A method of enabling inter-mobile network proximity services through a direct link between mobile communication devices attached to different mobile networks, the method comprising: selecting and configuring at least one first mobile communication device attached to a first mobile network among said different mobile networks for the acquisition of configuration data related to proximity services of at least a second mobile network among said different mobile networks, said configuration data related to proximity services comprising information about radio resources assigned in said second mobile network for the proximity services; having the selected and configured first mobile communication device report the acquired configuration data related to proximity services of the at least a second mobile network to at least one between: the first mobile network, and at least one second mobile communication device located in proximity of the first mobile communication device.

Method and system for enabling inter-PLMN proximity services

A method for controlling a heterogeneous wireless network () is proposed. The heterogeneous wireless network comprises at least one first base station () which manages communication of a plurality of first user equipments (M) positioned in at least one first cell () and at least one second base station () which manages communication of a plurality of second user equipments () positioned in at least one second cell (). Moreover, in the heterogeneous network (), for each first user equipment (M) the at least one first base station () provides a respective first allocation information set over a respective first allocation time interval. Similarly, the at least one second base station () provides for each second user equipment () a respective second allocation information set over a respective second allocation time interval. Furthermore, each first allocation information set and each second allocation information set define transmission resources for communications of each first user equipment (M) and of each second user equipment (M), respectively. In the heterogeneous wireless network (), the at least one second cell () is at least partially comprised in the first cell (). The method comprises the following steps. Said at least one first base station determines () a set of probably interfering first user equipments () with at least one of the plurality of second user equipments (). Said step of determining the set of probably interfering first user equipments () comprises the following steps. Comparing each second allocation information set with each first allocation information set having the first allocation time interval at least partially overlapped with the respective second allocation time interval, and identifying as a probably interfering first user equipment () each first user equipment () for which a correspondence is verified in said comparing allocation information sets. The method further comprises the following steps. Said at least one second base station () defines a detection time window in order to analyze univocal identifiers transmitted by probably interfering first user equipments () in said set. The method comprises identifying () a subset of effectively interfering first user equipments () with the plurality of second user equipments (). Said at least one first base station () modifies () said transmission resources for at least one first user equipment () comprised in the subset of effectively interfering first user equipments () in order to mitigate interferences.

A method allows the selection of a user-preferred visited mobile network for a roaming mobile terminal of a subscriber of a home network. The method includes, at the home network, the steps of receiving information on the location of the roaming mobile terminal, and receiving from the roaming mobile terminal service information including at least a choice of a service and controlling the selection of the visited mobile network for the roaming mobile terminal on the basis of the received service information and location information.

Method for interactive mobile network selection

In a wireless communications network having a base station subsystem controlling at least one network cell, and in which the base station subsystem communicates with mobile stations in the cell through radio blocks, a method of distributing information contents received in data packets at the base station subsystem to the mobile stations, includes obtaining, starting from the data packets, radio blocks to be transmitted through the network cell, labeling the radio blocks with a first radio link identifier, identifying a logic connection between a mobile station and the base station subsystem, communicating the first radio link identifier to a first mobile station in the network cell, and in case at least one second mobile station in the network cell, asks to receive the information contents, communicating thereto the first radio link identifier. The method further includes having the first mobile station and the at least one second mobile station assigned respective second radio link identifiers to be included in the radio blocks.
