Embodiment 1

[0084] figure 1 It is a diagram showing the network configuration and connection method of the gateway device according to the first embodiment of the present invention. in figure 1 The mobile terminal 120 is a voice telephone terminal connected to the mobile circuit switching network 130. The mobile terminal 120 can directly use an existing voice phone terminal. The mobile terminal 120 is connected to the mobile circuit switching network 130, and exchanges call control signals and voice signals with the circuit switch 135 via the wireless network controller 138. The mobile terminal 120 exchanges call control signals based on circuit switching with the circuit switch 135 via the wireless network controller 138. As a voice codec, it is equipped with, for example, an AMR (Adaptive Multi-Rate) voice codec. 12.2kbps bit rate compression coded bit stream. Among them, the detailed content of the AMR speech codec can refer to the 3GPP (Third Generation Partnership Project) TS26.090 ...

Embodiment 2

[0113] Next, the second embodiment of the present invention will be described. image 3 It is a diagram showing the structure of the second embodiment of the present invention. in image 3 Neutralization figure 2 The same components are marked with the same reference numbers. Below, omit and figure 2 In the description of the same elements in the above-mentioned embodiments, only the differences are described.

[0114] in image 3 Since the voice codecs carried by the mobile terminal 120 and the mobile terminal 150 are different, in addition to the protocol conversion, the voice coding method must be converted in the gateway device 110.

[0115] The control / analysis unit 180 analyzes the information input from the call control / conversion unit 160, and if the voice coding method (voice codec) between the terminals is different, the protocol conversion unit 200 and the voice code converter 190 A conversion instruction is issued, so that in addition to the protocol conversion in ea...

Embodiment approach

[0129] The configuration and operation of other embodiments of the present invention will be further described. In the present invention, the gateway device (second gateway device) for interconnecting the mobile circuit switching network and the IMS network performs operations such as RNC to connect to access points or HNBs or HeNBs installed in houses, etc. A terminal connected to an access point or an HNB or HeNB, a terminal connected to the second gateway device via an RNC, and a terminal connected to the second gateway device via the IMS network realize mutual connection of voice communication.

[0130] In the present invention, the gateway device receives a call control signal based on a predetermined protocol from a femtocell base station access point or HNB or HeNB in ​​a carrier based on a mobile high-speed network (such as an IP carrier) and uses the protocol or payload format At least one of the data packets storing the voice data, in the protocol of the call control si...

Abstract

Provided is a gateway device, method and program which permit voice communications to be carried out between a terminal, which connects a home access point or the like to a circuit exchange of a mobile circuit exchange network by operating in the manner of a radio network controller (RNC) and is connected to the access point, and an existing terminal connected to the circuit exchange. A gateway device (110) connects an installed access point (145) to a circuit exchange (135) (or a second gateway device) on a mobile circuit exchange network (130) and carries out voice communication therewith, wherein said gateway device (110) receives, from the access point (145), a voice control signal and/or a packet in which voice data has been stored by means of a preset protocol or payload format, and the gateway device (110) changes the voice control signal protocol and/or the packet protocol or payload format to a protocol which is the same as the circuit exchange protocol used when the radio network controller (RNC)(138) connects to the circuit exchange (135) (second gateway device), and the gateway device (110) outputs said protocol to the circuit exchange (135) (second gateway device). After inputting a voice processing signal which uses the same protocol as the protocol used when the circuit exchange (135) (second gateway device) outputs to the radio network controller (138) and/or a voice signal which used the same protocol, and after changing the protocol of the voice processing signal and/or the voice signal which have been input, said gateway device (110) outputs the signal to the access point (145).

Description

Technical field [0001] (Description of the relevant application) [0002] The present invention is based on the priority claims of Japanese Patent Application: Japanese Patent Application No. 2009-033045 (application filed on February 16, 2009) and Japanese Patent Application: Japanese Patent Application No. 2009-074884 (application filed on March 25, 2009) , The entire content of this application is included in this specification by reference. [0003] The present invention relates to a gateway device, method and program, and more particularly to a method for connecting an access point of a femtocell base station, Home NodeB or Home eNodeB, etc., to a switch on a mobile circuit switching network via a gateway to achieve access Device, method and program for interconnection of VoIP voice on point and voice telephone on mobile circuit switching network. Background technique [0004] Now, in mobile phone terminals with third-generation W-CDMA technology and mobile networks, voice pho...
