step S202, detecting a release operation indicated by a connection release message sent by base station equipment;
step S204, in the case that the release operation is to switch the terminal equipment from being connected to the first communication node to being connected to the second communication node, responding to the connection release message, and detecting whether the first communication node deploys a target signaling interface or not to obtain a detection result;

Optionally, in this embodiment, the access method of the communication node provided by the present application has a wide application scenario, and may include, but is not limited to: LTE (Long Term Evolution ) network, 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) network, etc., the base station device, the communication node, and the target signaling interface of the communication node may be different devices for different network scenarios, such as: in an LTE network, an eNB (eNodeB, enhanced base station) is used as a base station device, a communication node is an MME (Mobility Management Entity ), and an S10 interface is used as a target signaling interface of the communication node; alternatively, in the 5G network, an NR (New Radio) base station is used as a base station device, a communication node is an AMF (Access and Mobility Management Function, access mobility management), and an N14 interface is used as a target signaling interface of the communication node. In the following embodiments, the above-mentioned access method of the communication node may be described by taking an LTE network scenario as an example, but the usage scenario is not further limited, that is, any procedure of switching a terminal device from being connected to a first communication node to being connected to a second communication node may use the access method of the communication node proposed by the present application.
In the solution provided in the step S202, the base station device may, but is not limited to, send a message to the terminal device and the communication node through a radio signal. The base station device that transmits the connection release message may be, but is not limited to, determined according to the network scenario, such as: in case the access method of the communication node is applied to a 5G network scenario, the base station device is an NR base station. Or, in case that the access method of the communication node is applied to the LTE scenario, the base station device is an eNB.
Alternatively, in this embodiment, the above connection release message may be, but not limited to, a message for instructing the terminal device to perform a release operation on a communication node currently in a connected state, or perform a connection operation on a communication node to be connected, where the connection release message may include, but is not limited to: RRC connection release message, etc.
Optionally, in this embodiment, the base station device may actively acquire a load balancing state of the communication node, and implement load balancing of the communication node by sending a connection release message to the terminal device, for example: the base station device actively acquires the load balance state of the communication node, sends a connection release message for indicating the release operation to the terminal device of the communication node with heavy load, thereby reducing the pressure of the communication node with heavy load, and sends the connection release message for indicating the connection operation to the terminal device by limiting access and transferring the terminal device to indicate the terminal device to access the communication node with light load, so as to realize the load balance of the communication node.
Alternatively, in this embodiment, the releasing operation that the terminal device can perform according to the connection release message may include, but is not limited to: location area update (Tracking Area Update, TAU) procedures, service request procedures, initial access procedures, etc.
Alternatively, in the present embodiment, the reason why the terminal device performs the release operation may be, but is not limited to, acquired through the connection release message, such as: the base station device sends a cause for instructing the terminal device to release the air interface with the first communication node as a connection release message to the base station device. Alternatively, the base station apparatus transmits a cause for instructing the terminal apparatus to release the air interface with the first communication node as one of the connection release messages to the base station apparatus.
In one exemplary embodiment, the release operation indicated by the connection release message sent by the base station device may be detected, but is not limited to, in the following manner: receiving the connection release message; extracting an air interface release reason from the connection release message, wherein the air interface release reason is used for indicating the reason for releasing the air interface of the first communication node; and determining the release operation according to the air interface release reason.
Alternatively, in this embodiment, the cause of the air interface release may include, but is not limited to, load balancing by the communication node or failure of the base station device.
Alternatively, in this embodiment, for the terminal device, extracting the air interface release reason from the connection release message may obtain a release operation corresponding to the air interface release reason, and the terminal device may be, but not limited to, configured to perform a release operation corresponding to the air interface release reason, for example: under the condition that the air interface release reason indicates the communication node to perform load balancing, the terminal equipment executes corresponding release operation (release connection with the communication node with heavy connection load) to relieve the pressure of the communication node with heavy load, and then executes access operation (access communication node with light connection load) to realize load balancing on the communication node through a location area updating flow. Or under the condition that the air interface release reason indicates that the base station equipment fails, the terminal equipment extracts the air interface release reason and executes the service request flow because the base station equipment automatically triggers the reset flow.
Alternatively, in the present embodiment, the communication node in the connected state with the terminal device may be determined as the first communication node, but is not limited to.
In one exemplary embodiment, the release operation may be determined according to the air interface release cause in one of, but not limited to, the following ways: determining that the release operation is to switch the terminal device from being connected to the first communication node to being connected to the second communication node in case the air interface release cause is for a first reason, wherein the first reason is caused by a load balancing initiation location area update; and under the condition that the air interface release reason is a second reason, determining that the release operation is to switch the terminal equipment from being connected to the first communication node to being connected to the second communication node, wherein the second reason is caused by the main-standby switching or the failure of the base station equipment.
Alternatively, in this embodiment, in the case where the communication node performs load balancing, the base station device may, but is not limited to, add a field "loadbalancegtauquired" to the connection release message to instruct the reason why the terminal device performs the release operation to perform load balancing. Or, in the case that the base station device has active/standby switching or failure, the base station device may, but is not limited to, add a field "eNBfailure" to the connection release message to indicate that the reason why the terminal device performs the release operation is that the base station device has active/standby switching or failure.
Optionally, in this embodiment, in a case where the terminal device identifies that the connection release message includes the first cause or the second cause, the terminal device is configured to determine, according to the first cause or the second cause, a release operation corresponding to the air interface release cause.
Alternatively, in this embodiment, the method may include, but is not limited to, indicating the cause of the air interface release using a field, and writing field values for indicating the first cause and the second cause into the connection release message, where the terminal device determines whether the cause of the air interface release in the connection release message is the first cause or the second cause by identifying the field values corresponding to the first cause and the second cause from the connection release message when the terminal device receives the connection release message, and obtains, as the release operation of the terminal device, the release operation corresponding to the first cause or the second cause when the cause of the air interface release is the first cause or the second cause.
In an alternative embodiment, an example of an air interface release cause is provided. Fig. 3 is a schematic diagram of a cause of air interface release according to an embodiment of the present application, and as shown in fig. 3, a terminal device (UE) receives a connection release message sent by a base station device, and the terminal device may determine a release operation from the connection release message by:
The terminal device (UE) receives a connection release message sent by the base station device, extracts a field (releaseause) for indicating a cause of air interface release from the connection release message, and obtains a field value in the field to obtain that the cause of air interface release is a first cause (loadbalancetaurerequired), so that the cause of air interface release is considered to be caused by the first cause, that is, a load balancing initiation location area update, and further, since the cause of air interface release is load balancing of a communication node, during load balancing of the communication node, the base station device obtains a load balancing state of the communication node, sends a connection release message for indicating a release operation to the terminal device of the communication node with a heavier load, so that the release operation corresponding to the first cause can be to release the connection with the first communication node, thereby alleviating the pressure of the communication node with a heavier load, and sends the connection release message for indicating the connection operation to the terminal device to access the communication node with a lighter load to the terminal device by limiting access, so that the first corresponding release operation can also be to establish a connection with the second communication node to realize load balancing of the communication node.
Similarly, in the case where the release operation is caused by the base station device performing active-standby switching or failure, the base station device may, but is not limited to, write the second cause (eNBfailure) as a field value of the air interface release cause field into the connection release message, and further, taking the air interface release cause as an example, the base station device configures a plurality of S1 interfaces (interfaces for radio resource control and user data transmission) because the base station device fails, in the case where the S1 interface currently used by the base station device fails, the base station device releases the terminal device to Access other standby S1 interfaces, and since the base station device actively triggers a RESET procedure, the base station device notifies the terminal device and the communication node of releasing the context information of the terminal device, and therefore, the release operation corresponding to the second cause may be to release the connection with the first communication node, but since the base station device does not have a NAS (Non-Access Stratum) layer function between the communication node and the terminal device, only can release the air interface connection of the terminal device, and cannot release all resources of the terminal device, and the terminal device may initiate a release of all resources, and the terminal device may immediately initiate a release of the service request for the second cause to correspond to the second communication node.
As can be seen from the above, in the case where the air-interface release cause is the first cause or the second cause, the release operation corresponding to the air-interface release cause may include, but is not limited to: the connection with the first communication node is released and the connection with the second communication node is established.
In the technical solution provided in step S204, the deployment situation of the first communication node on the target signaling interface may be obtained, but is not limited to, when the first communication node performs initial attachment, for example: since the first communication node is a communication node in a connection state with the terminal device, when the terminal device performs an initial attachment procedure with the first communication node, an information item for indicating whether the first communication node supports the target signaling interface is added to an initial context establishment request message sent by the first communication node to the base station device.
Optionally, in this embodiment, the target signaling interface is an interface on a communication node, and the target signaling interface is an interface disposed on the communication node in the LTE network, which is described as an example: in the case of a terminal equipment (UE) performing a movement across communication nodes (MME), a connection of an S10 interface (target signaling interface) may be, but is not limited to, established between communication nodes, including necessary tunnel establishment, signaling transfer, and MME POOL (mobility management entity POOL) formation, so as to perform data transfer of a control plane, but not every communication node may provide target signaling interface support due to constraints of service requirements, environmental restrictions, etc.
Optionally, in this embodiment, the target signaling interface may be, but is not limited to be, used for data transmission between the first communication node and the second communication node, and the target signaling interface may include, but is not limited to, the following: an S10 interface of MME in LTE network, an N14 interface of AMF in 5G network, etc.
In an exemplary embodiment, the first communication node may detect whether the target signaling interface is deployed by, but not limited to, the following manner, to obtain a detection result: extracting node information of the first communication node from a storage space of the terminal equipment, wherein the node information is stored into the storage space when the terminal equipment establishes connection with the first communication node; under the condition that the node information comprises the first communication node with the corresponding relation and a first field value, determining that the detection result is that the target signaling interface is deployed on the first communication node, wherein the first field value is used for indicating that the target signaling interface is deployed; and under the condition that the node information comprises the first communication node and a second field value with a corresponding relation, determining that the detection result is that the target signaling interface is deployed on the first communication node, wherein the second field value is used for indicating that the target signaling interface is not deployed.
Optionally, in this embodiment, the storage space of the terminal device is used to store a plurality of items of data related to the terminal device, and the node information of the first communication node may include, but is not limited to: an interface that the first communication node has deployed, an interface that the first communication node can deploy, a use case of the interface that the first communication node deploys, and the like.
Optionally, in this embodiment, the first communication node is a communication node in a connection state with a terminal device, and the method for establishing connection between the terminal device and the first communication node may include, but is not limited to, the following steps: location area update (Tracking Area Update, TAU) procedures, service request procedures, initial access procedures, etc.
Optionally, in this embodiment, the first communication node sends the node information of the first communication node to the base station device, and the terminal device may, but is not limited to, obtain the node information of the first communication node and store the node information in a storage space during interaction with the base station device, for example: the first communication node sends an initial context establishment request message carrying node information of the first communication node to the base station equipment, and the terminal equipment acquires the node information of the first communication node from the base station equipment in the process of initial attachment of the terminal equipment to the base station equipment.
In an exemplary embodiment, before the extracting the node information of the first communication node from the storage space of the terminal device, the node information may be, but is not limited to, extracted in the following manner: receiving a target configuration message sent by the first communication node in the process of establishing connection between the terminal equipment and the first communication node, wherein the target configuration message is used for reconfiguration with the first communication node; extracting a field value of a target field from a target message segment carried by the target configuration message, wherein the target field is used for indicating whether the first communication node deploys a target signaling interface, and the field value comprises the first field value or the second field value; and storing the first communication node and the field value which have the corresponding relation as the node information into the storage space.
