Disclosed are systems, apparatus, and methods for propagating data changes in a distributed computing system from source components to target components. In accordance with various embodiments, one or more producer components of a data-conveyor system may detect changes to data records in one or more source components, and store backlog entries responsive to detecting the changes, wherein these backlog entries do not include contents of the data record. One or more consumer components of the data-conveyor system may retrieve updated data of changed data records based on the backlog entries and provide the updated data to one or more target component(s).

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments herein achieve a UE for managing a user plane operation in a wireless communication system. The UE includes a user plane management unit coupled to a memory and a processor. The user plane management unit is configured to receive a signaling message from a gNodeB. Further, the user plane management unit is configured to determine whether the signaling message includes control information comprising one of a PDCP re-establish indication and a security key change indication. Further, the user plane management unit is configured to perform the at least one operation for at least one data radio bearer based on the determination.

Methods for providing contextual information about communication devices and/or services. Profile information indicating a user's communication devices and/or services is stored. When profile information or a message log is displayed, the user may identify a communication device and/or service. A query inquires whether the user would like contextual information. The contextual information may be obtained from a gateway in a data network or a telecommunications manager in a telecommunication network. The contextual information is displayed. Profile information about a user's communicating partner may be stored. When the user makes an effort to communicate with the partner, a check may be made of the partner's profile information for a preferred communication device and/or service. If the user does not have a communication device and/or service corresponding to that of the communicating partner, a query may inquire whether the user would like contextual information. If so, the contextual information is presented.

A method for passive enrollment and identification of one or more speakers in an audio file includes automatically converting audio data to a format suitable for biometric processing, separating different channels present in the converted audio data separating speakers in the converted audio data, generating audio files specific to individual speakers in the converted audio data, iteratively grouping the audio files of individual speakers according to a predetermined matching criteria, creating biometric voice prints from the groups of audio files, and authenticating speakers in the biometric voice prints by comparing the biometric voice prints to entries in a biometric voice print database.

Systems and methods provide a resident of a controlled-environment facility with a visitation service that include messaging capabilities, where the message are managed on behalf of the resident based on the visitation sessions in which the resident participates. In one scenario, the resident issues an initial visitation request for a visitation session with a particular non-resident. In response to the non-resident not accepting this initial visitation request, the resident is allowed to record and store a message, such as a voice message or video message, for retrieval and playback by the non-resident. At a later time, the resident issues a second visitation request for a visitation session with the same non-resident. The non-resident accepts the second request and the requested visitation session between the non-resident and the resident is conducted. In response to the visitation session being conducted, the stored message may be marked for deletion.

A method for using a system which enables a party to provide an in-call message to another party in an ongoing call includes receiving a first signal indicating that a first party in a call is inactive. The method further includes indicating to a second party in the call that the first party in the call is inactive. The method further includes receiving a recorded message from the second party in the call. The method further includes receiving a second signal indicating that the first party in the call is active. The method further includes providing, in response to receiving the second signal, the recorded message to the first party.
