A COMMUNICATION METHOD IN THE USER NETWORK AND A SYSTEM THEREOF

摘要

A communication method in the user network and a system thereof include: before the point-to-point connection is created, two UEs in the user network request the management entity for the security authentication of the corresponding UE via the access network, and the point-to-point connection is created until the certification of the corresponding UE is passed. The management entity may provide the key to the certificated UE to ensure the security of the data transmission. If two UEs are in the same personal area network, the point-to-point connection is the direct connection in the personal area network range. If two UEs are not in the same personal area network, the point-to-point connection is the remote connection created by the respective access network. By using the invention, the security of the data transmission among the UEs in the user network is ensured.
