In general, the ME can operate either as SAP server or as SAP client. A brief description of the configuration is<br />

given below.<br />

• SAP server<br />

The SIM Access Server has direct (galvanic) access to a SIM. It acts as a SIM card reader, which assists the<br />

client in accessing and controlling this SIM via the serial link. Typical examples of a server are SIM card<br />

reader or mobile phones.<br />

After SAP client activation (see (1) in Figure 15.3, SIM usage states of SAP server) the ME starts sending the<br />

SAP message CONNECTION_REQ. However, the client will still use its local SIM card until a server<br />

responds and the parameter negotiation with subsequent <strong>AT</strong>R access has been accomplished successfully.<br />
