摘要:
A security method (100) in a radio access network can include monitoring (102) (by either a base station controller or a mobile radio) for one or more abnormalities among CPU utilization, memory storage, memory read-write, malicious incoming or outgoing messages, and virus file names, notifying (104) of a specific abnormality detected, and receiving (108) access, conditional access or limited access based on the specific abnormality detected. The method can further include receiving updates (112) used for monitoring the abnormalities. The method can further include the optional step (106) of issuing a notification from a mobile radio to a base station controller if the specific abnormality is detected and suspending (110) one or more services based on the specific abnormality detected. The method can further include receiving (114) at the mobile radio an over the air programming instruction to suspend a specific service and alerting the mobile radio.

Various embodiments are described for establishing a group call session serially. After receiving a serial group call request from a remote unit (101), fixed network equipment (FNE) (201) selects a first subset of members (260) from the targeted group (250) of units and signals those members to join the group call session. Various techniques for selecting the first subset may be employed depending on what system benefits are desired. A second subset of members (270) from the targeted group of units is also selected and signaled to join the session. This second subset may be used to invite additional units in order to achieve a maximum number of group participants. Alternatively, the second subset may be used to invite a different unit (or units) to participate. This can be triggered by a user request to invite another subset to the group session, as could occur when the user is not able to resolve the particular matter at-hand with the group members of the first subset.
摘要:
A communication system is provided that comprises a Radio Frequency Identification (RFID) network coupled to a service provider network. An RFID reader of the RFID network detects an RFID tag associated with a mobile station when the mobile station is present in, or proximate to, a controlled area. The RFID network routes information associated with the RFID tag to the service provider network and, based on the information received from the RFID network, the service provider network alters a behavior of the mobile station when the mobile station is entering, exiting, or present in the controlled area.

A method of forecasting unscheduled component demand for a plurality of components in a fleet of assemblies includes establishing a set of models to be used for forecasting unscheduled component demand, selecting a best model for each component, and determining a date at which a cumulative probability of unscheduled component demand reaches a predetermined threshold.
摘要:
A method (300) and a network device (112) for providing a service in a network (100) are disclosed. The network includes an originator device, a network device and one or more target devices. The method includes receiving (304) a request from the originator device for initiating the service with the one or more target devices. Further, the method includes identifying (306) one or more specific initial ranging codes associated with each of the one or more target devices. Furthermore, the method includes transmitting (308) a paging message to each of the one or more target devices in response to the request made by the originator device. Moreover, the method includes transmitting (310) a service signal to the originator device based on response of the one or more target devices within a predefined time interval.
摘要:
A plurality of wireless addresses to be transmitted using a shared message and at least one item of informational content are provided (101 and 102). At least some of the plurality of wireless address are then arranged (103) into an order that represents the at least one item of informational content. Upon transmitting (104) a shared message that contains this content, a receiving platform can, in turn, decode (302) (and hence recover) the at least one item of informational content as a function, at least in part, of that aforementioned particular order.
摘要:
A system and method for reducing the transmission delay of messages sent through a network from a source mobile unit (112) to a destination mobile unit (114). Portions of a data message are received (202). The portions of the data message are decoded (204) and a type of the data message is determined from the decoded portions. Before the entire data message has been received, processing and service actions are performed as a result of receiving the data message (206) based at least in part upon the type of the data message.
摘要:
A call management system (136) and method that allows a first wireless voice call to be temporarily disconnected at a mobile device (130) while another communications session is performed from the same device (130). During a first voice call between a wireless communications device (130) and a second party, a network hold command is received. The second party is then placed on hold and wireless communications resources for the first wireless call are released. The wireless communications device (130) is subsequently reconnected to the second party. The reconnection includes removing the second party from hold and connecting the second party to the second voice call. A unit identifier (240) identifying the wireless communications device (130) is stored in an infrastructure database (114) along with an identifier of the first voice call to facilitate reconnection. Prior to reconnection, a wireless data communications session can be performed.
摘要:
A method and computer program for initiating a message to a radio access network include steps of: (404) detecting a request to transmit a probe message from a transmitter over an access channel to a radio access network; (406) calculating a transmit power for the probe message; (408) checking a condition that may result in failure to receive the probe message over the access channel by the radio access network; and (410) when the condition is determined to be true, then (412) reducing a message length of the probe message to generate a shorter probe message; (414) recalculating the transmit power to send the shorter probe message; and (416) transmitting the shorter probe message over the access channel at the recalculated transmit power.
摘要:
To address the need for a dispatch mobile (303, 305, 307) to more quickly make a call, in the preferred embodiment of the present invention those remote units operating in a dispatch mode (303, 305, 307) will receive a first slot cycle, while those remote units not operating in a dispatch mode (302, 304, 306, 308) will receive a second slot cycle. The second slot cycle is greater than the first slot cycle, so that those remote units operating in dispatch mode (303, 305, 307) will “wake up” during the slot cycle normally utilized for interconnect calls. Because shorter slot cycles are utilized for remote units operating in dispatch mode (303, 305, 307), the time it takes to make a dispatch call is greatly reduced. Additionally the minimum slot cycle duration typically used for standard calls remains unchanged, greatly conserving battery life.
