APPARATUSES AND METHODS FOR ACCESS POINT NAME (APN) BASED CONGESTION CONTROL DURING A PACKET DATA PROTOCOL (PDP) CONTEXT ACTIVATION PROCEDURE
First Claim
1. A mobile communication device, wirelessly connected to a service network with a default Packet Data Protocol (PDP) context active for an Access Point Name (APN), comprising:
- a wireless module performing wireless transmissions and receptions to and from a service network; and
a controller module transmitting a request message for activating a secondary PDP context associated with the APN to the service network via the wireless module, receiving a rejection message indicating no resource available or congestion for the APN and a value of a back-off timer from the service network via the wireless module, and retransmitting the request message to the service network via the wireless module in response to the value of the back-off timer being zero.

Abstract
A mobile communication device wirelessly connected to a service network with a default Packet Data Protocol (PDP) context active for an Access Point Name (APN) is provided. In the mobile communication device, a wireless module performs wireless transmissions and receptions to and from a service network, and a controller module transmits a request message for activating a secondary PDP context associated with the APN to the service network via the wireless module. Also, the controller module receives a rejection message indicating no resource available or congestion for the APN and a value of a back-off timer from the service network via the wireless module, and retransmits the request message to the service network via the wireless module in response to the value of the back-off timer being zero.

7. A mobile communication device, comprising:
-
a wireless module performing wireless transmissions and receptions to and from a service network; and a controller module transmitting a first request message for activating a default or secondary PDP context associated with an APN to the service network via the wireless module, starting a back-off timer with a value in response to receiving a rejection message corresponding to the first request message from the service network via the wireless module, receiving a second request message for activating a default or secondary PDP context associated with the APN from the service network via the wireless module when the back-off timer is running, and transmitting a response message corresponding to the second request message to the service network via the wireless module. - View Dependent Claims (8, 9, 10, 11, 12, 13, 17, 18, 19, 20)
