All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the prior art, since the 3GPP protocol can only carry Global RAN Node ID information in the process of establishing the NG interface and the Xn interface, when different operators share a base station, the establishment processes of the NG interface and the Xn interface can only be performed separately, which may cause the following effects:

increasing signaling interaction process of NG interface;

adding an Xn interface signaling interaction process;

increasing the load of the tracking tool;

increasing transmission resources and increasing the memory overhead of the device.

In order to reduce the 5G network establishment cost and improve the utilization rate of wireless resources of the 5G network in the 5G system, network sharing is an effective technical means for different operators in part of regions. The network sharing is divided into two modes of wireless network sharing and core network roaming, and the embodiment of the application mainly aims to solve the problem that in a wireless network sharing environment, different operators plan different base station identifiers (gNBid) based on the same physical base station according to respective plans, and the NG interface and Xn interface establishment processes of each public land mobile network (per PLMN) are triggered respectively. After optimization, multiple NG interface and Xn interface establishing processes, particularly the Xn interface, are not needed.

Therefore, the embodiment of the application provides an information transmission method and an information transmission device, which are used for reducing signaling interaction processes of an NG interface and an Xn interface and reducing interface signaling overhead.

It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.

The embodiment of the application provides an optimization scheme for wireless network sharing. The wireless network sharing refers to that a plurality of operators share a wireless network part and share wireless resources, and a core network may share or establish a core network of each operator, including an independent network manager or a shared network manager. In a 5G network, the length of gNBid ranges from 22 bits to 32bits, and the values of operators may be different according to respective network plans. For the shared base station, each operator configures different gNBid based on a respective Public Land Mobile Network (PLMN), and establishes respective NG interface connections (which may be the same or different) with core Network Access and Mobility Management Function (AMF) entities. And different Xn interface connections are established between the shared base stations based on different gNBids. However, in the current 3GPP protocol NG SETUP (NG SETUP) and Xn SETUP (Xn SETUP), only one gNBid information can be carried, and multiple gnbids cannot be carried in one SETUP process, so that the NG interface and the Xn interface must be separately established when the wireless network is shared.

In the embodiment of the present application, a 3GPP protocol needs to be optimized, Information Element (IE) information carried in signaling interaction processes between an NG interface and an Xn interface in the optimized protocol is optimized to carry a Global radio access network Node ID list (Global RAN Node ID list) by carrying only one Global RAN Node ID, and the optimized signaling interaction process includes but is not limited to: NG interface establishment REQUEST (NG SETUP REQUEST), NG interface establishment RESPONSE (NG SETUP RESPONSE), Xn interface establishment REQUEST (Xn SETUP REQUEST), Xn interface establishment RESPONSE (Xn SETUP RESPONSE), configuration update process, etc., thereby solving the existing problem through the optimization of the shared base station.

The technical scheme provided by the embodiment of the application comprises the following steps:

optimizing an existing NG interface and an Xn interface protocol (the version of the existing protocol is release15), and optimizing a Global radio access network Node identifier (Global RAN Node ID) to a Global radio access network Node identifier list (Global RAN Node ID list) and a new air interface cell Global identifier (NR CGI) to a new air interface cell Global identifier list (NR CGI list).

Each operator configures respective IP address according to own planning, and completes the interface establishment of each base station identifier (each gNBid per PLMN) in each PLMN in the process of one interface establishment.

If the parameters and cell information related to the Transport Network Layer (TNL) are required to be dynamically added, and/or deleted, and/or modified, the parameters can be adjusted by different operators at one time through a configuration updating process.

Different operators commonly deploy core networks or respectively deploy core networks independently, and access and management function area identifiers (AMF regions IDs) carried in signaling messages in the signaling interaction process are kept consistent with a Global radio access network Node identifier list (Global RAN Node ID list) and/or a new air interface cell Global identifier list (NR CGI list), so that the successful signaling interaction is ensured.

The scheme provided by the embodiment of the application influences the existing realization of the NG interface, the Xn interface part signaling message content and the base station sharing characteristic, and is the optimization of the existing 3GPP protocol and different operators based on the base station identification wireless network sharing application scene planned by the operators respectively.

In summary, referring to fig. 1, the information transmission method before optimization includes:

step 1, different operators share the base station, and respectively plan respective base station identifiers (gNBid), Cell identifiers (Cell id), PLMN and the like.

And 2, executing processes such as NG interface establishment (NG SETUP), Xn interface establishment (XN SETUP), configuration updating and the like.

Step 3, judging whether gNBids configured by each operator for the shared base station are the same, if so, executing step 4; otherwise, step 5 is executed.

And 4, performing traditional Radio Access Network (RAN) sharing (sharing).

And 5, executing signaling interaction process of the NG interface and/or the Xn interface, wherein only one gNBid is carried.
