31、MO-LR Mobile Originated Location Request MT-LR Mobile Terminated Location RequestNAS Non-access Stratum UE User Equipment 4 General 4.1 Overview 4.1.1 NAS aspect To enable transfer of application protocol messages between the MME and the UE, a generic “container“ message is defined on the downlink (

32、Downlink Generic NAS Transport message) and the uplink (Uplink Generic NAS Transport message). The message protocol and procedures are described in 3GPP TS 24.301 3. 4.1.2 LCS aspect Location Services (LCS) uses the generic containers provided by the NAS Generic Transport mechanism to transfer LCS s

33、ignalling messages between the UE and the network. Currently, container in the generic transport messages can carry the following LCS information: - LTE Positioning Protocol (LPP) messages (Refer to 3GPP TS 36.355 4) - Both downlink and uplink LPP messages are supported - A Routing Identifier is tra

34、nsported as the Additional Information IE in Uplink/Downlink Generic NAS Transport message for LPP messages (Refer to 3GPP TS 24.301 3) - Location services messages - Messages for MO-LR operations (Refer to 3GPP TS 24.080 5) - Messages for MT-LR LCS location notification (Refer to 3GPP TS 24.080 5)

35、4.2 LCS Support capabilities 4.2.1 UE support of LCS The UE announces to the network its ability to support LCS notification mechanism and/or LPP messages using the UE Network Capability IE defined in 3GPP TS 24.301 3. ETSI ETSI TS 124 171 V14.0.0 (2017-03)73GPP TS 24.171 version 14.0.0 Release 144.

36、2.2 MME support of LCS The network announces to the UE its ability to support LCS MO-LR mechanism in E-UTRAN and GERAN/UTRAN using the EPS network feature support IE defined in 3GPP TS 24.3013. These information are taken into account by the UE, in addition to UEs LCS and CSFB capabilities for UE to

37、 determine whether to initiate EPC-MO-LR procedure or CS fallback procedure for CS-MO-LR in GERAN/UTRAN as specified in 3GPP TS 23.272 8, subclause 8.3.1. 5 Support of LCS signaling 5.1 General This clause defines the E-UTRAN LCS operations (subclause 5.2) and the format and coding of the messages (

38、subclause 5.3). The messages defined in this subclause can be transported in the Downlink Generic NAS Transport message and the Uplink Generic NAS Transport message defined in 3GPP TS 24.301 3. 5.2 LCS operations 5.2.0 General The operations defined in this subclause are for E-UTRAN LCS support only

39、. The MO-LR operation and the Location Notification operation for E-UTRAN LCS are similar to that for GERAN and UTRAN LCS. The operations for GERAN and UTRAN location signalling support are defined in 24.030 6. 5.2.1 Network initiated location services operations 5.2.1.1 Location Notification 5.2.1.

40、1.0 General The Location Notification operation enables the MME to trigger the end-user notification verification process on the UE using NAS signaling. The NAS signaling (see 5.2.1.1.1) are transported using the Downlink Generic NAS Transport message and the Uplink Generic NAS Transport message def

41、ined in 3GPP TS 24.301 3. Figure 5.2.1.1.0-1 illustrates an example of the NAS signaling transport for an EPC-MT-LR session.

42、nal Information IE of the Downlink/Uplink Generic NAS Transport message is not used when the LCS Location Notification signaling are transported in the Generic Message Container. 5.2.1.1.1 Normal operation The network invokes a location notification procedure by sending a REGISTER message containing

43、 a LCS-LocationNotification invoke component to the UE. This may be sent either to request verification for MT-LR or to notify about already authorized MT-LR. In case of privacy verification the UE shall respond to the request by sending a RELEASE COMPLETE message containing the mobile subscribers r

44、esponse in a return result component (see figure 5.2.1.1.1-1). If the timer T(LCSN) expires in the network before any response from the UE (e.g. due to no response from the user), the network shall interpret this by applying the default treatment defined in TS 3GPP 23.271 2 (i.e. disallow location i

45、f barred by subscription and allow location if allowed by subscription). In the case of location notification no response is required from the UE, the UE shall terminate the dialogue by sending a RELEASE COMPLETE message containing a LocationNotification return result. If the UE is unable to process

46、 the request received from the network, it shall return an error indication by sending a RELEASE COMPLETE message containing a return error component. Error values are specified in 3GPP TS 24.080 5. ETSI ETSI TS 124 171 V14.0.0 (2017-03)93GPP TS 24.171 version 14.0.0 Release 14UE Network REGISTER Fa
