Abstract

Various methods are described for determining a communications window for served nodes and internal applications in order to optimize power consumption. One example method may comprise determining a communications window for a plurality of served nodes. The method of this embodiment may also include causing the communications window to be signaled to the plurality served nodes. The method of this embodiment may also include causing a communications interface to be activated during the communications window in an instance in which at least one packet is received for at least one served node of the plurality of served nodes.

Claims

1-48. -48. (canceled)

49. A method comprising:

determining a communications window for a plurality of served nodes; and

causing the communications window to be signaled to the plurality of served nodes,

wherein a router advertisement is configured to be signaled to the plurality of served nodes, and

wherein the router advertisement comprises an indication of an interval timing of the communications window, a timing of a next communications window and a duration of the communications window.

50. A method according to claim 49, further comprising:

causing a communications window for one or more internal applications to be altered based on the communications window signaled to the plurality of served nodes.

51. A method according to claim 49, further comprising:

determining a served node of the plurality of served nodes that has transmitted a highest frequency of transmissions in a predetermined period; and

causing the communications window to be adjusted based on a communications interval used by the served node that has transmitted the highest frequency of transmissions in the predetermined period.

52. A method according to claim 49, further comprising:

determining a served node of the plurality of served nodes that is not configured to receive the signal comprising the communications window; and

causing the communications window to be adjusted to a communications interval used by the served node that is not configured to receive the signal comprising the communications window.

53. A method according to claim 49, wherein the router advertisement comprises a IPv6 router advertisement.

54. A method according claim 49, further comprising:

causing the router advertisement to be signaled at the beginning of a communications window.

55. A method according to claim 49, wherein the communications window includes a predetermined delay from a start time of the communications window for each of the plurality of served nodes.

56. A method according to claim 49, further comprising:

causing a communications interface to be activated during the communications window in an instance in which at least one packet is received for at least one served node of the plurality of served nodes.

57. A method according to claim 49, further comprising:

causing the communications window to be signaled via at least one of a layer 2 protocol, an wireless application protocol, hypertext transfer protocol, dynamic host configuration protocol version 4, dynamic host configuration protocol version 6 or a constrained application protocol.

58. A method according to claim 49, wherein the communications interface is a cellular radio interface.

59. An apparatus comprising:

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least;

determine a communications window for a plurality of served nodes; and

cause the communications window to be signaled to the plurality of served nodes,

wherein a router advertisement is configured to be signaled to the plurality of served nodes, and

wherein the router advertisement comprises an indication of an interval timing of the communications window, a timing of a next communications window and a duration of the communications window.

60. An apparatus according to claim 59, wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to:

cause a communications window for one or more internal applications to be altered based on the communications window signaled to the plurality of served nodes.

61. An apparatus according to claim 59, wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to:

determine a served node of the plurality of served nodes that has transmitted a highest frequency of transmissions in a predetermined period; and

cause the communications window to be adjusted based on a communications interval used by the served node that has transmitted the highest frequency of transmissions in the predetermined period.

62. An apparatus according to claim 59, wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to:

determine a served node of the plurality of served nodes that is not configured to understand the signal comprising the communications window; and

cause the communications window to be adjusted to a communications interval used by the served node that is not configured to receive the signal comprising the communications window.

63. An apparatus according to claim 59, wherein the router advertisement comprises a IPv6 router advertisement.

64. An apparatus according to claim 59, wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to:

cause the router advertisement to be signaled at the beginning of a communications window.

65. An apparatus according to claim 59, wherein the communications window includes a predetermined delay from a start time of the communications window for each of the plurality of served nodes.

66. An apparatus according to claim 59, wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to:

cause a communications interface to be activated during the communications window in an instance in which at least one packet is received for at least one served node of the plurality of served nodes.

67. An apparatus according to claim 59, wherein the at least one memory including the computer program code is further configured to, with the at least one processor, cause the apparatus to:

cause the communications window to be signaled via at least one of a layer 2 protocol, an wireless application protocol, hypertext transfer protocol, dynamic host configuration protocol version 4, dynamic host configuration protocol version 6, or a constrained application protocol.

68. An apparatus according to claim 59, wherein the communications interface is a cellular radio interface.
