name: COUNT-C
full_form: Time variant parameter for synchronisation of ciphering
context: The ciphering sequence number COUNT-C is 32 bits long. There is one COUNT-C value per up-link radio bearer and one COUNT-C value per down-link radio bearer using RLC AM or RLC UM. For all transparent mode RLC radio bearers of the same CN domain COUNT-C is the same, and COUNT-C is also the same for uplink and downlink. COUNT-C is composed of two parts: a "short" sequence number and a "long" sequence number. The "short" sequence number forms the least significant bits of COUNT-C while the "long" sequence number forms the most significant bits of COUNT-C. The update of COUNT-C depends on the transmission mode as described below (see figure 16c). Figure 16c: The structure of COUNT-C for all transmission modes - For RLC TM on DCH, the "short" sequence number is the 8-bit connection frame number CFN of COUNT-C. It is independently maintained in the ME MAC-d entity and the SRNC MAC-d entity. The "long" sequence number is the 24-bit MAC-d HFN, which is incremented at each CFN cycle. - For RLC
description: COUNT-C is a time variant parameter used for synchronisation of ciphering in the 3GPP network. It is a 32-bit value that consists of two parts: a 'short' sequence number and a 'long' sequence number, which are updated based on the transmission mode.
explanation: The text describes COUNT-C as a parameter used for synchronisation within the 3GPP network, highlighting its role in controlling network operations. This classification aligns with the definition of a parameter.
