  • Patent number: 10694504
    Abstract: Communication is implemented between at least one access node of a wireless network and a terminal attached to the wireless network. The communication is on at least one narrowband carrier (311-1, 311-2) comprising resources (308) in a first spectrum (301) and operating according to a first radio access technology, e.g., Narrowband Internet of Things, NB-IoT. The first spectrum (301) is arranged at least partly within a second spectrum (302) on which communication between the at least one access node and a second terminal is executed on a wideband carrier (312). The wideband carrier (312) comprises resources (308) in the second spectrum (302) and operates according to a second radio access technology different to the first radio access technology, e.g., Machine-Type Communication, MTC, or evolved UMTS radio access, E-UTRA. In some examples, the first spectrum (301) and the second spectrum (302) both may comprise a shared spectrum.

  • Patent number: 10686697
    Abstract: Methods for managing packets in a communication system based on Software Defined Networking are disclosed. The communication system's data plane comprises a forwarding module, a service module, and an entry module, and the communication system's control plane comprises a management module. The entry module receives an IP packet from the peer device, the IP packet including a destination IP address associated with the mobile device. The entry module obtains, from the management module, a location value specifying the radio network node associated with the destination IP address. The entry module associates the location value with the IP packet, wherein the location value is related to a location tag name, indicating the radio network node that serves the mobile device, thereby obtaining a packet. The entry module sends the packet, via the forwarding module, towards the radio network node as indicated by the location value of the location tag name.

  • Patent number: 10673677
    Abstract: Embodiments of the present disclosure describe a single carrier-based data transmission method and apparatus. The method may include generating a frame and sending the frame. A data part of the frame includes 2N data blocks, the 2N data blocks are arranged in a sequence from the first data block to the 2Nth data block. Furthermore, the data block includes a payload part and a guard interval (GI), payload parts of different data blocks are separated by GIs, and a payload part of the 2Nth data block is obtained by multiplying a payload part of the (2n?1)th data block by a phase-shift sequence, where n=1, 2, . . . , N, and N is an integer greater than 0. By using the foregoing manner, data transmission robustness can be improved and data transmission for a longer distance can be supported.

  • Patent number: 10638400
    Abstract: The specialized networking and application system includes an enforcer configured to intercept the signaling messages and select an optimal SGW, PGW, SMF/UPF and application servers in real time. More specifically, the enforcer intercepts and generates GSM MAP, Diameter, GTP-C and HTTP2/JSON signaling messages. The enforcer executes a policy to force the user devices to re-establish the data connection, thus anchoring at different SGW, PGW, SMF/UPF and application server to keep end-to-end routing path optimal, when the impacting factor changes. The enforcer can further feed its performance data and decision matrix into the analyzer and database to further optimize the decision process. Analyzer and KPI metrics databases are installed at central data centers to collect the KPI data from different probes and enforcer, calculate in real-time the optimal routing path with different decision factors considered, and interact with enforcer to update the latest optimal path status based on the data collected.
