Detailed Description
The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the embodiments described are only some embodiments of the present disclosure, rather than all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The relative arrangement of parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.
Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as exemplary only and not as limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
The inventors of the present disclosure have noted that the goal of the immigration fusion is to efficiently provide a consistent, better business experience for users.
"high efficiency" includes two connotations: firstly, the integration of network architecture and functions is required, and the behavior of a user in different networks is uniformly controlled and managed by the integrated core network function instead of being realized by complex core network interoperation; and the second is that the sharing of physical facilities including transmission resources, machine room resources, virtualized infrastructure resources and the like is required, so that the network construction and operation and maintenance costs of operators are saved.
A "consistent business experience" requires consistent network resources and consistent business resources. The consistent network resources refer to that the network resources which can be utilized when a user initiates a service in a network are the same, and comprise air interface resources, backhaul resources and the like; the consistent service resource refers to that when a user initiates a service in different networks, the service resources that can be accessed are the same, for example, the same CDN (Content Delivery Network) resource can be accessed.
The requirement of better service experience is that the converged network supports multi-connection aggregation, traffic grooming and lossless switching, and the network can select an optimal network transmission scheme for the user/service according to the characteristics of the user/service, so that the system capacity is improved, the network performance is optimized, and the user experience is improved.
If the core networks of the fixed network and the mobile network realize the integration of functions and architectures and the integrated core network supports multi-connection, consistent and better service experience can be ensured.
In order to effectively meet the requirements of future networks such as high bandwidth requirements, low latency and high reliability, and large-scale MTC (Machine type Communication) terminal connections, a Mobile Edge Computing (MEC) concept has been proposed and has gained wide attention in the academic and industrial fields, and at present, the MEC concept has been aimed at 3GPP Mobile networks from the beginning of the project, extended to support non-3 GPP networks (WiFi, wired networks, etc.), and its name has been modified from Mobile Edge Computing to Multi-Access Edge Computing (MEC). The multi-access edge computing enables localized, close-range, and distributed deployment of applications, services, and content by migrating computing storage capacity and business service capacity to the network edge. Meanwhile, the MEC fully excavates network data and information, realizes the perception and analysis of network context information and opens the information to a third party service application, and promotes the deep fusion of the network and the service. Consequently, MEC becomes one of the key technologies of future 5G networks
The multi-access edge computing technology provides a new possibility for solving multi-network cooperation oriented to the fixed-mobile convergence. Firstly, the multi-access edge calculation supports various different access technologies, and provides a multi-network cooperative basic platform; secondly, in order to support the MEC, the 5G network realizes functions of distributed subsidence deployment, flexible routing and the like of a user plane, and the mobile core network presents a distributed gateway architecture similar to that of a fixed network for the first time, so that the flexible path selection of the service in a multi-network environment has more freedom, and the fixed network can comprehensively consider infrastructure resources (such as machine rooms, transmission and the like) during deployment construction and lay a foundation for the evolution of a future fusion core network; furthermore, the multi-access edge computing can open and dynamically acquire network state information through network capacity, and customize an optimal network transmission scheme according to the requirements of users/services; in addition, the multi-access edge computing provides cloud computing capability and an IT service environment at the network edge, which may provide more possibilities for multi-network cooperation, for example, a multi-access management service (a service with multi-link management capability, such as an MPTCP protocol, etc.) or a CDN service (providing a unified CDN service for multi-network users) may be deployed on a platform to achieve consistency of a fixed-mobile network on network resources and service resources.
Fig. 1 is an exemplary flowchart of a multiple access edge calculation method according to an embodiment of the present disclosure. In some embodiments, the method steps of the present embodiment may be performed by a multi-access edge computing platform.
In step 101, after receiving a service request sent by a user terminal through a mobile network, an IP address of an application server is extracted from the service request.
In step 102, a query is made as to whether there is a offload policy associated with the IP address.
In step 103, in the presence of a offloading policy associated with the IP address, the data flow corresponding to the IP address is offloaded to the fixed network.
In some embodiments, the data flow corresponding to the IP address is transmitted over the mobile network in the absence of a offload policy associated with the IP address.
In the multi-access edge calculation method provided by the above embodiment of the present disclosure, according to the offloading policy associated with the IP address of the application server, the corresponding data stream is offloaded to the fixed network. The resources of each network can be fully utilized through service shunting, and the service experience of a user is improved.
Fig. 2 is an exemplary flowchart of a multiple access edge calculation method according to another embodiment of the disclosure. In some embodiments, the method steps of the present embodiment may be performed by a multi-access edge computing platform.
In step 201, after receiving a domain name resolution request sent by a user terminal through a mobile network, extracting a domain name requested to be resolved from the domain name resolution request.
At step 202, it is determined whether the domain name is included in the offload list.
If the domain name is included in the offload list, go to step 203; if the domain name is not included in the offload list, then step 206 is performed.
In step 203, the domain name resolution request is sent to the fixed network domain name server for domain name resolution.
In step 204, after receiving a first domain name resolution response sent by the fixed network domain name server, sending the first domain name resolution response to the user terminal, where the first domain name resolution response includes a first IP address of the relevant application server.
At step 205, a breakout policy associated with the first IP address is generated.
In step 206, the domain name resolution request is sent to the mobile network domain name server for domain name resolution.
In step 207, after receiving a second domain name resolution response sent by the mobile network domain name server, sending the second domain name resolution response to the user terminal, where the second domain name resolution response includes a second IP address of the relevant application server.
In the above embodiment, if the domain name requested to be resolved by the user is included in the offload list, the domain name resolution of the fixed network domain name server is performed to obtain the first IP address of the corresponding application server in the fixed network, so that the user terminal accesses the relevant application server by using the first IP address, thereby implementing traffic offload from the mobile network to the fixed network. If the domain name requested to be resolved by the user is not included in the uninstalling list, the domain name resolution of the domain name server of the mobile network is used to obtain a second IP address of the corresponding application server in the mobile network, so that the user terminal can access the relevant application server by using the second IP address, and in this case, service shunting is not needed.
For example, the offload list includes domain names corresponding to all service applications that the operator desires to perform traffic offload, such as high-throughput video service applications like kuku, lovely art, and the like. Because the service flow corresponding to the domain names is large, the user experience can be improved through service shunting. For other service applications with low throughput, the traffic flow is low, and the offloading process is not needed, so that the traffic is directly transmitted through the mobile network in this case.
Fig. 3 is an exemplary block diagram of a multiple access edge computing platform of one embodiment of the present disclosure. As shown in fig. 3, the multi-access edge computing platform includes a user plane function module 31 and a routing rule control module 32.

The routing rule control module 32 is configured to have a breakout policy associated with the IP address.
In some embodiments, the user plane function module 31 is further configured to transmit the data stream corresponding to the IP address through the mobile network in the absence of the offloading policy associated with the IP address.
In the multi-access edge computing platform provided in the above embodiments of the present disclosure, according to a offloading policy associated with an IP address of an application server, a corresponding data flow is offloaded to a fixed network. The resources of each network can be fully utilized through service shunting, and the service experience of a user is improved.

The mobile traffic offload module 33 is configured to, after the user plane function module 31 receives a domain name resolution request sent by the user terminal through the mobile network, extract a domain name requested to be resolved from the domain name resolution request, and determine whether the domain name is included in the offload list.

In some embodiments, the mobile traffic offload module 33 is further configured to send a domain name resolution request to the mobile network domain name server for domain name resolution if the domain name is not included in the offload list, and send a second domain name resolution response to the user terminal after receiving a second domain name resolution response sent by the mobile network domain name server, where the second domain name resolution response includes the second IP address of the relevant application server.

If the domain name requested to be resolved by the user is not included in the uninstalling list, the domain name resolution of the domain name server of the mobile network is used to obtain a second IP address of the corresponding application server in the mobile network, so that the user terminal can access the relevant application server by using the second IP address, and in this case, service shunting is not needed.
