3GPP TS 23502-h20 中英文对照 | 4.15.6.3 Expected UE Behaviour parameters

个人在学习5G标准3GPP TS 23502-h20过程中，也发现google的机器翻译实在晦涩难懂，所以个人在借助百度翻译（中国人更懂中文）的同时，人工对每句话进行了校对。

在自己学习的同时，也将翻译内容分享给给广大网友。由于个人能力有限，翻译不到位的地方还请各位网友们指正。

4.15.6.3 Expected UE Behaviour parameters

These Expected UE Behaviour parameters characterise the foreseen behaviour of a UE or a group of UEs. Sets of these parameters may be provided via the NEF to be stored as part of the subscriber data. Each parameter within the Expected UE Behaviour shall have an associating validity time. The validity time indicates when the Expected UE Behaviour parameter expires and shall be deleted by the related NFs. The validity time may be set to indicate that the particular Expected UE Behaviour parameter has no expiration time. When the validity time expires, the related NFs delete their local copy of the associated Expected UE Behaviour parameter(s). The provision procedure of the Expected UE Behaviour is realized by external parameter provision procedure defined in clause 4.15.6.2.

这些Expected UE Behaviour参数表征了UE或UE组的预期行为。这些参数的集合可以通过NEF提供，以作为订阅者数据的一部分存储。Expected UE Behaviour内的每个参数应具有关联有效时间。有效期表示Expected UE Behaviour参数到期的时间，相关NFs将删除该参数。有效时间可被设置为指示特定Expected UE Behaviour参数没有到期时间。当有效期到期时，相关NFs将删除相关Expected UE Behaviour参数的本地副本。Expected UE Behaviour的提供程序通过第4.15.6.2条中定义的外部参数提供程序实现。

The Expected UE Behaviour parameters stored as AMF-Associated Expected UE Behaviour parameters which is per UE level and SMF-Associated Expected UE Behaviour parameters which is per PDU session level in UDM. AMF retrieves the AMF-Associated Expected UE Behaviour parameters from UDM which may related to both PDU session(s) and SMS transmission. SMF retrieves the SMF-Associated Expected UE Behaviour parameters from UDM for the specific PDU session. AMF and SMF uses the Expected UE Behaviour parameters as described in clause 5.4.6.2 in TS 23.501 [2].

Expected UE Behaviour参数存储为AMF相关的Expected UE Behaviour参数（按UE级别）和SMF相关的Expected UE Behaviour参数（按UDM中的PDU会话级别）。AMF从UDM检索与AMF相关的Expected UE Behaviour参数，该参数可能与PDU会话和SMS传输有关。SMF从UDM检索特定PDU会话的SMF相关Expected UE Behaviour参数。AMF和SMF使用TS 23.501[2]的第5.4.6.2条所述的Expected UE Behaviour参数。

Table 4.15.6.3-1: Description of Expected UE Behaviour parameters

Expected UE Behaviour parameter	Description
Expected UE Moving Trajectory	Identifies the UE's expected geographical movementExample: A planned path of movement
Stationary Indication	Identifies whether the UE is stationary or mobile [optional]
Communication Duration Time	Indicates for how long the UE will normally stay in CM-Connected for data transmission.Example: 5 minutes.[optional]
Periodic Time	Interval Time of periodic communicationExample: every hour.[optional]
Scheduled Communication Time	Time and day of the week when the UE is available for communication.Example: Time: 13:00-20:00, Day: Monday.[optional]
Battery Indication	Identifies power consumption criticality for the UE: if the UE is battery powered with not rechargeable/not replaceable battery, battery powered with rechargeable/replaceable battery, or not battery powered.[optional]
Traffic Profile	Identifies the type of data transmission: single packet transmission (UL or DL), dual packet transmission (UL with subsequent DL or DL with subsequent UL), multiple packets transmission[optional]
Scheduled Communication Type	Indicates that the Scheduled Communication Type is Downlink only or Uplink only or Bi-directional [To be used together with Scheduled Communication Time]Example: <Scheduled Communication Time>, DL only.[optional]
Expected Time and Day of Week in Trajectory	Identifies the time and day of week when the UE is expected to be at each location included in the Expected UE Moving Trajectory.[optional]

The Expected UE Moving Trajectory and the Expected Time and Day of Week in Trajectory may be used by the AMF. All other parameters may be used by the AMF and by the SMF.

AMF可以使用Expected UE Moving Trajectory和Trajectory中的Expected Time和Day of Week。AMF和SMF可使用所有其他参数。

The Scheduled Communication Type and the Traffic Profile should not be used by the AMF to release the UE when NAS Release Assistance Information from the UE is available.

当来自UE的NAS Release Assistance Information可用时，AMF不应使用Scheduled Communication Type和Traffic Profile来释放UE。

In the case of NB-IoT UEs, the parameters may be forwarded to the RAN to allow optimisation of Uu resource allocation for NB-IoT UE differentiation.

在NB-IoT UE的情况下，可以将参数转发给RAN，以允许优化用于NB-IoT UE区分的Uu资源分配。
