ETSI ETSI TS 132 421 V15.0.0 (2018-06)63GPP TS 32.421 version 15.0.0 Release 15Introduction The present document is part of a TS-family covering the 3rd Gener
32、ation Partnership Project; Technical Specification Group Services and System Aspects; Telecommunication management, as identified below: TS 32.421: “Subscriber and equipment trace: Trace concepts and requirements“; TS 32.422: “Subscriber and equipment trace: Trace control and configuration managemen
33、t“; TS 32.423: “Subscriber and equipment trace: Trace data definition and management“; Subscriber and equipment trace provide very detailed information at call level on one or more specific mobile(s). This data is an additional source of information to Performance Measurements and allows going furth
34、er in monitoring and optimisation operations. Contrary to Performance measurements, which are a permanent source of information, trace is activated on user demand for a limited period of time for specific analysis purposes. Trace plays a major role in activities such as determination of the root cau
35、se of a malfunctioning mobile, advanced troubleshooting, optimisation of resource usage and quality, RF coverage control and capacity improvement, dropped call analysis, Core Network and Access Network end-to-end procedure validation. The capability to log data on any interface at call level for a s
36、pecific user (e.g. IMSI) or mobile type (e.g. IMEI or IMEISV), or service initiated by a user allows getting information which cannot be deduced from Performance measurements such as perception of end-user QoS during his call (e.g. requested QoS vs. provided QoS), correlation between protocol messag
37、es and RF measurements, or interoperability with specific mobile vendors. Moreover, performance measurements provide values aggregated on an observation period; Subscriber and UE Trace give instantaneous values for a specific event (e.g. call, location update, etc.). If performance measurements are
38、mandatory for daily operations, future network planning and primary trouble shooting; Subscriber and UE Trace is the easy way to go deeper into investigation and network optimisation. In order to produce this data, Subscriber and UE Trace are carried out in the NEs, which comprise the network. The d
39、ata can then be transferred to an external system (e.g. an Operations System (OS) in TMN terminology, for further evaluation). ETSI ETSI TS 132 421 V15.0.0 (2018-06)73GPP TS 32.421 version 15.0.0 Release 151 Scope The present document describes the requirements for the management of Trace and the re
40、porting of Trace data (including FDD mode and TDD mode) across UMTS, EPS or 5G networks as it refers to subscriber tracing (tracing of IMSI or Public User Identity) and equipment tracing (tracing of IMEI or IMEISV). Trace also includes the ability to trace all active calls in a cell or multiple cell
41、s (Cell Traffic Trace). The present document also includes the description of Service Level Tracing (tracing of a specific service). It defines the administration of Trace Session activation/deactivation by the management system, the network or User Equipment (UE) itself via signalling, the generati
42、on of Trace results in the Network Elements (NEs) and UE and the transfer of these results to one or more Operations Systems. GSM Trace is outside of the scope of this specification (see 7). The present document also describes the requirements for the management of Minimization of Drive Tests (MDT)
43、across UMTS networks, EPS networks or 5G networks and Radio Link Failure (RLF) reporting across EPS networks and 5G networks. The present document is built upon the basic Subscriber and UE Trace concept described in clause 4. The high-level requirements for Trace data, Trace Session activation/deact
44、ivation and Trace reporting are defined in clause 5. Clause 5 also contains an overview of use cases for Trace (the use cases are described in Annex A). Clause 6 defines the requirements for managing MDT. Clause 7 defines the requirements for managing RLF reports.Trace control and configuration mana
45、gement are described in 3GPP TS 32.422 2, and Trace data definition and management are described in 3GPP TS 32.423 3. The present document does not cover any Trace capability limitations within a NE (e.g. maximum number of simultaneous traced mobiles for a given NE) or any functionality related to t
46、hese limitations (e.g. NE aborting a Trace Session due to resource limitations). The objectives of the Trace specifications are: a) to provide the descriptions for a standard set of Trace and MDT data; b) to produce a common description of the management technique for Trace, MDT and RLF administrati
47、on and result reporting; c) to define a method for the reporting of Trace, MDT and RLF results across the management interfaces. The following is beyond the scope of the present document, and therefore the present document does not describe: - tracing non-Subscriber or non-UE related events within a
48、n NE; - tracing of all possible parties in a multi-party call (although multiple calls related to the IMSI specified in the Trace control and configuration parameters are traceable). The definition of Trace and MDT data is intended to result in comparability of Trace and MDT data produced in a multi
49、-vendor wireless UMTS, EPS and/or 5G network(s), for those Trace control and configuration parameters that can be standardised across all vendors implementations. Vendor specific extensions to the Trace control and configuration parameters and Trace and MDT data are discussed in 3GPP TS 32.422 2 and 3GPP TS 32.423 3. All functions (trace, MDT etc.) specified in this specification support Network Sharing, with the following conditions: - It is accepted that the recorded information from the shared nodes is available to the Master Operator. Recorded information that i
