Section: 8.107 Node Identifier
Content: Node Identifier shall be coded as depicted in Figure 8.107-1. Figure 8.107-1: Node Identifier The Node Identifier shall contain the Diameter Identity of the node. If the Node Identifier contains a SGSN Identifier then: - the Node Name shall be coded as the Diameter identity of the SGSN as defined in clause 6.4.13 of 3GPP TS 29.173[ Location Services (LCS); Diameter-based SLh interface for Control Plane LCS ]  [57] and; - the Node Realm shall be coded as the Diameter realm identity of the SGSN and as defined in clause 6.4.14 of 3GPP TS 29.173[ Location Services (LCS); Diameter-based SLh interface for Control Plane LCS ]  [57] and; - Both the Node Name and the Node Realm shall be present and neither the Length of Node Name nor the Length of Node Realm shall be zero. If the Node Identifier contains a MME Identifier then: - the Node Name shall be coded as the Diameter identity of the MME as defined in clause 6.4.4 of 3GPP TS 29.173[ Location Services (LCS); Diameter-based SLh interface for Control Plane LCS ]  [57] and; - the Node Realm shall be coded as the Diameter realm identity of the MME as defined in clause 6.4.12 of 3GPP TS 29.173[ Location Services (LCS); Diameter-based SLh interface for Control Plane LCS ]  [57] and; - Both the Node Name and the Node Realm shall be present and neither the Length of Node Name nor the Length of Node Realm shall be zero. If the Node Identifer contains a 3GPP AAA Server Identifier then: - the Node Name shall be coded as the 3GPP-AAA-Server-Name as defined in clause 8.2.3.24 of 3GPP TS 29.273[ Evolved Packet System (EPS); 3GPP EPS AAA interfaces ]  [68] and; - the Node Realm shall be coded as the Diameter realm of the 3GPP AAA server in the format of a Diameter identity as defined in IETF RFC 3588 [39]. If the Node Identifier contains an SCEF/IWK-SCEF information, then: - the Node Name shall be coded as the SCEF-ID as defined in clause 8.4.5 of 3GPP TS 29.336[ Home Subscriber Server (HSS) diameter interfaces for interworking with packet data networks and applications ]  [69] and; - the Node Realm shall be coded as the Diameter realm of the SCEF as defined in clause 7.3.207 of 3GPP TS 29.272[ Evolved Packet System (EPS); Mobility Management Entity (MME) and Serving GPRS Support Node (SGSN) related interfaces based on Diameter protocol ]  [70].
