Method and arrangement for polling management

摘要

In a packet-based communication network ( 10 ) polling of connected user equipment is performed according to a first type (T1) and a complementary second type (T2). Upon receiving polling according to type one (T1) a user equipment ( 30 ) is allowed to transmit user data packets (UP) if any are available, otherwise the user equipment ( 30 ) can remain silent. In response to polling according to type two (T2), the user equipment ( 30 ) is required to either transmit an available user data packet (UP) or a dummy data packet (DP).
