Abstract

An approach is provided for an approach to manage a power saving scheme for multicast or broadcast services. A signal is received from a terminal configured to utilize a power-save mechanism. State of a multicast or broadcast group is determined for the terminal based on the signal. The power-save mechanism of the terminal is bypassed if the state is determined to be active to permit transmission of data, which is designated for the multicast or the broadcast group, to the terminal.

Claims

1. A method comprising:

receiving a signal from a terminal configured to utilize a power-save mechanism;

determining state of a multicast or broadcast group for the terminal based on the signal; and

bypassing the power-save mechanism of the terminal if the state is determined to be active to permit transmission of data, which is designated for the multicast or the broadcast group, to the terminal.

2. A method according to claim 1, the method further comprising:

transmitting the data to the terminal over a wireless network.

3. A method according to claim 2, wherein the wireless network is a local area network (LAN) compliant with an Institute of Electrical and Electronic Engineers (IEEE) 802.11 architecture.

4. A method according to claim 2, wherein the terminal is further configured to operate over another wireless network including a cellular network.

5. A method according to claim 1, wherein the terminal is in an inactive state, the method further comprising:

generating a message to specify that the terminal can use the power-save mechanism.

6. An apparatus comprising:

a module configured to receive a signal from a terminal configured to utilize a power-save mechanism, and to determine state of a multicast or broadcast group for the terminal based on the signal,

wherein the module is further configured to bypass the power-save mechanism of the terminal if the state is determined to be active to permit transmission of data, which is designated for the multicast or the broadcast group, to the terminal.

7. An apparatus according to claim 6, the apparatus further comprising:

a transmission module configured to transmit the data to the terminal over a wireless network.

8. An apparatus according to claim 7, wherein the wireless network is a local area network (LAN) compliant with an Institute of Electrical and Electronic Engineers (IEEE) 802.11 architecture.

9. An apparatus according to claim 7, wherein the terminal is further configured to operate over another wireless network including a cellular network.

10. An apparatus according to claim 6, wherein the terminal is in an inactive state, the module is further configured to generate a message to specify that the terminal can use the power-save mechanism.

11. A method comprising:

generating a signal specifying an active state associated with a multicast or broadcast group, the signal being transmitted to an access point; and

avoiding entry into a power-saving mode based on the generated signal or another signal generated by any member of the group specifying an active state for the group.

12. A method according to claim 11, the method further comprising:

receiving data destined for the group from the access point over a wireless network.

13. A method according to claim 12, wherein the wireless network is a local area network (LAN) compliant with an Institute of Electrical and Electronic Engineers (IEEE) 802.11 architecture.

14. A method according to claim 12, further comprising:

generating a message for transmission over another wireless network.

15. A method according to claim 14, wherein the other wireless network includes a cellular network.

16. An apparatus comprising:

a processor configured to generate a signal specifying an active state associated with a multicast or broadcast group, the signal being transmitted to an access point,

wherein entry into a power-saving mode is avoided based on the generated signal or another signal generated by any member of the group specifying an active state for the group.

17. An apparatus according to claim 16, the apparatus further comprising:

a transceiver configured to receive data destined for the group from the access point over a wireless network.

18. An apparatus according to claim 17, wherein the wireless network is a local area network (LAN) compliant with an Institute of Electrical and Electronic Engineers (IEEE) 802.11 architecture.

19. An apparatus according to claim 17, further comprising:

a first transmission module configured to transmit and receive data from the wireless network; and

a second transmission module configured to transmit and receive data from another wireless network.

20. An apparatus according to claim 19, wherein the other wireless network includes a cellular network.
