Foreword This Technical Specification (TS) has been produced by ETSI Project Digital Enhanced Cordless Telecommunications (DECT). The present document is based on DECT Common Interface (CI) specification E
20、N 300 175, parts 1 1 to 8 8 to enable DECT terminals to interwork in the public and private environment when connected to an IP network. In addition, for the purpose of interoperability and wherever it is found appropriate, the present document takes into consideration the requirements of: the DECT
21、Generic Access Profile (GAP), EN 300 444 13 to enable the same DECT portable part (PT) to interwork with a DECT fixed part (FP) complying to the GAP requirements, irrespective of whether this FP provides residential, business or public access services; the DECT Packet Radio Service (DPRS), EN 301 64
22、9 16 to enable DECT data terminals to interwork with a DECT FP complying to the DPRS requirements, irrespective of whether this FP provides residential, business or public access services. General attachment requirements are based on EN 301 406 15. Further details on the DECT system may be found in
23、TR 101 178 11, EN 300 176-1 9 and EN 300 176-2 10. ETSI ETSI TS 102 265 V1.2.1 (2004-10) 6 1 Scope The present document specifies additional requirements for DECT Internet Protocol (IP) applications including networking aspects, Voice over IP (VoIP) and other multimedia exchange over IP, mobility an
24、d quality of service properties. It provides an end system, i.e. termination of IP into the DECT Fixed Termination (FT). NOTE: Transparent IP packet service is described in EN 301 649 16, DPRS standard. 2 References The following documents contain provisions which, through reference in this text, co

38、1 Definitions For the purposes of the present document, the terms and definitions given in EN 300 175-1 1, RFC 3344 17, RFC 3261 18 and the following apply: DECT User Agent (UA): logical entity comprising the SIP functionality provided by the DECT Fixed Termination User Agent (FT-UA) and DECT Portab
39、le Termination User Agent (PT-UA) NOTE: Physically it includes one DECT FP and one or more DECT PPs. ETSI ETSI TS 102 265 V1.2.1 (2004-10) 8 netmask: string of 0s and 1s that mask out the network part of an IP address(IP) so that only the host computer part of the address remains NOTE: A 32-bit bit
40、mask shows how an Internet address is to be divided into network, subnet and host parts. A frequently-used netmask is 255.255.255.0. (255 is the decimal equivalent of a binary string of eight ones.) Used for a Class C subnet (one with up to 255 host computers), the “.0“ in the “255.255.255.0“ netmas
41、k allows the specific host computer address to be visible. session ID: field in a SIP message as defined in RFC 3261 18 3.2 Symbols For the purposes of the present document, the following symbols apply: M mandatory to support (provision mandatory, process mandatory) O optional to support (provision
42、optional, process mandatory) I out-of-scope (provision optional, process optional) not subject for testing C conditional to support (process mandatory) N/A not applicable (in the given context the specification makes it impossible to use this capability) Provision mandatory, process mandatory means
43、that the indicated feature service or procedure shall be implemented as described in the present document, and may be subject to testing. Provision optional, process mandatory means that the indicated feature, service or procedure may be implemented, and if implemented, the feature, service or proce
