Abstract
A base station (BS), a subordinate station (SS) and emergency information transmission methods thereof are provided. The SS is in a power-saving state. The BS shall allocate an emergency alert indicator and emergency information in a transmission channel. The SS in the power-saving state receives the emergency information according to the emergency alert indicator and proceeds with a handshake protocol with the BS to establish an emergency service flow between the BS and the SS.
Claims40
A base station (BS) for transmitting emergency information, wherein the BS is adapted for use in a wireless network and is adapted to be used in conjunction with a backhaul network and a subordinate station (SS) that is in a power-saving state, and the backhaul network is configured to generate the emergency information, the BS comprising:
- a communication interface, being configured to receive the emergency information;
- and
- a processor, being electrically connected to the communication interface and configured to, in response to reception of the emergency information, generate an emergency alert indicator that indicates existence of the emergency information and allocate that the emergency information and the emergency alert indicator are to be transmitted via a broadcast/multicast channel;
- wherein the communication interface is further configured to transmit the emergency information and the emergency alert indicator via the broadcast/multicast channel so that the SS in the power-saving state can obtain the emergency information according to the emergency alert indicator, and the SS is further configured to perform corresponding actions in response to the emergency information.
An emergency information transmission method for a BS, wherein the BS is adapted for use in a wireless network and is adapted to be used in conjunction with a backhaul network and an SS that is in a power-saving state, the backhaul network is configured to generate emergency information, and the BS comprises a communication interface and a processor electrically connected to the communication interface, the emergency information transmission method comprising the following steps of:
- (A) enabling the communication interface to receive the emergency information;
- (B) enabling the processor to, in response to reception of the emergency information, generate an emergency alert indicator that indicates existence of the emergency information;
- (C) enabling the processor to allocate that the emergency information and the emergency alert indicator are to be transmitted via a broadcast/multicast channel;
- and
- (D) enabling the communication interface to transmit the emergency information and the emergency alert indicator via the broadcast/multicast channel so that the SS in the power-saving state can obtain the emergency information according to the emergency alert indicator, and the SS is further configured to perform corresponding actions in response to the emergency information.
An SS for transmitting emergency information, wherein the SS is adapted to be used in conjunction with a BS of a wireless network, the BS is configured to transmit an emergency alert indicator and the emergency information via a broadcast/multicast channel, the emergency alert indicator is configured to indicate existence of the emergency information, and the SS is in a power-saving state and comprises:
- a communication interface, being configured to receive the emergency alert indicator and the emergency information via the broadcast/multicast channel in the power-saving state;
- and
- a processor, being electrically connected to the communication interface and configured to:
- learn about existence of the emergency information from the emergency alert indicator;
- and
- according to the emergency information, execute a handshake protocol with the BS via the communication interface to establish an emergency service flow.
An emergency information transmission method for an SS, wherein the SS is adapted to be used in conjunction with a BS of a wireless network, the BS is configured to transmit an emergency alert indicator and the emergency information via a broadcast/multicast channel, the emergency alert indicator is configured to indicate existence of the emergency information, and the SS is in a power-saving state and comprises a communication interface and a processor electrically connected to the communication interface, the emergency information transmission method comprising the following steps of:
- (A) enabling the communication interface to receive the emergency alert indicator and the emergency information via the broadcast/multicast channel in the power-saving state;
- (B) enabling the processor to learn about existence of the emergency information from the emergency alert indicator;
- and
- (C) enabling the processor to, according to the emergency information, execute a handshake protocol with the BS via the communication interface to establish an emergency service flow.
