technical field

The present application relates to the technical field of wireless communication, and in particular to an XN interface interaction method and system.

Background technique

The network interface between the NG-RAN (NG Radio Access Network, NG wireless access network) nodes (gNB or ng-eNB) of the 5G (5th Generation Mobile Communication Technology) base station is called XN Interface, the XN interface supports the exchange of signaling information between two gNBs, and the forwarding of PDUs (Protocol Data Unit, protocol data unit) to each tunnel endpoint, and the gNBs exchange their respective base station global information and services through the XN interface signaling Cell information and neighbor cell information are used to implement load balancing, cell energy saving, energy saving cell activation, neighbor PCI (Physical Cell Identifier, physical cell identifier) conflict and confusion detection, etc.

When an XN interface is established between two base station nodes, and one of the serving cells of the current base station is blocked due to energy saving, the base station notifies the adjacent base station at the opposite end of the XN link by triggering the NG-RAN node Configuration Update process, so that the adjacent base station can The serving cell status of the current base station performs operations such as mobility management, load balancing, and energy-saving cell activation. When the serving cell load of the adjacent base station is too high, according to the existing protocol, the adjacent base station sends a cell activation request to the current base station through the XN link. The serving cells of the lower and adjacent base stations belong to the same coverage or part of the same coverage and are blocked due to energy saving, so as to share part of the load.

In the above protocol, the XNSetup Request message and the XN Setup Response message in the XN link establishment process between base stations lack cell status information, so before the XN link is established between base stations, the blocked cells under the current base station are not Known by the adjacent base station, the adjacent base station cannot activate the corresponding serving cell and cannot be used for functions such as load balancing; at the same time, according to the existing protocol framework, the current base station can only trigger the NG-RAN node once after the XN link is established. The Configuration Update process notifies the adjacent base station at the opposite end of the XN link that there is a service cell in a blocked state under the current base station, which increases network overhead and reduces network operation efficiency.

It should be noted that this application is mainly aimed at the method of XN link interaction between 5G base station systems in the 5G communication network, and optimizes the process of XN link interaction, so as to rely on the energy-saving function and switching function of the XN link. Provides convenience, and improves the efficiency and success rate of energy saving and switching.

First, the gNB base station distinguishes and saves the status of the serving cell, which is usually divided into normal availability, blocking due to energy saving, and blocking due to other reasons. When a gNB base station establishes an XN link with an adjacent gNB base station, the XN link establishment request and the XN link establishment response , the status of the serving cell (including the "normally available" state and the "blocked due to energy saving" state) is carried in the serving cell list;

When the gNB base station receives an XN link establishment request or an XN link establishment response, it saves the status of the serving cell in the message, and refers to the cell status in subsequent functions such as cell energy saving and load balancing;

When the status of the serving cell in the gNB base station changes, the gNB base station initiates the NG-RAN node Configuration Update process to notify the adjacent gNB base station. For the cell whose status changes, the status change includes but is not limited to the normal available state and the blocked state due to energy saving The transition between the normally available state and the blocked state for other reasons, and the transition between the blocked state due to energy saving and the blocked state for other reasons.

Assume that after the current base station is powered on, the current serving cell is established, including several serving cells, and any serving cell enters another blocking state due to a hardware device failure. The rest of the cells are in normal state;

After the adjacent base station of the current base station is powered on, the service cell to which it belongs, including several service cells, will be established. The adjacent base station will initiate the XN Setup process with the current base station; after the current base station receives the XN Setup process, it will return to the adjacent base station.

The adjacent cell saves the status information of any serving cell in the current serving cell, and if any serving cell in the serving cell to which the adjacent cell belongs needs to offload terminal load in the cell, any An offload terminal in a serving cell switches to any serving cell in the current serving cell.

Optionally, after the failure of any serving cell in other blocked states under the current base station is repaired and enters the normal available state, the current base station will initiate the NG-RAN node Configuration Update process, carrying the state information of the new available cell;

The adjacent base station saves the status information of the new available cell of the current base station according to the above-mentioned NG-RAN node Configuration Update process, and uses the available cell as a handover target candidate adjacent cell in the subsequent terminal management process. When the load of the serving cell is too high, the adjacent base station will switch some terminals under any serving cell to a new available cell in the current base station, reducing the wireless load capacity of the serving cell.
