Claims (11)

1. Fremgangsmåde til styring af fordeling af indhold til en mobil entitet (20; 36), hvor den mobile entitet (20; 36) har en første grænseflade (21) til at kommunikere med et mobilt kommunikationsnetværk (2, 4, 5) og en anden grænseflade (22) til at danne et ad-hoc-netværk (101,102) med en anden mobil entitet (25-27; 37-39), hvilken fremgangsmåde udføres af en indretning (10; 92) til styring af fordeling af indhold til den mobile entitet (20; 36), omfattende: - at modtage via det mobile kommunikationsnetværk (2, 4, 5) en anmodning (73; 80) fra den mobile entitet (20; 36), hvilken anmodning (73; 80) indeholder en indholdsidentifikator (81), der identificerer indholdet; - at bestemme baseret på den modtagne anmodning (73; 80) en region (30), hvori den mobile entitet (20; 36) befinder sig; - at hente baseret på indholdsidentifikatoren (81) informationer om andre mobile entiteter (25-27; 37-40), som deltager i deling af indholdet, hvor informationerne omfatter lokationsinformationer for de andre mobile entiteter (25-27; 37-39); - at identificere en undermængde af de andre mobile entiteter (25-27; 37-39) baseret på de hentede lokationsinformationer og på den bestemte region (30); og - at verificere baseret på de hentede lokationsinformationer, om et stabilitetskriterium til dannelse af ad-hoc-netværket (101, 102) er opfyldt, - hvor, hvis stabilitetskriteriet er opfyldt, det bestemmes, at et skift fra en fordeling af indholdet via det mobile kommunikationsnetværk (2, 4, 5) til en fordeling af indholdet via ad-hoc-netværket (101, 102) skal gennemføres af den mobile entitet (20; 36) ved at: - overføre via det mobile kommunikationsnetværk (2, 4, 5) en besked (75) til den mobile entitet (20; 36), hvilken besked (75) indeholder en peer-adresse af en mobil peer-entitet (25-27; 37-39) indeholdt i den identificerede undermængde, hvilken peer-adresse gør det muligt for den mobile entitet (20; 36) at hente mindst en del af indholdet via ad-hoc-netværket gennem den anden grænseflade (22) fra den mobile peer-entitet (25-27; 37-39).
2. Fremgangsmåde ifølge krav 1, hvor beskeden (75) yderligere indeholder en kildeadresse, som gør det muligt at hente indhold via det mobile kommunikationsnetværk (2, 4, 5) i en sikkerhedsprocedure.
3. Fremgangsmåde ifølge krav 1, hvor verificeringen indeholder bestemmelse af en densitet af mobile entiteter (20, 25-27; 36-39), som deltager i deling af indholdet i den bestemte region (30).
4. Fremgangsmåde ifølge et af de foregående krav, yderligere omfattende: bibeholdelse af mapping-informationer (13; 93), som definerer en mapping mellem første adresser anvendt i det mobile kommunikationsnetværk (2, 4, 5) og anden adresser af andre mobile entiteter anvendt i ad-hoc-netværket (101, 102) indeholdt i de hentede informationer.
5. Fremgangsmåde ifølge et af de foregående krav, hvor ad-hoc-netværket (101,102) er et køretøjs-ad-hoc-netværk (101, 102).
6. Fremgangsmåde ifølge et af de foregående krav, yderligere omfattende: for en flerhed af regioner (30, 43) overvågning af et antal af mobile entiteter, der befinder sig i den respektive region (30, 43) for at forudsige en overbelastning i et radionetværk (4), hvor hentningen og identificeringen udføres selektivt baseret på en forudsagt overbelastning.
7. Fremgangsmåde ifølge et af de foregående krav, hvor regionen (30) er indeholdt i regioner (30, 43), der anvendes til at identificere mobile entiteter, der befinder sig i nærheden af hinanden, hvilke regioner (30, 43) indeholder en tile eller flere tiles af en geo cast-tjenesteydelse.
8. Indretning til styring af fordelingen af indhold til en mobil entitet (20; 36), hvilken indretning (10; 92) omfatter: - en grænseflade (11) til at modtage via et mobilt kommunikationsnetværk (2, 4, 5) en anmodning (73; 80) fra den mobile entitet (20; 36), hvilken anmodning (73; 80) indeholder en indholdsidentifikator (81), som identificerer indholdet; - en behandlingsenhed (12), som er tilkoblet grænsefladen (11) og konfigureret til - at bestemme baseret på den modtagne anmodning (73; 80) en region (30), hvori den mobile entitet (20; 36) befinder sig; - at hente baseret på indholdsidentifikatoren (81) informationer om andre mobile entiteter (25-27; 37-40), som deltager i deling af indholdet, hvor informationerne omfatter lokationsinformationer for de andre mobile entiteter (25-27; 37-39); - at identificere en undermængde af de andre mobile entiteter (25-27; 37-39) baseret på de hentede lokationsinformationer og på den bestemte region (30); og - at verificere baseret på de hentede lokationsinformationer, om et stabilitetskriterium til dannelse af ad-hoc-netværket (101, 102) er opfyldt, - hvor, hvis stabilitetskriteriet er opfyldt, det bestemmes, at et skift fra en fordeling af indholdet via det mobile kommunikationsnetværk (2, 4, 5) gennem en første grænseflade af den mobile entitet (20; 36) til en fordeling af indholdet via ad-hoc-netværket (101,102) gennem en anden grænseflade af den mobile entitet (20; 36) skal gennemføres af den mobile entitet (20; 36), og - at overføre via det mobile kommunikationsnetværk (2, 4, 5) en besked (75) til den mobile entitet (20; 36), hvilken besked (75) indeholderen peer-adresse af en mobil peer-entitet (25-27; 37-39) indeholdt i den identificerede undermængde, hvilken peer-adresse gør det muligt for den mobile entitet (20; 36) at hente indholdet via ad-hoc-netværket (101, 102) gennem den anden grænseflade (22) fra den mobile peer-entitet (25-27; 37-39).
