According to one aspect, a method includes obtaining, at a client included in a push-to-talk (PTT) system, a plurality of talk bursts including at least a first talk burst and a second talk burst, the first talk burst being associated with a first source included in the PTT system, the second talk burst being associated with a second source included in the PTT system, wherein the plurality of talk bursts are obtained at approximately a first time. The method also includes identifying the first source as a source of interest and determining, after identifying the first source as the source of interest, an identity of the first source. Finally, the method includes processing the first talk burst as having a priority over the second talk burst.

System and method for identifying talk burst sources

A method and apparatus to provide access to video streams associated with communication channels in a communication network are described. The method may comprise monitoring selection of a communication channel by a user of a mobile communication device, identifying at least one video feed associated with the selected channel, and providing access to the mobile communication device to the selected at least one video feed. Providing access may comprise associating the selected video stream with the mobile communication device.

Access to video streams on mobile communication devices

A method is provided in one example implementation and the method includes interacting, via a first communication resource manager located in a first domain, with a second communication resource manager located in a second domain. The method further includes determining whether to establish a link for multicasting between users in the first domain and users in the second domain, and the link between the domains is established based on presence data of at least one user in the first domain and at least one user in the second domain.

System and method for providing presence based trunking in a network environment

In an example embodiment, a method is provided that accesses a list of communication preferences. The list identifies a communication paradigm and a different communication paradigm. Link quality information associated with the communication paradigm also is accessed. Based on the link quality information, communication may be switched from the communication paradigm to the different communication paradigm.
