The present invention can save NCH channel resource and increase running quality of group call communication service in GSM group communication system.
While participating in a group call on a first wireless communication resource (114), senior members (104-107) of a communication group (108) can initiate a semi-private call.
A method and apparatus is provided allowing a mobile subscriber (30) disconnected from a group call to re-enter the group call.
Disclosed is an apparatus for monitoring a multisession including one-to-one calls and group calls at a same time in a wireless communication system performing group communication.
Executive members can participate in the executive call, the semi-private call, and the group call, whereas senior members can participate in the semi-private call and the group call.
The group communication comprises the first communication.
The group communication is directed to a group.
The charging information collection unit examines a group communications message received from the first group communications network element or the second group communications network elements.
When the user has created a communication group, a group communication server (10) processes the group further as any other group.
The group communication also comprises an identifier that identifies the first communication of the group communication as originating from the first user equipment.
Furthermore, the invention provides a system to achieve cluster communication service, cluster communication method and cluster communication system.
The wireless communication device may have one of a cluster communication gateway role and a cluster internal communication role.
The cluster internal communication role comprises maintaining at least a peer-to-peer communication link to a specific device having the cluster communication gateway role.
The users of the group communication would benefit especially from summarized group information.
The invention discloses a solution for establishing by a handshake procedure a group temporal key for group communication.
A down frame generation means (11) generates down frames for group communication by providing time slots for group communication.
Embodiments are directed selectively mixing media at an application server arbitrating a group communication session for a communication group.
The IM clients can perform sending or receiving group communication information with designated recipients, and can identify confidentiality of group communication information.
A flexible group communication control is performed efficiently.
Group communications methods and apparatus are described.
The QR code encodes the information needed to initiate and/or join a group communication session maintained by a group communication server.
The present invention in general relates to the field of communication.
The present invention is applicable to session based group communication, where session is established first before the group communication starts.
Also the service function entity for use in group communication and the gateway for use in group communication.
In an embodiment, an access terminal (AT) obtains media intended for transmission to a communication group during a group communication session (GCS).
