Abstract
A method and apparatus for restricting a frequency in a wireless communication system is provided. A user equipment (UE) receives restriction information and a timer value from a network, starts a timer based on the timer value, and restricts usage of a frequency based on the restriction information.
Claims14
A method for restricting a frequency in a wireless communication system, the method performed by a first user equipment (UE) and comprising:
- receiving restriction information from a 3rd generation partnership project (3GPP) access network, the information including an unusable frequency for a wireless network local area network (WLAN) and a timer value;
- starting a timer based on the timer value;
- and
- offloading traffic from the 3GPP access network to the WLAN based on the restriction information and the timer,
- wherein use of the unusable frequency is restricted while the offloading is performed and the timer is running.
2 more elements
A first user equipment (UE) for restricting a frequency in a wireless communication system, the UE comprising:
- a radio frequency (RF) unit configured to transmit or receive a radio signal;
- and
- a processor coupled to the RF unit, and configured to:
- control the RF unit to receive restriction information from a 3rd generation partnership project (3GPP) access network, the information including an unusable frequency for a wireless network local area network (WLAN) and a timer value;
- start a timer based on the timer value;
- and
- offload traffic from the 3GPP access network to the WLAN based on the restriction information and the timer,
- wherein use of the unusable frequency is restricted while the offloading is performed and the timer is running.
