The 5G Edge computing service is described in TS 23.548
. It defines the enhancements of 5G System to support Edge Computing.
It is defined in clause 6.4 of TS 23.548
that the network could expose network information to the local AF with two scenarios, i.e.
Case 1: L-PSA UPF may expose the network information to local AF via Local NEF, or
Case 2: L-PSA UPF may expose the network information to local AF directly. However, How to deliver the information on N6 is out of scope.
For the Case 1, the Security aspects of Network Exposure Function specified in clause 12
shall be used for the network information exposure.
of the present document should be followed, with the following additions, to protect the discovery messages between the UE and the EASDF which is used as the DNS server for EAS discovery in the non-roaming case. If the core network is used to configure the security information, the SMF is preconfigured with the EASDF security information (credentials to authenticate the EASDF, supported security mechanisms, port number, etc.) and provides the security information to the UE as follows:
The SMF provides the EASDF security information to the UE via PCO.
