Abstract: A sub-frame is generated for each MSDU to be aggregated in an A-MSDU and the sub-frame is stored in place in memory. For each sub-frame, an MSDU descriptor identifying the memory location of the sub-frame is stored in a queue. When a transmit opportunity for an MPDU arises, a DMA engine sequentially transfers the components of sub-frames stored in memory to a PHY layer using a list or other sequence of DMA descriptors obtained from at least a subset of the MSDU descriptors. Thus, these MSDU descriptors allow the aggregation of A-MSDUs to be initiated while the MSDUs are in place in the same memory in which they were initially stored.

Abstract: This application describes how Session Description Protocol (SDP) preconditions signaling can be enhanced to support lead role negotiation, precondition capability exchange, premature precondition attempts and concatenated preconditions processing. The application describes the use of send and receive tags in an SDP message for a given media line.

These additions lead to a greater chance of successful session set-up completion, reduce the number of signaling exchanges in general, and enable precondition attempts to be started earlier and to be executed in parallel.

Abstract: The present invention establishes a process for creating a set of structures that allows efficient storage and subsequent handling. The multigraph is represented using bitmaps with element counters and mappings between values and organized bitmaps to faciliate the handling of the multigraphs. The bits in the bitmaps represent two aspects of the multigraph: 1) indexing of all the objects of the multigraph as a function of their identifiers and 2) connectivity between objects of the multigraph, whether they are vertices or edges. Mappings allow, given a value, accessing the objects of the multigraph which contain such value. Multigraph operations are solved by accessing the mappings and applying logical operations on the bitmaps. This way of representing a graph allows efficiently performing graph operations such as: inserting a vertex or an edge, inserting an attribute, acquiring the incoming and outgoing edges of an attribute, etc.

Abstract: An improved method and system for removing operating restrictions associated with a predetermined subscriber identity module (SIM) from a wireless device. A user is allowed to securely log onto a Web site that contains support information on subscription plans, billing, termination, penalties, and device-to-SIM unlocking.

A user terminal makes a phone call to a subscriber terminal through a network having server. The subscriber terminal is associated with an IP address located at the server. A dynamic database of telephone numbers that ring the subscriber terminal resides at the IP address on the server.

Methods and computer-readable media containing instructions for performing the methods of the temporary phone number system are described.

Abstract: A system manages a buffer having a group of entries. The system receives information relating to a read request for a memory. The system determines whether an entry in the buffer contains valid information. If the entry is determined to contain valid information, the system transmits the information in the entry in an error message. The system may then store the received information in the entry. In another implementation, the system stores data in one of the entries of the buffer, removes an address corresponding to the one entry from an address list, and starts a timer associated with the one entry. The system also determines whether the timer has exceeded a predetermined value, transferring the data from the one entry when the timer has exceeded the predetermined value, and adds the address back to the address list.

Abstract: Each node of a virtual network can store only a predetermined number of address links to other nodes. In response to receiving a link request between a first node and a second node, it is determined whether both the first and second nodes have less than the predetermined numbering their lists. If this condition is satisfied, the address of the first node is inserted into the second node's list and the address of the second node is inserted into the first node's list. If this condition is not satisfied, it is determined whether the first node list has at least two less than the predetermined number and, if so, then the link between the second and third nodes is broken and they are instead newly linked to the first node.

Abstract: An integrated egress/replay memory structure is provided with split rate write and read ports and means for managing at least three types of data moving into, through and/or out of the integrated memory structure, namely: (1) currently egressing packet data; (2) replay data; and (3) to-be egressed data. Additionally, a shared free space (4) is managed between the storage areas of the (2) replay data and (3) the to-be egressed data. The to-be egressed data (PdBx) is allowed to enter into (to be written into) a front-end raceway portion of the integrated memory structure at a rate which can be substantially greater than that allowed for corresponding egressing packet data (PdUx). Thus, even when egressing packet data that is ahead in line is shifting out toward a slow rate egress port, this slowing factor does not slow the speed at which the to-be egressed data (PdBx) can be shifted into the front-end raceway portion.

Abstract: A method and apparatus for managing protocol information used in exchanging communications is provided. One or more protocol profiles are stored. Each of the protocol profiles is associated with a protocol. One or more transaction profiles are stored. Each of the transaction profiles identifies a combination of protocol profiles. One or more trading partner transaction profiles are stored. Each of the trading partner transaction profiles identifies a configuration of protocols for exchanging communications with a receiving party. After storing the profiles, a particular parameter value of a particular protocol profile is updated to identify an updated value without updating any of the transaction profiles. Updating the particular parameter value causes the updated value to be inherited by at least one of the transaction profiles. An application may obtain the updated value by accessing a profile that references the particular protocol profile.

Abstract: This application describes how Session Description Protocol (SDP) preconditions signaling can be enhanced to support lead role negotiation, precondition capability exchange, premature precondition attempts and concatenated preconditions processing.

These additions lead to a greater chance of successful session set-up completion, reduce the number of signaling exchanges in general, and enable precondition attempts to be started earlier and to be executed in parallel.
