Abstract
A flow control method includes a step of receiving individual data of each session from a network in an individual trunk apparatus and transmitting the received individual data as a transmission side common channel data to a common buffer, a step of temporarily storing data of plural sessions received from the individual trunk apparatus all at once and monitoring the congestion of the common channel according to the common buffer use amount, and upon detection of a congestion level, a step of stopping or limiting transmission of individual data of a session corresponding to a QoS class having a low priority from the individual trunk apparatus to the common buffer.
Claims16
A method of flow control for a common channel in a base station transmitting-receiving control system for wireless communication for multiple access including said common channel for multiplex transmission, said method comprising the steps of:
- receiving individual data for each session from a network at an individual trunk apparatus and transmitting the received individual data to a common buffer as transmission side common channel data;
- temporarily storing data of a plurality of the sessions received from said individual trunk apparatus in said common buffer all together and monitoring a congestion condition of said common channel from an amount of used portion of said common buffer;
- and
- halting or restricting transmitting individual data of a session corresponding to a QoS class having a priority that is low to said common buffer from said individual trunk apparatus when said congestion condition is detected.
A method of flow control for a common channel in a base station transmitting-receiving control system for wireless communication for multiple access including said common channel for multiplex transmission, said method comprising the steps of:
- receiving individual data for each session from a network at an individual trunk apparatus and transmitting the received individual data to a common buffer as transmission side common channel data;
- temporarily storing data of a plurality of the sessions received from said individual trunk apparatus in said common buffer all together and monitoring a congestion condition of said common channel from an amount of used portion of said common buffer;
- and
- when said congestion condition is detected in a condition that a vacant channel exists in individual channels on said multiple access, directly assigning the individual data of the session corresponding to a QoS having a priority that is high to said vacant channel at a transmission side from the individual trunk apparatus to transmit it.
A flow control system for a common channel in a base station transmitting-receiving control system for wireless communication for multiple access including said common channel for multiplex transmission, said system comprising:
- an individual trunk apparatus for transmitting individual data for each session received from a network as transmission side common channel data;
- and
- a common buffer apparatus, having a common buffer temporarily storing data of a plurality of the sessions received from said individual trunk apparatus all together, for monitoring a congestion condition of the channel from an amount of used portion of said common buffer,
- wherein from said individual trunk apparatus to said common buffer apparatus, transmission of the individual data is halted or restricted for a session corresponding to a QoS class having a priority that is low when a congestion condition is detected in said common buffer apparatus.
A flow control system for a common channel in a base station transmitting-receiving control system for wireless communication for multiple access including said common channel for multiplex transmission, said system comprising:
- an individual trunk apparatus for transmitting individual data for each session received from a network as transmission side common channel data;
- and
- a common buffer apparatus, having a common buffer temporarily storing data of a plurality of the sessions received from said individual trunk apparatus in said common buffer all together, for monitoring a congestion condition of said common channel from an amount of used portion of said common buffer;
- wherein when said congestion condition is detected, at said common buffer apparatus, in a condition that a vacant channel exists in individual channels on said multiple access, said individual trunk apparatus directly assigns the individual data of the session corresponding to a QoS having a priority that is high to said vacant channel at a transmission side to transmit it.
