Abstract
A method for determining a server which should respond to a service request from a mobile device, said method comprising: Generating a DNS request which comprises a URI to identify a service requested by said mobile device and in addition to the URI of the requested service an indication of the location of the mobile device; inserting into said DNS request a keyword, which identifies said service DNS request as being a service which is enabled for service migration; forwarding said DNS request to a DNS server; determining by said DNS server a most suitable server responding to said service request, said determination being based on the location of the mobile device as indicated by said indication of the location added to said URI; returning the address of said server which has been determined based on said location to said mobile device.
