Server and data transfer method

Abstract

Server and data transfer method. The present invention proposes a server, including: a terminal determining unit, which determines a target terminal for service sharing when receiving a service request sent by any terminal, or detecting that there is a service on the network side that needs to be shared; a generating unit, according to the The target terminal generates the service network topology information corresponding to the service; the network determination unit determines the bearer network corresponding to the service according to the service network topology information. Correspondingly, the present invention also provides a data transmission method. Through the technical scheme of the present invention, the trust and incentive problems in the terminal direct connection communication network can be solved, the security of data sharing can be improved, and the cross-layer optimization between the physical domain network and the business domain network can be realized.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular, to a server and a data transmission method. Background technique [0002] The introduction of terminal direct communication (direct communication) technology provides technical support for improving spectrum utilization efficiency, improving system throughput, reducing energy consumption of user equipment, and reducing operating costs of operators. The current 3GPP network has launched a The research on terminal direct communication technology defines various application scenarios of terminal direct communication technology. In the current research on terminal direct connection communication technology on the network side, the main focus is on the method of establishing a terminal direct connection communication network on the physical layer, for example, how to establish a terminal direct connection communication network between two user equipments. [0003] In the...

Problems solved by technology

[0004] However, in the current 3GPP standardization process, the main concern is how to establish terminal direct communication between two user equipments, which relies on "two user equipments that meet the physical establishment conditions of terminal direct communication (such as being close enough) The assumption that both terminal direct communication can be realized” does not take into account the authentication and incentives of user equipment, nor does it consider whether the user equipment in terminal direct communication is safe and trustworthy for data transfer transmission, nor does it Consider the potential business model problem (incentive problem) of data transfer, there is no realistic business model to support the implementation
