Besides the definitions according to the CTS stage 1 service description [2] the following definitions are applicable to the present document:

Fixed network: A PSTN or ISDN network.

Access network: the network on which the CTS-FP is connected and which carries the incoming and outgoing calls to the CTS-FP. It could be either a fixed network or a GSM network.

CTS radio interface: The radio interface between CTS-MS and CTS-FP.

CTS-MSIx: CTS Local Mobile Subscriber Identity related to the xth CTS-MS initialised on a CTS-FP

CTS-MS attachment: CTS-MS attachment is a procedure which a CTS-MS initiates when the CTS-MS detects that it is within coverage of a CTS-FP to which the CTS-MS is enrolled.

CTS-MS detachment: CTS-MS detachment is a procedure that the CTS-MS initiates, and indicates to the CTS-FP that the CTS-MS will be no longer reachable by the CTS-FP.

Enrollment: The procedure by which a CTS-MS is made known to a CTS-FP in order that the CTS-FP can provide CTS service.
