Method and system for inter-group communication in a wireless P2P network

A first device operating in one of a plurality of peer-to-peer (P2P) groups included in a wireless P2P network, the first device comprising:

• a memory storing a set of instructions for performing inter-group communication;
• and
• a processor configured to execute the set of instructions to:
• disconnect from a first P2P group in response to reception of an instruction from a first group owner of the first P2P group;
• send a connection request as a trigger for inter-group communication to a second group owner of a second P2P group so as to join to the second P2P group,
• wherein the second group owner instructs a second device included in the second P2P group to initiate connection switching from the second P2P group to the first P2P group in synchronization with the trigger;
• exchange data between the first device and the second P2P group;
• and
• after a predetermined time interval has elapsed, disconnect the first device from the second P2P group so that the first device joins back to the first P2P group,
• wherein in synchronization with the first device switching to the first P2P group, the second device disconnects from the first P2P group so that the second device joins back to the second P2P group.

A second device operating in one of a plurality of peer-to-peer (P2P) groups included in a wireless P2P network, wherein a first device included in a first P2P group receives an instruction from a first group owner of the first P2P group, the second device comprising:

• a memory storing a set of instructions for performing inter-group communication;
• and
• a processor configured to execute the set of instructions to:
• disconnect from a second P2P group in response to reception of an instruction from a second group owner of the second P2P group, wherein the second group owner has received a connection request as a trigger from the first device;
• and
• send a connection request to the first group owner of the first P2P group so as to switch its connection from the second P2P group to the first P2P group;
• exchange data between the second device and the first P2P group;
• and
• after a predetermined time interval has elapsed, disconnect the second device from the first P2P group so that the second device joins back to the second P2P group,
• wherein in synchronization with the second device switching to the second P2P group, the first device disconnects from the second P2P group so that the first device joins back to the first P2P group.

A non-transitory computer readable medium storing a program that comprises instructions for a first device to perform:

• disconnecting from a first P2P group in response to reception of an instruction from a first group owner of the first P2P group;
• and
• sending a connection request as a trigger for inter-group communication to a second group owner of a second P2P group so as to join to the second P2P group,
• wherein the second group owner instructs a second device included in the second P2P group to initiate connection switching from the second P2P group to the first P2P group in synchronization with the trigger;
• exchanging data between the first device and the second P2P group;
• and
• after a predetermined time interval has elapsed, disconnecting the first device from the second P2P group so that the first device joins back to the first P2P group,
• wherein in synchronization with the first device switching to the first P2P group, the second device disconnects from the first P2P group so that the second device joins back to the second P2P group.
