Failure Handling Data Traffic Channels for VoIP Control Channel Decoding

The patent applies preliminary action by pre-configuring multiple ordered data traffic channels (first, second, third channels) and their corresponding ordering patterns before control channel reception failure occurs. When failure is detected, the mobile station immediately switches to blind detection on the pre-configured failure handling data traffic channel according to the failure handling ordering pattern, eliminating the need for temporary control resource allocation and reducing network overhead while maintaining reliable resource allocation.

The patent segments the resource allocation mechanism into two independent paths: (1) normal control channel-based allocation for users with good reception, and (2) blind detection on pre-configured failure handling data traffic channels for users with reception failure. This segmentation allows multiple users to share control channel resources efficiently while ensuring that users experiencing fading or shadowing can still reliably receive resource allocations through the alternative blind detection path.

The patent creates a copy of the resource allocation mechanism specifically for failure handling scenarios. Instead of increasing control resources, it establishes parallel failure handling data traffic channels with predetermined ordering patterns that mirror the structure of normal data traffic channels. This copying approach allows reliable resource allocation during failures without consuming additional control resources, preserving maximum resources for voice traffic while providing a redundant allocation path for unreliable users.
