Embodiment
With reference to Fig. 1, this figure is that the embodiment of the invention realizes the once flow chart of complete emergency call service, comprises the steps:
The information on services of step 101, server stores emergency call service, information on services comprise unified resource identifiers, URIs (Uniform Resource Identifier) or the pairing geographic range information of service number, the service of being supported and the sub-services information of each concrete emergency call service.
The unified resource identifier of emergency call service or service number are used for user and emergency call service and communicate and get in touch.The unified resource identifier that oneself can be arranged as each police office.In addition as each police office oneself compass of competency geographic range is all arranged, what such geographic range information was also corresponding is stored in the server.The concrete emergency call service that each police office provided also can be called an emergency call service example.
The sub-services information of supporting refers to the service item that this service can provide, and the emergency services project that can provide as different police office may be different, and some conventional emergencies may can only be handled in little police office, possibly can't handle major events such as terrorist activity.This sentences police's service (urn:service:sos.police) and is example, and its sub-services that provides can comprise stealing (theft), plunder the processing of (robbery) and terrorist activity (terrorism) or the like incident.
Emergency call service example that step 102, user end to server acquisition request are concrete and the sub-services information of being supported comprise the geographical location information of client in the described request, and the title of the emergency call service of being asked etc.
Client can be arranged in mobile devices such as mobile phone or portable machine.After the start or to network registry the time, the address that obtains server earlier obtains emergency call service information from server again.As passing through Wireless Fidelity Wi-Fi (Wireless Fidelity) access network at mobile device, and by dynamic host configuration protocol DHCP (Dynamic Host Configuration Protocol) when obtaining the IP address, obtain to store the server address of emergency call service information simultaneously.Client is obtained emergency call service information from this server then, uses when in order to future emergency taking place.Because the position of mobile device also needs constantly to upgrade with position corresponding with service information in constantly changing.In the information on services that client gets access to, can also comprise the geographic range information that each concrete server administers, when client shifts out the geographic range that the server administered, resend the pairing information on services of acquisition request and active client position.Client also can be obtained the information on services corresponding with current location as sending refresh requests half an hour automatically at regular intervals.Can also remove to obtain information on services when the user uses client to select emergency call service, the information that such mode obtains is more accurate.
Client can obtain the unified resource identifier of the emergency call service corresponding with own position, as SIP URI, sip:szpd@example.gov.Can comprise a plurality of different URI, can also comprise that service number is as 28560110 etc.Can also distribute different URI to different sub-services in addition, and return to client together.Client can be contacted directly and the own required corresponding URI of sub-services when follow-up generation emergency like this, makes the processing of emergency more efficient.
Step 103, when emergency takes place, subscription client makes a call to the unified resource identifiers, URIs of emergency call service, can comprise needed sub-services information in call request.Perhaps, if comprise the concrete URI of sub-services correspondence in the sub-services information that server returns, then can directly call the URI of sub-services correspondence.Concrete communicate etc., and in the message of INVITE method, comprise needed sub-services information as initiating to set up a session with the INVITE method of Session Initiation Protocol.
Concrete operating process can be: select police's service of emergency call service at the operation interface of subscription client, corresponding police's information on services with current location is being obtained in the prompting of client display message, and can show existing police's information on services of buffer memory simultaneously, the information of buffer memory may be not too accurate, if but very urgent situation can allow the user carry out urgent call according to existing information on services, and needn't wait for.After obtaining new police's information on services, show new police's information on services.The police's information on services that shows can comprise the title in police office and the sub-services project of support etc., after selecting one or more sub-services projects, and the click-to-dial button, client will be got in touch corresponding URI and be communicated.
A kind ofly show better that in client the mode of police's information on services is after the user selects the police service of emergency call service, show at present available sub-services tabulation, the user is as long as select needed sub-services, because user and to be indifferent to be who handles urgent call on earth.
Client also can show whole sub-services tabulations, arranges demonstration by the degree commonly used of sub-services.If the user has selected a sub-services, and this sub-services is not in any one police that it gets access to serves the sub-services that URI supports, at this moment client can send the request of the corresponding URI of this concrete sub-services of an inquiry, this request comprises the current geographic position information of the title and the client of sub-services, and server can return police one or more and that the client current geographic position information is the most approaching and serve URI.Client is initiated urgent call to this URI again.
Be example mainly in the embodiment of the invention with police's service (urn:service:sos.police), but be not limited to this, other some services are as fire-fighting (urn:service:sos.fire), maritime affairs (urn:service:sos.marine), medical first aid emergency services or some counseling services such as children (urn:service:counseling.children) such as (urn:service:sos.ambulance), also all be suitable for the present invention equally, enumerate no longer one by one herein.
