A METHOD OF AND APPARATUS FOR ASSIGNING A UNIT IDENTITY

摘要

This invention relates to a method of and apparatus for assigning a unit identity to remote units (101-107) in a communication system (100). A remote unit (101) comprises means for selecting an identity (201) and broadcasting an identity request message. A second remote unit (103) will upon receiving the identity request message investigate whether the identity is already in use by the second remote unit. If so it will either transmit an identity request message or release the identity. The first remote unit (101) comprises means (211) for assigning the unit identity to the first remote unit (101) if no reject messages are received in response to the unit identity request. The invention is applicable to radio communication systems such as TETRA.
