Method for relay selection based on composite multi-interface load metric

A vehicle unit comprising a communication unit for communication in a vehicle of a user to a at least one base station comprising a microprocessor, volatile and non-volatile memory and at least one communication interface, which are communicatively connected to the at least one base station or further communication subscribers via one or more mobile communication lines, wherein the system (100) is adapted to perform operations, for Relay Selection based on Multi-Interface Load Metric between communication subscribers, on the part of the at least one base station for establishing communication, the operations comprising:

• Determining local and thematic information for determining communication subscribers;
• Determining a group of communication subscribers based on the local and thematic information, wherein a local area is defined for local restriction of the communication subscribers and wherein at least one of a technological aspect and an interest-related aspect is used for thematic restriction on the part of the base station;
• characterized in that,
• granting permission to communicate data from a group of communication subscribers to the at least one base station is established via further communication subscribers by using discovery mechanisms between them.
