Abstract
Methods, wireless device (500) and network node (502) which can be used when resuming a communication session after a period of inactivity of the wireless device (500). The wireless device (500) sends to a network node (502) a resuming request comprising an indication of at least one preferred network slice out of a set of network slices that was used in the communication session before said period of inactivity. Thereby, the network node (502) is able to determine the preferred network slice(s) based on the indication in the resuming request.
Claims10
A method performed by a wireless device, the method comprising:
- registering to use one or more network slices for a communication session on a network, each of the one or more network slices having a corresponding at least one of a Data Radio Bearer (DRB) identifier and an index number;
- entering an inactive state for a communication session with the network;
- after a period of inactivity, determining to resume the communication session with the network;
- upon determining to resume the communication with the network:
- determining at least one registered network slice that the wireless device prefers to use, the determination of the at least one registered network slice that the wireless device prefers to use being based on one of data and a signaling message to be transmitted, and the determined at least one registered network slice comprising at least one of the Data Radio Bearer (DRB) identifier associated and an index number of each network slice that the wireless device prefers to use;
- and
- sending, to a network node, a request to resume the communication session with the network, the request comprising the determined ones of the registered network slices that the wireless device prefers to use upon resuming the communication session after the period of inactivity;
- and
- receiving, from the network node, an indication that the communication session is being resumed and that the wireless device is to use one of the registered network slices that were indicated as preferred.
A wireless device comprising:
- communication circuitry configured to communicate with a wireless network;
- and
- processing circuitry operably coupled to the communication circuitry, the processing circuitry and the communication circuitry being configured to:
- register to use one or more network slices for a communication session on a network, each of the one or more network slices having a corresponding at least one of a Data Radio Bearer (DRB) identifier and an index number;
- enter an inactive state for a communication session with the network;
- after a period of inactivity, determine to resume the communication session with the network;
- upon determining to resume the communication with the network:
- determine at least one registered network slice that the wireless device prefers to use, the determination of the at least one registered network slice that the wireless device prefers to use being based on one of data and a signaling message to be transmitted, and the determined at least one registered network slice comprising at least one of the Data Radio Bearer (DRB) identifier associated and an index number of each network slice that the wireless device prefers to use;
- and
- send, to a network node, a request to resume the communication session with the network, the request comprising the determined ones of the registered network slices that the wireless device prefers to use upon resuming the communication session after the period of inactivity;
- and
- receive, from the network node, an indication that the communication session is being resumed and that the wireless device is to use one of the registered network slices that were indicated as preferred.
