Abstract: Wireless mobile communication (WMC) devices located in near proximity of each other may be enabled to form a mesh (ad hoc wireless) network. WMC devices may form and/or tear down intra-mesh connection with other WMC devices in the same mesh network. WMC devices may utilize information related to other WMC devices in the mesh network in determining formation and tearing down of intra-mesh connections. This information may comprise relative speeds, locations, and directions of movement of the WMC devices forming/tearing intra-mesh connections. Other information including data bandwidth and/or power consumption may be utilized in such determination. This information may also comprise available services advertised by WMC devices in the mesh network.

Abstract: Methods and systems for auto coexistence priority selection for a SCO link are disclosed. Aspects of one method may include a first Bluetooth device communicating with a collocated WLAN device via a coexistence method. The first Bluetooth device, prior to executing a non-SCO task, which may comprise tasks that do not involve SCO packet transfer, may communicate low priority via the coexistence method if a Bluetooth SCO link is present between the first Bluetooth device and a second Bluetooth device, and if a current task being handled by the first Bluetooth device is a high priority task. If a SCO link is not present between the first and second Bluetooth devices, and if the current non-SCO task is a high priority task, the first Bluetooth device may communicate high priority via the coexistence method prior to executing the non-SCO task.
