The mobile edge system-level management part mainly includes three functional modules: mobile edge orchestrator (mobile edge orchestrator).
1) Mobile edge orchestrator
Mobile edge orchestrator is the core function of mobile edge system-level management and is mainly responsible for 5 functions:
Based on the deployed mobile host, the orchestrator can maintain and maintain the entire mobile system. Maintenance and maintenance content includes: available resources, available mobile edge services, network topology, etc.;
2) Loading APP data packages, including: checking the integrity and authenticity of the data packages, verifying APP rules and requirements, recording the loaded data packages, and preparing corresponding virtualization infrastructure management to process these APPs.
3Choose the appropriate mobile edge host for APP instances
ization, this process has certain constraints, such as: delay, available resources, available services, etc.
④Trigger APP instantiation and termination.
When the reset function is supported, the reset of the APP can be triggered. 2) Operation support system
The operation support system is generally the operator’s OSs.oss obtains requests through customer-facing services (CFS) and user equipment (UE) APPs, and is used to instantiate or terminate APPs. At the same time, Decisions and authorizations must also be made on these requests. Authorized requests will be submitted to the mobile edge orchestrator for further processing.
One thing to mention here is that if supported, OSS can also start from
Obtain the request from the UE’s APP for redeployment of the APP between the external cloud and the mobile edge system. LoRa gateway
3) User APP life cycle management agent
The user APP is a mobile edge APP, which is instantiated in the mobile edge system and responds to the user’s request through an APP running on the UE.
The user APP life cycle management agent allows the UE APP to request the loading, instantiation and termination of a user APP. It can also support the redeployment of the user APP inside or outside the mobile edge system. For the status of the user APP, it can also It can notify the UE’s APP. In addition, the user APP life cycle management agent authorizes requests from the UE application and interacts with OSs and mobile edge orchestrators for further processing of these requests.
The user APP life cycle management agent can only be accessed within the mobile network and can only be used with the support of mobile edge systems.
4〉User APP and user-oriented services
In Figure 8, it also includes two items: user APP and user-oriented services. User APP refers to those APPs that can interact with the mobile edge system through the user APP survival management agent.
User-oriented services can allow the operator’s third-party customers (such as some business groups) to select and subscribe to a set of mobile edge applications that meet specific needs, while receiving service-level support from the supplied applications. information.
