| 41 | Enhanced self-organizing network switching matrix | US15141919 | 2016-04-29 | US09622274B2 | 2017-04-11 | Gary Edward Chow |
| Automated control of simulcast ratios based on network traffic data provides efficient network capacity management. In one aspect, a remote switching matrix can be utilized at a venue to couple remote transceiver units (RTUs) with different antenna ports, for example, of one or more multi-beam antennas deployed at the venue. A simulcast ratio that can be utilized to support traffic demand at the venue can be determined and implemented by creating dynamic connections between the RTUs and the antenna ports. In one aspect, the simulcast ratio can be modified based on changes in network traffic at the venue that are monitored via self-organizing network devices. In addition, one or more antenna beams of the multi-beam antennas are remotely steered or rotated based on a location of the traffic. | ||||||

| 43 | Feedback Based Adaptation Of Multicast Transmission Offset | US15100753 | 2013-12-16 | US20160373267A1 | 2016-12-22 | Ibtissam El Khayat; Prabaharan Kanesalingam; Jie Ling |
| A node (260) of a cellular network node sends data units to a group of base stations (200). Each data unit is configured for conveying multicast data to be sent by the base stations (200) in a synchronized manner at a starting time indicated in the data unit. For each of the data units, the node (260) determines the starting time as the sum of the time of sending the data unit from the node and an offset value. Further, the node (260) obtains feedback information from the base stations (200) of the group. The feedback information indicates a deviation of the starting time indicated in one of the data units (411) from an earliest possible time of sending the multicast data from the data unit (411) by the base stations (200) of the group. Depending on the feedback information, the node (260) adapts the offset value. | ||||||

| An apparatus and method for controlling a transmission timing of push messages in a system that provides a location-based push service. An electronic device transfers its own network information to a push server when connecting to the push server. The push server classifies electronic devices based on network information. At startup, the push server divides the electronic devices classified based on the network information into a plurality of groups, each including a predetermined number of electronic devices, and transmits push messages per unit of the groups. The push server measures a response time period taken to receive acknowledge messages in response to the push messages in a group, and adjust a waiting time for correcting a transmission time of push messages based on the response time period. The push server transmits push messages to electronic devices of the next group based on the adjusted waiting time. | ||||||

| 51 | Method in a cellular radio communications system | US09089726 | 1998-06-03 | US06434396B1 | 2002-08-13 | Johan Rune |
| The present invention relates to a method in a cellular radio communications system of minimising the set-up delay for a mobile terminated message, which is divided into one or more data units (DU1-DUi). The inventive method is carried out by multicasting the message (DU1-DUi) to at least two selected base stations (BS1-BS4) in the vicinity of the mobile station (MS). Thereafter, at least one first data unit (DU1) of the message (DU1-DUi) is simultaneously transmitted in an initial signal (P(DU1)), which is sent out from the base stations (BS1-BS4) and directed to the mobile station (MS). Any subsequent data units (DU2-DUi) in the message (DU1-DUi) are unicast (BS2; CHX(DU2)-CHX(DUi)) to the mobile station (MS), via one of the originally selected base stations (BS2). The mobile station (MS) returns a positive acknowledgement (ACK) after each correctly received data unit (DU1-DUi). | ||||||
| 52 | Supporting fast intra-domain handoffs and paging in wireless cellular networks | US09798468 | 2001-03-02 | US20010036834A1 | 2001-11-01 | Subir Das; Ashutosh Dutta; Archan Misra; Anthony J. McAuley; Sajal K. Das |
| A method and system for fast intra-domain handoffs. In accordance with the method a mobility agent performs a duration limited multicast of packets destined for a mobile node to a well-defined set of subnet agents that form a multi-cast group. The well defined set includes the neighboring subnet agents of the subnet agent currently serving the mobile node. Once the multicast group is established the mobility agent then tunnels packets destined for the mobile node to each member of the multicast group. The members of the multicast group, i.e., the current subnet agent and its neighboring agents, then buffer the packets destined for the mobile node for a limited. When the mobile node then requests an IP address on the new subnet it is moving to, i.e., a local care-of address, the corresponding subnet agent then transmits the packets destined for the mobile node to the mobile node. The limited duration multicast concept is further extended by defining a paging area and using a multicast within the paging area to reduce the frequency of intra-domain handoff updates. | ||||||
