Description

Method for establishing X2 link, EMS, base station and storage medium
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a method for establishing an X2 link, an EMS, a base station and a computer readable storage medium.
Background
SA (standard alone) refers to a newly established 5G network, including a new base station, a backhaul link, and a core network. While introducing brand new network elements and interfaces, the SA also adopts new technologies such as network virtualization, software defined networking and the like in a large scale and is combined with the 5G NR, and meanwhile, the technical challenges of protocol development, network planning deployment and intercommunication interoperation of the SA exceed those of 3G and 4G systems.
NSA (Non-standard one, Non-independent networking) refers to deployment of 5G networks using existing 4G infrastructure. The 5G carrier based on the NSA architecture carries only user data, and its control signaling is still transmitted through the 4G network. The operator can determine the upgrade site and area according to the service requirements, and does not necessarily need complete one-piece coverage. Because the 5G carrier wave is tightly combined with the 4G system, the service continuity between the 5G carrier wave and the 4G carrier wave is ensured. Under the condition that the 5G network coverage is not complete, the NSA architecture is beneficial to ensuring the good experience of the user.
The X2 interface is an interface between base stations that supports direct transfer of data and signaling. The base stations are linked with each other through an X2 interface to form a mesh network for transmitting data. Because there is no signaling link between the gbb (5G base station) and the core network side during NSA networking, the 4G/5G base station cannot acquire an IP (Internet Protocol) address, and thus cannot establish an X2 link.

To better illustrate the process of establishing the X2 link in different application scenarios, the following description is provided in conjunction with fig. 8-10:
as shown in fig. 8, the first base station is an evolved Node B (eNB), and the second base station is a gNB. The 4G and 4G network elements belong to the same EPC (Evolved Packet Core, 4G Core network), and the 5G base station has no independent Core network.
The eNB initiates a request for acquiring IP address information of the gNB, which is specifically as follows:
step a: the eNB carries the IP address and the ID of the eNB to request the IP address information of the gNB, sends the request message to a 4G EMS (Element Management System), and initiates a request for acquiring the IP address information of the gNB;
step b: after receiving the request, the 4G EMS constructs a message and sends the message to the 5G EMS;
step c: after receiving the message, the 5G EMS analyzes the ID of the gNB, sends the IP address and the ID of the eNB to the gNB and initiates a request for acquiring the IP address information of the gNB;
step d: after receiving the IP address and the ID of the eNB sent by the 5G EMS, the gNB establishes a link with the eNB and returns the IP address and the ID of the gNB to the 5G EMS;
step e-step f: after receiving the message returned by the gNB, the 5G EMS returns the IP address and the ID of the gNB to the 4G EMS; the 4G EMS sends the IP address and the ID of the gNB to the corresponding eNB;
step g: the eNB can complete the addition of the X2 link after receiving the IP address and ID of the gNB.
As shown in fig. 9, both the first base station and the second base station are the gbb. The first base station gNB1 initiates a request for acquiring the IP address information of the second base station gNB2, which is specifically as follows:
step a 1: the gNB1 carries the IP address and ID of the gNB1, requests the IP address and ID of the gNB2, and sends the request message to the 5G EMS;
step b 1: after receiving the request message, the 5G EMS sends the IP address and the ID of the gNB1 to the gNB2 and initiates a request for acquiring the IP address information of the gNB 2;
step c 1: after receiving the message sent by the 5G EMS, the gNB 2: if the X2 policy switch is turned on, the gNB2 detects that the network is intercommunicated with the IP address of the gNB1 and the number of the X2 of the gNB2 does not exceed the limit number, an X2 link with the gNB1 is established, and the IP address and the ID of the gNB2 are returned to the 5G EMS; if the X2 policy switch is turned off, or the network between the gNB1 and the gNB2 is not intercommunicated, or the number of X2 of the gNB2 exceeds the limit, the gNB2 does not establish an X2 link with the gNB1 and does not return a message to the 5G EMS;
step d 1: after receiving the message of gNB2, the 5G EMS analyzes the ID of gNB1 and sends the IP address and ID of gNB2 to gNB 1;
step e 1: after receiving the message of the 5G EMS, the gNB1 analyzes the IP address of the gNB2 and establishes an X2 link with the gNB 2.
As shown in fig. 10, the first base station gNB1 and the second base station gNB2 are different vendors. The first base station gNB1 initiates a request for acquiring the IP address information of the second base station gNB2, which is specifically as follows:
step a 2: the gNB1 carries the IP address and ID of the gNB1, requests the IP address and ID of the second base station gNB2, and sends a request message to the 5G EMS;
step b 2: after receiving the request message, the 5G EMS inquires the IP address and the ID of the second base station gNB2 from the registration table of the heterogeneous manufacturer base station, and sends the inquired information to the gNB 1;
step c 2: and the gNB1 receives the message sent by the 5G EMS and completes the establishment of the X2 link with the second base station gNB 2.
As shown in fig. 11, in an SA scenario, the eNB base station and the gNB base station belong to different core networks, and the eNB base station and the gNB base station may also obtain IP address information between the eNB and the eNB, between the eNB and the gNB, and between the gNB and the inter-vendor base station through an EMS in an NSA scenario, and establish an X2 link. The specific implementation steps are similar to those described above and are not described herein again.
