On the other hand, as shown in Figure 1, the network information notification service system according to the present invention may further include a call exchange device (210).

When the subscription request message is received from the terminal device 00, the call exchange device 210 recognizes a network information notification service device (eg 300) corresponding to the corresponding destination based on the subscription request message and then provides a network information notification service. The device 300 provides the subscription request message.

The call exchange apparatus 210 is an exchange apparatus that sets up a call session according to a call attempt request received from the terminal apparatus 100 so that the terminal apparatus 100 can use a desired communication service. It is preferable to correspond to the Call Session Control Function (CSCF) that manages call processing in. In particular, the call exchange apparatus 210 may correspond to P (Proxy) -CSCF corresponding to the first access point where the terminal apparatus 100 accesses the communication network 200 to use a communication service.

Accordingly, when the call exchange device 210 receives a message (eg, a register message, a part-time message, a subscription request message, etc.) from the terminal device 10, the call exchange device 210 checks the received message and receives a subscription request message (eg, SUBSCRIBE).

A subscription request message (eg SUBSCRIBE message) may be provided.

Of course, if the received message is determined to be a general call attempt message (eg, a register message), the call exchanger 210 may provide the received register message to the I-CSCE 220 according to a general call processing method. Network processing will be performed according to the corresponding register message.

The terminal device 100 is a terminal using a communication service using a call session set up through the call exchange device 100 by requesting a call attempt for a communication service, and a terminal capable of requesting subscription of an information notification service. Would be possible.

The terminal device 100 generates a subscription request message (eg, a SUBSCRIBE message) for requesting the network information notification service device (eg, 300) to subscribe to a predetermined information notification service, and generates a call of the communication network 200. It is provided to the exchange device (210).

In this case, the terminal device 100 preferably generates a subscription request message including event information (eg, an event header) indicating the type of information notification service to be subscribed. For example, the terminal device 100 requests to subscribe to the information notification service 1 for receiving network use related information including usable communication port information corresponding to the communication network 200 and location registration retry timing information. Generate a subscription request message (eg, a SUBSCRIBE message) that includes event information (eg, an Event header), and receive network usage-related information including only available communication port information corresponding to the communication network 200. For example, a subscription request message (eg, a SUBSCRIBE message) including event information (eg, an event header) requesting to join the notification service 2 may be generated.

The terminal device 100 may correspond to a subscriber of the information notification service provided by the present invention.

The network information notification service device 300 is located in the communication network 200 and collects / manages resource state information on resources of the communication network 200, and transmits the call information from the terminal device 100 to the call exchange device 210. When the subscription request message is received, the terminal device 100 is registered in response to the information notification service based on the subscription request message.

The network information notification service device 300, based on a predefined information notification policy, when the information notification time for the information notification service is reached, the network information notification service terminal based on the resource state information, the predetermined network usage related information. To the device 100.

The network information notification service device 300 may correspond to the Notifier of the information notification service provided by the present invention.

Hereinafter, a detailed configuration of the network information notification service device 300 according to the present invention will be described with reference to FIG. 2.

The network information notification service device 300 according to the present invention includes a resource state information management unit 340 for collecting / managing resource state information on a resource of a predetermined communication network 200 and a predetermined terminal device 100 from the outside. Register the terminal device 100 in response to the information notification service on the basis of the message receiving unit 310 for receiving a subscription request message from the message, and the received subscription request message for requesting subscription of a predetermined information notification service. When the information notification time for the information notification service is reached based on the defined information notification policy, the network information providing unit 320 provides the terminal device 100 with predetermined network usage related information based on the resource status information. It includes.

The resource status information management unit 340 collects / manages resource status information of various resources of a predetermined communication network 200 in which the network information notification service device 300 is located through various paths. That is, the resource state information management unit 340, the communication port resource status information indicating the availability of the communication port resources for the multimedia service of the communication network 200 and the traffic resources according to the communication amount of the communication network 200 At least one of the traffic resource status information may be collected and stored / managed from the communication network 200.

In this case, the communication port resource, preferably means a resource (for example, 16384 ~ 32767) for the RTP (Real time Transport Protocol) port for the multimedia service.

The message receiving unit 310 receives a subscription request message from the terminal device 100 provided from the outside. That is, the message receiving unit 310 receives a subscription request message (eg, a SUBSCRIBE message) from the terminal device 100 provided from the call exchange device 210.

The network information providing unit 320 registers the terminal device 100 in response to the information notification service based on a subscription request message requesting to subscribe to a predetermined information notification service received through the message receiving unit 310.

That is, the network information provider 320 recognizes event information (eg, an event header) included in a subscription request message (eg, a SUBSCRIBE message) from the received terminal device 100, and types of corresponding information notification services. The terminal information (eg, terminal identification information-phone number, terminal ID, etc.) of the terminal device 100 may be registered and stored in the registered terminal information management unit 330 in response to the identified information notification service.

For example, the network information provider 320 recognizes event information (eg, an event header) included in a subscription request message (eg, a SUBSCRIBE message) from the received terminal device 100, and requests a subscription. If it is determined that the type of information notification service is information notification service 1 for receiving network usage related information including available communication port information and location registration retry timing information, the terminal apparatus corresponds to the identified information notification service 1. Terminal information (eg, terminal identification information-phone number, terminal ID, etc.) of 100 will be registered and stored in the registered terminal information management unit 330. Thus, in the registered terminal information management unit 330, information on which terminal device is subscribed to what kind of information notification service will be stored / managed.

When the information notification time for the information notification service is reached based on a predefined information notification policy, the network information providing unit 320 provides the terminal device with predetermined network usage related information based on the resource status information. 100).

That is, the network information providing unit 320 determines whether the information notification time for each type of information notification service is reached based on the predefined information notification policy.

Here, the information notification policy, when a predetermined information notification cycle elapses, attempts to register a location of a terminal device registered corresponding to the information notification service, fails to register a location of the terminal device, and attempts to create a call session of the terminal device. When the call session generation of the terminal device is completed, it is preferable that at least one of occurrences of a communication port connection attempt of the terminal device occurs as reaching an information notification time.

Accordingly, the network information providing unit 320, based on the information notification policy, a terminal device (e.g., 48 hours) has elapsed or registered in correspondence with an information notification service (for example, information notification service 1). Example: 100 attempts to register a location, the terminal device 100 fails to attempt to register a location, the terminal device 100 attempts to create a call session, or the terminal device (eg, 100) completes a call session creation. Alternatively, when the terminal device (eg 100) attempts to access a communication port (eg RTC port), it determines that an information notification time corresponding to the corresponding information notification service (eg information notification service 1) has been reached.

As such, when the information notification time is reached, the network information providing unit 320 generates the network usage related information based on the resource status information based on the information notification policy and subscribes / registers to the information notification service. Example: 100).

That is, the network information providing unit 320 determines at least one of the communication port resource status information and the traffic resource status information based on the information notification policy when the determination result reaches the information notification time corresponding to the information notification service. Generates network usage information including at least one of usable communication port information and location registration retry timing information based on the resource status information to be provided to the terminal device 100 subscribed / registered to the corresponding information notification service. do.

For example, when the determination result reaches an information notification time corresponding to the information notification service (for example, the information notification service 1), the network information providing unit 320 may use communication port information (eg, based on the information notification policy). Generates network usage related information including pre-allocated RTP port information that can pass through the firewall and location registration retry timing information (e.g., after 5 sec has elapsed). Provided to the terminal device (e.g., 100) subscribed / registered to.

Of course, when the determination result reaches the information notification time corresponding to the information notification service (for example, the information notification service 2), the network information providing unit 320, based on the information notification policy, the available communication port information (eg, firewall) Network usage related information including pre-allocated RTP port information that can pass may be generated and provided to a terminal device (eg, 100) subscribed / registered to a corresponding information notification service (eg, information notification service 2). .

Here, the network information providing unit 320, in providing the network usage information to the terminal device 100, the message (eg NOTIFY message) including the network usage information in the XML body in the form as shown in Figure 7 By generating and providing to the terminal device 100, it is preferable to provide network usage information to the terminal device (100).

Here, the reason for including the communication port information usable as network usage-related information is as follows.

After the terminal creates a call session using the SIP protocol, it uses a real time transport protocol (RTP) when it wants to use an audio / video service, which is a multimedia service. In general, RTP consists of ports between 16384 and 32767. Using this dynamic port range makes it difficult to pass through the firewall, so the communication network uses pre-allocated RTP port information that can pass through the firewall for audio or video services. This is because it needs to be delivered to the device.

In addition, the reason for including the location registration retry timing information as network usage-related information is as follows.

When the terminal device wants to use the IMS service, the terminal device must precede the location registration process. However, if the location registration process of the terminal device fails due to lack of communication network resources, the terminal device does not know when the location registration process will be successful in the communication network, and thus continuously attempts the location registration process. This continuous location registration process of the terminal device causes a lot of unnecessary traffic to the communication network and eventually affects the stability of the communication network.

As described above, the network information notification service device 300 according to the present invention subscribes / registers the terminal device 100 requesting to subscribe to the information notification service corresponding to the information notification service, and pre-defined information. Based on the notification policy, the terminal 100 provides corresponding network usage information based on the resource state information of the communication network 200.

Accordingly, the network information notification service apparatus 300 according to the present invention provides the terminal apparatus with network usage related information corresponding to the state of the communication network used by the terminal apparatus subscribed to the information notification service to the terminal apparatus. It is possible to provide an environment that can perform the terminal function based on the use-related information.

Hereinafter, a specific configuration of the terminal device 100 according to the present invention will be described with reference to FIG. 3.

The terminal device 100 according to the present invention includes a subscription request unit 110 for transmitting a subscription request message to a predetermined network information notification service device 300 requesting subscription of a predetermined information notification service, and in response to a subscription request. Receives and stores predetermined network usage related information provided from the network information notification service device 300, and performs the terminal capability based on the network usage related information when accessing the communication network 200 to perform a predetermined terminal capability. It includes a terminal function unit 120.

The subscription request unit 110 provides a subscription request message to the network information notification service device 300 requesting the subscription of a predetermined information notification service to the call exchange device 210.

Here, the subscription request unit 110 preferably generates a subscription request message including event information (eg, an event header) indicating the type of information notification service to be subscribed.

For example, the subscription request unit 110 subscribes to the information notification service 1 for receiving network usage related information including usable communication port information and location registration retry timing information corresponding to the communication network 200. A subscription request message (eg, a SUBSCRIBE message) including requesting event information (eg, an Event header) can be generated, and network usage related information including only available communication port information corresponding to the communication network 200 can be provided. A subscription request message (eg, a SUBSCRIBE message) including event information (eg, an event header) requesting to subscribe to the information notification service 2 for receiving may be generated.

The terminal function unit 120 receives the network usage information provided from the network information notification service device 300 in response to the subscription request by the subscription request unit 110, and transmits the received information to the network utilization information storage unit 130. Save it. That is, in response to a subscription request, the terminal function unit 120 receives a message (eg, a NOTIFY message) including network usage related information from the network information notification service device 300, and extracts network usage related information based on the received message. Network usage information storage unit 130 may be stored.

In addition, the terminal capability unit 120 accesses the communication network 200 and performs the corresponding terminal capability based on the network usage related information when the predetermined terminal capability is performed.

That is, the terminal function unit 120, based on the available communication port information included in the corresponding network use information stored in the network use information storage unit 130 when attempting to connect to the communication port for using the multimedia service ( Example: You can try to connect to the RTC port). Accordingly, the terminal function unit 120 attempts to connect to a communication port (eg, an RTC port) in an available state according to the available communication port information recognized by the network information notification service. Will access

In addition, when the terminal function unit 120 fails to attempt location registration, when the corresponding timing is reached based on the location registration retry timing information included in the corresponding network usage related information stored in the network usage related information storage unit 130, Location registration can be retried. Accordingly, since the terminal capability unit 120 retries location registration after the timing according to the location registration retry timing information recognized by the network information notification service, there is a probability that the location registration attempt fails due to lack of communication network resources. In this large period of time, the location registration retries will be successful after the location registration retry timing has elapsed, when the probability of success is high and the location registration retry timing has elapsed.

As described above, in the network information notification service system according to the present invention, the network information notification service device 300 joins / registers the terminal device 100 that requests the subscription of the information notification service in response to the information notification service. And, based on the predefined information notification policy based on the resource status information of the communication network 200 by providing the corresponding network use-related information to the terminal device 100, the communication network used by the terminal device subscribed to the information notification service Network usage-related information corresponding to the state of may be provided to the terminal device.

Accordingly, the network information notification service system according to the present invention provides the terminal device with network usage related information corresponding to the state of the communication network used by the terminal device subscribed to the information notification service, thereby providing the terminal device to the terminal device itself. By performing the terminal capability based on the network usage-related information provided, it is possible to increase the terminal capability execution efficiency and further increase the communication network management efficiency.
