Local discovery of mobile network services involves coupling a communications device to a local network segment of a mobile data network. An announcement is sent from the communication device and/or a network entity (such as a network proxy) describing a service available via the respective devices. The announcement is receivable by any device on the local network segment. A request is received at the device for a detailed description of the service information in response to the announcement. A description of the service is sent from the communications device to the originator of the request in response to the request, and the service is established between the originator and the communication device and/or network entity in response to the sending of the description of the service
