Fig. 7 is the schematic flow sheet according to the implementation method of the emergency message of the embodiment of the invention one, and this implementation method can may further comprise the steps (step S702-step S710):
Step S702, P-CSCF 30 receives the message request that UE sends, and judges that described message request is an emergency message;
For example, when the user need initiate urgent call, the user sent message request by UE to an emergency telephone number (for example, 119,110 etc.), and this message request arrives the P-CSCF (being P-CSCF 30 in embodiments of the present invention) of the current network of living in of UE.
P-CSCF 30 is after receiving this message request, and P-CSCF 30 these message request of judgement are that the mode of emergency message includes but not limited to following two kinds:
Mode one, at UE before emergency telephone number sends this message request, UE can determine that this message request is an emergency message, then UE inserts the sign of indicating emergency message in this message request that sends, after P-CSCF receives message request, whether comprise the sign of indicating emergency message in the message request that receives by judgement, judge whether this message request is emergency message;
For example, UE can be inserted into the sign of indicating emergency message in the request address in this message request.
Adopt this mode, P-CSCF 30 is after receiving message request, and the short message format packaging body content that does not need to resolve in this message request can judge that just whether this message request is emergency message, has improved the judging efficiency of P-CSCF 30.
Mode two, P-CSCF 30 are after receiving message request, short message format packaging body content in this message request is tested, the called identification of therefrom obtaining this message request (for example, called number), judge whether this called identification is an emergency telephone number, if then judging this message request is an emergency message, otherwise this message request is not an emergency message.Adopt this mode, do not need UE to insert the sign of emergency message in message request, UE can send message request according to the mode that sends the common message business, and is lower to the Capability Requirement of UE.
Step S704, P-CSCF 30 send to this message request the E-CSCF32 of current network;
Step S706, E-CSCF 32 obtains the address of the suitable PSAP 38 of the sign of urgent short message service center 36 of current network and current network, short message service center's sign of the message request that receives is revised as the sign of urgent short message service center 36, and the address of in message request, inserting PSAP 38, then this message request is sent to E-IP-SMS-GW 34;
In this step, E-CSCF 32 obtains the sign of urgent short message service center 36 and the address of PSAP 38 includes but not limited to following three kinds of modes:
Mode one, in step S704, when P-CSCF 30 judges that this message request is emergency message, P-CSCF 30 is according to the urgent short message service center (being urgent short message service center 36 in embodiments of the present invention) that this UE distributes a locality that is configured to of network, and the request address in the message request is revised as the sign of urgent short message service center 36, after E-CSCF 32 receives this message request, resolve in this message request, therefrom get access to the sign of urgent short message service center 36; The address that E-CSCF can obtain PSAP according to following any method.
Adopt this mode, E-CSCF 32 can directly obtain the sign of urgent short message service center from message request, has improved the efficient that E-CSCF 32 handles.
Mode two, E-CSCF 32 is after the message request that receives P-CSCF 30 transmissions, to address server (Location Retrieval Function, abbreviate LRF as) inquiry UE positional information, LRF is after receiving query requests, inquire about the positional information of this UE, and according to the positional information of this UE, in current network, distribute an appropriate emergency short message service center (urgent in embodiments of the present invention short message service center 36) for this UE, and find a suitable PSAP (in embodiments of the present invention for PSAP 38), then with the positional information that inquires, the sign of urgent short message service center 36 and the address of PSAP 38 are carried at and return to E-CSCF 32 in the response message, and E-CSCF 32 parses the positional information of UE from response message, the sign of urgent short message service center 36 and the address of PSAP 38;
For example, LRF can select nearest urgent short message service center and PSAP from UE.
Adopt this mode, is that UE distributes urgent short message service center and PSAP by LRF according to the UE current position information, can guarantee that the urgent short message service center and the PSAP that distribute are and the urgent short message service center and the PSAP of UE current location coupling to guarantee that further the flash request that the user sends can be handled timely.
Mode three, in this mode, UE can have user's current position information in message request, E-CSCF 32 can parse the positional information of UE from the request message that receives, from current network, select urgent short message service center (in embodiments of the present invention be urgent short message service center 36) and the PSAP 38 corresponding then, and then obtain the sign of urgent short message service center 36 and the address of PSAP 38 with this positional information;
For example, E-CSCF 32 can select nearest urgent short message service center and PSAP from UE.
By this mode, E-CSCF 32 parses the positional information of UE from message request, and is that UE distributes urgent short message service center and selects PSAP according to this positional information, has avoided the Signalling exchange between E-CSCF 32 and the LRF, has simplified flow process.
Step S708, E-IP-SMS-GW 34 is converted to the short message request with the request message that receives, the called identification of short message request is set to the address of PSAP 38, short message service center's sign of this short message request is set to the sign of urgent short message service center 36, then this short message request is sent to urgent short message service center 36;
Step S710, urgent short message service center 36 receives above-mentioned short message request, according to the called identification (being the address of PSAP 38) of this short message request this short message request is sent to PSAP 38, for the user provides corresponding service.
Need to prove, the urgent short message service center 36 of current network can build separately, also can be set together with the short message service center of a locality, if urgent short message service center 36 is located at local short message service center, then the sign of urgent short message service center can comprise: this short message service center's number and urgent call sign.For example, the number of short message service center is 123456, promptly is designated A, and then the number of urgent short message service center can be 123456A, also can be A123456.
In the correlation technique, no matter whether be the message request of emergency message, this message request all is that the short message service center by user ascription area sends to the recipient's, for emergency message, if the user roams into other network, because the urgent short message service center and the PSAP of visit net can't be known in the short message service center of ownership place, thereby may cause urgent short message can't be delivered to the urgent short message service center and the PSAP of user visiting net, and then cause user's flash request to can not get handling timely.And in the implementation method of the emergency message of the embodiment of the invention, the P-CSCF 30 of visit net is when receiving message request, judge when this message request is emergency message, this message request is sent to the E-CSCF 32 of current network, and further this message request is sent to the urgent short message service center 36 of current network, urgent short message service center 36 by current network delivers emergency message to suitable PSAP 38, thereby the flash request that guarantees the user can access processing timely.
