31、421: “Subscriber and equipment trace: Trace concepts and requirements“; TS 32.422: “Subscriber and equipment trace: Trace control and configuration management“; TS 32.423: “Subscriber and equipment trace: Trace data definition and management“; Subscriber and equipment trace provide very detailed inf

32、ormation at call level on one or more specific mobile(s). This data is an additional source of information to Performance Measurements and allows going further in monitoring and optimisation operations. Contrary to Performance measurements, which are a permanent source of information, trace is activ

33、ated 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 cause of a malfunctioning mobile, advanced troubleshooting, optimisation of resource usage and quality, RF coverage control and capacity improveme

34、nt, dropped call analysis, Core Network and UTRAN end-to-end UMTS procedure validation. The capability to log data on any interface at call level for a specific 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 fr

35、om Performance measurements such as perception of end-user QoS during his call (e.g. requested QoS vs. provided QoS), correlation between protocol messages and RF measurements, or interoperability with specific mobile vendors. Moreover, performance measurements provide values aggregated on an observ

36、ation period; Subscriber and UE Trace give instantaneous values for a specific event (e.g. call, location update, etc.). If performance measurements are mandatory for daily operations, future network planning and primary trouble shooting; Subscriber and UE Trace is the easy way to go deeper into inv

37、estigation and UMTS network optimisation. In order to produce this data, Subscriber and UE Trace are carried out in the NEs, which comprise the network. The data can then be transferred to an external system (e.g. an Operations System (OS) in TMN terminology, for further evaluation). ETSI ETSI TS 13

38、2 421 V14.0.0 (2017-04)73GPP TS 32.421 version 14.0.0 Release 141 Scope The present document describes the requirements for the management of Trace and the reporting of Trace data (including FDD mode and TDD mode) across UMTS networks or EPS networks as it refers to subscriber tracing (tracing of IM

39、SI 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 cells (Cell Traffic Trace). The present document also includes the description of Service Level Tracing (tracing of a specific service). It d

40、efines the administration of Trace Session activation/deactivation by the Element Manager (EM), the network or User Equipment (UE) itself via signalling, the generation of Trace results in the Network Elements (NEs) and UE and the transfer of these results to one or more Operations Systems, i.e. EM(

41、s) and/or Network Manager(s) (NM(s). 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) across UMTS networks or EPS networks and Radio Link Failure (RLF) reporting across EPS ne

42、tworks. 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/deactivation and Trace reporting are defined in clause 5. Clause 5 also contains an overview of use cases for Trace (the us

43、e 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 management are described in 3GPP TS 32.422 2, and Trace data definition and management are described in 3GPP TS 32.423 3.

44、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 these limitations (e.g. NE aborting a Trace Session due to resource limitations). The objectives of the Trace specifica

45、tions 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 administration and result reporting; c) to define a method for the reporting of Trace, MDT and RLF results across the management i

46、nterfaces. 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 an NE; - tracing of all possible parties in a multi-party call (although multiple calls related to the IMSI specified i

47、n 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-vendor wireless UMTS and/or EPS network(s), for those Trace control and configuration parameters that can be standard

48、ised 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 follo

49、wing conditions: - It is accepted that the recorded information from the shared nodes is available to the Master Operator. Recorded information that is collected in a non shared node or cell will only be available to the operator managing the non shared node or cell. - It is accepted that the recorded information from the shared network shall be delivered to the Participating Operator whose PLMN recording is requested, taking user consent into account. Operators must also agree on sharing the information, but how that agreement is done is outside the scope of this
