or inverter circuit territory contracted user's note is transmitted and/or is directly sent to MME to send MTC terminal and/or other transmission meanss by MME to by chain of command message again by MTC IWF entity.In this embodiment, by determining that the information transmission mode that the current place PLMN of a kind of target MTC terminal supports to send triggering request to target MTC terminal, overcome the current place PLMN of target MTC terminal might not support the information transmission mode that adopts potential may, can more reliably triggering request be sent to target MTC terminal.
Need to prove, the PLMN information that obtains from the HSS inquiry may not be unique decisive factor that MTC IWF entity is determined information transferring method, for example when the current place PLMN of target MTC terminal supports multiple transmission means, MTC IWF entity can also be determined best transmission means according to other factors (for example will transmit the data package size of message), but mainly described in embodiments of the invention and the maximally related definite factor of basic principle of the present invention, namely determined the information transmission mode that the current place PLMN of a kind of target MTC terminal supports.Support the situation of much information transmission means for the current place PLMN of target MTC terminal, can further adopt any other factor to determine the information transmission mode that a kind of this PLMN supports, all can overcome above-mentioned technical problem.For example, when configuring the information transmission mode tenability of each PLMN in MTC IWF entity, for each PLMN, the information transmission mode that this PLMN can be supported distributes different priorities, in the situation that do not consider other factors, can determine that the highest transmission means of priority transmits message.Perhaps, when configuring the information transmission mode tenability of each PLMN in the MTCIWF entity, for each PLMN, wherein a kind of information transmission mode that this PLMN supports can be appointed as the acquiescence mode, in the situation that do not consider other factors, can determine that this default transport mode transmits message.
When being applicable to operator's on-premise network, adopts embodiment shown in Figure 1 the situation of the whole network upgrading mode, namely a PLMN supports identical information transmission mode in its network range, in other words, the network entity in PLMN has identical transmission means tenability.For example, a PLMN only supports traditional circuit domain note transmission means, after the transmission of the note in this PLMN that upgraded network element, makes this PLMN both support traditional circuit domain note transmission means, also supports inverter circuit territory contracted user's note transmission.Again for example, a PLMN also can only support directly to send to MME by MTC IWF entity, then sends the method for terminal to by chain of command message by MME.Again for example, PLMN can support above various transmission means or other to be not limited to transmission means described above.In the present embodiment, no matter the user is in any geographical position of this PLMN, and the transmission means of network support can not change, namely, the tenability of data information transfer mode be the PLMN level other.
Although it will be understood by those skilled in the art that the tenability of data information transfer mode in embodiment shown in Figure 1 be the PLMN level other, the described method of this embodiment also can be applied to other the level other data information transfer mode tenability.For example, a PLMN can be divided into a plurality of network areas that a plurality of MME serve respectively, in this PLMN, the information transmission mode that each MME supports can be identical can be also different.In the embodiment that replaces, can configure the information transmission mode tenability of each MME in each PLMN in the MTCIWF entity, when the terminal occurrence positions changes, MME can send location update message to upgrade the identification information of the MME that is currently serviced in this terminal for this terminal in HSS to HSS, and MTC IWF entity can be currently serviced in to the HSS inquiry MME of target terminal, and then determine the information transmission mode that this MME supports, and determine that therefrom a kind of information transmission mode comes to send message to target terminal.In this alternative embodiment, the tenability of data information transfer mode be the MME level other, adopt the situation of the whole network upgrading mode when namely being applicable to operator's on-premise network, adopt the situation of part network element updating mode when also being applicable to operator's on-premise network.
In the variant embodiment of embodiment shown in Figure 1, can further consider the information transmission mode tenability of terminal.MTC IWC entity can be further be identified for sending to this terminal the information transmission mode of triggering request according to the information transmission mode tenability of the information transmission mode tenability of the network area at terminal current place and terminal.For example, preferably, determine that the information transmission mode that a kind of terminal network area, current place and terminal are all supported to send message to terminal.
In this variant embodiment, in step 150 embodiment illustrated in fig. 1, by the information transmission mode tenability of HSS to MTC IWF entity transmitting terminal.For example, the information transmission mode tenability of terminal can be that this locality is configured in HSS, can be also that UE is reported to MME to be reported to HSS by MME again in network attachment process or position update flow, for example in step 110 shown in Figure 1 and 120 with PLMN ID simultaneously or be reported to respectively MME and HSS.
Referring to Fig. 2, it shows the method flow diagram that is used for determining information transmission mode according to another embodiment of the present invention.
In step 230, MTC IWF entity can be signing to HSS, with the signing user terminal of configuration in HSS.When HSS changes in the network area at contracting terminal place initiatively with the update of identification information of network area, the current place of this contracting terminal to MTC IWF, to upgrade the identification information of its network area, current place for this contracting terminal in MTC IWF.
This step 230 is optional steps, and for example, HSS also can be according to the configuration of self, and need not signing to HSS of MT reconnaissance C IWF, when the PLMN at the terminal place changes initiatively with the information updating of the current place PLMN of terminal to MTC IWF entity.
In step 240, when HSS changes in the network area at terminal place initiatively with the update of identification information of network area, the current place of terminal to MTC IWF, to upgrade the identification information of its network area, current place for this terminal in MTC IWF.For example, when the PLMN at terminal current place changes, HSS can send location update message to MTC IWF entity, this location update message comprises the positional information (for example PLMN ID) of the current place PLMN of terminal, to upgrade the positional information of its current place PLMN for this terminal in MTC IWF this locality.
In step 260, MTC IWF is after receiving the trigger request that comprises the target terminal identification information that the MTC application server sends, can determine the network area at the current place of target terminal in the positional information of the network area, the current place of terminal of the local real-time update of MTC IWF according to the identification information of target terminal, and then the information transmission mode supported of the network area at definite target terminal current place, and determine that therefrom a kind of information transmission mode is to be used for sending triggering request to target terminal.For example, MTC IWF entity is determined the PLMN ID of the current place PLMN of target terminal in this locality according to the user totem information of target terminal, by according to the information transmission mode tenability of local each PLMN that preserves of this PLMN ID inquiry (namely, the information transmission mode that each PLMN supports) can determine the information transmission mode that the current place PLMN of target terminal supports, and then determine a kind of for transmit the information transmission mode of triggering request to target terminal in the information transmission mode that the current place PLMN of target terminal supports.
Although it will be understood by those skilled in the art that the tenability of data information transfer mode in embodiment shown in Figure 2 be the PLMN level other, the described method of this embodiment also can be applied to other the level other data information transfer mode tenability.For example, PLMN can be divided into a plurality of network areas that a plurality of MME cover, in this PLMN, the information transmission mode that each MME supports can be identical can be also different.in the embodiment that replaces, can configure the information transmission mode tenability of each MME in each PLMN in MTC IWF entity, when the terminal occurrence positions changes, MME can send location update message and HSS to HSS can send updating message to upgrade the identification information of the MME that is currently serviced in this terminal for this terminal in MTC IWF entity to MTC IWF entity, thereby MTC IWF entity can determine to be currently serviced in this locality the MME of target terminal, and then the information transmission mode of definite this MME support, and determine that therefrom a kind of information transmission mode comes to send message to target terminal.In this alternative embodiment, the tenability of data information transfer mode be the MME level other, adopt the situation of the whole network upgrading mode when namely being applicable to operator's on-premise network, adopt the situation of part network element updating mode when also being applicable to operator's on-premise network.
Identical with above-mentioned variant embodiment embodiment illustrated in fig. 1, in the variant embodiment of embodiment shown in Figure 2, also can further consider the information transmission mode tenability of terminal.The MTCIWC entity can be further be identified for sending to this terminal the information transmission mode of triggering request according to the information transmission mode tenability of the information transmission mode tenability of the network area at terminal current place and terminal.For example, preferably, determine that the information transmission mode that a kind of terminal network area, current place and terminal are all supported to send message to terminal.In this variant embodiment, in step 240 embodiment illustrated in fig. 2, by the information transmission mode tenability of HSS to MTC IWF entity transmitting terminal.For example, the information transmission mode tenability of terminal can be that this locality is configured in HSS, can be also that UE is reported to MME to be reported to HSS by MME again in network attachment process or position update flow, for example in step 210 shown in Figure 2 and 220 with PLMN ID simultaneously or be reported to respectively MME and HSS.
Referring to Fig. 3, it shows the method flow diagram that is used for determining information transmission mode according to another embodiment of the present invention.
In step 310, the MTC terminal is when occurrence positions changes, and it is to a new MME registration.For example, a PLMN or position are updated to a PLMN or when switching to a PLMN or being updated to the network area of another MME service from the position, network area of a MME service, represent that all change in location has occured this MTC terminal when the MTC terminal is attached to.Particularly, in step 310, the MTC terminal can be in network attachment process or position updating process or handoff procedure, to a new MME registration.In this step, the MTC terminal can also send to MME with its identification information.
