Description

Electronic devices and methods for providing message chat services

Various embodiments of the present disclosure relate to an apparatus and method for provisioning a message chat service in an electronic device having a subscriber identification module (SIM, hereinafter referred to as 'SIM').

Efforts are being made to commercialize a ^{next-generation (eg, 5 th-} generation or pre-5G) communication system to meet the growing demand for wireless data traffic after commercialization of 4G (4 ^{th-generation) communication systems.} For example, the 5G communication system or the pre-5G communication system is called a system after the 4G network (beyond 4G network) or the LTE system (post LTE).

In order to achieve a high data rate, the 5G communication system has been implemented in a high-frequency band. In order to mitigate the path loss of radio waves and increase the propagation distance of radio waves in the high frequency band, in 5G communication systems, beamforming, massive multi-input multi-output (massive MIMO), Full dimensional MIMO: FD-MIMO), array antenna, analog beam-forming, or large scale antenna technologies are being applied.

In addition, for network improvement of the system, in the 5G communication system, an evolved small cell, an advanced small cell, a cloud radio access network (cloud RAN), and an ultra-dense network (ultra-dense network) , device to device communication (D2D), wireless backhaul, moving network, cooperative communication, coordinated multi-points (CoMP), or interference cancellation Such technological developments are being adopted.

In addition, in the 5G system, advanced coding modulation (ACM) methods such as hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC), and advanced access technologies such as filter bank multi carrier (FBMC), NOMA (non-orthogonal multiple access), and sparse code multiple access (SCMA) may also be applied.

The 5G system, in which the technology to improve communication performance discussed above, is introduced, can provide various services requiring high quality, high speed, or stability. For example, it is possible to support a multimedia service supporting high quality or high capacity or an Internet of things (IoT) service that may require a lot of traffic.

In addition, in the 5G system, the communication performance can be improved so that the exchange of various media data as well as the chat service by text message in real time, which was serviceable in the previous system, can be more diversified and high-capacity information can be processed at high speed. became

RCS (rich communication service) may be one of the representative message chat services provided by the 5G system. For example, RCS may provide enhanced messaging services adopted by the global system for mobile communications association (GSMA). The RCS is, for example, a third party (3 ^rd party) can support one of the native Messages app (native message application) without the app-one chat, group chat, read receipts, and features such as large file transfers.

In addition, in order to use a message chat service such as RCS, a procedure for authenticating whether a user is a normal subscriber who can use the service is prepared. The procedure for authenticating the subscriber may also include a procedure for setting the subscriber's authority for the message chat service. However, since a procedure for authenticating a subscriber is not uniform in a message chat service such as RCS, a situation may occur that causes inconvenience when a subscriber uses the message chat service. For example, if subscriber identification information required for the description of authority of the message chat service is not stored in the SIM provided in the electronic device, the electronic device cannot normally complete the registration procedure for using the message chat service.

According to various embodiments of the present disclosure, there may be provided an apparatus and method for allowing an electronic device to perform a registration procedure for the message chatting service in a situation where subscriber identification information required for the message chatting service is not stored in the SIM. .
