Abstract
There is disclosed a wireless terminal device in which also when IEEE802.16e is used in an access system of the next generation network, an end-to-end QoS is kept, and comfortable communication can be performed. In a wireless access system including the next generation network as a core network, in a terminal for BWA (the wireless terminal device), an SDP generating section generates a session description protocol (SDP) corresponding to an application, an SDP analysis section analyzes the SDP, a packet classifier section distributes an IP packet to each queue of a QoS class, and a DSA-REQ message generating section sets a QoS parameter of a DSA-REQ message to generate the DSA-REQ message, and reports the message to a wireless base station for the BWA.
Claims4
A wireless terminal device connected to a wireless access system including a core network,
- wherein a parameter of a protocol concerning a communication session in the core network includes a priority class of a service of an application which performs the communication and a used port number, and
- the priority class of the service included in the parameter of the protocol concerning the communication session and a QoS level used in QoS control of uplink in the wireless access system are stored as a correspondence table,
- to determine the QoS level of the communication session based on the priority class of the service included in the parameter of the protocol concerning the communication session in accordance with the correspondence table and to associate the determined QoS level with the port number included in the parameter,
- thereby distributing a packet passing through a port having the port number to a transmission queue of the QoS level.
A wireless terminal device connected to a wireless access system including a core network, comprising:
- an application section which performs communication via the wireless access system;
- a parameter generating section which generates a parameter including a priority class of a service of an application to perform the communication and a used port number as a parameter of a protocol concerning a communication session in the core network in accordance with the service in the application section;
- a parameter analysis section which determines a QoS level of the communication session in accordance with a correspondence table to beforehand associate the priority class included in the parameter of the protocol concerning the communication session in the core network with the QoS level used in QoS control of uplink in the wireless access system and which associates the determined QoS level with the port number included in the parameter;
- and
- a packet classifier section which distributes a packet of application data output from the application section to pass through a port having the port number to a transmission queue of the QoS level based on the QoS level and the port number associated by the parameter analysis section.
