Method, apparatus and computer program product for preserving a signalling connection
View Patent ↗A method, apparatus, and computer program product are provided for preserving a signaling connection after a network has indicated that the signaling connection can be closed, such as by selection of a no follow on proceed mode during routing area updates or attach procedures. By preserving the signaling connection, subsequent communications between the network and the user equipment can be completed without closing and then subsequently reopening the signaling connection.
1. A method comprising:
receiving a signal connection release mode indication, the signal connection release mode indication being associated with a signaling connection of a mobile terminal;
initiating a timer based on the signal connection release mode indication, wherein upon expiration of the timer, the signaling connection will be closed;
receiving communication prior to expiration of the timer and subsequent to initiating the timer; and
halting the timer in response to receipt of the communication to prevent expiration of the timer and to correspondingly disallow closing of the signaling connection.
2. The method of claim 1 , wherein receiving the signal connection release mode indication includes receiving the signal connection release mode indication, the signal connection mode indication being included in a general packet radio service (GPRS) routing update.

5. The method of claim 1 , wherein receiving the communication includes receiving the communication as a series of data packets.
6. The method of claim 1 , wherein receiving the communication includes receiving communication as a session management/general packet radio service (GPRS) mobility management protocol data unit (SM/GMM PDU).
7. The method of claim 1 further comprising initiating a closing of the signaling connection upon receipt of an entirety of the communication.
8. An apparatus comprising a processor, the processor configured to:
receive a signal connection release mode indication, the signal connection release mode indication being associated with a signaling connection;
initiate a timer based on the signal connection release mode indication, wherein upon expiration of the timer, the signaling connection will be closed;
receive a communication prior to expiration of the timer and subsequent to initiating the timer; and
halt the timer in response to receipt of the communication to prevent expiration of the timer and to correspondingly disallow closing of the signaling connection.
9. The apparatus of claim 8 , wherein the processor configured to receive the signal connection release mode indication includes being configured to receive the signal connection release mode indication, the signal connection mode indication being included in a general packet radio service (GPRS) routing update.
10. The apparatus of claim 8 , wherein the processor configured to receive the signal connection release mode indication includes being configured to receive the signal connection release mode indication, the signal connection mode indication including a follow on proceed bit that indicates a signal connection release mode that is to be implemented.
11. The apparatus of claim 8 , wherein the processor configured to receive the signal connection release mode indication includes being configured to receive the signal connection release mode indication, the signal connection release mode indication being associated with the signaling connection, the signaling connection being a packet switched (PS) signaling connection.
12. The apparatus of claim 8 , wherein the processor configured to receive the communication includes being configured to receive the communication as a series of data packets.
13. The apparatus of claim 8 , wherein the processor configured to receive the communication includes being configured to receive the communication as a session management/general packet radio service (GPRS) mobility management protocol data unit (SM/GMM PDU).
14. The apparatus of claim 8 , wherein the processor is further configured to initiate a closing of the signaling connection upon receipt of an entirety of the communication.
15. The apparatus of claim 8 further comprising a computer-readable storage medium, the computer-readable storage medium configured to store the signal connection release mode indication.
16. A computer program product comprising at least one computer-readable storage medium having executable computer-readable program code instructions stored therein, the computer-readable program code instructions comprising:
first program code instructions configured to receive a signal connection release mode indication, the signal connection release mode indication being associated with a signaling connection;
second program code instructions configured to initiate a timer based on the signal connection release mode indication, wherein upon expiration of the timer, the signaling connection will be closed;
third program code instructions configured to receive a communication while the timer is running and subsequent to initiating the timer; and
fourth program code instructions configured to halt the timer in response to receipt of the communication to prevent expiration of the timer and to correspondingly disallow closing of the signaling connection.
17. The computer program product of claim 16 , wherein the first program code instructions configured to receive the signal connection release mode indication includes being configured to receive the signal connection release mode indication, the signal connection mode indication being included in a general packet radio service (GPRS) routing update.
18. The computer program product of claim 16 , wherein first program code instructions configured to receive the signal connection release mode indication includes being configured to receive the signal connection release mode indication, the signal connection mode indication including a follow on proceed bit that indicates a signal connection release mode that is to be implemented.
19. The computer program product of claim 16 , wherein the first program code instructions configured to receive the signal connection release mode indication includes being configured to receive the signal connection release mode indication, the signal connection release mode indication being associated with the signaling connection, the signaling connection being a packet switched (PS) signaling connection.
20. The computer program product of claim 16 , wherein the first program code instructions configured to receive the communication includes being configured to receive the communication as a series of data packets.
21. The computer program product of claim 16 , wherein the third program code instructions configured to receive the communication includes being configured to receive the communication as a session management/general packet radio service (GPRS) mobility management protocol data unit (SM/GMM PDU).
22. The computer program product of claim 16 , wherein the computer-readable program code instructions further comprise fifth program code instructions configured to initiate a closing of the signaling connection upon receipt of an entirety of the communication.
23. An apparatus comprising:
means for receiving a signal connection release mode indication, the signal connection release mode indication being associated with a signaling connection;
means for initiating a timer based on the signal connection release mode indication, wherein upon expiration of the timer, the signaling connection will be closed;
means for receiving a communication prior to expiration of the timer and subsequent to initiating the timer; and
means for halting the timer in response to receipt of the communication to prevent expiration of the timer and to correspondingly disallow closing of the signaling connection.
