Abstract: A method of controlling a backoff timer at a user equipment (UE) configured for dual priority, the method includes transmitting a non access stratum (NAS) request message without an access point name (APN) including a low priority indicator set to a first value to a network node, wherein the first NAS request message without the APN is an attach request message transmitted along with a packet data network (PDN) connectivity request without the APN; receiving a reject message for the NAS request message from the network node, and wherein a cause in the reject message is set to insufficient resources; setting the low priority indicator to a second value; and initiating a new attach procedure without the APN, while a session management (SM) backoff timer is running, wherein the first value of the low priority indicates that the UE is configured for NAS signaling low priority.

Abstract: One disclosure of the present specification provides a method for using packet switching (PS) data off function in user equipment (UE). The method can comprise the steps of: determining whether a session management (SM) delay time timer or a mobility management (MM) delay time timer is being operated, in a state in which the transmission of a non-access stratum (NAS) request message for an SM is required according to a request for the activation or the inactivation of the PS data off function; and, according to the result of the determination, allowing an NAS layer of the UE to include activation or inactivation state information of the PS data off function in the NAS request message for an SM and transmit the same.
