31、4 KPI overview The following KPI categories are covered by the present document: - Accessibility (see the definition in 1). - Retainability (see the definition in 1). - Integrity (see the definition in 1). - Availability - Mobility 5 Requirements 5.1 KPI Category “Accessibility” 5.1.1 E-RAB Accessib
32、ility 5.1.1.1 Business level requirements If an end user cannot access a service it is hard to charge for the service. Also, if it happens often that an end-user cannot access the provided service, the end-user might change wireless subscription provider, i.e. loss of income for the network operator
33、. Hence, to have a good accessibility of the services is important from a business point of view. This measurement assists the network operator with information about the accessibility provided to their customers. 5.1.1.2 Specification level requirements The accessibility of an end-user application
34、covers a wider area than just the E-UTRAN part. Hence it is important to realize that a KPI for this in E-UTRAN shall be limited to the parts that E-UTRAN has control of, i.e. the E-UTRAN KPI shall be defined so that it indicates the E-UTRAN contribution to the end-user impact, NOT attempt to take r
35、esponsibility of the whole end-to-end part of service accessibility. The service provided by E-UTRAN for this KPI shall be E-RAB. It shall be possible to measure the accessibility of E-RABs in E-UTRAN. Accessibility measurement should be available as a success rate for the attempts. As for defining
36、an attempt, it shall be considered an attempt first when the eNodeB can be certain that is a request for an E-RAB. As for defining a success, it shall be considered a success when the eNodeB have completed its task to setup resources and the result of the E-RAB establishment can be informed to the r
37、equester of the E-RAB. The KPI shall be available per QoS group. 5.1.1.3 Use case description In providing end-user services to wireless end-users, the first step is to get access to the wireless service. First after access to the service has been performed, the service can be used. If an accessibil
38、ity measurement is not considered OK, then the network operator can investigate which steps that are required to improve the accessibility towards their customers. This measurement should be used for observing the impact of E-UTRAN on end-users service accessibility. ETSI ETSI TS 132 451 V14.0.0 (20
39、17-04)73GPP TS 32.451 version 14.0.0 Release 145.2 KPI Category “Retainability” 5.2.1 E-RAB Retainability 5.2.1.1 Business level requirements If an end user is interrupted often during use of a service, or the service is aborted during use, the time the service is not provided could be hard to charg
40、e for. Also if it happens often that an end-user is interrupted or aborted at service use it might change wireless subscription provider, i.e. loss of income for the network operator. Hence to have a good retainability of the services is important from a business point of view. This measurement assi
41、sts the network operator with information about the retainability provided to their customers. 5.2.1.2 Specification level requirements The retainability of an end-user application covers a wider area than just the E-UTRAN part. Hence it is important to realize that a KPI for this in E-UTRAN shall b
42、e limited to the parts that E-UTRAN has control of, i.e. the E-UTRAN KPI shall be defined so that it indicates the E-UTRAN contribution to the end-user impact, NOT attempt to take responsibility of the whole end-to-end part of service retainability. The service provided by E-UTRAN for this KPI shall
43、 be E-RAB. Since the keep-alive possibilities of E-RABs, i.e. DRX are available, it is probable that E-RABs are kept alive much longer than they are used for transmitting data. With an extreme setting of this keep-alive functionality it can lead to that basically all E-RAB releases are doomed to be
44、abnormal (the normal system releases do not exist if keep-alive is set very long). Hence the definition is to only count it as abnormal releases when there was actually an impact on the end-user. The preferred normalization of abnormal releases of the service shall be time unit of transfer between a
45、bnormal releases, i.e. abnormal releases per served session time. The KPI shall be available per QoS group. 5.2.1.3 Use case description When a service is used it is important that it is not interrupted or aborted. If a retainability measurement is not considered OK, then the network operator can in
46、vestigate which steps that are required to improve the retainability towards their customers. This measurement should be used for observing the impact of E-UTRAN on end-users service retainability. 5.3 KPI Category “Integrity” 5.3.1 E-UTRAN IP Throughput 5.3.1.1 Business level requirements If an end
47、 user often experiences low quality during use of a service, the end-user might change wireless subscription provider, i.e. loss of income for the network operator. Hence to have a good integrity of the services is important from a business point of view. This measurement assists the network operato
48、r with information about the integrity provided to their customers. ETSI ETSI TS 132 451 V14.0.0 (2017-04)83GPP TS 32.451 version 14.0.0 Release 145.3.1.2 Specification level requirements The integrity of an end-user application covers a wider area than just the E-UTRAN part. Hence it is important t
49、o realize that a KPI for this in E-UTRAN shall be limited to the parts that E-UTRAN has control of, i.e. the E-UTRAN KPI shall be defined so that it indicates the E-UTRAN contribution to the end-user impact, NOT attempt to take responsibility of the whole end-to-end part of service integrity. The service provided by E-UTRAN for this KPI shall be delivery of IP packets. To make the measurement on a Black Box level for the eNB it should be measured on IP level (i.e. volume part in throughput measurement shall be IP volume). The measurements shall be defined so
