Description

Control method and edge arithmetic device for network communication system

Technical Field

The present invention relates to a method for controlling a network communication system and an edge computing device, and more particularly, to a method for controlling a network communication system and an edge computing device, which perform control processing according to the adjacency relationship between the edge computing devices.

Background

With the popularization of mobile devices and the growth of network services such as communication software and streaming video, more and more enterprises are gradually expanding many business services to intelligent devices to increase the convenience of users, and the traffic of mobile networks is continuously increasing. Under this trend, the load traffic of the normal backhaul (backhaul) network is gradually insufficient. In addition, the remote cloud computing center also needs to be able to bear the increasing amount of computation. In other words, past network architectures have presented considerable challenges as communication technology has advanced.

In such a case, a Mobile Edge Computing (MEC) architecture is proposed in order to solve the problem of increasing traffic. Mobile edge computing is a concept of a new network architecture, such as literal meaning, and is an environment that provides cloud computing capability and Information Technology (IT) services at the edge of a mobile network. This concept was developed by the European Telecommunications Standards Institute (ETSI), and the main idea was to reduce the increasing operating pressure of core network devices and to allow mobile operators to create unique mobile experiences for customers.

However, currently, the moving edge calculation still faces many problems, so when the moving edge calculation is used to deal with the related problems, such as data cache (content cache), smart migration (smart relocation) and hand over (hand over), the performance of the moving edge calculation obviously still has room to be improved.

Disclosure of Invention

The present invention is directed to a method for controlling a network communication system and an edge computing device, so as to overcome the problem of gradual increase of network traffic and cloud computation and improve the performance of mobile edge computation.

The invention provides a control method of a network communication system, which is suitable for the network communication system. The base station network management server is in communication connection with the first edge operation platform and the first base station. In a method for controlling a network communication system, a first base station first obtains neighboring base station identification information of a neighboring base station. The first communication range of the first base station overlaps with a portion of the second communication range of the neighboring base station. And the first base station provides the first base station neighboring information to the base station network management server. Wherein the first base station neighbor information includes neighbor base station identification information. And the first edge computing platform obtains the first base station adjacent information from the base station network management server. In addition, the first edge computing platform generates first platform neighbor information. The first platform neighbor information includes first platform identification information and neighbor base station identification information of the first edge computing platform. And when the solicited signal is received from the second edge operation platform, judging whether the solicited signal is matched with the adjacent information of the first platform. And when the request signal is judged to be matched with the adjacent information of the first platform, providing the identification information of the first platform to the second edge operation platform.

In some embodiments of the present invention, the network communication system further has a central control server. The first edge operation platform is in communication connection with the central control server. In the control method of the network communication system, the first edge operation platform provides the first platform adjacent information to the central control server. When the central control server receives the request signal from the second edge operation platform, the central control server judges whether the request signal is matched with the identification information of the adjacent base station. When the central control server judges that the solicited signal is matched with the adjacent information of the first platform, the central control server provides the identification information of the first platform to the second edge operation platform.

In some embodiments of the present invention, when the first edge computing platform receives the request signal broadcast by the second edge computing platform, the first edge computing platform determines whether the request signal matches the first platform neighbor information. And when the first edge operation platform judges that the solicited signal is matched with the adjacent information of the first platform, the first edge operation platform provides the first platform identification information for the second edge operation platform.

The invention also provides an edge arithmetic device which is used for connecting the base station network management server and the first base station in a communication way. The edge computing device has a processor and a memory. The processor is electrically connected with the memory. The memory stores a plurality of instructions. When the processor executes the instruction, the edge computing device runs an edge computing platform, and the edge computing platform is used for executing the following steps: obtaining base station identification information of a second base station from a base station network management server; the second communication range of the second base station overlaps with the first communication range of the portion of the first base station; generating platform adjacent information, wherein the platform adjacent information comprises platform identification information of the edge operation platform and base station identification information of a second base station; and providing platform adjacent information to the central control server so as to provide the platform adjacent information to the other edge operation platform which is in communication connection with the central control server through the central control server, wherein the platform adjacent information comprises base station identification information of the second base station.

The invention also provides another edge arithmetic device which is used for connecting the base station network management server and the first base station in a communication way. The other edge computing device has a processor and a memory. The processor is electrically connected with the memory. The memory stores a plurality of instructions. When the processor executes the instruction, another edge computing device runs an edge computing platform, and the edge computing platform is used for executing the following steps: when the edge operation platform receives a request signal broadcast by another edge operation platform, the other edge operation platform judges whether the request signal is matched with platform adjacent information; when the other edge computing platform judges that the request signal is matched with the platform adjacent information, the other edge computing platform provides platform identification information for the other edge computing platform.

In summary, the present invention provides a control method and an edge computing device for a network communication system. In the control method and the edge operation device of the network communication system, an edge operation platform is executed, an adjacent relation can be established with the adjacent edge operation platform, and the related information of the adjacent edge operation platform is obtained. Therefore, when processing operation, the edge computing platform can refer to the information of another edge computing platform in addition to the information of the edge computing platform and the information of the base station. Since the mobile device may switch to different base stations, the information requirement or the computation requirement of the mobile device may be burdened by different edge computing devices. Thus, the edge computing platform is able to make a more macroscopic determination, taking into account the information of adjacent edge computing platforms.

Detailed Description

In order that the objects, technical solutions and advantages of the present invention will become more apparent, the present invention will be further described in detail with reference to the accompanying drawings in conjunction with the following specific embodiments.

Fig. 1 is a functional framework diagram of a network communication system according to a first embodiment of the present invention, and fig. 2 is a method flowchart of a method for controlling a network communication system according to an embodiment of the present invention. The control method of the network communication system shown in fig. 2 is applied to the network communication system 1a shown in fig. 1. The network communication system 1a includes a first edge computing platform 12a, a first base station 14a (base station), and a base station network management server 16 a. The base station network management server 16a is communicatively connected to the first edge computing platform 12a and the first base station 14 a. The first edge computing platform 12a is communicatively coupled to a first base station 14 a. Although the first edge computing platform 12a is illustrated as being communicatively coupled to one base station, in practice, the first edge computing platform 12a may be communicatively coupled to a plurality of base stations, and the number is not limited to the illustrated number. The communication connection refers to the wired communication or wireless communication between the devices, but does not limit whether the communication connection between the devices must be permanently established. The first base station 14a can support 4G (4th generation) communication protocol and signal transmission. The bs management server 16a is, for example, a Network Management System (NMS) or an Element Management System (EMS). The above description is exemplary only, and not intended to be limiting.

The first edge computing platform 12a refers to a physical server with computing capability, for example, or the first edge computing platform 12a may also be an application program of one of virtual machines (virtual machines) running in the server. Architecturally, the first edge computing platform 12a is also located at the edge of the network and thus relatively close to the user terminal. More specifically, the network architecture uses, for example, a cloud server (cloud server) or the internet (internet) as a network core, and the user terminal is located at the opposite periphery of the network architecture and connected to the cloud or the internet through the network. The Network edge refers to, for example, a boundary between a Local Area Network (LAN) close to a user end and the internet, but is not limited thereto. The user terminal is a mobile electronic device such as a smart phone, a tablet or a notebook, and is illustrated as a terminal device 30 in fig. 1. The terminal device 30 connects to the internet or communicates with another terminal device at a remote location via the first base station 14 a.

The first edge computing platform 12a is used to provide services to the terminal device 30. Therefore, a relatively complicated operation can be performed by the first edge operation platform 12a, and the load on the terminal device 30 can be reduced. Alternatively, the first edge computing platform 12a is used to store or process relevant information that the terminal device 30 may access. The above is merely exemplary, and the services provided by the first edge computing platform 12a are not limited thereto.

Referring to fig. 1 and fig. 2, in step S201 of the method for controlling a network communication system, first, the first base station 14a obtains neighboring base station identification information of a neighboring base station. The first communication range of the first base station 14a overlaps with a portion of the second communication range of the neighboring base station. In fig. 1, the neighboring base station is, for example, the second base station 24. The meaning of overlapping communication ranges means: when the terminal device 30 is located at the intersection (or what can be understood as an overlap) of the first communication range and the second communication range, both the first base station 14a and the second base station 24 have the capability to communicate with the terminal device 30. In practice, the first base station 14a obtains the neighbor base station identification information of the neighbor base station through Automatic Neighbor Relation (ANR), for example. The automatic Neighbor Relation is, for example, an automatic management Neighbor Relation Table (NRT). The Identification information of the neighboring base station is, for example, an Identifier (ID) or an internet protocol address (IP address) of the neighboring base station (in this case, the second base station 24).

The neighboring base station is associated with another edge computing platform, for example. In this embodiment, the second base station 24 and the second edge computing platform 22 are taken as an example for illustration. The base station network management server 26 is communicatively connected to the second edge computing platform 22 and the second base station 24, and the second edge computing platform 22 is communicatively connected to the second base station 24. The details of the second edge computing platform 22, the second base station 24 and the base station network management server 26 are similar to those of the first edge computing platform 12a, the first base station 14a and the base station network management server 16a, and are not repeated herein.

In step S203, the first base station 14a provides the first base station neighbor information to the base station network management server 16 a. Wherein the first base station neighbor information includes neighbor base station identification information. In other words, the first base station neighbor information is used to indicate, for example, the base station neighboring the first base station 14a, which is the second base station 24 in this embodiment. In step S205, the first edge computing platform 12a obtains the first bs neighbor information from the bs network management server 16 a. In step S207, first platform neighboring information is generated by the first edge computing platform 12 a. The first platform neighbor information includes first platform identification information of the first edge computing platform 12a and neighbor base station identification information of the first edge computing platform 12 a. In this embodiment, the first platform identification information is, for example, an identifier or an internet protocol address of the first edge computing platform 12 a.

In step S209, when the solicitation signal is received from the second edge computing platform 22, it is determined whether the solicitation signal matches the first platform neighbor information. In step S111, when the solicitation signal is determined to match the first platform neighboring information, the first platform identification information is provided to the second edge computing platform 22. In practice, the present invention provides several different operation modes in step S209 and step S211, which are illustrated separately below.

Referring to fig. 3 for explaining an operation manner thereof, fig. 3 is a method flowchart of a part of steps of a control method of a network communication system according to a second embodiment of the present invention. As shown in fig. 3, in step S301, when the first edge computing platform 12a receives the solicited signal broadcast by the second edge computing platform 22, the first edge computing platform 12a determines whether the solicited signal matches the first platform neighboring information. More specifically, the first edge computing platform 12a is used for determining whether the request signal has the relevant content of the first platform neighboring information recorded therein, for example, to determine whether the request signal matches the first platform neighboring information. Ideally, the solicitation signal includes the neighboring base station identification information of the neighboring base station of the first base station 14a, i.e., the base station identification information of the second base station 24. In this embodiment, when the solicitation signal includes neighboring base station identification information of a neighboring base station of the first base station 14a, the first edge computing platform 12a determines that the solicitation signal matches the first platform neighboring information. Conversely, the first edge computing platform 12a may also receive the solicited signal broadcast by the other edge computing platforms, but the communication range of the base station corresponding to the other edge computing platforms does not overlap with the first communication range of the first base station 14a, so the solicited signal provided by the other edge computing platforms does not have the identification information of the neighboring base station of the first base station 14a, and the first edge computing platform 12a thus determines that the solicited signal provided by the other edge computing platforms does not match with the neighboring information of the first platform.

In step S303, when the first edge computing platform 12a determines that the solicitation signal matches the first platform neighboring information, the first edge computing platform 12a provides the first platform identification information to the second edge computing platform 22. When the second edge computing platform 22 obtains the first platform identification information, the second edge computing platform 22 can establish an adjacent relationship with the first edge computing platform 12a according to the first platform identification information, and communicate with the first edge computing platform 12a to exchange information. Conversely, when the first edge computing platform 12a determines that the requested signal does not match the first platform neighbor information, the first edge computing platform 12a does not provide the first platform identification information to the source of the requested signal. In practice, the first edge computing platform 12a and the second edge computing platform 22 may define each other as an adjacent edge computing platform in the corresponding information field by recording the platform identification information of each other. In one embodiment, when the second edge computing platform 22 receives the first platform identification information provided by the first edge computing platform 12a, the second edge computing platform 22 also provides its own platform identification information to the first edge computing platform 12 a. When the first edge computing platform 12a receives the platform identification information provided by the second edge computing platform 22, the first edge computing platform 12a establishes an adjacent relationship with the second edge computing platform 22. The way to establish the adjacent relationship is freely designed by those skilled in the art after referring to the present specification, but all methods that enable one edge computing platform to know that another edge computing platform is an adjacent edge computing platform belong to the protection scope of the present invention.

In terms of structure, since the first communication range of the first base station 14a at least partially overlaps the second communication range of the second base station 24, the terminal device 30 is likely to move to the second communication range of the second base station 24. In other words, both the first edge computing platform 12a and the second edge computing platform 22 may provide services to the terminal device 30. Therefore, under the control method of the network communication system provided by the present invention, the first edge computing platform 12a and the second edge computing platform 22 can establish the neighboring relationship sharing information by the aforementioned method, so as to perform more efficient determination and provide better service to the terminal device 30.

Referring to fig. 4 and fig. 5 to illustrate another operation manner, fig. 4 is a functional framework diagram of a network communication system according to a third embodiment of the present invention, and fig. 5 is a method flowchart of a part of steps of a control method of the network communication system according to the third embodiment of the present invention. In the third embodiment, the network communication system 1b also has a central control server 18 b. The central control server 18b is communicatively connected to the first edge computing platform 12 b. As shown in fig. 5, in step S501, the first edge computing platform 12b provides the first platform neighboring information to the central control server 18 b. In step S503, when the central control server 18b receives the request signal from the second edge computing platform 22, the central control server 18b determines whether the request signal matches the identification information of the neighboring base station. As described above, the first platform neighbor information includes the first platform identification information of the first edge computing platform 12b and the neighbor base station identification information of the first edge computing platform 12 b. In step S505, when the central control server 18b determines that the solicitation signal matches the first platform neighboring information, the central control server 18b provides the first platform identification information to the second edge computing platform 22.

Therefore, the central control server 18b can play a matching role, and the second edge computing platform 22 can establish a clear communication connection with the central control server 18b and fixedly provide the request signal to the central control server 18b, thereby avoiding the problem that whether the request signal is received or not cannot be determined and the problem of safety when the request signal is broadcast. On the other hand, in this embodiment, only the first edge computing platform 12b is taken as an example to provide the first platform neighboring information to the central control server 18b, but actually, the second edge computing platform 22 may also provide the corresponding platform neighboring information to the central control server 18b for the first edge computing platform 12b to query. In other words, the first edge computing platform 12b can also query the central control server 18b for neighboring edge computing platforms and establish a neighboring relationship therewith. In addition, the central server 18b can also obtain platform neighboring information from other edge computing platforms, not limited to the first edge computing platform 12b and the second edge computing platform 22. Through the above embodiment, the adjacent relationship between adjacent edge computing platforms can be established, and the embodiment shown in fig. 4 and fig. 5 is used to continue to describe the related application for establishing the adjacent relationship.

As described above, the first edge computing platform 12b is used to provide services to the terminal device 30. In one embodiment, the first edge computing platform 12b stores a plurality of first data for the terminal device 30 to access through the first storage space. The content and form of the first data are not limited herein. In practice, the first storage space has a limited size, so when the first storage space is not enough, the first edge computing platform 12b needs to sort the first storage space, for example, delete some first data or replace some first data, so as to avoid that data that would be needed by the user can not be stored any more.

In one embodiment, the first edge computing platform 12b stores a plurality of first data in a first storage module. Each first data corresponds to a first access record. The second edge computing platform 22 stores a plurality of second data in a second storage module. Each second data corresponds to a second access record. The first edge computing platform 12b can also optimize the content stored in the first storage module according to the related information of the second edge computing platform 22. Referring to fig. 6, the data access is described, and fig. 6 is a flowchart illustrating a part of steps of a control method of a network communication system according to a fourth embodiment of the present invention. In step S601, when the remaining storage space of the first edge computing platform 12b is smaller than or equal to the predetermined size, the first edge computing platform 12b communicates with the second edge computing platform 22 to determine whether each of the first data is the same as one of the second data. In step S603, when determining that one of the first data is the same as one of the second data, the first edge computing platform 12b selectively deletes a portion of the first data according to the first access record and the second access record. The present invention further provides various embodiments of step S603, which are illustrated below.

Referring to fig. 7, fig. 7 is a flowchart illustrating a portion of steps of a control method of a network communication system according to a fifth embodiment of the present invention. In this embodiment, the first access record records a first access time of each first data in the default time interval, and the second access record records a second access time of each second data in the default time interval. In the step of selectively deleting a portion of the first data according to the first access records and the second access records, the method further comprises the following steps: step S701, determining whether there is duplicate data in the first data and the second data by using a first edge computing platform; step S703, when the first edge computing platform determines that a first repeating data in the first data is the same as a second repeating data in the second data, the first edge computing platform sums a first access frequency of the first repeating data and a second access frequency of the second repeating data, and the first edge computing platform replaces the first access frequency of the first repeating data according to the summed result to update the first access frequency of the first repeating data; in step S705, the first edge computing platform deletes the data with the smallest first access frequency from the first data. The first edge computing platform is not limited to the first edge computing platform in the foregoing embodiments. This is described later with reference to the first edge computing platform 12 b.

Please refer to table 1 and table 2 to illustrate this example. Table 1 shows a plurality of first data and corresponding first access times stored in the first edge computing platform 12b, and table 2 shows a plurality of second data and corresponding second access times stored in the second edge computing platform 22. More specifically, the first edge stage 12b stores data #1, data #16 and data #20, and the second edge stage 22 stores data #1, data #4 and data # 20. The first edge computing platform 12b and the second edge computing platform 22 both store data #1 and data #20, and the data #1 and the data #20 are, for example, the aforementioned first repeating data (relative to the first edge computing platform 12 b) or the second repeating data (relative to the second edge computing platform 22). As mentioned above, the first access times and the second access times are, for example, the access times of each corresponding data in a default time. The preset time is, for example, an hour, a time set by a user, or a time range of the push-back at the current time point.

TABLE 1

TABLE 2

In the case of the first edge computing platform 12b, in a conventional approach, the first edge computing platform 12b only considers the first access times of the first data. Therefore, when the storage space of the first storage module of the first edge computing platform 12b is not enough, the first edge computing platform 12b may delete the first data with the least first access frequency. With respect to the information in the above table, the first edge computing platform 12b has deleted data #1 or replaced data #1 with new data. However, as shown in table 2, the second access count corresponding to the data #1 is not the smallest among the second data, and is even higher than the first access count of a part of the first data.

As described above, since the first communication range of the first base station 14b overlaps at least a part of the second communication range of the second base station 24, other terminal apparatuses originally communicatively connected to the second base station 24 are likely to move and be switched to the first base station 14 b. These end devices are originally served by the second edge computing platform 22. After being handed off to the first base station 14b, the terminal devices are served by the first edge computing platform 12 b. In some cases, the terminal device that is handed off from second base station 24 to first base station 14b may desire to access some second data, such as data #1, from first edge computing platform 12 b. However, under the conventional method, the first edge computing platform 12b may delete the data #1 due to insufficient storage space, so that the first edge computing platform 12b needs to spend other time and resources to retrieve the data #1 for the terminal device to access, thereby causing service delay and even generating errors.

After establishing the adjacency relation with the second edge computing platform 22 according to the foregoing embodiment, in the embodiment shown in fig. 7, when the first edge computing platform 12b determines to delete or replace some of the first data, the first edge computing platform 12b also determines according to the second access record. In one operation, the first edge computing platform 12b updates the corresponding first access count according to the second access count, for example. Referring to tables 1 and 2, data #1 and data #20 in tables 1 and 2 are duplicate data, so the first edge computing platform 12b sums the first access count and the second access count corresponding to data #1, for example, and replaces the original first access count of data #1 with the summed result. Similarly, the first edge computing platform 12b sums the first access count and the second access count corresponding to the data #20, for example, and replaces the original first access count of the data #20 with the summed result. In accordance with the above, table 2 is updated, for example, as follows to table 3. Referring to table 3 below, the data #16 represents the minimum number of first accesses. Thus, the first edge computing platform 12b deletes data #16 instead of deleting data #1 as described above. In practice, the first edge computing platform 12b may continuously accumulate the statistical result based on the updated result (e.g., table 3), or the first edge computing platform 12b may continuously accumulate the statistical result based on each first access count (e.g., table 1) before the update.

TABLE 3

In another embodiment, the first edge computing platform 12b may also determine according to the higher of the first access count and the second access count. Taking table 3 as an example, since the second access count of the data #1 is higher than the first access count of the partial first data, the first edge computing platform 12b deletes the data #16 instead of the data # 1. The foregoing is exemplary only and is not intended as limiting.

Referring to fig. 8, fig. 8 is a flowchart illustrating a method of controlling a network communication system according to a sixth embodiment of the present invention. In this embodiment, the first access record records a first last access time of each first data, and the second access record records a second last access time of each second data. In the step of selectively deleting a portion of the first data according to the first access record and the second access record, the method further comprises the steps of: step S801, determining whether there is duplicate data in the first data and the second data by using a first edge computing platform; step S803, when the first edge computing platform determines that a first repeating data in the first data is the same as a second repeating data in the second data, the first edge computing platform compares a first last access time of the first repeating data with a second last access time of the second repeating data; step S805, when the first edge operation platform determines that the first last access time of the first duplicate data is earlier than the second last access time of the second duplicate data, the first edge operation platform replaces the first last access time of the first duplicate data with the second last access time of the second duplicate data to update the first last access time of the first duplicate data; in step S807, the first edge computing platform deletes the first duplicate data with the earliest first last access time.

Please refer to table 4 and table 5 below to illustrate this example. The following table 4 shows a plurality of first data and corresponding first last access times stored in the first edge computing platform 12b, and the following table 5 shows a plurality of second data and corresponding second last access times stored in the second edge computing platform 22. More specifically, the first edge stage 12b stores data #1, data #16 and data #20, and the second edge stage 22 stores data #1, data #4 and data # 20. The first edge computing platform 12b and the second edge computing platform 22 both store data #1 and data # 20.

TABLE 4

TABLE 5

With respect to the first edge computing platform 12b, in a conventional approach, the first edge computing platform 12b only considers the first last access time of each first data. Therefore, when the storage space of the first storage module of the first edge computing platform 12b is not enough, the first edge computing platform 12b may delete the first data with the earliest first last access time, that is, the longest data that is not accessed. With the information in table 4, the first edge computing platform 12b has deleted data #20 or replaced data #20 with new data. However, as shown in table 5, the second last access time corresponding to the data #20 is not the earliest of the respective second data, but is even later than the first last access time of the partial first data.

After establishing the adjacency relation with the second edge computing platform 22 according to the foregoing embodiment, in the embodiment shown in fig. 8, when the first edge computing platform 12b determines to delete or replace some of the first data, the first edge computing platform 12b also determines according to the second access record. In one operation, referring to tables 4 and 5, data #1 and data #20 in tables 4 and 5 are duplicate data, the first edge computing platform 12b determines, for example, a first last access time corresponding to data #1 and a second last access time corresponding to data #1, and the first edge computing platform 12b determines, for example, a first last access time corresponding to data #20 and a second last access time corresponding to data # 20. In this embodiment, the first last access time (20:53) corresponding to data #1 is no earlier than the second last access time (20:48) corresponding to data #1, and thus, the first edge computing platform 12b retains the first last access time corresponding to data # 1. On the other hand, the first last access time (20:20) corresponding to the data #20 is earlier than the second last access time (20:33) corresponding to the data #20, and thus the first edge computing platform 12b replaces the first last access time corresponding to the data #20 with the second last access time (20:33) corresponding to the data #20 to update the first last access time corresponding to the data # 20. In response to this, the first edge computing platform 12b updates table 4 to table 6, for example. As shown in Table 6, data #16 has the earliest last access time, which means that data #16 is not accessed for the longest time, and the first edge computing platform 12b deletes data #16 to make the storage space free.

TABLE 6

Under the advanced communication architecture, the network communication system further has a self organizing network server (SON server), for example, and the relevant details can refer to the relevant standard specifications of 3GPP in 3G and LTE, which are not described herein again. The self-organizing network server can be used to adjust handover parameters of the base station, such as parameters commonly known in the art as a3 offset or ttt (time to trigger), but not limited thereto. However, conventionally, the self-organizing network server only adjusts the handover parameters according to the signal strength between the terminal device and the base station, and fails to further improve the performance of the entire system. Fig. 9 is a flowchart of a method of a part of steps of a control method of a network communication system according to a seventh embodiment of the present invention, and fig. 10 is a functional framework diagram of the network communication system according to the seventh embodiment of the present invention. As shown in fig. 10, the network communication system further has, for example, an ad hoc network server 19 c. The self-organizing network server 19c is configured to communicatively couple to the first edge computing platform 12 c. After the step of providing the first platform identification information to the second edge computing platform, the method for controlling a network communication system further includes the following steps. In step S901, the second edge computing platform 22 provides second load information to the first edge computing platform 12c, where the second load information is related to a load of at least one second processor or a load of at least one second memory of the second edge computing platform 22. In step S903, the first edge computing platform provides the second load information to the self-organizing network server. In step S905, the self-organizing network server adjusts at least one handover parameter of the first base station according to the first load information and the second load information.

Referring to fig. 11, fig. 11 is a schematic diagram illustrating a terminal device switching according to an embodiment of the present invention. In fig. 11, a first edge computing platform 12c, a second edge computing platform 22a, a second edge computing platform 22b, a first base station 14c, a second base station 24a, and a second base station 24b are illustrated. The first edge computing platform 12c is communicatively coupled to the first base station 14c, the second edge computing platform 22a is communicatively coupled to the second base station 24a, and the second edge computing platform 22b is communicatively coupled to the second base station 24 b. Fig. 11 shows regions R1 and R2. The region R1 is a region where the communication range of the first base station 14c overlaps the communication range of the second base station 24a and also overlaps the communication range of the second base station 24b, and the region R2 is a region where the communication range of the first base station 14c overlaps the communication ranges of other base stations. In this embodiment, since the communication range of the second base station 24a and the communication range of the second base station 24b both overlap with the communication range of the first base station 14c, the second edge computing platform 22a and the second edge computing platform 22b are both defined as the neighbors of the first edge computing platform 12c, and the details thereof are not repeated herein as described in the other embodiments above.

Normally, when the terminal device 30 moves from the region R2 to the region R1, the self-organizing network server 19c adjusts the handover parameters of the first base station 14c according to the signal strength between the terminal device 30 and each base station. That is, the terminal device 30 is switched to the base station with the strongest signal strength with the terminal device 30 among the base stations. However, each base station may also communicate with other terminal devices, i.e. the first edge computing platform 12c, the second edge computing platform 22a and the second edge computing platform 22b may provide services to other terminal devices at the same time. For a hypothetical scenario where the signal strength between the second base station 24a and the terminal device 30 may be the strongest, the second edge computing platform 22a serves more terminal devices, and the workload of the second edge computing platform 22a is relatively heavy. In this case, if the terminal device 30 is handed over to the second base station 24a, the second edge computing platform 22a may not provide the terminal device 30 with a good enough service, and may even cause a delay that the user cannot receive.

In the embodiments shown in fig. 9 and 10, the self-organizing network server 19c further adjusts the handover parameters according to the load information of each base station, so as to consider the quality of service that each edge computing platform can provide to the terminal device 30, in addition to the signal strength between the terminal device 30 and each base station. The load information is, for example, a memory load, a processor load, or a network traffic (network traffic) of each edge computing platform. Based on the diversification of hardware specifications, the specific forms of the load information and the handover parameters are not limited herein, and all the methods for adjusting the handover parameters of the base station according to the load condition of the edge computing platform belong to the protection scope covered by the present invention.

In view of the above, the present invention further provides an edge calculation device, please refer to fig. 12 and 13 for description, fig. 12 is a functional block diagram of the edge calculation device according to an embodiment of the present invention, and fig. 13 is a system block diagram of the edge calculation device according to an embodiment of the present invention.

The memory 44 stores a plurality of instructions. The edge computing device 40 is configured to run an edge computing platform when the processor 42 executes instructions stored in the memory 44. The edge computing platform is at least used for executing the corresponding steps in the embodiments. As shown in fig. 12, the edge computing device 40 further has a storage module 46, for example. The storage module 46 is used for storing the first data and the access record thereof or other parameter data. The storage module 46 is, for example, a Hard Disk Drive (HDD) or a Solid State Drive (SSD), but not limited thereto.

As shown in fig. 13, the edge computing device 40 runs, for example, a virtual machine system 410(virtual machine system). In this embodiment, the edge computing platform 12 runs on a virtual machine system 410. In another embodiment, the virtual machine system 410 may also operate with the bs network management system 16 and the self-organizing network server 19. In another embodiment, the edge computing device 40 runs a plurality of virtual machine systems, and the edge computing platform 12, the bs network management system 16 and the self-organizing network server 19 run in different virtual machine systems respectively. Therefore, for the components in fig. 10, the first edge computing platform 12c, the bs network management system 16c and the self-organizing network server 19c can be integrated into the same physical machine (e.g. the edge computing device 40).

In one embodiment, the edge computing device 40 is configured to communicatively couple the base station network management server and the first base station. The edge computing platform 12 operated by the edge computing device 40 is configured to perform the following steps: obtaining base station identification information of a second base station from a base station network management server, wherein a second communication range of the second base station is overlapped with a partial first communication range of a first base station; generating platform adjacent information, wherein the platform adjacent information comprises platform identification information of the edge operation platform and base station identification information of a second base station; and providing platform adjacent information to the central control server so as to provide the platform adjacent information to the other edge operation platform in communication connection with the central control server through the central control server, wherein the platform adjacent information comprises base station identification information of the second base station.

When the processor executes the instructions, the edge computing platform 12 operated by the edge computing device 40 is configured to perform the following steps: the edge computing platform 12 establishes an adjacent relationship with another edge computing platform according to the confirmation signal provided by the other edge computing platform. When the remaining storage space of the storage module 46 is smaller than the predetermined size, the edge computing platform 12 communicates with another edge computing platform to determine whether each of the first data is the same as one of the second data; when the edge computing platform 12 determines that one of the first data is the same as one of the second data, the edge computing platform 12 selectively deletes a portion of the first data according to the first access record and the second access record.
