Claim 13:
14. A network access device, comprising:
a processor;
memory for storing a computer program executable by the processor;
wherein the processor is configured to:
determine at least one candidate alert sequence and allocating at least one uplink grant-free transmission resource for the at least one candidate alert sequence, wherein the at least one candidate alert sequence is a group of sequences predefined by the network access device;
transmit a notification message to a terminal to enable the terminal to select a target alert sequence from the at least one candidate alert sequence; wherein the notification message comprises the at least one candidate alert sequence and indication information of the at least one uplink grant-free transmission resource allocated for the at least one candidate alert sequence, and in transmitting the notification message to a terminal, the processor is further configured to: carry the notification message in a broadcast message, or carrying the notification message in an uplink grant-free transmission resource configuration message;
receive the target alert sequence from the terminal;
determine whether a first uplink grant-free transmission resource corresponding to the target alert sequence is occupied;
transmit a collision indication to the terminal in response to that the first uplink grant-free transmission resource is occupied, wherein the collision indication is configured to notify the terminal that the first uplink grant-free transmission resource corresponding to the target alert sequence is occupied; and
receive uplink data from the terminal by using a transmission resource different from the first uplink grant-free transmission resource.
