31、resent 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 Accessibility 5.1.1.1 Business level requirements If an end user cannot access a ser

32、vice 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. Hence, to have a good accessibility of the services is important from a bu

33、siness 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 covers a wider area than just the E-UTRAN part. Hence it is important to rea

34、lize 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 accessibility. The ser

35、vice 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 an attempt, it shall be considered an attempt first when the eNodeB can be c

36、ertain 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 requester of the E-RAB. The KPI shall be available per QoS group. 5.1.1.3 Use

37、 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 accessibility measurement is not considered OK, then the network operator can investig

38、ate 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 V13.0.0 (2016-02)73GPP TS 32.451 version 13.0.0 Release 135.2 KPI Category Retainabilit

39、y 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 charge for. Also if it happens often that an end-user is interrupted or aborted at

40、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 assists the network operator with information about the retainability provided to

41、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 be limited to the parts that E-UTRAN has control of, i.e. the E-UTRAN KPI shall

42、 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 be E-RAB. Since the keep-alive possibilities of E-RABs, i.e. DRX are availabl

43、e, 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 abnormal (the normal system releases do not exist if keep-alive is set very lo

44、ng). 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 abnormal releases, i.e. abnormal releases per served session time. The KPI shal

45、l 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 investigate which steps that are required to improve the retainability towards t

46、heir 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 user often experiences low quality during use of a service, the end-user might

47、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 operator with information about the integrity provided to their customers. ETSI ETSI TS

Hence it is important to realize that a KPI for this in E-UTRAN shall be limited to the parts that E-UT

49、RAN 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 that impact of file size is excluded. E.g. Curren
