Abstract: A system installed at a roaming mobile network, comprises: a signaling relay enabled to monitor, intercept and modify mobile network signaling messages between the roaming network and the home network, a controller application for the signaling relay, said controller configured to instruct the signaling relay to replace an identity of a roaming user with a local network subscriber identity, thereby to enable registration of the roaming user with the local network for receiving at least one local mobile service as a local user, the roamer retaining a pre-existing registration with a respective home mobile network for receiving at least one other roaming mobile service, wherein authentication of the mobile device with the roaming network uses authentication data of the home network registration.

Abstract: A method, system and gateway for control of calls unanswered by a roaming user roaming on a roaming network, comprises monitoring outward bound calls to roaming users, monitoring subsequent inward forwarding of those calls terminated without answering at said roaming users, and matching between the outward bound and inward forwarding. Matching confers control of processing of the terminated call in two ways. One is that it allows call details, typically lost over International networks, to be obtained regarding the terminated call. Secondly, it allows the originating call to be connected directly to the voicemail or other forwarding destination without involving any International connections.

Abstract: Apparatus located at a first mobile telephony network, said network comprising a detector for detecting at least one of roaming registration signals and session management signals of roaming mobile telephony users of said first mobile telephony network who are roaming at another mobile telephony networks; and an analytics unit, associated with said detector, for analyzing said detected signals per individual roaming users, and identifying, from said signals, any one of a plurality of predefined cost saving behaviors of respective individual roaming users. The analytics unit provides an identification output for any of said individual roaming users who is identified to be engaging in one of said predefined cost saving behaviors.

Abstract: A global location register (GLR) provides a proxy for visitor location registers to the home location registers to avoid updating of the external network with location update notifications upon transfer of a roaming user between visitor location registers. The standard GLR is extended by being configured with multiple addresses, has a soft shutdown procedure, has a blacklist mechanism, a searching facility for finding lost roaming users, and has a mechanism for overcoming ambiguities in local identification numbers assigned by visitor location registers.

Abstract: The CAMEL standard allows a roaming user to have his call or any other telephony service, say SMS and GPRS, controlled and services provided from his home network. The invention allows infrastructure triggers to be intercepted at the roaming network so that the roaming network can identify the roamer and make use of the triggers to provide services. This is possible irrespective of whether the roamer's home network supports the infrastructure.

Abstract: A remote preference unit for influencing visited network selection by roaming mobile units, comprises a detection signaling relay/probe on International signaling connections, for detection of roaming activity by mobile units, a database indicative of preferred networks in the given country that the network operator prefers his roamers to use, application logic with certain criteria, determining the output, and an output unit, associated with said detection probe and said database to output indications to influence network selection by said detected roaming mobile units. In one embodiment the output is simply a rejection of the location update signal that forms the roaming request. In an alternative embodiment the signal is a copy of the relevant section of the database which is uploaded to the SIM card of the roaming unit. The SIM card upgrade may or may not be accompanied by a stage of forcing the handset to re-initiate the network selection process.

Abstract: Apparatus for identification of locations within a cellular network subject to loss of roaming users, comprises a monitoring unit for monitoring International controlling signaling of the cellular network, a register for registering cancel signals associated with roaming cellular telephones leaving the cellular network, and a query unit, for responding to the cancel signals by issuing a query to identify a current cell location of the cellular telephone. The cell locations indicated can then be aggregated to show where there are problems with leakage of roaming users.
