C3.MME selects an APN according to the system of selection of APN (can be that certain emergence call service is specified concrete APN), and and then obtain the SGW/PDN-GW that this APN represents; MME sends emergence call service control request message to this SGW/PDN-GW, comprises in the message: the sign of emergency telephone number, terminal, the PDN type of the urgent call carrying that desire is set up, PCO parameter;
C4.SGW/PDN-GW sets up record for described terminal in the carrying of this locality tabulation, the described terminal of this record permission is externally carried out the packet route between data network and SGW/PDN-GW; UL-TFT and DL-TFT according to emergency telephone number distributes a urgent call IP address and is suitable for this emergence call service carrying for this MME send to MME then and set up urgent call carrying request responding message; Comprise described be the urgent call IP address of terminal distribution and the UL-TFT of distribution in the described response message.
C5.MME receive SGW/PDN-GW set up emergence call service carrying request responding message after, for this terminal is set up the carrying record, and notify eNB to set up the initial context carrying, simultaneously issuing eNB for this terminal distribution urgent call IP address, parameters such as UL-TFT, PCO;
C6.eNB receives that MME sends set up the initial context bearer messages after, set up the initial context carrying, and send to terminal and to connect reconfiguration message; Comprise described be this terminal distribution urgent call IP address, parameters such as UL-TFT, PCO in the described connection reconfiguration message.
C7. terminal is set up radio bearer according to described connection reconfiguration message, and after radio bearer foundation is finished, returns foundation to the base station and finish response, terminal keeps the IP address of the terminal of receiving simultaneously, UL-TFT, service quality (Quality of Service, QoS) information such as parameter;
C8.eNB sends the response message of setting up the initial context carrying to MME;
C9. terminal sends the urgent call carrying by eNB to MME and sets up the message that finishes.
After the urgent call carrying is set up and is finished, terminal then can be used IP address allocated, rule according to UL-TFT sends upstream data, be appreciated that, after the urgent call carrying is set up and is finished, can also comprise MME and SGW/PDN-GW interactive refreshing relevant parameter in loading establishing process, concrete renewal process can be set up flow process with reference to default bearer of the prior art, and the present invention repeats no more.
Adopting the foregoing description one or embodiment two to set up on the basis of emergence call service carrying, terminal can be initiated the called urgent call of emergence call service number that is, the filter method of urgent call data is provided below.
Embodiment three, a kind of Emmergency call method, flow chart comprises as shown in Figure 4:
S1. the emergence call service of receiving mobility managed network element transmission identifies, and described calling on urgently makes service identification be positioned at described terminal in the middle of request message is set up in the carrying that described mobile management network element sends;
S2. be designated described terminal distribution IP address according to described emergence call service;
S3. described IP address allocated is sent to mobile management network element and set up radio bearer, and carry out urgent call by the radio bearer of setting up so that mobile management network element sends to terminal with described IP address.
In the embodiment of the invention, network gateway receives the IP address assignment request that has the urgency traffic sign, then direct distributing IP address, be appreciated that, present embodiment can also distributing IP address correspondence UL-TFT and DL-TFT to realize the filtration of follow-up packet to this IP address, concrete distribution method can be referring to the correlation step among the embodiment two.
On the said method basis, after terminal acquisition IP sets up radio bearer in the address, can realize the filtration of urgent call packet by network gateway, specifically describe by following examples four.
Embodiment four provides a kind of Emmergency call method, and flow chart comprises as shown in Figure 5:
D1. the up urgent call packet that sends of network gateway receiving terminal comprises the IP address and the target ip address of described terminal in the described urgent call packet;
The packet that is appreciated that the packet of network gateway receiving terminal or sends to terminal may pass through a plurality of network element transfers, for example: base station, MME etc.The network element of interim data bag may change to some extent according to the existing network architecture and communication protocol, and concrete network element is not construed as limiting the invention.
Because step D1 carries out setting up on the basis of radio bearer, also comprise before the described step D1: request message is set up in the carrying that comprises the urgent call sign that network gateway receiving mobility managed network element sends; Be designated described terminal distribution IP address according to described urgent call.
D2. if the IP address of described terminal is not effective emergence call service IP address or described target ip address is not the IP address of emergency telephone number binding, then with described urgent call data packet discarding.
Be appreciated that the embodiment of the invention four can also comprise: it is the descending urgent call packet of described terminal that network gateway receives purpose IP address; If the transmit leg IP address of described descending urgent call packet is not the IP address of emergency telephone number binding, then should descending urgent call data packet discarding.
The embodiment four-way is crossed the up emergency data bag of terminal is filtered, and can prevent that the disabled user from carrying out illegal communication by pretending to be the urgent call packet, makes that the fail safe of emergence call service is higher.
Embodiment five, a kind of Emmergency call method, flow chart comprises as shown in Figure 6:
T1. terminal sends carrying to network side and sets up request message, and described carrying is set up and comprised the emergence call service sign in the request message;
Be appreciated that in the embodiment of the invention, terminal and network side be that mobile management network element with network side carries out interacting message alternately, interactive messages can be transmitted by the base station for this Terminal Service.
T2. terminal receives network side according to described emergence call service sign IP address allocated;
In the present embodiment, described IP address is that network gateway distributes, and sends to mobile management network element, the terminal of mobile management network element by for the base station of Terminal Service IP address allocated being issued.
T3. terminal is set up radio bearer according to described IP address, and initiates urgent call by the radio bearer of setting up.
In the present embodiment, increase the urgent call sign in the request by setting up in the carrying of terminal, network side then can know that this is to set up request for the carrying that urgent call is set up according to this sign, ignore various safety inspections to this user's SIM card, be this terminal distribution IP address, terminal receives that the IP address then can use this IP address to set up radio bearer, and by radio bearer initiation urgent call, finally realized urgent call, simplified the communication equipment and the network equipment and reduced networking cost with respect to prior art at the PS network.
Embodiment six, a kind of Emmergency call method, flow chart after setting up radio bearer by the step of embodiment five, can also comprise the steps: as shown in Figure 7
