The present invention relates to a mobile communication system, and more particularly, to an apparatus and a method for providing quality of service information in an IP Multimedia Subsystem (IMS) network.
With the rapid development of communication technology, it has reached the stage of providing a high-speed data service capable of providing a general voice service as well as a multimedia service such as an e-mail or a still image as well as a moving image by a portable terminal.
The so-called 3rd generation (3G) mobile communication systems supporting both general voice service and packet service include synchronous CDMA 20001x systems and asynchronous Universal Mobile Telecommunication Systems (UMTS). The third generation mobile communication system as described above provides a multimedia service to a portable terminal through interworking with an IMS network and other networks.
The portable terminal capable of interworking with the IMS network and other networks uses a voice data service in a circuit switch network such as a UMTS (Universal Mobile Telecommunication System) (UMTS) and a Global System for Mobile (GSM). In a WLAN environment, a multi-mode portable terminal that can use VoIP services.
The IMS was introduced as a release 5 standard in the 3rd Generation Partnership Project (3GPP), which is a standard research organization of the 3rd generation mobile communication system.
In other words, the IMS is a network for effectively supporting the demand for wireless data and multimedia services in the mobile communication network while supporting the existing voice service as it is.
The process of requesting the service quality information by the portable terminal in the IMS network as described above is the same as the method described below.
The calling mobile terminal to use the IMS service negotiates the quality of service information request with the receiving mobile terminal using a session initiation protocol message.
In this case, the portable terminals can transmit a quality of service requirement using a session description protocol (SDP).
The P-CSCF, which is the contact point of the IMS service, generates a service information using the session description protocol exchanged between the originating portable terminal and the receiving portable terminal and generates a policy / charging function (PCRF). Rule functions).
The policy / charge determination function that receives the service information uses the received service information, the subscriber profile information obtained from the subscriber profile storage unit, and the information included in the request of the GGSN to determine a QoS decision and a charge decision ( Create PCC rules information including charging rules).
Here, the PCC rules information includes information including a type of service authorized to the subscriber provided by the subscriber profile storage unit, service quality information permitted to the subscriber, billing information of the subscriber, and subscriber category, and an application function AF. Information including the IP address, media type and bandwidth of the mobile terminal, application information of the application function, recording information of the application function, and the like, and the IP address of the mobile terminal requested from the GGSN, and subscriber authentication information. It can be generated using the included information.
Thereafter, the policy / billing determination function provides the generated PCC rules information to the GGSN.
Here, the PCC rules may be transmitted using a CC-Answer (CCA) message that includes information including a quality of service class and a maximum bandwidth value for an uplink downlink, and the quality of service class is conversational. (Conversational) service class, streaming service class, interactive service class, and background service class.
The GGSN receiving the PCC rules generates resource allocation and charging information for bearer traffic using the received PCC rules.
However, the above-mentioned mobile communication network allocates resources for session creation using service class information and maximum bandwidth information determined by service information, but does not provide service quality information for a service to be used by a user. .
SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus and method for providing service quality information according to a type of service when creating a session in an IMS network.
Another object of the present invention is to provide an apparatus and method for providing service quality information using service ID information when creating a session in an IMS network.
According to a first aspect of the present invention for achieving the above objects, an apparatus for providing a quality of service in an IP Multimedia Subsystem (IMS) includes a type of service to be used in a calling mobile terminal. Type of service to be used by the proxy call session function control unit for generating service information and providing it as a policy / billing determining function and the calling mobile terminal included in the service information provided from the proxy call session function control unit. It generates a PCC rules including the quality of service (QoS decision) information and charging rules (Charging rules) information, and comprises a policy / billing decision function for providing the generated PCC rules to the packet gateway device .
According to a second aspect of the present invention for achieving the above object, a method for providing a quality of service in an IP Multimedia Subsystem (IMS) is a service for notifying the type of service to be used by the calling portable terminal; Generating service information including ID, and generating PCC rules including quality of service decision information and charging rule information using the generated service information and subscriber profile. and providing the rules to the packet gateway device.
Hereinafter, the operating principle of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, when it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.
