Abstract  Abstract

Methods and apparatus for establishing communications between devices e.g. mobile communications devices in an ad hoc network with differing capabilities are described. A device which is capable of supporting multiple protocols in addition to a protocol used to communicate device capability information forms communications links with first and second devices which do not have the ability to form communications links directly between one another e.g. because of they do not support the same protocols. Once the links are established the first and second devices can communicate via the third communications device. In some embodiments each of the first second and third devices support a first communications protocol which is suitable for communicating device capability information but is unsuitable for exchanging user data. The ability to discover other devices and there capabilities facilitates the creation of an ad hoc network.
