Abstract: Mobility between access domains in an Internet Protocol (IP) network can be supported by introducing a so-called Mobility Manager (MM) that maintains (Sl) a database of currently attached devices and their current access domain location. The mobility manager may then detect (S2), for a device registered in the database, a change of access domain from a first access domain to a second access domain by monitoring connection maintenance signaling related to the considered device. The mobility manager should at least obtain an indication of such a change of access domain. In response to a detected change of access domain, the mobility manager arranges (S3) for a reconfiguration of the network to forward traffic destined to an IP address of the device in the first access domain to a new location in the second access domain. In this way, the mobility manager allows the device to keep its IP address when moving between access domains.
Abstract translation: 可以通过引入维护（S1）当前连接的设备的数据库及其当前访问域位置的所谓的移动管理器（MM）来支持互联网协议（IP）网络中的接入域之间的移动性。 然后，移动性管理器可以通过监视与所考虑的设备相关的连接维护信令来检测（S2）对于在数据库中注册的设备，将接入域从第一接入域改变到第二接入域。 移动管理员至少应该获得访问域这种更改的指示。 响应于检测到的接入域的改变，移动性管理器布置（S3）用于网络的重新配置，将转发到第一接入域中的设备的IP地址的业务转发到第二接入域中的新位置。 以这种方式，移动管理器允许设备在接入域之间移动时保持其IP地址。

Abstract: There are provided a method, a network system, and a router capable of decreasing the chance of VRM or VLM changes so as to reduce signaling, and consequently contributing to better scalability. The method is applied to mobility management used in an IP-based network system, which contains a plurality of access routers (AR), location managers (LM) and routing managers (RM), through which a mobile node (MN) transmits and receives information. According to the method, a visited routing manager (VRM) where the MN is currently located monitors the MN, an AR currently communicating with the MN discriminates whether or not the MN is moving out of its connectivity range, and the VRM discriminates whether or not the MN is moving out of its control range. Then, the method switches mobility management over from the current AR to a new AR in accordance with the discrimination results, and switches mobility management over from the current VRM to a new VRM in accordance with the discrimination result.

Abstract: The present invention relates to a system having a mobile host (1) which can attach to different access networks (3A, 3B) for carrying on an active communications session with a correspondent host (2). The mobile host (1) has an identifier (NAI) which is independent of the access network (3A, 3B) to which the mobile host (1) is attached, but is assigned a communications address(IP Address) for carrying on an active communications session with a correspondent host (2), which address changes for example depending on the access network (3A, 3B) to which the mobile host (1) is attached. The system has a database (UNS User Name Service) which registers the association of the mobile host identifier (NAI) and the current communications address (IP address) of the mobile host (1). The correspondent host (2) is informed of the identifier (NAI) of the mobile host (1) when an active communications session is first established between the mobile host (1) and the correspondent host (2), and the correspondent host (2) accesses the database (UNS) to determine the current communications address of the mobile host (1). In accordance with the present invention, the mobile host (1) is engaged in an active communications session: detects when the communications address (IP address) of the mobile host (1) changes, for example as a result of attachment of the mobile host (1) to a different access network (3A, 3B): and upon detection of such a change of the communications address (IP address), sends a message (HANDOVER MESSAGE) to the recorded correspondent host (2), the message containing the mobile host's (1) identifier (NAI). The correspondent host (2) then uses the identifier (NAI) to access the database (UNS) to obtain the changed communications address (IP address) of the mobile host (1). The invention also provides related methods and mobile hosts.
Abstract translation: 本发明涉及一种具有移动主机（1）的系统，该移动主机（1）可以附接到不同的接入网络（3A，3B），用于与通信主机（2）进行主动通信会话。 移动主机（1）具有独立于移动主机（1）所附接入的接入网络（3A，3B）的标识符（NAI），但被分配有用于进行活动的通信地址（IP地址） 与通信主机（2）的通信会话，其根据移动主机（1）所附加的接入网络（3A，3B）进行变址。 该系统具有登记移动主机标识符（NAI）与移动主机（1）的当前通信地址（IP地址）的关联的数据库（UNS用户名服务）。 当在移动主机（1）和对应主机（2）之间首次建立活动通信会话时，通信对方主机（2）被通知移动主机（1）的标识符（NAI），并且对应主机（2） ）访问数据库（UNS）以确定移动主机的当前通信地址（1）。 根据本发明，移动主机（1）参与活动通信会话：检测移动主机（1）的通信地址（IP地址）何时改变，例如作为移动主机 （1）到不同的接入网络（3A，3B）：在检测到通信地址（IP地址）的这种改变时，向所记录的通信主机（2）发送消息（HANDOVER MESSAGE），该消息包含 移动主机（1）标识符（NAI）。 通信主机（2）然后使用标识符（NAI）来访问数据库（UNS），以获得移动主机（1）的改变的通信地址（IP地址）。 本发明还提供了相关方法和移动主机。

Abstract: A switching node 3 for providing admission control in a network comprises a number of separate priority queues 6 for receiving packets having different priority levels. Priority levels 1 to n provide guaranteed delay services, priority levels n+1 to m provide guaranteed loss services, and priority level Pm+1 provides best effort service. Measuring means 51 to 5m continually measure the average bit rate entering each priority level buffer P1 to Pm, except the lowest Pm+1. When a request arrives with a kth priority level, the network capacities for priority levels l=k . . . Pm are calculated. For all choices of l, the measurements of traffic loads of levels l and higher are taken into account. These capacity requirements are necessary to guarantee the quality of service for all flows already admitted to the lower priority queues. These capacities are compared to the network capacity, and if there is sufficient capacity, the request is accepted. Otherwise, the request in rejected.

Abstract: In a wireless communications network, communication between a source node and a destination node is initiated following detection of a free channel, using a request and acknowledgement exchange. If the exchange fails, a request retry is performed after a randomly determined time period. The request and acknowledgement may include channel preferences based on the capabilities of the source and destination nodes.

Abstract: A mobile host can attach to different access networks 3A,3B for communication with a correspondent host 2. The mobile host has an identifier (NAI - network address identifier) independent of the access networks, but is assigned an IP address for communication with the correspondent host which can change according to the access network used. The correspondent host is informed of the NAI when communication is first established and uses it to access a database 7 (UNS - user name service) to determine the current IP address of the mobile. The mobile host detects when its IP address changes during active communication (e.g. due to a change of access network) and sends a handover message containing its NAI to the correspondent host. The correspondent host then uses the NAI to access the database to obtain the new IP address of the mobile. The handover message may also contain the new IP address itself.
