First Claim
Patent Images
1. A method of controlling power saving modes of a plurality of terminals joining in a group communication by a base station, the method comprising:
- establishing a group call connection with the plurality of terminals; and
establishing a same power saving mode pattern for the plurality of terminals;
receiving a request message for establishing a power saving mode pattern that is different from the same power saving mode pattern, from a predetermined terminal of the plurality of terminals in which the same power saving mode pattern is established; and
transmitting a response message including information on the different power saving mode pattern to the predetermined terminal, wherein the different power saving mode pattern is applied to the predetermined terminal while the same power saving mode pattern is applied to terminals except the predetermined terminal among the plurality of terminals.

9. A method of controlling a power saving mode by a terminal joining in a group communication, the method comprising:
-
establishing a group call connection with a base station; establishing a same power saving mode pattern as other terminals joining in the group communication; and entering a power saving mode according to the power saving mode pattern; when the same power saving mode pattern as the other terminals is established in the terminal, transmitting a request message for establishing a power saving mode pattern that is different from the same power saving mode pattern, to the base station; and receiving a response message including information on the different power saving mode pattern from the base station, wherein the terminal operates with the different power saving mode pattern in the power saving mode while the other terminals operate with the same power saving mode pattern. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
