Abstract

Claims (25)

1. A method to determine a Quality of Service, QoS, parameter, the method comprising:

receiving, at a base station, and from a time sensitive networks application function (TSN-AF) entity, a QoS parameter request to establish a current session, whereby the QoS parameter request comprises a descriptor for the current session and an indication that the current session is a probing session between the base station and a mobile device for purpose of probing the QoS parameter to be applied in a protocol data unit (PDU) session to be established in the future between the base station and the mobile device for purpose of transmitting and/or receiving data from/to a data network in accordance with the determined QoS parameter;

determining, at the base station, the QoS parameter related to the current probing session; and

transmitting, by the base station, the determined QoS parameter to the TSN-AF entity,

wherein the base station is prevented from reserving resources for use by the mobile device during the current probing session, and

wherein the base station will reserve resources for use by the mobile station during the future PDU session for the transmitting and/receiving of data from/to the data network.

2. The method according to claim 1 , whereby the QoS parameter request comprises several messages.

3. The method according to claim 1 , whereby the base station does not reserve resources as an action relative to the QoS parameter request.

4. The method according to claim 1 , whereby the QoS parameter request comprises a QoS parameter determination context, whereby the QoS parameter determination context comprises both a parameter determination constraint and an indication of a type of QoS parameter to be determined within the parameter determination constraint.

5. The method according to claim 4 , whereby the QoS parameter determination constraint comprises one or more of a maximum bit rate, priority, or packet error rate, and whereby the type of QoS parameter to be determined within the parameter determination constraint comprises delay information.

6. The method according to claim 1 , whereby the QoS parameter request comprises a probing flag, the probing flag indicating considering the current probing session as replacing current active PDU sessions at the base station, or the probing flag indicating considering the current probing session in addition to other current active PDU sessions at the base station.

7. The method according to claim 1 , whereby the determining, at the base station, of the QoS parameter related to the current probing session comprises building, by the base station, a resource reservation plan for the current probing session.

8. The method according to claim 1 , wherein, while the base station is determining the QoS parameter related to the current probing session, the base station is prevented from releasing any current active PDU sessions and from establishing an additional PDU session at the base station.

9. The method according to claim 1 , whereby the QoS parameter request is also to establish one or more additional current probing sessions between the base station and one or more other mobile stations, the descriptor further relating to the one or more additional current probing sessions and the indication further indicating that the one or more additional current probing sessions are being requested.

10. The method according to claim 9 , whereby the determining, at the base station, of the QoS parameter related to the current probing session comprises:

determining, at the base station, the QoS parameter related to the one or more additional current probing sessions; and

building, by the base station, a resource reservation plan for the current probing session and for the one or more additional current probing sessions.

11. A method to determine a Quality of Service, QoS, parameter, the method comprising:

transmitting, by a time sensitive networks application function (TSN-AF) entity, and to a plurality of base stations, QoS parameter requests to establish a current session, whereby each QoS parameter request comprises a descriptor for the current session and an indication that the current session is a probing session between the base station and a mobile device for purpose of probing the QoS parameter to be applied in a protocol data unit (PDU) session to be established in the future between the base station and the mobile device for purpose of transmitting and/or receiving data from/to a data network in accordance with the determined QoS parameter;

receiving, at the TSN-AF entity, and from each base station of the plurality of base stations, base station specific QoS parameters related to the current probing session; and

compiling, by the TSN-AF entity, the received base station specific QoS parameters into a QoS profile,

wherein the base station is prevented from reserving resources for use by the mobile device during the current probing session, and

wherein the base station will reserve resources for use by the mobile station during the future PDU session for the transmitting and/receiving of data from/to the data network.

12. A non-transitory computer-readable storage medium comprising instructions which, when executed by a processor of a computing device, cause the processor to carry out the method of claim 1 .

13. A device comprising a processor, a memory and a networking module, the processor being configured to operate according to claim 1 .
