摘要:
A communication system is provided which includes different kinds of base stations such as a macro base station and a femto base station. This system may execute a method for controlling unfavorably occurring interference due to such different kinds of base stations. In the method, the femto base station sends a femtocell interference indication (FII) report to the resource allocation control unit when user equipment is connected to the femto base station. The FII report contains a request for the allocation of resources to avoid interference. Then the resource allocation control unit establishes a femto interference coordination (FIC) zone according to the received FII report. The FIC zone indicates a particular region used to define resources allocated to the femto base station. The resource allocation control unit may be the macro base station or a self-organizing network (SON) server.

An apparatus and method for configuration and optimization of an Automatic Neighbor Relation (ANR) in a wireless communication system are provided. The method of configuring the ANR by a Base Station (BS) in the wireless communication system includes receiving a measurement report message for reporting a neighbor cell's signal quality from one or more User Equipments (UEs), determining a neighbor cell, reported from a UE in an area where a serving cell's signal quality is greater than a first reference value, as an Overlay Neighbor (ON), among neighbor cells reported using the measurement report message, and determining a neighbor cell, reported from a UE in an area where the serving cell's signal quality is less than a second reference value, as a Horizontal Neighbor (HN), among the neighbor cells reported using the measurement report message, wherein the second reference value is set to a value smaller than the first reference value.

A method of configuring and registering an Internet Protocol (IPv6) address in a wireless mobile communication system having a connection-oriented radio link is provided. In an IP configuration method without Duplicate Address Detection (DAD), a Mobile Station (MS) is allocated a unique Connection Identifier (CID) specific to the MS from a serving Base Station (BS), and the MS and BS configure the IPv6 address independently using a known network prefix, a Medium Access Control (MAC) address of the MS, and the allocated CID. The BS registers the configured IPv6 address to a HA on behalf of MS.
摘要:
A handover method of a mobile station (MS) in a mobile communication system having MSs and radio access stations (RASs), each of which includes an IEEE 802.16 standard-based medium access control (MAC) layer and an Internet protocol version 6 (IPv6)-based IP layer. The handover method includes the step of gathering IP network information of a neighbor RAS through a message exchange with a previous RAS. A target RAS for handover based on the gathered IP network information of the neighbor RAS is determined, after the target RAS is determined, the previous RAS tunnels data for targeting the MS to the target RAS, Then the tunneled data are received from the target RAS.
摘要:
A method for determining an execution time of a VHO between base stations having different wireless interfaces in handoff among IP-based wireless access networks. The method includes: computing an execution time period of the VHO using identification information of the base stations, types of handoff protocols, a method for transferring data among the base stations, and transmission/reception mode information of an MT; computing first RSS information using the computed time period, the first RSS information representing an RSS threshold value of a home base station based on which the handoff must be performed before a link from the MT to the home base station is down; and determining the execution time of the handoff, including an initialization process for determining to perform the handoff using the first RSS information and RSS information values of the base stations.

Disclosed is a symbol synchronization method in an OFDM-based communication system which includes multiple access nodes supporting wireless connection of terminals, supports multi-connection of each terminal for the access nodes and performs synchronization by means of a cyclic prefix. The symbol synchronization method includes monitoring connection of a new access node; setting a number of times by which the new access node transmits equal symbols and a number of times by which at least one existing access node transmits the equal symbols when the connection of the new access node is detected; transmitting the equal symbols by the determined number of times by each access node; and performing synchronization by means of the symbols received from the access nodes by the terminal.
