At first introduce the urgent method that inserts of UE that the embodiment of the invention provides, in case of emergency user inserted when this method can realize that the user does not have IMSI or IMSI invalid, perhaps inserted the user who inserts when limited in case of emergency.Below describe by the urgent access of UE in evolvement network and UMTS network respectively:

With reference to Fig. 3, be urgent method one flow chart that inserts of UE in the embodiment of the invention, UE common urgent access in evolvement network below is elaborated by concrete steps:

301, UE and eNB set up Radio Resource control (RRC, Radio Resource Control) after the connection, UE sends Attach Request message to eNB, and the parameter of carrying in the request message has: urgent call attribute information, PDN address assignment (PDN Address Allocation), protocol configuration option (ProtocolConfiguration Options), type of attachment (Attach Type), request (Follow on request), user ID subsequently;

Wherein, the urgent call attribute information is used to indicate network side UE will carry out urgent call, for example, can be urgent call indication, urgent call type, perhaps for particular requirement of urgent call etc.;

PDN Address Allocation shows whether UE carries out IP address assignment and addresses distributed type;

Protocol Configuration Options is used for passing a parameter between UE and PGW, MME and this parameter of SGW transparent transmission;

Whether Follow on request indication network discharges S1 after finishing and connects adhering to; Attach type points out the type of adhering to;

For user ID, following two kinds of situations are arranged:

(1) when UE does not have IMSI, user ID is International Mobile Station Equipment Identification (IMEI, International Mobile Equipment Identity);

(2) when UE has IMSI, user ID has 2 kinds of possibility: IMSI; Old global unique temporary identity (GUTI, Global Unique Temporary Identity) or old tracking area identification (TAI, TrackingArea Identity).

UE informs that by Protocol Configuration Options PGW is that it selects a P-CSCF with particular procedure ability (as: support to use the anonymous mode directly to set up emergent session and need not carry out the IMS registration).

PDN Address Allocation and Follow on request are provided with by UE when normally adhering to, and can be provided with by MME when emergency attached.

UE can reserve interface-free resources in advance at urgent call/urgent call type;

UE is before sending Attach Request message, send RRC connection request message to eNB and set up the RRC connection, can in " reason " of RRC connection request message, increase " emergency attached " indication eNB urgent call, also can be by the combination indication " emergency attached " of a plurality of parameters.UE also indicates " urgent call type (as: fire alarm, traffic accident) " by the special parameters of RRC connection request message; Indicate " requiring to keep RRC to connect " by the special parameter in the RRC connection request message, be understandable that, UE also can adopt other urgent call identification information indication eNB urgent call.

302, eNB selects MME and transmits Attach Request message to this MME, and MME selects pre-configured urgent call QoS information and carrying to set up mode on MME according to urgent call attribute information in the Attach Request message;

Urgent call QoS information can be: about the Qos information of urgent call or the Qos information relevant with specific urgency traffic and urgent call particular requirement, and can be according to the urgent call type or for the particular requirement of urgent call configuration urgent call QoS information.

Establish following mode for emergency bearing:

(1) between UE～PGW, set up a general emergency bearing, this carrying both can carrier signaling also can the bearer service data;

(2) between UE～PGW, set up a urgent default bearer, and may be during this process or afterwards, initiate to set up urgent dedicated bearer by network node (as: MME, PGW, PCRF, eNodeB);

(3) between UE～PGW, can set up some emergency bearings synchronously.

The parameter that is used to indicate urgent call of carrying according to UE in RRC connection request message or the Attach Request message, eNB allocates user's face resource in advance, as: user's face address and tunnel destination node sign (TEID, Tunnel End Point Identifier), and together with adhering to request issue MME; The eNB use is configured in the last urgent call Qos information of eNB and dispatches interface-free resources in advance.

303, can be according to operator's needs, MME uses user ID to come to confirm to EIR (Equipment Identity Register equipment identity register) request user's identity by identity checks message, if the user is in blacklist, MME adheres to request with refusal so;

Be understandable that whether need authentication process, depend on the strategy of operator for emergency attached.Can be the urgent special configuration authentication vector that inserts on network element node M ME, carry out authentication process.

304, MME selects SGW and PGW, and sets up bearing request message to selected SGW transmission;

MME can select SGW and PGW in the following way:

(1) after MME identified urgent call, MME used local Em-APN (the urgent APN of Emergency-AccessPoint Name) to obtain inserting PGW and the SGW of urgency traffic PDN;

(2) " urgent PGW " and " promptly SGW " that can insert urgency traffic PDN by network is configured in MME.

MME can be according to the specific urgency traffic type or the urgency traffic particular requirement of UE indication, selection is configured in local urgent call Qos information, set up bearing request message to the SGW transmission, carrying parameter comprises: urgent call Qos information, Em-APN, user ID, PDN Address Allocation, ProtocolConfiguration Options, bearing identification, wherein bearing identification is distributed by MME.

If in step 302, eNB is that emergency bearing is allocated user's face address and TEID in advance, and then MME carries this parameter to SGW in setting up bearing request message.In this message, whether at once PDNAddress Allocation represents the distributing IP address, and under emergency call situations, this will be changed to distributing IP address immediately, and MME can require branch to be used in the particular ip address of particular type urgent call.Follow on request is set to not discharge S1 by MME and connects after adhering to, i.e. being connected between Access Network side apparatus and the core-network side equipment.These two parameters all are to be forced to be provided with by MME owing to the needs of urgency traffic, after the setting, can effectively guarantee the reliability of emergency bearing.

305, SGW allocation of downlink user face and control plane address and TEID, and send to PGW and to set up bearing request message, carry parameter in the message: user's face and control plane address and TEID that urgent call Qos information, Em-APN, user ID, bearing identification, PDN Address Allocation, Protocol Configuration Options, SGW distribute;

If 306 have disposed policy and charging control (PCC, Policy and Charging Control) network, PGW can carry out alternately with PCRF so, and PCRF can trigger the foundation in advance of dedicated bearing voluntarily according to the needs of urgency traffic;

307, PGW distributes up user's face and control plane address and TEID, PGW sends and sets up bearing response message to SGW, carry user's face and control plane address and TEID, PDN Address Information that parameter: PGW distributes in the message, bearing identification, Protocol Configuration Options;

Wherein, PDNAddress Information is that PGW is the UE IP address allocated.

308, SGW allocation of downlink user face and control plane address and TEID, SGW sends and sets up bearing response message to MME, carries parameter in the message: user's face and control plane address and TEID, PDNAddress Information, Protocol Configuration Options, bearing identification;

309, MME sends to adhere to and accepts message to eNB, carry the user's face address and the TEID of parameter: Em-APN, PDNAddress Information, Protocol Configuration Options, bearing identification, tracing area sign (TAI, Tracking Area Identity) tabulation, SGW distribution in the message;

Wherein, if MME has distributed GUTI to UE, also should carry this parameter of GUTI in the message.

The TAI tabulation is that MME issues UE tracing area identification list.

If the scheduling of 310 interface-free resources finishes, eNB sends radio bearer to UE and sets up request message so, and this message is carried the NAS message attachment and accepted;

If the interface-free resources scheduling is not finished, wait for so after scheduling is finished sending this message.

311, UE sends radio bearer to eNB and sets up response message, and this message is carried the NAS message attachment and finished;

312, eNB transmits to adhere to and finishes message to MME, carries parameter in the message: bearing identification;

If 313 set up many emergency bearings, can or trigger PGW by PCRF and set up dedicated bearing by PGW;

314, UE carries out IMS territory Emmergency log-on;

When UE used IMS territory anonymous, UE can carry out IMS territory Emmergency log-on.

315, the emergent session in IMS territory is set up.

For urgent call Qos information, can be configured in as required on each network element node, for example, can include but not limited to eNB, MME, PGW and PCRF, when only being configured in a network element node, need be by increasing the network element node that parameter informs that other need in particular message or the existing message.Also can be in pre-configured other parameters such as carrying number that need be that urgent call is set up of each network element node.For urgent call Qos information may be that one group of Qos ensemble of communication is corresponding to specific urgency traffic or urgency traffic particular demands.

As seen, in this method, MME receives and triggers the emergency bearing of setting up between the eNB that sets up and the PGW behind the Attach Request message, and the eNB side carrying of eating dishes without rice or wine of being set up after the scheduling interface-free resources, can realize the emergent session in IMS territory, realize that the user promptly inserts.

517, the emergent session in IMS territory is set up.

With reference to Fig. 6, be urgent method one embodiment three flow charts that insert of UE in the embodiment of the invention, in the present embodiment, UE still adopts IMEI as user ID, can set up many emergency bearings, but with embodiment two in to set up the method for carrying different, below be elaborated by concrete steps:

601, identical with step 401 among method one embodiment one, repeat no more;

602, eNB selects MME and transmits Attach Request message to this MME;

Because be urgent call, so network need be in advance at the carrying number of eNB configuration urgent call QoS information and use, specifically can be: eNB be that emergency bearing (comprising dedicated bearing and default bearer) is allocated user's face address and TEID in advance.

According to urgent call sign in the RRC connection request message or the urgent call attribute information in the Attach Request message, eNB allocates user's face resource in advance, as user's face address and TEID, and issues MME together with Attach Request message; ENB uses the urgent call Qos information that is configured on the eNB to dispatch interface-free resources in advance.

603, identical with step 403 among method one embodiment one, repeat no more;

604, MME selects SGW and PGW, and sets up the dedicated bearing request message and set up the default bearer request message to selected SGW transmission;

MME distributes bearing identification, and can select to be configured in local urgent call Qos information according to the specific urgency traffic type or the urgency traffic particular requirement of UE indication.

MME carries parameter to setting up of SGW transmission in the default bearer request message: urgent call Qos information, Em-APN, IMEI, PDN AddressAllocation, Protocol Configuration Options, bearing identification.

If in step 602, eNB is that default bearer has been allocated user's face address and TEID in advance, and then MME carries this parameter to SGW in setting up the default bearer request message.In this message, whether immediately PDNAddress Allocation represents the distributing IP address, under emergency call situations, this parameter is set to distributing IP address immediately, and MME can require branch to be used in the particular ip address of particular type urgent call.Follow on request is set to not discharge S1 by MME and connects after adhering to.These two parameters all are to be forced to be provided with by MME owing to the needs of urgency traffic, can effectively guarantee the reliability of emergency bearing.

MME carries parameter to setting up of SGW transmission in the dedicated bearing request message: urgent call Qos information, related bearing identification (linked Bearer id), IMEI, bearing identification reach and are urgent dedicated bearing pre-assigned user's face address and TEID, wherein, linked Bearer id is the sign of default bearer;

MME will set up the default bearer request message and set up the dedicated bearing request message and send together.

605, SGW is default bearer and dedicated bearing distributing user face and control plane address and TEID respectively, and will set up the default bearer request message and set up the dedicated bearing request message and send together;

Wherein, set up and carry parameter in the default bearer request message: user's face and control plane address and TEID that urgent call Qos information, Em-APN, IMEI, bearing identification, PDN Address Allocation, Protocol ConfigurationOptions, SGW distribute;

Set up and carry parameter in the dedicated bearing request message: urgent call Qos information, linked Bearerid, IMEI, bearing identification, and SGW be user's face address and the TEID that urgent dedicated bearing distributes.

If 606 have disposed the PCC network, PGW can carry out alternately with PCRF so;

607, PGW is respectively default bearer and dedicated bearing distributes up user's face and control plane address and TEID, and will set up the default bearer response message and set up the dedicated bearing response message and send to SGW together;

Wherein, set up the user's face and control plane address and TEID, the PDN Address Information that carry parameter: PGW distribution in the default bearer response message, bearing identification, Protocol ConfigurationOptions; Wherein, PDN Address Information is that PGW is the UE IP address allocated.

Set up and carry parameter in the dedicated bearing response message: linked Bearerid, IMEI, bearing identification, and PGW be user's face address and the TEID that urgent dedicated bearing distributes; If MME does not carry urgent call Qos information in step 604, PGW use on it configuration or from the urgent call Qos information that PCRF obtains, send to SGW;

608, SGW is respectively default bearer and dedicated bearing allocation of downlink user's face and control plane address and TEID, and will set up the dedicated bearing response message and set up the default bearer response message and send to MME together;

Wherein, set up and carry parameter in the default bearer response message: user's face and control plane address and TEID, PDN Address Information, Protocol Configuration Options, bearing identification.

Set up and carry parameter in the dedicated bearing response message: user's face and control plane address and TEID, bearing identification, linked Bearer id.If carry urgent call Qos information in the step 606, then SGW carries this parameter.

609, MME sends simultaneously to adhere to and accepts message and carrying is set up request message to eNB;

Wherein, adhere to user's face address and the TEID that accepts to carry in the message parameter: Em-APN, PDN Address Information, Protocol Configuration Options, bearing identification, TAI table, SGW distribution; If MME has distributed GUTI to UE, adhere to and accept also should carry in the message this parameter of GUTI.

Carrying is set up and is carried parameter in the request message: user's face address and TEID, linked Bearer id that bearing identification, SGW distribute.

If the scheduling of 610 interface-free resources finishes, eNB sends radio bearer to UE and sets up request message so, and this message is carried the NAS message attachment and accepted;

611, UE sends radio bearer to eNB and sets up response message, and this message is carried the NAS message attachment and finished;

612, eNB sends to adhere to and finishes message and carrying is set up response message to MME, and, carry bearing identification in the message respectively;

613, UE carries out IMS territory Emmergency log-on;

Carry out the registration of IMS territory and promptly can be carried on the dedicated bearing, also can be carried on the default bearer.

614, the emergent session in IMS territory is set up.

Be understandable that, UE uses IMSI as user ID, and when being in the roaming confined area during start, also can realize urgent the access, as required, can set up an emergency bearing by setting up carrying, also can set up many emergency bearings, concrete grammar and method one embodiment one, embodiment two, embodiment three are roughly the same, and difference is that UE need carry out could setting up emergent session after the Emmergency log-on.

For UE IMSI is arranged, when being in the roaming confined area during UE start, UE can also use old GUTI and old TAI as user ID earlier, set up one or more emergency bearing, wherein, old GUTI is the sign that the MME at the original place of UE distributes to UE, with reference to Fig. 7, be urgent method one embodiment four flow charts that insert of UE in the embodiment of the invention, below be elaborated by concrete steps:

701～702, UE sends to the new MME of new selection by eNB and adheres to request;

Before request is adhered in transmission, need set up RRC between UE and the eNB equally and connect, and it is identical with step 401 among processing concrete grammar and method one embodiment one to set up parameter entrained in method that RRC connects and the Attach Request message, repeats no more.Difference is that UE uses old GUTI and old TAI as user ID.

703, new MME obtains IMSI by the old MME that old GUTI and old TAI obtain the original place of UE to old MME request;

If 704 do not obtain IMSI in step 703, new MME asks IMSI to UE;

705, can be according to operator's needs, MMM comes identity to EIR request user by identity checks, if the user in blacklist, MME adheres to request with refusal;

If the carrying that 706～707 new MME have this UE to activate, new MME deletes the carrying that activates about this UE on it;

708～721, identical with 404～417 cardinal principles among method one embodiment one, difference is that user ID is IMSI, but not IMEI describes no longer one by one.

Equally, because IMSI is as user ID, UE need carry out could setting up emergent session behind the Emmergency log-on.

More than urgent cut-in method in the evolvement network is described in detail by specific embodiment, below introduce UE and realize the urgent method that inserts by the UMTS system:

With reference to Fig. 8, be the urgent method two flow chart that inserts of UE in the embodiment of the invention, when inserting by the UMTS system, two kinds of situations are arranged, a kind of is that core-network side is SGW, PGW, and under this scene, SGSN is equivalent to the MME in the evolvement network, another kind is that core-network side is GGSN, below is elaborated by concrete steps:

801, UE sends Attach Request message with after RNC sets up RRC and is connected to SGSN, carries parameter in the message: urgent call attribute information, AttachType, Follow on Request, user ID;

Wherein, the urgent call attribute information is used to indicate network side UE will carry out urgent call, specifically can be urgent call indication, urgent call type, perhaps for particular requirement of urgent call etc.; Whether Follow onrequest indication network discharges S1 after finishing and connects adhering to, and is provided with by UE when normally adhering to, and is provided with by SGSN when emergency attached; Attach type is used to point out the type of adhering to;

For user ID, following two kinds of situations are arranged:

(1) when UE did not have IMSI or IMSI invalid, user ID was IMEI;

(2) when UE has IMSI, user ID can be IMSI, can also be P-TMSI and old RAI;

Before UE sends Attach Request message, need set up RRC with RNC and be connected, can in " reason " of RRC connection request message, increase " emergency attached " indication RNC urgent call, also can be by the combination indication " emergency attached " of a plurality of parameters.UE also indicates " urgent call type (as: fire alarm, traffic accident) " by the special parameters of RRC connection request message; Indicate " requiring to keep RRC to connect " by the special parameter in the RRC connection request message, be understandable that, UE also can adopt other urgent call identification information indication RNC urgent call.

The parameter that is used to indicate urgent call according to the UE that carries in RRC connection request message or the Attach Request message, RNC uses the urgent call Qos information be configured on the RNC to dispatch interface-free resources in advance, and described urgent call Qos information can be according to the urgent call type or for the particular requirement setting of urgent call.

802, can be according to operator's needs, SGSN comes identity to EIR request user by identity checks message, if the user in blacklist, then the SGSN refusal adheres to request;

803, SGSN sends to adhere to and accepts message to UE;

If SGSN has distributed new P-TMSI, then adhere to and accept to carry this parameter in the message;

Follow on Request is provided with by UE when normally adhering to, and can be provided with by SGSN when emergency attached, and indication does not discharge Iu after adhering to and connects, with the priority and the reliability of the emergency bearing that guarantees to be set up;

If carried the P-TMSI parameter in 804 steps 803, then UE finishes message indication and receives P-TMSI by adhering to;

805, according between UE and core net node, emergency bearing is set up;

When inserting by the UMTS system, two kinds of situations are arranged, a kind of is that the core-network side node is SGW, PGW, and under this scene, SGSN is equivalent to the MME in the evolvement network, and another kind is that the core-network side node is GGSN, and specific implementation can be referring to following specific embodiment.

806, UE carries out the IMS territory and registers;

807, IMS territory emergent session is set up.

When UE promptly inserts by the UMTS network, receive the Attach Request message that UE sends by SGSN, and by the emergency bearing attribute information in this message, select the urgent call QoS information of configuration and will set up the mode of carrying, and when receiving the activation PDP Context request message of user's transmission, can realize that to selected urgent core-network side node GGSN that inserts or PGW send connection and set up request, set up the emergency bearing of RNC to selected core-network side node, and dispatch pre-assigned interface-free resources by RNC, set up the side carrying of eating dishes without rice or wine.
