Method and apparatus for updating multicast and broadcast service system information in a wireless access system |
摘要 |
The present description relates to a method for updating E-MBS-related system information in an idle mode state, comprising the following steps: receiving, from a base station, a first system configuration descriptor (SCD) message containing an E-MBS-related parameter; receiving, from the base station, a first message containing an indicator for indicating whether or not to change the E-MBS-related parameter; and, if the indicator indicates that the E-MBS-related parameter is to be changed, shifting from the idle mode state to a connected mode state. |

1. A method of updating enhanced multicast and broadcast service (E-MBS) related system information in an idle mode, the method comprising:
receiving a first system configuration descriptor (SCD) message including an E-MBS related parameter from a base station; receiving a first message including an indicator indicating whether the E-MBS related parameter is changed from the base station; and performing a wake-up operation in the idle mode when the indicator indicates that the E-MBS related parameter is changed, wherein the indicator indicates whether an E-MBS related parameter included in an SCD message first transmitted after the first message is transmitted is changed, wherein the indicator is an SCD update indicator represented by a bitmap, wherein the first message further includes an SCD transmission time offset field indicating a time that a second SCD message including the changed E-MBS related parameter is transmitted, and wherein a size of the SCD transmission time offset field is determined according to a value of an E-MBS scheduling interval (EMI). |
