Abstract: In a telecommunications network system in which two translators are placed for the conversion of IP version 4 (IPv4)-version 6 (IPv6)-IPv4, one translator converts an IPv4 packet to an IPv6 packet by adding a prefix obtained from a prefix management server managing prefixes to an address contained in an IPv4 packet received from an IPv4 terminal and also converts an IPx6 packet to an IPv4 packet by removing a prefix from the address contained in the IPx6 packet received from the translator. According to the conversion table, the other translator converts the IPv6 packet received from the one translator to an IPv4 packet and an IPv4 packet received from the IPv4 server to an IPv6 packet, thus enhancing the transfer efficiency in the IPv6-IPv4 conversion network.

Abstract: Currently, the I.E.E.E. 802.21 specification allows multiple MIH (Media-Independent Handover) Users in a single MIH Function. However, the specification is not clear about how multiple MIH Users are supported by a single MIHF (MIH Function) under a constraint in which if there is only one MIH User is allowed to change the state of a particular link during a particular period of time. This document proposes a detailed architecture which allows for the co-existence of multiple MIH Users by introducing a link ownership scheme in the MIHF (MIH Function). The proposed link ownership scheme also supports the scenario in which the state of a link of a mobile node is changed by a network node by modifying the MIH_Register primitives in the I.E.E.E. 802.21 specification to signal the set of allocated links to a remote MIH User on the network node.

Abstract: The present invention relates to methods and arrangements in a multi-antenna radio communication system, in particular to methods and arrangements for improved multiple HARQ transmission in such systems. While HARQ transmission schemes, as known in the art, only can consider the fact whether or not a transmission attempt has been successful the present invention provides a HARQ retransmission scheme that considers the reception quality for already performed transmissions of a same data packet when selecting a resource allocation for necessary re-transmissions. Resource allocation for retransmissions is based on a pre-defined metric indicating a quality of the reception of the previous transmission attempts. Such a metric can be derived from a quality measure derived in the receiver unit, e.g. a CQI or CSI-based value, or an appropriate measure of the mutual information, e.g. the accumulated conditional mutual information (ACMI).
