20080254793 | System accounting in a multiprocessor environment - In one embodiment, a method can include: (i) assigning an attribute to each of a plurality of processors, and designating one of the plurality of processors as a proxy processor; (ii) when a user session begins using a first of the plurality of processors, sending a first notification message to a server; and (iii) when a rebooting of the first processor occurs: (a) suppressing a second notification message from the first processor in the proxy processor; and (b) sending a third notification message with the attribute to the server to enable the server to modify a user file in the server using the attribute. | 10-16-2008 |
20080317053 | LOAD-BALANCED NSAPI ALLOCATION FOR iWLAN - In one embodiment, a load balancer receives a message from a tunnel termination gateway (TTG) associated with a mobile device. The load balancer may receive messages from a plurality of TTGs. A gateway node in a plurality of gateway nodes in which to send the message is determined. The load balancer then assigns a NSAPI for use by the gateway node. For example, the NSAPI may be associated with a tunnel that is generated between the TTG and GGSN. The load balancer ensures that the assigned NSAPI is not currently in use at the gateway node. Thus, no overlapping of NSAPIs may occur even though the load balancer is processing messages from multiple TTGs for multiple gateway nodes. | 12-25-2008 |
20090023426 | INTELLIGENT REAL ACCESS POINT NAME (APN) SELECTION USING VIRTUAL APNS - In one embodiment, a first access request is received from a mobile device. The access request may be received through a first access medium for a virtual access point name (APN). A session is created with a service using a first real access point name (APN) for the mobile device. A second access request is received through a second type of access medium. The request may be received through a second virtual APN. A session is determined that is active for the mobile device through the first access medium and the second access request is assigned the first real APN even though the request is received through a second access medium. The continuity of the connection may then be maintained because the first real APN is still being used. In this case, a handoff of the connection from the first access network to the second access network is performed while the connection to the service is maintained through the first real APN. | 01-22-2009 |
20090116513 | System and Method for Providing Single IP Tunnel - In one embodiment, a method includes receiving a packet at a network processor, and determining the packet is to be directed to a selected one of a plurality of traffic processors if a tunnel endpoint identifier of the packet is associated with a subscriber terminal. The method further includes determining that the packet is to be directed to the selected one of the plurality of traffic processors if a destination address of the packet is associated with the subscriber terminal. The method still further includes distributing the packet to the selected one of the plurality of traffic processors. | 05-07-2009 |
20120250509 | SOFT RETENTION FOR CALL ADMISSION CONTROL IN COMMUNICATION NETWORKS - Systems and methods are disclosed for receiving a request at a packet gateway to allocate a new bearer for a mobile device on a wireless telecommunications network; identifying, at the packet gateway, existing bearers that have a quality of service (QoS) that can be reduced without dropping the existing bearers; reducing, at the packet gateway, the QoS of the existing bearers; reclaiming resources at the packet gateway that were previously in use by the existing bearers; and allocating the new bearer for the mobile device using the reclaimed resources at the packet gateway without causing any of the existing bearers to be disconnected, wherein the existing bearers have a lower priority than the new bearer, and wherein the existing bearers have previously been designated as capable of being preempted. | 10-04-2012 |
20130144906 | SYSTEMS AND METHODS FOR CLIENT TRANSPARENT VIDEO READDRESSING - Network operators are striving to find ways to provide stable video services amid a rapid increase in video traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes using a content adaptation engine (CAE). However, network operators failed to efficiently readdress video flows to CAEs. This disclosure provides systems and methods for efficiently readdressing video flows to CAEs. | 06-06-2013 |
20130144979 | SYSTEMS AND METHODS FOR INTELLIGENT VIDEO DELIVERY AND CACHE MANAGEMENT - Network operators are striving to find ways to provide stable video services amid a rapid increase in video data traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes and to cache videos for future use. However, network operators failed to exploit user information and to leverage benefits of distributing these functionalities across the network. This disclosure provides systems and methods for efficiently delivering video and managing video caches by exploiting user information and by distributing video delivery functionalities across the network. | 06-06-2013 |
20130167181 | WIRELESS TCP LINK STATE MONITORING BASED VIDEO CONTENT ADAPTATION AND DATA DELIVERY - Systems and methods are used for receiving a video request from a user equipment for video to be downloaded; determining a link bandwidth status associated with the user equipment; in response to the link bandwidth status associated with the user equipment, determining whether to implement one or more additional processing functions associated with the video delivery; during the video delivery, repeating the determining such that the one or more additional processing functions associated with the video delivery can be implemented or not implemented at different times during the video delivery. These processing functions can include transrating, HTTP optimization, TCP optimization, and video pacing. | 06-27-2013 |

20130332620 | STABILIZATION OF ADAPTIVE STREAMING VIDEO CLIENTS THROUGH RATE LIMITING - In one embodiment, a method includes identifying a current encoding rate requested by a client device for content received from a content source, setting at a network device a rate limit to limit the rate at which the content is received at the client device based on the current encoding rate, and adjusting the rate limit based on changes in the current encoding rate. The rate limit is set to allow the client device to change the current encoding rate to a next higher available encoding rate. | 12-12-2013 |
