  • Methods and Arrangements for Managing a Retransmission by a Device on a Random Access Channel in a Wireless Communication Network
    Publication number: 20180302190
    Abstract: Methods and arrangements for managing a retransmission on a Random Access CHannel, “RACH”, in a wireless communication network (100). A device (600; 120) performs (404; 502) the retransmission on the RACH, wherein the retransmission is based on a coverage class associated with the device (600; 120). Basing the retransmission on the coverage class e.g. enables reduction of retransmission collisions when the wireless communication network (100) operates as in Extended Coverage GSM, “EC-GSM”.

  • METHOD AND DEVICE FOR HANDLING PAGING EXTENSION
    Publication number: 20180263011
    Abstract: Handling of a paging extension in a wireless communication network. A terminal device in the wireless communication network receives, from a base station in the wireless communication network, a message including an indication of a paging extension for the terminal device. The terminal device is associated with a first coverage class. Based on the message, the terminal device determines a second coverage class of a downlink transmission from the base station to a further terminal device. Then, the terminal device determines a target paging group for the paging extension based on the first coverage class and the second coverage class.

  • System and method of supporting packet-switched handover
    Patent number: 9973977
    Abstract: A system and method of supporting packet-switched handover of a mobile station (MS) from a GERAN/UTRAN cell to a Generic Access Network (GAN) cell within a GAN. If the MS is within coverage of the GAN cell, the MS registers within the GAN, triggering initiation of the packet-switched handover from the GERAN/UTRAN cell to the GAN cell. A preparation phase is then conducted for executing the packet-switched handover. The preparation phase includes identifying the MS context as part of the preparation phase and activating the GA-PSR TC towards the MS. Next, the packet-switched handover is executed, resulting in the MS switching to GAN mode. The MS then begins transferring packets via the GAN cell. The system and method also supports a packet-switched handover from the GAN cell to the GERAN/UTRAN cell.
