Coordination architecture for wireless communication devices using multiple protocols
First Claim
1. A data collision rectification device for use in a wireless communication network wherein data transmissions using frequency-overlapping protocols comprising a first protocol and a second protocol operate to exchange information between a plurality of data transfer nodes, the device comprising:
- a coordination module which determines first and second transmission priorities associated with a first data transmission using the first protocol and a second data transmission using the second protocol, respectively; and
determines a first current quality of service of the first transmission and a second current quality of service of the second transmission; and
a synchronization module which moderates the first transmission in response to determining that (1) the first transmission priority is higher than the second transmission priority, (2) the second current quality of service is not within an acceptable quality of service range for transmissions using the second protocol, and (3) the first current quality of service is within an acceptable quality of service range for transmissions using the first protocol.

Abstract
A system and methods for coordinating transmissions in a wireless network wherein a plurality of frequency-overlapping protocols are used to exchange information between devices. In this system, a coordination point device integrates a monitoring functionality to identify impending data collisions between the frequency-overlapping protocols. The coordination point device further identifies quality of service parameters to determine if the protocols are operating within desirable ranges. Moderation one or more of the protocols is then performed to avoid data collisions arising from overlapping transmissions between the protocols while maintaining data throughput within acceptable ranges.

12. A method of moderating transmission of data in a communication network, wherein a first device transmits a first transmission using a first protocol and a second device transmits a second transmission using a second protocol, the first and second protocols being associated with respective first and second priorities, wherein the first priority is higher than the second priority, the method comprising:
-
determining first and second quality of services ranges associated with respective first and second protocols; monitoring a first current quality of service level of the first transmission and a second current quality of service level of the second transmission, wherein the first and second current quality of service levels are continuously updated during transmission of the first and second transmissions; in response to detecting a collision between the first and second transmissions, moderating one of the first and second transmissions in the following manner; moderating the second transmission in response to determining that the second current quality of service level is within the second quality of service range; moderating the first transmission in response to determining that (1) the second current quality of service level is not within the second quality of service range and (2) the first current quality of service level is within the first quality of service range; and moderating the first transmission in response to determining that (1) the second current quality of service level is not within the second quality of service range and (2) the first current quality of service level is not within the second quality of service level.
