2.1.1  Random valuesWord‑p. 42
In a number of places in the present document, it is mentioned that some value must take a "random" value, in a given range, or more generally with some statistical distribution. Such cases interest only the Mobile Station.
It is required that there is a low probability that two MSs in the same conditions (including the case of two MSs of the same type from the same manufacturer) will choose the same value. Moreover, it is required that, if it happens that two MSs in similar conditions choose the same value, the probability of their choices being identical at the next occasion is the same as if their first choices had been different.
The meaning of such a specification is that any statistical test for these values, done on a series of similar events, will obtain a result statistically compatible with the specified distribution. This shall hold even in the cases where the tests are conducted with a subset of possible events, with some common parameters. Moreover, basic tests of independence of the values within the series shall pass.
Data against which correlation with the values shall not be found are the protocol state, or the IMSI, or identities or other unrelated information broadcast by the network, or the current TDMA frame number.

2.1.2  Vocabulary |R8|

For the purposes of the present document, the following terms and definitions apply:
  • A GSM security context is established and stored in the MS and the network as a result of a successful execution of a GSM authentication challenge. The GSM security context for the CS domain consists of the GSM ciphering key and the ciphering key sequence number. The GSM security context for the PS domain consists of the GPRS GSM ciphering key and the GPRS ciphering key sequence number.
  • A UMTS security context is established and stored in the MS and the network as a result of a successful execution of a UMTS authentication challenge. The UMTS security context for the CS domain consists of the UMTS ciphering key, the UMTS integrity key, the GSM ciphering key, the ciphering key sequence number and the GSM Kc128 (if an A5 ciphering algorithm that requires a 128-bit ciphering key is in use). The UMTS security context for the PS domain consists of the GPRS UMTS ciphering key, the GPRS UMTS integrity key, the GPRS GSM ciphering key, the GPRS ciphering key sequence number, the GPRS GSM Kc128 (if a GEA ciphering algorithm that requires a 128-bit ciphering key is in use) and the GPRS GSM Kint (if a GIA integrity algorithm that requires a 128-bit integrity key is in use).
  • An MS is attached for emergency bearer services if it has successfully completed an attach for emergency bearer services or if it has only a PDN connection for emergency bearer services established.
  • idle mode: In this mode, the mobile station is not allocated any dedicated channel; it listens to the CCCH and the BCCH;
  • group receive mode: (Only applicable for mobile stations supporting VGCS listening or VBS listening) In this mode, the mobile station is not allocated a dedicated channel with the network; it listens to the downlink of a voice broadcast channel or voice group call channel allocated to the cell. Occasionally, the mobile station has to listen to the BCCH of the serving cell as defined in TS 43.022 and TS 45.008;
  • dedicated mode: In this mode, the mobile station is allocated at least two dedicated channels, only one of them being a SACCH;
  • EAB: Extended Access Barring, see TS 22.011.
  • group transmit mode: (Only applicable for mobile stations supporting VGCS talking) In this mode, one mobile station of a voice group call is allocated two dedicated channels, one of them being a SACCH. These channels can be allocated to one mobile station at a time but to different mobile stations during the voice group call;
  • packet idle mode: (only applicable for mobile stations supporting GPRS) In this mode, mobile station is not allocated any radio resource on a packet data physical channel; it listens to the BCCH and the CCCH, see TS 44.060.
  • packet transfer mode: (only applicable for mobile stations supporting GPRS) In this mode, the mobile station is allocated radio resource on one or more packet data physical channels for the transfer of LLC PDUs.
  • main DCCH: In dedicated mode and group transmit mode, only two channels are used as DCCH, one being a SACCH, the other being a SDCCH or a FACCH; the SDCCH or FACCH is called here "the main DCCH";
  • A channel is activated if it can be used for transmission, in particular for signalling, at least with UI frames. On the SACCH, whenever activated, it must be ensured that a contiguous stream of layer 2 frames is sent;
  • A TCH is connected if circuit mode user data can be transferred. A TCH cannot be connected if it is not activated. A TCH which is activated but not connected is used only for signalling, i.e. as a DCCH;
  • The data link of SAPI 0 on the main DCCH is called the main signalling link. Any message specified to be sent on the main signalling link is sent in acknowledged mode except when otherwise specified;
  • The term "to establish" a link is a short form for "to establish the multiframe mode" on that data link. It is possible to send UI frames on a data link even if it is not established as soon as the corresponding channel is activated. Except when otherwise indicated, a data link layer establishment is done without an information field.
  • "channel set" is used to identify TCHs that carry related user information flows, e.g., in a multislot configuration used to support circuit switched connection(s), which therefore need to be handled together.
  • A temporary block flow (TBF) is a physical connection used by the two RR peer entities to support the uni-directional transfer of LLC PDUs on packet data physical channels, see TS 44.060.

  • In UTRAN Iu mode,... Indicates this paragraph applies only to a system which operates in UTRAN Iu mode. For multi system case this is determined by the current serving radio access network.
  • In a shared network,... Indicates this paragraph applies only to a shared network. For the definition of shared network see TS 23.122.

  • The term "eCall only" applies to a mobile station which is in the eCall only mode, as described in TS 22.101.
  • "removal of eCall only restriction" means that all the limitations as described in TS 22.101 for the eCall only mode do not apply any more.
  • "SMS-only service": A subset of services which includes only short message service. The MS can request "SMS-only service" in order to obtain SMS.
  • Access domain selection: The process to select whether the CS domain or the IMS/IP CAN is used to transmit the call control signalling between MS and core network. Definition derived from TS 23.221.
