| 摘要 |
This invention concerns a method of providing a VolP connection through wireless communication links of a packet-based wireless communication system, and a corresponding base station and terminal. The wireless communication links comprise an uplink transmission path (2uc, 2us) from the terminal to the base station, and a downlink transmission path (2dc, 2ds) from the base station to the terminal. Each of the uplink and downlink transmission paths (2uc, 2us, 2dc, 2ds) have a control channel (2uc, 2dc) and at least one data channel (2us, 2ds). Control messages (20d, 21d, 220u, 221u, 230d, 250u, 260u) are generated for scheduling network resources and for suspending and/or re-issuing a persistent grant of network resources allocated to the VolP connection. |
