Narrowband internet of things system and self-optimization network information transmission method thereof

A self-optimization network information transmission method for a first base station, the first base station being for communicating with a user equipment (UE) used in an internet of things network system, the method comprising:

• transmitting, by the first base station, a configuration to the UE, wherein the configuration comprises an indicator indicating to the UE whether to transmit self-optimization network information to the first base station in response to receiving a corresponding self-optimization network parameter from a second base station or in response to expiration of a timer included in the configuration;
• resuming or establishing a connection between the UE and the first base station;
• and
• receiving via the connection, by the first base station, a self-optimization network information from the UE in a first early data transmission message, based on the configuration, in response to a selection by the UE based at least in part on the indicator, the selection comprising at least one of:
• receiving the self-optimization network parameter from the second base station or expiration of the timer, wherein the self-optimization network parameter comprises at least one of a global cell identification of the second base station and a physical cell identification of the second base station received from the second base station via a broadcast channel of the second base station;
• wherein:
• the configuration is for the UE to transmit the self-optimization network information by:
• transmitting the self-optimization network information to the first base station after receiving a self-optimization network parameter from the second base station, wherein the self-optimization network information comprises the self-optimization network parameter of the second base station;
• transmitting, in response to self-optimization network information corresponding to the self-optimization network parameter being available or in response to expiration of the timer, the self-optimization network information to the first base station;
• and
• transmitting a second early data transmission message to the first base station with a self-optimization network information available message embedded in the second early data transmission message, the second early data transmission message comprising a mobile-original early data transmission message;
• and
• transmitting the self-optimization network information further comprises:
• transmitting the self-optimization network information to the first base station based on the configuration and the self-optimization network information available message.

A user equipment (UE) for use in an internet of things (IoT) network, the UE comprising:

• a memory;
• and
• at least one processor coupled with the memory and configured to cause the UE to:
• receive a configuration from a first base station, wherein the configuration comprises an indicator indicating to the UE whether to transmit self-optimization network information to the first base station in response to receiving a corresponding self-optimization network parameter from a second base station or in response to expiration of a timer included in the configuration;
• receive the self-optimization network parameter from the second base station via a broadcast channel of the second base station, wherein the self-optimization network parameter comprises at least one of a global cell identification of the second base station and a physical cell identification of the second base station received from the second base station via the broadcast channel of the second base station;
• resume or establish a connection between the UE and the first base station;
• determine, based at least in part the configuration from the first base station, whether to transmit self-optimization network information in response to receiving a corresponding self-optimization network parameter from the second base station or in response to expiration of a timer included in the configuration;
• and
• transmit, via the connection, the self-optimization network information to the first base station in a first early data transmission message, based on the configuration, in response to one of:
• receiving the self-optimization network parameter from the second base station or expiration of the timer, by:
• transmitting the self-optimization network information to the first base station after receiving the self-optimization network parameter from the second base station, wherein the self-optimization network information comprises the self-optimization network parameter of the second base station;
• transmitting, in response to self-optimization network information corresponding to the self-optimization network parameter received via the broadcast channel being available or in response to expiration of the timer, the self-optimization network information to the first base station;
• and
• transmitting a second early data transmission message to the first base station with a self-optimization network information available message to the first base station embedded in the second early data transmission message, the second early data transmission message comprising a mobile-original early data transmission message,
• wherein transmitting the self-optimization network information further comprises:
• transmitting the self-optimization network information to the first base station based on the configuration and the self-optimization network information available message.
