Embodiment Construction

[0049] Data transmission between base stations is carried out through the IuNB interface between the base stations; as shown in Figure 1, the IuNB interface is located between two base station nodes to provide bidirectional data and control signaling transmission; the protocol stack of the IuNB interface is shown in the figure As shown in 2, the data transmission between the base stations is data transmission based on the frame protocol, that is, data transmission is realized between the base stations through the transmission of data frames.

[0050] The data frames of the IuNB interface are used to transfer user data sent from one NB to another NB. According to whether user data is sent or received on the Uu interface, data transmission on the IuNB interface can be divided into two directions: uplink and downlink. In the uplink direction, the source NB transmits the user data received from the Uu interface to the target NB in ​​the form of an IuNB interface data frame, and th...

Abstract

The method includes following steps. When a source base station needs to send data frames to a target base station, first, the transmission synchronization between the source base station and the target base station is realized by transmitting a control frame. Then, the transmission of data frames is carried out between the source base station and the target base station, and the transmission time is adjusted based on the need. The procedure of monitoring whether the transmission carrier is in normal operation state is also carried out in the transmission synchronization process. The invention realizes the transmission of data frames between base stations by using the interface between base stations, providing the function of synchronization and receive control for the transmission procedure. Thus, the reliability of data transmission is ensured.

Description

technical field [0001] The invention relates to wireless network transmission technology, in particular to a method for realizing data transmission between base stations based on frame protocol. Background technique [0002] With the development of wireless network technology and services, the wireless interface technology suitable for high-speed data communication in the future will be more and more self-adaptive, and the time requirement for wireless network signaling processing will be further shortened. Therefore, the base station will terminate more and more signaling closely related to the physical layer of the radio interface and processes related to control and service transmission, and undertake part of the radio resource management function separated from the RNC (Radio Network Controller). [0003] At the same time, with the development of network transmission technology based on IP (Internet Protocol), IP transmission technology has also been introduced into the ...
