Description

[0001] A METHOD AND A DEVICE TO ENABLE EFFICIENT COMMUNICATION BETWEEN

[0002] MEC SYSTEMS

[0003] FIELD OF THE INVENTION

[0004] The present invention relates to a method and a device to enable communication between different MEC systems in the wireless network.

[0005] BACKGROUND OF THE INVENTION

[0006] In the wireless communication network, there are different MEC (Multi-access Edge Computing) systems providing wireless signalling for the user devices (such as mobile phones, loT devices, GPS devices etc.) to ensure uninterrupted communication of the user devices and to provide continuous service to the user devices. Each MEC system comprises more than one MEC host in connection with a communication and service provider (such as base station, wireless modem etc.) as a group and each of which comprises MEC platforms, MEC applications, MEC services etc. Since each communication and service provider has a limited coverage area and the MEC host of that communication and service provider can just provide service within this limited coverage area, the MEC hosts within the same MEC system are inter-connected to each other to exchange data for ensuring continuous data transmission to user devices. Furthermore, since the MEC hosts that are within different MEC systems are not inter-connected directly, to ensure continuous communication / service, these different MEC systems are also inter-connected to each other (which is called as federation of the MEC systems). For instance, when a user device getting service from a MEC host of a first communication and service provider within a first MEC system gets out from the coverage area of the first communication and service provider and enters the coverage area of a second communication and service provider which is in connection with a different MEC host not within the first MEC system and within a second MEC system, by exchanging data between these two MEC systems, the user device is able to continue to get service from the MEC host of the second communication and service provider. In such a case, the service that is being gotten from the MEC host of the first communication and service provider can also be a service that is present in the MEC host of the second communication and service provider or a service that is not present in the MEC host of the second communication and service provider. If it is present, by sharing of the service information between the MEC hosts, user device directly gets service from the MEC host of the second communication and service provider but, if it is not present, then the MEC host of the first communication and service provider continues to provide service to the user device over the MEC host of the second communication and service provider by sending the data of the service. Furthermore, each MEC system further comprises a MEC orchestrator which is ensuring the connection of the MEC hosts within the same MEC system.

[0007] In the wireless network, there are MEC federators each of which is associated with a MEC system via the MEC orchestrator of that MEC system and which are inter-connected to each other to exchange data. By data exchange, each MEC federator informs the others about the services associated MEC system can provide. In this network architecture, when a user device requires a service from a MEC host within a MEC system, first it is checked in the MEC system that that MEC host has the capability of providing the requested service or not. If that MEC host has the capability, then the service is provided from that MEC host. If that MEC host has not the capability, then a response from that MEC host is provided to inform that it has not the capability. Following this response, the service request is transmitted to the MEC orchestrator of the same MEC system to check whether there is any other MEC host within the same MEC system that has the capability of providing the requested service or not. If it is found that there is another MEC host within the same MEC system having the capability to provide service, then the service is provided from that MEC host. If it is not found that there is another MEC host within the same MEC system having the capability to provide service, then a response from the MEC orchestrator is provided to inform that there is no MEC host that has the capability to provide requested service. Following this response, the service request is transmitted to the MEC federator of the same MEC system to find any other MEC systems that has other MEC hosts having the capability of providing the requested service by checking the MEC federations associated with these MEC systems. When the other MEC systems that have other MEC hosts having the capability of providing the requested service are found, then the information of these MEC systems obtained from their MEC federations are provided to the MEC federation, associated with the MEC system having the MEC host from which the service is requested, for deciding the MEC system, through which the service will be gotten, among the found MEC systems. Then the decision is transmitted to the MEC host from which the service is requested and to the decided MEC system to ensure data exchange between these MEC systems through related MEC federators. Then the requested service is performed by the decided MEC system and provided to the user device over the MEC host from which the service is requested by these inter-connections.

[0008] Although this inter-connecting architecture and data exchange ensure continuous communication / service, since there are too much steps, this reveals too much latency and also requires too much operations and power consumption. As explained above, the signalling steps included in the standard signalling are long and complex. The traffic that will occur due to the increasing number of users and applications day by day will also increase the signalling load and complexity. In addition, when requests are made to other MEC systems for the service to be used, information is returned by more than one MEC system and the MEC system requiring service is expected to make a choice. At this point, signalling overhead occurs during service discovery due to the increasing number of users and applications day by day. Additionally, since the MEC system requiring service should make the selection of another MEC system itself, optimization problems may occur.

[0009] Therefore, all the problems mentioned above have made it necessary to make an innovation in the relevant technical field as a result.

[0040] DESCRIPTION OF THE INVENTION

[0041] In the wireless communication network, there are different MEC (Multi-access Edge Computing) systems providing wireless signalling for the user devices (such as mobile phones, loT devices, GPS devices etc.) to ensure uninterrupted communication of the user devices and to provide continuous service to the user devices. Each MEC system comprises a group of MEC hosts each of which is in connection with a communication and service provider (such as base station, wireless modem etc.) each of which comprises MEC platforms, MEC applications, MEC services etc., and from which the user devices request services. Sometimes a requested service cannot be responded by the MEC system which has the MEC host to which the requested service is reached from the user device and accordingly this requested service can be provided by other MEC hosts of other MEC systems. For this, MEC systems are connected to each other by the associated MEC federators. Although this ensures uninterrupted communication / service, since there are too much operation and data exchange steps, this reveals too much latency and also requires too much operations and power consumption. In order to eliminate these, with the present invention, a method and a device to enable efficient communication between different MEC systems in the wireless network is developed.

[0048] In addition, the method of the present invention, an exemplary flow chart of which is given in figure 2, is configured for being used within a wireless communication network an exemplary embodiment of which is given in figure 1 and which comprises

[0049] • MEC hosts (2), each of which is in connection with a communication and service provider (such as base stations, wireless modems, core networks etc.) and from which user devices (6) (such as mobile phones, tablets, loT devices, GPS devices etc.) request services (the MEC host comprises MEC platforms, MEC applications, MEC services etc.),

[0050] • MEC systems (1 ) each of which has a group of MEC hosts (2), at least one MEC orchestrator (3) which connects the MEC hosts (2) of the same MEC system (1 ) to each other and which ensures data exchange between the MEC hosts (2) of the same MEC system (1 ), and at least one above-mentioned device (5) of the present invention,

[0052] The method is configured to ensure communication and data transmission between at least two MEC hosts (2) directly (not over the MEC federators (4)), which are not in the same MEC system (1 ), when a service requested from one MEC host (2) is not able to being provided by that MEC host (2) but is able to being provided by the other MEC host (2). The method comprises the steps of, • receipt of at least one service request from a user device (6) by a MEC host (2) through a communication and service provider, within a MEC system (1 ) having the device (5);

[0053] • checking, by the MEC host (2) itself, whether the MEC host (2) has the capability of providing the requested service or not;

[0054] • if not, sending the service request to the MEC orchestrator (3) of the MEC system (1 ) having the device (5) and the MEC host (2) from which the service is requested;

[0055] • checking the information within the database of the device (5) for getting information of the other MEC hosts (2) having the capability of providing the requested service;

[0056] • selecting, by the device (5), another MEC host (2) from the database that has the capability of providing the requested service;

[0057] • sending the information of the selected another MEC host (2) to the MEC host (2), which has received the requested service from the user device (6), from the device (5) over MEC orchestrator (3) in communication with the device (5);

[0058] • after receipt of the information of the selected another MEC host (2), starting data exchange between the MEC host (2) that has received the service request from the user device (6) and the selected another MEC host (2) for providing the requested service by the selected another MEC host (2) over the MEC host (2) that has received the service request from the user device (6).

[0059] The device (5) of the present invention is provided within the each MEC system (1 ), which is federated with the others in a wireless communication network through MEC federators (4), such that the device (5) provided in a MEC system (1 ) is in connection with the MEC orchestrator (3) of the same MEC system (1 ) and the MEC federator (4) associated with the same MEC system (1 ). The device (5) comprises a database having the information of the MEC services that are provided by the MEC hosts (2) in relation with the related MEC federator (4) information. These information are provided to the device (5) from the MEC federator (4) to which the device (5) is in connection with, periodically (for instance, during federation process of the MEC federators (4) with each other). An exemplary operation of the method and the device (5) of the present invention can be performed as follows. When a MEC service request is received from an application of a user device (6) through a communication and service provider by a first MEC host (2) within a first MEC system (1 ) having the device (5), the first MEC host (2) checks itself whether it has the capability of providing the requested service or not. If the first MEC host (2) does not have the capability, then the first MEC host (2) transmits the service request to the MEC orchestrator (3) of the first MEC system (1 ). Then the information within the database of the device (5) of the first MEC system (1 ) is checked and other MEC hosts (2) having the capability of providing the requested service is determined. After the determination, the device (5) selects a second MEC host (2) from the database among the other MEC hosts (2) having the capability of providing the requested service and sends the information of the second MEC host (2) to the first MEC host (2) over the MEC orchestrator (3) having the device (5). After receipt of the information of the second MEC host (2), direct data exchange between the first MEC host (2) and the second MEC host (2) is started for providing the requested service by the second MEC host (2) over the first MEC host (1 ) to the user device (6). Thanks to the device (5) and the method of the present invention, data exchange steps between MEC systems (1 ) when a requested service cannot be provided by a MEC system (1 ) is reduced. Accordingly, providing a service that is requested by a user device (6) is able to be performed much more quickly and therefore latency in the communication is able to be reduced. Therefore, by the present invention much more efficient and power saving method and device (5) is able to be ensured.

[0060] In a preferable embodiment of the method of the present invention, if it is determined that the MEC host (2) has the capability of providing the requested service, the requested service is provided by the same MEC host (2) itself.

[0061] In a preferable embodiment of the present invention, the database comprises the information of the services that are provided by the MEC hosts (2) which are within the MEC system (1 ), in which the MEC host (2) from which the service is requested is present, and within the other MEC systems (1 ) in the communication network. Yet in another preferable embodiment of the present invention, the database comprises the information of the services that are provided by the MEC hosts (2) which are only in the other MEC systems (1 ). In this embodiment, after the step of sending the service request to the MEC orchestrator (3) of the MEC system (1 ) having the MEC host (2) from which the service is requested, the method further comprises the steps of

[0062] • checking by the MEC orchestrator (3) of the MEC system (1 ), which has the MEC host (2) being received the service request, whether there is other MEC host (2) within the same MEC system (1 ) having the capability of providing the requested service or not,

[0063] • if yes, then transmitting the service request from the MEC host (2) that is received the service request from the user device (6) to the MEC host (2) found in the same MEC system (1 ) for providing the requested service by the found MEC host (2) over the MEC host (2) that has received the service request from the user device (6),

[0064] • if no, performing the steps from the step of “checking the information within the database”.

[0065] With this embodiment, it is firstly tried to provide the requested service by the MEC system

[0066] (1 ), having the MEC host (2) that is received the service request, itself. If there is no MEC host (2) within the MEC system (1 ) having the capability of providing the requested service, then any other MEC hosts (2) having capability of providing the requested service out of the MEC system (1 ) is searched. Therefore, latency for responding a service request can be reduced efficiently. In this embodiment, if it is determined that the requested service should be provided from any other MEC host (2) out of the MEC system (1 ), after selection of the another MEC host (2), data exchange between the selected another MEC host (2) and the MEC host (2), which has received the requested service from the user device (6), is performed by setting up a direct communication between the selected another MEC host

[0067] (2) and the MEC host (2) preferably over a Mpp-fed link.

[0068] In a preferable embodiment of the present invention, the information within the database is provided as a table, an exemplary of which is given below table - 1 .

[0069] Table - 1 Information provided within the database of the device

[0070] Preferably, the information of the provided services is given as Service ID, information of the MEC host (2) related with a service is given as MEC Platform ID, and information of the MEC federator (4) associated with a MEC system (1 ) having the MEC host (2) related with a service is given as Federation Manager ID. If the database has the information of the available service capacity of the MEC host (2) providing that service, then selection of a MEC host (2) among the MEC hosts (2) giving the same service is performed with respect to the available service capacities of the MEC hosts (2) such that the MEC host (2) having the much more available service capacity among the MEC hosts (2) giving the same service is selected. Therefore, the service can be given effectively.

[0071] Thanks to the method and the device (5) of the present invention, the signalling burden complexity is reduced, latency is decreased, and optimum power consumption can be ensured. Accordingly effective and efficient communication between the MEC systems (1 ) is able to be provided.
