Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Exemplary embodiments of the present disclosure first provide an information service system based on a 5G network. Taking an application scenario in which a user device switches from a tracking area of an airport to a tracking area of an airplane as an example, fig. 1 shows a schematic system architecture of an operation environment of the present exemplary embodiment, and referring to fig. 1, the system 100 may include a user device 110, a first edge computing service 120, a service synchronization node 130, and a second edge computing service 140. The user device 110 may be a tablet computer or a personal computer used by a user, the first edge computing service 120 is an edge computing service corresponding to the first tracking area 121, for example, a first MEC (Mobile Edge Computing, edge computing) node, the service synchronization node 120 may be a server for synchronizing network service information (such as user identification information and resource usage progress information) in the first tracking area and the second tracking area, and the second edge computing service 140 is an edge computing service corresponding to the second tracking area 141, for example, a second MEC node, and the first edge computing service and the second edge computing service may be used to provide services required by the user and cloud computing functions nearby.
Based on the above description, the system in the present exemplary embodiment can be applied to the 5G network-based information service system shown in fig. 1.
For further explanation of the present exemplary embodiment with reference to fig. 2, as shown in fig. 2, the network service system 200 may include:
the first edge computing service 210 is configured to provide a network service for the user equipment 240 in response to a first service request transmitted by the user equipment 240 located in the first tracking area, and transmit identification information of the user equipment 240 and status information of the network service to the service synchronization node.
The user device in the present exemplary embodiment refers to an electronic device, such as a smart phone, a tablet computer, a notebook computer, or the like, which is used by a user and is capable of providing a specific network function or network service to the user. The network service refers to a specific service provided by a network and associated with an address location, and specifically may include a video service, for example, a service that a movie platform provides movies, a television play, or a social platform provides short videos or other video streaming play, etc.; audio services such as a service for a music platform to provide music play, etc. may also be included; still alternatively, the network service may be a cloud game service or the like.
The tracking area is a new concept set by network systems such as LTE for location management of user equipment, and the function of the tracking area is to implement location management of the user equipment, and may be defined as one or more continuous cells, where each tracking area has its own unique TAI (Tracking Area Identity, tracking area identifier), and the tracking areas cannot overlap with each other. The plurality of tracking areas can form a tracking area list, the core network distributes the tracking area list to one user equipment, and when the user equipment is in an idle state, the core network can know the tracking area where the user equipment is located, and then can know the position where the user equipment is located; when the user equipment in the idle state needs to be paged, paging is performed in all cells of the tracking area allocated by the user equipment.
The first tracking area may refer to an initial tracking area of the user equipment, or a current tracking area, or a tracking area to be entered, and may be specifically determined according to an actual application scenario. When the user equipment is located in the first tracking area, the user equipment sends a first service request to the first edge computing service, wherein the service request refers to request information that a user needs to access a specific network resource, for example, access to play a certain video or audio, and the like, and the service request can be simple notification information for notifying the first edge computing service that the user equipment needs to access the resource; notification information including data such as a user equipment identifier, a request time, or a request content may be used. When the first edge computing service receives the first service request sent by the user equipment, the first edge computing service can respond to the first service request and provide corresponding network services for the user equipment, for example, provide network services such as playing video, audio, video, music and the like for the user at an airport or on an airplane.
In this exemplary embodiment, after the first edge computing service provides the network service for the user, the identification information of the user equipment and the state information of the network service may be sent to the service synchronization node, so that the service synchronization node ensures that the user equipment can still perform continuous network service after performing tracking area switching.
The service synchronization node 220 is configured to receive the status information, and to send the identification information and the status information of the user equipment 240 to the second edge computing service in response to the synchronization request sent by the second edge computing service.
When a user performs a network service, some information is usually generated, for example, what account number or identifier is used by the user equipment to log in what service platform, what content is browsed, or time of performing the network service, for example, an account ID (Identify) of a user logging in a movie application program, a movie name or movie ID of the user, a browsing website, a viewing time, a playing or pausing number, an initial viewing time, and change information of a timestamp in the viewing process, etc., where the identity of the user equipment can be reflected as user identification information, for example, the present exemplary embodiment can be used as identification information of the user by IMEI (International Mobile Equipment Identity, international mobile equipment identification code) +android ID (Android unique identifier) +serial Serial interface) +uuid (Universally Unique Identifier, universal unique identifier); while other information, such as information reflecting the progress of resource usage, may be used as status information of the network service, such as time stamp information.
The service synchronization node may be a preset independent database, or may be a database corresponding to the first edge computing service and capable of being synchronously updated with a database corresponding to the second edge computing service. The method can record the identification information of the user equipment and the state information of the network service of the user in the first edge computing service, and can also receive a synchronous request sent by the second edge computing service, so that the second edge computing service reads the identification information of the user equipment and the state information of the network service.
The service synchronization node may receive the identification information and the status information of the user equipment sent by the first edge computing service, and send the identification information and the status information of the user equipment to the second edge computing service, so as to ensure that the network service provided for the user equipment based on the first edge computing service can provide the continuity service for the user in the second tracking area.
A second edge computing service 230 configured to send a synchronization request to the service synchronization node in response to a second service request sent after the user equipment 240 enters the second tracking area, and to continue providing network services for the user equipment 240 according to the received identification information and status information of the user equipment 240;
The first service request and the second service request are access requests for the target resource.
When the user equipment enters a new tracking area that is not in its assigned tracking area list, it will find that the TAC (Tracking area code ) of the new tracking area is not in its assigned tracking area list, and a TAU (Tracking area Update ) is required. At this time, the ue sends a tracking area update request to the network side. In this exemplary embodiment, the network side may receive a tracking area update request sent by the ue, and return feedback information about the tracking area update accept to the ue, so that the ue updates from the first tracking area to the second tracking area, thereby completing the TAU procedure. For example, the user equipment switches from the tracking area of the airport to the tracking area on the aircraft, the tracking area of the airport is the first tracking area, and the tracking area on the aircraft is the second tracking area. It should be noted that "first" and "second" in the first tracking area and the second tracking area in the present exemplary embodiment are only distinctive expressions, for example, the first tracking area is an initial service area of the user equipment, the first edge computing service is an edge computing service in the initial service area, the second tracking area is a service area adjacent to the initial service area, the second edge computing service is an edge computing service of the service area, and the disclosure is not limited in particular. Generally, the second tracking area may have an association relationship with the first tracking area, for example, the second tracking area is a tracking area adjacent to the first tracking area, or a preset group of associated tracking areas, and when it is determined that the user equipment leaves the first tracking area and enters the second tracking area associated with the first tracking area, continuity is ensured for providing network services that are not completed by the user equipment in the first tracking area.
After entering the second tracking area, the user equipment may send a second service request to the second edge computing service, where the second service request and the first service request are access requests for target resources, in other words, the first service request and the resources of the network service for which the second service request are the same, for example, when the user is in the first tracking area, the user sends the first service request to the first edge computing service, and requests to open the a video, and a part of the a video is watched; when the user is in the second tracking area, the service request that requests to open the a video again or still continuously requests to watch the a video may be regarded as a second service request, otherwise, the service request sent in the second tracking area does not belong to the second service request corresponding to the first service request, and may be regarded as a new service request, for example, a request to play the B video that is not watched while in the first tracking area.
After receiving the second service request sent by the user equipment, the second edge computing service may send a synchronization request to the service synchronization node, where the synchronization request refers to a request for reading the identification information of the user equipment synchronized by the first edge computing service and the state information of the network service, and after receiving the synchronization request, the service synchronization node may return the identification information and the state information of the user equipment to the second edge computing service, where the second edge computing service may continuously provide the corresponding network service for the user equipment according to the received identification information and the state information of the user equipment, for example, determine the breakpoint position, the timestamp, and other state information of the video played by the user equipment in the first tracking area, and enable the user equipment to play the video in the breakpoint of the second tracking area according to the identification information and the state information of the user equipment, thereby ensuring that the user equipment can still perform continuous network service after being changed from the first tracking area to the second tracking area.
In this exemplary embodiment, when the user equipment enters the second tracking area and triggers the second edge computing service to provide the continuous network service, the user equipment may perform the migration application of the network breakpoint service through the user identifier, for example, when the user views the video through the mobile phone in the first tracking area of the airport and moves to the second tracking area corresponding to the airplane, the user equipment may view the video through the original mobile phone, or may also use other user equipment, for example, a tablet computer or an audio-video system on the airplane to view the breakpoint video, and so on.
It should be noted that, the first edge computing service and the second edge computing service may be MEC devices corresponding to different tracking areas, for example, MEC devices in an airport may be the first edge computing service, and MEC devices in an airplane may be the second edge computing service. The MEC equipment can provide services and cloud computing functions required by users nearby by utilizing a wireless access network, so that a carrier-class service environment with high performance, low delay and high bandwidth is created, and an access request sent by the user equipment can be received and sent to a corresponding network.
The MEC technology can enable the traditional wireless access network to have the conditions of service localization and close-range deployment, so that the wireless access network has the transmission capability of low time delay and high bandwidth, and the requirement of the mobile network on the transmission bandwidth and the time delay is effectively relieved. Meanwhile, the service face sinking localization deployment can effectively reduce the network load and the requirement on the network backhaul bandwidth, thereby achieving the purpose of reducing the network operation cost. In addition, the localization deployment of the service application enables the service application to be closer to the wireless network and the user, and the perception and utilization of network context information (position, network load, wireless resource utilization rate and the like) are easier to realize, so that the service experience of the user can be effectively improved.
It should be noted that, the MEC apparatus in the present exemplary embodiment is not limited to the apparatus form described above, and may also be referred to as a MEC platform, a MEC system, a MEC node, or others, which is not specifically limited in this disclosure.
Based on the above description, in the present exemplary embodiment, the network service system includes a first edge calculation service configured to provide a network service for a user equipment in response to a first service request transmitted by the user equipment located in a first tracking area, and transmit identification information of the user equipment and status information of the network service to a service synchronization node; the service synchronization node is configured to receive the state information, and respond to the synchronization request sent by the second edge computing service to send the identification information and the state information of the user equipment to the second edge computing service; the second edge computing service is configured to respond to a second service request sent after the user equipment enters the second tracking area, send a synchronization request to the service synchronization node, and continue to provide network service for the user equipment according to the received identification information and state information of the user equipment; the first service request and the second service request are access requests for the target resource. On the one hand, the present exemplary embodiment proposes a new system architecture of information service based on a 5G network, where when a first edge computing service provides network service for a user device in a first tracking area, the service synchronization node may synchronously record identification information of the user device and status information of the network service of the user device in the first tracking area, and when the user device switches to a second tracking area, the identification information and the status information may be read, and according to the status information of the identification information, the network service may be continuously provided for the user device, so that it is ensured that the user device may still enjoy continuous network service after performing area update, and user experience is improved; on the other hand, according to the embodiment of the invention, through interaction between the first edge computing service corresponding to the first tracking area, the second edge computing service corresponding to the second tracking area and the service synchronization node, the breakpoint service of the network service can be provided after the user equipment performs area update, and the process is not perceived by the user, so that the network service efficiency and the accuracy of the breakpoint service are higher.
The present exemplary embodiment also provides an information service method based on a 5G network, which may be applied to a service synchronization node, as shown in fig. 3, and specifically may include the following steps S310 to S320:
step S310, receiving the identification information and the state information of the user equipment sent by the first edge computing service, wherein the state information is the state information of the first edge computing service providing network service for the user equipment located in the first tracking area;
step S320, in response to the synchronization request sent by the second edge computing service, the identification information and the status information of the user equipment are sent to the second edge computing service, so that the second edge computing service continues to provide network services for the user equipment entering the second tracking area according to the identification information and the status information of the user equipment.
In practical applications, when a user performs a network service, some information is usually generated, for example, what account number is used by the user equipment or what service platform is logged in, what content is browsed, or time of performing the network service, for example, an account ID (identity) of a user logging in a movie application, a movie name or movie ID of the user, a browsing website, a viewing time, a number of play or pause times, a starting viewing time, and change information of a timestamp in a viewing process, where the user identity can be reflected, for example, the user identity information can be identified by a data structure of imei+android id+serial+uuid in the present exemplary embodiment, and in addition, the user identity information can also be represented by other data structures, which is not limited in the present disclosure; while other information, such as information reflecting the progress of resource usage, may be used as status information of the network service, such as time stamp information. In this exemplary embodiment, the first edge computing service may automatically acquire the state information of the user equipment, and may record various state information by means of user triggering or the like if necessary.
The service synchronization node may synchronously record identification information and status information of the user equipment transmitted by the first edge computing service after the first edge computing service provides the network service for the user equipment, so as to determine a status and progress of the network service performed by the user equipment in the first tracking area. The service synchronization node may be a preset independent database, or may be a database corresponding to the first edge computing service and capable of being synchronously updated with a database corresponding to the second edge computing service.
The service synchronization node may receive the user equipment identification information and the status information sent by the first edge computing service, and return the identification information and the status information to the second edge computing service when receiving the synchronization request sent by the second edge computing service, so that the second edge computing service can provide a continuous service for the user equipment entering the second tracking area according to the representation information and the status information.

In one aspect of the present exemplary embodiment, the service synchronization node synchronously updates the identification information of the user equipment and the state information of the network service to the second tracking area, so that the second edge computing service can provide continuous network service for the user equipment based on the identification information of the user equipment and the state information of the network service; on the other hand, through the process of providing continuous network service for the user by the service synchronization node, the user has no perception, and good network service experience is provided for the user.
The present exemplary embodiment also provides a 5G network-based information service method, which may be applied to a second edge computing service, as shown in fig. 4, and specifically may include the following steps S410 to S430:
step S410, in response to a second service request sent after the user equipment enters the second tracking area, sending a synchronization request to the service synchronization node, where the second service request is used to request access to the target resource.
When the user equipment enters a new tracking area that is not in its assigned tracking area list, it will find that the TAC of the new tracking area is not in its assigned tracking area list, and a TAU is needed. At this time, the ue sends a tracking area update request to the network side. In this exemplary embodiment, the network side may receive a tracking area update request sent by the ue, and return feedback information about the tracking area update accept to the ue, so that the ue updates from the first tracking area to the second tracking area, thereby completing the TAU procedure. For example, the user equipment switches from the tracking area of the airport to the tracking area on the aircraft, the tracking area of the airport is the first tracking area, and the tracking area on the aircraft is the second tracking area.
After entering the second tracking area, the ue may send a second service request to the second edge computing service, where the second service request is similar to the first service request, and also refers to request information that the user needs to access a specific network resource, for example, access to play a certain video or audio, which may be simple notification information notifying the second edge computing service that the ue needs to access the resource; notification information including data such as a user equipment identifier, a request time, or a request content may be used.
It should be noted that, the second service request and the first service request are access requests for the target resource, in other words, the resources of the network service for which the first service request and the second service request are the same, for example, when the user is in the first tracking area, the first service request is sent to the first edge computing service, and the request is made to open the a video, so as to view a part of the a video; when the user is in the second tracking area, the service request that requests to open the a video again or still continuously requests to watch the a video may be regarded as a second service request, otherwise, the service request sent in the second tracking area does not belong to the second service request corresponding to the first service request, and may be regarded as a new service request, for example, a request to play the B video that is not watched while in the first tracking area.
Step S420, receiving the identification information of the user equipment and the state information of the network service fed back by the service synchronization node according to the synchronization request, wherein the state information is the state information of the network service for providing the user equipment with the access target resource by the first edge computing service when the user equipment is in the first tracking area.

On the one hand, the second tracking area can acquire the identification information of the user equipment and the state information of the network service accessing the target resource in the first tracking area by sending a synchronization request to the service synchronization node, so that the current user can access the breakpoint of the target resource in the second tracking area, and the continuity of the network service is ensured; on the other hand, the process of providing continuous network service for the user is not perceived by the user, and the user has better network service experience.
In an exemplary embodiment, the status information is usage progress information of the target resource, such as a start time, a pause time, a breakpoint time, a time corresponding to a key frame, a time stamp of a video that has been watched, and the like.
Further, the step S430 may include:
and sending the data stream of the non-accessed part of the user equipment in the target resource to the user equipment according to the identification information and the use progress information of the user equipment.
The data stream of the non-accessed portion may be video data or audio data that has not yet been played, for example, when the user views the movie to half of the content in the first tracking area and switches the tracking area, the second half of the content of the movie may be used as the data stream of the non-accessed portion. According to the identification information of the user equipment and the use progress information of the target resource, the second edge computing service can accurately and effectively provide corresponding breakpoint network services from the node actually required by the user.
In an exemplary embodiment, after the user equipment enters the second tracking area and sends the second service request, the network service providing method may further include:
And enabling the user equipment to trigger the insertion flow of the first uplink classifier ULCL so as to send a synchronization request to the service synchronization node.
