Abstract

Communication systems may benefit from connection setup improvements. For example, fifth generation communication systems may benefit from low latency service connection setup for 5G network terminal in new service areas. A method can include receiving an indication of preference for services from a 5G network terminal. The method can also include determining that the indication indicates a preference for low latency services. The method can further include determining whether the low latency services are offered in a tracking area of the 5G network terminal. The method can additionally include communicating with the 5G network terminal regarding the availability of the low latency services.

Claims

1. A method, comprising:

receiving an indication of preference for services from a user equipment;

determining that the indication indicates a preference for low latency services;

determining whether the low latency services are offered in a tracking area of the user equipment; and

communicating with the user equipment regarding the availability of the low latency services.

2. The method of claim 1, wherein the communication comprises providing an indication that low latency services are available.

3. The method of claim 2, wherein the indication that low latency services are available is provided with a tracking area update accept message.

4. The method of claim 1, wherein the indication of the preference is provided in an initial user equipment message.

5. The method of claim 1, further comprising:

retaining network access stratum signaling connection when it is determined that the indication indicates the preference for low latency services and that the low latency services are offered.

6. A method, comprising:

determining that a user equipment has a changed mobile specific area identifier or determining that a user equipment has a changed service area identifier; and

reporting a mobility event based on the changed mobile specific area identifier or changed service area identifier,

wherein the mobility event is configured to trigger conditional network initiated service connection setup.

7. A method, comprising:

receiving a report a changed mobile specific area identifier or changed service area identifier, for a user equipment;

determining whether a new service area, corresponding to the changed mobile specific area identifier or changed service area identifier, offers the service to the user equipment; and

triggering network initiated service connection setup upon determining that the service is offered in the new service area.

8. The method of claim 7, wherein the triggering comprises sending a device triggering message via a mobile control plane to a corresponding application in the user equipment.

9. The method of claim 7, wherein the triggering comprises sending a broadcast message to announce the service to the user equipment in the new service area, wherein the broadcast message is configured to trigger a corresponding application in the user equipment.

10. The method of claim 7, wherein the triggering comprises setting up user plane resources or user plane state for a service connection and notifying the user equipment that the service connection is set up.

11. The method of claim 10, further comprising:

receiving a negative acknowledgment from the user equipment regarding the service connection; and

triggering deactivation of the service connection based on the negative acknowledgment.

12. A method, comprising:

receiving a tracking area update accept message with a service availability indicator;

and

determining whether to initiate service connection setup based on the service availability indicator; and

initiating establishment of service connection setup when it is so determined.

13. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to

receive an indication of preference for services from a user equipment;

determine that the indication indicates a preference for low latency services;

determine whether the low latency services are offered in a tracking area of the user equipment; and

communicate with the user equipment regarding the availability of the low latency services.

14. The apparatus of claim 13, wherein the communication comprises providing an indication that low latency services are available.

15. The apparatus of claim 14, wherein the indication that low latency services are available is provided with a tracking area update accept message.

16. The apparatus of claim 13, wherein the indication of the preference is provided in an initial user equipment message.

17. The apparatus of claim 13, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to retain network access stratum signaling connection when it is determined that the indication indicates the preference for low latency services and that the low latency services are offered.

18. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to

determine that a user equipment has a changed mobile specific area identifier or determining that a user equipment has a changed service area identifier; and

report a mobility event based on the changed mobile specific area identifier or changed service area identifier,

wherein the mobility event is configured to trigger conditional network initiated service connection setup.

19. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to receive a report a changed mobile specific area identifier or changed service area identifier, for a user equipment;

determine whether a new service area, corresponding to the changed mobile specific area identifier or changed service area identifier, offers the service to the user equipment; and

trigger network initiated service connection setup upon determining that the service is offered in the new service area.

20. The apparatus of claim 19, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to trigger by sending a device triggering message via a mobile control plane to a corresponding application in the user equipment.

21. The apparatus of claim 19, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to trigger by sending a broadcast message to announce the service to the user equipment in the new service area, wherein the broadcast message is configured to trigger a corresponding application in the user equipment.

22. The apparatus of claim 19, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to trigger by setting up user plane resources or user plane state for a service connection and notifying the user equipment that the service connection is set up.

23. The apparatus of claim 22, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:

receive a negative acknowledgment from the user equipment regarding the service connection; and

trigger deactivation of the service connection based on the negative acknowledgment.

24. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to
