A method of forwarding packets from an LTE network to at least one subnet , said LTE network comprising a core network with a Packet Gateway , PGW, and a plurality of LTE cellular equipment connected to said core network, said at least one subnet comprising a given LTE cellular equipment of said plurality of LTE cellular equipment and at least one other associated cellular equipment, said at least one subnet being managed by said given LTE cellular equipment acting as a hosting cellular equipment, the method comprising the steps of: - defining, in the PGW, subnet relationships between a subnet and a cellular equipment address of the hosting cellular equipment, and upon receipt at the PGW of a downlink packet with a destination address: - checking the validity of the subnet relationships by determining which subnets are associated to which cellular equipment address by a subnet relationship, checking that a subnet does not conflict with a cellular equipment address, checking that the cellular equipment address matches an address allocated by the PGW and by checking that subnet relationships do not conflict with each other; and - checking whether the destination address is part of a subnet relationship and, if so, locate the associated cellular equipment which is part of this subnet relationship; and, checking whether the located cellular equipment is connected to the core network or not and, if yes, forwarding the downlink packet only in case of validity over a bearer to the hosting cellular equipment and the subnet which are part of said subnet relationship. - defining, in the PGW, subnet relationships between a subnet and a cellular equipment address of the hosting cellular equipment, and upon receipt at the PGW of a downlink packet with a destination address: - checking the validity of the subnet relationships by determining which subnets are associated to which cellular equipment address by a subnet relationship, checking that a subnet does not conflict with a cellular equipment address, checking that the cellular equipment address matches an address allocated by the PGW and by checking that subnet relationships do not conflict with each other; and - checking whether the destination address is part of a subnet relationship and, if so, locate the associated cellular equipment which is part of this subnet relationship; and, checking whether the located cellular equipment is connected to the core network or not and, if yes, forwarding the downlink packet only in case of validity over a bearer to the hosting cellular equipment and the subnet which are part of said subnet relationship. - checking the validity of the subnet relationships by determining which subnets are associated to which cellular equipment address by a subnet relationship, checking that a subnet does not conflict with a cellular equipment address, checking that the cellular equipment address matches an address allocated by the PGW and by checking that subnet relationships do not conflict with each other; and - checking whether the destination address is part of a subnet relationship and, if so, locate the associated cellular equipment which is part of this subnet relationship; and, checking whether the located cellular equipment is connected to the core network or not and, if yes, forwarding the downlink packet only in case of validity over a bearer to the hosting cellular equipment and the subnet which are part of said subnet relationship. <EOS>
