Abstract: Systems and methods that handle partial Charging Data Records (CDRs) for a session. An offline charging system includes a cluster of Charging Gateway Functions (CGF). A first CGF of the cluster receives a first Fully Qualified Partial CDR (FQPC) for a session, and stores FQPC data based on the first FQPC in a centralized storage module that is accessible by each of the CGFs in the cluster. A second CGF of the cluster receives a Reduced Partial CDR (RPC) for the session responsive to a failure of the first CGF, retrieves the FQPC data from the centralized storage module, and generates a second FQPC for the session based on the RPC and the FQPC data retrieved from the centralized storage module.

Abstract: A method, a wireless transmit/receive unit (WTRU) and a base station for transferring small packets are described. The WTRU generates a packet that has one or more of a medium access control (MAC) or a physical layer convergence protocol (PLCP) header, the one or more of the MAC or the PLCP header including a field. On a condition that the WTRU has data buffered for transmission, the WTRU includes in the field information that indicates a time or a transmission opportunity (TXOP) needed to transmit at least one packet of data that the WTRU has buffered for transmission. The WTRU transmits the packet to another WTRU in the wireless network. The WTRU receives another packet from the other WTRU with a granted TXO) based on the time needed to transmit the at least one packet of the data that the WTRU has buffered for transmission.
Abstract: A first wireless access network node receives, from a second wireless access network node, delay information relating to a delay in buffering data at a protocol layer in the second wireless access network node. The first wireless access network node configures a discard timer based on the received delay information for a packet to be sent to a user equipment.
Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE monitors a first component carrier and at least one second component carrier of a plurality of aggregated component carriers for a service and configuration information associated with the service. The UE receives the service concurrently via the first component carrier and the at least one second component carrier. At least one of the first component carrier or the at least one second component carrier carries the service via broadcast.
Abstract: Methods and apparatus for using communications channels corresponding to frequency bands subject to cellular network, e.g., LTE, interference and/or other interference are described. The methods are well suited for use of cable networks where communications over a coax cable or via cable device may be subject to LTE interference. In various embodiments data traffic is classified based on whether the traffic corresponds to a protocol that supports a retry communications mechanism in the event of a communication error, the type of traffic data and/or the priority of the traffic data. In some embodiments data being communicated using a protocol which supports a retry mechanism are routed over channels subject to interference even if, in some cases, the packets correspond to data which has a higher priority or QoS requirements than packets, e.g., best effort packets, which are transmitted using a protocol that does not support a packet retry mechanism.
Abstract: An apparatus includes a separator for selectively separating audio from input signals including video with audio, a switcher for selectively transferring the input signals to at least one output, a multiplexed path for sending the separated audio signal to the at least one output, the at least one output being configured for selectively directing the input signals and separated audio signals.
Abstract: A method for attaching a user terminal to a packet network via a meshed radiocommunications network infrastructure includes selecting a host packet network dedicated to at least a category of users to which a user terminal belongs based on a second user identification code of the meshed network and/or access information pertaining to rights for attachment of user terminals to at least one packet network. The method finds an application in all types of infrastructure of meshed radiocommunications networks and finds a particularly interesting application in the case of PMR type professional radiocommunications networks.
Abstract: The present invention relates to configuring search spaces of at least two coexisting control channels in a communication system. In particular, the control channels are defined in at least partially overlapping regions, wherein the overlapping is in the time and/or frequency domain. This configuration enables coexistence of the at least two channels in the same resource grid and better utilization of the resources. Furthermore, it enables sharing of the reference signals.

Abstract: Disclosed herein are methods and systems for allocating resources from component carriers to a public-safety mobile radio. An embodiment takes the form of a process that is carried out by carried out by a Long-Term Evolution (LTE) Evolved Node B (eNodeB). The eNodeB makes a first determination to allocate resources to a given mobile radio. The eNodeB makes a second determination that the given mobile radio is a public-safety mobile radio. In response to making the first and second determinations, the eNodeB selects, based on one or more public-safety-communication criteria, a component carrier from among a plurality of component carriers managed by the eNodeB. The eNodeB allocates resources on the selected eNodeB component carrier to the given mobile radio.

Abstract: Recursive optimization algorithms can be used to determine which idle photonic switching elements to configure in N×N switching fabrics to achieve crosstalk suppression. Different algorithms are used to achieve different levels of optimization. Embodiment full optimization techniques may configure all inactive cells to reduce crosstalk, and consequently may provide the best noise performance and highest power usage. Partial optimizations may configure fewer than all inactive cells to reduce crosstalk, and may provide sub-optimal noise performance at lower power usages. Differential partial optimization algorithms configure inactive cells in different stages of a photonic switching fabric. Fewer than all cells in a given stage may be configured by some algorithms.

Abstract: According to one embodiment, a non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operation comprising: determining that a client device, in a first Internet Protocol (IP) subnet, is subscribed to a multicast group; determining that the client device is no longer in the first IP subnet; responsive to determining that the client device is no longer in the first IP subnet, transmitting a message on behalf of the client device to unsubscribe the client device from the multicast group is shown.
Abstract: Per-station realm lists are dynamically generating per-station for hot spot connections to access points by roaming stations. A query for a list of realms is received from a roaming station when connecting to a hot spot. Using an MAC address or other station identity, a list of available realms narrowed to a subset of per-station realms sent to the station. Narrowing is performed on-the-fly with respect to at least one aspects. A last N realms are retrieved from a database record searched by MAC address. The list is further narrowed by removing realms that are inaccessible or otherwise recently shown to have bad link quality. Additional ranking factors can narrow or rearrange the realm list based on financial agreements, popularity, trends, and the like. A selection from the list of realms is received from the station. The access point then authenticates the station with the selected realm.
