An application server ( 113 ) receives, from a client mobile terminal ( 101 ), a request to initiate a first client application session, as well as first client specific data, where the data comprises a first mobile terminal identifier, e.g. a mobile station integrated services digital network number and a hash code. An association is made in the server ( 113 ) of a first client session identifier with the first mobile terminal identifier. The first client session identifier is then stored in a session management database ( 115 ). Maintenance of communication between the client terminal ( 101 ) and the application session is then enabled, including receiving a communication request and verifying that the communication request originate from the first client terminal ( 101 ).
