19、 662-1 3 DEFINITIONS AND ABBREVIATIONS 3.1 Definitions For the purposes of this Standard, the following definitions apply. Access Profile: A set of agreed features, processes and attributes that define a designated level of compatibility, interoperability, and/or interworking. NOTE: The terms Public
20、 Access Profile (PAP) and Generic Access Profile (GAP) are restricted to DECT use. The terms Customer Premises Access Profile (CPAP) and Data Services Access Profile (DSAP) are used by PWT devices. Antenna diversity: the Radio Fixed Part (RFP) for each bearer can select independently different anten
21、na properties such as gain, polarization, coverage patterns, and other features that may modify the practical coverage. A typical example is space diversity, provided by two vertically polarized antennas separated by 10 - 20 cm. Attach: the process whereby a portable part within the coverage area of
22、 a fixed part to which it has access rights, notifies this fixed part that it is operative. The reverse process is detach, which reports the portable part as inoperative. NOTE: An operative portable part is assumed to be ready to receive calls. Authentication (of a subscriber): the process whereby a
23、 PWT subscriber is positively verified to be a legitimate user of a particular fixed part. NOTE: Authentication is generally performed at call Set-up, but may also be done at any other time (e.g. during a call). Bearer: see Medium Access Control (MAC) bearer or bearer service. Bearer handover: the i
24、nternal handover process provided by the MAC layer, whereby one MAC connection can modify its underlying bearers while maintaining the service provided to the Data Link Control (DLC) layer. NOTE: Bearer handover is slot based. Bearer service: a type of telecommunication service that provides a defin
25、ed capability for the transmission of signals between user-network interfaces. NOTE: The PWT user-network interface corresponds to the top of the PWT network layer (layer 3). Broadcast: a simplex point-to-multipoint mode of transmission. NOTE: The transmitter may disregard the presence or absence of
26、 receivers. C-plane: the control plane of the PWT protocol stacks, which contains all of the internal PWT protocol control, but may also include some external user information. NOTE: The C-plane stack always contains protocol entities up to and including the network layer. Call: all of the NetWorK (
27、NWK) layer processes involved in one network layer peer-to-peer association. NOTE: Call may sometimes be used to refer to processes of all layers, since lower layer processes are implicitly required. 4 STD-EIA TIA-662-ENGL 1998 m 3234600 0596079 187 m TINEIA 662-1 Cell: the domain served by a single
28、 antenna system (including a leaky feeder) of one fixed part. NOTE: A cell may include more than one source of radiated Radio Frequency (RF) energy (.e. more than one radio end point). Central Control Fixed Part (CCFP): a physical grouping that contains the central elements of a fixed part. A fixed
29、part shall contain a maximum of one CCFP. NOTE: A CCFP controls one or more RFPs. Centrex: an implementation of a private telecommunication network exchange that is not located on the premises of the private network operator. It may be co-located with, or physically a part of a public exchange. Chan
30、nel: see physical channel. Cluster: a logical grouping of one or more cells between which bearer handover is possible. A Cluster Control Function (CCF) controls one cluster. NOTE: Internal handover to a cell which is not part of the same cluster can only be done by connection handover. Connection: s
31、ee “MAC connection.“ Connection handover: the internal handover process provided by the DLC layer, whereby one set of DLC entities (C-plane and U-plane) can reroute data from one MAC connection to a second new MAC connection, while maintaining the service provided to the network layer. NOTE: Connect
32、ion handover is DLC frame based. ConnectionLess mode (CIL): a transmission mode that transfers one packet (one self contained unit) of data from one source point to one (or more) destination points in a single phase. NOTE: Connectionless transmissions require the peer-to-peer associations to be prea
33、rranged, and the transmission is unacknowledged at that layer. Connection Oriented mode (CIO): a transmission mode that transfers data from one source point to one or more destination points using a protocol based on three phases: “Set-up“, “Data transfer“ and “Release.“ NOTE: Connection oriented mo
34、de requires no prearranged associations between peer entities (unlike C/L mode). Cordless Radio Fixed Part (CRFP): a physical grouping that combines elements of both PTs and FTs to relay information on a physical channel from one PWT termination to a physical channel for another PWT termination. The
35、 CRFP is an RFP as regards the functionality towards PPs. It has an RFP identity and is by PPs regarded as part of the FP, indistinguishable from RFPs of this FP. NOTE: The PWT termination can be a PT or an FT or another CRFP. Coverage area: the area over which reliable communication can be establis
36、hed and maintained. 5 TIAIEIA 662-1 Customer Premises Access Profile (CPAP): a defined part of PWT that ensures interoperability between FPs and PPs for environments typified by requirements for high density of users, and high demands for transmission quality and throughput. Note: Data Services Acce
37、ss Profile (DSAP): a defined part of PWT that ensures interoperability between FPs and PPs for environments typified by requirements for datdpacket transmissions with high user density and high demands for transmission quality and throughput. Note: DLC broadcast: a simplex “connectionless“ mode of t
38、ransmission from the DLC broadcast entity of one fixed radio termination to the DLC broadcast entities in one or more portable radio terminations. This tem applies only to PWT Systems This term applies only to PWT Systems NOTE: The transmitter may disregard the presence or absence of receivers. DLC
39、data link (DLC LINK): an association between two DLC layer entities. This can either be one C-plane association or one U-plane association. NOTE: This is not the same as a MAC connection. DLC frame: the format used to structure all messages that are exchanged between DLC layer peer entities. NOTE: D
40、ifferent DLC frames are used in the C-plane and the U-plane. and there is more than one format of DLC frame in each plane. Double-simplex bearer: the use of two simplex bearers operating in the same direction on two physical channels. These pairs of channels shall always use the same RF carrier and
41、shall always use evenly spaced slots (.e. separated by 0.5 Time Division Multiple Access (TDMA) frame). A double-simplex bearer shall only exist as part of a multibearer MAC connection. Down-link: transmission in the direction FT to PT. Duplex bearer: the use of two simplex bearers operating in oppo
42、site directions on two physical channels. These pairs of channels shall always use the same RF carrier and shall always use evenly spaced slots (.e. separated by 0.5 TDMA frame). End System (ES): a logical grouping that contains application processes and supports telecommunication services. NOTE: Fr
43、om the OS1 point of view, end systems are considered as sources and sinks of information. External handover: the process of switching a call in progress from one fixed radio termination to another fixed radio termination. Field: a continuous region of data (.e. adjacent bits) that jointly convey inf
44、ormation. Typically, a message will contain several fields. If data is not continuous then it shall be defined as two (or more) fields. Fixed Part (PWT Fixed Part) (FP): a physical grouping that contains all of the elements in the PWT network between the local network and the PWT air interface. NOTE
45、: A PWT fixed part contains the logical elements of at least one fixed radio termination, plus additional implementation specific elements. Fixed radio Termination (FT): a logical group of functions that contains all of the PWT processes and procedures on the fixed side of the PWT air interface. 6 S
46、TD-EIA TIA-bb2-ENGL 1998 - 3234600 05%6083 835 TINEIA 662-1 NOTE: A fixed radio termination only includes elements that are defined in the PWI Standard. This includes radio transmission elements (layer 1) together with a selection of layer 2 and layer 3 elements. Flow control: the mechanism that is
47、used to regulate the flow of data between two peer entities. Fragment: one of the service data units that is produced by the process of fragmentation. NOTE: This is not the same as a segment. Fragmentation: the process of dividing a protocol data unit into more than one service data unit for deliver
48、y to a lower layer. The reverse process is recombination. NOTE: This is not the same as segmentation. Frame: see TDMA frame or DLC frame. Full slot (Slot): one 24th of a TDMA frame which is used to support one physical channel. Generic: a generalized set or general purpose set, often in the sense of
49、 basic or ordinary. Geographically unique: two fixed parts with the same PARI, or respectively two RFPs with the same RFPI, can not be reached or listened to at the same geographical position. NOTE: PARI stands for Primary Access Rights Identifier, RFPI stands for Radio Fixed Part Identifier. Global Network (GNW): a telecommunication network capable of offering a long distance telecommunication service. NOTE: The term does not include legal or regulatory aspects, nor does it indicate if the network is a public or a private network. Globally unique identit
