Abstract

Presented are systems and methods for non-public network (NPN) measurement. A wireless communication node may send a first radio resource configuration (RRC) message including a first configuration that includes an indication of a non-public network (NPN) scope of first measurement to be performed by a wireless communication device to the wireless communication device. The wireless communication node may cause the wireless communication device to perform the first measurement according to the NPN scope.

Claims (36)

1 . A method, comprising:

sending, by a wireless communication node to a wireless communication device, a first radio resource configuration (RRC) message including a second minimization of drive test (MDT) configuration based on a next generation application protocol (NGAP) message received by the wireless communication node from an access and mobility management function (AMF), the NGAP message providing a first MDT configuration, wherein the second MDT configuration includes an indication of a non-public network (NPN) scope of MDT measurement to be performed by the wireless communication device; and

causing the wireless communication device to perform the MDT measurement according to the NPN scope.

2 . The method of claim 1 , wherein the NPN scope comprises at least one of:

a list of identifiers of stand-alone non-public networks (SNPNs), to indicate SNPNs allowed for the MDT measurement; or

a list of identifiers of closed access groups (CAGs), to indicate public network integrated non-public networks (PNI-NPNs) allowed for the MDT measurement.

3 . The method of claim 1 , comprising:

receiving, by the wireless communication node from the wireless communication device, a second RRC message comprising a result of the MDT measurement, the MDT measurement performed according to the NPN scope.

4 . A method, comprising:

receiving, by a wireless communication device from a wireless communication node, a first radio resource configuration (RRC) message including a second minimization of drive test (MDT) configuration based on a next generation application protocol (NGAP) message received by the wireless communication node from an access and mobility management function (AMF), the NGAP message providing a first MDT configuration, wherein the second MDT configuration includes an indication of a non-public network (NPN) scope of MDT measurement; and

performing, by the wireless communication device, the MDT measurement according to the NPN scope.

5 . The method of claim 4 , wherein the NPN scope comprises at least one of:

a list of identifiers of stand-alone non-public networks (SNPNs), to indicate SNPNs allowed for the MDT measurement; or

a list of identifiers of closed access groups (CAGs), to indicate public network integrated non-public networks (PNI-NPNs) allowed for the MDT measurement.

6 . The method of claim 4 , wherein performing the MDT measurement according to the NPN scope comprises: performing the MDT measurement within an area indicated by the NPN scope.

7 . The method of claim 4 , comprising:

sending, by the wireless communication device to the wireless communication node, a second RRC message comprising a result of the MDT measurement, the MDT measurement performed according to the NPN scope.

8 . A wireless communication node, comprising:

at least one processor configured to:

send, via a transmitter to a wireless communication device, a first radio resource configuration (RRC) message including a second minimization of drive test (MDT) configuration based on a next generation application protocol (NGAP) message received by the wireless communication node from an access and mobility management function (AMF), the NGAP message providing a first MDT configuration, wherein the second MDT configuration includes an indication of a non-public network (NPN) scope of MDT measurement to be performed by the wireless communication device,

wherein the wireless communication device performs the MDT measurement according to the NPN scope.

9 . The wireless communication node of claim 8 , wherein the NPN scope comprises at least one of:

a list of identifiers of stand-alone non-public networks (SNPNs), to indicate SNPNs allowed for the MDT measurement; or

a list of identifiers of closed access groups (CAGs), to indicate public network integrated non-public networks (PNI-NPNs) allowed for the MDT measurement.

10 . The wireless communication node of claim 8 , wherein the at least one processor is configured to:

receive, via a receiver from the wireless communication device, a second RRC message comprising a result of the MDT measurement, the MDT measurement performed according to the NPN scope.

11 . A wireless communication device, comprising:

at least one processor configured to:

receive, via a receiver a from a wireless communication node, a first radio resource configuration (RRC) message including a second minimization of drive test (MDT) configuration based on a next generation application protocol (NGAP) message received by the wireless communication node from an access and mobility management function (AMF), the NGAP message providing a first MDT configuration, wherein the second MDT configuration includes an indication of a non-public network (NPN) scope of MDT measurement; and

perform the MDT measurement according to the NPN scope.

12 . The wireless communication device of claim 11 , wherein the NPN scope comprises at least one of:

a list of identifiers of stand-alone non-public networks (SNPNs), to indicate SNPNs allowed for the MDT measurement; or

a list of identifiers of closed access groups (CAGs), to indicate public network integrated non-public networks (PNI-NPNs) allowed for the MDT measurement.

13 . The wireless communication device of claim 11 , wherein the at least one processor is configured to perform the MDT measurement within an area indicated by the NPN scope.

14 . The wireless communication device of claim 11 , wherein the at least one processor is configured to:

send, via a transmitter to the wireless communication node, a second RRC message comprising a result of the MDT measurement, the MDT measurement performed according to the NPN scope.
