Title: DEVICE AND METHOD OF HANDLING NETWORK SLICE INFORMATION
Abstract: A communication device for handling network slice information comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The storage device stores, and the processing circuit is configured to execute instructions of entering a RRC_CONNECTED state and establishing a RRC connection to a network; receiving a first RRC message on the RRC connection from the network, wherein the first RRC message suspends the RRC connection or configures the communication device to enter a RRC_INACTIVE state; performing a RRC procedure with the network to resume the RRC connection or transferring to the RRC_CONNECTED state from the RRC_INACTIVE state; and transmitting a second RRC message of the RRC procedure to the network, wherein the second RRC message comprises network slice information.
