A network device within a data communication network includes a plurality of network interfaces, each programmed with a respective set of Address Resolution Protocol (ARP) routing entries for correlating network addresses with physical addresses. Each network interface is further programmed with an additional respective set of Longest Prefix Match (LPM) routing entries for correlating other network addresses with designated network interfaces to enable traffic matching one of the LPM routing entries to be forwarded to the appropriate designated network interface within the network device.


The present invention provides a device and method for performing device-to-device broadcast communication in a wireless communication network, wherein the method comprises the steps of: obtaining a row except a 1st row for device-to-device broadcast in a Walsh matrix; performing device-to-device broadcast based on a transmission pattern determined by the obtained row, wherein the transmission pattern is: performing the following operations based on each element in the row sequentially: when the element is a first value, performing broadcast transmission of a same data packet; when the element is a second value, performing broadcast reception. Compared with the prior art, the present invention overcomes semi-duplexing limitation and reduces in-band emission, thereby achieves a better system performance.


The invention discloses a method, at a primary e NB, of measurement enhancement on a turned-off small cell for dual connectivity, the method including: obtaining OFF-status information of the turned-off small cell from a secondary e NB; transmitting the OFF-status information to a UE; receiving a measurement report transmitted from the UE about the turned-off small cell; deciding to configure the UE with the dual connectivity; transmitting a request to the secondary e NB to set up the dual connectivity; and receiving an acknowledgement command of the secondary e NB, wherein when the acknowledgement command includes an acknowledgement of the secondary e NB for accepting setting up of the dual connectivity, the method further includes: transmitting RRC connection reconfiguration information to the UE, so that the UE accesses the secondary e NB and sets up the dual connectivity according to the reconfiguration information.

According to one aspect of the present invention, there is provided a method for serving a roaming mobile terminal in an HLR of a mobile communication system, wherein the method comprises steps of: a. determining location information of the mobile terminal based on a location update request of the mobile terminal as provided by an MSC of a country or region where the mobile terminal is located; b. when determining, based on location information of the mobile terminal, that the mobile terminal is in roaming and located in a predetermined roaming country or predetermined roaming region, generating a first Original-CSI of the mobile terminal, wherein a predetermined address entry in the first Original-CSI includes address information of an ARP proxy engine; c. transmitting the first Original-CSI to the MSC. According to the solution of the present invention, the user may simultaneously enjoy roaming services provided by its home service provider and the non-home service provider without changing the SIM card during roaming; besides, the user may select a service provider providing a roaming service at a lower price from among a plurality of service providers, thereby reducing the users roaming charge.


An apparatus includes an optical spatial-mode multiplexer having a plurality of optical inputs and an optical output and an optical spatial-mode filter end-connected to the optical output of the optical spatial-mode multiplexer. The optical spatial-mode filter is configured to end-connect to a multimode optical fiber having a set of optical propagation modes and is configured to pass the optical modes of the set whose velocities in the multimode optical fiber are within a selected range and to block remaining ones of the optical modes of the set.

Techniques are provided for anonymizing streamed data. In various embodiments data are anonymized by receiving a data element (pi, si) of a data stream, where Pi comprises an identifying portion and si, comprises associated sensitive information; assigning the identifying portion, pi, to a region Si, of a partitioned space S; encrypting the associated sensitive information si, as e{si); and storing the encrypted associated sensitive information e(si) in a list associated with the assigned region Si,. Optionally a permutation function randomizes the order that regions S1 S2,...., St in the partitioned space S are stored so that an adversary cannot obtain information by observing the data being stored in particular regions. The regions S1, S2,..., St have corresponding center points C1, C2, Ct, and a nearest center Ci, to pi is optionally determined. The encrypted associated sensitive information e(si) may be stored in a list associated with the nearest center Ci.


Method, configuration apparatus and computer readable medium to configure a plurality of cells belonging to a telecommunication network. Each cell is associated to an individual maximum transmit power allowed to transmit by the cell. Each cell is identified by a so called cell ID. The method comprises the following steps a step 301 of determining a number of cells in conflict and if the number of cells in conflict is above a predetermined threshold the method comprises the following steps a step 302 of decreasing the individual maximum transmit power associated to at least one of the cells in conflict.


Embodiments of the invention includean entity capable of serving a User Equipment UE for WLAN access to EPC, said entity configured to, for support of IMEI checking procedure for said access, perform at least one of:- request a 3GPP AAA Server to have IMEI checking performed- instruct the 3GPP AAA server on whether to continue or stop an access authorization procedure depending on the result of IMEI checking.
