Embodiment 1
[0234] Embodiment 1. The proximity communication implementation method provided by this embodiment includes: a relay request process and a relay path establishment process;
[0235] 1. For the relay request process initiated by the communication initiator to a communication device that is adjacent to itself and supports relay capabilities, see Figure 10 shown, including the following steps:
[0236] Step 101, the communication initiator sends a relay request message to a communication device that is adjacent to itself and supports relay capability, and the parameter carried in the message is the identification information of the communication target party;
[0237] Step 102. After receiving the relay request message, the communication device judges whether it can serve as a relay node between the communication initiator and the communication target, and returns a relay reply message to the communication initiator; specifically:
[0238] If the communication device determines...
Embodiment 2
[0260] Embodiment 2. This embodiment is an optimization of Embodiment 1. When there are multiple third-party devices adjacent to the communication initiator and supporting the relay capability, the method of this embodiment may be adopted.
[0261]In this embodiment, the communication initiator searches for a communication device that supports the relay capability in the locally stored information of the communication devices that are adjacent to itself, and then the communication initiator, based on the received communication that is adjacent to itself and supports the relay capability, The strength of the signal strength of the device forms a priority list, which is composed of the identification information of the above-mentioned communication devices that are adjacent to the communication initiator and support relay capabilities, wherein the stronger the signal strength received by the communication initiator , the higher the priority of the identification information of th...
Embodiment 3
[0279] Embodiment 3. This embodiment is also an optimization of Embodiment 1. When there are multiple communication devices that are adjacent to the communication initiator and support relay capabilities, the method of this embodiment may also be used.
[0280] In this embodiment, the communication initiator searches for a communication device that supports the relay capability from the locally stored information of the communication devices that are adjacent to itself, and then initiates the communication to each communication device that is adjacent to itself and supports the relay capability. In the relay request process, among the communication devices that support the relay capability, the communication devices that can serve as the relay nodes between themselves and the communication target party (that is, the communication devices that return the relay reply message with the parameter Yes);
[0281] The communication initiator forms a priority list according to the recei...

Abstract
Disclosed are a method and an apparatus for implementing adjacent communication, used for performing communication by using a third-party device that can function as a relay node between a communication initiator and a communication target when the communication initiator is not adjacent to the communication target. The method in an embodiment of the present application comprises: after determining that a communication initiator is not adjacent to a communication target, the communication initiator sending a relay path establishment request to a third-party device that can function as a relay node between the communication initiator and the communication target, the relay path establishment request being used for initiating an establishment process of a first communication path between the third-party device and the communication target, and the relay path establishment request at least carrying identifier information of the communication target and a path parameter corresponding to the first communication path; and after determining that the first communication path is established successfully and determining a second communication path established between the communication initiator and the third-party device, the communication initiator communicating with communication target by using the established first communication path and second communication path.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for realizing proximity communication. Background technique [0002] In the current communication process between two user equipments (User Equipment, UE) defined in the 3rd Generation Partnership Project (3GPP), the data transmitted between the communication parties needs to be routed through the core network. figure 1 The data channel for communication between UE1 and UE2 is given when the serving gateway (Serving Gateway, SGW) and packet data gateway (Packet Data Network Gateway, PDN GW) of UE1 and UE2 are the same. [0003] If the above-mentioned communication method is also used when transmitting data between two user equipments that are very close to each other, the communication delay will be very large, and more network resources will be occupied. Therefore, 3GPP is currently studying the communication technology between adjacent devices...
