System and method for improving PDP context activation latency

A method for improving packet data protocol (PDP) context activation latency in a radio network controller, comprising:

• receiving a request to activate a PDP context for a wireless device operating in a forward access channel state;
• sending the request to activate the PDP context to a core network node;
• receiving a request to assign a radio access bearer from the core network node;
• sending the request to assign the radio access bearer to the wireless device via the base station;
• receiving a response to the request to assign the radio access bearer from the wireless device via the base station;
• sending the response to the request to assign the radio access bearer to the core network node;
• initiating a timer after sending the response to the request to assign the radio access bearer to the core network node;
• determining whether an accept message is received from the core network node before expiration of the timer, the accept message corresponding to the request to activate the PDP context;
• and
• upon determining that the accept message has not been received from the core network node before the expiration of the timer, sending the wireless device a request to reconfigure a radio bearer, the request to reconfigure the radio bearer sent to the wireless device via a base station.

A radio network controller, comprising:

• one or more processors;
• and
• a non-transitory computer-readable storage medium further including computer-readable instructions that, when executed by the one or more processors, are configured to:
• receive a request to activate a packet data protocol (PDP) context for a wireless device operating in a forward access channel state;
• send the request to activate the PDP context to a core network node;
• receive a request to assign a radio access bearer from the core network node;
• send the request to assign the radio access bearer to the wireless device via the base station;
• receive a response to the request to assign the radio access bearer from the wireless device via the base station;
• send the response to the request to assign the radio access bearer to the core network node;
• initiate a timer after sending the response to the request to assign the radio access bearer to the core network node;
• determine whether an accept message is received from the core network node before expiration of the timer, the accept message corresponding to the request to activate the PDP context;
• upon determining that the accept message has been received from the core network node before the expiration of the timer, stop the timer and send the accept message to the wireless device via a base station;
• and
• send the wireless device a request to reconfigure a radio bearer, the request to reconfigure the radio bearer sent via the base station after sending the accept message.

• and
• sending the wireless device a request to reconfigure a radio bearer, the request to reconfigure the radio bearer sent via the base station after sending the accept message.
