  • Patent number: 9065875
    Abstract: A Push-to-talk over Cellular (PoC) communication session is established between an inviting PoC client and at least one invited PoC client using an IP Multimedia Subsystem network. Establishment involves using a pre-established session procedure to negotiate media parameters between the inviting PoC client and a participating PoC server for the inviting PoC client. At the inviting PoC client, a Talk Burst Control Protocol (TBCP) or Media Burst Control Protocol (MBCP) message is sent directly to its participating PoC server, the TBCP or MBCP message containing the PoC address of the at least one invited PoC client. At the participating PoC Server, in response to receipt of the TBCP or MBCP message, a SIP INVITE message is generated and sent towards a participating PoC server for the at least one invited PoC client.

  • Publication number: 20150120947
    Abstract: The present invention relates to a method for deregistration of a UE from an IMS, the deregistration being initiated from and performed by a P-CSCF node. The present invention also relates to a P-CSCF node comprising a processor and a memory storing a computer program, which when run in the processor, causes the P-CSCF node to perform the method. The method includes monitoring at least one parameter associated with UE behaviour in the IMS and triggering generation of a message in response to that the monitored parameter meets predefined criteria. The message is inserted in a SIP header message and sent to the S-CSCF node which forwards it to the HSS. The P-CSCF node then receives an acknowledgement from the S-CSCF node that the UE has been deregistered from the HSS and terminates the UE session with the IMS.

  • Publication number: 20140185490
    Abstract: A method and apparatus for handling a communication session in a communications network. An Application Function node receives a request to register a user terminal in the communication network. The Application Function identifies an Access Point used by the terminal to register with the network, and send a request message to a Policy and Charging Register Function (PCRF). The request message includes an Access Point Name identifying an Access Point used by the user terminal. The AF receives a response message from the PCRF, including an indicator indicating whether the Access Point is an Emergency-Access Point. The AF subsequently receives a message from the user terminal that identifies a non-emergency terminating node. If the indicator indicates that the Access Point is not an Emergency-Access Point, the AF allows the communication session. If the indicator indicates that the Access Point is an Emergency-Access Point, then the AF rejects the communication session.

  • Patent number: 8711733
    Abstract: A method and apparatus for indicating to a node in an IMS network a transfer between two endpoints. A node in a first network determines that a communication session is to be transferred from a first endpoint to a second endpoint. The node includes an indication of at least one of the endpoints, and an explicit communication transfer indicator, in a message. The message is then sent towards the node in the IMS network. This allows the node in the IMS network to determine that a transfer has taken place and, if necessary, take further action.

  • Patent number: 8447340
    Abstract: A terminal (such as that belonging to or carried by an emergency first responder, for example) participates in a push to talk multicast group in either of two modes or levels. In a first mode or first level of participation, the terminal can join a multicast address for the push to talk multicast group as a passive recipient of transmissions and can thereby listen to the multicast address. In a second mode or second level of participation, the terminal becomes an active participant in the push to talk session. As an active participant in the push to talk session, the terminal can, e.g., receive sender identification (e.g., identification of other participants who may be talking in the push to talk multicast group) and send media bursts to the multicast group.
