Abstract: Systems and methods for multiple mode push-to-x group calls. One example embodiment provides a push-to-X server. The push-to-X server includes a communication interface communicatively coupled to a communication network and an electronic processor. The electronic processor receives, via a unicast uplink channel, a group call request from a first subscriber unit of the communication network. The electronic processor receives, from the first subscriber unit, a push-to-X data stream. The electronic processor receives a unicast channel request from a second subscriber unit of the communication network. In response to receiving the unicast channel request, the electronic processor establishes a unicast channel resource with the second subscriber unit. The electronic processor transmits the push-to-X data stream to the second subscriber unit via the unicast channel resource and transmits the push-to-X data stream to a plurality of subscriber units via a broadcast media bearer channel.

Abstract: A process for operating a communication device to provide location information within status notification messages. The communication device detects a status notification event and responsively retrieves, from a memory, a last known location of the communication device and a timestamp of the last known location. The communication device generates a status notification message including a status code corresponding to a detected status of a user of the communication device, the last known location of the communication device, the timestamp of the last known location, and a unique identifier identifying the status notification message. The status notification message is then transmitted from the communication device to at least one other communication device or a status notification server.

Abstract: A method, Group Application Server, and mobile device are provided that coordinate an operation of multiple mobile devices of a same user in a group call. When the multiple mobile devices join the group call, a first mobile device of the multiple mobile devices determines that it is an active device and provides an indication of such to the Group Application Server. In response to receiving the indication, the Group Application Server identifies a second mobile device, of the multiple mobile devices, that is a non-active device and one or more of modifies subsequent communications with the second mobile device or conveys a behavior modification message to the second mobile device. In another embodiment of the present invention, the first mobile device may indicate that it is the active device directly to the second mobile device and the second mobile device modify its behavior accordingly.

Abstract: A process for establishing a future 2-way authentication between a client application and an application server. In operation, an OIDC server receives a request from the client application to establish a secure connection from the client application. The request includes a certificate generated using a public-private key pair associated with the client application or a user, and authentication credentials associated with the client application or the user. The OIDC server establishes that the authentication credentials are valid, and provisions a cryptographic identifier of the certificate associated with the request to a list of trusted certificates. The OIDC server then provides one or more application servers with access to the list of trusted certificates to enable the application servers to authenticate the client application based on verifying that cryptographic identifier of the certificate presented by the client application is provisioned into the list of trusted certificates.

Abstract: Scheduling resource reservations in a cloud based communications system. One embodiment provides a scheduling server for scheduling resource reservation in a cloud-based communication system. The scheduling server includes an electronic processor configured to monitor events outside of the cloud-based communication system to determine an occurrence of an incident and determine cloud computing resources to be allocated to consuming communication devices assigned to respond to the incident. The electronic processor is also configured to reserve the cloud computing resources such that the cloud computing resources are available to the consuming communication devices for responding to the incident.

Abstract: Methods and apparatus for supporting multiple emergency users in a push-to-talk group. The methods include receiving a first emergency alert from a first user device in the push-to-talk group; receiving a second emergency alert from a second user device in the push-to-talk group; causing the first emergency alert and second emergency alert to be provided to each of the console devices in the push-to-talk group; receiving, from the first user device, a first communication and receiving, from the second user device, a second communication; causing the first communication and the second communication to each of the console devices in the push-to-talk group. The methods further include receiving, from a first console device, a selection of one of the first user device and the first emergency alert; and, in response subsequently selectively routing a third communication from the first user device to the first console device and not to a second console device in the push-to-talk group.

Abstract: A system and process for onboarding client devices to a key management server. In operation, a device generates an asymmetric key pair including a public key and a private key. The device obtains an access token from an identity management server after successfully authenticating with the identity management server. The device transmits a request including the access token and the public key to the key management server to onboard the client device. The device receives a response including encrypted bootstrap information from the key management server. The bootstrap information included in the response is encrypted using the public key of the asymmetric key pair. The device decrypts the encrypted bootstrap information using the private key of the asymmetric key pair to obtain the bootstrap information and then uses the bootstrap information for encrypting communications transmitted to the key management server or for decrypting communications received from the key management server.
