| 20090296613 | METHOD AND APPARATUS FOR PROVIDING QUALITY-OF-SERVICE IN RADIO ACCESS NETWORKS - The invention includes a method and apparatus adapted for providing quality-of-service to a packet flow within a Radio Access Network (RAN). In one embodiment, a method includes receiving packets of a packet flow at a first network element of the RAN, where the packet flow is associated with an application normally served in a best effort service class of the RAN and each packet of the packet flow comprises an indication of a quality-of-service policy to be applied to the packet flow within the RAN, and, applying the indicated quality-of-service policy to the packet flow within the RAN. The quality-of-service policy to be applied to the packet flow within the RAN is based on at least one characteristic of the packet flow, which may be determined in any manner, such as using information included in the packet headers, using deep packet inspection techniques, and the like. The indication of the quality-of-service policy to be applied to the packet flow within the RAN may be set either inside the RAN or outside the RAN. | 12-03-2009 |
| 20100080123 | Method and Apparatus for Signaling Proprietary Information Between Network Elements of a Core Network in a Wireless Communication Network - The invention includes a method and apparatus for signaling proprietary information between network elements of a core network (CN) of a wireless communication network. A method for signaling proprietary information within the CN includes encoding the proprietary information in an IPv4 Options field of an inner header of an IP packet, and pre-pending an outer header to the IP packet for Mobile IPv4 (MIPv4) tunneling the IP packet from a first node of the CN to a second node of the CN. The first and second nodes of the CN may include a mobility anchor node and a mobility gateway node, respectively. The first and second nodes of the CN may include a mobility gateway node and a mobility anchor node, respectively. A method for signaling proprietary information includes receiving a tunneled IP packet at a first node of the CN (where the IP packet includes an outer header, an inner header, and a payload), removing the outer header from the IP packet, stripping an IP Options field from the inner header of the IP packet where the IPv4 Options field includes the proprietary information, and propagating the proprietary information from the first node of the CN to a second node. The first node of the CN may be a mobility gateway node and the second node may be a node of a radio access network (RAN). The first node of the CN may be a mobility anchor node and the second node may be another node of the CN. | 04-01-2010 |
| 20100080153 | METHOD AND APPARATUS FOR PRIORITIZING PACKETS FOR USE IN MANAGING PACKETS IN RADIO ACCESS NETWORKS - The invention includes a method and apparatus adapted for managing packets within a Radio Access Network (RAN). A method includes receiving a packet within the RAN, determining a packet priority assigned to the packet, and managing the packet within the RAN based on the packet priority of the packet and a condition of the RAN. The packet priority assigned to the packet is based on at least one characteristic of the packet, which is determined based on packet contents of the packet. The at least one characteristic associated with the packet comprises information available at or above the network layer. The packet priority may be assigned to the packet within the RAN and/or outside of the RAN. The management of the packet within the RAN may include managing assignment of RAN resources to the packet (e.g., processor resources, radio resources, and the like), directing an access device to use a proscribed resource allocation, managing scheduling of the packet for transmission over the air interface of the RAN, and the like, as well as various combinations thereof. | 04-01-2010 |

Another example embodiment includes receiving an IP packet at the RAN from the core network; extracting information from a destination options extension header of the IP packet at the RAN; and sending the IP packet from the RAN to a terminal. | 05-27-2010 |
| 20110069666 | METHOD AND APPARATUS FOR MANAGING ALLOCATION OF RESOURCES IN A NETWORK - To manage resource allocation between users of a wireless or wireline network, recent resource usage by each user is determined and priorities are assigned accordingly. Then, the network resources are allocated according to the assigned priorities. A respective priority of a user may be inversely proportional to the recent resource usage by that user. To facilitate continuous fair distribution of the network resources, the users may be re-prioritized and resources are re-allocated accordingly. Information about recent resource usages by the users is continuously accumulated, including about users moving from one access point of the network to another. When resource allocation for a particular access point is determined, recent resource usage for a user that has joined the access point from another access point in the network may include prior resource usage by that user at the other access point. | 03-24-2011 |
