Problems solved by technology

[0009] 2. There is no direct communication connection between the RN and the core network, and the data of the users served by the RN needs to be transferred through the donor eNB when it is transmitted between the RN and the core network;
[0010] 3. There is no direct communication connection between the two RNs, and the interaction between RNs needs to be transferred through the RN's donor eNB
When the content of the multiple messages that the RN needs to send is completely or partially the same, the multiple messages need to be sent to the donor eNB one by one. The same message content is transmitted multiple times on the backhaul link, resulting in the backhaul link waste of resources
Not only does the above-mentioned waste of air interface resources exist between RN and eNB, but also there is a waste of air interface resources between other nodes in the wireless network that have a forwarding relationship.

Embodiment 1

[0072] In this embodiment, the message format adopted by the interface combination message is as follows:

[0073] composite message ID

message content part

Number of target nodes

target node address list

[0074] In the above message format, the specific meanings of each field are as follows:

[0075] a. Combined message identifier. The transit node knows through the combined message ID that it needs to perform special processing on the message, that is, it needs to forward the message content part according to the target node address list; the combined message ID can be explicitly indicated, for example, in the interface combined message, define a Bit (bit), if the bit is 0, it means an interface common message, and if it is 1, it means an interface combination message; the combination message identifier can also be implicitly indicated, such as defining a communication channel between a source node and a transit node for Specially transmit inte...

Embodiment 2

[0097] In this embodiment, the message format adopted by the interface combination message is as follows:

[0098] Number of target nodes

message content part

target node address list

[0099] The difference between this message format and the message format in Embodiment 1 is that this message format omits the combination message identification field, and the X2 interface ordinary message is regarded as the X2 interface combination message when the target node address list only contains one target node. As a special case, therefore, only one above-mentioned X2 interface message needs to be defined, and the meanings of the target node number, message content and target node address list can be referred to the description in the first embodiment.

[0100] In this embodiment, the processing flow of the source node is as follows:

[0101] Step S21: the source node generates an X2 interface message;

[0102] Step S22: judging whether the generated X2 inte...

Embodiment 3

[0141]In this embodiment, the source node sends the other extracted data content to the transit node through the wireless interface through the interface combination message carrying the same extracted data content and the address information of the target node of the N messages, that is The interface combination message carries the same data content in the N messages at the same time, and also carries different data content, and the same data content only appears once in the interface combination message. The message formats that can be used are as follows:

[0142]

[0143] In the above message format, the specific meanings of each field are as follows:

[0144] a. Number of target nodes. This field is used to indicate the number of target node address information contained in the target node address list, and is an optional field;

[0145] b. Public information section. This part carries the same data content extracted in step 71;

[0146] c. Address information of t...

Abstract

The embodiment of the invention discloses a method for information interaction between nodes, comprising the following steps: a source node determines that the current N messages to be sent carry the same data content, then extracts the same data content from the N messages, and sends the extracted same data content to a transit node through a wireless interface, wherein sending times are less than N; or the source node generates the messages to be sent, determines the messages to be sent need to be sent to N target nodes, and then sends the messages to be sent to the transit node through the wireless interface, wherein the sending times are less than N. The embodiment of the invention further discloses a system and equipment for information interaction between the nodes. The invention can effectively save the air interface resource between the source node and the transit node.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, system and equipment for information interaction between nodes. Background technique [0002] The network structure of the Long Term Evolution (LTE) system is as follows: figure 1 shown. Nodes of the core network include Mobility Management Entity (MME) and Serving Gateway (S-GW), etc., and nodes of the access network only have one type of base station (eNB). There may be an X2 interface between two eNBs. [0003] The X2 interface is used to forward radio resource management (Radio Resource Managerment, RRM) signaling and user data between eNBs. For example, inter-cell interference coordination (Inter-cell Interference Coordination, ICIC) messages between different eNBs are transmitted through the X2 interface of. [0004] The MME mainly implements functions such as authentication and mobility management, and the S-GW mainly implements routing and trans...
