Method and UE for determining request for resources from network apparatus in wireless network
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments disclosed herein relate to a method for determining request for resources from a network apparatus in a wireless network by a first UE of a multi-USIM UE. The method includes determining that the first UE of the multi-USIM UE need to request for resources from the network apparatus in the wireless network to transmit pending uplink data to the network apparatus or receive pending downlink data from the network apparatus.
1 . A method performed by a user equipment (UE) supporting a multi-universal subscriber identity module (MUSIM) in a wireless network, the method comprising:
determining whether to request a network to release a non-access stratum (NAS) signalling connection;
setting a request type to a NAS signalling connection release in a UE request type information element (IE) of a NAS message, in case that the UE determines to request the network to release the NAS signalling connection; and
transmitting, to a network apparatus, the NAS message with the request type being set to the NAS signalling connection release in the UE request type IE,
wherein a follow-on request indicator is set to a no follow-on request pending in the NAS message, in case that a release of the NAS signalling connection is requested.
2 . The method of claim 1 , wherein at least one of an uplink data status IE or an allowed protocol data unit (PDU) session status IE is not included in the NAS message, in case that the release of the NAS signalling connection is requested.
3 . The method of claim 1 , wherein active status information is not included in the NAS message, in case that the release of the NAS signalling connection is requested.
4 . The method of claim 1 , further comprising:
determining an update of new paging restriction information is needed during while the UE is in an idle state or an inactive state,
wherein the UE waits to update the new paging restriction information until a new NAS procedure is triggered.
5 . The method of claim 4 , further comprising:
determining whether the new NAS procedure is triggered due to a first reason different from a second reason for updating paging restriction information; and
transmitting a new NAS message including the new paging restriction information based on the new NAS procedure.
6 . The method of claim 1 , further comprising:
in case that the UE wants to update paging restriction information, initiating a first NAS procedure with the follow-on request indicator being set to a follow-on request pending; and
not releasing a NAS signaling connection after a completion of the first NAS procedure; and
transmitting a new NAS message including the paging restriction information and the request type being set to the NAS signalling connection release in the UE request type IE after the completion of the first NAS procedure.
7 . A user equipment (UE) supporting multi-universal subscriber identity module (MUSIM) in a wireless network, the UE comprising:
a transceiver; and
a processor configured to:
determine whether to request a network to release a non-access stratum (NAS) signalling connection,
set a request type to a NAS signalling connection release in a UE request type information element (IE) of a NAS message in case that the UE determines to request the network to release the NAS signalling connection, and
transmit, to a network apparatus via the transceiver, the NAS message with the request type being set to the NAS signalling connection release in the UE request type IE,
wherein a follow-on request indicator is set to a no follow-on request pending in the NAS message, in case that a release of the NAS signalling connection is requested.
8 . The UE of claim 7 , wherein at least one of an uplink data status IE or an allowed protocol data unit (PDU) session status IE is not included in the NAS message, in case that the release of the NAS signalling connection is requested.
9 . The UE of claim 7 , wherein active status information is not included in the NAS message, in case that the release of the NAS signalling connection is requested.
10 . The UE of claim 7 , wherein the processor is further configured to:
determine an update of new paging restriction information is needed while the UE is in an idle state or an inactive state,
wherein the UE waits to update the new paging restriction information until a new NAS procedure is triggered.
11 . The UE of claim 10 , wherein the processor is further configured to:
determine whether the new NAS procedure is triggered due to a first reason different from a second reason for updating paging restriction information, and
transmit a new NAS message including the new paging restriction information based on the new NAS procedure.
12 . The UE of claim 7 , wherein the processor is configured to:
in case that the UE wants to update paging restriction information, initiate a first NAS procedure with the follow-on request indicator being set to a follow-on request pending, and
not release a NAS signaling connection after a completion of the first NAS procedure, and
transmit a new NAS message including the paging restriction information and the request type being set to the NAS signalling connection release in the UE request type IE after the completion of the first NAS procedure.
13 . A method of a network apparatus in a wireless network, the method comprising:
receiving, from a user equipment (UE) supporting a multi-universal subscriber identity module (MUSIM), a non-access stratum (NAS) message with a request type being set to a NAS signalling connection release in a UE request type information element (IE); and
processing the NAS message,
wherein a follow-on request indicator is set to a no follow-on request pending in the NAS message, in case that a release of the NAS signalling connection is requested.
14 . The method of claim 13 , wherein at least one of an uplink data status IE, an allowed protocol data unit (PDU) session status IE, or an active status IE is not included in the NAS message, in case that the release of the NAS signalling connection is requested.
15 . The method of claim 13 , wherein, in case that the UE waits to update new paging restriction information until a new NAS procedure is triggered and the new NAS procedure is triggered due to a first reason different from a second reason for updating the new paging restriction information, a NAS message including the new paging restriction information is received from the UE.
16 . The method of claim 13 , wherein, in case that the UE wants to update paging restriction information, a first NAS procedure is initiated with the follow-on request indicator being set to a follow-on request pending,
wherein a NAS signaling connection is not released after a completion of the first NAS procedure, and
wherein a new NAS message including the paging restriction information and a release request indication is received from the UE after the completion of the first NAS procedure.
17 . A network apparatus in a wireless network, the network apparatus comprising:
a transceiver; and
a processor configured to
receive, via the transceiver from a user equipment (UE) supporting a multi-universal subscriber identity module (MUSIM), a non-access stratum (NAS) message with a request type being set to a NAS signalling connection release in a UE request type information element (IE), and
process the NAS message,
wherein a follow-on request indicator is set to a no follow-on request pending in the NAS message, in case that a release of the NAS signalling connection is requested.
18 . The network apparatus of claim 17 , wherein at least one of an uplink data status IE, an allowed protocol data unit (PDU) session status IE, or an active status IE is not included in the NAS message, in case that the release of the NAS signalling connection is requested.
19 . The network apparatus of claim 17 , wherein, in case that the UE waits to update new paging restriction information until a new NAS procedure is triggered and the new NAS procedure is triggered due to a first reason different from a second reason for updating the new paging restriction information, a NAS message including the new paging restriction information is received from the UE.
20 . The network apparatus of claim 17 , wherein, in case that the UE wants to update paging restriction information, a first NAS procedure is initiated with the follow-on request indicator being set to a follow-on request pending,
wherein a NAS signaling connection is not released after a completion of the first NAS procedure, and
wherein a new NAS message including the paging restriction information and a release request indication is received from the UE after the completion of the first NAS procedure.
