Method of avoiding concurrent calls, and device applied to same

Abstract

The present invention relates to a system and method for avoiding concurrent calls. Specifically, the method of the present invention includes: confirming, at a terminal device, a connected state of a voice call or a data call at a specific point in time before a transmitting period of a motion maintaining message assigned to a specific application; transferring, to a server device, the motion maintaining message through the data call according to the confirmed connected state of the voice call or the data call to notify the server device of a driving state of the specific application; and transferring, via the server device to the terminal device, a response message with respect to the motion maintaining message transferred from the terminal device.; Thus, concurrent calls or multi-RAB states in which voice calls and data calls are concurrently made may be minimized, and data call connection attempts may also be minimized.

Description

technical field [0001] The present disclosure relates to a method of simultaneously transmitting data, and more particularly, to an apparatus and method for avoiding concurrent calls, wherein the information for holding between a terminal device and a server device is selectively transferred according to the state of a voice call or a data call of the terminal device. The Keep Alive message of the session between them enables to minimize the Concurrent Call (Multi-RAB) state in which a voice call and a data call are performed at the same time, and to minimize an attempt for a data call connection. Background technique [0002] In recent years, various applications have emerged as smart phones have been reinvigorated. Among these applications, there are more and more applications such as messengers that require functions of receiving and sending packets. In particular, in an application in the form of a messenger, the corresponding server should always know the location of t...

Problems solved by technology

[0005] However, in the case of the application in the form of a messenger described above, since push notifications and Keep Alive messages are applied by utilizing data calls, concurrent calls or Multi-RAB that perform voice calls and data calls at the same time are added (Concurrent Call or Multi-RAB) state, and since data calls have a greater impact on network quality than voice calls (coverage decreases according to the increase in required power), the increase in concurrent call states will cause voice drops Call (Call Drop)

[0006] In addition, due to the increasing number and types of applications in the form of messengers recently and applications that require keep-alive messaging using data calls in order to maintain sessions, attempts to connect data calls are increasingly driven by the corresponding applications. to overload the network
