Embodiment 1

[0081] Such as figure 1 Shown is a flow chart of a communication method through a mobile communication network provided by an embodiment of the present invention, and is described in detail as follows:

[0082] In step S101 , the MME acquires information about whether the devices of both communicating parties support D2D communication.

[0083] In the embodiment of the present invention, before the two communication devices communicate, the MME needs to obtain information about whether the two communication devices support D2D communication, and if yes, enter step S102, and if not, select the existing mobile communication system for communication. See figure 2 and to figure 2 description of.

[0084] In step S102, the MME judges whether the two communication devices have the same security algorithm.

[0085] In the embodiment of the present invention, each piece of equipment may have different security algorithms, if they have the same security algorithm, go to step S103...

Embodiment 2

[0151] Such as figure 2 Shown is an embodiment of the invention figure 1 The specific implementation flow chart of step S101 shown is described in detail as follows:

[0152] In step S201, the calling party UE self-tests whether it supports D2D communication, and if it supports D2D communication, the calling party UE initiates a D2D communication request to the MME.

[0153] In step S202, the MME receives the communication request and the information supporting D2D communication sent by the calling UE, and carries an instruction to detect whether D2D communication is supported when calling the called UE.

[0154] In step S203, the called UE receives the communication call from the MME, self-tests whether it supports D2D communication according to the detection instruction, and sends the detection result to the MME.

[0155] In the embodiment of the present invention, the MME in the mobile communication technology detects both calling and called UEs. When the MME calls the c...

Embodiment 3

[0157] Such as image 3 Shown is a flow chart of a communication method through a mobile communication network provided by another embodiment of the present invention, and the method includes the following steps:

[0158] In step S301, information on whether the calling party UE and the called party UE support D2D communication is obtained.

[0159] In the embodiment of the present invention, before the two communication devices communicate, the MME needs to obtain information about whether the two communication devices support D2D communication. If they support it, go to step S302. If not, choose the existing mobile communication system for communication. The specific steps are:

[0160] S1. The calling party UE self-tests whether it supports D2D communication, and if D2D communication is supported, the calling party UE initiates a D2D communication request to the MME;

[0161] S2. Receive the communication request sent by the calling party UE and the information supporting...

Abstract

The invention is applied to the field of communication and provides a method for communication through a mobile communication network. The method comprises the following steps that mobility management entity (MME) sends communication materials to equipment of two communication parties; evolved Node B (eNB) indicates that the equipment of the two communication parties establishes communication data carriers, generates radio network temporary identity (RNTI), and distributes the RNTI to the equipment of the two communication parties; the equipment of the two communication parties performs communication according to received communication materials by using existing mobile communication network. By means of the embodiment of the method for communication through the mobile communication network, MME acquires information that whether UE (user equipment) can perform D2D (disk to disk) communication, then whether two communication parties can perform identical security algorithm is judged, security algorithm used by existing mobile communication is sent to the two communication parties, and the two communication parties are in communication through the security algorithm used by existing mobile communication technology, so that the mobile communication technology is applied in D2D communication aspect, and by means of the existing mobile communication technology, the verification process is simple, and security level is high.
