34、) 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 network or user view. c) Logical formula definition (Mandatory):

35、 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 KPI“s logical formula is the successful event divided by all event. d) Physical formula defin

36、ition (Optional): This field should contain the KPI formula description using the 3GPP defined counter names. ETSI ETSI TS 132 450 V13.0.0 (2016-02)73GPP TS 32.450 version 13.0.0 Release 13This field can be used only if the counters needed for the KPI formula is defined in any of the 3GPP TS for per

This section can be filled out only when the underlying m

38、easurements 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; GERAN; CS core; PS core; IMS; E-UTRAN. The field can have multiple

39、 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 h) Unit of the KPI (mandatory) This section describes the unit of the KPI

40、. 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 following: MEAN: This KPI is produced to reflect a mean measurement value based on a nu

41、mber 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) Remark: (Optional) This field is for any further information that is needed for the KP

42、I 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.

47、rds E-RABs Operator Service E-RAB mapping A X Initial E-RABA Y Initial E-RAB B X Initial E-RABB Y Added E-RAB To provide Accessibility measurement from E-UTRAN that can be mapped to a service for the operator the following measurements are defined: A1: Initial E-RAB establishment success rate A2: Ad

48、ded 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 is required compared with the QoS characteristic provided by an existing Initial E-RAB, a

49、n 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 = A1*A2*100 % 6.2 KPI Category “Retainability
