Abstract: Methods, systems, and apparatus including computer programs encoded on a computer storage medium, for retrieving image search results using embedding neural network models. In one aspect, an image search query is received. A respective pair numeric embedding for each of a plurality of image-landing page pairs is determined. Each pair numeric embedding is a numeric representation in an embedding space. An image search query embedding neural network processes features of the image search query and generates a query numeric embedding. The query numeric embedding is a numeric representation of the image search query in the same embedding space. A subset of the image-landing page pairs having pair numeric embeddings that are closest to the query numeric embedding of the image search query in the embedding space are identified as first candidate image search results.

Abstract: A micro-cellular radio communications system (microsystem) is arranged to re-use radio frequency channels which are assigned for use in a cellular radio system (macrosystem) in the same vicinity. The microsystem maintains a list of each frequency channel which is in current use in any microcell of the microsystem. In each microcell of the microsystem a signal characteristic, for example received signal strength, of each frequency channel, is repeatedly measured when the channel is not in current use in any microcell of the microsystem, and the measurements are used to determine a long-term statistical preference for re-use of a favoured set of the frequency channels in that microcell. For each microcell, the frequency channels in the favoured set are given a short-term order for actual use in dependence upon frequent measurements of the signal characteristic for the microcell regardless of whether or not the channel is in current use in any other microcell of the microsystem.

Abstract: The provisioning process of the present invention first determines the average number of units of the system resource that are held per call. This parameter is a function of the call model and call-related event holding times. The average number of units is used, along with the Busy Hour Call Attempts to determine the holding rate, Rresource, of that particular call-related event to be allocated memory. The holding rate is then used by ┌Rresource +7{square root over (Rresource)}┐ to determine the number of resources required to be allocated to the call-related event.

Abstract: A next generation wireless data system and method for handoff from a node in a network is presented. The system includes a core network (CN) and a source and a target radio network subsystem (RNS). The interface between the RNSs is enhanced to reduce unnecessary relay of messaging through the CN and thus will reduce traversing delays as well as the resources utilized in message processing. Two separate methods are proposed for handing off the data traffic to the target RNS at the CN packet processing node. These methods are a multi-cast function that concurrently sends data to the source RNS and the target RNS, and a suspend/resume function which suspends the data flow towards the source RNS and resumes the flow towards the target RNS.

Abstract: An improved method and system for limiting data packet transmission within a digital mobile telephone communication network, such as a code division multiple access (CDMA) mobile telephone communication network, by discarding unsuccessfully transmitted radio link protocol frames is disclosed. A code division multiple access (CDMA) mobile telephone communication network includes a mobile telephone, a base station, a mobile switching center, and a network Interworking Function. Within the CDMA mobile telephone communication network, each point-to-point protocol data packet is typically divided into multiple radio link protocol frames before their transmissions over an air link. In accordance with a method and system of the present invention, a marker bit is provided for each of the radio link protocol frames. The marker bit can be part of the frame header and will be removed before air link transmission. The marker bit of a first one of the radio link protocol frames is set to a first logical state (such as a logical “1”) and the rest of the radio link protocol frames are set to a second logical state (such as a logical “0”). In response to an unsuccessful transmission of one of the radio link protocol frames, all of the radio link protocol frames within the same point-to-point protocol data packet having the marker bit set to the second logical state are discarded, after a predetermined number of unsuccessful re-transmission attempts.

Abstract: A system and method for GPRS MAC procedures to support delay-sensitive, real-time traffic is presented. The system comprises a mobile station able to transmit packets to and receive packets from a base station, where the base station is coupled to a General Packet Radio Service (GPRS) network, and where the GPRS network is coupled to a data network. In an uplink dynamic scheme, the base station receives an empty packet from the mobile station. The base station releases a bandwidth allocated to the mobile station if an implementation dependent time expires and further allocates a reduced portion of the bandwidth to the mobile station if a number of the empty packets are received or if a control packet requesting additional bandwidth is received by the base station. In an uplink fixed scheme, the base station allocates a fixed number of radio resources to the mobile station. The base station releases the radio resources allocated to the mobile station, if the fixed number of radio resources are not utilized and further allocates a reduced bandwidth to the mobile station if a number of empty packets are received.

Abstract: An overload control for a central processor in the switching network of a mobile radio system. The central processor may be part of a Mobile services Switching Center (MSC). Congestion reports, based on the delay experienced by messages awaiting processing at the central processor, are broadcast to peripheral processors. The peripheral processors may be located in the MSC at interfaces of the MSC to other network elements such as base stations, the PSTN, other MSCs. Peripheral processors maintain variable message origination thresholds responsive to the congestion reports.
