Problems solved by technology

[0003] In the process of realizing the above, the inventors found that there are at least the following problems in the prior art: when transmitting data packets between the evolved base station and the relay node, it is necessary to consume more air interface resources to transmit non-valid data in the data packets, For example, the addressing identification in the identification area wastes more transmission resources and reduces the efficiency of transmission

Embodiment 1

[0027] In the embodiment of the present invention, the uplink transmission of data packets is taken as an example for illustration. The specific process is as follows: figure 2 Shown:

[0028] S201. The relay node receives user data;

[0029] In the embodiment of the present invention, the relay node allocates a unique channel for data transmission to a user, and records the user identification corresponding to the user who uses the channel to transmit data. When receiving the data, the relay node determines which user the data comes from according to the channel used in the data transmission process, and acquires the user identifier of the user.

[0030] Among them, before determining the user identity corresponding to the data through the channel for transmitting data, it also includes:

[0031] Record the user ID corresponding to each channel used to transmit data within the coverage of the relay node.

[0032] In the embodiment of the present invention, there is at lea...

Embodiment 2

[0043] In the embodiment of the present invention, the downlink transmission of data packets is taken as an example for illustration. The specific process is as follows: image 3 Shown:

[0044] S301. The relay node receives the data packet carrying the user's local identifier sent by the evolved base station;

[0045] The data packet is sent according to the mapping relationship between the user ID of the user within the coverage of the evolved base station and the local ID of the user within the local coverage;

[0046] In the embodiment of the present invention, all receiving methods in the prior art are applicable to this step, and details are not repeated here. The evolved base station sends a data packet carrying the user's local identifier, and the specific process is as follows:

[0047] The eNB obtains data sent to the user, and determines the user identifier of the user. According to the user ID, determine the user local ID corresponding to the user ID from the ma...

Embodiment 3

[0055] When the equipment of the mobile communication system starts up, the mapping relationship between the user ID of the user and the local ID of the user needs to be established between the relay node and the evolved base station. The mapping relationship may be set by the relay node or the eNB.

[0056] One is that the relay node sets the user mapping relationship and sends the set result to the evolved base station. The specific process is as follows:

[0057] The relay node obtains the coverage of the local signal, counts the total number of users within the coverage, and obtains the maximum value of the total number of users within a period of time. If the maximum value of the total number of users is less than 64, set the length of the user's local identification to 6 bits; if the maximum value of the total number of users is greater than or equal to 64 and less than 128, then set the length of the user's local identification to 7 bits; if the maximum number of users ...

Abstract

A method and apparatus for transmitting data package, relating to communication field, are invented for solving the problem in the prior art of excessive data quantity of unvalid information in data packages and wasting transmission source. The method includes: receiving user data;transmitting a first data package which carries a user local identifier and includes the user data according to the mapping relationship between a user identifier within the coverage area of the evolved node base station and a user local identifier within the local coverage area;or receiving a second data package which carries the user local identifier transmitted by the evolved node base station, wherein the second data package is transmitted according to the mapping relationship between a user identifier within the coverage area of the evolved node base station and the user local identifier within the local coverage area; transmitting the data in the second data package to the corresponding user according to the user local identifier in the second data package, in which the length of the user local identifier is less than the length of the user identifier. The technical scheme can be applied to transmit the data package.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data packet transmission method and device. Background technique [0002] In the mobile communication system, the evolved base station encapsulates the data sent to the user into a data packet, and adds an addressing identifier in the identification area of ​​the data packet, which is used to indicate which user the data in the data packet of the relay node belongs to. The data packet with the added identifier is sent to the relay node through the tunnel, and the relay node sends the data in the data packet to the corresponding user according to the addressing identifier in the data packet. For example, the addressing identifier added by the evolved base station in the identifier area of ​​the data packet is C-RNTI (Cell Radio Network Temporary Identity, cell radio network temporary identifier), and then the relay node receives the data packet carrying the C-RNTI identifier, a...
