摘要:
A system and method that allows a mobile device to register for IMS services while the mobile device is roaming in a visited telecommunications network is disclosed. The system receives a request for multiple IMS services from a mobile device while the mobile device is roaming in a foreign network. The system uses an identifier of the foreign network and an associated RAT type to query a policy table containing a list of whitelisted IMS services for the foreign network and associated RAT type. The system processes the requested IMS registrations for services that are whitelisted and does not process requested IMS registrations for services that are not on the whitelist.

A messaging device facilitates delivery of messages to recipients based on availability and preferences associated with recipients. In some embodiments, messages are composed by a user via a touchscreen display. Icons representing potential message recipients are displayed, and the user may deliver a message to a recipient by associating the message with the icon that represents the desired recipient. The facility uses availability information—which reflects recipients' availability and willingness to communicate—and system- and recipient-defined preferences to determine the best method(s) of delivery for a message and other features of message delivery. Recipients' availability and preferences may be displayed to users on an interface. Users may make decisions regarding delivery method, timing, and other details of message delivery based on the displayed availability and preference information.
摘要:
A transmitter and method is disclosed for multiband wireless communication. Frequency bands and/or transmission formats are identified as available within a range for wireless communication. Signal quality metrics for each frequency band are evaluated by a receiver to identify qualified frequency bands. The qualified frequency bands can be ranked according to one or more signal quality metrics, where the list of qualified bands can be communicated to a transmitter. The transmitter is arranged to evaluate the list of qualified bands and select a communication method based on the available frequency bands and a selected communication optimization scenario. Multiple frequency bands and communication methods can be utilized by the transmitter such that a combination of licensed, unlicensed, semilicensed, and overlapped frequency bands can be simultaneously used for communication. The receiver continually monitors communications and can report link performance to the transmitter for adaptive control of the selected communication methods.

A touch screen testing platform may be used to perform repeatable testing of a touch screen enabled device using a robotic device tester and a controller. The platform may use various types of conductive tips that engage the touch screen, thereby simulating human behavior. The platform may perform multi-touch operations by employing multiple tips that can engage the touch screen simultaneously. The tips activate a touch screen from at least a trace of conductive coating located on nonconductive components of the robotic device tester.

User equipment communicating with a telecommunications network may be configured to selectively initiate a communication session with another device via a first access network of a first type. During a pre-establishment phase, the user equipment may measure the first access network to provide a first measurement. In response to the first measurement corresponding to a first service-interruption condition, the user equipment may cancel the communication session, tune a radio of the user equipment to communicate with a second access network of a second, different type, and re-initiate the communication session with the other device via the second access network. The user equipment may, after the canceling, receive a retry invitation to the communication session via the second access network, tune the radio thereto, and re-initiate the communication session with the other device via the second access network.
摘要:
This disclosure is directed at least partly to routing calls and/or other communications from a Mobile Virtual Network Operator (MVNO) that uses a Mobile Network Operator (MNO) as a transit network. The MVNOs may desire to use the MNO's network as a transit network to complete or terminate calls from users who may be roaming and/or are on other access networks such as Wi-Fi. The MNO may implement logic to determine whether to allow the MNO's network to be used as a transit network based at least in part on conditions such as one or more of agreements with an MVNO, business considerations, and/or other considerations (e.g., network bandwidth, etc.). The logic may enforce the rules by selectively allowing some communications and denying other communications.

Systems, apparatus, methods, and manufactures for performing link adaptation in a communications system are described. The methods may employ an error rate table that has a channel condition value dimension and a transmission parameter dimension. The elements of the error rate table include expected error rates for data transmitted at various channel conditions according to various transmission parameters. Also, the various transmission parameters may each be associated with a data transmission rate. For a given channel condition value, the methods may determine expected throughputs for each of the transmission parameters according to the associated expected error rates and data transmission rates. A transmission parameter may be selected according to the expected throughputs.
摘要:
Techniques are described herein for receiving, by node of a telecommunication service provider, a network data packet from one of an application client of a telecommunication device and an application server. The node may then retrieve application information from a header of the network data packet and apply the application information to adapt radio delivery. Alternatively or additionally, the node may then insert radio information into the header of the network data packet in place of the application information. After performing the inserting or the retrieving, the node may transmit the network data packet to the other of the application client and the application server.
摘要:
Systems and methods for the management of communications related to telecommunications-based devices are provided. Telecommunications-based devices initiate requests to gateway computing devices corresponding to a radio communication network to establish data communications. The gateway computing device accepts the communication request and specifies an ordered preference of one or more communication protocols that will be used telecommunications-based devices accessing the wireless communication network. The telecommunications-based device processes the acceptance and selects a communication protocol from the ordered preference provided by the gateway computing device.
摘要:
A facility for selecting a location determination technique from multiple available location determination techniques in order to determine the location of a mobile device in a cost or resource efficient manner. In order to select the location determination technique, the facility may consider various criteria such as the cost of employing the techniques, quality of service (QoS) criteria, the capabilities and/or resources of given mobile devices and/or networks, and/or the like. To select the location determination technique, the facility may rank the multiple location determination techniques according to weighted criteria and select the location determination technique according to the ranking. The criteria may be weighted according to the relative importance of each criterion to a requesting location-based service.
