Description

The present invention generally relates to a method for initiating an extended communication connection between a calling party (A) and a called party (B) in a telecommunications network system including a number of interconnection networks, said extension The communication connection includes a circuit switched connection and a packet switched connection, and the method includes at least:
Setting up the circuit switched connection and the packet switched connection in the extended communication connection between the calling party (A) and the called party (B);
Notifying the called party (B) about the setup of the circuit switched extended connection and the packet switched extended connection;
Processing the setup of the circuit switched connection or the packet switched connection using a circuit switched response (CSR) or a packet switched response (PSR);
including.

  The present invention further relates to a telecommunications network system configured to establish an extended telephone connection between a calling party (A) and a called party (B) and including a number of interconnection networks, The extended telephone connection includes a circuit switched connection and a packet switched connection.

  Furthermore, the present invention relates to a telecommunication device (terminal) that supports an extended connection based on simultaneous (parallel) circuit switched connection (telephone) and packet switched connection.

  In addition, for example, instead of a conventional telephone ringing signal, it is assumed that the called party obtains a pop-up menu indicating additional information such as a business card, a picture of the calling party, and the like. obtain. As another example of an extended connection, it is used by the calling party himself when the called party is unavailable. Instead of a no-answer congestion tone in a traditional telephone call, the caller can obtain more detailed information.

  Recent telecommunications systems include multiple interconnected networks, wired or fixed telecommunications networks such as PSTN (Public Switched Telecommunications Network) or ISDN (Integrated Services Digital Network), and GSM (Global System for Mobile communications). Or a wireless cellular or mobile telecommunications network, such as operating according to the UMTS (Universal Mobile Telecommunications System) standard.

  Currently, telecommunication networks are built on two main technologies: circuit switched and packet switched. In a circuit switched network, a physical path (path) for a single connection between a calling party and a called party is acquired and consumed while the connection continues. In a packet switching network, a relatively small unit of data called a packet is transferred via the network based on a destination address included in each packet. By disassembling communications into packets, many users in the network can share the same data path. (Most traffic on the Internet uses packet switching, which is basically a connectionless network.)

  The remarkable growth in the popularity of the Internet has resulted in considerable interest in using packet switched network infrastructure (eg, based on IP addresses) as an alternative to existing circuit switched network infrastructure used in current telephone networks. . From the viewpoint of a network operator, it is possible to reduce the transfer cost by reducing the traffic cost peculiar to the packet switching infrastructure, and the infrastructure cost per end user can be reduced.

  However, it is not an effective proposal from an economic point of view to give up all investments in the circuit switched network and switch all to the packet switched network. It is possible to support voice, data, video, etc., and to make a huge investment to obtain a worldwide all-packet switching network, the evolution from a circuit-switched network to a practical all-IP network It is a more effective proposal to establish a process. In order to deliver combined / multimedia services, the evolution to all-IP begins with simultaneous / parallel use with circuit-switched and packet-switched networks.

  Simultaneous use of the circuit-switched network and the packet-switched network for initialization between the calling party and the called party results in a ringing signal in both networks. Current technology requires that call signal processing be performed independently in both circuit-switched and packet-switched networks, resulting in slower processing of call signals, less efficient use of telecommunications networks, users Causes more errors due to forgetting to answer the call.

  In current telecommunications systems, high-speed, high-efficiency, error-tolerant responses from the called party, and means for coordinating call processing in an extended connection between a packet-switched network and a circuit-switched network are currently available It is neither known nor implemented.

  An object of the present invention is to provide an improved method and system for performing connection setup or connection rejection with higher speed, higher efficiency, and error tolerance, and in which the packet-switched network and the circuit-switched network coordinate the call processing. And providing a device.

  To achieve the above object, the method according to the invention comprises the steps of processing the circuit switched connection and the packet switched connection setup based on one single response generated at the called party (B). Characterized. In one embodiment of the method, the single response may be a terminal button press or selection of a displayed icon.

  In a particular embodiment of the method according to the invention, the method further comprises the step of rejecting the established circuit switched connection and the packet switched connection based on the generated single response. Or accepting one of the established circuit switched connection and the packet switched connection based on the generated single response and the other of the established circuit switched connection and the packet switched connection. Or generating one of the circuit switched response or the packet switched response based on the single response; and the circuit switched response or the packet switched response. Generating the circuit switched response or the other of the packet switched response based on one of To. These features result in acceptance and rejection of connections, including extended connections, ie, circuit switched connections and packet switched connections, based on a single response generated by the called party (B).

  In a further functional embodiment, the method according to the invention comprises the step of generating the other of the circuit switched response (CSR) or the packet switched response (PSR) in the terminal of the called party (B). It is executed.

  Furthermore, the method is characterized in that the step of generating the circuit switched response or the other of the packet switched response is performed in the telecommunications network system.

  With these features, for example, pressing a single button results in the correct sequence of signals for establishing an extended connection. As described above, for example, depending on which button is pressed, the result is that the extended connection is rejected or a packet switched connection or circuit switched connection is established.

  Further improvement in establishing an extended communication connection between two parties is achieved by a method comprising the step of generating the other of the circuit switched response or packet switched response in the called party (B) terminal. A call such as acceptance or rejection of a circuit switching response or a packet switching response is started, for example, at a circuit switching unit of the terminal, and this information is transmitted directly to the packet switching unit of the terminal without going through the telecommunication network.

  Furthermore, the method according to the invention may comprise the step of generating the other of said circuit switched response or packet switched response in a telecommunications network system. In this embodiment, telecommunications connections are handled via packet-switched and circuit-switched telecommunications networks.

  With these characteristics, for example, the packet switching unit of the terminal can know the response of the circuit switching unit of the terminal. In this case, the information is transmitted via the communication network.

  The telecommunications system according to the invention further processes the circuit switched connection and the packet switched connection based on the generated single response.

It is a schematic diagram of the signaling sequence of the setup of an extended connection when a call acceptance is performed in the Bcs part of a terminal. FIG. 7 is a schematic diagram of a signaling sequence for setting up an extended connection when call acceptance is performed in a packet switching (Bps) part of a terminal (terminal-based solution). The circuit switching unit and the packet switching unit of the terminal are separated devices, and are schematic diagrams of a signaling sequence for setting up an extended connection when call acceptance is performed in the packet switching (Bps) unit of the terminal (terminal base Solutions). FIG. 5 is a schematic diagram of a signaling sequence for setting up an extended connection when a terminal circuit switching unit and a packet switching unit of the terminal are separated devices and call acceptance is performed in the circuit switching (Bps) unit of the terminal.

  In order to solve the above-described object of the present invention, the present invention is incorporated into several embodiments. In the first embodiment, a part of a terminal (such as a circuit switching (Bcs) unit) without using a communication network. Is sent to other parts of the terminal (such as a packet switching (Bps) part). A further embodiment is based on transmitting response information from one part of the terminal (such as the Bcs part) to another part of the terminal (such as the Bps part) via the communication network.

  In these embodiments, the communication terminal needs to be able to execute circuit-switched connection and packet-switched (or data) connection in parallel. Terminal portions corresponding to circuit-switched connection and packet-switched connection are denoted as Bcs and Bps in FIGS. This type of terminal is generally called a DTM (Dual Transfer Mode) terminal.

  In the first embodiment of the present invention (FIGS. 1 and 2), a circuit switched call (1a) and a packet switched call (1b) are transmitted to the communication terminal (20). The user of the terminal can generate a single response (2) to the call, sometimes by voice, for example by pressing the key (11) on the keypad or selecting the displayed icon (11b). it can. It is also possible for the terminal to automatically answer the call after a certain timeout. When the call is accepted by the Bcs part of the terminal, a signal (3) is generated for notifying the circuit-switched network (10a) that the call has been accepted. A signal (4) for notification is generated. The Bps part of the terminal signals (5) that the call is accepted to the packet switched network (10b). When this signaling (5) is automatically generated, there is no possibility that the packet switched network (10b) will continue to wait for a response to the packet switched call. This results in a faster extended connection setup.

  In a similar method (FIGS. 2 and 3), the packet-switched call (1b) and the circuit-switched call (1a) are transmitted by a single response (2 ′; 2 ″ ′) in the Bps part of the terminal (20) (FIG. 2). In this terminal-based embodiment, the Bcs and Bps parts of the terminal (20) may be physically one device (FIGS. 1 and 2), or a wired or wireless connection. May be separate devices (FIG. 3) connected together.

  The above description is not only for accepting both packet-switched calls and circuit-switched calls (1b; 1a), but when circuit-switched calls are rejected and packet-switched calls are accepted, circuit-switched calls are accepted and packet-switched calls are accepted. Is also effective when rejecting and when rejecting both circuit-switched calls and packet-switched calls. This embodiment is new (probably, the terminal's Bps part can request the terminal's OS (Operating System) to be notified (4 ′) when the terminal's circuit switching part answers the call. Vendor-specific) API (Application Program Interface) is required.

  In another embodiment (FIG. 4), which is a network-based solution, responses to circuit-switched and packet-switched calls are sent to the network (10).

  This signal (3 ″ ″) can be monitored by a service in the circuit switched telephone network (10a). The service in the circuit switching network can be notified (4 ″ ″) to the packet switching network (10b). The packet switched network (10b) can send a new message (indicated by a reference number of 4 "") or "ANSWERED" to the Bps part of the DTM terminal. As a result of this signal notification (4 ″), the packet switching unit of the network (10b) can know the acceptance of the call in the Bcs unit of the terminal. This so-called packet switching response (PSR) signal (5 ″ ″) When automatically generated, there is no possibility that the packet switched network (10b) will continue to wait for a response to the packet switched call (1b), resulting in a faster extended connection setup.

  This embodiment requires an extension (standard or proprietary) to packet switched applications and the Bps portion of the terminal needs to be upgraded. Since the packet switching application can be implemented as a software package (for example, an application of J2ME (Java (registered trademark) 2 Platform Micro Edition)), this embodiment should be implemented when each terminal can download the J2ME application. Can do. Since the interaction between the packet switching unit of the terminal and the circuit switching unit of the terminal is processed not via the terminal but via the communication network (10, 10a, 10b), there is no request for API at the terminal.

  This embodiment is also applicable when the circuit switching (Bcs) part and the packet switching (Bps) part are two physically different devices. That is, it is not necessary to mount the packet switching application and the Bcs unit on the same terminal (FIG. 4). Therefore, this embodiment allows the possibility that a packet switched application is executed by a personal computer and a voice call is sent to the telephone. By such a combination, CTI (Computer Telephony Integration) expected for a long time can be realized.
