EFFICIENT MODIFICATION OF PACKET FILTERS IN A WIRELESS COMMUNICATION NETWORK

摘要

Techniques for modifying packet filters in a wireless communication network are described. In one scheme, packet filters may be performed with multiple operations, if needed. The operation(s) to be performed and the order of performing the operation(s) may be dependent on the number of existing packet filters to be replaced (N) and the number of new packet filters (M). If N = M, then N packet filters in a traffic filter template may be replaced with a single operation. If N > M, then M packet filters in the traffic filter template may be replaced first, and N - M packet filters may be deleted from the traffic filter template next. If N < M, then N - M new packet filters may be added to the traffic filter template first, and N packet filters in the traffic filter template may be replaced next. In another scheme, packet filters are modified with a single operation using dummy packet filters, if needed.
