Embodiment Construction

[0028] I. Operating environment

[0029] Figure 1 is a diagram of an environment in which the present invention may be employed. Specifically, FIG. 1 shows a short-range wireless communication network 100 with multiple wireless communication devices. These devices include a coordinator device 104 and a number of slave devices (DEVs) 102 . Thus, network 100 may be an ad hoc network, such as an IEEE 802.15.3 piconet or a Bluetooth network.

[0030] In network 100 , each DEV 102 may communicate with coordinator device 104 over a corresponding link 120 . For example, FIG. 1 shows that DEV 102a communicates with coordinator device 104 via link 102a, DEV 102b communicates with coordinator device 104 via link 120b, DEV 102c communicates with coordinator device 104 via link 120c, and DEV 102d communicates via link 120c. Way 120d communicates with coordinator device 104 .

[0031] When considering communications between DEVs 102 , each link 120 is referred to herein as an indirect ...

Abstract

A device participates in a wireless communications network having a coordinator device that is responsible for allocating resources in the wireless communications network. Further, the device establishes a peer-to-peer connection with a remote device in the wireless communications network. This peer-to-peer connection is based on a reservation of resources from the coordinator device, wherein the reservation has one or more timing parameters. Upon detecting a disappearance of the coordinator device from the wireless communications network, communications with the remote device continues according to the one or more timing parameters of the peer-to-peer connection.

Description

[0001] This international application is based upon and claims priority from US Application Serial No. 11 / 169,765, filed June 30, 2005, entitled "Recovery Techniques for Wireless Communications Networks," which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to wireless communications. More specifically, the present invention relates to recovery techniques in wireless communication networks. Background technique [0003] Short-range wireless communication networks generally include devices with a communication range of less than 100 meters. These networks are often connected with other networks in order to provide long-distance communications. For example, short-range networks may interface with cellular networks, wired telecommunications networks, and the Internet. [0004] Terminals in short-range wireless networks often work in an ad hoc (ad hoc) manner. That is, they dynamically create and terminate connectio...
