摘要： At a transmitting end, a selector multiplexes a command and data inputted from different systems to generate a multiplexed signal string(s). An encoding portion determines an amplitude value of a current multilevel code according to predetermined encoding rules based on a detected symbol and the amplitude value of a multilevel code generated immediately before and generates a multilevel code string. A transmitting portion transmits the generated multilevel code string to a receiving end through a transmission path. A decoding portion of the receiving end decodes and reproduces the command and the data with an amplitude value of the multilevel code string outputted from a receiving portion and the amplitude value of the multilevel code immediately before received according to predetermined decoding rules. The decoding portion separately outputs the command and the data. This allows various types of information to be multiplexed and transmitted with small delay.

摘要： A discriminator capable of generating a multi-level signal with less restrictions is provided. In a discriminator D1, a wave-shaping circuit 3 shapes the waveform of one branched multi-level signal MS, according to a control signal CS from a control signal generator 10 so that a detector 4 that follows the wave-shaping circuit 3 can correctly detect a first reference level RL1. The detector 4 detects the first reference level RL1 from an output signal OS3 from the wave-shaping circuit 3. A reference level generator 5 generates a second reference level RL2 of the multi-level signal MS. A threshold generator 6 generates thresholds Th1, Th2, and Th3 as much as required according to the first and second reference levels RL1 and RL2. Comparators 82 to 84 compares the amplitude of the other branched multi-level signal MS with the thresholds Th1, Th2, and Th3. A control signal generator 10 generates a control signal CS according to the comparison results from the comparators 82 to 84. The above structured discriminator D1 enables the transmitting side to generate a multi-level signal with less restrictions.

摘要： When a mobile terminal transmitting/receiving a packet using a plurality of IP address types performs a handover to an access network (single address type connection network) permitting transmission/reception of a packet using a single IP address only, an IP address not permitted is unfortunately discarded at an access network as a handover destination. Disclosed is a technique configured so that a mobile terminal (UE 1) detecting a handover to the single address type connection network establishes a temporary connection with a mobility management gateway (PGW 5) and thereafter acquires an address of an ePDG 8 located at a core network and informs the ePDG of a communication state before the handover via a PDN using the temporary connection. The ePDG informs the PGW of the communication state of the UE before the handover. Thereby, the communication state of the UE before the handover is achieved with the PGW via the ePDG and the PDN.

摘要： The invention relates to a method for ensuring IP session continuity upon a handover of a mobile node to a non-3GPP network, wherein an ongoing IP session of the mobile node goes via a packet data network gateway. For non-3GPP networks it is necessary to discover a security gateway and to then establish the corresponding tunnels to the ePDG to form the new data path; a security tunnel between the mobile node and the security gateway, and an IP tunnel between the packet data network gateway and the security gateway. In order to prepare the handover to possible non-3GPP accesses, the two tunnels are pre-established, however maintained deactivated until their use is actually needed. Accordingly, when handing over to the non-3GPP network, the IP session may be continued without any significant interruption by activating the already established tunnels.

摘要： The present invention introduces a method for the network to optimize the route for user's local IP access, without affecting the access to operator's core network. With this mechanism, no excessive signalling is needed for the optimization. The present invention is also applicable to the corporate network that has multiple home NodeBs or home eNodeBs. Finer grain control on the services to be provided over different home NodeB or home eNodeB is also possible. Further, path optimization and continuation of the service upon handover can be controlled, and hence flexibility of the service can be secured.

摘要： A technique is disclosed, according to which a race condition between a PMIPv6 binding by a PBU message of PMIPv6 and a CMIPv6 binding by a BU message of CMIPv6 can be resolved. MN 200 has a plurality of radio communication interfaces, and a first interface is connected to MAG 220 of a home PMIPv6 domain 230, for instance. In case the connection of a second interface is changed from MAG 221 of a home PMIPv6 domain to AR 222 of a CMIPv6 domain 231, a BU message 262 is transmitted from the second interface to LMA/HA 250, and identification information of this BU message is notified to MAG from the first interface. By adding time information to this identification information and by transmitting it to LMA/HA, MAG can identify transmission time of the BU message (i.e. relative order with the other messages) from this time information.

摘要： Disclosed is a technique for surely supporting multihoming for a mobile terminal (mobile node) moving in a local mobility domain. A mobile node (MN) 11 connects via an IF 110 to a mobile access gateway (MAG) 102 that supports multihoming, and further attempts to connect via an IF 111 to a MAG 103 that does not support multihoming. Under these conditions, according to this technique, when the MN recognizes that the MAG 103 does not support multihoming, the MN notifies a local mobility domain that the MAG 103 does not support multihoming if connection with the MAG 103 is not yet established, and notifies the local mobility domain of information on a connection to a local mobility domain other than the MAG 103 (connection with the MAG 102) if the connection with the MAG 103 is already established.

摘要： A technique capable of improving the communication throughput while maintaining the interchangeability with a radio communication system or radio communication method employing carrier sense in a conventional multiple access system is disclosed and, on the basis of this technique, a radio communication terminal accommodating apparatus determines the allocation order of communication right permitting the occupation of a radio transmission medium with respect to each of a plurality of radio transmission terminals and transmits a multiple-polling signal 311 including information on this order to the plurality of radio communication terminals at an arbitrary transmission timing acquired through the carrier sense. Thus, each of communication right time periods (communication right time periods 312 to 314) for which the occupation of the radio transmission medium is permissible is allocated to each of the plurality of radio communication terminals. In addition, a time sufficiently shorter than a guard time (carrier sense time) in a conventional system is employed as a time interval between communication right time periods adjacent to each other.
