Description

Wired and wireless voice communication control system and method using MQTT function {System and method for controlling voice communications in a fixed mobile convergence using MQTT protocol}

The present invention relates to fixed mobile convergence (FMC) technology, and more particularly, to a wired/wireless voice communication control system and method.

FMC (Fixed Mobile Convergence) refers to the integration or convergence of a fixed network and a mobile network, that is, a wired network and a wireless network. It can be said that the service is provided by In general, the FMC service uses a short-range wireless communication network such as a wireless local area network (WLAN) (eg, WiFi network) indoors using an FMC terminal as a mobile terminal, and a long-distance wireless communication network such as a 3G/LTE mobile communication network outdoors As a technology for performing communication using a (mobile) communication network, it refers to a terminal communication service that selectively uses a plurality of access networks to perform communication. That is, the FMC service is a service that allows a mobile phone terminal to be used as a landline phone (external phone) regardless of whether it is indoors or outdoors.

Accordingly, the FMC terminal has at least two or more wireless interfaces, for example, the two or more interfaces may be interfaces capable of accessing a mobile communication network and a WiFi network, respectively. From the user's point of view, the FMC service can be provided through the WiFi network by using such an FMC terminal, thereby saving service charges, and from the network operator's point of view, the load on the mobile communication network can be reduced. However, since the WiFi network is used by many users in the same frequency band, the problem of interference is serious and the call quality for real-time voice calls is not guaranteed. It can provide stable quality FMC service regardless of However, recently, as a data rate system that charges according to data usage instead of providing unlimited voice calls has been released, the cost of using the data network rather than the voice network is inverted. In such a data-oriented environment, the economic cost burden of FMC subscribers increased, which made it hesitant to make a decision to introduce FMC for companies that want to achieve increased business mobility and productivity through FMC.

Korean Patent Registration No. 10-1577170, in order to solve this problem, optimizes the call cost and call quality by efficiently controlling the call path for the voice communication call sent or received from the user terminal during the wired/wireless convergence service in the wired/wireless convergence system. An apparatus and method for controlling voice communication in a wired/wireless convergence system have been proposed. However, this patent discloses a first call path forming unit for receiving a voice (outgoing) call sent from a user terminal through a voice telephone network and forming a first communication path with the user terminal, and incoming and outgoing information for receiving an incoming phone number. and a second call path forming unit for forming a second call path with the other party's called terminal through the voice telephone network based on the received called incoming phone number together with the receiving unit, wherein the second call path forming unit includes a user through the data network. A second call path is formed by notifying the other party's called terminal (phone number) that there is a call from the FMC extension phone number of the terminal, and by the notification, the other party's called terminal makes a call to the FMC server through the voice telephone network. That is, as the second call is formed in a manner of notifying (pushing) that a call is made to the other party's called terminal, overload of the FMC server cannot be avoided and frequent errors are caused in smooth call transmission and reception.
