A.3.1 General

This clause shows some examples for how the ECS can be deployed in relation to the UE

A.3.2 UE (EEC) served by a single ECS

In this scenario the UE can contain a single AC or multiple ACs, however the UE contains a single EEC which is configured with the address of a single ECS. This could for example be an IoT device that only supports a single AC or a smartphone device which contains many ACs which are served by a single ECS.

A.3.3 UE (EECs) served by multiple ECSs

In this scenario the user is allowed to install multiple ACs in the UE where each AC can be served by an EAS which in turn served by a different ECSP’s EES/ECS.

One example is that multiple ACs are installed on a smartphone and the associated EASs are on-boarded onto different ECSP’s EESs which are registered with different ECSs.

Another example is a UE that supports Dual SIM. In this scenario the UE can support concurrent connection to two PLMNs.
