Summary:Methods and apparatus for mitigating data server time-outs in e.g., a hybrid wireless network. In one exemplary embodiment, a client device operating in a hybrid network environment utilizes its knowledge about tune-away periods so as to minimally affect data network operation. For example, during periods of data downlink activity, the client device induces some delay in the acknowledgement packets sent back towards the network prior to entering into a tune away period. These delayed acknowledgement packets result in an increased retransmission time out period value thereby reducing the probability of encountering a data server time-out. Alternative embodiments are also discussed which preoccupy the network apparatus during these tune away periods so as to also mitigate time-outs during these periods. These mitigation algorithms are useful in both downlink and uplink data transmissions. Apparatus for implementing these methodologies are also disclosed.
