Wake up procedure for a base station in a communications network
First Claim
1. An apparatus comprising:
- at least one processor;
memory storing a program of instructions;
wherein the memory storing the program of instructions is configured to, with the at least one processor, cause the apparatus to at least;
cause a transmitter of a mobile communication device to transmit an access request message for waking up an apparatus of a communications network in order to achieve access to the communications network, determine successful access to the communications network based on the message, andcause the transmitter to transmit an acknowledgment message for acknowledging the successful access, wherein the acknowledgement message is linked to the access request message such that the access request message can be identified based on the acknowledgement message.

Abstract
A mobile apparatus transmits a message for waking up an apparatus of a communications network in order to achieve access to the communications network. An apparatus of the communications network receives the message, determines whether the apparatus is in a standby mode in which the transmitter is deactivated, and shifts to a wake up mode, in which the transmitter is kept deactivated, for at most an apparatus-specific offset time in response to receipt of the message in case the apparatus is in the standby mode. The apparatus detects whether an acknowledgment message acknowledging that a successful access to the communications network has been achieved based on the message is received in the wake up mode of the apparatus, and the apparatus shifts to an active mode in which the transmitter is activated and provides access to the communications network for the mobile apparatus based on the message using the transmitter in case no acknowledgment message has been received in the wake up mode when the apparatus-specific offset time elapses. Otherwise, the apparatus shifts to the standby mode when the acknowledgement message is received in the wake up mode. The acknowledgment message may be received from the mobile apparatus or from an apparatus of the communications network.

1. An apparatus comprising:
-
at least one processor; memory storing a program of instructions; wherein the memory storing the program of instructions is configured to, with the at least one processor, cause the apparatus to at least; cause a transmitter of a mobile communication device to transmit an access request message for waking up an apparatus of a communications network in order to achieve access to the communications network, determine successful access to the communications network based on the message, and cause the transmitter to transmit an acknowledgment message for acknowledging the successful access, wherein the acknowledgement message is linked to the access request message such that the access request message can be identified based on the acknowledgement message. - View Dependent Claims (2)

3. An apparatus of a communications network, the apparatus comprising:
-
a transmitter; a receiver configured to receive, from a mobile apparatus, a message for waking up the apparatus in order to achieve access to the communications network; and a processor configured to determine whether the apparatus is in a standby mode in which the transmitter is deactivated, shift the apparatus to a wake up mode, in which the transmitter is kept deactivated, for at most an apparatus-specific offset time in response to receipt of the message in case the apparatus is in the standby mode, detect whether an acknowledgment message acknowledging that a successful access to the communications network has been achieved based on the message is received in the wake up mode of the apparatus, shift the apparatus to an active mode in which the transmitter is activated and provide access to the communications network for the mobile apparatus based on the message using the transmitter in, case no acknowledgment message has been received in the wake up mode when the apparatus-specific offset time elapses, and shift the apparatus to the standby mode when the acknowledgement message is received in the wake up mode of the apparatus. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)
where Δ
t is the apparatus-specific offset time, tmin is a minimum offset time and tmax is a maximum offset time, wherein the apparatus comprises an interface configured to receive the minimum offset time and the maximum offset time from the communications network.

9. The apparatus of claim 3, wherein the processor is configured to derive the apparatus-specific offset time from a cell identity of the apparatus and/or determine the apparatus-specific offset time based on a time of deactivation of the transmitter.
-
10. The apparatus of claim 3, comprising an interface, wherein when the processor determines that the apparatus is in the active mode when the message is received, the processor is configured to provide access to the communications network for the mobile apparatus based on the message and cause the interface to send the acknowledgment message acknowledging that the successful access to the communications network has been achieved based on the message to apparatuses of the communications network in case the apparatus has provided access to the communications network for the mobile apparatus based on the message.

11. A method comprising:
-
transmitting an access request message for waking up an apparatus of a communications network in order to achieve access to the communications network; determining successful access to the communications network based on the access request message; and transmitting an acknowledgment message for acknowledging the successful access, wherein the acknowledgement message is linked to the access request message such that the access request message can be identified based on the acknowledgement message. - View Dependent Claims (12, 13, 14, 24, 25, 26)

15. A method for an apparatus of a communications network, the method comprising:
-
receiving, from a mobile apparatus, a message for waking up the apparatus in order to achieve access to the communications network; determining whether the apparatus is in a standby mode in which a transmitter is deactivated; shifting the apparatus to a wake up mode, in which the transmitter is kept deactivated, for at most an apparatus-specific offset time in response to receipt of the message in case the apparatus is in the standby mode; detecting whether an acknowledgment message acknowledging that a successful access to the communications network has been achieved based on the message is received in the wake up mode of the apparatus; shifting the apparatus to an active mode in which the transmitter is activated and providing access to the communications network for the mobile apparatus based on the message using the transmitter in case no acknowledgment message has been received in the wake up mode when the apparatus-specific offset time elapses; and shifting the apparatus to the standby mode when the acknowledgement message is received in the wake up mode of the apparatus. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
