Method of Managing Packet Transmission for Wireless System

1 . A method of managing packet transmission for a first wireless system, wherein the first wireless system coexists with at least one second wireless system, the method comprising:

receiving a first type of packet of the first wireless system;

determining whether the step of receiving the first type of packet is interfered by a second type of packet of one of the at least one second wireless system; and

modifying a priority of the first type of packet when the first type of packet is interfered.

2 . The method of claim 1 , further comprising:

retaining the priority of the first type of packet when the first type of packet is not interfered.

3 . The method of claim 1 , wherein when the priority of the first type of packet is lower than a priority of the second type of packet, the step of modifying the priority of the first type of packet when the first type of packet is interfered comprises:

increasing the priority of the first type of packet to be higher than the priority of the second type of packet when the first type of packet is interfered; and

discarding the second type of packet.

4 . The method of claim 3 , further comprising:

retaining the priority of the first type of packet to be lower than the priority of the second type of packet when the first type of packet is not interfered; and

discarding the first type of packet.

5 . The method of claim 1 , further comprising:

applying a time division multiplexing to deal with packet transmission of the first wireless system and the at least one second wireless system.

6 . The method of claim 5 , further comprising:

changing a time sharing schedule of the time division multiplexing within a specific period when the first type of packet is interfered.

7 . The method of claim 5 , wherein the step of determining whether the first type of packet is interfered by the second type of packet of one of the at least one second wireless system comprises:

determining whether the first type of packet has a length longer than a time period allocated for the first wireless system in the time division multiplexing when the first type of packet is interfered by the second type of packet.

8 . The method of claim 1 , wherein the step of determining whether the first type of packet is interfered by the second type of packet of one of the at least one second wireless system comprises:

determining whether the first type of packet comes from a specific network when the first type of packet is interfered by the second type of packet.

9 . The method of claim 1 , wherein the step of determining whether the first type of packet is interfered by the second type of packet of one of the at least one second wireless system comprises:

determining whether the first type of packet is within a specific frequency band when the first type of packet is interfered by the second type of packet.

10 . The method of claim 1 , wherein the step of determining whether the first type of packet is interfered by the second type of packet of one of the at least one second wireless system comprises:

determining whether the first type of packet has a specific profile when the first type of packet is interfered by the second type of packet.

11 . The method of claim 1 , wherein the step of determining whether the first type of packet is interfered by the second type of packet of one of the at least one second wireless system comprises:

determining whether the first type of packet is transmitted via circuit switching or a packet switching when the first type of packet is interfered by the second type of packet.

12 . The method of claim 1 , wherein the step of determining whether the first type of packet is interfered by the second type of packet of one of the at least one second wireless system comprises:

determining whether the first type of packet is a beacon packet, a broadcast packet or a multicast packet when the first type of packet is interfered by the second type of packet.

13 . The method of claim 1 , wherein whether the first type of packet is interfered by the second type of packet is measured as a score corresponding to the first type of packet, wherein the score is determined according to a reference matrix having a plurality of check items wherein each check item has a weight for calculating the score.

14 . The method of claim 1 , wherein the step of modifying the priority of the first type of packet when the first type of packet is interfered comprises:

increasing the priority of the first type of packet when a specific number of previous first type of packets are discarded.

15 . The method of claim 1 , wherein the step of modifying the priority of the first type of packet when the first type of packet is interfered comprises:

decreasing the priority of the first type of packet when a specific number of previous first type of packets are received successfully.

16 . The method of claim 1 , wherein the step of modifying the priority of the first type of packet when the first type of packet is interfered is performed in a hardware manner.

17 . The method of claim 16 , wherein hardware of the first wireless system modifies the priority of the first type of packet when the first type of packet is interfered.

18 . The method of claim 16 , wherein hardware of the first wireless system modifies following first type of packets when the first type of packet is interfered.

19 . The method of claim 1 , wherein the step of modifying the priority of the first type of packet when the first type of packet is interfered is performed in a software manner.

20 . The method of claim 19 , wherein the first wireless system sends an interrupt signal to a processing unit to modify a priority of following first type of packets when the first type of packet is interfered.
