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.
