Method and system for access gateway selection

Abstract: Methods and systems are defined that support, in a radio access network, measuring the latency between the radio access network and each respective access gateway of a plurality of access gateways. From these measurements, a list of access gateways, rank ordered from lowest to highest latency, is created. If the radio access network receives an incoming call indication designating that an associated incoming call is latency-sensitive, the radio access network will preferably assign the incoming call to an access gateway that is one with a measured respective round trip latency less than or equal to a median measured respective round trip latency. Additionally, the radio access network maintains a profile for at least some wireless communication devices that use its services. When the radio access network receives an incoming call indication for a wireless communication device, the radio access network preferably determines, from the wireless communication device's profile, if the wireless communication device has a history of heavy network usage. If the wireless communication device has a history of heavy network usage, the radio access network preferably assigns the incoming call to an access gateway that is one with a measured respective round trip latency greater than or equal to the median measured respective round trip latency.

Method and system for managing handoff in a radio access network

Abstract: Disclosed is a method and device for managing handoff of an access terminal in a radio access network (RAN). An access terminal may detect a handoff trigger, determine whether there is an ongoing data transfer in progress, determine an amount remaining in the data transfer, compare the amount remaining to a threshold amount, and delay or cancel the handoff if the amount remaining is below the threshold amount. Additionally, the access terminal may consider signal strength of the current (source) coverage area in determining whether to delay or cancel the handoff.

Avoiding satellite interference to long term evolution systems

Abstract: A computer-implemented method, system, and computer-readable storage media for scheduling physical resource blocks are provided. Base stations, of a communication radio access network, may be configured with schedulers that assign one or more physical resource blocks to a communication channel of a wireless device based on distance or power. The physical resource blocks allow the wireless device to communicate with the base station. Some resource blocks may be monitored across multiple sites to determine whether an aggregate power for the resource blocks exceeds a threshold. When the aggregate power threshold is surpassed, the schedulers may limit or prevent use of the identified resource blocks.

Wireless device network rescan rate determination based on wireless coverage availability

Abstract: What is disclosed is a method of operating a wireless communication device. The method includes receiving home wireless access to communication services over a first wireless communication mode from a home wireless access node associated with a first wireless system identifier, and determining availability of roaming wireless access over a second wireless communication mode from a roaming wireless access node. The method also includes processing the first wireless system identifier to determine a first geographic group associated with the home wireless access node, and determining a network rescan timer for the roaming wireless access over the second wireless communication mode based on the first geographic group and the availability of the roaming wireless access.

Method and system for improving access to emergency services over a shared wireless communications medium

Abstract: Disclosed is a method and system for improving access to emergency services via a communication system including a shared wireless communications medium. A requesting wireless communications device receives dialed digits matching a predetermined dialed destination associated with an emergency contact and attempts to place a call to the dialed destination. Responsive to a failure of the attempt to place the call and to the matching, the requesting wireless communications device broadcasts a signal to cause at least one nearby wireless communications device to release at least a portion of communication system resources currently in use so as to thereby allow the released communication system resources to be subsequently used by the requesting wireless communications device. The requesting wireless communications device may then re-attempt the call with improved chances of connecting in light of the released resources.

Optimization of resource polling intervals to satisfy mobile device requests

Abstract: Systems and methods for optimizing a polling interval to capture new or changed content at an application server in a wireless network are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, for polling the application server using a first polling interval, monitoring responses received from the polling of the application server, adjusting the first polling interval to a second polling interval for polling the application server and/or using the second polling interval for polling another resource delivering same or similar content as the application server.

Mobile application traffic optimization

Abstract: Systems and methods for mobile application traffic optimization are disclosed. In one aspect, embodiments of the present disclosure include a distributed proxy and cache system, including, a local proxy on a mobile device for intercepting a data request made via a mobile device, and a proxy server coupled to the mobile device and a content server to which the data request is directed. In one embodiment, the local proxy can forward the data request to the proxy server for transmission to the content server for a response to the data request. In addition, the proxy server sends the data request to the content server independent of activities on the local proxy and notifies the local proxy when changed or different content on the content server is detected for the data request. One embodiment of the distributed proxy and cache system further includes a cache shared between the local proxy and the proxy server and the component on the local proxy and is queried for a locally stored response to the data request prior to the data request being forwarded on to the proxy server.

Systems and methods for ofdm with flexible sub-carrier spacing and symbol duration

Abstract: Embodiments are provided for supporting variable sub-carrier spacing and symbol duration for transmitting OFDM or other waveform symbols and associated cyclic prefixes. The symbol duration includes the useful symbol length and its associated cyclic prefix length. The variable sub-carrier spacing and symbol duration is determined via parameters indicating the sub-carrier spacing, useful symbol length, and cyclic prefix length. An embodiment method, by a network or a network controller, includes establishing a plurality of multiple access block (MAB) types defining different combinations of sub-carrier spacing and symbol duration for waveform transmissions. The method further includes partitioning a frequency and time plane of a carrier spectrum band into a plurality of MAB regions comprising frequency-time slots for the waveform transmissions. The MAB types are then selected for the MAB regions, wherein one MAB type is assigned to one corresponding MAB region.
