The invention discloses data transmission method and device based on a relay mobile communication system. The method comprises the steps of allocating at least two transmission planes on a Un interface protocol stack between a relay station RS and a base station eNode B; and transmitting data between the RS and the eNode B through at least two transmission planes allocated on the Un interface protocol stack. The invention can improve the throughput rate of a Un interface between the RS and the eNode B in the relay mobile communication system, and reduce the time relay of the Un interface.

The invention provides a method, apparatus and system for acquiring network information. The method comprises: when a mobile station needs local network information, the mobile station sending request message of local network information to an access gateway according to whether acquired access gateway supports the local network information visited by the mobile station; the mobile station receiving response returned by the access gateway, the response comprising local network information distributed to the mobile station by the access gateway. By using the invention, unnecessary information interaction between the mobile station and the access gateway is reduce, when the mobile station moves, large transmission time delay is avoided.

The invention discloses a method for minimizing downlink transmission delay based on the NOMA-MEC system. First, a system model of a base station equipped with a mobile edge computing server and K mobile users is constructed, wherein the base station and users are equipped with a single antenna for Signal transmission and reception; according to the transmission characteristics of the downlink NOMA and the characteristics of the MEC system, the user's signal-to-noise ratio, transmission bit constraints, power constraints and energy consumption constraints are derived; then, the mathematics for the purpose of minimizing the system delay is constructed. model; finally, an optimization algorithm is designed to obtain the optimal resource allocation scheme aiming at minimizing the delay. The invention solves the problem of unbalanced delay and energy efficiency in the downlink transmission process of the existing NOMA-MEC system in the multi-user scenario, and can reduce the transmission delay of the system under the common constraints of computing tasks, power and energy consumption. to a minimum.

The invention discloses a method for authenticating short message service comprising: short message center judges if the calling user is user of intelligent network; when the user is intelligent network user, SC inquire account information of calling user from SDP database, authenticates if the calling user possesses short message sending authority according to inquiry result. The No.7 signalling network is suitable for inquiring the message leaving out steps that SC switches to IP network via charging gateway and user database is inquired through IP network. The inventive method promotes transmission reliability of inquiring message, avoids time delay of delivery likely occur to IP network, facilitates account centralized management for mobile intelligent network, promotes network resource utilization rate.

The invention discloses a method for automatically controlling receiving channel gains and a device. The method includes the steps that the receiving-end device calculates receiving channel gain adjustment values corresponding to antenna receiving channels through receiving signals corresponding to the antenna receiving channels; the receiving-end device selects the receiving channel gain adjustment value with the minimum absolute value from the receiving channel gain adjustment values corresponding to the antenna receiving channels; the receiving-end device determines the receiving channel gains currently corresponding to the receiving channel gain adjustment value with the minimum absolute value; the receiving-end device sets the receiving channel gains of the antenna receiving channels to be the receiving channel gains currently corresponding to the receiving channel gain adjustment value with the minimum absolute value; the receiving-end device carries out corresponding adjustment on the receiving channel gains of the antenna receiving channels through the receiving channel gain adjustment value with the minimum absolute value. By means of the method and the device, huge time-frequency resource waste and huge service face transmission delay can be avoided.
