Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method, for a user equipment (UE) is disclosed. The method comprises: transmitting, by the UE to a network entity, a registration request message including a registration type information element (IE) indicating a periodic registration updating or a mobility registration updating; receiving, by the UE from the network entity, a registration accept message including a pending network slice selection assistant information (NSSAI); and determining, by the UE, that a previously received allowed NSSAI as invalid based on the registration accept message.
Claims20
A method of a user equipment (UE), the method comprising:
- transmitting, by the UE to a network entity, a registration request message including a registration type information indicating a periodic registration updating or a mobility registration updating;
- receiving, by the UE from the network entity, a registration accept message including a pending network slice selection assistant information (NSSAI) and a registration result information with an indicator indicating a network slice-specific authentication and authorization (NSSAA) is to be performed;
- identifying, by the UE, that a previously received allowed NSSAI as invalid based on the registration accept message;
- and
- initiating, by the UE, a service request procedure in case that the UE in an idle mode obtains an indication that an access stratum connection is established between the UE and the network entity.
A method of a network entity, the method comprising:
- receiving, by the network entity from a user equipment (UE), a registration request message including a registration type information indicating a periodic registration updating or a mobility registration updating;
- and
- transmitting, by the network entity to the UE, a registration accept message to indicate, to the UE, that a previously transmitted allowed network slice selection assistant information (NSSAJ) is invalid, the registration accept message including a pending NSSAI and a registration result information with an indicator indicating a network slice-specific authentication and authorization (NSSAA) is to be performed, wherein a service request procedure is initiated in case that an access stratum connection is established between the UE and the network entity.
A user equipment (UE), the UE comprising:
- a transceiver;
- and
- at least one processor configured to control the transceiver to:
- transmit, to a network entity, a registration request message including a registration type information indicating a periodic registration updating or a mobility registration updating,
- receive, from the network entity, a registration accept message including a pending network slice selection assistant information (NSSAI) and a registration result information with an indicator indicating a network slice-specific authentication and authorization (NSSAA) is to be performed,
- identify that a previously received allowed NSSAI as invalid based on the registration accept message, and
- initiate a service request procedure in case that the UE in an idle mode obtains an indication that an access stratum connection is established between the UE and the network entity.
A network entity, the network entity comprising:
- a transceiver;
- and at least one processor configured to control the transceiver to:
- receive, from a user equipment (UE), a registration request message including a registration type information indicating a periodic registration updating or a mobility registration updating;
- and transmit, to the UE, a registration accept message to indicate, to the UE, that a previously transmitted allowed network slice selection assistant information (NSSAI) is invalid, the registration accept message including a pending NSSAI and a registration result information with an indicator indicating a network slice-specific authentication and authorization (NSSAA) is to be performed, wherein a service request procedure is initiated in case that an access stratum connection is established between the UE and the network entity.
