Abstract: A method of providing access to telecommunication services involves receiving a routing information request for terminating a communication with a mobile station located within a visited geographic region, the routing information request including a directory number local to the visited geographic region. A subscriber identity associated with the received directory number is then dynamically selecting from an evaluation of a decision tree, the decision tree associating a reference directory number with a plurality of reference subscriber identities. Each reference subscriber identity is associated with a telecommunications service user, each user being registered to receive telecommunication services within a respective home geographic region, the home geographic region being different from the visited geographic region. The mobile station receives access to the telecommunication services within the visited geographic region via the selected subscriber identity.

Abstract: A method and system for operating a standalone client in a dual-mode mobile communications device to hand off a call between first and second wireless networks operating under different communications protocols, using Session Initiation Protocol (SIP) and ISDN User Part (ISUP) signalling. The standalone client-side application, or handoff agent, directly controls handoff of the call to the second wireless network until at least one new media stream to connect the dual-mode mobile communications device to the second device is established over the second wireless network. The standalone client-side application solely originates and controls an exchange of messages at the application layer, the exchange of messages modifying the communications channel.

Abstract: A capability of a device may be registered to an adapter. This capability may characterize the device in terms of tasks performing abilities that may be available or associated therewith. When a packet of data including a task to be handled is received at the adapter, based on the capability registered earlier for the device, the adapter may determine whether to assign the task to the device. An indication, such as packet processing information may be derived from the packet to assist in distribution of the task. By comparing the indication with the capability, the task may be offloaded to the device based on the comparison. Using the device for a networked device, in one embodiment, one or more network communication tasks associated with data communications may be distributed and optionally performed within an adapter. In this way, the networked device may be spared of undertaking network communication tasks that are conventionally performed within the networked device.

Abstract: A method, apparatus, and article for caching security records for access by a hardware offloading device are disclosed. A method for updating security record entries in a hardware table is disclosed that includes marking every security record entry in the hardware table as a replacement candidate based upon passage of a determined time interval, each security record entry having a set of security parameters. Upon receiving a packet having a security record, the hardware table is checked for a security record entry corresponding to the security record. A check is done to determine whether there is a replacement candidate in the hardware table if there is no security record entry corresponding to the security record. The security record entry containing the replacement candidate is replaced with the security record if there is a replacement candidate. Other embodiments are described.

Abstract: The data storage system comprises a scalable number of routing processors (RPs) through which clients of a network communicate. The storage system also includes a scalable number of storage processors (SPs) connected to a scalable number of storage units (SUs). This data storage system provides a new and hybrid approach which lies in between conventional NAS and SAN environments. It creates a unified and scalable storage pool accessible through a single consistent directory without the need for a metadata controller (MDC). There is thus no table lookup at a central node and no single point of failure. It allows a dissociation of the relationship between the physical path and the actual location where the data objects are stored.

Abstract: A diagnostic technique is disclosed for use in high-load, low-latency communication systems involving encrypted communications. During diagnostic operation, an encryption engine is placed in an offline mode to determine whether security records stored by the engine have been corrupted. In the offline mode, the encryption engine is provided with test data to be either encrypted or decrypted. The encryption engine processes the test data using the same algorithms and the same security records that would be used if it were operating on any other data in an online mode. The encryption engine then returns the processed data to its source. At the source, the processed data is compared to data that should have been generated if the encryption engine were using a correct security record. If they do not match, the security record is identified as corrupted.
