34、 in 1). - Availability - Mobility 5 KPI Definitions Template a) Long name (Mandatory): This field shall contain the long and descriptive name of the KPI. b) Description (Mandatory): This field shall contain the description of the KPI. Within this field it should be given if the KPI is focusing on ne
35、twork or user view. c) Logical formula definition (Mandatory): The logical formula should describe what the KPI formula is in logical way. The description of the formula is given in a written textual format without any measurement or counter names. E.g. a success rate KPIs logical formula is the suc
36、cessful event divided by all event. d) Physical formula definition (Optional): This field should contain the KPI formula description using the 3GPP defined counter names. This field can be used only if the counters needed for the KPI formula is defined in any of the 3GPP TS for ETSI ETSI TS 132 450

38、PI. This section can be filled out only when the underlying measurements for the KPI formula can be defined, i.e. physical formula definition is available. f) KPI Object (mandatory) This section shall describe the object of the KPI. The object of the KPI is one or some of the following: - UTRAN; - G
39、ERAN; - CS core; - PS core; - IMS; - E-UTRAN. The field can have multiple selection, e.g. for a network level end to end KPI the selection can be UTRAN+PS core network. g) KPI category (mandatory) This section contains the classification of the KPI into one of the KPI categories listed in section 4
40、h) Unit of the KPI (mandatory) This section describes the unit of the KPI. The unit can be one of the following: - percentage; - time interval (second or millisecond); - Erlang; - kbit/s. i) Type of the KPI (Mandatory) This section describes the type of the KPI. The KPI type can be one of the follow
41、ing: - MEAN: This KPI is produced to reflect a mean measurement value based on a number of sample results. - RATIO: KPI is produced to reflect the percentage of a specific case occurrence to all the cases. - CUM: This KPI is produced to reflect a cumulative measurement which is always increasing. j)
42、 Remark: (Optional) This field is for any further information that is needed for the KPI definition. Here it is proposed to define any additional information that would be needed for the KPI definition; e.g. the definition of a call in UTRAN. ETSI ETSI TS 132 450 V14.0.0 (2017-04)83GPP TS 32.450 ver

48、 following measurements are defined: A1: Initial E-RAB establishment success rate A2: Added E-RAB establishment success rate The establishment success rate is defined as: Services can be mapped towards either Initial or Added E-RABs depending on operator strategy. If a different QoS characteristic i
49、s required compared with the QoS characteristic provided by an existing Initial E-RAB, an Added E-RAB can be requested. QoS characteristics can be defined on an E-RAB basis; hence both Initial E-RAB establishment success rate (A1) and Added E-RAB establishment success rate (A2) shall be available per QoS group. With these two measures the operator can calculate the service accessibility depending on E-RAB mapping as follows: Service mapped on Initial E-RAB = A1*100 % Service mapped on Added E-RAB
