Abstract
A method, apparatus, and computer program for controlling device-to-device connections and associated quality-of-service parameters are presented. The quality-of-service parameters of an end-to-end connection through a plurality of different radio access networks are aligned in connection with changing a communication mode to a direct device-to-device connection.
Claims20
A method, comprising:
- receiving, in an apparatus controlling device-to-device connections for a plurality of radio access net-works, a message indicating establishment of an end-to-end connection between a first terminal device of a first radio access network and a second terminal device of a second radio access network different from the first radio access network, wherein the end-to-end connection is as-signed with a first set of quality-of-service parameters in the first radio access network and a second set of quality-of-service parameters in the second radio access network;
- detecting an event triggering establishment of a direct device-to-device wireless connection between the first terminal device and the second terminal device, wherein the direct device-to-device connection contains no intermediate radio access network between the first terminal device and the second terminal device;
- deriving common quality-of-service parameters for said terminal devices for use in the direct device-to-device connection;
- and
- causing transmission of a message comprising information on the derived common quality-of-service parameters for said terminal devices.
2 more elements
A method comprising:
- establishing, in an apparatus applicable to a first terminal device of a radio access network, a signaling connection with the radio access network as part of establishment of an end-to-end connection with a second terminal device through the radio access network;
- determining quality-of-service parameters for the end-to-end connection;
- receiving a command to change a communication mode of the end-to-end connection to a direct device-to-device connection with the second terminal device, wherein the direct device-to-device connection contains no intermediate radio access network between the first terminal device and the second terminal device;
- receiving new quality-of-service parameters for the device-to-device connection that are assigned as common quality-of-service parameters to the first terminal device and the second terminal device for use in for use in the device-to-device connection;
- and
- configuring the device-to-device connection with the newly received quality-of-service parameters.
3 more elements
An apparatus comprising:
- at least one processor;
- and
- at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- control device-to-device connections for a plurality of radio access networks;
- receive a message indicating establishment of an end-to-end connection between a first terminal device of a first radio access network and a second terminal device of a second radio access network different from the first radio access network, wherein the end-to-end connection is assigned with a first set of quality-of-service parameters in the first radio access network and a second set of quality-of-service parameters in the second radio access network;
- detect an event triggering establishment of a direct device-to-device wireless connection between the first terminal device and the second terminal device, wherein the direct device-to-device connection contains no intermediate radio access network between the first terminal device and the second terminal device;
- derive common quality-of-service parameters for said terminal devices for use in the direct device-to-device connection;
- and
- cause transmission of a message comprising information on the derived common quality-of-service parameters for said terminal devices.
6 more elements
An apparatus comprising:
- at least one processor;
- and
- at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- operate a first terminal device of a radio access network;
- establish a signaling connection with the radio access network as a part of establishment of an end-to-end connection with a second terminal device through the radio access network;
- determine quality-of-service parameters for the end-to-end connection;
- receive a command to change a communication mode of the end-to-end connection to a direct device-to-device connection with the second terminal device, wherein the direct device-to-device connection contains no intermediate radio access network between the first terminal device and the second terminal device;
- receive new quality-of-service parameters for the device-to-device connection that are assigned as common quality-of-service parameters to the first terminal device and the second terminal device for use in the device-to-device connection;
- and configure the device-to-device connection with the newly received quality-of-service parameters.
