A method, system, and medium are provided for delivering broadcast video content at varying levels of video quality. In particular, a source video stream is provided that is divided into two or more video substreams such that the video substreams include offset frames from the source video stream. The video substreams are modulated onto one or more air interface channels. Mobile devices may be configured to access only one of the video substreams to present video content at a lower frame rate or to access multiple video substreams to present video content at a higher frame rate.

Enhancing video quality for broadcast video services

Media and systems are provided for limiting bandwidth consumption in a network environment by presenting customized browser-presentable resources. A request for a base universal resource locator (URL), followed by a request for a specific resource, is received. An optimized URL for the request is generated. When a predetermined number of requests for the specific component resource are received during the course of accessing the base URL, subsequent user requests for the base URL are redirected to the optimized URL. Thus, only the specific resources are presented for display. Requests to return to the base URL can result in discontinuing redirection. Returning to the base URL and accessing additional resources can modify the enhanced URL or redirect requests for the base URL to a difference component resource. Network bandwidth usage is enhanced by recognizing repetitive user requests.

Usage-based content filtering for bandwidth optimization

Methods, media and systems are provided for generating a dynamic web portal in a wireless network, and the portal is based on personal usage. An initialized portal contains no web content. Systems include one or more network elements configured to monitor requests for resource components, to generate web portals, and to dynamically update the portals based on the requests for resource components. Data structures embodied on a computer-readable media are included for storing numerical data regarding the requests and for storing a plurality of portals. The dynamic web portal is updated to contain component resources from visited web pages, each having a respective universal resource locator (URL) or portion of code with which it is associated. Requests for resources are monitored and added to a web portal when a specified threshold is surpassed so that an updated web portal can be presented.

Dynamic portal creation based on personal usage

A method, system, and medium are provided for increasing the robustness of communications sessions between mobile devices and communications networks through handoff diversity. Separating the handoff times through handoff diversity provides for continuous transmission of data and decreases the likelihood of dropped calls and lost data. In a communications session capable of communicating data through multiple channels, handoff diversity is implemented by ensuring that at least one communication channel's handoff is complete and transferring data prior to initiating a handoff within another channel. In one illustrative embodiment, the present invention configures the physical propagation environment of the channels to create diversity in channel-handoff occurrences. In another illustrative embodiment, the communications network or mobile device is configured to force channel-handoff diversity by delaying a handoff for one or more communication channels.

Seamless inter-network handoff

Methods and apparatus for congestion mitigation in wireless communication networks are provided. The congestion mitigation can include assignment of a new user class, a mobile station identifier, a mobile station identifier and a reserved traffic channel and/or an alternative access channel in another wireless communication network. These congestion mitigation techniques can be employed for selected mobile stations when an activity on an access channel is above a threshold level.

Systems and methods for wireless communications with a heavily-loaded wireless network

A method and system for establishing group multicast communication, such as PoC multicast communication. Multiple terminals will join a PoC multicast group automatically at some point before the underlying PoC session is being initiated and thus before there is any PoC content for a PoC server to multicast to the group members. Further, this joining process will occur without the PoC multicast channel being listed in the terminals' multicast channel listings. Thereafter, when one of the terminals opts to initiate the PoC session and thus signals to the PoC server, the server will cause the participating terminals to tune to the associated PoC multicast channel for the PoC multicast group that the terminals had already joined. The invention thereby helps to effectively randomize the timing of join-signaling by the various terminals and thus helps to conserve network resources.

Advanced joining into multicast group to facilitate later communication among group members

Elimination of intermodulation interference in a wireless communication system by removing a portion of the spectrum of transmitted signals. According to a received indication of an occurrence of intermodulation interference experienced by a narrowband receiver, mappings are performed between the predetermined narrowband channel frequency on which the narrowband receiver operates and the occupied channel frequencies of at least one broadband transmit signal. Narrowband candidate frequency ranges that linearly combine into frequencies that overlap the predetermined narrowband channel frequency are determined based on the mappings. The narrowband candidate frequency ranges that potentially contribute to the intermodulation interference are then selectively filtered by at least one notch filter until the intermodulation interference is substantially eliminated.

Methods and systems are provided for dynamic allocation of carrier frequencies in wireless wide area networks (WWANs). A first base station among a plurality of base stations in a WWAN determines that a level of load in a wireless coverage area exceeds a load threshold, and responsively (i) obtains a first keycode from a keycode library, wherein the first keycode then becomes unavailable to the other base stations of the plurality of base stations, (ii) identifies a carrier frequency, and (iii) uses the first keycode to activate the identified carrier frequency in the wireless coverage area.

Dynamic allocation of carrier frequencies in wireless wide area networks

A method of operating a communication system comprises receiving a plurality of traffic, processing each traffic of the plurality of traffic to determine if a delay of the traffic exceeds a delay limit, discarding the traffic if the delay exceeds the delay limit, retaining the traffic if the delay does not exceed the delay limit, incrementing a late counter from a base amount of the late counter when the delay exceeds the delay limit, incrementing a retained counter from a base amount of the retained counter when the delay does not exceed the delay limit, returning the late counter to the base amount of the late counter when the delay does not exceed the delay limit and when the delay of a previous traffic exceeded the delay limit, clearing the retained counter to the base amount of the retained counter when the delay exceeds the delay limit and when the previous traffic did not exceed the delay limit, increasing the delay limit when the late counter exceeds a late limit, and decreasing the delay limit when the retained counter exceeds a retained limit.

Dynamic backhaul delay determination

A method and apparatus for assigning channel elements in a radio access network (RAN) based on the type of the communication requiring a channel element. When the RAN receives a request to set up a communication of a particular type with an endpoint in a given wireless coverage area, the RAN responsively determines a proportion of the channel elements that are presently assigned to communications of the particular type. If the proportion does not exceed a predetermined threshold for communications of the particular type, the RAN may assign a channel element to the communication by transmitting the necessary signaling messages to the endpoint, one of which may include an identifier of the assigned channel element. The RAN may then determine and store an indication of the type of the communication being assigned the channel element by correlating signaling messages.

Limiting channel element usage based on communication type

A method and base transceiver station (BTS) for preventing paging channel overload in a wireless communication system. Paging channel occupancy level is measured and compared to different threshold levels. Each threshold level is associated with one or more types of paging messages. If the measured occupancy level of the paging channel reaches a first threshold level of occupancy, the BTS switches to a state in which the BTS allows initial transmission of paging messages of a first type but blocks retransmission of paging messages of the first type. If the measured occupancy level of the paging channel reaches a second threshold level of occupancy, the BTS switches to a second state in which the BTS allows initial transmission of paging messages of the first type and paging messages of a second type but blocks retransmission of paging messages of the first type and paging messages of the second type.
