There are two deployment options for 5G NR, SA and NSA. Currently, for EN-DC (E-UTRA-NR dual connectivity) links under NSA networking, semi-manual configuration is generally adopted, and a link on the LTE base station side needs to be manually configured. Therefore, how to implement EN-DC link self-establishment is a technical problem that needs to be solved currently.
In order to solve the technical problems, the embodiment of the invention provides a link self-establishment method, a device, electronic equipment and a storage medium, so as to realize EN-DC self-establishment under NSA networking.
The following is a description of specific examples.
Fig. 1 is a flowchart of a link self-establishment method according to an embodiment of the present invention, where the link self-establishment method may be used for a first LTE network element, for example: a first eNodeB (Evolved Node B, LTE base station); as shown in fig. 1, the link self-establishment method may include the steps of:
s101, determining a network element identification of a target network element, wherein the target network element is used for representing the network element which needs to establish a link with a first LTE network element.
Specifically, the target network element may be an NR network element, such as: 5G RAN (Radio Access Network ) base station (i.e., gNodeB); a second LTE network element may also be used, such as: and a second eNodeB.
S102, determining whether to acquire transmission network layer TNL (Transport Network Layer, transmission network layer) information corresponding to the network element identification through an OMC network element according to an OMC configuration strategy set by the OMC (Operation and Maintenance Center, operation maintenance center) network element.
In particular, OMC network elements may be used to store configuration data for the whole network under NSA networking. And, the OMC configuration policy set by the OMC network element may include the first configuration information and/or the second configuration information.
Wherein the first configuration information is used to indicate a priority of each device comprising an OMC network element and an MME (Mobility Management Entity ) for providing TNL information. Such as: the OMC network elements have a higher priority than the MME.
The second configuration information is used to indicate OMC query channels for TNL information. Such as: OMC query channels may include IP (Internet Protocol, internetworking protocol) addresses, ports, communication means; the TNL information may be traffic IP information of the target network element.
S103, if yes, the network element identification is sent to an OMC network element; when TNL information corresponding to the network element identification returned by the OMC network element is received, a link between the OMC network element and the target network element is established according to the TNL information corresponding to the network element identification.
Specifically, the first LTE network element sends the network element identifier to the OMC network element, so as to obtain TNL information corresponding to the network element identifier, that is, TNL information of the target network element, from the OMC network element.
The first LTE network element may include, when establishing a link with the target network element:
1.1, the first LTE network element uses a source IP as a service IP of the first LTE network element, a destination IP as an IP of the target network element, a port number is 36412 of EN-DC port number specified by 3GPP, and an EN-DC link SCTP (Stream Control Transmission Protocol, flow control transmission protocol) and an AP (Access Point) are created.
1.2, the first LTE network element may send an SCTP INIT (initialization) message to the target network element, where an IP address parameter (address parameter) of the SCTP INIT message carries an IP of the first LTE network element.
1.3, the target network element extracts the IP of the first LTE network element from the SCTP INIT message, uses the source IP as the service IP of the target network element, uses the target IP as the IP of the first LTE network element, uses the port number as the EN-DC port number 36412 specified by 3GPP, and creates EN-DC SCTP and AP locally.
1.4, the first LTE network element and the target network element complete EN-DC self-establishment through four handshakes of SCTP.
In an exemplary scenario, as shown in fig. 2, the eNodeB21 is a first LTE network element and the eNodeB/gNodeB22 is a target network element. The eNodeB21, when establishing a link between the eNodeB21 and the eNodeB/gNodeB22, may include:
2.1, eNodeB21 determines the network element identification of eNodeB/gNodeB 22;
2.2, the eNodeB21 determines whether TNL information of the eNodeB/gNodeB22 is acquired through the OMC network element 23 according to an OMC configuration strategy preset by the OMC network element 23; such as: if the priority of the OMC network element 23 is higher than the priority of the MME24, i.e. the OMC network element 23 is prioritized, the TNL information of the eNodeB/gNodeB22 may be obtained by the OMC network element 23; if the priority of OMC network element 23 is lower than the priority of MME24, i.e. MME24 takes precedence, the TNL information of eNodeB/gmodeb 22 may be acquired by MME24.
2.3, if the eNodeB21 determines that the TNL information corresponding to the network element identifier is obtained through the OMC network element 23, the network element identifier is sent to the OMC network element 23.
2.4, if the eNodeB21 receives the TNL information corresponding to the network element identifier returned by the OMC network element 23, according to the TNL information corresponding to the network element identifier, the source IP is the service IP of the eNodeB21, the destination IP is the IP of the eNodeB/gNodeB22, the port number is 36412 of EN-DC port number specified by 3GPP, and an EN-DC link SCTP and AP are created.
2.5, eNodeB21 may send an SCTP INIT message to eNodeB/gNodeB22, the IP address parameter of the SCTP INIT message carrying the IP of eNodeB 21.
2.6, the eNodeB/gNodeB22 extracts the IP of the eNodeB21 from the SCTP INIT message, takes the source IP as the service IP of the eNodeB/gNodeB22, takes the IP of the eNodeB21 as the destination IP, takes the EN-DC port number 36412 specified by 3GPP as the port number, and creates the EN-DC SCTP and the AP locally.
2.7, eNodeB21 and eNodeB/gNodeB22 complete EN-DC self-establishment by four handshakes of SCTP.
It can be seen from the above embodiments that, by determining the network element identifier of the target network element, the target network element is used for characterizing the network element that needs to establish a link with the first LTE network element, according to the OMC configuration policy set by the OMC network element, it is determined whether to obtain the TNL information of the transport network layer corresponding to the network element identifier through the OMC network element, if yes, the network element identifier is sent to the OMC network element, and when the TNL information corresponding to the network element identifier returned by the OMC network element is received, a link between the network element and the target network element is established according to the TNL information corresponding to the network element identifier, thereby implementing that the EN-DC self-establishment is completed by obtaining the TNL information through the OMC network element, and improving the flexibility of the link self-establishment.
Further, based on the above method, in S101 above:

and if the target network element is the second LTE network element, the link between the first LTE network element and the second LTE network element is an X2 link.
The embodiment can be seen that the X2/EN-DC self-establishment and fusion are completed by acquiring TNL information through the OMC network element, so that the universality of the link self-establishment is improved.
Further, on the basis of the method, the target network element is an NR network element; in performing S101, it may include:
s1011, according to the ANR (Automatic Neighbor Relation ), obtaining NCGI (NR Cell Global Identifier, NR cell global identification) information of the NR network element.
Specifically, the first LTE network element may obtain the NCGI information of the NR network element through an EN-DC ANR procedure.
Among other things, the ANR function in the EN-DC ANR process is responsible for managing and maintaining a table called a conceptual neighbor relation table, NRT (Conceptual NeighbourReleation). Also, in ANR, the neighbor detection function discovers new neighbor cells and adds them to the NRT.
S1012, determining the network element identification of the NR network element according to the NCGI information.
As can be seen from the above embodiments, when determining the network element identifier of the target network element, the network element identifier may be determined according to ANR, so as to implement linkage with the EN-DC ANR process, and further complete SON (Self-Organizing Network ) automation.
Further, on the basis of the above method, the OMC configuration policy includes: the first configuration information and/or the second configuration information; the first configuration information is used for indicating the priority of each device, and each device comprises an OMC network element and a Mobility Management Entity (MME) for providing TNL information; the second configuration information is used for indicating an OMC query channel of TNL information; in performing S102, it may include:
s1021, if the priority of the OMC network element is determined to be greater than the priority of the MME according to the first configuration information, detecting an OMC link state according to the second configuration information. The OMC link state may be the link state of OMC network element 23 in fig. 2.
Specifically, if the first configuration information includes the priority of the OMC network element, the priority of the OMC network element is indicated to be greater than the priority of the MME; and if the first configuration information comprises the priority of the MME network element, indicating that the priority of the MME is greater than the priority of the OMC network element.
The OMC link state may be specifically: whether the OMC is online, whether the OMC queries for channels available, etc.
And S1022, if the OMC link state is in an available state, determining to acquire the TNL information through the OMC network element.
Specifically, the OMC link state being in an available state may indicate that the OMC is online and that OMC query channels are available.
In addition, if the priority of the OMC network element is determined to be smaller than the priority of the MME according to the first configuration information, detecting an MME link state according to the second configuration information, and if the MME link state is in an available state, determining to acquire the TNL information through the MME. The MME link state may be the link state of MME24 in fig. 2.
Specifically, the MME link state may be specifically: whether the MME is on-line, whether a link between the MME and the first LTE network element is available, etc.
Further, on the basis of the above method, when the network element identifier is sent to the OMC network element in S103, the method may include:
