## Abstract

An approach is provided for receiving and transmitting data over a wireless network, while minimizing power consumption. A determination is made, as part of a discontinuous communication mechanism defining an on-period for permitting transmission of data over a network, whether a resource allocation has been made to a user equipment for communicating over the network. If the resource allocation has been made, generating a keep-awake message to instruct the user equipment to extend the on-period.

## Claims

### Claim 1

A method comprising:
determining, as part of a discontinuous communication mechanism defining an on-period for permitting transmission of data over a network, whether a resource allocation has been made to a user equipment for communicating over the network; and
generating, if the resource allocation has been made, a keep-awake message to instruct the user equipment to extend the on-period.

### Claim 2 (depends on 1)

A method according to claim 1, further comprising:
extending the on-period by one transmission time interval at a time based on value of the keep-awake message.

### Claim 3 (depends on 2)

A method according to claim 2, wherein the resource allocation is made during a last transmission time interval of the on-period.

### Claim 4 (depends on 1)

A method according to claim 1, further comprising:
enabling use of the keep-awake message on a cell-by-cell basis or on a user equipment basis.

### Claim 5 (depends on 1)

A method according to claim 1, wherein the keep-awake message corresponds to an allocation table associated with the resource allocation.

### Claim 6 (depends on 1)

A method according to claim 1, wherein the keep-awake message is transmitted in form of a single bit within a dedicated control channel.

### Claim 7 (depends on 1)

A method according to claim 1, further comprising:
transmitting the keep-awake message over the network, wherein the network is compliant with a long term evolution (LTE) architecture.

### Claim 8 (depends on 1)

A method according to claim 1, wherein the discontinuous communication mechanism defines a duty cycle parameter specifying duration of the active state per timeout period, and a duty cycle filter parameter specifying a duty time pattern associated with the duty cycle parameter.

### Claim 9 (depends on 8)

A method according to claim 8, wherein the discontinuous communication mechanism further defines a periodicity parameter specifying frequency for listening for the resource allocations, and a starting parameter specifying start in time or phase of the active state.

### Claim 10
