Network node and a method of a network node of controlling data packet delivery to a mobile terminal in case of data rate throttling after having reached a data download cap
The present invention relates to a network node ( 14, 18, 21 ) and a method of a network node of controlling data delivery to a mobile terminal ( 11, 12, 13 ) in case of data rate throttling after having reached a data download cap. The method comprises the steps of acquiring (S 101 ) the data to be delivered to the mobile terminal, receiving (S 102 ) an indication that a data download cap for the mobile terminal has been reached, and buffering (S 103 ) the acquired data. The method further comprises the step of delivering (S 104 ) the buffered data to the mobile terminal in bursts.
1. A method by a network node of controlling data to be delivered to a mobile terminal, the method comprising:
receiving an indication that a data download cap has been reached in a current download quota period, for a subscription associated with the mobile terminal; and
responsive to receiving the indication, throttling further data downloads to the mobile terminal during a remaining portion of the current quota period, based on:
buffering data received for delivery to the mobile terminal;
delivering the buffered data to the mobile terminal in bursts; and
controlling the period between the bursts in order to control transition by the mobile terminal into a lower-power state of operation between the bursts.
2. The method according to claim 1 , further comprising:
synchronizing, in case the data pertains to separate communication sessions, the bursts such that the bursts of a first of the separate communication sessions at least partially overlap with the bursts of at least a second of the separate communication sessions.
3. The method according to claim 1 , wherein the step of delivering the buffered data to the mobile terminal in bursts comprises accumulating data received for the mobile terminal in the buffer to form bursts of a desired length, and, to control the period between bursts, concatenating at least two buffered data subsets to form a burst to be delivered to the mobile terminal.
4. A network node for controlling data to be delivered to a mobile terminal, the network node comprising:
memory storing a computer program comprising program instructions; and
a processing circuit configured to execute the program instructions, whereby the processing circuit is configured to:
receive an indication that a data download cap has been reached in a current quota period, for a subscription associated with the mobile terminal; and
responsive to receiving the indication, throttle further data downloads to the mobile terminal during a remaining portion of the current quota period, based on being configured to:
buffer data received for delivery to the mobile terminal;
deliver the buffered data to the mobile terminal in bursts; and
control the period between the bursts in order to control transition by the mobile terminal into a lower-power state of operation between the bursts.
5. The network node according to claim 4 , the processing circuit further being configured to:
synchronize, in case the data pertains to separate communication sessions, the bursts such that the bursts of a first of the separate communication sessions at least partially overlap with the bursts of at least a second of the separate communication sessions.
6. The network node according to claim 4 , the processing circuit further being configured to accumulate the data received the mobile terminal in the buffer to form bursts of a desired length, and, to control the period between bursts, concatenating at least two buffered data subsets to form a burst to be delivered to the mobile terminal.
7. The network node according to claim 4 , said network node being one of: a radio base station (RBS), a base transceiver station (BTS), a NodeB, an eNodeB, a radio network controller (RNC), a base station controller (BSC), a Hypertext Transfer Protocol (HTTP) server, or a proxy server.
8. A non-transitory computer readable medium storing a computer program comprising computer program instructions that, when executed by a processor of a network node, configure the network node to control data to be delivered to a mobile terminal, said computer program comprising program instructions configuring the network node to:
receive an indication that a data download cap has been reached in a current download quota period, for a subscription associated with the mobile terminal; and
responsive to receiving the indication, throttle further data downloads to the mobile terminal during a remaining portion of the current quota period, based on:
buffering data received for delivery to the mobile terminal;
delivering the buffered data to the mobile terminal in bursts; and
controlling the period between the bursts in order to control transition by the mobile terminal into a lower-power state of operation between the bursts.
