Currently, semi-manual configuration is generally adopted for an EN-DC (E-UTRA-NR dual connectivity) link under NSA networking, and a link on an LTE base station side needs to be configured manually. Therefore, how to realize the EN-DC link self-establishment is a technical problem to be solved currently.
In order to solve the above technical problem, embodiments of the present invention provide a link self-establishment method, apparatus, electronic device, and storage medium, so as to implement EN-DC self-establishment under NSA networking.
The following description will be made by way 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 in 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 following steps:
s101, determining a network element identifier of a target network element, wherein the target network element is used for representing a network element needing to establish a link with a first LTE network element.
Specifically, the target network element may be an NR network element, such as: a 5G RAN (Radio Access Network ) base station (i.e., a gbodeb); it may also be a second LTE network element, such as: a second eNodeB.
S102, determining whether to acquire, by an OMC (Operation and Maintenance Center), Transport Network Layer TNL (Transport Network Layer) information corresponding to a Network element identifier according to an OMC configuration policy set by an OMC Network element.
Specifically, the OMC network element may be configured to store configuration data of a whole network under the 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.
The first configuration information is used to indicate a priority of each device, where each device includes an OMC network element and an MME (Mobility Management Entity) for providing TNL information. Such as: the priority of the OMC network element is higher than that of the MME.
The second configuration information is used to indicate an OMC query channel for TNL information. Such as: the OMC query channel may include an IP (Internet Protocol) address, a port, and a communication method; the TNL information may be service IP information of the target network element.
S103, if yes, the network element identification is sent to the OMC network element; and when TNL information corresponding to the network element identifier returned by the OMC network element is received, establishing a link with the target network element according to the TNL information corresponding to the network element identifier.
Specifically, the first LTE network element sends the network element identifier to the OMC network element, and the purpose of the first LTE network element is to obtain TNL information corresponding to the network element identifier, that is, TNL information of the target network element from the OMC network element.
When the first LTE network element establishes a link with the target network element, the method may include:
1.1, the first LTE network element uses a source IP as a service IP of the first LTE network element, uses a destination IP as an IP of a target network element, uses an EN-DC port number defined by 3GPP as 36412, and creates an EN-DC link SCTP (Stream Control Transmission Protocol) and an AP (Access Point).
1.2, the first LTE network element may send an SCTP INIT (initialization initiation) packet to the target network element, where an IP address parameter (address parameter) of the SCTP INIT packet 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, the source IP is used as the service IP of the target network element, the target IP is the IP of the first LTE network element, the port number is 36412 of EN-DC port number specified by 3GPP, and EN-DC SCTP and AP are created locally.
1.4, the first LTE network element and the target network element complete EN-DC self-establishment through four handshaking of SCTP.
In an exemplary scenario, as shown in fig. 2, eNodeB21 is the first LTE network element and eNodeB/gdnodeb 22 is the target network element. eNodeB21, in establishing a link between eNodeB21 and eNodeB/gdnodeb 22, may include:
2.1, eNodeB21 determines the network element identification of eNodeB/gNodeB 22;
2.2, the eNodeB21 determines whether to acquire TNL information of eNodeB/gNodeB22 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 that of the MME24, that is, the OMC network element 23 takes precedence, the TNL information of the eNodeB/gsdeb 22 may be acquired through the OMC network element 23 at this time; if the priority of the OMC network element 23 is lower than that of the MME24, that is, the MME24 takes precedence, the MME24 may obtain the TNL information of the eNodeB/gdnodeb 22.
2.3, if the eNodeB21 determines that the TNL information corresponding to the network element identifier is obtained through the OMC network element 23, sending the network element identifier to the OMC network element 23.
2.4, if receiving the TNL information corresponding to the network element identifier returned by the OMC network element 23, the eNodeB21 creates an EN-DC link SCTP and an AP according to the TNL information corresponding to the network element identifier, with the source IP being the service IP of the eNodeB21, the destination IP being the IP of the eNodeB/gsdeb 22, and the port number being the EN-DC port number 36412 specified by 3 GPP.
2.5, eNodeB21 may send SCTP INIT packet to eNodeB/gnnodeb 22, where the IP address parameter of the SCTP INIT packet carries the IP of eNodeB 21.
2.6, eNodeB/gNodeB22 extracts the IP of eNodeB21 from the SCTP INIT message, takes the source IP as the service IP of eNodeB/gNodeB22, takes the IP of eNodeB21 as the destination IP, takes the EN-DC port number specified by 3GPP as 36412, and creates EN-DC SCTP and AP locally.
2.7, eNodeB21 and eNodeB/gNodeB22 complete EN-DC self-establishment by four handgrips of SCTP.
As can be seen from the above embodiments, by determining a network element identifier of a target network element, where the target network element is used to represent a network element that needs to establish a link with a first LTE network element, according to an OMC configuration policy set by the OMC network element, it is determined whether to acquire, by the OMC network element, transport network layer TNL information corresponding to the network element identifier, and if so, the network element identifier is sent to the OMC network element, and when receiving TNL information corresponding to the network element identifier returned by the OMC network element, a link with the target network element is established according to TNL information corresponding to the network element identifier, so that the EN-DC self-establishment is completed by acquiring TNL information by the OMC network element, and the flexibility of link self-establishment is improved.
Further, based on the above method, in the above S101:

Further, based on the above method, the target network element is an NR network element; in performing S101, the method may include:
s1011, according to the ANR (Automatic Neighbor Relation), obtaining the NCGI (NR Cell Global Identifier) information of the NR network element.
Specifically, the first LTE network element may obtain NCGI information of the NR network element through an EN-DC ANR process.
Among them, the ANR function in the EN-DC ANR process is responsible for managing and maintaining a table called a concept neighbor relation table, i.e., nrt (conceptual neighbor relation). Also, in ANR, the neighbor detection function discovers and adds new neighbor cells to the NRT.
S1012, determining the network element identifier of the NR network element according to the NCGI information.
As can be seen from the foregoing embodiments, when the Network element identifier of the target Network element is determined, the determination may be performed according to ANR, so that linkage with the EN-DC ANR process is achieved, and SON (Self-Organizing Network) automation is completed.
Further, based on the above method, the OMC configuration policy includes: first configuration information and/or 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) which are used for providing TNL information; the second configuration information is used for indicating an OMC query channel of the TNL information; in performing S102, may include:
and 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 the OMC link state according to the second configuration information. The OMC link state may be a link state of the OMC network element 23 in fig. 2.
Specifically, if the first configuration information includes the OMC network element priority, it indicates that the priority of the OMC network element is greater than the priority of the MME; if the first configuration information comprises MME network element priority, the priority of the MME is larger than the priority of the OMC network element.
The OMC link state may specifically be: whether the OMC is online or not, whether a channel is available or not is inquired by the OMC, and the like.
S1022, if the OMC link state is in the available state, determining to acquire the TNL information through the OMC network element.
Specifically, the OMC link state is in an available state, which may indicate that the OMC is online and that the OMC query channel is 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, an MME link state is detected according to the second configuration information, and if the MME link state is in an available state, the TNL information is determined to be acquired through the MME. The MME link state may be the link state of MME24 in fig. 2.
Specifically, the MME link state may specifically be: whether the MME is online, whether a link between the MME and the first LTE network element is available, etc.
Further, based on the foregoing method, when the sending of the network element identifier to the OMC network element in S103 is executed, the method may include:
