20090086629 | ADMISSION CONTROL BASED ON QOS PERFORMANCE IN A WIRELESS COMMUNICATION NETWORK - Techniques for performing admission control based on quality-of-service (QoS) performance in a wireless communication network are described. QoS performance (e.g., delay or throughput performance) of admitted data flows may be determined. Whether to admit or reject a new data flow may then be determined based on the QoS performance of the admitted data flows. The admitted and new data flows may have delay bounds. The QoS performance of the admitted data flows may be given by a measured sector delay, which may be determined based on actual delays of packets. A measured flow delay for each admitted data flow may be determined based on delays of packets for that flow. The measured sector delay may then be determined based on the measured flow delays for all admitted data flows. The new data flow may be admitted if the measured sector delay is less than a delay threshold. | 2009-04-02 |

By initially assigning all SDUs corresponding PDCP SNs, a PDCP SN gap or hole can then be encountered upon dropping of a PDCP SDU. To manage PDCP SN gaps or holes thus generated, an internal time out can be designated to terminate an associated UE's delay for such SN hole(s) via a time out. Other aspects enable the source eNB to send a PDCP Status Message to the UE (via the target eNB) to abort the SN gaps or holes resulting from a dropped PDCP SN. | 2009-04-02 |

20090086725 | METHOD AND SYSTEM FOR TRANSMITTING MESSAGE SERVICE DATA - This invention discloses a method for transmitting message service data, which includes: adding, at a message sender, the message service data into a Session Initiated Protocol message or a Message Session Relay Protocol message, and transmitting the message service data to a message receiver through the Session Initiated Protocol message or a Message Session Relay Protocol message. The invention also discloses a system for transmitting message service data, which includes a message service data processing module, including a message adding module and a transmitting module. Different types of message service data can be transmitted according to the invention. | 2009-04-02 |
20090086726 | Service Advertisement Framework (SAF) in a Communications Network - In one embodiment, a method includes receiving a first update message at a first forwarding node from a second forwarding node of the communications network. The first update message includes forwarded service type data that indicates a type of service available via the second forwarding node, and forwarded cost data that indicates a first cost of communications to obtain the type of service via the second forwarding node. An incremental cost is determined for communications between the first forwarding node and the second forwarding node. Service data is stored at the first forwarding node. The service data indicates the type of service is associated with the second forwarding node at a total cost based on the first cost and the incremental cost. A second update message that includes forwarded cost data based on the total cost is sent over the network from the first forwarding node. | 2009-04-02 |
20090086727 | Intelligent Routing in a Hybrid Peer-to-Peer System - Intelligent routing may be provided. First, a second peer via home relay may receive presence information indicating that a first peer is connected to a first foreign relay. Then the second peer may update, in response to the presence information, a routing table to indicate that a primary place to send data to the first peer is the first foreign relay. Next, the second peer may determine from the routing table that the primary place to send the data to the first peer is the first foreign relay. Next, the home relay may receive a request from a second peer to send data to the first peer via the first foreign relay. Then, in response to determining from the routing table that the primary place to send the data to the first peer is the first foreign relay, the data may be sent to the first foreign relay. | 2009-04-02 |
20090086728 | METHODS AND APPARATUS FOR MANAGING ADDRESSES RELATED TO VIRTUAL PARTITIONS OF A SESSION EXCHANGE DEVICE - In one embodiment, a method includes receiving an IP packet associated with a first virtual partition defined at a session exchange device. The first virtual partition is associated with a first IP address space. The method also includes receiving an IP packet associated with a second virtual partition defined at the session exchange device. The second virtual partition is associated with a second IP address space having a portion that corresponds with the first IP address space. The IP packet associated with the first virtual partition is modified such that the IP packet associated with the first virtual partition has an IP address value from a third IP address space different from the portion of the second IP address space. | 2009-04-02 |
