name: ULIC
full_form: UMTS LI Correlation
context: ULIC header contains the following attributes: - Correlation Number. - Message Type (a value of 255 is used for HI3-PDUs). - Direction. - Sequence Number. - Length. - Intercepting Control Element (ICE) type. T-PDU contains the intercepted information. Figure C.1: Outline of ULIC header For interception tunneling the ULIC header shall be used as follows: - Version shall be set to 0 to indicate the first version of ULIC header. - DIR indicates the direction of the T-PDU: "1" indicating uplink (from observed mobile user); and "0" indicating downlink (to observed mobile user). - Message Type shall be set to 255 (the unique value that is used for T-PDU within GTP TS 29.060 [17]). - Length shall be the length, in octets, of the signalling message excluding the ULIC header. Bit 8 of octet 3 is the most significant bit and bit 1 of octet 4 is the least significant bit of the length field. - Sequence Number is an increasing sequence number for tunneled T-PDUs. Bit 8 of octet 5 is the most
description: UMTS LI Correlation (ULIC) is a protocol used for interception tunneling in UMTS networks, specifically for correlating and managing intercepted data between different network elements.
explanation: The text describes ULIC as a set of rules governing how data is transmitted and correlated during interception processes within UMTS networks. This aligns with the definition of a protocol as a set of standardized rules for communication.
