Description

  The present invention relates to signal processing for network and service control, and more particularly, to a network layer based integrated signal processing apparatus and method for an IP (Internet Protocol) based wired and wireless integrated network.

  In order to connect and control end-to-end services generally in a communication network, call control and connection control are separated. In the case of call control, a call is identified, set up and released, and after checking the location and consistency of the transmitting and receiving terminals, signal processing, that is, negotiation for service connection such as QoS (Quality of Service) by signaling (signaling). Proceed. In the case of connection control, after call control as described above is executed, functions such as resource control for a physical connection path between end points are executed.

  However, at present, the functional separation of call control and connection control on an IP network is ambiguous, and call control and connection control are applied in duplicate.

  The hierarchical structure pursued in the next generation communication network (Next Generation Network: NGN) is composed of a service control layer and a transmission control layer. The service control layer is in charge of IMS (IP Multimedia Subsystem) -based service control. The transmission control layer executes the location management and mobility control of the IP terminal through the MMCF (Mobility Management Control Function) of the ITU-T (International Telecommunication Union-Telecommunication Standardization Sector), and the control of the RACF (reset control). To execute QoS control between terminals and resource control on the path.

  However, such a hierarchical structure has a disadvantage in that the functions for each hierarchy overlap. Specifically, the service control layer performs functions such as managing the location of the other party by the IMS user registration function and setting the availability of the other terminal for call setting between terminals. Here, IP mobility control is performed in the transmission control layer, which is a network layer, but this function performs IP terminal location management separately from IMS to support IP connectivity between terminals. . Therefore, it is considered that such a function is executed in duplicate in the service control layer and the transmission control layer.

  In addition, although IMS performs policy-based QoS control for individual calls (SIP Sessions), with the development of network equipment functions, the transmission control layer also uses 5-tuple information on IP traffic. By enabling automatic QoS control for individual traffic flows, it is considered that QoS control functions overlap between layers.

  In addition, let's take a closer look at the current control structure for IP network service traffic. Service traffic of application services related to SIP (Session Initiation Protocol) signaling procedures such as VoIP (Voiceover Internet Protocol) is allowed to enter the network under the control of IMS, but what is SIP signaling procedures like WWW services? Irrelevant service traffic flows into the network without any sanctions as long as the user is connected to the network. For this reason, the current control structure is a structure that cannot block the contamination of the network by harmful traffic or unauthorized traffic. Therefore, there is a need for a function capable of integrated control of SIP / non-SIP based services.

  On the other hand, in current IP networks, there are SIP protocol-based signaling for service connection, signaling for VPN (Virtual Private Network) setting, signaling for QoS control, signaling for mobility control, etc. In fact, each function has a complicated control structure for executing a separate signaling procedure.

The IP address of the packet transmitted from the terminal 3 and the terminal information are bound and recorded, and it is determined whether or not the terminal 3 is connected to the IP network.

  The terminals 3-1, 3-2,..., 3-n may be provided with a network service in a client / server form and a network service in an end-to-end communication form with other mobile terminals. Further, the terminal 3 according to the embodiment of the present invention is equipped with a client capable of processing an integrated signal for security control, QoS control, mobility control, connection control, and VPN control.

  In such a network environment, the integrated signal processing apparatus 10 according to the embodiment of the present invention is connected to the IP network 1 in order to simultaneously process various controls regardless of any of a wired terminal and a wireless terminal. It works with the management server 20 and the user policy server 30.

  The user management server 20 manages address information given to the user so that the user can be recognized together with the IP address in the network. Specifically, the user management server 20 stores and manages various types of information for subscribers who can connect to the IP network 1 according to the embodiment of the present invention. In particular, the user management server 20 stores a unique address and a location address provided from a terminal. Binding and storing and managing as address information. The address information of the terminal according to the embodiment of the present invention will be described in more detail later. Further, the user management server 20 may include a user database 21 for managing address information of the user's terminal, and the address information obtained from the terminal is stored in the user database 21 corresponding to the corresponding user ID and Managed.

  As shown in FIG. 2, the integrated signal processing apparatus 10 according to the embodiment of the present invention includes a first processing unit 11 and a second processing unit 12.

  The first processing unit 11 obtains address information from the terminal, stores it, manages it, and transmits the obtained address information of the terminal to the user management server 20 so as to be registered and managed. Specifically, the terminal 3 binds its own unique address and the position address and binds to the integrated signal processing device 10 when the position address changes according to the change of the subscriber network connected to the IP network 1 or by movement. To the first processing unit 11. The first processing unit 11 voluntarily registers the unique address and location address of the terminal obtained as described above or provides them to the user management server 20 for management.

  The address information of the terminal according to the embodiment of the present invention includes a unique address uniquely assigned to the terminal and a location address given to the terminal according to a location of the wired subscriber network or the wireless subscriber network to which the terminal is connected. It consists of a dual address system. Here, the unique address may be assigned when the user first subscribes to the service from the communication carrier, or is assigned from a dynamic address configuration protocol (DHCP: Dynamic host configuration protocol, not shown) at the time of network connection. Information used to identify the terminal and may be an IP address (terminal ID).

  The terminal address information may be managed in correspondence with user identification information for identifying the user of the corresponding terminal, that is, the user ID. The user ID is unique information for identifying the user when the user subscribes to a network service (for example, a wired Internet service). The user ID and the unique address are used in an authentication process at the time of network connection.

Since the location address is used as a transmission address where data traffic is actually transmitted, it may be named a transmission address. When the terminal 3 is connected to the network or moves to another network, the location address is changed according to the connected subscriber network, and the location address and the unique address to be changed are bound to be integrated with the user management server 20.

Specifically, the IP connection between the terminal of the first user, i.e., the first user terminal (e.g., 3-1) and the terminal of the second user, i.e., the second user terminal (e.g., 3-2). Execute.

  On the other hand, the second processing unit 12 is configured to provide the requested service between the terminals to which network connection including IP connection is performed by the first processing unit 11. That is, IP-based services including VoIP calls, streaming data transmission services, etc. are registered between terminals, data traffic using an application protocol corresponding to the registered services is permitted, and services requested between terminals Ensure that data traffic is sent.

  Next, based on such a structure, an integrated signal processing method according to an embodiment of the present invention will be described.

  First, in the embodiment of the present invention, integrated signal processing for a VoIP call between a first user and a second user will be described.

  The first user terminal, i.e., the first user terminal 3-1 and the second user terminal, i.e., the second user terminal 3-2, are connected to the IP network 1, or the subscriber network to be connected is changed by movement. When the location address is changed, it binds and provides its own unique address and location address. The bound unique address and location address of each terminal are transmitted to the integrated signal processing device 10 via the network connection device 4 and provided to the integrated signal processing device 10 and the user management server 20 stored and managed. And managed by at least one of the methods stored, registered and managed.

  As shown in FIG. 3, among the terminals managed by at least one of the integrated signal processing apparatus 10 and the user management server 20 whose address information is connected to the IP network 1, the first user terminal 3- When 1 tries to make a VoIP call with the second user terminal 3-2, the following processing is performed. Here, it is assumed that the first user terminal 3-1 and the second user terminal 3-2 have already been authenticated.

  3a and 3b are flowcharts illustrating an integrated signal processing method for a VoIP call according to the first embodiment of the present invention.

  As shown in FIG. 3a, first, the first user terminal 3-1 transmits a request for a VoIP call to the second user terminal 3-2 to the integrated signal processing apparatus 10 (S100). In this case, integrated signal processing in which a call request message for VoIP call is connected to the IP network 1 via a network connection device (for example, 4-1) of a subscriber network to which the first user terminal 3-1 is connected. The call request message transmitted to the device 10 includes the location address of the first user as the source address, that is, the transmission address and the ID of the second user as the destination.

  FIG. 4 is a diagram illustrating a structure of a call request message according to the embodiment of the present invention.

  As shown in FIG. 4, the call request message according to the embodiment of the present invention includes a source address and a destination address. That is, it includes the location address of the first user terminal 3-1 that is the source requesting the call, that is, the transmission address, and the ID for the second user that is the destination to be called. Here, the ID of the second user may be in a general character string form or a URI (Uniform Resource Identifier, userb@aaa.bbb) form.

  In addition, the call request message includes a usable QoS class and a service type indicating the type of application service to be requested (Service Type). Here, since the user requested a VoIP call, the service type is “VoIP”. In addition, when the service type is VPN, the integrated signal processing apparatus 10 may set a VPN between the first user and the second user terminal, and set resources necessary for the VPN.

  On the other hand, if the call request message including the information as described above is received, the integrated signal processing apparatus 10 receives the transmission address of the first user terminal 3-1 from the received call request message, as shown in FIG. 2 user IDs are obtained (S110). Then, the integrated signal processing apparatus 10 requests the unique address of the second user terminal 3-2 while transmitting the obtained second user ID to the user management server 20 (S120). The user management server 20 searches the user database 21 based on the ID of the second user provided from the integrated signal processing device 10 and obtains the unique address of the terminal corresponding to the ID of the second user to obtain the integrated signal processing device. 10 (S130).

  The integrated signal processing apparatus 10 obtains the unique address of the second user to be talked, and then is bound with the unique address of the second user from the address information of the terminal that is independently managed by the first processing unit 11. Position address, that is, a transmission address is obtained (S140). Accordingly, the integrated signal processing apparatus 10 obtains the address information of the second user, that is, the unique address and the transmission address.

  Next, the integrated signal processing apparatus 10 confirms the service policies of the first user and the second user in order to set a session between the first user terminal 3-1, the second user terminal 3-2 and the second. To do. For this purpose, the integrated signal processing apparatus 10 obtains information on the service policy of the user while transmitting the ID of the first user and the ID of the second user to the user policy server 30. The user policy server 30 searches the policy database 31 based on the transmitted first user ID and second user ID, and allocates resources and traffic corresponding to the first user ID and the second user ID, respectively. The service policy control information for the allowable amount is searched and transmitted to the integrated signal processing apparatus 10 (S150).

  After confirming the service policy, the integrated signal processing apparatus 10 requests the second user terminal 3-2 for IP connection based on the transmission address of the second user and receives a response (S160), or the first user terminal 3 -1 requests IP connection and receives a response (S170). Upon receiving a response from the first user terminal 3-1 and the second user terminal 3-2 for such IP connection, the integrated signal processing device 10 receives the first user terminal 3-1, the second user terminal 3-2, Policy control and resource control during the period are executed (S180).

  Specifically, the integrated signal processing apparatus 10 determines the first user terminal 3-1 and the second user terminal 3-2 based on the service policy control information of the first user and the second user obtained from the user policy server 30. Perform service policy control and resource control between sending addresses.

  When the network state is a state where the VoIP call service requested by the user can be processed, the IP address connection process between the first user terminal 3-1 and the second user terminal 3-2 is completed. (S190). On the other hand, the integrated signal processing apparatus 10 queries the user policy server 30 about the QoS class included in the call request message, receives a response indicating whether the QoS class matches the SLA condition of the corresponding user, and the QoS class matches the SLA condition. In this case, it is determined that the VoIP call service requested by the user can be processed, and the IP connection is completed. On the other hand, if the QoS class does not meet the SLA condition, the corresponding VoIP service is rejected and the IP connection is canceled.

  Next, referring to FIG. 3b, the integrated signal processing apparatus 10 registers a VoIP service between the first user terminal 3-1 and the second user terminal 3-2 (S200). Then, the network connection device 4 of each subscriber network is notified that permission for the traffic using the application protocol is permitted (S210). Here, the integrated signal processing apparatus 10 includes the contents related to the VoIP service between the first user terminal 3-1 and the second user terminal 3-2, that is, address information and service of the first user terminal and the second user terminal. Stores that the VoIP service is performed in accordance with the policy control information.

  As a result, end-to-end VoIP communication, that is, VoIP communication between the first user terminal 3-1 and the second user terminal 3-2 becomes possible (S220). The network connection device 4 of the subscriber network includes 5 tuple information (source address, destination address, protocol, source port) included in the IP header of the VoIP traffic packet using the corresponding application protocol for VoIP communication. , Destination port) is used to determine whether or not to permit entry for a predetermined VoIP traffic.

  While the VoIP data traffic is being transmitted / received between the first user terminal 3-1 and the second user terminal 3-2, the second user terminal 3-2 transmits video to the first user terminal 3-1. When requesting such streaming data transmission (S230), the integrated signal processing apparatus 10 confirms whether or not the IP connection between the first user terminal 3-1 and the second user terminal 3-2 is maintained. . When the IP connection is maintained, a streaming service capable of transmitting streaming data between the first user terminal 3-1 and the second user terminal 3-2 without registering a separate process is registered (S240). The network connection device 4 of the subscriber network to which the two-user terminal is connected is notified that permission for traffic using an application protocol for streaming data transmission is permitted (S250). As a result, the network connection device 4 permits entry of traffic using the corresponding application protocol. Also in this case, it may be determined whether or not the corresponding traffic is to be introduced using the 5-tuple information included in the header of the received traffic. Thereby, streaming data transmission is performed between the first user terminal 3-1 and the second user terminal 3-2 (S260).

  Next, an integrated signal processing method for a VoIP call between the first user and the second user according to the second embodiment of the present invention will be described.

That is, in the first embodiment described above, when the integrated signal processing apparatus 10 completes the IP connection without a separate process, the VoIP service between the first user terminal 3-1 and the second user terminal 3-2 is registered. In the second embodiment, since only the IP connection is made by the connection request of the first user terminal 301, the corresponding service is provided by the service request from the first user terminal 3-1. In this example, the first user terminal 3-1 requests a VoIP call, and when the second user terminal 3-2 accepts such a request, the VoIP service is registered. It is not limited.

  More specifically, after the IP connection is completed, as shown in FIG. 5b, the integrated signal processing device 10 requests the VoIP call from the first user terminal 3-1 to the second user terminal 3-2. When the message is received (S500), after confirming the transmission address of the second user terminal 3-2, the VoIP call with the first user terminal 3-1 is requested to the second user terminal 3-2. Thereafter, when a response to the VoIP call request is received from the second user terminal 3-2 (S510), the integrated signal processing apparatus 10 determines whether the first user terminal 3-1 and the second user terminal 3-2 are connected. VoIP call service is registered (S520).

  If such a service registration process is completed, the call signal processing apparatus 10 is connected to the first user terminal 3-1 and the second user terminal 3-2 in the same manner as in the first embodiment described above. The connection device 4 is notified that the traffic using the application protocol for the VoIP call is permitted (S530), and the VoIP call between the first user terminal 3-1 and the second user terminal 3-2 is started. (S540).

  Thereafter, when a streaming data transmission request is received from the first user terminal 3-1, as in the first embodiment described above, a streaming service is registered and traffic using the corresponding application protocol is received. It permits, and the streaming data transmission between the 1st user terminal 3-1 and the 2nd user terminal 3-2 is made (S550-S580).
