Step 101, user uses calling terminal MS to dial emergency service number, and emergency service number is identified by the discernible emergency numbers of network side and an expansion service and forms, and this expansion mark can identify the service bearer demand of current emergency services effectively.
Different with the access way of network side according to calling terminal type, aforementioned emergency calling can be the emergence call service based on circuit-switched CS domain, packet switched ps domain or IMS network mode.
For based on circuit-switched CS domain, what calling terminal MS dialed is made up of emergency numbers ' 110 ' on conventional meaning and expansion service mark ' 9 ', this expansion mark ' 9 ' service bearer demand that effectively can identify current emergency services is an one way traffic carrying, namely unidirectional voice and video.
Preferably, calling terminal also can use Short Message Service SMS to trigger corresponding emergency service request, such as it sends relevant character string to an emergency numbers, and emergency numbers is made up of emergency numbers ' 110 ' on conventional meaning and expansion service mark ' 9 '.
For based on IMS network mode, calling terminal initiates the Invite request of urgent call, it comprises emergency telephone number and previous extension service identifiers in Request URI, and the access way of oneself, source address, previous extension service identifiers can be write this header field providing in P-Access-Network-Info header field by calling terminal; And add own IP address at Contact header field.Previous extension service identifiers can be used for marking it in service bearer demands such as the unidirectional carrying of voice/video Packet data service demand, bandwidth requirement or grouped data priority height in a packet switched network.
Step 102, mobile network switching center MSC, after receiving emergency call request, can not conveniently first judge the flow processs such as the call authority of calling subscriber but directly start urgent call process, and its command M GW1 is the service bearer that calling terminal MS sets up.
Such as: receive that user dials ' 1109 ', it is to dialed number combine digital analysis, last expansion service mark 9, according to the particular traffic requirements being about decided to be customization urgent call, mobile network switching center MSC sends one and is specifically indicated to selected media gateway MGW 1, such as: MSC adds a new flag bit to notify that it sets up an one way traffic bearer path between MGW1 and calling terminal MS in the H248Add Commands issuing MGW1, to transmit one-way video or audio resource, namely network side can be heard according to the Equipments Setting of calling terminal or see the situation of user side, and calling terminal MS can not sound and show call.
