Fig. 4 is a fourth embodiment of the invention apparatus structure sketch map.
Embodiment
To combine accompanying drawing that example embodiment of the present invention is described hereinafter.In order to know and for simplicity, in specification, not describe all characteristics of actual execution mode.Yet, should understand, in the process of any this practical embodiments of exploitation, must make a lot of decisions specific to execution mode, so that realize developer's objectives, and these decisions may change along with the difference of execution mode to some extent.
When the user initiates urgent call in the IMS network, customer position information added in the sip message transmit.The mode of obtaining user profile has following several kinds:
(1) terminal obtains positional information.Carry positional information by accessing terminal, this mode is higher to demanding terminal, and needs the whole network unified;
(2) Session Border Controller (session Border Controller is hereinafter to be referred as SBC) structure terminal user position information.
When SBC does under the situation that the Full Proxy pattern inserts the IMS network, positional information is not handled at the terminal, and by the unified structure of SBC, the Access Network information that goes up configuration like terminal source IP address or SBC is as customer position information.
To mode one and mode two; If the customer position information that carries is an IP address of terminal; Can be by Proxy Call Session Control Function (Proxy-call Session Control Function; Hereinafter to be referred as P-CSCF) obtain this user's corresponding position information according to the connection of IP address lookup position and the memory function (connectivity session location andrepository function is hereinafter to be referred as CLF) at terminal.
(3) the signatory fixed position of user information.Under the user terminal location fixing situation; Can be when signatory; The record terminal positional information; By emergency call session controlled function/service call conversation control function (Emergency-call Session Control Function/Serving-call Session Control Function is designated hereinafter simply as E-CSCF/S-CSCF) customer position information from home subscriber server (Home SubscriberServer is designated hereinafter simply as HSS) acquisition fixed network users when registering.For the calling party who registers, then can in calling procedure, obtain customer position information from HSS.In emergency calling process, if when terminal, SBC or P-CSCF do not provide customer position information, E-CSCF/S-CSCF obtains customer position information from HSS.
Said method is a method of obtaining customer position information in the IMS network usually, and other can realize that the method for obtaining customer position information also is applicable to the embodiment of the invention.
First embodiment of the invention provides urgent call in the IMS network to transmit the method for customer position information to the CS network, and is as shown in Figure 1, comprising:
Step 101: the newly-increased Location-Information field of said customer position information being added to the header field of sip message.
Alternatively, said newly-increased Location-Information field is positioned at the P-Access-Network-info header field of said sip message.
Alternatively, said newly-increased Location-Information field is positioned at the newly-increased header field of said sip message.
Step 102: send the sip message that carries said customer position information arrives said CS network through the network element with IMS network and CS network interworking gateway function public safety answering point.
The unified field of the embodiment of the invention through the emergency call user positional information being added to sip message sends to the public safety answering point of CS network from the IMS network, can conveniently confirm customer position information, practiced thrift the urgent call processing time.
Second embodiment of the invention provides urgent call in a kind of IMS network to transmit the method for customer position information to the CS network, and is as shown in Figure 2, comprising:
Step 201: the user initiates urgent call, obtains customer position information.
Step 202: the newly-increased Location-Information field of the customer position information that obtains being added to the P-Access-Network-info header field of sip message.
Each field in the prior art in the P-Access-Network-info header field of sip message is used for carrying different customer position informations.Newly-increased Location-Information field is all added various types of customer position informations to this Location-Information field in the present embodiment, makes things convenient for the public safety answering point of CS network fast, accurately to confirm customer position information.
Step 203: the sip message that customer position information is carried in transmission is to the network element with IMS network and CS network interworking gateway function.
The sip message that carries customer position information is sent to the network element with IMS network and CS network interworking gateway function, make this urgent call of carrying customer position information be delivered to the public safety answering point of CS network.
Step 204: the network element with IMS network and CS network interworking gateway function reads customer position information from sip message.
Network element with IMS network and CS network interworking gateway function receives the sip message that this carries the emergency call user positional information, and the Location-Information field from the P-Access-Network-info header field of sip message reads customer position information.
Step 205: the location number cell that customer position information is filled up to arrowband signaling IAM message.
Have customer position information that the network element of IMS network and CS network interworking gateway function will read from the Location-Information field the P-Access-Network-info header field of sip message and be filled up to the location number cell of arrowband signaling initial address message (Initial Address Message is designated hereinafter simply as IAM).
Step 206: the public safety answering point that sends arrowband signaling IAM message to CS network.
After customer position information being filled up to the location number cell of arrowband signaling IAM message, this arrowband signaling IAM message is dealt into the public safety answering point of CS network.
Step 207:CS network obtains the customer position information of emergency call user.
The public safety answering point of CS network can be through the positional information of carrying in the location number cell in the IAM message after receiving this urgent call, and inquiry obtains corresponding more specific location information in the information database of position.
In the another embodiment of the present invention, the user initiates urgent call at the IMS network, obtains customer position information, customer position information is added to the newly-increased Location-Information field of the newly-increased header field of sip message.Transmission is carried the sip message of this customer position information to the network element with IMS network and CS network interworking gateway function.Network element with IMS network and CS network interworking gateway function receives that the newly-increased Location-Information field from the newly-increased header field of sip message reads customer position information behind this sip message; And this customer position information added to the location number cell of arrowband signaling IAM message; The public safety answering point of arrowband signaling IAM message to the CS network of customer position information is carried in transmission; The public safety answering point of CS network is after receiving this urgent call; Can be through the positional information of carrying in the location number cell in the IAM message, inquiry obtains corresponding more specific location information in the information database of position.
