Embodiment Construction

[0027]Hereinafter, concepts according to embodiments of the present invention will be explained in more detail with reference to the accompanying drawings. The illustrated concept relates to controlling a packet based call between a first party and a second party. In the illustrated embodiment, it is assumed that calls are managed by the IMS infrastructure of the communication network, eg the Multimedia Telephony (MMTel) service provided by IMS. The communication network may in particular be a mobile network implemented based on one or more cellular radio access technologies, such as LTE and / or UTRA (Universal Mobile Telecommunications System Terrestrial Radio Access) and HSPA (High Speed ​​Packet Access). However, it should be understood that the concept can also be implemented in other types of communication networks using other types of access technologies and with other types of IP multimedia systems.

[0028] In the illustrated concept, IMS can be used to set up and mana...

Abstract

A user equipment (50-1) engages in a packet based call between a local party associated with the user equipment (50-1) and a remote party, e.g., associated with a further user equipment (50-2). For this purpose, user equipment (50-1) establishes a control plane session (301) of the call with a node of an Internet Protocol multimedia system (110). Further, the user equipment (50-1) establishes a media session (303) of the call. The media session (303) is managed by the Internet Protocol multimedia system. The user equipment (50-1) determines a local endpoint (60-1) for terminating an additional media session (316) at the local party. The user equipment (50-1) sends a first message (306) of the control plane session (301) to the Internet Protocol multimedia system (110). The first message (306) indicates the local endpoint (60-1). In addition, the first message (306) indicates that management of the additional media session (316) by the Internet Protocol multimedia system (110) is not required. Further, the user equipment (50-1) receives a second message (311) of the control plane session (301) from the Internet Protocol multimedia system (110). The second message indicates (311) a remote endpoint (60-2) for terminating the additional media session (316) at the remote party. The user equipment (50-1) configures the local endpoint (60-1) for transfer of media with the indicated remote endpoint (60-2).

Description

technical field [0001] The invention relates to a method of controlling a group-based call and to a corresponding device. Background technique [0002] Currently, communication networks are evolving from Circuit Switching (CS) networks to Packet Switching (PS) networks, especially Internet Protocol (IP) based networks. For example, LTE (Long Term Evolution) radio access technology specified by 3GPP (3rd Generation Partnership Project) no longer supports CS connection with User Equipment (UE), but only IP-based PS connection. To provide voice support, technologies to support voice communication over PS connections have also been introduced. Examples of such technologies are VoIP (Voice over IP) and more specifically VoLTE (Voice over LTE). [0003] In addition to voice communications, enhanced multimedia services are supported for packet-based calls. For example, mobile networks can be augmented with IMS (IP Multimedia Subsystem) specified in 3GPP Technical Specification (...
