Problems solved by technology

[0003] If an attempt is made to implement QoS control in the wireless section in such a mobile communication system, then, for example, when downlink (downlink) data reaches the MAC in IPv4 layer, the IP header has been removed, and therefore no control using the TOS field of the IP header can be performed

Embodiment Construction

[0047] First, before describing the communication system of the embodiment, reference will be made to figure 1 A descriptive view to describe the frame configuration of OFDMA used in this communication system.

[0048] figure 1 The frame configuration of OFDMA in the case where the time slots used in this communication system are, for example, four (S1 to S4) is shown, where the vertical axis is the frequency axis and the horizontal axis is the time axis.

[0049] exist figure 1 , each of the downlink cycle and the uplink cycle is divided into 28 frequency bands with respect to the frequency axis. The subchannels in the first frequency band are called control subchannels and are used for a control channel (CCH). The first frequency band may be the highest frequency band or the lowest frequency band. Furthermore, the control subchannel commands which subchannel of the time slot is used for each of the frequency bands.

[0050] exist figure 1 In the example shown, the base s...

Abstract

One base station and one terminal are connected via one radio link to realize multiservice. A communication system comprises a communication control means (2-1) for performing communication on the basis of an OFDMA system having a traffic channel composed of first sub-channels including information indicating a sub-channel whose usage is permitted or not permitted and second sub-channels for storing data on the multiservice corresponding to the first sub-channels, allocating each of the first sub-channels to the plural services, and connecting the one base station and the one terminal via the one radio link to perform multiservice communication.

Description

technical field [0001] The present invention relates to a communication system, a base station, a terminal and a communication method used in the communication system. Background technique [0002] In the OSI reference model, the QoS control of the wireless part in the mobile communication system (such as digital portable telephone system and PHS system) is realized through the digital link layer (MAC layer). Here, QoS (Quality of Service) consists in a function of setting priority (service priority) for each communication in the network, thereby guaranteeing transmission quality. [0003] If an attempt is made to implement QoS control in the wireless section in such a mobile communication system, then, for example, when the downlink (downlink) data reaches the MAC layer in IPv4, the IP header has been removed, and thus the exploit cannot be performed. Control of the TOS field of the IP header. [0004] Therefore, negotiation of service priority is performed during connect...
