Advanced geocasting methods in mobile communication networks, and network nodes therefor

摘要

A method provides a network service in a communication network covering a geographical area for a plurality of mobile clients. A mobile client (among the plurality of mobile clients) registers with the communication network. A geomessaging register identifies a service enabler based on registration information of the mobile client. The geomessaging register sends, to the identified service enabler, contact information of the mobile client. The service enabler sends, to the geomessaging register, contact information of the service enabler. The geomessaging register then sends, to the mobile client, the contact information of the service enabler. The mobile client is then connected to the service enabler for receiving the network service. Related network nodes participate in providing such services.

1. A method for providing a network service in a communication network covering a geographical area for a plurality of mobile clients, the method comprising:
registering a mobile client to the communication network, the mobile client being one of the plurality of mobile clients; identifying, among a plurality of service enablers, a service enabler by a geomessaging register based on a registration information of said mobile client, wherein
each service enabler is configured to address mobile clients in a designated geographical area; andthe geomessaging register is configured to keep track of the geographical areas covered by each of the service enablers; sending, by the geomessaging register to the identified service enabler, a contact information of said mobile client; sending, by the service enabler to the geomessaging register, a contact information of the service enabler; sending, by the geomessaging register to the mobile client, said contact information of the service enabler; connecting the mobile client to the service enabler for receiving the network service; notifying a server of a location of said mobile client and the geomessaging register of said client registration; subscribing said geomessaging register to the server; and notifying said geomessaging register by the server of said client location.
