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.

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: Techniques for dynamically changing the interval to receive data from an evolved multimedia broadcast multicast service bearer are provided. A wireless device may monitor a first bearer channel, the first bearer channel sending control messages at a first interval. An indication to monitor a second bearer channel may be received, the second bearer channel sending control messages at a second interval. The mobile device may monitor the second bearer channel at the second interval.

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 and console are provided that create an explicit talk group list for a user device, the explicit talk group list is created by the user device and includes a plurality of first talk groups. A privileged user device, such as a console, creates an implicit talk group list for the user device. The implicit talk group list includes a plurality of second talk groups. The explicit talk group is combined with the implicit talk group list to form a scan list. If the number of talk groups in the scan list exceeds a predetermined threshold, enough talk groups are removed from the scan list until the number of talk groups in the talk group equals the predetermined threshold.

Abstract: A method and console are provided that assign a user device access to a remote service, such as a talk group. The user device is provided access to communications history associated with the remote service. At some point access to the remote service for the user device is revoked, but access to the communications history associated with the remote service is not revoked at this time. At a later time, access to the communications history associated with the remote service from the user device is revoked.

Abstract: A method is provided that sets up a Push-To-Talk (PTT) call. A first group is given a first value of an attribute, such as the priority of the PTT call or the state of the PTT call. A second group is given a second value of the attribute, such that the second value of the attribute is different from the first value of the attribute.

Abstract: A method to provide ambient listening on target devices is shown. The ambience listening can be initiated by the listener or by the target device. When a console initiates an Ambience Listening (AL) call regarding a target and the target is logged into more than one device, the PTT server presents the console with a list of all concurrent devices of that user. The console is presented with additional information regarding the target, such as the location, role selected by the user on each device, and the user's operational status on each device. The operational status includes, for example, an emergency state. This enables the console to setup one or more ambience listening session with one or more appropriate devices.

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.
