name: T3260
full_form: Timer 3260
context: The network initiates the authentication procedure by transferring an AUTHENTICATION REQUEST message across the radio interface and starts the timer T3260. The AUTHENTICATION REQUEST message contains the parameters necessary to calculate the response parameters (see 3GPP TS 43.020 [13] (in case of GSM authentication challenge) and 3GPP TS 33.102 [5a] (in case of an UMTS authentication challenge)). In a GSM authentication challenge, the AUTHENTICATION REQUEST message also contains the GSM ciphering key sequence number allocated to the key which may be computed from the given parameters. In a UMTS authentication challenge, the AUTHENTICATION REQUEST message also contains the ciphering key sequence number allocated to the key set of UMTS ciphering key, UMTS integrity key and GSM ciphering key which may be computed from the given parameters. Furthermore, the ciphering key sequence number is also linked to a GSM Kc128 if after the authentication procedure the network in A/Gb mode selects an A5 ciphering algorithm that requires a 128-bit ciphering key.
description: The T3260 timer is started by the network when sending an AUTHENTICATION REQUEST message across the radio interface. This timer is used to manage the authentication procedure's timing.
explanation: Classified as a Timer since it is a mechanism for managing timing in telecommunications processes.
