Patent number: 8315190Abstract: A method and apparatus for interworking between push-to-talk over cellular (PoC) systems and instant messaging (IM) systems is provided. An interworking entity that behaves like a PoC client to a PoC server and as an IM client to the IM server is provided. The interworking entity may be implemented as part of the PoC server or the IM server. The interworking entity listens to talk bursts from the PoC server and when it receives a talk burst the interworking entity sends the message to the IM client via the IM server. In an embodiment, the interworking entity listens to talk bursts or audio clips from the IM server and when it receives them, stores them in a temporary storage memory and converts them to a streaming format. The interworking entity then requests the floor from the PoC server, and, once the floor is granted, streams the stored audio clip or talk burst to the PoC server. The PoC server then distributes the clips to the PoC clients.Type: GrantFiled: January 26, 2006Date of Patent: November 20, 2012Assignee: QUALCOMM IncorporatedInventors: Roozbeh Atarius, Ramachandran Subramanian

Patent number: 8289924Abstract: A technique is disclosed, according to which it is possible to efficiently use network resources, to reduce the burden on a control device, and to control the communication between radio terminals by the control device when a transmitting side radio terminal and a receiving side radio terminal are connected to the same radio relay device. According to this technique, when a transmitting side UE1 and a receiving side UE2 are connected to the same E-Node B 103, the transmitting side UE1 divides a transmission packet addressed to UE2 into a first packet to be transmitted via a route not passing through ACGW 105 and a second packet to be transmitted via a route passing through ACGW 105, and the packets are transmitted to E-Node B 103. E-Node B 103 transmits the first packet to UE2 and also transmits the second packet to ACGW 105.Type: GrantFiled: August 24, 2007Date of Patent: October 16, 2012Assignee: Panasonic CorporationInventors: Tetsuro Morimoto, Takashi Aramaki, Hiroyuki Ehara
