Terminal device, infrastructure equipment, wireless telecommunications network, methods and integrated circuitry

Integrated circuitry for infrastructure equipment, the integrated circuitry comprising:

• transceiver circuitry;
• and
• control circuitry configured to control the transceiver circuitry to:
• exchange data with a terminal device of a wireless telecommunications network using both of a first communications service and a second communications service simultaneously, the first communications service associated with a first quality of service (QOS) for exchanging data and the second communications service associated with a second QOS for exchanging data;
• establish a first radio connection state of a first set of radio connection states with the terminal device, each radio connection state of the first set of radio connection states being associated with the first communications service and the first QOS;
• and
• establish a second radio connection state of a second set of radio connection states with the terminal device, each radio connection state of the second set of radio connection states being associated with the second communications service and the second QOS, wherein
• the first radio connection state is established independently of the second radio connection state,
• one or more of the radio connection states in the first set of radio connection states is associated with a first set of discontinuous reception (DRX) parameters in accordance with the first QOS,
• one or more of the radio connection states in the second set of radio connection states is associated with a second set of DRX parameters in accordance with the second QOS, and
• the control circuitry is further configured to control the transceiver circuitry to use one of the first and second sets of DRX parameters associated with a shortest DRX cycle duration.
