Problems solved by technology

This is because, for the messages existing in the system, different users have different degrees of interest in different contents. Although the transmission delay is reduced, the messages received by the users may not be needed by the users at all. In this case, the corresponding The transmission process becomes an invalid transmission

Embodiment 1

[0058] Embodiment 1 of the present invention provides a transmission content scheduling method combined with user interests, such as figure 1 As shown, the method includes the following steps:

[0059] S100. Receive a first interest configuration file sent by a neighbor node and used to describe a user's interest in different messages.

[0060] The interest configuration file is a file that quantitatively describes the user's interest in different message contents. Preferably, each node pre-collects the user's degree of interest in different keywords and subject content, and generates its own interest configuration file.

[0061] S101. Calculate a first interest probability of a neighbor node for a first message to be transmitted in combination with a first interest configuration file.

[0062] S102. Receive a first future utility for receiving a first message to be transmitted in each time slot sent by a neighbor node.

[0063] The first future utility is obtained by quant...

Embodiment approach

[0070] Embodiment 2 of the present invention provides another embodiment of a transmission content scheduling method based on user interests. For ease of understanding, this embodiment is described from the perspective of interaction between two nodes. As an implementable mode, the method includes the following steps:

[0071] S200. Node B (ie, a neighbor node) sends a first interest configuration file to node A (ie, its own node).

[0072] S201. Node A receives a first interest configuration file, and calculates a first interest probability of node B for a first message to be transmitted in combination with the first interest configuration file.

[0073] S202. Node A sends the first interest probability to node B.

[0074] S203. Node B receives the first interest probability, calculates the first future utility based on the first interest probability, and sends it to node A.

[0075] S204. Node A receives the first future utility sent by each neighbor node, and sums the fut...

Embodiment 3

[0079] Embodiment 3 of the present invention provides a preferred embodiment of a transmission content scheduling method combined with user interests. In this embodiment, the method includes steps:

[0080] S300, each node generates its own interest configuration file.

[0081] S301. The own node receives the first interest configuration file sent by the neighbor node.

[0082] When a node receives content transmitted from a base station or other forwarders, it also becomes a forwarder. use Indicates the set of content owned by forwarder f in time slot τ, Indicates the set of neighbors of forwarder f in time slot τ. Each neighbor must explicitly report its own interest profile to forwarder f, mainly including the user's interest in different keywords. The forwarder f (that is, its own node) receives the interest configuration file sent by the neighbor node.

[0083] S302. The own node calculates a first interest probability of the neighbor node for the first message to ...

Abstract

The invention discloses a transmission content scheduling method, device and mobile terminal combined with user interests. The method comprises the steps of: receiving the first interest configuration file sent by the neighbor node; calculating the first interest probability in combination with the first interest configuration file; receiving the first future utility of receiving the first message to be transmitted in each time slot sent by the neighbor node , the first future utility is obtained by quantitative calculation based on the degree of interest of the user in the message to be transmitted; calculate the global utility of transmitting the first message to be transmitted; calculate the average global utility of each first message to be transmitted, and give priority to the transmission of the average global utility Larger first message to be transmitted. The device includes a first interest modeling unit, a utility calculation unit and a transmission scheduling unit. The mobile terminal includes a processor for executing the above method. The transmission content scheduling method, device and mobile terminal based on user interests provided by the present invention can schedule transmission content based on user interests, thereby improving user experience.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a transmission content scheduling method, device and mobile terminal based on user interests. Background technique [0002] With the rapid development of wireless communication technology and the rapid popularization of various portable devices and applications, the various needs of mobile users often trigger a large amount of data services in the cellular network. According to the latest research report, the global mobile data traffic will increase 7 times from 2016 to 2021, and it is estimated that the global mobile data traffic per month will reach 49 exabytes by 2021. The continuous growth of data traffic poses severe challenges to the carrying capacity of the current cellular network, causing severe loads on the base station, often causing problems such as poor service quality and inability to respond to services requested by users in a timely manner. ...
