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 or more content providers;
- classifying the received traffic into at least one or more groups, based on information regarding content providers, included in stored traffic characteristic-related information, and transmitting the classification information to a Packet Data Network Gateway (P-GW);
- determining whether a bearer corresponding to Quality of Service Class Identifier (QCI) information of the classified traffic groups exists;
- and
- transmitting, if a bearer corresponding to QCI information of the classified traffic groups does not exist, a signal for establishing a bearer corresponding to QCI information of the classified traffic groups 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 regarding 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 regarding the traffic group, in response to the bearer establishment signal,
- wherein the QCI information corresponds to a QoS characteristic of the traffic group and is previously determined based on information regarding a content provider of a traffic group.
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 QoS characteristic of the traffic group and is previously determined based on information regarding a content provider of a traffic group.
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 or more bearers;
- and
- allocating wireless resources, based on information regarding weights included in Quality of Service (QoS) characteristics corresponding to the at least one or more bearers.
A service accelerator for performing the transmission of traffic in a mobile communication system comprising:
- an interface unit for transmitting/receiving traffic or information to/from another network device;
- and
- a controller for:
- receiving traffic from at least one or more content providers;
- classifying the received traffic into at least one or more groups, based on information regarding content providers, included in stored traffic characteristic-related information, and transmitting the classification information to a Packet Data Network Gateway (P-GW);
- determining whether a bearer corresponding to Quality of Service Class Identifier (QCI) information of the classified traffic groups exists;
- and transmitting, if a bearer corresponding to QCI information of the classified traffic groups does not exist, a signal for establishing a bearer corresponding to QCI information of the classified traffic groups 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 unit for transmitting/receiving information to/from another network device;
- and
- a controller for:
- receiving, from a service accelerator, a bearer establishment signal corresponding to Quality of Service Class Identifier (QCI) information regarding 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 regarding the traffic group, in response to the bearer establishment signal,
- wherein the QCI information corresponds to a QoS characteristic of the traffic group and is previously determined based on information regarding a content provider of a traffic group.
A Packet Data Network Gateway (P-GW) for performing the transmission of traffic in a mobile communication system comprising:
- an interface unit for transmitting/receiving traffic or information to/from another network device;
- and
- a controller for:
- 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 QoS characteristic of the traffic group and is previously determined based on information regarding a content provider of a traffic group.
A base station for performing the transmission of traffic in a mobile communication system comprising:
- an interface unit for transmitting/receiving traffic or information to/from another network device;
- and
- a controller for:
- receiving, from a Packet Data Network Gateway (P-GW), a traffic group transmitted via at least one or more bearers;
- and allocating wireless resources, based on information regarding weights included in Quality of Service (QoS) characteristics corresponding to the at least one or more bearers.
