Talk Group Forming (e.g., Dynamic Regrouping, Talk Group Assignment) Patents (Class 455/519)
  • Patent number: 8259920
    Abstract: A method is disclosed that enables a user of one telecommunications terminal that is engaged in a call to move or “extend” the call to a second telecommunications terminal without notifying any other party on the call of the move. This is particularly useful in many situations. For example, the user might be at work and engaged in a call with a client on the user's wireline desk telephone. If the user needs to leave the office, the user can extend the call to his or her cell phone, while the call is in progress, without notifying the client. This enables the user to leave the office and continue the call on his or her cell phone without having the client ever know that the user is on his or her cell phone and not in the office.

  • Patent number: 8199740
    Abstract: A system and method are provided for reliable, wireless group alerting in a system having a database, switch, wireless network, and a plurality of intelligent mobile receivers, and preferably employing a modified two-way paging based on ReFLEX™ protocol information service (IS) messages and a novel ALOHA command for multicast acknowledgement from mobile receivers. An encrypted message is broadcast to a group address and received by a selected number of the mobile receivers. The network replies to the sender with detailed information about the individual members in the alert group. Each of the mobile receivers in the group then acknowledges the common message back to the system, decrypts the message, displays it to the user, and allows the user to respond. The system employs centralized management to simplify the roles of the mobile users and administrators, minimizing configuration and operational human errors that would otherwise result in confusion or lost messages.

  • Patent number: 8190175
    Abstract: Service node for a telecommunication network and method for determining a group of n user terminals which are closest to a point of interest. First, a search range with an upper limit is set. Then in an iterative manner, a current search cell of the set of cells is determined and the search cell is queried for user data. The user terminals are added to a set of found user terminals, and if the set of found user terminals comprises n or more user terminals, the upper limit of the search range is adjusted to the nth lowest distance. This is repeated until no further possible cell can be determined. The set of criteria can be set and matched with obtained user data to find a closest user terminal having a specific role.

  • Patent number: 8180388
    Abstract: Methods and systems for reducing the latency of instant communication session establishment are presented. According to various preferred embodiments, a RAN, may receive a setup request message via a packet-switched network. The RAN may determine, from a quality of service (QOS) indication contained in the setup request message, that the setup request message is requesting establishment of a instant communication session. The RAN may further determine an intended destination wireless communication device (WCD) for the setup request message. Based on the QOS indication and/or a profile indicating the destination WCD's capabilities, the RAN may pre-allocate resources for the instant communication session in parallel to paging the destination WCD. In this way, the latencies associated with these procedures are overlapped, thus reducing the overall latency of instant communication session establishment.

  • Patent number: 8181226
    Abstract: The invention consists of a first communications device on which an active session is taking place and a second communications device that is not involved in the active session. When a transfer of the session from the first communications device to the second communications device is desired, the handoff is triggered either automatically or manually. The first communications device sends a transfer initiation message to the second communications device. An acknowledgement message is sent from the second communications device to the first communications device. The second communications device, upon receipt of the address information, sends a server transfer message to the session server. The session server, in response to the server transfer message, routes new content to the identified second communications device.
