The present document specifies that set of technical requirements for Digital Enhanced Cordless Telecommunications (DECT) Fixed Part (FP) and DECT Portable Part (PP) necessary for the support of the Cordless Terminal Mobility (CTM) Feature Package 1 (CTM-FP1).
The objective of the present document is to ensure the Air Interface (AI) interoperability of DECT CTM-FP1 PPs and DECT CTM-FP1 FPs if applied. The CTM service allows users of cordless terminals to be mobile within and between networks. Where radio coverage is
provided and the cordless terminal has appropriate access rights the user will be able to make calls from, and to receive calls at, any location within the fixed public and/or private networks, and may move without interruption of a call in progress.
CTM-FP1 defines 32 Kbit/s Circuit Switched Data services (CSD) for CTM users. The present document is intended as an extension of the DECT CTM Access Profile (ETS 300 824 [10]) mobility features mandatory base covering the requirements for CTM-FP1.
