Abstract:
1. A method of allocating bandwidth in a wireless communication system which method comprises (i) allocating each user a pre-defined priority ranking level; (ii) allocating each pre-defined priority ranking level a pre-emptive section of the bandwidth wherein, when a first user logs on, said first user uses his allocated pre-emptive section of the bandwidth, and wherein, if that allocated pre-emptive section of the bandwidth is full, the call from said first user uses a part of the bandwidth not being used by any other user, and wherein, if all the bandwidth which has been allocated to users of other priority ranking levels to that of said first user is being used, a call from a user of lower priority than the priority of said first user and which is outside the allocated pre-emptive section of the bandwidth of said lower priority user is terminated and the call from said first user, which is of higher priority, is allocated that part of the bandwidth previously used by said terminated lower priority user and wherein if all the users of a lower priority ranking level than said first user occupy their pre-emptive section of the bandwidth, and a user of a higher priority ranking level than said first user occupies bandwidth outside the allocated pre-emptive section of the bandwidth, the call of said higher priority user is terminated and the bandwidth allocated to the said first user.
