Description

Method and device for establishing and updating base station link

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a method and a device for establishing and updating a base station link.

Background

With the maturity of the 5G technology, each operator and equipment vendor are establishing a 5G network nationwide, the initial stage of the 5G network is mainly an NSA (Non Stand Alone) networking, the NSA and LTE (Long Term Evolution) are covered simultaneously, a user realizes Dual connection, the experienced rate can reach at least several hundred Mbps/s, with the maturity of the 5G SA (Stand Alone) technology, the joint between manufacturers is also spreading as well as fiery, in the following, in order to better utilize the existing resources, for the initial stage of the SA network construction, there will be a lot of networking environments where NSA and SA cells are co-located, for the link connection between base stations, the links between different cells are different, for the links between NSA cells and LTE cells are endec (E-UTRA-NR Dual Connectivity, E-UTRA (Evolved-UMTS Radio Access, an evolved UMTS (Universal Mobile Telecommunications System ) terrestrial Radio Access) to NR (New Radio) link, and for a link between SA cells, an XN (Network interface between NG-RAN (Next Generation Radio Access Network) nodes) link of 38.423 is used.

For a conventional 4G Network, when establishing X2 of 36.423 and updating X2 configuration between base stations, it is not necessary to perform judgment, and only all activated cell information (such as frequency point, PLMN (Public Land Mobile Network), TAC (Tracking Area Code), and the like) in a station is transmitted to an opposite-end base station through a corresponding message, or networking of 4G and NSA is performed, and all activated cell information (such as frequency point, PLMN, TAC, and the like) in the station is also transmitted to the opposite-end base station through a corresponding message between base stations, and the opposite-end base station updates the cell information having a neighboring cell relationship to a configuration file, and simultaneously stores other cell information to a base station database for subsequent scenarios such as automatic neighboring cell addition. However, when the SA and NSA cells are co-sited, if the establishment or configuration update of the endec link is performed and the information of all cells in the station is still fed back to the opposite base station by using the original method, it may happen that the eNB (evolved Node B ) receives information of many SA cells, which has no meaning to the eNB base station, and the eNB also needs to store the information of the SA cells, and when a terminal reports a corresponding frequency point, the base station may not perform neighbor cell addition, which increases the complexity of the eNB implementation, and similarly, if the establishment or configuration update of the XN link is performed, for the SA cell, it may happen that the gNB (5G Node) base station receives information of many NSA cells, which needs to be stored but has no subsequent application scenario.

In summary, when a 5G system SA and NSA share a station and an LTE station to perform network deployment in a same coverage scenario, a method for establishing and updating a configuration between base stations is needed.
