A method and system for providing a fallback solution in a multi-tenant communication system is provided. A cloud-based call processing service receives a voice call initiation request from a first mobile device located at a first communication system. The voice call initiation request includes a request to complete a voice call with a second mobile device located at a second communication system. Resources are allocated at the first communication system and the second communication system. The cloud-based call processing service establishes a call between the first mobile device and the second mobile device. At some point the first communication system determines that it should fallback to single site operation. In fallback mode, call processing functionality is performed at the first communication system for the first mobile device.

Method and system for providing a fallback solution in a multi-tenant communication system

A method and system for completing a call between a first mobile device located at a first communication system and a second mobile device located at a second communication system is provided. A call initiation request including a request to complete a call with the second mobile device is received at a Radio Access Network (RAN) Adaptor (RA) from the first mobile device. The RA determines RAN-specific access parameters for the first mobile device and the second mobile device. The RA sends a call processing call initiation request including the RAN-specific access parameters and call initiation information for the first mobile device and the second mobile device to a cloud-based group call service. The RA establishes resources specific to the RAN in the RA. The resources include first resources at the first communication system and second resources at the second communication system. The call between the first mobile device and the second mobile device is completed using the first resources and the second resources.

Method and system for completing a voice call in a cloud-based communication system using a RAN adapter

A method and system for completing a voice call in a cloud-based communication system is provided. A cloud-based group voice call service receives a group voice call initiation request from a first mobile device located at a first communication system. The group voice call initiation request is a request to complete a group voice call with a second mobile device located at a second communication system. The cloud-based group voice call service allocates resources at the first communication system and the second communication system. The cloud-based group voice call service issues a call grant to the first mobile device located at the first communication system and also issues a call response to the second mobile device located at the second communication system in order to complete the voice call.

Method and system for completing a voice call in a cloud-based communication system

A method and system for processing a Push To Talk (PTT) call at an alternate bearer gateway. The alternate bearer gateway is connected to a Land Mobile Radio (LMR) Core Network and a Broadband Network. The alternate bearer gateway receives a PTT message from either the LMR Core Network or the Broadband Network. The PTT message includes a talkgroup identifier and a message. When the PTT message is received from the LMR Core Network, the alternate bearer network determines at least one Broadband talkgroup member using the talkgroup identifier. The alternate bearer gateway sends the message to the Broadband talkgroup member via the Broadband Network. When the PTT message is received from the Broadband Network, the alternate bearer gateway sends the message to the LMR Core Network.

A method and system for tracking endpoint location information of a first mobile device and a second mobile device that are members of a common talkgroup is provided. The first mobile device is located at a first communication system and the second mobile device is located at a second communication system. A first mobility update request from the first mobile device is received at a cloud-based mobility management service. The first mobility update request includes a request to update first endpoint location information of the first mobile device. The mobility management database is updated with the first endpoint location information. A second mobility update request from the second mobile device is received at the cloud-based mobility management service. The second mobility update request includes a request to update second endpoint location information of the second mobile device. The mobility management database is updated with the second endpoint location information.

Method and system for integrated mobility management in a cloud-based communication system

A mobile communication system () includes an infrastructure () including at least a first base transceiver station () and a plurality of mobile stations (), wherein each of the mobile stations is operable to detect interference by jamming to a signal sent on a downlink channel by the first base transceiver station and, when it determines that such interference exists, to send a notification message to the infrastructure.

Mobile communication system and a mobile station, a base transceiver station and a method for use therein

A method of controlling location information of subscribers () in a wireless, ad-hoc communications network (). The network () comprises a plurality of nodes (), wherein at least portion of said nodes are provided with Home Location Registers (HLRs) () and each of said nodes () has a Visitor Location Register (VLR) (). When an operation of a first node () is to be reconfigured at least a part of records from a first HLR () assigned to said first node () are transferred to at least one of the other nodes () of the network ().
