8.1 General

This clause describes deployments of the functional model specified in clause 6.

8.2 Deployment of SEAL server(s)

The SEAL server(s) may be deployed either in the PLMN operator domain or deployed in the VAL service provider domain. The SEAL server(s) connects with the 3GPP network system in one or more PLMN operator domain. The SEAL server(s) may be supporting multiple VAL servers.

8.2.1 SEAL server(s) deployment in PLMN operator domain

Figure 8.2.1-1 illustrates deployment of the SEAL server(s) in a single PLMN operator domain and the VAL server(s) in the VAL service provider domain.

Figure 8.2.1-1: SEAL server(s) deployed in a single PLMN operator domain

Figure 8.2.1-2 illustrates the deployment of SEAL server(s) in multiple PLMN operator domain and provides SEAL services to the VAL server(s) deployed in the VAL service provider domain. SEAL servers deployed in multiple PLMN operator domain are not interconnected.

Figure 8.2.1-3 illustrates the deployment of SEAL servers in multiple PLMN operator domain and provides SEAL services to the VAL server(s) deployed in the VAL service provider domain. SEAL servers deployed in multiple PLMN operator domain are interconnected.

Figure 8.2.1-4 illustrates the deployment of SEAL servers in a single PLMN operator domain and provides SEAL services to the VAL server(s) deployed in the VAL service provider domain. SEAL servers deployed in a single PLMN operator domain are interconnected.

8.2.2 SEAL server(s) deployment in VAL service provider domain

Figure 8.2.2-1 illustrates deployment of the SEAL server(s) and the VAL server(s) in VAL service provider domain.

Figure 8.2.2-1: Deployment of SEAL server(s) with connections to 3GPP network system in a single PLMN operator domain

Figure 8.2.2‑2 illustrates deployment of the SEAL server(s) which connects to the 3GPP network system in multiple PLMN operator domain.

Figure 8.2.2‑2: Deployment of SEAL server(s) with connections to 3GPP network system in multiple PLMN operator domains

Figure 8.2.2‑3 illustrates the deployment of multiple SEAL servers in the VAL service provider domain where SEAL server 1 and SEAL server 2 connect with 3GPP network system of PLMN operator domain 1 and PLMN operator domain 2 respectively. The SEAL servers interconnect via SEAL-E and support the VAL service provider domain applications for the VAL UEs connected via both the PLMN operator domains.

8.2.3 SEAL server(s) deployment outside of VAL service provider domain and PLMN operator domain

Figure 8.2.3-1 illustrates deployment of the SEAL server(s) outside of both the VAL service provider domain and PLMN operator domain i.e. in SEAL provider domain.
