Communications system, infrastructure equipment, communications device and methods

An infrastructure equipment forming part of a wireless communications network comprising:

• transmitter circuitry configured to transmit signals to a communications device via a wireless access interface provided by the wireless communications network,
• receiver circuitry configured to receive signals from the communications device via the wireless access interface, and
• controller circuitry configured:
• to receive an indication that the communications device is preparing to transmit or receive data with one or more pre-authorized quality of service, PAQ, flows to or from the infrastructure equipment, at least one of the PAQ flows currently being inactive,
• wherein the infrastructure equipment is a first infrastructure equipment which is a target of a handover from a second infrastructure equipment the second infrastructure equipment currently serving the communication device,
• wherein the communications device is configured to receive a handover command from the second infrastructure equipment, the handover command comprising a backoff timer, wherein the setup of a new radio bearer for one or more of the PAQ flows is deferred until the backoff timer has elapsed.

A communications device, comprising:

• transmitter circuitry configured to transmit signals to an infrastructure equipment forming part of a wireless communications network via a wireless access interface provided by the wireless communications network,
• receiver circuitry configured to receive signals from the infrastructure equipment via the wireless access interface, and
• controller circuitry configured:
• to transmit or receive signals via the wireless access interface to or from a peer terminal in the wireless communications network with one or more pre-authorized quality of service, PAQ, flows, at least one of the PAQ flows currently being inactive, and
• to transmit an indication to the wireless communications network that the communications device is preparing to transmit or receive data with the PAQ flows to or from the infrastructure equipment,
• wherein the infrastructure equipment is a first infrastructure equipment which is a target of a handover from a second infrastructure equipment, the second infrastructure equipment currently serving the communication device,
• wherein the communications device is configured to receive a handover command from the second infrastructure equipment, the handover command comprising a backoff timer, wherein the setup of a new radio bearer for one or more of the PAQ flows is deferred until the backoff timer has elapsed.
