Abstract

Exemplary embodiments including a method including determining a user equipment of a wireless communication network is in an autonomous mobility mode; receiving an indication from the wireless communication network of a data communication available for the user equipment; and based on the indication, establishing a connection between the user equipment and a network node of the wireless communication network. Apparatus, program products, and software to perform the exemplary embodiments are also disclosed.

First claim

What is claimed is:

1. An apparatus, comprising:
one or more processors and one or more memories including a computer program code, wherein the one or more memories and the computer program code are configured with the one or more processors to cause the apparatus to at least:
provide a notification to a core network of a wireless communication network about an autonomous mobility mode of a user equipment of a wireless communication network;
determine that the user equipment of the wireless communication network is in the autonomous mobility mode;
receive an indication from the wireless communication network of a data communication available for the user equipment; and
based on the indication, establish a connection between the user equipment and a network node of the wireless communication network for the data communication,
where the indication from the wireless communication network comprises at least one page directed to a defined paging area associated with multiple cells, and where the defined paging area is a gradually increasing paging area for each successive page of the at least one page.

2. The apparatus according to claim 1 , wherein there is a radio resource control connection between the user equipment and the at least one other network node, and where information for the radio resource control connection is maintained during the autonomous mobility mode, and the establishing comprises reestablishing based on the indication the radio resource control connection between the user equipment and the at least one other network node, and where the establishing enables communicating data with the user equipment.

3. The apparatus according to claim 1 , wherein the one or more memories and the computer program code are configured with the one or more processors to cause the apparatus further to:
provide a forward preparation message to the at least one other network node for notifying about the autonomous mobility mode such that the at least one other network node is enabled to proceed with re-establishment signaling from the user equipment, wherein the forward preparation message comprises context of the user equipment.

4. The apparatus according to claim 1 , where the indication is communicated using control plane signaling.

5. The apparatus according to claim 1 , where the determining is based on a stoppage of a data communication between the user equipment and the apparatus.

6. The apparatus according to claim 1 , where the determining is based on an expiration of a timer associated with the stoppage of the data communication between the user equipment and the apparatus.

7. The apparatus according to claim 1 , where the notification of the autonomous mobility mode of the user equipment is communicated to the core network based on a stoppage of data communication.

8. The apparatus according to claim 1 , where the notification is communicated with at least one of a mobility management entity, a serving gateway via a mobility management entity, and directly to a serving gateway.

9. The apparatus according to claim 1 , where the apparatus comprises a base station of the wireless communication network.

10. The apparatus of claim 1 , wherein the notification to the core network is provided in service request signalling.

11. The apparatus of claim 1 , wherein providing the notification to the core network comprises sending a radio bearer release message to a mobile management entity of the core network, wherein the radio bearer release message comprises the notification that the user equipment is in the autonomous mobility mode and causes the mobile management entity to modify an area for paging.

12. The apparatus of claim 1 , wherein providing the notification to the core network comprises sending an end marker message to a serving gateway of the core network, wherein the end marker message comprises the notification that the user equipment is in the autonomous mobility mode and causes the S1-U context to be released at the serving gateway.

13. The apparatus of claim 1 , wherein the notification is provided to the core network after the user equipment has not been reached in a cell of the apparatus.

14. The apparatus of claim 1 , wherein the notification is provided to the core network substantially upon determining that the user equipment is currently in the autonomous mobility mode.

15. The apparatus of claim 1 , wherein the one or more memories and the computer program code are configured with the one or more processors to further cause the apparatus to:
receive a notification of the autonomous mobility mode from the user equipment in a radio resource connection setup complete message.
