CONNECTION IDENTITY ALLOCATION METHOD

摘要

This invention describes a type of connection identity allocation method, for use in Wimax, whereby the network allocates cells connected by an ownership relationship to the same relay station to association-cell-sets, and allocates a connection identity group to the aforementioned relay station, so that terminals may communicate with a cell within the association-cell-set using connection identities in the connection identity group, through the following steps: The network informs the target cell which has an ownership relationship with the relay station to reserve the aforementioned connection identity group, where the aforementioned target cell belongs to the aforementioned cell set; the transfer of relay station ownership occurs, and the original cell releases the connection identity with the terminal; the terminal then uses the reserved connection identity in the connection identity group to communicate with the aforementioned target cell. The use of this invention can avoid signal interchanges during the connection identity reallocation negotiation procedure, simplifies the relay station ownership transfer signal procedure, thus reducing time delays, improving service quality, and reducing line drop rates.
