Abstract: A multidrop network system includes N network devices. The N network devices include a master device and multiple slave devices, and each network device has an identification code as its own identification in the multidrop network system. The N network devices have N identification codes and obtain transmission opportunities in turn according to the N identification codes in each round of data transmission. Each network device performs a count operation to generate a current count value, and when the identification code of a network device is the same as the current count value, this network device obtains a transmission opportunity. After a device obtains the transmission opportunity, it determines whether a cut-in signal from another network device is observed in a front duration of a predetermined time slot, and then determines whether to abandon/defer the right to start transmitting in the remaining duration of the predetermined time slot.

Abstract: Apparatuses, systems, and methods for emergency communications (e.g., voice calls and/or SMS messages) for UE's without cellular coverage (e.g., in non-cellular coverage).

Abstract: A system and method for pausing communications from a transmitting radio for a certain period of time in order to allow transmission of other messages. When a first radio determines that a message needs to be transmitted either to a second radio or the transmitting radio, the first radio determines whether there are any available forward channels to transmit the call. If no forward channel is available, the first radio determines a period of time required to transmit the message and sends, on a reverse channel, a “request to pause” signal to the transmitting radio identifying that period of time. Upon receiving the “request to pause” signal, the transmitting radio ceases transmission on the forward channel for the specified period of time, during which time the first radio transmits the message.

Abstract: A wireless telephone and messaging system provides Secure Immediate Wireless Access (SIWA) to wireless telephones onto existing wireless networks. The SIWA protocol uses existing wireless network messaging to exchange information between wireless devices and a network server, referred to herein as an Intelligent Service Manager (ISM).

The ISM can also deny access to the wireless network from unauthorized wireless devices.

Abstract: A method, system, and apparatus enables lower priority (e.g., access response) messages to be transmitted instead of higher priority (e.g., paging) messages when the lower priority messages become too backlogged in an environment in which the two types of messages share a given capacity. In other words, when an overload situation is detected, the shared capacity is regulated by ensuring that the lower priority messages have at least some bandwidth. For example, if (i) the lower priority messages reach a predetermined number or (ii) a particular lower priority message has been waiting a predetermined period of time, then at least a portion of the higher priority messages are diverted (e.g., delayed or deleted). In one embodiment, the higher priority messages that are initially diverted are a lowest priority subset of the higher priority messages. In another embodiment, a highest priority subset of the lower priority messages are transmitted first as capacity is made available.

The access request may also be serviced based on a current usage status of the wireless telecommunications network. Mobile stations with higher priorities may receive a preference for access to the wireless network's resources. Mobile stations with lower priorities may be disconnected from the wireless network to accommodate a higher priority mobile station.

Abstract: An emergency routing number is assigned to each switch in a wireless network. When a switch of the wireless network routes an emergency call to a Public Service Answering Point (PSAP), the switch sends the emergency routing number as the calling party number and provides the PSAP with the identifier of the mobile station. If the emergency call drops, the PSAP performs a call back using the emergency routing number as the called party number. The switch that routed the emergency call from the mobile station to the PSAP receives the call back. The PSAP also sends the identifier of the mobile station to the switch. When a switch receives its emergency routing number as the called party number, the switch recognizes an emergency call back situation and pages the mobile station identified by the mobile station identifier received in association with the emergency routing number. The mobile station is then reconnected with the PSAP.
