Background

With the continuous development of network technology, edge computational power networks have become the current research focus. Wherein, the edge computational force network may include: a plurality of edge devices, one or more multi-access edge computing (MEC) devices, and a computational network platform. One MEC device may control and manage the computing resources of multiple edge devices; the computing network platform can control and manage a plurality of MEC equipment; the edge force calculation network realizes the superposition and integration of force calculation through the cooperative work of the edge equipment, the MEC equipment and the force calculation network platform.

When an MEC device controls and manages the computing resources of a plurality of edge devices, it is first necessary to establish a session connection with an edge device, i.e., only the computing resources of the edge device in the session connection state are available to the MEC device. In an edge computing network, each edge device needs to periodically send control signaling to the MEC device to keep the respective session in a connected state.

When the number of edge devices managed by the MEC device is very large, the MEC device needs to process a large number of control signaling messages. In this case, there may be a case that all control signaling cannot be processed in time, so that part of the session oscillates, the use of the computing resources of part of the edge devices is affected, and the stability of the computing resources is reduced.

Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance. The technical features described in the first and second descriptions have no sequence or magnitude order.

In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present relevant concepts in a concrete fashion for ease of understanding.

In the description of the present application, a "/" indicates a relationship in which the objects associated before and after are an "or", for example, a/B may indicate a or B; in the present application, "and/or" is only an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. Also, in the description of the present application, "a plurality" means two or more than two unless otherwise specified. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

In the embodiments of the present application, at least one may also be described as one or more, and a plurality may be two, three, four or more, which is not limited in the present application.

For the sake of understanding, the technical terms related to the present application are explained first.

A session may refer to a process in which an edge device communicates with an MEC device. Wherein, one MEC device may include a plurality of sessions, each session uniquely corresponding to one edge device. The state of the session may include: connected state, disconnected state.

The lifetime of the session may refer to the longest time for maintaining the session in the connection state without updating the session state after the session is established.

The service packet may refer to a data packet sent between devices. The messages sent between the devices may include service messages and non-service messages (control signaling messages).

The edge device may refer to a terminal device with computing capability connected to the MEC device, for example, the edge device may be a mobile phone, a computer, or the like.

For ease of understanding, the session establishment procedure will be briefly described.

The following takes the process of the MEC device establishing the session 1 with the edge device 1 as an example, and the session establishment process is briefly described.

The method comprises the steps that the edge device 1 sends a signaling message for requesting to establish a session to the MEC device, the MEC device receives a request instruction, obtains a (media access control, MAC) address of the edge device 1 in the request instruction, and establishes the session 1 with the edge device 1; then set the lifetime of session 1 and monitor the duration of the hold of session 1. The MEC equipment sends a response of successful session establishment to the edge equipment 1; the edge device 1 receives the response of successful session establishment sent by the MEC device.

For example, the duration of the session may be monitored by setting the duration of the session's lifetime by a timer.

It is to be understood that, referring to the process of establishing session 1, the MEC device may establish multiple sessions with multiple edge devices, which is not described herein again.

After the session is successfully established, the state of the session needs to be continuously updated to ensure that the computing resources of the edge device are available.

Taking the update session 1 as an example, the scheme for updating the session state at present is as follows: after receiving a response that the session 1 is successfully established, the edge device 1 periodically sends a signaling message for maintaining the session 1 connection to the MEC device; the MEC equipment receives the signaling message for maintaining the session connection, updates the state of the session 1 into connection, resets the survival time of the session 1 and monitors the maintaining time of the session 1. The MEC device sends a response to the edge device 1 that session 1 remains successful.

Wherein, the period duration for maintaining the session connection should be less than the lifetime duration of the session.

It should be noted that the signaling for establishing the session and the signaling for maintaining the session may be the same instruction or different instructions; the response that the session establishment is successful and the response that the session is maintained to be successful may be the same instruction or different instructions.

It can be understood that, for the edge device whose session is in a connected state, data interaction can be performed with the MEC device, so that the computation force superposition and integration can be realized.

When the number of edge devices managed by the MEC device is very large, the number of corresponding sessions is very large, and the MEC device needs to process a large number of control signaling messages in order to maintain the connection of the sessions; in this case, it may be that all control signaling cannot be processed in time, so that part of the session oscillates, the use of the computing resources of part of the edge devices is affected, and the stability of the computing resources is reduced.

Based on this, the application provides a session processing method, which can update the session corresponding to the identifier to a connection state through the identifier of the edge device in the received data message, thereby avoiding the interruption of the session caused by too much control signaling which cannot be processed in time; the number of control signaling is reduced, and the stability of conversation and the stability of computing resources are improved.

In order to facilitate understanding of the implementation process of the scheme in the embodiment of the present application, a network architecture in the embodiment of the present application is first described. The session processing method in the embodiment of the present application may be applied to the following network architecture.

The following describes the components of the MEC apparatus 20 in detail with reference to fig. 2:

For example, the processor 21 is a Central Processing Unit (CPU), and may be an Application Specific Integrated Circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application, such as: one or more microprocessors (digital signal processors, DSPs), or one or more Field Programmable Gate Arrays (FPGAs).

In particular implementations, processor 21 may include one or more CPUs such as CPU0 and CPU1 shown in fig. 2 as one example.

In particular implementations, the MEC apparatus 20 may include a plurality of processors, such as the processor 21 and the processor 25 shown in fig. 2, as an example. Each of these processors may be a single-Core Processor (CPU) or a multi-Core Processor (CPU).

The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of illustration, only one thick line is shown in FIG. 2, but it is not intended that there be only one bus or one type of bus.

It is noted that the components shown in fig. 2 do not constitute a limitation of the MEC apparatus, and that the MEC apparatus may comprise more or less components than shown, or some components in combination, or a different arrangement of components than those shown in fig. 2.

Specifically, the processor 21 executes the following functions by running or executing software programs and/or modules stored in the memory 22 and calling data stored in the memory 22:

receiving N service messages sent by edge equipment; n is greater than or equal to 1; acquiring identifiers of M edge devices from N service messages; m is less than or equal to N; and updating the state of the session corresponding to the identifications of the M edge devices to be a connection state.

On the other hand, the embodiment of the present application provides a session processing method, which may be applied to the MEC device 20 shown in fig. 2. For updating the state of the session comprised by the MEC device. The process of updating the state of the session included in each MEC device is similar, and a single MEC device is taken as an example and is described.

The session processing method provided by the embodiment of the application is used for updating the state of a session after the MEC equipment establishes a session connection. Specifically, the session processing method provided by the embodiment of the present application can be independently used for updating the state of the session; or, the session processing method provided by the embodiment of the present application may be used for supplementing the existing state of updating the session through signaling.

When the session processing method provided by the embodiment of the application is used for supplementing the state of the existing session updated through signaling, the MEC equipment receives the control signaling; or when the update condition in the embodiment of the present application is satisfied, the corresponding session state is updated.

Specifically, fig. 3 is a flowchart of a session processing method provided in the embodiment of the present application, and as shown in fig. 3, the method may include:

s301, the MEC equipment receives N service messages sent by the edge equipment.

Wherein N is greater than or equal to 1.

Specifically, S301 may be implemented as: the MEC equipment continuously receives N service messages sent by the edge equipment through a communication interface of the MEC equipment. In other words, the MEC device continuously receives N service packets sent by the edge device through its data unit.

In a possible implementation manner, the N service packets sent by the MEC device and received by the edge device may be a service packet sent by one edge device.

In another possible implementation manner, the N service packets sent by the MEC device and received by the edge device may be service packets sent by multiple edge devices.

It should be noted that the time for the MEC device to execute S301 once is the interval between two session state updates.

S302, the MEC equipment acquires the identifiers of the M edge devices from the N service messages.

Wherein M is less than or equal to N.

The specific content of the identifier of the edge device may be configured according to actual requirements, which is not specifically limited in the embodiment of the present application.

Illustratively, the identification of the edge device may include, but is not limited to, any of: MAC address of edge device, IP address of edge device.

In one possible implementation manner, S302 may be implemented as: the MEC equipment can analyze the identifier of the edge equipment which sends a service message from the message header of the service message every time the MEC equipment receives the service message; the MEC equipment continuously receives and analyzes; thereby obtaining the identifiers of M edge devices in the received N service messages.

In another possible implementation manner, S302 may be implemented as: after the MEC equipment can receive a plurality of service messages, the mark of the edge equipment sending the message is analyzed from the message header of each service message, and the MEC equipment continuously receives and analyzes the message; thereby obtaining the identifiers of M edge devices in the received N service messages.

In yet another possible implementation manner, S302 may be implemented as: after the MEC device can receive the N service messages, the identifier of the edge device that sends the message is respectively analyzed from the message header of each service message, so as to obtain the identifiers of M edge devices in the received N service messages.

And S303, the MEC equipment updates the state of the session corresponding to the identifications of the M edge equipment into a connection state.

The execution timing of S303 may be configured according to actual requirements, which is not limited in this embodiment of the present application.

In one possible implementation, S303 may be directly executed after S302 is executed.

In another possible implementation, S303 may be performed periodically.

In this possible implementation, the duration of the execution period may be configured according to actual requirements.

Specifically, when the duration of the execution cycle is a preset duration, the MEC device determines that a timing duration counted from the last time of updating the state of the session between the MEC device and the first edge device reaches the preset duration; s303 is performed.

Wherein the preset duration is less than the lifetime of each session.

Specifically, the implementation of S303 may include, but is not limited to, methods 1 to 3 described below.

In the method 1, each time the MEC device acquires the identifier of the edge device in one message, the state of the session corresponding to the identifier of the edge device in the message is updated to a connection state.

Where M equals 1 and N equals 1.

Exemplarily, each time the MEC device acquires the identifier of the edge device in one message, the MEC device updates the state of the session corresponding to the identifier of the edge device in the message to a connection state; and setting the survival time of the conversation and monitoring the holding time of the conversation.

Method 2, when the MEC device obtains the identifier of an edge device in N messages, the state of the session corresponding to the identifier of the edge device is updated to a connection state.

Wherein M is equal to 1 and N is greater than 1.

Illustratively, each time the MEC device acquires the identifier of an edge device in N messages, the state of the session corresponding to the identifier of the edge device is updated to a connection state; and setting the survival time of the conversation and monitoring the holding time of the conversation.

And 3, the MEC equipment acquires the identifiers of the M edge devices in the N messages, and updates the states of the sessions corresponding to the identifiers of the M edge devices into a connection state.

Wherein M is greater than 1 and N is greater than 1.

Exemplarily, the MEC updates the state of the session corresponding to the identifiers of the M edge devices to the connection state if the identifiers of the M edge devices in the N messages are present; and setting the time-to-live of the M conversations and monitoring the time-to-hold of the M conversations.

It will be appreciated that for a session whose session state has not been re-updated to a connected state for the lifetime, the MEC device will automatically update the state of the session to disconnected. That is, the MEC device automatically disconnects the session when the holding time period of the session reaches the lifetime.

Further, before executing the session processing provided in the embodiment of the present application, it may also be determined whether the number of sessions established with the MEC device is large, and when the number is large, the session processing method provided in the embodiment of the present application is executed.

Specifically, as shown in fig. 4, the method may further include the following S304.

S304, the MEC device determines that the number of sessions established with the MEC device is greater than or equal to a first threshold.

Wherein the first threshold is greater than 1.

The size of the first threshold may be configured according to actual requirements, which is not specifically limited in the embodiment of the present application.

Illustratively, the first threshold may be determined in accordance with the capability of the MEC device to process signaling.

The following briefly describes the session processing method provided by the present application with a specific embodiment.

Fig. 5 illustrates a session processing scenario, which includes one MEC device and 3 edge devices (edge device a, edge device B, and edge device C).

The method comprises the steps that a session A is established between edge equipment A and MEC equipment, a session B is established between the edge equipment B and the MEC equipment, and a session C is established between the edge equipment C and the MEC equipment; respectively setting and starting a timer of each session; the MEC device then interacts data with edge device a, edge device B, and edge device C via session a, session B, and session C, respectively. It is assumed that each time an MEC device receives a packet, it needs to update its corresponding session state.

At the first moment, the MEC equipment receives the message A, and the MEC equipment analyzes that the identifier of the edge equipment in the message A is 192.112.0.1; and according to the identification, the session to be updated is obtained as session A, then the state of the session A is updated again to be a connection state, and the timer of the session A is reset.

At the second moment, the MEC equipment receives the message B, and the MEC equipment analyzes that the identifier of the edge equipment in the message B is 192.112.8.11; and according to the identification, the session to be updated is obtained as the session B, then the state of the session B is updated again to be the connection state, and the timer of the session B is reset.

At the third moment, the MEC device receives the message C, and the MEC device analyzes that the identifier of the edge device in the message C is 192.112.7.21; and according to the identification, obtaining that the session to be updated is the session C, then updating the state of the session C to be the connection state again, and resetting the timer of the session C.
