Abstract

A common problem in mobile phone networks is a dropped call due to poor signal. In this event users typically call each other back but get failed calls as both lines are engaged try to contact the other. This article proposed a solution to this problem whereby two calls being made to each other are reconnected.

A method of reconnecting broken phone calls

When we are speaking on our mobile phones, and suddenly the call is dropped for

whatever reason, most likely signal dropped below a certain level needed to hold the call. Next both parties who were speaking try to call each other back, but they then get each other's voicemail for one of two reasons - one of them is still without reception, or they are both trying to connect to each other at the same time, basically knocking each other on the head with requests and thus will not get connected.

    This article proposes a potential solution for the scenario of not having the call connected due to both parties attempting a reconnect at the same time. The current solution is to, before the call drops one party says "I'll call you back", however, this has its own problems in that if you did not get time to say that, then its likely both people will try calling back almost immediately resulting in a failure to connect the call. A better solution is required because it is very inconvenient and frustrating for mobile end users to have this scenario - which happens more often

than you would expect!

    The proposed method is a software based extension to existing mobile cell towers where the scenario described above of a call disconnecting followed by 2 parties trying to reconnect simultaneously is caught, and a connection is made between the parties automatically, avoiding the unnecessary dance between calling and pausing as you try to reconnect the phone call.

The advantage to this invention are numerous:


Reduction in failed calls post initial failure - this is in the interests of mobile


1.

phone providers as they avoid the processing overhead of multiple duplicate attempts at calls which will always fail due to the other participant being engaged.

Calls are reconnected more immediately - this means the cell towers themselves


2.

are having one of the 56 concurrent phone calls on 1g, or 168 concurrent phone calls on 2g[1], etc, freed up more quickly as less time is being spent with failed call attempts leaving more channels free for other mobile users.

The end users making the calls get connected more quickly, resulting in a less


3.

painful mobile experience allowing them to get on with their conversation
More time is spent speaking than connecting, for the mobile phone providers,


4.

this means more money (or more free minutes) is being spent resulting in the potential for further money to be made from the end user making the call instead of a user becoming frustrated and giving up when trying to connect a call.

    This system would work by having a firmware upgrade to the base station used for mobile cell towers. A standard broadly used base station would be the Samsung MBS [2] where firmware upgrades control everything in the tower, this

would not be an expensive or complicated upgrade.

    The component which would be extended with some extra logic would look as follows:...
