Abstract

A wireless access system having a subscriber subsystem gateway (20) and a wireless router (30) in communication with the gateway via a two-way radio channel (25) according to a communication protocol. The communication protocol has a medium access control (MAC) layer (602, 603, 604, 605) capable of supporting several different network layer frame types (610-612 and 613-615) and includes a MAC layer header (800) having a frame type indicator (801), so that multiple frames of differing frame types are communicated contiguously over the radio channel separated by MAC layer headers.

Claims

1. A method of operation of a wireless access system comprising:

receiving a first type packet and a second type packet in a network layer, the first type packet being associated with a first logical channel having a first quality of service (QoS) parameter and the second type packet being associated with a second logical channel having a second quality of service (QoS) parameter;

fragmenting the first type packet into first and second fragments in a medium access control (MAC) layer when the second QoS parameter calls for more urgent delivery than the first QoS parameter; and

inserting the second type packet between the first and second 20 fragments in the MAC layer and transmitting the first fragment, the second type packet and the second fragment as a continuous multiplexed stream of data on a physical channel, thereby advancing transmission of the second type packet with respect to the second fragment of the first type packet.

2. The method of claim 2, further comprising providing each of the first fragment, the second type packet and the second fragment with an encapsulation header in the MAC layer, where the encapsulation header includes a packet type indication
