REDUCING DATA TRANSFER LATENCY CAUSED BY STATE TRANSITIONS IN MOBILE NETWORKS

WIPO Patent Application WO/2014/027108

A3

Examples of reducing data transfer latency caused by state transitions in mobile networks are disclosed. A first disclosed example method comprises, while operating in a first state having fewer available radio resources than would be available in a second state, setting a traffic volume indicator if a wireless device determines that a radio link control (RLC) buffer occupancy is larger than a traffic volume measurement threshold, and sending the traffic volume indicator to a network in a transmitted message other than a CELL UPDATE message having uplink data transmission as an update cause. A second disclosed example method comprises, while operating in a first state, receiving a message that is to cause a wireless device to transition to a second state having fewer available radio resources than are available in the first state, and rejecting the message if the wireless device has pending uplink data to send to a network.
