Abstract
The present invention relates to the transmission of traffic in a mobile communication system and, more particularly, to a method and device for transmitting traffic in consideration of a quality of service (QoS) characteristic of the traffic. The purpose of the present invention is to efficiently provide a QoS differentiated according to traffic in consideration of a traffic type and a content provider in a network congestion situation of the mobile communication system.
Claims20
A traffic transmission method of a service accelerator in a mobile communication system comprising:
- receiving traffic from at least one content provider;
- classifying the received traffic into at least one traffic group based on content provider information associated with the at least one content provider that transmitted the traffic;
- determining whether a bearer corresponding to Quality of Service Class Identifier (QCI) information of the classified at least one traffic group exists;
- and
- transmitting, if the bearer corresponding to the QCI information of the classified at least one traffic group does not exist, a signal for establishing the bearer corresponding to QCI information of the at least one classified traffic group to a Policy and Charging Rules Function (PCRF).
A traffic transmission supporting method of a Policy and Charging Rules Function (PCRF) in a mobile communication system comprising:
- receiving, from a service accelerator, a bearer establishment signal corresponding to Quality of Service Class Identifier (QCI) information a traffic group to be transmitted to a Packet Data Network Gateway (P-GW);
- and
- transmitting, to the P-GW, a bearer establishment command corresponding to QCI information on the traffic group, in response to the bearer establishment signal,
- wherein the QCI information corresponds to a Quality of Service (QoS) characteristic of the traffic group and is determined based on information on a content provider of the traffic group which is classified based on content provider information associated with the at least one content provider that transmitted the traffic.
A traffic transmission method of a Packet Data Network Gateway (P-GW) in a mobile communication system comprising:
- receiving, from a Policy and Charging Rules Function (PCRF), a bearer establishment command corresponding to Quality of Service Class Identifier (QCI) information of a traffic group to be received from a service accelerator;
- and
- establishing a bearer corresponding to the QCI information or modifying an existing bearer to correspond to the received QCI information, in response to the bearer establishment command,
- wherein the QCI information corresponds to a Quality of Service (QoS) characteristic of the traffic group and is determined based on information on a content provider of the traffic group which is classified based on content provider information associated with the at least one content provider that transmitted the traffic.
A traffic transmission method of a base station in a mobile communication system comprising:
- receiving, from a Packet Data Network Gateway (P-GW), a traffic group transmitted via at least one bearer corresponding to Quality of Service Class Identifier (QCI) information;
- and
- allocating wireless resources, based on information on weights included in Quality of Service (QoS) characteristics corresponding to the at least one bearer,
- wherein the QCI information corresponds to a QoS characteristic of the traffic group and is determined based on information on a content provider of the traffic group which is classified based on content provider information associated with the at least one content provider that transmitted the traffic.
A service accelerator for performing the transmission of traffic in a mobile communication system comprising:
- an interface;
- a controller configured to control the interface to receive traffic from at least one content provider, classify the received traffic into at least one traffic group based on content provider information associated with the at least one content provider that transmitted the traffic, determine whether a bearer corresponding to Quality of Service Class Identifier (QCI) information of the classified at least one traffic group exists, and control the interface to transmit, if the bearer corresponding to the QCI information of the classified at least one traffic group does not exist, a signal for establishing the bearer corresponding to QCI information of the classified at least one traffic group to a Policy and Charging Rules Function (PCRF).
A Policy and Charging Rules Function (PCRF) for supporting the transmission of traffic in a mobile communication system comprising:
- an interface:
- and
- a controller configured to control the interface to receive, from a service accelerator, a bearer establishment signal corresponding to Quality of Service Class Identifier (QCI) information on a traffic group to be transmitted to a Packet Data Network Gateway (P-GW), and transmit, to the P-GW, a bearer establishment command corresponding to QCI information on the traffic group, in response to the bearer establishment signal,
- wherein the QCI information corresponds to a Quality of Service (QoS) characteristic of the traffic group and is determined based on information on a content provider of the traffic group which is classified based on content provider information associated with the at least one content provider that transmitted the traffic.
A Packet Data Network Gateway (P-GW) for performing the transmission of traffic in a mobile communication system comprising:
- an interface;
- and
- a controller configured to control the interface to receive, from a Policy and Charging Rules Function (PCRF), a bearer establishment command corresponding to Quality of Service Class Identifier (QCI) information of a traffic group to be received from a service accelerator;
- and establish a bearer corresponding to the QCI information or modifying an existing bearer to correspond to the received QCI information, in response to the bearer establishment command,
- wherein the QCI information corresponds to a Quality of Service (QoS) characteristic of the traffic group and is determined based on information on a content provider of the traffic group which is classified based on content provider information associated with at least one content provider that transmitted the traffic.
A base station for performing the transmission of traffic in a mobile communication system comprising:
- an interface;
- and
- a controller configured to control the interface to receive, from a Packet Data Network Gateway (P-GW), a traffic group transmitted via at least one bearer corresponding to Quality of Service Class Identifier (CQI) information;
- and allocate wireless resources, based on information on weights included in Quality of Service (QoS) characteristics corresponding to the at least one bearer,
- wherein the QCI information corresponds to a QoS characteristic of the traffic group and is determined based on information on a content provider of the traffic group which is classified based on content provider information associated with the at least one content provider that transmitted the traffic.
