Description

Traffic processing method and device for high quality service {METHOD AND APPARATUS FOR PROCESSING TRAFFIC FOR SERVICE OF HIGH QUALITY}

The present invention relates to a service technique for processing communication traffic, and more particularly, high quality suitable for processing (optimizing) traffic between each service node providing service and various additional services according to the service policy to users and service policy information nodes in the network. It relates to a method and apparatus for processing traffic for a service.

As is well known, users have their own user terminals (for example, mobile phones, smartphones, smart pads, note pads, tablet PCs, etc.) in accordance with the development of wireless Internet communication environments and services and the development of wireless terminals (portable terminals). ) To provide wireless Internet service such as video anytime, anywhere.

That is, users can access the target server through the user terminal owned by them and receive desired Internet services according to the in-network service policy. To this end, a plurality of service equipment (service nodes) between the user terminal and the target server Alternatively, service servers) are configured as an Internet service provider (ISP) network.

At this time, each service equipment in the ISP network recognizes each user or a specific application, and performs traffic management suitable for each traffic. To this end, each service equipment receives a service request (service request packet) received from the user terminal. Whenever it is processed, signaling is performed to obtain user information and service information by interlocking with the service policy server in the network.

Here, the traffic management technology means traffic management such as how to handle traffic of a certain user and how to handle some applications according to subscriber information and service policy information provided by a network.

However, in the conventional method of obtaining subscriber information and service policy information by interworking with the service policy server in the network for each service equipment, interworking with the service policy server increases as service policy information increases, so that call loads of service equipment There is a problem that increases.

The increase in call load in such a service equipment eventually leads to an increase in cost for increasing the performance of the service equipment, and also causes a problem that makes it difficult to obtain real-time information (service policy information).

The user terminal is each management server included in the mobile communication network belonging to the service area
Traffic processing device for high quality service. ◈ Claim 7 was abandoned when payment of the set registration fee was made.◈ The method of claim 5,
The packet adaptation unit,
When the service request packet is an IP packet, the node service information is inserted into an 8-bit type of service field or an option field,
When the service request packet is a TCP packet, the node service information is inserted into a 5-bit reserved field,
When the service request packet is an HTTP protocol packet, inserting the node service information into a user-defined field in the header of the HTTP request message
Traffic processing device for high quality service. As a traffic processing method for high-quality service to process the traffic generated from the user terminal and transmitted to the service node in the ISP network,
When a service request packet of uplink traffic is received from the user terminal, obtaining user information and service policy information,
Generating a dedicated packet for a node service including the obtained user information and service policy information;
In order to selectively apply the node service for each user, a process of multicasting or broadcasting the generated dedicated packet for the node service to each service node side,
The multicast or broadcast dedicated packets for the node service to the respective service node side are used for the execution of the node service at each service node and then discarded after the traffic processing method for high quality service. A user information acquisition unit that acquires user information from a user information management node when a service request packet of uplink traffic is received from a user terminal;
A policy information acquisition unit for acquiring service policy information from a service information management node when the service request packet is received;
A packet generator configured to generate a dedicated packet for node service including the obtained user information and service policy information;
To selectively apply the node service for each user, a packet transmission unit for multicasting or broadcasting the generated dedicated packet for the node service to each service node side,
The multicast or broadcast dedicated packets for the node service to the respective service node side are used for the execution of the node service at each service node and then discarded after the traffic processing device for high quality service. delete delete delete delete delete
