Method, system, and non-transitory computer-readable record medium for providing multiple group calls in one chatroom

A non-transitory computer-readable record medium storing instructions that, when executed by at least one processor, cause a computer system to perform a group call providing method, the method comprising:

• receiving, by the at least one processor, information about a plurality of subgroup call channels generated in response to a first request from at least one member included in a chatroom, from a server, each of the subgroup call channels corresponding to one of subgroups each joined by a portion of members included in the chatroom;
• providing, by the at least one processor, a group call channel list about the plurality of subgroup call channels through the chatroom based on the information about the plurality of subgroup call channels;
• and
• starting, by the at least one processor, a group call through a specific subgroup call channel, from among the plurality of subgroup call channels, in response to receiving a second request for joining the specific subgroup call channel through the group call channel list,
• wherein an identifier is assigned to each of the subgroup call channels,
• the identifier is a quick response (QR) or a uniform resource locator (URL) corresponding to each of the subgroup call channels, and
• the group call providing method further comprises allowing, by the at least one processor, a user of the computer system to join a select subgroup call channel, from among the plurality of subgroup call channels, corresponding to the identifier in response to recognizing the identifier of the select subgroup call channel.

A computer system comprising:

• at least one processor configured to execute computer-readable instructions included in a memory, the at least one processor configured to cause the computer system to,
• receive information about a plurality of subgroup call channels generated in response to a first request from at least one member included in a chatroom, from a server, each of the subgroup call channels corresponding to one of subgroups each joined by a portion of members included in the chatroom;
• provide a group call channel list about the plurality of subgroup call channels through the chatroom based on the information about the plurality of subgroup call channels;
• and
• start a group call through a specific subgroup call channel, from among the plurality of subgroup call channels, in response to receiving a second request for joining the specific subgroup call channel through the group call channel list,
• wherein an identifier is assigned to each of the subgroup call channels,
• the identifier is a quick response (QR) or a uniform resource locator (URL) corresponding to each of the subgroup call channels, and
• the at least one processor is further configured to cause the computer system to allow a user of the computer system to join a select subgroup call channel, from among the plurality of subgroup call channels, corresponding to the identifier in response to recognizing the identifier of the select subgroup call channel.
