Abstract
An apparatus and method for handling network loss in a wireless access system includes determining whether network loss has occurred or not and, if a Mobile Station (MS) attempts an entry in which the network loss has occurred, transmitting one of a first message including information associated with prohibiting new entry and a second message including information associated with informing that a supported service is restricted.
Claims9
A method for operating a base station (BS) in a wireless access system, the method comprising:
- detecting a backhaul network loss;
- transmitting a first message informing that a supported service is restricted to a first terminal connected to the BS, in response to the detecting the backhaul network loss;
- receiving, from a second terminal, a second message to request a network entry;
- determining whether the BS operates in a state of a partial backhaul network loss or in a state of a full backhaul network loss;
- in response to determining that the BS operates in the state of the partial backhaul network loss:
- determining whether an elapsed time from the partial backhaul network loss is less or greater than a predetermined period,
- if the elapsed time is less than the predetermined period, transmitting, to the second terminal, a third message including information of available quality of service (QoS) over a unicast downlink channel, and receiving, from the second terminal, a fourth message to continue the network entry, when a type of service requested by the second terminal is supported by the available QoS indicated in the second message, and
- if the elapsed time is greater than the predetermined period, transmitting a fifth message informing that the network entry is prohibited, and transmitting an instruction to perform a handover to one of neighbor BSs;
- and
- in response to determining that the BS operates in the state of the full backhaul network loss:
- transmitting the fifth message informing that the network entry is prohibited,
- transmitting a sixth message including information of neighbor BSs;
- and
- transmitting an instruction to perform a handover to one of neighbor BSs.

A base station (BS) in a wireless access system, the BS comprising:
- a transceiver;
- and
- at least one processor coupled to the transceiver and configured to:
- detect a backhaul network loss;
- transmit a first message informing that a supported service is restricted to a first terminal connected to the BS, in response to detecting the backhaul network loss;
- receive, from a terminal, a second message to request a network entry;
- determine whether the BS operates in a backhaul network loss comprising at least one of a state of a partial backhaul network loss or a full backhaul network loss;
- in response to determining that the BS operates in the state of the partial backhaul network loss:
- determine whether an elapsed time from the partial backhaul network loss is less or greater than a predetermined period,
- if the elapsed time is less than the predetermined period, transmit, to a second terminal, a third message including information of available quality of service (QoS) over a unicast downlink channel, and receive, from the second terminal, a fourth message to continue the network entry, when a type of service requested by the second terminal is supported by the available QoS indicated in the second message, and
- if the elapsed time is greater than the predetermined period, transmit a fifth message informing that the network entry is prohibited;
- and
- in response to determining that the BS operates in the state of the full backhaul network loss:
- transmit the fifth message informing that the network entry is prohibited, and
- transmit a sixth message including information of neighbor BSs.
