ES2284350B1 - METHOD AND SYSTEM FOR THE DEVICE OF CALLS RECEIVED IN THE MOBILE TERMINAL TO A FIXED LINE. - Google Patents

Abstract

Method and system for diverting calls received in the mobile terminal to a fixed line, previously configured in an application resident in the mobile terminal, depending on whether it is within the range of a certain bluetooth device. If it is not within that range, calls are received directly at the mobile terminal, through the management and control of the call through the intelligent network node IN.

Description

Method and system for call forwarding received at the mobile terminal to a fixed line.

Object of the invention

As the name implies, this invention refers to a method that uses the network node intelligent (IN) of the operator to manage and control the zone of coverage (mobile or fixed coverage area -WIFI or Bluetooth- in the that the user defined in the node is found, diverting the incoming calls from the mobile, to the fixed numbering associated with the user of the mobile number, for which it is necessary to install and configure the terminal that acts as fixed, so you can interact with the network node IN.

The objective of the present invention is to avoid to the user use two different telephones to receive calls through control and call management through of the intelligent network node. The user has a terminal unique which has two numbers associated, which are defined in the network node IN, which will detect when the user changes zones network coverage to move on to manage and control the call making the change of numbering being this change transparent for the user: a fixed and a mobile depending on the area of coverage you are in: fixed numbering when in the Bluetooth or Wi-Fi coverage zone; mobile numbering when located in the GSM coverage area. Call control is will perform from the network node IN (Smart Network), which in every moment you will know in which coverage area the single terminal and to what number you should send the call to avoid Let it be interrupted.

When the IN node is detected that the terminal is losing the current coverage through the receipt of access point notifications (Wifi or Bluetooth) and through GSM network notifications, make a second call to the number  with greater coverage, managing the node two parallel calls. The application that will have the terminal that receives the call, allows the acceptance of this second call generated by the node of IN and, once the two calls have been established, IN will switch towards coverage that has more power and secure the call, disconnecting the initial call and keeping the new one. This process is controlled from the IN node, which is responsible for Manage and switch the entire process.

The method through the IN node, allows to maintain  to the user the call regardless of the coverage area where you are, becoming something transparent and devoid of difficulty for the user.

Background of the invention

Currently a user has several terminals associated each to a numbering either mobile or fixed.

The fixed terminal requires that the user be always within the coverage area offered by the operator of fixed (that is, inside the home). And this fact prevents the user have mobility outside that coverage area, especially when you receive a call to the traditional landline number at the time I just had to leave home.

Description of the invention

The proposed method makes the user independent of these actions through the single terminal, configured in the node IN (intelligent mobile or fixed operator network) with both numbering associated with the user. The operator is the one who configure the single terminal and provision the user in the IN node and the numbers associated with it.

The present invention aims to avoid the user  use two different phones to receive calls.

The Handover function consists of the transfer  of carrier connection between base stations due to terminal movement. This function is an operation complex, especially from the point of view of the network, since it involves a change of physical channels, whether radio and / or terrestrial, during a call holding that call. The present invention is applied to performing said handover function between Bluetooth / Wifi and GSM coverage areas, using IN in an environment of a single Bluetooth terminal (CTP) extensible to other environments (WIFI, SIP).

The method object of the present invention is set in a real-time session, where the single terminal of user is registered in the IN node within a zone of coverage. The IN node, while the call is established is the person in charge of monitoring the Bluetooth / Wifi coverage area or GSM in which the terminal is located. Depending on the area in the If the terminal is registered in IN, the node will assign it transparent to the user if it is in a Bluetooth / Wifi zone, a  fixed numbering (like that of traditional operators) and will receive and generate calls with said numbering, applying the corresponding pricing. At the time the coverage begins to degrade, a message (via IP) is sent to the IN node and This detects that the user has entered the GSM coverage area, to from that moment IN takes control of the call, and switches the call and assigning the new numbering to the terminal: change the Fixed numbering by mobile numbering.

For the development of this method the terminal mobile requires the installation of an application that informs the user if it is in coverage through a local terminal or in GSM coverage, adding a small icon on the screen in House shape or traditional network symbol. It will be necessary perform the implementation in the IN node, where it will be registered Handover GSM-Wifi / Bluetooth service.

The single terminal application allows inform the user at any time in the coverage area in the that is, providing mobility. The terminal initially it must match the access point (in both cases, CTP or WIFI / SIP) and in the case of WIFI / SIP, you must register with the softswitch that will serve you and also match the access point.

According to a characteristic of the present invention, in the Handover of the calls the following elements:

to)

A single terminal, which can be a CTP terminal, class 1 Bluetooth, or a single WIFI / SIP Terminal properly configured.

b)

A Bluetooth access point (for the CTP terminal) or a point of WIFI access and a softswithc (for the WIFI / SIP terminal). If CTP, it can be a dedicated access point for this application of a USB "dongle" connected to a laptop, or any other device that has wireless technology Bluetooth

C)

A Smart Network IN node, no matter who has the node, it can be the fixed operator or the mobile operator, you just have to ensure the correct provisioning of the user and the associated numberings to the.

d)

A line (numbering) of fixed and another of mobile.

We must distinguish different scenarios according to the  type of technology used in the single terminal and according to the area of coverage where the call is made. The scenarios that are They can give according to the type of terminal:

to)

Single WIFI / SIP terminal: the terminal must be paired with your access point and must be registered on the softswitch that offers the fixed numbering service, so that when the terminal enters the local coverage area (WIFI / SIP) can receive and make calls that enter the number permanent

b)

Single CTP terminal: the terminal must Be paired with your Bluetooth access point. When the user Enter the Bluetooth coverage area, the access point will notify the change of state to the IN node.

The scenarios according to the coverage area can  be:

to)

Handover Bluetooth / WIFI-SIP to GSM: a generated call or received in the fixed network, it will become transparently for the user in a mobile numbering call, allowing mobility.

b)

GSM handover to Bluetooth / WIFI-SIP: a call generated or received in the mobile network, it will become transparently for the user in a call to fixed numbering, without perceiving any cut, Holding the call

For the best understanding of how much is left described herein are accompanying drawings in the which by way of example represents a practical case of realization according to the method.

Description of the figures

Figure 1 shows a schematic view of the Handover method development through IN.

Preferred Embodiment of the Invention

As shown in figure 1 the handover  between a bluetooth and GSM coverage zone, it requires a Single terminal and a bluetooth access point, with which it is couplet

The method of the present invention requires to  its development that an application be installed in the single terminal that allows the user to inform the coverage area in which You are making the call. This application has a symbol in the form of a house, which indicates that it is in local coverage. It also has a small menu that serves to enter the parameters necessary to match the access point.

It is also necessary to have:

to)

Two numberings, one mobile and another fixed.

b)

Bluetooth access point name which defines the coverage and name of the softswitch where it will be registered the terminal in the case of being WIFI / SIP.

C)

Associate through the settings in the IN node the numberings of each user, as well as the type of coverage in which it is located (GSM zone / zone bluetooth / WIFI-SIP). Logic Configuration service, implementation, control and management of the Handover during a call.

d)

Configure the generation from the node IN of a second call at the time of changing zone coverage preventing the call from being lost.

The service method would be as follows:

The terminal (Bluetooth or WIFI / SIP) with a call registered in the IN node with GSM coverage, reaches a coverage area defined in IN as local. At that time, the terminal notifies the IN node, detects that the user is going to experience a change in coverage (greater reception power in  the local zone than in the GSM zone). Because all the control and Handover management is done from IN, it changes the profile of the user locally generating a second call (keeping the current call) to fixed numbering defined with coverage local. Once the second call is established, IN ends the process of the first call, switching to the new call generated. For practical purposes, the call was being made in a GSM coverage zone with mobile numbering, once entered local coverage area, the terminal application receives the order from the numbering IN node. With the new numbering and with the notification and detection of the change of zone of coverage transparently receives a call to fixed numbering defined in the local area, thus switching and continuing the call.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not involve an alteration of the essential features of the invention claimed in continuation.
