Abstract

An information transmission method and apparatus for a mobile terminal is provided. A method comprises: determining an uplink transmit power of the mobile terminal; and sending, in response to that the uplink transmit power falls within a preset range, to at least one forwarding node, indication information for instructing to forward measured data of the mobile terminal. According to the method and apparatus of the embodiments of the present application, forwarding of measured data is triggered according to an uplink transmit power of a mobile terminal, so as to facilitate reducing signaling overheads and delay caused by unnecessary forwarding, thereby improving the forwarding efficiency.

First claim

What is claimed is:

1. A method for transmitting measured data from a first mobile terminal to a second mobile terminal, comprising:
determining, by the first mobile terminal comprising a processor, an uplink transmit power of the first mobile terminal, wherein the uplink transmit power of the first mobile terminal is a maximum uplink D2D transmit power of the first mobile terminal, and according to the maximum uplink D2D transmit power of the first mobile terminal, a first maximum coverage area of a D2D signal of the first mobile terminal is estimated;
sending, by the first mobile terminal in response to determining that the uplink transmit power falls within a preset range that corresponds to a second maximum coverage area external to which the second mobile terminal is located, to at least one forwarding node whose distance from a base station is no greater than another distance of the first mobile terminal from the base station, indication information for instructing the at least one forwarding node to forward measured data of the first mobile terminal, wherein the indication information comprises the measured data, a forwarding request for the measured data, and a forwarding priority of the measured data, wherein the measured data comprises information associated with at least two elements selected from a moving speed of the first mobile terminal, a location of the first mobile terminal, a moving direction of the first mobile terminal, or a braking of the first mobile terminal, and wherein the preset range is determined by the first mobile terminal or the base station according to at least a transmission requirement of the measured data, a congestion level of a transmission channel, a geographical location of the first mobile terminal, and a density of other mobile terminals in a region in which the first mobile terminal is located; and
stopping, by the first mobile terminal in response to determining that the uplink transmit power does not fall within the preset range, the sending of the forwarding request to the at least one forwarding node, wherein the stopping the sending of the forwarding request comprises at least simultaneously sending the measured data to the at least one forwarding node.

2. The method of claim 1 , further comprising
sending, by the first mobile terminal, the measured data in response to determining that a response to the forwarding request is received.

3. The method of claim 2 , further comprising:
determining, by the first mobile terminal, a resource configuration associated with the measured data, and
wherein the sending, to the at least one forwarding node, the indication information for instructing to forward the measured data of the first mobile terminal comprises:
sending the indication information to the at least one forwarding node according to the resource configuration.

4. The method of claim 3 , wherein the determining the resource configuration associated with the measured data comprises:
sending a resource configuration request to another base station of a cell to which the first mobile terminal attaches; and
receiving configuration information associated with the resource configuration.

5. The method of claim 1 , further comprising:
after the sending, to the at least one forwarding node, the indication information for instructing to forward the measured data of the first mobile terminal, sending, by the first mobile terminal, the indication information to the at least one forwarding node by using at least a dedicated short range communications (DSRC) technology.

6. The method of claim 1 , wherein the sending, to the at least one forwarding node, the indication information for instructing to forward the measured data of the first mobile terminal comprises:
sending the indication information to the at least one forwarding node by using at least a device to device communications technology.

7. The method of claim 1 , wherein the at least one forwarding node comprises another base station of a cell to which the first mobile terminal attaches.

8. An apparatus for transmitting communications from a first mobile terminal to a second mobile terminal; wherein, the apparatus belongs to the first mobile terminal and the apparatus comprises:
a memory that stores executable modules; and
a processor, coupled to the memory, that executes or facilitates execution of the executable modules, the executable modules comprising:
a first determining module configured to determine an uplink transmit power of the first mobile terminal, wherein the uplink transmit power of the first mobile terminal is a maximum uplink D2D transmit power of the first mobile terminal, and according to the maximum uplink D 2 D transmit power of the first mobile terminal, a first maximum coverage area of a D2D signal of the first mobile terminal is estimated; and
a first transmission module configured to:
send, in response to a first determination that the uplink transmit power falls within a preset range that corresponds to a second maximum coverage area external to which the second mobile terminal is located, to at least one forwarding node whose distance from a base station is no greater than another distance of the first mobile terminal from the base station, indication information for instructing the at least one forwarding node to forward measured data of the first mobile terminal, wherein the indication information comprises a forwarding request for the measured data, the measured data, and a forwarding priority of the measured data, wherein the measured data comprises information associated with at least two elements selected from a moving speed of the first mobile terminal, a location of the first mobile terminal, a moving direction of the first mobile terminal, or a braking of the first mobile terminal, and wherein the preset range is determined by the first mobile terminal or the base station according to at least a transmission requirement of the measured data, a congestion level of a transmission channel, a geographical location of the first mobile terminal, and a density of other mobile terminals in a region in which the first mobile terminal is located, and
stop, in response to a second determination that the uplink transmit power does not fall within the preset range, sending the forwarding request to the at least one forwarding node, wherein the stop of the sending of the forwarding request comprises at least simultaneously sending the measured data to the at least one forwarding node.

9. The apparatus of claim 8 , wherein the executable modules further comprise:
a second transmission module configured to send the measured data in response to a third determination that a response to the forwarding request is received.

10. The apparatus of claim 9 , wherein the executable modules further comprise:
a second determining module configured to determine a resource configuration associated with the measured data, and
the first transmission module is configured to send the indication information to the at least one forwarding node according to the resource configuration.

11. The apparatus of claim 10 , wherein the second determining module comprises:
a transmission unit configured to send a resource configuration request to another base station of a cell to which the first mobile terminal attaches; and
a receiving unit configured to receive configuration information associated with the resource configuration.

12. The apparatus of claim 8 , wherein the first transmission module is configured to send the indication information to the at least one forwarding node by using at least a dedicated short range communications (DSRC) technology.
