  • Patent number: 8195214
    Abstract: A floor can be fairly acquired in a PoC communication. In the PoC server which controls a floor in a PoC communication, a floor is put in an idle state in a PoC communication after a session establishing process required in the PoC communication. The information about the floor idle state is notified to terminals TA and TC which perform the PoC communication. When the PoC communication is initiated, the idle state of the floor is simultaneously noticed to both calling and called users, thereby realizing fair acquisition of a floor.

  • Patent number: 7853278
    Abstract: Time required before PoC communication starts, in the case where a communication channel on the destination side has not been established, is shortened, and convenience of users is enhanced. A request for establishing a communication channel used for PoC communication is sent from a terminal TA. Immediately after receiving this request, call processing for establishing a communication channel to a terminal TC other than the terminal TA is started. In parallel with this call processing, processing after sending a response to the request is performed. Thereby, response to a communication channel connection request, SIP Registration processing and Invitation processing on the originating side and the processing on the destination side are performed in parallel, so that connection time can be shortened, and PoC communication can be started early.

  • Patent number: 7774026
    Abstract: Such regulation control that the processing load on the network side is low and, furthermore, particular services are not regulated is realized. A regulation table is stored in a mobile communication terminal 1. When regulation level information is indicated by a maintenance device 4, transmission regulation control for regulating transmission operation is performed based on the content of the regulation table. In this case, it is possible to regulate particular services which use packet communication, while it is also possible to avoid regulating particular services. Since the maintenance device 4 only indicates regulation level information indicating which part in the regulation table should be used and does not indicate the content of regulation, the processing load on the network side is low.

  • Patent number: 7711380
    Abstract: Subject to user's setting in PoC group communication, the user address of that user is set to non notification against other users. In case of starting PoC group communication, a PoC subscriber selects non notification subjects and transmits a PoC session commencement request. At that time, the caller sets his own address and/or address/addresses of all or a part of users to non notification. On a user designated as a non notification subject due to the caller's setting, PoC terminal apparatuses in receipt of a PoC session commencement request or PoC communication service controlling apparatuses undergo non notification setting processing. On a called party not selected as non notification subject users, if he/she sets his/her own user address to non notification in advance, likewise non notification processing is implemented. Even after a PoC session is established, each user can set his/her own user address to non notification and non notification service complying with user's intention is providable.

  • Publication number: 20070019572
    Abstract: Radio resources for maintaining a communication channel can be used efficiently by synchronously controlling a communication channel establishment process and a Registration process by SIP. If a SIP server 1A obtains a request message by SIP from a calling terminal device in a state in which a communication channel has not been established and a state in which a SIP transaction has not been established (step SO), a short message for prompting communication channel establishment and a Registration process is sent to a called terminal device 2B (steps S8 to S11). Then, a process for establishing a communication channel is performed (steps S17 and S18), and a process for establishing a SIP transaction is performed after the communication channel establishment process is performed (steps S19 and S20).
