Abstract: An increase in communication load in a network due to increasing messages for requesting information is suppressed. When a message for requesting information and a response message thereto are sent and received between a communication device (N1-Nn) that is an information requester and an information provider (Nx) on a network (NW) via a communication device (1), the communication device (1) stores the information acquired from the response message in a response information storage section (4), and when any communication device requests at least part of the same information, a control section (5) creates a response message including the requested information and responds.
Abstract translation: 由于增加用于请求信息的消息，网络中的通信负载的增加被抑制。 当通过通信设备（1）在作为信息请求者的通信设备（N1-Nn）和网络（NW）上的信息提供者（Nx）之间发送和接收到用于请求信息和响应消息的消息时， 通信装置（1）将从响应消息获取的信息存储在响应信息存储部分（4）中，并且当任何通信装置请求至少部分相同信息时，控制部分（5）创建包括 请求信息并作出回应。

Abstract: A base station includes a storage unit stores a neighbour relation table and a processing unit. The processing unit receives service information of a neighbour cell to its own cell, the service information being transmitted by another base station forming the neighbour cell to the own cell, the service information including at least one of an information element indicating whether the another base station has a function of a wireless LAN (Local Area Network) base station and an information element indicating whether the neighbour cell is a cell for dynamically adding a communication capacity. The processing unit registers the service information of the neighbour cell with the neighbour relation table.
Abstract translation: 基站包括存储单元，存储相邻关系表和处理单元。 所述处理单元向其自己的小区接收相邻小区的服务信息，所述服务信息由形成所述相邻小区的另一基站发送到所述自身小区，所述服务信息包括指示所述另一基站 具有无线LAN（局域网）基站的功能和指示相邻小区是否是用于动态添加通信能力的小区的信息元素。 处理单元将相邻小区的服务信息与相邻关系表进行登记。
