摘要:
Critical resource data (192) required for a group call can be identified. Controlling (115) and secondary (155) PTT communications systems can communicate using an expanded network-to-network interface (NNI) (140). Allocation of identified critical resources (150) can be requested (145) for the group call from the secondary PTT communications system (155). In response to a successful allocation of the requested critical resources by the secondary PTT communications system, the group call can be authorized by the controlling PTT communications system (115). The allocated critical resources of the secondary PTT communications system (155) can be used to establish the group call.

摘要:
A centralized quality of service (QoS) entity having a processing device performs a method for managing QoS settings for group communications. The method includes: determining a plurality of active participants of a group communication session; and determining, for each active participant, an individual QoS setting, including a first individual QoS setting for a first active participant. The method further includes modifying the first individual QoS setting based on the individual QoS setting for at least one other active participant, wherein the modified first individual QoS setting is applied to a session leg used by the first active participant during the group communication session. The active participants of the group communication session can be on the same or heterogeneous wireless networks.
摘要:
A method for rapid peer-to-peer link establishment among a set of mobile devices includes operating a first second device, advertising system attributes in a wireless beacon by the second device, receiving the system attributes from the wireless beacon at the first device, comparing the system attributes to a service needed by the first device, and, if the second device is compatible based on the comparing, establishing a wireless link by the first device to the second device. A system and wireless device for rapid peer-to-peer link establishment among a set of mobile devices are also described.
摘要:
A hosted inter-radio frequency subsystem interface (HIF) maintains a list of affiliated radio frequency subsystems (RFSSs), the list identifies at least one serving RFSS. An affiliation request is transmitted from the HIF to the home RFSS, which is a home RFSS of the group. The HIF receives from the serving RFSS a request to initiate an inter-RFSS group call to the group using HIF addressing. The HIF transmits a request to the home RFSS to initiate the inter-RFSS group call using serving RFSS addressing. A data packet from the home RFSS or the serving RFSS is received at the HIF. Upon receipt, the HIF transmits a copy of the data packet to the serving RFSS if the data packet was received from the home RFSS; otherwise, the HIF transmits a copy of the data packet to the home RFSS if the data packet was received from the serving RFSS.
摘要:
An apparatus and method for dynamic group prioritization in a communication network includes a first step (400) of defining a dynamic list of group participants by an application, such as a dispatch function. A next step (402) includes sending a request to a Group Management Function, wherein the request includes a requested group priority and the list of group participants. A next step (404) includes allocating a unique identifier to the group and assigning a group priority to the group. A next step (406) includes notifying the application, group participants, and network of the unique identifier and the network of the assigned group priority. The assigned priority of the group and its flows can be dynamically altered in real-time while the group is active.

摘要:
A method and device enable establishing an inter-radio frequency subsystem interface (ISSI) unit-to-unit call between a calling unit of a calling home radio frequency subsystem (RFSS), and a called unit of a called home RFSS, through a hosted ISSI function (HIF). The method includes processing, at the HIF, a first invite message received from the calling home RFSS, wherein the first invite message includes a first request uniform resource identifier (URI) that designates an alias system unit identification (SU-ID). In response to the first invite message, transmitting, from the HIF to the called home RFSS, a second invite message, including a second request URI that designates a real SU-ID, wherein the HIF acts as the calling home RFSS. The unit-to-unit call is thus established between the calling unit and the called unit through the calling home RFSS, the HIF, and the called home RFSS.
