33、dependent. These attributes are described anddefined in GSM 02.01 2. They are grouped into four categories:i) Information transfer attributes, which characterize the network capabilities for transferring information from auser access point in a GSM PLMN to a user access point in another network. (Re
34、fer to GSM 02.01 2 andGSM 04.02 5 for definitions of user access points, originating and terminating networks).ii) Access attributes, which describe the means for accessing network functions or facilities as seen at the accesspoint in the PLMN (see GSM 02.01 2).iii) Interworking attributes, which de
35、scribe properties of the terminating network and its access point. Theterminating network may include another GSM PLMN or the originating PLMN (see GSM 02.01 2).iv) General attributes, which deal with the service in general.Figure 1 shows the relation between the groups of attributes and their field

43、ications 10 to 15 and 21.2 Bearer Service categoriesAll Bearer Service categories provide information transfer between R/S reference points and allow the use of sub-rateinformation streams which are rate-adapted.The Bearer Services can be grouped into the following categories:- Unrestricted Digital
44、Information (UDI);Provides the transfer of unrestricted digital information.- 3,1 kHz (External to the PLMN);Used to select a “3,1 kHz audio“ interworking function at the MSC. This service category is used wheninterworking with the ISDN or PSTN “3,1 kHz audio“ service and includes the capability to
45、select a modem atthe interworking function. “External to the PLMN“ indicates that the “3,1 kHz audio“ service is only used outsideof the PLMN, in the ISDN/PSTN. The connection within the PLMN, user access point to the interworkingfunction, is an unrestricted digital connection.-PAD;Provides an async
46、hronous connection to a PAD. This enables PLMN subscribers to access a packet network(PSPDN/ISDN). See GSM 09.05 13 for service and interworking specifications.- Packet;Provides a synchronous connection that enables PLMN subscribers to access a packet network (PSPDN/ISDN).See GSM 09.06 14 for servic
47、e and interworking specifications.- Alternate Speech/Data;Provides the capability to swap between speech and data during a call.If either the speech or data portion of the call requires a full rate channel, a full rate channel shall be used for theduration of the call.- If the data portion of the ca
48、ll requires multiple full rate channels, the speech portion uses a single full ratechannel.The access interface at the mobile station for the data portion is assumed to be a standard data interface. Somemeans must be provided to select the speech/data capability.- Speech followed by Data;Provides a
49、speech connection first and then at some time while the call is in progress, the user can switch to adata connection. The user cannot switch back to speech after the data portion.If either the speech or data portion of the call requires a full rate channel, a full rate channel shall be used fromthe start of the call. The network may then change to a half rate channel for the data portion.- If the data portion of the call requires multiple full rate channels, a single full rate channel shall be u
