Embodiment

For making the object of the invention, technical scheme and advantage clearer, the embodiment of the invention is done further explain below in conjunction with accompanying drawing.At this, illustrative examples of the present invention and explanation thereof are used to explain the present invention, but not as to qualification of the present invention.

According to IMSI standard criterion ITU-E.212; The IMSI total length can not be above 15; And form by three parts, be respectively Mobile Country Code MCC (MCC, Mobile Country Code), mobile network number (MNC; Mobile Network Code), mobile identification number (MSIN, Mobile Subscriber Identification Number).MNC and MSIN form domestic mobile user identification (NMSI, National Mobile Subscriber Identification).

Fig. 1 is the structural representation of IMSI.As shown in Figure 1, the country under the Mobile Country Code MCC MCC sign mobile subscriber is made up of three bit digital.For example, the MCC of China is 460.

The mobile network number MNC sign mobile network that the mobile subscriber belonged to, i.e. public land mobile communication network (PLMN, PublicLand Mobile-communication Network).Be made up of two or three bit digital, length depends on the value of MCC.For example, it is 00 that the time division multiple access of China Mobile inserts (TDMA, Time Division Multiple Access) digital public cellular mobile communications networks, and the public cellular mobile communications networks of TDMA numeral of CHINAUNICOM is 01.

A mobile subscriber in the mobile identification number MSIN sign PLMN is made up of 10 bit digital.For the ease of describing, below the description of MSIN is represented with H0H1H2H3ABCDEF.

As shown in Figure 1, IMSI is made up of 15 ten's digits altogether, can hold 100,000,000,000,000 users when using fully, is far smaller than this numeral but remove redundant back actual capacity.For example, for China, country code accounts for 3, and overall system capacity is 100,000,000,000, and mobile network No. accounts for 2 again, and for some PLMN, the number of users that can hold is merely 1,000,000,000.Table 1 is seen in capacity analysis.

Table 1-1

Sign	The scope of application	Total capacity	Country's capacity	The PLMN capacity
					IMSI	The whole world is unique	100,000,000,000,000	Hundred billion	1,000,000,000

From the above, current I MSI adopts ten's digit to represent.But IMSI is aloft on the interface and when on core network interface, transmitting, and all adopts 4bit to represent each of IMSI, and 4bit can represent 16 different numerals.Can know that by TS24.008V9.1.0 for IMSI each (4bit), current I MSI has only used from 0 to 9 ten's digit, use 4 complete 1 (the being hexadecimal F) expression of bit fillers in addition.Therefore, all the other 5 (being hexadecimal A to E) are not used.

Thus, the present invention proposes the IMSI capacity is expanded, in an embodiment of the present invention, follow the length of IMSI and can not surpass 15 requirement, adopt hexadecimal to replace the decimal system to represent IMSI.Like this, both can distinguish MTC contracted user and H2H contracted user, can reach the purpose that the IMSI capacity is expanded again.Below be elaborated through specific embodiment.

Embodiment 1

The embodiment of the invention provides a kind of machine class communication contracted user's recognition methods, and as shown in Figure 2, this method comprises:

Step 201 is obtained contracted user's IMSI;

Step 202 is judged the hexadecimal notation that whether has any or its combination of A to E among the IMSI;

Step 203 is if judged result, confirms then that this contracted user is the MTC contracted user for existing.

According to the hexadecimal notation that has any or its combination of A to E among the IMSI, only be to confirm the necessary condition of contracted user in the step 202 that those of ordinary skills it should be understood that for the MTC contracted user.But be not limited thereto, any other conditions that on the basis of this condition, combine confirm that the contracted user is MTC contracted user's a technical scheme, all should be included within protection scope of the present invention.

When step 202 is implemented, can distinguish MTC contracted user and H2H contracted user in the MCC of IMSI section.Particularly: whether the MCC that judges IMSI exists the hexadecimal notation of any or its combination of A to E; If judged result is the hexadecimal notation that has any or its combination of A to E, then this contracted user is the MTC contracted user; Otherwise this contracted user is the H2H contracted user.

In the present embodiment, MCC accounts for three (each is made up of 4 bit) among the IMSI, adopts hexadecimal notation to represent.The theoretical capacity of MCC can by 1000 be increased to 3375 (each from 0 to 14 be hexadecimal value from 0 to E; 4 bit complete 1 of each are that hexadecimal value F is as filler); The MCC that wherein is made up of numeral fully is 1000, and the MCC that comprises any or its composite symbol from A to E is 2375, and there are 225 countries and regions in the whole world; The MCC that is made up of numeral is fully kept the use to the H2H contracted user, give MTC contracted user use and will comprise alphabetical MCC.Like this, distribute a MCC just to allow 100,000,000,000,000 MTC contracted users for a country and exist, if can apply for extra MCC to ITU-T inadequately, on average each country just has more than ten MCC.

Particularly,, given each national MCC, and the MCC that will be made up of numeral fully keeps for the H2H contracted user use of communicating by letter still by this national H2H contracted user use of communicating by letter in order to be consistent with existing network; Distribute a MCC who comprises the hexadecimal notation of any or its combination from A to E (also to be for each country; In the hex bit that MCC shared three is made up of 4bit; The value of any hex bit is that A is to one of E); Supply MTC contracted user uses of communicating by letter, when an employed IMSI resource of national MTC contracted user will be exhausted, can be to extra MCC confession MTC contracted user who comprises letter of ITU-T TSB application use of communicating by letter.

In addition, owing in the MCC section H2H contracted user and MTC contracted user are distinguished, MNC only need be used for distinguishing PLMN and get final product.IMSI for the H2H contracted user communicates by letter and uses can distribute to each operator with MNC according to existing scheme fully; And the IMSI that communicates by letter and use for the MTC contracted user, country can formulate new standard criterion MNC is distributed to each operator.And MSIN (for example, the H0H1H2H3ABCDEF) terminal use of sign in the PLMN.

When step 202 is implemented, can also distinguish MTC contracted user and H2H contracted user in the MNC of IMSI section.Particularly: whether the MNC that judges IMSI exists the hexadecimal notation of any or its combination of A to E; If judged result is the hexadecimal notation that has any or its combination of A to E, then this contracted user is the MTC contracted user; Otherwise this contracted user is the H2H contracted user.

In the present embodiment, MNC accounts for two or three among the IMSI.China accounts for two, adopts hexadecimal notation to represent, theoretical capacity can be increased to 225 from 100, and the MNC that wherein is made up of numeral fully is 100, and the MNC that comprises from A to E is 125.If when distributing MCC, H2H contracted user and MTC contracted user are not distinguished, then can distinguish H2H contracted user and MTC contracted user in the MNC section.

Concrete; It is consistent with existing network that MCC keeps; Given each national national code MCC and still used by this country, the shared MCC of the H2H contracted user of same country and MTC contracted user does not distinguish H2H contracted user and MTC contracted user in the MCC section; Even country has applied for comprising the MCC of letter again to ITU-T in the future, this MCC still can be shared by H2H contracted user and MTC contracted user.

Because the MCC section is not distinguished H2H contracted user and MTC contracted user; Need distinguish it in the MNC section; Can 100 MNC that be made up of numeral fully be distributed to the H2H contracted user and use, distribute to MTC contracted user use and will contain 125 alphabetical MNC.For example, with 00 give certain standard of certain operator the H2H contracted user, 0A is distributed to the MTC contracted user etc. of certain standard of certain operator.And MSIN (for example, the H0H1H2H3ABCDEF) terminal use of sign in the PLMN.

Thus, this method is well suited for those populations, country that equipment is few, because as long as a MCC is just much of that, distributing two MCC is the wastes to resource.In the less country of the size of population, only need to reserve enough MNC and supply H2H contracted user use to get final product, will all not keep for the H2H contracted user by whole 100 MNC, the remaining MTC contracted user that can all keep for uses.

When step 202 is implemented, can also be all digit separator MTC contracted users and the H2H contracted user of IMSI.Particularly: whether all that judge IMSI exist the hexadecimal notation of any or its combination of A to E; If judged result is the hexadecimal notation that has any or its combination of A to E, then this contracted user is the MTC contracted user; Otherwise this contracted user is the H2H contracted user.

In the present embodiment, because current I MSI only uses numeral, in order to keep maximum compatible with existing network, can the IMSI that use numeral fully be distributed to the H2H contracted user and use, the IMSI that will include one of hexadecimal value A-E distributes to the MTC contracted user.

Particularly; The MCC that is made up of numeral that has given each country is still used by this country; The shared MCC of the H2H contracted user of same country and MTC contracted user; When the IMSI of country number resource is exhausted, can apply for an extra MCC to ITU-T, the MCC that includes letter (being the value of non-0-9 in the hexadecimal value) can only be used by the MTC contracted user.The MNC that is made up of numeral that has distributed to each PLMN is still used by this PLMN, and the MNC that includes letter can only distribute to the MTC contracted user use of communicating by letter.The MSIN that is made up of numeral fully can only be used by the H2H contracted user, and the MSIN that includes letter is used by the MTC contracted user.

In the present embodiment, after definite contracted user was the MTC contracted user, can also in MTC contracted user's mobile management (MM, Mobile Management) context, write down this contracted user was the MTC contracted user, for example, can increase the MTC sign.

In addition, can also be when network congestion, according to MTC sign in the MM Context, or to the judgement of IMSI, the service that refusal or postpone provides the MTC contracted user.Judgement to IMSI can be repeated no more as stated here.

Through the foregoing description, can expand the capacity of IMSI, expand the theoretical capacity of back IMSI and see table 2:

Table 2

Sign	The scope of application	Total capacity	Country's capacity	The PLMN capacity
					IMSI	The whole world is unique	4,000,000,000	100,000,000,000,000	500,000,000,000

Contrast table 1 can be known with table 2; The total capacity of expansion back IMSI is increased to 4,000,000,000 by original 100,000,000,000,000; Each national capacity is increased to 100,000,000,000,000 by original hundred billion; The capacity of each PLMN is increased to 500,000,000,000 by original 1,000,000,000, has greatly improved the capacity of IMSI, makes IMSI after the expansion can satisfy the sign demand at the TERA-SCALE quantity terminal that following MTC introduces.

Can know by the foregoing description, replace the decimal system to represent IMSI through adopting hexadecimal; Both can distinguish MTC contracted user and H2H contracted user, and can make the capacity of IMSI satisfy growing terminal use's demand again.

Embodiment 2

The embodiment of the invention provides a kind of MTC contracted user's recognition methods on the basis of embodiment 1, be applied in the EPS system.Below attaching process through the EPS system carry out detailed explanation.

Fig. 3 is the flow chart of the attaching process of EPS system, and is as shown in Figure 3, and this method comprises:

Step 301, mobile management entity (MME, Mobile Management Entity) obtains contracted user's ISMI.

In the present embodiment, as shown in Figure 3, step 301 can further comprise:

Step 301.1; Contracted user's subscriber equipment (UE; User Equipment) sends Attach Request message (Attach Request) to eNodeB, if the contracted user has available old global unique temporary identity symbol (GUTI, GlobalUnique Temporary UE Identity); Then carry old GUTI in this Attach Request message, identify the contracted user otherwise carry IMSI.

Step 301.2, eNodeB selects new MME by Radio Resource control (RRC, Radio Resource Control) protocol parameter, and adheres to message (Attach Request) to new MME forwarding.

Alternatively; Step 301.3; If the contracted user is with GUTI sign oneself, and MME changes after separating last time, then new MME obtains old MME by GUTI; And, carry GUTI and complete Attach Request message in this ID authentication request message to old MME transmission ID authentication request message (IdentificationRequest).

Alternatively, step 301.4, old MME sends authentication response message (IdentificationResponse) to new MME, and this authentication response message includes IMSI, MM (Mobile Management, mobile management) context.

Alternatively, step 301.5 if the contracted user can not know that at old MME then new MME sends identification request (Identity Request) to this UE, is asked this contracted user's IMSI.

Alternatively, step 301.6, this UE sends response message (Identity Response) to new MME, and this message comprises this contracted user's IMSI.

So far, new MME has obtained this contracted user's IMSI from UE, has perhaps obtained contracted user's IMSI from local or old MME through GUTI.

Step 302 when new MME comprises the hexadecimal notation of A to E any or its combination in IMSI, confirms that this contracted user is the MTC contracted user.

Particularly, step 302 can comprise:

Whether the MCC that judges IMSI exists the hexadecimal notation (promptly judging in the MCC of IMSI with every 4bit to be that the hexadecimal value whom whether has is one of A-E among everybody of one) of any or its combination of A to E; If judged result is the hexadecimal notation that has any or its combination of A to E, then this contracted user is the MTC contracted user; Otherwise this contracted user is the H2H contracted user;

Perhaps, whether the MNC that judges IMSI exists the hexadecimal notation (promptly judging in the MNC of IMSI with every 4bit to be that the hexadecimal value whom whether has is one of A-E among everybody of one) of any or its combination of A to E; If judged result is the hexadecimal notation that has any or its combination of A to E, then this contracted user is the MTC contracted user; Otherwise this contracted user is the H2H contracted user.

Perhaps, whether all that judge IMSI exist the hexadecimal notation (promptly judging in IMSI with every 4bit to be that the hexadecimal value whom whether has is one of A-E in all positions of one) of any or its combination of A to E; If judged result is the hexadecimal notation that has any or its combination of A to E, then this contracted user is the MTC contracted user; Otherwise this contracted user is the H2H contracted user.

Step 303, if this contracted user is the MTC contracted user, then this contracted user of record is the MTC contracted user in MTC contracted user's MM context, for example increases the MTC sign.

Thus, in the EPS system, when the contracted user was attached to some MME for the first time or routes to a new MME, new MME can be from UE, or obtain contracted user's IMSI through contracted user's GUTI; Then, new MME can identify through the judgement to IMSI whether the contracted user who is asked is the MTC contracted user, and when making up the MM context for this contracted user, writes down this characteristic.

In the present embodiment; If current network is in congestion state, MME can refuse adhering to and tracking area update of this MTC contracted user judging the contracted user through IMSI for behind the MTC contracted user; And with going up suitable cause value; MME also just no longer for the MTC contracted user sets up default bearer, avoids the emphasis network congestion condition, thereby protection H2H contracted user communication can normally be carried out.

Alternatively, as shown in Figure 3, this method also can comprise step 304, initiates authentication process (Authentication/Security) when needed.

Further, in the present embodiment, change if separated (being that UE is connected with the MME disconnection) back MME from last time, then MME also can search user contracting data for behind the MTC contracted user definite contracted user, specifically can be of step 305 to step 309.

Step 305, new MME sends to home subscriber server (HSS, Home Subscriber Server) and upgrades position requests (Update Location); Wherein, this request comprises IMSI, also comprises the MME sign.

Step 306, HSS confirms according to IMSI whether this contracted user is the MTC contracted user; After confirming as the MTC contracted user, search user contracting data in MTC contracted user's subscription data district.

In the present embodiment, confirm that according to IMSI whether the user is that the MTC contracted user specifically can adopt aforesaid method, repeats no more here.

Alternatively, step 307, HSS sends cancel location message (Cancel Location) to old MME, carries IMSI, cancellation type in this cancel location message.

Alternatively, step 308, old this contracted user's of MME deletion MM context sends response message (CancelLocation ACK) to HSS, carries IMSI in this response message.

Alternatively, step 309, HSS responds to new MME and upgrades position acknowledge message (Update Location ACK), and this acknowledge message is carried IMSI and user contracting data;

Comprise one or more packet data network (PDN in the user contracting data; Packet Data Network) signatory context; The signatory context of each PDN comprises an EPS subscribed services quality (Qos, Quality of Service) attribute and signatory APN-AMBR (Access Point Name-Aggregate Maximum Bit Rate).

If the subscription data restriction contracted user adhere to or other signature data verification failures at this tracking area (TA, Tracking Area), new MME refusal contracted user reason on this TA adheres to and is with.If checking is all passed through, new MME is the textural hereinafter of contracted user.

Further; Step 310, when setting up session for the contracted user, new MME can be according to the record of this contracted user in the MM context for machine class communication contracted user; For the contracted user selects suitable grouped data network gateway (P-GW, PacketData Network GateWay);

In the present embodiment, MME can be according to the access point (APN, Access Point Name) that the MTC in the MM context indicates and user contracting data provides, for the MTC contracted user selects suitable P-GW.For example, disposed different P-GW with the MTC contracted user, the P-GW that MME should select to supply the MTC contracted user to communicate by letter and use for the MTC contracted user, the competitive resource of avoiding communicating by letter with the H2H contracted user if be respectively the H2H contracted user.

In the present embodiment, new MME also can send to this P-GW with the MTC sign through conversation request message, and this P-GW is stored in the MTC sign in contracted user's the EPS bearer context.

Further, when network congestion, this P-GW can according to this MTC sign refusal or the session that postpones this contracted user set up request, or reduce this contracted user service quality guarantee, or discharge the data that this contracted user set up and connect.

Particularly, in the present embodiment, also can set up the up/down user data tunnel of eNodeB to S-GW, can be like step 311 to 322 said.

Alternatively; Step 311; New MME sends to gateway (S-GW, Serving GateWay) and creates conversation request (Create Session Request), and uses the P-GW that selects as the MTC contracted user in the step 310 to activate default bearer as the MTC contracted user.

In the present embodiment; New MME is that the default bearer at this terminal distributes an EPS Bearer ID; Select a S-GW and send the establishment conversation request to it; Carry IMSI, MTC sign, MSISDN (MobileSubscriber International ISDN/PSTN Number), MME chain of command TEID (Tunnel EndpointIdentifier), P-GW address, PDN address, APN, PDN type, EPS Bearer ID and mobile terminal identification (MEID, Mobile Equipment Identifier) in this establishment conversation request.

Alternatively, step 312, S-GW sets up a list item in the EPS carrying table of oneself, and the indicated P-GW in the P-GW address that in step 311, is obtained sends establishment conversation request message (Create Session Request).

In the present embodiment, can comprise IMSI, MTC sign, MSISDN, APN, S-GW user plane address, S-GW user plane TEID, S-GW chain of command TEID, PDN address, PDN type, EPS Bearer ID and ME ID etc. in this establishment conversation request message.

Alternatively, step 313, P-GW returns to S-GW and creates conversation request response message (Create SessionResponse).Can comprise P-GW user plane address, P-GW user plane TEID in this response message, P-GW chain of command TEID, PDN address, PDN type, EPS Bearer ID and charge ID etc.

In the present embodiment, P-GW sets up a new list item after receiving and creating conversation request in the EPS carrying table of oneself, and for it generates a charge ID, this list item makes P-GW can make user data route between S-GW and PDN, and begins to charge.

In the present embodiment; P-GW also will with the strategy with charging regulation function entity (PCRF; Policy and ChargingRules Function) links up; The QoS that the contracted user is asked for default bearer holds consultation, if current network conditions is congested, P-GW will according to MTC sign refusal or the session that postpones the MTC contracted user set up request or reduce the MTC contracted user the QoS index, or discharge the data that the MTC contracted user set up and connect.

Alternatively; Step 314; S-GW returns to new MME and creates conversational response message (Create Session Response), can comprise PDN type, PDN address, S-GW user plane address, S-GW user plane TEID, S-GW chain of command TEID, EPS Bearer ID, P-GW address and some TEID etc. in this response message.

Alternatively, step 315, new MME sends to adhere to eNodeB and accepts message (Attach Accept).This adheres to accepts can to comprise in the message in APN, GUTI (giving the newly assigned GUTI of contracted user), PDN type, PDN address, TAI tabulation, EPS Bearer ID, session management request and the step 314 user plane IP address and the user plane TEID etc. that passed to the S-GW of MME by S-GW.

So far, set up to the uplink user data tunnel of S-GW by eNodeB.

Alternatively; Step 316; ENodeB sends RRC to UE and connects reconfiguration message (RRC ConnectionReconfiguration), can comprise EPS RB-ID in this message, adhere to message and the APN information etc. accepted, and APN information is used for the pairing APN of default bearer that tells the user to activate.

Alternatively, step 317, parameters such as the Qos that the UE storage is consulted, Radio priority level are sent RRC to eNodeB and are reshuffled completion message (RRC Connection Reconfiguration Complete).

Alternatively, step 318, eNodeB sends initial context response message (Initial Context SetupResponse) to new MME.The IP address and the TEID that can comprise eNodeB in this message, this TEID are used to supply eNodeB to receive the down link data from S-GW.

Alternatively, step 319, UE sends direct-sending message (Direct Transfer) to eNodeB, comprises and adheres to completion message, and this adheres in the completion message can comprise EPS Bearer ID, NAS sequence number and NAS-MAC etc.

Alternatively, step 320, eNodeB transmits to adhere to new MME and accomplishes message (Attach Complete).

Receive adhere to accept message and UE and obtain the PDN address after, UE just can be to the eNodeB transfer uplink data, eNodeB will reach S-GW and P-GW with the user uplink link data through the tunnel.

Alternatively; Step 321; After receiving the initial context response message and adhering to completion message, new MME sends to S-GW and revises the request of carrying (Modify Bearer Request), can comprise the TEID of EPS Bearer ID, eNodeB address and downlink data receiving etc. in this request.

Alternatively, step 322, S-GW sends to new MME and upgrades bearing response message (Modify Bearer Response), can comprise EPS Bearer ID in this response message.

S-GW can send the downlink grouped data of its institute's buffer memory now.

The contracted user is attached to after the EPS system, and MME has set up the MM context for each contracted user, comprising IMSI and MTC sign; When transfer of data; The contracted user is to network initiated service request, if when under the network congestion situation, receiving the services request from the contracted user, it is the MTC contracted user that the record when MME adheres to through the contracted user in the MM context identifies this contracted user; Directly refuse this MTC contracted user's services request then, and with going up suitable cause value.Below be elaborated through accompanying drawing 4.

Fig. 4 is the service request flow chart of EPS system.As shown in Figure 4, this method also comprises:

Step 401, MME receives the services request that the contracted user sends, and this services request comprises user's temporary mark.

Particularly, as shown in Figure 4, step 401 can further comprise:

Step 401.1, contracted user's UE sends services request (Service Request) to eNodeB, wherein comprises user's temporary mark (S-TMSI) in this services request.

Step 401.2, eNodeB passes to MME with service request information, wherein comprises user's temporary mark (S-TMSI) in this services request.

Step 402, MME searches this contracted user's MM context or IMSI according to the S-TMSI in the message, and according to the sign of the MTC in the MM context, perhaps to the judgement of IMSI, confirms whether this contracted user is the MTC contracted user.

When in the present embodiment, this MTC sign is adhered to by this contracted user in the MM context record; Judgement to IMSI can be as previously mentioned.

Step 403, if MME confirms that this contracted user is the MTC contracted user, then when offered load was heavier, MME refused or postpones MTC contracted user's service request, and with going up suitable cause value.If the offered load situation is normal, carry out normal flow process.

Alternatively, this method also comprises step 404, if desired, will carry out network attachment storage (NAS, NetworkAttached Storage) authentication and safe procedures, and this flow process can be used existing techniques in realizing, does not give unnecessary details here.

Particularly, in the present embodiment, also can set up the EPS business, specifically can be like step 405 to 413 said.

Alternatively, step 405, MME sends initial context to eNodeB and sets up request (Initial Context SetupRequest).

This initial context is set up in the request can comprise S-GW address (S-GW address); S1-TEID (s) (UL); EPS bearer quality of service (EPS Bearer QoS (s)); Safe context (Security Context) and MME signaling connection identifier (MME Signalling Connection Id) etc.

In the present embodiment, eNodeB is with Security Context, and MME Signalling Connection Id, EPSBearer QoS (s) and S1-TEID are stored in user's wireless access network (RAN, Radio Access Network) context.

In the present embodiment, if this contracted user's of refusal service request in the step 403 comprises Reason For Denial (for example, network congestion) in the message of then returning in this step.

Alternatively, step 406, if allow contracted user's service request, eNodeB carries out radio bearer and sets up process (RadioBearer Establishment), the safety of user plane is also set up in this step.

In the present embodiment, if this contracted user's of refusal service request in the step 403 is then returned NAS message (Service Request Response) in this step, return Reason For Denial.

Alternatively, step 407, eNodeB mails to S-GW with contracted user's upstream data (Uplink Data).

ENodeB can utilize the S-GW address and the TEID that provide in the step 405 that data are upwards transmitted.S-GW mails to P-GW with user's upstream data.

Alternatively, step 408, NodeB sends S1-AP message (initial context is set up and accomplished Initial ContextSetup Complete) to MME.

Can comprise eNodeB address (eNodeB address) in this message; EPS carries and accepts tabulation (List ofaccepted EPS bearers); EPS carries refusal tabulation (List of rejected EPS bearers) and down link A1 TEID (s) (DL, Down Link) etc.

Embodiment 3

The embodiment of the invention is on the basis of embodiment 1; A kind of MTC contracted user's recognition methods is provided; Be applied in the packet-switched domain (PS territory, Packet Switched Domain) or circuit commutative field (CS territory, CircuitSwitched Domain) of UMTS system.Below be example with the PS territory of UMTS system, through adhere to/routing area update procedures carries out detailed explanation.

Fig. 5 adheres to/the routing region updating schematic flow sheet for the PS territory of UTMS system.As shown in Figure 5, this method comprises:

Step 501, new Serving GPRS Support Node (SGSN, Serving GPRS Support Node) obtains contracted user's ISMI.

In the present embodiment, as shown in Figure 5, step 501 can further comprise:

Step 501.1 is set up the NAS signaling and is connected (NAS SignalingConnection) between contracted user's UE and new SGSN.

Step 501.2, UE initiates attach request or routing region updating request (Attach/Routing Area Update Request) through the NAS signaling message to new SGSN;

If grouping Temporary Mobile sign indicating number (P-TMSI is arranged; Packet Temperate Mobile SubscriptionIdentity); Then carry P-TMSI and Tracking Area Identifier (RAI, RoutingArea Identity) in attach request or the routing region updating request; If there is not P-TMSI, then carry IMSI in attach request or the routing region updating request.

Alternatively, step 501.3 if UE uses P-TMSI to adhere to, and was adhered to from last time and have been changed SGSN, and new SGSN should send identification request (Identification Request) and give old SGSN, with P-TMSI that goes up the user and corresponding RAI.

If UE uses P-TMSI to carry out Routing Area Update and be to cross between SGSN; New SGSN sends the SGSN context request and gives old SGSN; This SGSN context request has the old P-TMSI of user, old RAI, old P-TMSI signature; With MM context and packet data protocol (PDP, the Packet Data Protocol) context that obtains the contracted user.

Alternatively, step 501.4 is if contracted user's signature is legal or through new SGSN authentication success, old SGSN responds SGSN context response information (Identification Response).

Wherein, can comprise Cause, IMSI, MM context and PDP Context etc. in this response message.

Alternatively, step 501.5, if the contracted user does not have effective P-TMSI, new SGSN will send identification request (Identity Request) to UE, request IMSI.

Alternatively, step 501.6 after UE receives identification request, reports this contracted user's IMSI to give new SGSN.

So far, new SGSN from UE obtained the contracted user IMSI, or obtained contracted user's IMSI from local or old SGSN through P-TMSI.

Step 502, new SGSN confirms that this contracted user is the MTC contracted user when comprising the hexadecimal notation of A to E any or its combination among the IMSI;

Particularly, step 502 can comprise:

Whether the MCC that judges IMSI exists the hexadecimal notation of any or its combination of A to E; If judged result is the hexadecimal notation that has any or its combination of A to E, then this contracted user is the MTC contracted user; Otherwise this contracted user is the H2H contracted user;

Whether the MNC that perhaps, judges IMSI exists the hexadecimal notation of any or its combination of A to E; If judged result is the hexadecimal notation that has any or its combination of A to E, then this contracted user is the MTC contracted user; Otherwise this contracted user is the H2H contracted user.

Whether all that perhaps, judge IMSI exist the hexadecimal notation of any or its combination of A to E; If judged result is the hexadecimal notation that has any or its combination of A to E, then this contracted user is the MTC contracted user; Otherwise this contracted user is the H2H contracted user.

Step 503, new SGSN writes down this contracted user in MTC contracted user's MM context be the MTC contracted user, for example increases the MTC sign.

Thus; PS territory in the UMTS system; The contracted user is when for the first time being attached to some SGSN or route to a new SGSN; New SGSN can from UE, or P-TMSI through the contracted user obtain contracted user's IMSI, new SGSN can identify through the judgement to IMSI whether the contracted user who is asked is the MTC contracted user, and when making up the MM context for this user, writes down this characteristic.

In the present embodiment, if current network is congested, new SGSN can directly refuse adhering to or routing region updating of MTC contracted user after identifying the MTC contracted user, and with going up suitable cause value, can normally carry out to guarantee H2H contracted user communication.

Alternatively, this method also can comprise step 504, if desired, will initiate authentication process.Further; In the present embodiment; The SGSN number changes after separating (being that UE is connected with the SGSN disconnection) last time if adhere to contracted user's the first time perhaps; Then SGSN also can search user contracting data for behind the MTC contracted user definite contracted user, specifically can be of step 505 to step 512.

Step 505, new SGSN initiates to upgrade position requests to attaching position register (HLR, Home Location Register), and this request has IMSI, also has SGSN number, SGSN address.

Step 506, HLR confirms according to IMSI whether this contracted user is the MTC contracted user; After confirming as the MTC contracted user, search user contracting data in MTC contracted user's subscription data district.

In the present embodiment, confirm that according to IMSI whether the contracted user is that the MTC contracted user specifically can adopt aforesaid method, repeats no more here.

Alternatively, step 507, HLR sends cancel location message (Cancel Location) and gives old SGSN.This message carries IMSI, cancellation type, and it is Update Procedure that the cancellation type is set simultaneously.

Alternatively, step 508, old SGSN sends canceling position response message (Cancel Location Ack), acknowledges receipt of the Cancel Location of HLR, and this response message carries IMSI.

If this contracted user has the flow process of any well afoot, old SGSN should wait for that these flow processs finish, and could delete contracted user's MM context and PDP Context then.

Alternatively, step 509, if the contracted user adheres to for the first time or the SGSN number changes after separating last time, HLR inserts user contracting data (Insert Subscribers Data) to new SGSN, this user contracting data carries IMSI.

Alternatively; Step 510; New SGSN confirms that the contracted user is present in the new route district, if user contracting data restriction contracted user adheres in this route district, SGSN should refuse contracted user's attach request; Band is responded simultaneously and is inserted subscription data acknowledge message (Insert Subscribers Data ACK) to HLR with appropriate cause value.

If subscription data inspection is because the other reasons failure, new SGSN should the refusing user's attach request, with going up suitable cause value, responds HLR simultaneously and inserts the subscription data acknowledge message, and this acknowledge message has IMSI, cause value.

If all subscription data inspections are passed through, new SGSN constructs the MM context for the contracted user, responds HLR simultaneously and inserts the subscription data acknowledge message, and this acknowledge message has IMSI.

Alternatively, step 511, HLR responds routing update acknowledge message (Update Location ACK) to new SGSN.

Alternatively, step 512, new SGSN responds to UE and adheres to or routing region updating is accepted message (Attach/Routingarea Update Accept), and this message comprises newly assigned P-TMSI, P-TMSI signature.

After the contracted user was attached to the UMTS system, SGSN had set up the MM context for each contracted user, comprising IMSI and MTC sign; When transfer of data; The contracted user is to network initiated service request, if when network is received the services request from the contracted user under congestion condition, the record when SGSN adheres to through the contracted user in the MM context identifies the contracted user into MTC; Directly refuse this MTC contracted user's services request then, and with going up suitable cause value.Below be elaborated through Fig. 6.

Fig. 6 is the services request flow chart of UMTS system.As shown in Figure 6, this method also comprises:

Step 601, SGSN receives the services request that the contracted user sends, and this services request comprises user's temporary mark.

Particularly, as shown in Figure 6, step 601 can further comprise:

Step 601.1 is at first set up the NAS signaling and is connected (NAS SignalingConnection) between contracted user's UE and SGSN;

Step 601.2, UE initiates services request (Service Request) through the NAS signaling message to SGSN, and this services request comprises user's temporary mark (TMSI), and this user's temporary mark can be TMSI or P-TMSI.

Step 602, SGSN searches this contracted user's MM context or IMSI according to this user's temporary mark, according to the sign of the MTC in the MM context, perhaps to the judgement of IMSI, confirms whether this contracted user is the MTC contracted user.

Step 603; If confirm that this contracted user is the MTC contracted user, then when network is in congestion state, SGSN will directly refuse or postpone this MTC contracted user's services request; And, can normally carry out to guarantee H2H contracted user communication with going up suitable cause value.

Alternatively, this method also comprises step 604, if desired, will initiate authentication process;

Alternatively, step 605, SGSN responds service to UE and accepts or refuse; If current network conditions is good; SGSN accepts contracted user's services request, can carry out follow-up RAB (RAB, Radio Access Bearer) appointment process and PDP Context then and set up process.

In the present embodiment; When UE need carry out transfer of data; At first will be at UE and Gateway GPRS Support Node (GGSN; GateWay GPRS Support Node) set up PDP Context between, below through setting up the process of PDP Context, to being elaborated to the optimization that GGSN brings with IMSI identification MTC contracted user.

Fig. 7 is a flow chart of between contracted user's UE and GGSN, setting up PDP Context.As shown in Figure 7, this method also comprises:

Step 701, when setting up block data protocol context for the contracted user, SGSN is according to the contracted user of the MM Context record for machine class communication contracted user, for the contracted user selects suitable GGSN.

Particularly, as shown in Figure 7, step 701 further comprises:

Step 701.1 is at first set up UE and is connected (NAS Signaling Connection) with NAS signaling between the SGSN.

Step 701.2, UE initiates PDP context activation request (Active PDP Context Request) to SGSN.

Step 701.3, SGSN selects suitable GGSN according to this contracted user's MM context for this contracted user.

In the present embodiment, SGSN can search this contracted user's MM context, confirms according to the MTC sign of MM context record whether this contracted user is the MTC contracted user, and can select suitable GGSN for this contracted user according to APN.

For example, disposed different GGSN if network is the H2H contracted user with MTC contracted user allocation of communications, then SGSN can be the GGSN that the MTC contracted user selects to be exclusively used in MTC.

Step 702, SGSN sends to selected GGSN with the contracted user for machine class communication contracted user's record, so that this GGSN is stored in the contracted user in contracted user's the block data protocol context for communicate by letter contracted user's record of machine class.

Particularly, SGSN can initiate PDP Context to selected GGSN and set up message (PDP Context CreateRequest), and wherein this message comprises the MTC sign.After GGSN receives this message, can be with the part of this MTC sign as MTC contracted user PDP Context.

In the present embodiment; When network congestion; GGSN can be according to the record of contracted user for machine class communication contracted user, refusal or the block data protocol context that postpones this contracted user set up request, or reduce this contracted user service quality guarantee, or discharge the data that this contracted user set up and connect.Specifically can be of step 703 to step 708.

Alternatively, step 703 is being carried out QoS when consulting, and GGSN passes to the QoS that its MTC sign and current network conditions and MTC contracted user asked according to SGSN and holds consultation.

If current network is in congestion condition, GGSN can indicate that refusal is MTC contracted user service or reduction MTC contracted user's QoS index or the data connection that the release user has set up according to MTC.

Alternatively, step 704, GGSN responds PDP Context to SGSN and sets up response message (PDP Context CreateResponse).

Alternatively, step 705, SGSN initiates RAB according to the QoS after consulting to UE and assigns process (RAB Setup).

Alternatively, step 706, SGSN sends PDP context activation response message (Active PDP ContextResponse) to UE.

So far, set up PDP and connected, between UE and GGSN, can carry out transfer of data (Data Transfer).

Alternatively, step 707, if certain the time network congestion taken place, GGSN can connect according to the PDP that the sign of the MTC in the PDP Context at first discharge the MTC contracted user, can normally carry out to guarantee H2H contracted user communication.

Alternatively, step 708, GGSN sends deletion PDP Context request (Delete PDP Context Request) to SGSN.

Can know by the foregoing description, in the PS territory of UMTS system, replace the decimal system to represent IMSI through adopting hexadecimal; Both can distinguish MTC contracted user and H2H contracted user, and can make the capacity of IMSI satisfy growing terminal use's demand again.And, when network congestion, can refuse or discharge MTC contracted user's service, protection H2H contracted user communication.

In addition; CS territory in the UMTS system, the contracted user for the first time is being attached to some VLR Visitor Location Registers (VLR, Visit Location Register) or is carrying out the band of position when being updated to a new VLR; VLR can obtain contracted user's IMSI; Whether VLR is the MTC contracted user through the judgement of IMSI is determined, and after confirming as the MTC contracted user, record MTC sign when making up the MM context for this contracted user.Corresponding flow process is described with above-mentioned similar with detailed process step, repeats no more here.

Because the communication of machine class almost do not have audio call, the short message service in CS territory is mainly used in the communication of current machine class, identify the MTC contracted user through IMSI after, can handle the MTC short message to the network optimization.Below be elaborated through accompanying drawing.

Fig. 8 is for distinguishing behind the MTC contracted user flow chart that short message is optimized processing through IMSI in the CS territory.As shown in Figure 8, this method also comprises:

Step 801, mobile switching centre (MSC, Mobile Switching Center)/VLR receives the short message that the contracted user sends, and this short message comprises contracted user's sign.

Particularly, contracted user's UE is sent to MSC/VLR through the NAS signaling with short message.

Step 802, MSC/VLR searches this contracted user's MM context or IMSI according to contracted user's sign;

Step 803, MSC/VLR according to the contextual contracted user of MM be the MTC contracted user record, or, judge whether this contracted user is the MTC contracted user to the judgement of IMSI;

Step 804, if confirm that the contracted user is the MTC contracted user, then MSC/VLR refuses perhaps to postpone to submit this short message when network congestion.

Alternatively, step 805, MSC/VLR can transmit short message to short message interoperability mobile switching centre (SMS-IWMSC, Short MassageService-InterWorking Mobile Switch Centre).

Alternatively, step 806, SMS-IWMSC is passed to SMS service center (SMS-SC, SMS ServiceCentre) with short message.

Alternatively, step 807, SMS-SC is passed to short messaging gateway mobile switching centre (SMS-GMSC, SMSGateWay Moble Switching Center) with short message.

Further, step 808 after SMS-GMSC receives this short message, is transmitted the needed routing iinformation of short message to the called HLR request, obtains from this HLR and transmits the needed routing iinformation of this short message.Wherein this routing iinformation comprises called contracted user's IMSI.

Step 809, SMS-GMSC judges according to this called contracted user's IMSI whether this called contracted user is the MTC contracted user;

Step 810, if confirm that this contracted user is the MTC contracted user, then SMS-GMSC refuses or postpones to submit this short message to the MSC/VLR at this called contracted user place when network congestion.

Alternatively, step 811, SMS-GMSC utilizes the routing iinformation that obtains from HLR that short message is forwarded to the MSC/VLR that called contracted user belongs to, and this short message comprises called contracted user's sign.

Further; Step 812; After the MSC/VLR at called contracted user place receives short message; Search this called contracted user's MM context according to called contracted user's sign, confirm for MTC contracted user's record whether this called contracted user is the MTC contracted user according to the contextual contracted user of MM.

Step 813, if confirm that this called contracted user is the MTC contracted user, the MSC/VLR at then called contracted user place is when network congestion, refusal perhaps postpones to submit short message to this called contracted user, preferentially submits H2H contracted user's short message.

Alternatively, step 814, the MSC/VLR at called contracted user place is passed to called contracted user through the NAS signaling with short message.

Can know by the foregoing description, in the CS territory of UMTS system, replace the decimal system to represent IMSI through adopting hexadecimal; Both can distinguish MTC contracted user and H2H contracted user, and can make the capacity of IMSI satisfy growing terminal use's demand again.And, when network congestion, can refuse or discharge MTC contracted user's service, protection H2H contracted user communication; Especially for MTC contracted user's short message, further optimization process.
