Infrastructure equipment and methods

6:

• A method of transmitting data to a communications device from an infrastructure equipment forming a base station of a mobile communications network, the method comprising
• receiving a paging request from a mobility management entity of the mobile communications network for transmission to one of the communications devices,
• in response transmitting a first paging message to the communications device to indicate that the communications device is to receive the data via the wireless access interface, and
• if a response to the transmitted first paging message is not received from the communications device within a predetermined time, then
• if the infrastructure is able to use a power boosting mode, transmitting the first paging message with a boosted power, or
• if the infrastructure equipment is not able to use a power boosted mode for transmitting,
• transmitting a second paging message to one or more communications apparatus which can operate as a relay node for the communications device, the second paging message identifying the relay node and the communications device for which the infrastructure equipment is to transmit the data.

7:

• An infrastructure equipment forming a mobility management entity of a mobile communications network, the infrastructure equipment comprising
• a communications interface for connecting the infrastructure equipment to one or more base stations within a tracking area of the mobile communications network, and
• a controller configured in response to receiving an indication that data is to be transmitted to a communications device,
• to transmit via the communications interface a paging request to one or more of the base stations in the tracking area to transmit a first paging message to the communications device indicated in the paging request, and
• if a response to the transmitted first paging message is not received within a predetermined time, then
• to transmit via the communications interface a second paging request to the one or more base stations within the tracking area either to transmit the first paging message with a boosted power, if the base station is able to use a power boosting mode, or
• if the base station is not able to use a power boosted mode for transmitting,
• to transmit via the communications interface a second paging message to one or more communications apparatus which can operate as a relay node for the communications device, the second paging message identifying the relay node and the communications device for which the base station is to transmit the data.

8:

• An infrastructure equipment as claimed in claim 7, wherein the controller in combination with the communications interface are configured
• to transmit a request to each of the one or more base stations within the tracking area for an indication as to whether the base station can transmit using the power boosted mode,
• to receive an indication from the base station as to whether the base station can transmit using the power boosted mode, and if the base station can transmit using the power boosted mode, and if the base station can transmit using the power boosted mode,
• to transmit a request to the base station to transmit the first paging message with the power boosted mode, if a response to the transmitted first paging message is not received within the predetermined time, or if the base station cannot transmit using the power boosted mode,
• to transmit a request to the base station via the communications interface to transmit the second paging message to the one or more communications apparatus which can operate as the relay node for the communications device.

11:

• An infrastructure equipment as claimed in claim 7, comprising a data store, wherein the controller is configured
• to detect if a communications apparatus has acted as a relay node for one or more communications devices, which have transmitted data to a serving base station or received data from the serving base station via the relay node,
• to store in the data store an indication of the one or more communications apparatus which have acted as a relay node, in association with an indication of their serving base station, and
• to identify from the indication from the base station on whether it can use power boosting which communications apparatus which has acted as a relay node for the communications device will be requested to act as the relay node for the communications device, and
• to transmit the second paging message to the communications apparatus to act as the relay node for the communications device to receive the data from the identified serving base station, which is identified by the indication stored in the data store.

14:

• Electronic circuitry for a base station of a mobile communications network for transmitting data to communications devices or receiving data from communications devices, the electronic circuitry comprising
• transmitter circuitry configured to transmit signals representing data to the communications devices via a wireless access interface,
• receiver circuitry configured to receive signals from the communications devices via the wireless access interface, and
• controller circuitry for controlling the transmitter and the receiver
• to receive a paging request from a mobility management entity of the mobile communications network for transmission to one of the communications devices,
• in response to transmit a first paging message to the communications device to indicate that the communications device is to receive the data via the wireless access interface, and
• if a response to the transmitted first paging message is not received within a predetermined time, then
• if the infrastructure is able to use a power boosting mode, to transmit the first paging message with a boosted power, or
• if the infrastructure equipment is not able to use a power boosted mode for transmitting,
• to transmit a second paging message to one or more communications apparatus which can operate as a relay node for the communications device, the second paging message identifying the relay node and the communications device for which the infrastructure equipment is to transmit the data.

15:

• Electronic circuitry for a mobility management entity of a mobile communications network, the electronic circuitry comprising
• communications interface circuitry for connecting the infrastructure equipment to one or more base stations within a tracking area of the mobile communications network, and
• controller circuitry configured in response to receiving an indication that data is to be transmitted to a communications device,
• to transmit via the communications interface a paging request to one or more of the base stations in the tracking area to transmit a first paging message to the communications device indicated in the paging request, and
• if a response to the transmitted first paging message is not received within a predetermined time, then
• to transmit via the communications interface a second paging request to the one or more base stations within the tracking area either to transmit the first paging message with a boosted power, if the base station is able to use a power boosting mode, or
• if the base station is not able to use a power boosted mode for transmitting,
• to transmit via the communications interface a second paging message to one or more communications apparatus which can operate as a relay node for the communications device, the second paging message identifying the relay node and the communications device for which the base station is to transmit the data.
