name: U4 UPDATING DISABLED
full_form: Location updating has been disabled
context: In parallel with the sublayer states described in subclause 4.1.2.1 and which control the MM sublayer protocol, an update status exists. The update status pertains to a specific subscriber embodied by a SIM/USIM. This status is defined even when the subscriber is not activated (SIM/USIM removed or connected to a switched-off ME). It is stored in a non volatile memory in the SIM/USIM. The update status is changed only as a result of a location updating procedure attempt (with the exception of an authentication failure and of some cases of CM service rejection). In some cases, the update status is changed as a result of a GPRS attach, GPRS routing area update, service request network initiated GPRS detach procedure or due to change in LAI while timer T3246 running. U1 UPDATED The last location updating attempt was successful (correct procedure outcome, and the answer was acceptance from the network). With this status, the SIM/USIM contains also the LAI of the LA where the subscriber is registered, and possibly valid TMSI, GSM ciphering key, UMTS integrity key, UMTS ciphering key and ciphering key sequence number. Furthermore, if the ME supports any A5 ciphering algorithm that requires a 128-bit ciphering key and a USIM is in use, then the ME may contain a valid GSM Kc128. The "Location update status" stored on the SIM/USIM shall be "updated". U2 NOT UPDATED The last location updating attempt made failed procedurally (no significant answer was received from the network, including the cases of failures or congestion inside the network). For this status, the SIM/USIM can contain a valid LAI of the location area to which the subscriber was registered, and possibly also a valid TMSI, GSM ciphering key, UMTS integrity key, UMTS ciphering key and ciphering key sequence number. For compatibility reasons, all these fields shall be set to the "deleted" value if the LAI is deleted. However the presence of other values shall not be considered an error by the mobile station. Furthermore, if the ME supports any A5 ciphering algorithm that requires a 128-bit ciphering key and a USIM is in use, then the ME shall delete the GSM Kc128 stored if the LAI is deleted. The "Location update status" stored on the SIM/USIM shall be "not updated". U3 ROAMING NOT ALLOWED The last location updating attempt run correctly, but the answer from the network was negative (because of roaming or subscription restrictions). For this status, the SIM/USIM can contain a valid LAI, TMSI, GSM ciphering key, UMTS integrity key, UMTS ciphering key or ciphering key sequence number. For compatibility reasons, all these fields shall be set to the "deleted" value if the LAI is deleted. However the presence of other values shall not be considered an error by the mobile station. Furthermore, if the ME supports any A5 ciphering algorithm that requires a 128-bit ciphering key and a USIM is in use, then the ME shall delete the GSM Kc128 stored if the LAI is deleted. The "Location update status" stored on the SIM/USIM shall be "Location Area not allowed". U4 UPDATING DISABLED Location updating has been disabled. For this status, the SIM/USIM does not contain any valid LAI, TMSI, GSM ciphering key, UMTS integrity key, UMTS ciphering key or ciphering key sequence number. For compatibility reasons, all these fields shall be set to the "deleted" value at the moment the status is set to eCALL INACTIVE. However the presence of other values shall not be considered an error by the mobile station. Furthermore, if the ME supports any A5 ciphering algorithm that requires a 128-bit ciphering key and a USIM is in use, then the ME shall delete the GSM Kc128 stored at the moment the status is set to eCALL INACTIVE. The "Location update status" stored on the SIM/USIM shall be "not updated".
description: The SIM/USIM does not contain any valid LAI, TMSI, GSM ciphering key, UMTS integrity key, UMTS ciphering key or ciphering key sequence number.
explanation: Classified as a Status because it describes a specific state or condition of the location update process.
