Abstract
Systems and methods for simultaneous calling in a cellular communications system are disclosed. In one embodiment, a method performed by a first wireless communication device for simultaneous Internet Protocol (IP) Multimedia Subsystem (IMS) sessions between the first wireless communication device and two or more other wireless communication devices comprises establishing a first IMS session with a second wireless communication device and, while the first IMS session is ongoing and without placing the first IMS session on hold, establishing a second IMS session with a third wireless communication device. In this manner, simultaneous calling is enabled, which will, for example, allow machines to multitask in comparison to existing non-simultaneous calling.
