Abstract

Disclosed is a method that includes receiving, when in a radio resource control (RRC) Connected state, a RRC connection release message from a network access node; setting a wait timer in accordance with a wait timer indication that comprises part of the RRC connection release message; and upon an expiration of the wait timer, enabling the initiating of sending an RRC connection request message to the network access node. Also disclosed is a method that includes operating a network access node with mobile node and sending a RRC connection release message to the mobile node. The RRC connection release message comprises a wait timer indication for specifying an amount of time that the mobile node should wait before initiating the sending of a RRC connection request message. Various apparatus and computer programs stored on non-transitory computer-readable medium are disclosed that are configured to execute the methods.

Claims

1. A method comprising:

sending, related to a non-access stratum (NAS) procedure, an RRC connection setup complete message;

receiving, in response to the RRC connection setup complete message, when in a radio resource control (RRC) Connected state in an evolved universal terrestrial radio access network, an RRC connection release message from a network access node;

aborting the non-access stratum (NAS) procedure;

setting a wait timer in accordance with a wait timer indication that comprises part of the RRC connection release message; and

upon an expiration of the wait timer, repeating the non-access stratum (NAS) procedure and enabling the initiation of sending an RRC connection request message to the network access node.

2. The method of claim 1, where the wait timer indication is received in an information element that explicitly defines a duration of a setting for the wait timer.

3. The method of claim 1, where the wait timer indication is received as information that implicitly defines a duration of a setting for the wait timer.

4. A non-transitory computer-readable medium that contains software program instructions, where execution of the software program instructions by at least one data processor results in performance of operations that comprise execution of the method of claim 1.

17. The method of claim 1, wherein the RRC connection setup complete message comprises information indicative of the type of communication of a user equipment.

5. An apparatus comprising:

at least one data processor; and

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

send, related to a non-access stratum (NAS) procedure, an RRC connection setup complete message;

receive, in response to the RRC connection setup complete message, when in a radio resource control (RRC) Connected state in an evolved universal terrestrial radio access network, an RRC connection release message from a network access node;

abort the non-access stratum (NAS) procedure;

set a wait timer of the apparatus in accordance with a wait timer indication that comprises part of the RRC connection release message; and

,

upon an expiration of the wait timer, repeat the non-access stratum (NAS) procedure and enable an initiation of sending an RRC connection request message to the network access node.

6. The apparatus of claim 5, where the wait timer indication is received in an information element that explicitly defines a duration of a setting for the wait timer.

7. The apparatus of claim 5 where the wait timer indication is received as information that implicitly defines a duration of a setting for the wait timer.

8. The apparatus of claim 7, where the information comprises part of a release cause indication, and where the wait timer is set to a predetermined value.

18. The apparatus of claim 5, wherein the RRC connection setup complete message comprises information indicative of the type of communication of a user equipment.

9. A method comprising:

receiving, related to a non-access stratum (NAS) procedure, an RRC connection setup complete message from a user equipment in an evolved universal terrestrial radio access network;

sending, in response to the RRC connection setup complete message, an RRC connection release message to the user equipment,

wherein the RRC connection release message comprises a wait timer indication for specifying an amount of time that the user equipment should wait after aborting the non-access stratum (NAS) procedure for repeating the non-access stratum (NAS) procedure and enabling the initiation of sending an RRC connection request message.

10. The method of claim 9, where the wait timer indication is included in an information element that explicitly defines a duration of the setting for the wait timer.

11. The method of claim 9, where the wait timer indication is sent as information that implicitly defines a duration of the setting for the wait timer.

12. A non-transitory computer-readable medium that contains software program instructions, where execution of the software program instructions by at least one data processor results in performance of operations that comprise execution of the method of claim 9.

19. The method of claim 9, wherein the RRC connection setup complete message comprises information indicative of the type of communication of a user equipment.

13. An apparatus comprising:

at least one data processor; and

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

receive, related to a non-access stratum (NAS) procedure, an RRC connection setup complete message from a user equipment in an evolved universal terrestrial radio access network;

send, in response to the RRC connection setup complete message, an RRC connection release message to the user equipment,

wherein the RRC connection release message comprises a wait timer indication for specifying an amount of time that the user equipment should wait after aborting the non-access stratum (NAS) procedure for repeating the non-access stratum (NAS) procedure and enabling the initiation of sending an RRC connection request message.

14. The apparatus of claim 13, where the wait timer indication is included in an information element that explicitly defines a duration of the setting for the wait timer.

15. The apparatus of claim 13, where the wait timer indication is sent as information that implicitly defines a duration of the setting for the wait timer.

16. The apparatus of claim 13, where the wait timer indication is sent in a release cause indication.

20. The apparatus of claim 13, wherein the RRC connection setup complete message comprises information indicative of the type of communication of a user equipment.
