摘要： A system and method for providing multi-processor data plane architecture have been provided. The method comprises selecting several processing units for performing an egress data process and an ingress data process. A number of processing units are selected for performing an egress data process based on a type of switch and data rate. Several processing pipes are provided for each processing unit. Each processing pipe is divided into several processing stages based on a number of lookup tables used in the egress data process and the ingress data process to absorb a response time of a memory device. The data is stored in several databases in each processing unit, and the databases are copied into several banks to increase an access time with a storage device, such as DDR-SDRAM. Several headers are resynchronized using a fixed delay time through an ACL unit.

摘要： Intersection signaling method for bearer management in a communication network with transporting bearer resource request message of both the UE and RN via Base station to managing entity of RN within EPC, as a signaling message over uplink channel referred to as ‘Union of Resource Request (UR Request)’ message. The bearer resource response message from one of the managing entity of UE or managing entities of UE and RN within EPC are transported as a signaling message to Evolved Packet Edge (EPE) via Base station over the downlink channel referred to as ‘Intersection of Admission Response (IA Response)’. This manages bearer setup signaling as a single loop, by transportation of ‘UR Request’ signaling message and receiving one “IA Response” signaling message over uplink and downlink channels respectively. EPE is a conglomeration of network nodes.

摘要： Embodiments herein relate to a method, telemetry aggregator and system for transmitting data from a plurality of telemetry devices to an evolved nodeB (eNodeB) over wireless communication network. A telemetry aggregator (TA) is placed in between the telemetry device and the eNodeB. The TA is placed close to the power source. This ensures that even the low power telemetry devices can transmit the data over the mobile network. The TD transmits plurality of data frames to the TA. The TA aggregates and assembles the plurality of data frames into an aggregated data frame. TA then transmits the aggregated data frame to the eNodeB at a preferred time and frequency. Since the plurality of data frames are aggregated, there is no need for the eNodeB to be connected with the Internet of Things (IoT) devices or TD for the processing of the control messages and the data.

摘要： The invention provides for method, system and node for ‘System Information’ (SI) message communication in an LTE deployed wireless communication system comprising of mapping at least a System Information Block (SIB) message into a System Information (SI) message in which SIB messages of same periodicity are mapped to a single SI message. The method further comprising segmenting dynamically the SI message exceeding predefined threshold value of SI bits known a priori that can be transmitted in any one subframe and transmitting the segmented SI messages in the corresponding SI-window wherein, the transmitted segment is indicated as part of previously transmitted segment via one bit indication taken out from the maximum number of bits that can be transmitted in a subframe and wherein if the indication bit is set to ‘1’ then the segment is part of previous frame that had non-zero indication bit and if indication bit is ‘0’ then the segment is the last segment of the System Information message. The method further decodes the segment by de-scrambling SI-RNTI; buffering the received segments based on indication bit; and assembling the received segments to form a single SI message, upon receiving the last segment indicated by the indication bit.
