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.

A Mutual Aid QoS Function (MAQF) performs a method for determining policy for user equipment (UE) providing mutual aid in a mutual aid enterprise operating area of a Long Term Evolution (LTE) system. The method includes: receiving an indication that a UE is assigned to provide mutual aid in a mutual aid enterprise operating area, wherein the UE has a home enterprise operating area that is different than the mutual aid enterprise operating area; detecting that the UE has entered the mutual aid enterprise operating area; selecting a set of mutual aid policy rules for the UE while the UE is providing mutual aid in the mutual aid enterprise operating area.

A method and apparatus for enabling a group communications follow mode at a first group communications (GC) user equipment (UE) device. A GC server receives a request from a first client UE device to follow a second Client UE device, and responsively: affiliates the first client UE device with a same one or more talk groups with which the second client UE device is currently affiliated, monitors for talk group affiliation and disaffiliation requests from the second client UE device and automatically affiliates or disaffiliates both the first client UE device and the second client UE device from a first particular talk group in accordance with a corresponding affiliation or disaffiliation instruction received from the second client UE device.

A method for bearer reservation, maintenance, and use in a communication system is performed by an intermediary function (IF) in the enterprise network. The IF processes a user plane reservation request for a flow of user plane data from a sourcing device, and determines a set of bearers to transport the flow of user plane data. The IF requests from at least one access network the determined set of bearers, and receives from the at least one access network an allocated set of bearers, wherein the allocated set of bearers comprises one or more bearers. The IF receives the flow of user plane data from the sourcing device. The IF receives an indication that at least one of the bearers in the allocated set of bearers is unavailable, and prevents at least a portion of the flow of user plane data from being transmitted over the default bearer.
摘要:
An abnormal termination of a dedicated bearer (e.g., a lost bearer) (134) or a change in bearer characteristics that renders the dedicated bearer unusable of a mobile device (114) can be detected. The lost bearer (128) is a bearer that is not a default bearer (132) within a communication network that includes one or more lost communication flows (135). At least one radio access network (RAN) capable of communicating with the mobile device (114) can be determined, where the at least one RAN is not one used for the dedicated bearer (134) that was abnormally terminated. At least one alternative bearer (150) can be detected or established at the at least one RAN. Each lost communication flow (138) can be automatically and dynamically routed to the at least one alternative bearer (150). The routing of the lost communication flows (138) can occur without interrupting communications.
摘要:
A PTT bridging gateway between a first PTT system and a second disparate PTT system: receives an invitation to a first client to join a first group call for a first group comprising multiple member clients on the first PTT system, wherein the first client is one of the member clients of the first group; determines that the first client is mapped to a second group comprising multiple member clients on the second PTT system; and initiates a second group call to the multiple member clients on the second PTT system.
摘要:
A wireless communication device acquires membership in a predefined group, joins an ad hoc network associated with the predefined group, and joins and participates in a first session established through an infrastructure device for distributing media to the predefined group. If the wireless communication device is a duplicator node for the ad hoc network, then it receives the media from the infrastructure device and distributes the media other nodes of the ad hoc network, otherwise it receives the media from the duplicator node. The infrastructure device identifies the duplicator node for each ad hoc network associated with the predefined group and each member of the predefined group that is not a node of any of the ad hoc networks and distributes the media only to these members of the predefined group.

Systems and methods are provided for controlling use of uplink random access channels (RACHs) based on multi-dimensional subscriber classification. These systems and methods are useful in cellular communication networks that implement, for example, a public safety cellular system.

An apparatus and method for dynamic vocoder assignment in a communication system that supports multiple vocoders includes a first step (30) of detecting changing a call environment in a group call. A next step (32) includes dynamically determining a list of vocoders in order of system preference in response to the change in call environment. A next step (34) includes communicating the ordered list of vocoders in an existing floor control message to the participants in the call. A next step (36) includes selecting, by at least the current transmitting participant, the first vocoder that it supports from the list of preferred vocoders, for use in that participant's next transmission in the group session.
