摘要： A relay gateway apparatus (HandOver-Gateway (HO-GW) is provided between heterogeneous access networks (a WiMAX access network and a UMB access network). The HO-GW performs conversion of a movement control signal (an Inter-Access Gateway (AGW) handover control signal) and relay of communication data. When the relay is performed, user data from a correspondent node (CN) reaches a wireless terminal (mobile node (MN)) through a host agent (HA) of a core network, an access router ASN-GW, the HO-GW, and a base station eBS.

摘要： A transmission area is specified flexibly in accordance with the contents of a flow. An area identification number (SHOG) is specified for each interlaced stream of wireless base stations. The same flow is sent at the same timing (or substantially at the same timing) in the interlaced stream specified for the same SHOG. A wireless terminal determines a neighbor sector or a neighbor wireless base station sending the same flow, in accordance with information given from the wireless base stations, and receives and combines the flows.

摘要： In a wireless communications system operating according to CDMA or the like, when one terminal simultaneously performs communication using multiple wireless resources (e.g., multiple carriers), there was a problem that when it was attempted to guarantee network mobility by the same soft handoff system as in the case where communication was performed using only one wireless resource, efficiency suffered from the viewpoint of network forwarding load, processing load and wireless resource occupancy time. Soft handoff termination is judged and soft handoff is forcibly terminated according to whether or not the data rate obtained for all resources on the network side satisfies a requested rate, based on a reception state notification from a terminal concerning wireless resources. By performing this processing, the soft handoff period is shortened, sufficient received strength in the terminal is maintained and terminal mobility is guaranteed, while at the same time network forwarding load, terminal processing load and wireless resource occupancy time are suppressed to the absolute minimum.
摘要翻译： 在根据CDMA等操作的无线通信系统中，当一个终端同时使用多个无线资源（例如，多个载波）进行通信时，存在如下问题：当尝试通过相同的软切换系统来保证网络移动性时 在仅使用一个无线资源进行通信的情况下，从网络转发负载，处理负荷和无线资源占用时间的观点来看，效率受到影响。 根据来自有关无线资源的终端的接收状态通知，根据网络侧所有资源获得的数据速率是否满足请求速率，判断软切换终止，并强制终止软越区切换。 通过执行该处理，可以缩短软切换时段，维持终端的接收强度，确保终端移动性，同时将网络转发负载，终端处理负荷和无线资源占用时间抑制到绝对最小。

摘要： In a conventional system, there is a possibility that human errors are generated in setting registration information because a maintenance engineer manually enters registration information into a session reference network controller which integrally controls access terminals and base stations. To improve the system, session reference network controller a session reference network controller stores the number of access terminals, N, in advance. And, when a “base distance” setting request is received from an access terminal via a base station, the session reference network controller or an OAM (Operation, Administration and Maintenance) server determines a base station, which is one of a plurality of controlled base stations and is Nth nearest from the base station that has transmitted the setting request, and sets the distance between the base station, which has transmitted the setting request, and the base station, which is Nth nearest, as the “base distance”.

摘要： The present invention is to accommodate a large number of users required in a digital radio communication system and to prevent communication quality from deteriorating. The present invention is to prevent the occurrence of a delay by adding a process for restricting packet assignment for a call having low communication quality. When the average DRC value is equal to or smaller than a threshold, assigned slots are thinned out to improve communication quality for radio terminals close to cell boundaries and to increase the number of radio terminals accommodated. As a method for thinning out assigned slots, packets received from an upper level unit of a radio base station are, for example, discarded before transmission as long as the lowest limit sound quality is maintained. With this operation, the lowest limit sound quality is ensured.
