SYSTEM AND METHOD FOR IMPROVING PDP CONTEXT ACTIVATION LATENCY

摘要

A radio network controller (RNC) receives a request to activate a packet data protocol (PDP) context for a wireless device operating in a forward access channel state. The RNC sends the request to activate PDP context to a core network node (CN). The RNC receives a request to assign a radio access bearer from the CN. The RNC sends a response to the request to assign a radio access bearer to the CN and initiates a timer. If the CN accepts the request to activate the PDP context prior to timer expiry, the RNC stops the timer and sends the wireless device the accept message followed by a request to reconfigure a radio bearer. Otherwise, if the timer expires, the RNC sends the wireless device the request to reconfigure the radio bearer followed by the accept message.

主权项

1. 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 not been received from the core network node before the expiration of the timer, send the wireless device a request to reconfigure the radio bearer, the request to reconfigure the radio bearer sent to the wireless device via a base station.
