Bộ đếm và Tài nguyên mạng Các phép đo vật lý đã được xác định phải luôn luôn đại diện cho một bộ sưu tập các quầy liên quan đến một nguồn tài nguyên mạng (Mục 7.1.1.3). Các ví dụ phổ biến nhất của một nguồn tài nguyên mạng là UtranCell. Những người khác là RNC hoặc một giao diện được định nghĩa | Radio Network Optimisation Process 429 Counters and Network Resources The defined physical measurements must always represent a collection of counters in relation to a network resource Section 7.1.1.3 . The most common example of a network resource is the UtranCell. Others are the RNC or a defined interface Iub Iur Iu . Before collecting the counters from the network and using them in making the right measurements one characteristic of the radio access network must be noted and also shown in the measurements. This is the role of an RNC which can act as an Serving RNC SRNC Drift RNC DRNC or Controlling RNC CRNC . Some measurements are carried out in a CRNC and the counters are also separated for SRNC and DRNC. These measurements are currently L3 signalling at Iub Iur soft handover intra-system handover traffic. Other measurements are also carried out in a CRNC but counter separation into SRNC or DRNC is not needed. These measurements are currently L3 signalling at Iu RRC signalling cell resource. Some measurements are carried out in an SRNC. These are currently service level measurements. Figure 7.22 presents a view of the radio network measurements obtained from a radio access network. Naming of the Counters Every measurement must have a unique identifier - e.g. M1000C1. This means that only one object in the network can own the measurement in question and only one measurement type under that object can have that name. Other relevant information depends on the usage of the measurement. Information common to all counters is the counter name reason for update and dependences on other counters. For fast and network-wide follow-up optimisation counter names should correspond to standardised names and terms - one naming convention is introduced in 16 . Reason for Counter Triggering All measurement descriptions should include a sufficiently detailed description of the reason or condition for the update - e.g. signalling-related failure policy decision together with .
