Abstract

The present invention relates to a method for providing peer-to-peer emergency service in a peer-to-peer network. The method comprises receiving a peer-to-peer emergency request (2). Said request (2) comprises an identifier relating to the origin (110) of the request (2). The identifier is used to identify the network access provider at the origin (110) of the request (2). The location of the origin (110) of the request (2) is retrieved from said network access provider (150). The invention also relates to a emergency service peer (100) for providing peer-to-peer emergency service.

Claims

1. Method for providing peer-to-peer emergency service in a peer-to-peer network, the method comprising the steps of

receiving a peer-to-peer emergency request, said request comprising an identifier relating to the origin of the request,

using said identifier to identify the network access provider at the origin of the request, and

retrieving the location of the origin of the request from said network access provider.

2. Method according to claim 1, further comprising the step of

sending a signalling message to the public safety answering point appropriate to said retrieved location.

3. Method according to claim 1, wherein

said identifier being the IP address of the origin of said request.

4. Method according to claim 1, wherein

said identifier being a pseudonym of the origin of said request,

said pseudonym being known to the network access provider and being received together with said request.

5. Method according to claim 1, wherein

identity federation in between the peer-to-peer network and the network access provider, and said identifier being a pseudonym of the origin of said request, upon which the peer-to-peer network and the network access provider have agreed.

6. Method according to claim 1, further comprising

the identification of the network access provider at the origin of the request using said identifier is done using an internet registry,

preferably a regional internet registry.

7. Node for providing peer-to-peer emergency service comprising

an input adapted to receive a peer-to-peer emergency request, said request comprising an identifier relating to the origin of the request,

means adapted to identify the network access provider at the origin of said request using said identifier, and

means adapted to retrieve the location of the origin of the request from said network access provider.

8. Node according to claim 7, wherein

means adapted to send a signalling message to the public safety answering point appropriate to said retrieved location.

9. Node according to claim 7, further comprising

said means adapted to identify the network access provider at the origin of said request using said identifier are further adapted to use an internet registry, preferably a regional internet registry,

for said identification.
