25、 a specified portion of the information-carrying capacity of an interface. Channels are classified by channel types, which have common characteristics. Channel types appearing on the radio interface are specified in clauses 3 and 4. At a given time, the complete interface between a Base Station and

26、the set of Mobile Stations in relation corresponds to some interface structure. The interface structure may change in time. The number of possible different such interface structures can be large. The BS access capability is a description of all the possible interface structures of the considered BS

27、. BS access capabilities are specified in sub-clause 8. At a given moment, the channel configuration of a Mobile Station is the interface structure this Mobile Station actually uses to transmit information to or receive information from the Base Station. The channel configuration may change in time.

28、 A limited number of channel configurations are identified, and are specified in sub-clause 9. A Mobile Station access capability is the description of the set of its possible channel configurations. MS access capabilities are specified in sub-clause 8.

29、 44.003 version 14.0.0 Release 145 Channel types and their use: Traffic channels and user channels 5.1 User channels User channels are intended to carry a wide variety of user information streams. A distinguishing characteristic is that user channels do not carry signalling information for Connectio

30、n Management (CM), Mobility Management (MM) or Radio Resource (RR) management. This signalling information is carried over other types of channels, namely the control channels. User channels may be used to provide access to the PLMN and the networks it permits access to. Different types of user chan

31、nels are distinguished by their rates. 5.2 Bm Channel A Bm channel is a bi-directional or uni-directional user channel able to carry: - a 13 kbit/s rate bit stream with an error structure and a transmission delay compatible with some grade of service, intended to carry voice encoded according to Tec

32、hnical Specifications in 3GPP TS 06-series; or - a bit stream at a rate of 14,5 kbit/s, 12 kbit/s, 6 kbit/s or 3,6 kbit/s, with an error structure and a transmission delay adapted to a wider range of services, including data transmission; or other kinds of bit stream adapted to a wider range of serv

33、ices (for further study). User information streams are carried on the Bm channel on a dedicated, alternate (within one call or as separate calls), or simultaneous basis, consistent with the Bm channel carrying capability. The following are samples of user information streams: i) voice encoded at 13

34、kbit/s according to Technical Specifications in 3GPP TS 06-series; and ii) data information corresponding to circuit switching user classes of services at bit rates compatible with the channel capability. A Bi-directional Bm Channel uses the radio resources referred to as TCH/F. Bi-directional downl

35、ink Bm Channel uses the radio resources referred to as TCH/FD. The Uni-directional Bm Channel is only defined in downlink direction. Traffic channels (TCH) are fixed physical gross rate channels, accompanied with timing (see 3GPP TS 45.002). 5.3 Lm Channels A Lm channel is a user channel with a carr

36、ying capability lower than a Bm channel. A Lm channel is a user channel able to carry: - some bit stream to be defined with an error structure and a transmission delay compatible with some grade of service, intended to carry voice encoded according to a method to be defined; - a bit stream at a rate

37、 of 6 kbit/s or 3,6 kbit/s, with an error structure and a transmission delay adapted to a wider range of services, including data transmission; or - other kinds of bit stream adapted to a wider range of services (for further study). ETSI ETSI TS 144 003 V14.0.0 (2017-04)73GPP TS 44.003 version 14.0.

38、0 Release 14User information streams are carried on a Lm channel on a dedicated, alternate (within one call or as separate calls), or simultaneous basis, consistent with the TCH/H channel carrying capability. The following are samples of user information streams: i) voice encoded at some rate accord

39、ing to a method to be specified in the future; and ii) data information corresponding to circuit switching user classes of services at bit rates compatible with the channel capability. A Lm Channel uses the radio resources referred to as TCH/H. Traffic channels (TCH) are fixed physical gross rate ch

40、annels, accompanied with timing (see 3GPP TS 45.002). 6 Channel types and their use: Packet data traffic channels Packet data traffic channels are used to carry a wide variety of information streams, including user information and signalling information for, e.g. Session Management (SM) and Mobility

41、 Management (MM) in packet mode. A distinguishing characteristic is that a packet data traffic channel allows a plurality of information streams, associated with different users, to be multiplexed in a pre-emptive and dynamic fashion. Signalling functions between the MS and the BSS are carried out o

42、ver other types of channels, namely the control channels. Uni-directional information streams are carried on the packet data traffic channel on an alternate, or simultaneous basis, consistent with the packet data traffic channel carrying capability. The packet data traffic channel uses the radio res

43、ources referred to as PDTCH or Extended Coverage PDTCH (EC-PDTCH) (see 3GPP TS 45.002). 7 Channel types and their use: Control channels NOTE: The term “Dm channel“ may be used to refer to the controls channels used by a Mobile Station at a given moment, independently of their type. (The term “Dm cha

44、nnel“ in conjunction with the packet control channels shall be avoided.) Control channels are used to provide all active Mobile Stations with a continuous frame oriented means of communication across the MS-BS interface. A Mobile Station Channel Configuration contains one or more control channels. T

45、hese control channels may change in time, with the channel configuration. Access management signalling functions are used to insure the continuity when a change in the control channels occurs. Control channels are classified by control channel types, which have common characteristics. These control

46、channel types are specified in sub-clause 7.1. The control channels are primarily intended to carry signalling information for Connection Management (CM), Mobility Management (MM) and Radio Resource (RR) management. In addition to signalling information control channels may also be used to carry oth

47、er data, including those relating to Short Message Services (SMS). 7.1 Control channel types 7.1.1 Broadcast Control Channel A broadcast control channel is a point-to-multipoint uni-directional control channel, from the fixed sub-system to the Mobile Stations. Broadcast control channels are physical

48、ly sub-divided into the Broadcast Control CHannel (BCCH) , Packet Broadcast Control CHannel (PBCCH), Compact Packet Broadcast cControl CHannel (CPBCCH), and Extended Coverage Broadcast Control CHannel (EC-BCCH). BCCH, PBCCH, CPBCCH and EC-BCCH are intended to broadcast a variety of information to MS

49、s, including information necessary for MS to register in the system (e.g. synchronization data). ETSI ETSI TS 144 003 V14.0.0 (2017-04)83GPP TS 44.003 version 14.0.0 Release 14BCCH, PBCCH, CPBCCH and EC-BCCH use a protocol specified in Technical Specifications in 3GPP TS 44-Series. 7.1.2 Common Control Channel A common control channel is a point-to-multipoint bi-directional control channel. Common control channels are physically sub-divided into the Common Control CHannel (CCCH), the Packet Common Control CHannel (PCCCH), the Compact Packet Common Control CHannel
