Candidate providers progress through steps of a network registration process by providing input data at the various steps. The network system provides communications to request the input data and facilitate the candidate providers' progress. The network system can use a machine learning model to predict particular types of communications and communication channels (e.g., online messages, phone calls, physical mail, etc.) that are likely to be well-received by candidate providers. Thus, the network system is able to increase the expected number of candidate providers that successfully register to provide services to other users of the network system.

Abstract: A method for extending the connection time of talkgroup radios in a talkgroup conversation based on historical talkgroup statistics is provided. A talkgroup conversation request intended for a talkgroup is received from a first mobile unit. A group call grant message is sent to radios that are members of the talkgroup. The group call grant message initiates the talkgroup conversation with a first talkgroup call and includes an extended connection time value. Once it is determined that the first talkgroup call has ended, all radios that are members of the talkgroup are kept in a connected state. An extended connection timer utilizing the extended connection time value is started. Upon expiration of the extended connection timer, all radios that are members of the talkgroup are set to an idle state.

Abstract: A gain control circuit in a wireless distribution system (WDS) is provided. The gain control circuit generates a combined digital communications signal based on a number of received radio frequency (RF) communications signals. The combined digital communications signal has a digital amplitude(s) representing a summed analog power level(s) of the RF communications signals in a predefined number of binary bits. When the summed analog power level(s) exceeds a maximum analog power level represented by the digital amplitude(s) in the predefined number of binary bits, the gain control circuit determines a selected RF communications signal(s) causing the summed analog power level to exceed the maximum analog power level and attenuates the selected RF communications signal(s) to reduce the summed analog power level to below the maximum analog power level. As such, it is possible to achieve a calculated balance between performance, complexity, and cost in the gain control circuit.
