摘要： A base station of a code division, multiple access (CDMA) telecommunications system employs scheduling of data transmission signals to corresponding user transceivers in down-link channels of a data network. One or more user transceivers may be in communication with a base station within a cell, and each user may have a minimum data rate requirement. In accordance with the present invention, the scheduling of user data transmission follows the constraints that 1) each base station transmits to user transceivers one at a time, and 2) the base station uses full available power for the down-link channel when transmitting (for data networks only). Given a data network of users, the method of scheduling and data rates may be modeled in accordance with a linear programming problem optimized according to a predefined criterion. In addition, the present method may be employed in a hybrid CDMA/time-share system to reduce power of data channels in communication with user transceivers near the base station. A continuum of rates may be achieved based on the system signal to interference ratio (S/I). The error rate requirement of a user's down-link channel may be met provided the S/I of the channel is greater than a predetermined threshold value.

摘要： In a communication network (400), wireless access points (300) utilize one or more agents (302, 306) to support the operating needs of corresponding mobile stations. Pursuant to one approach, the agent supports translation of the mobile station's end-to-end protocol-based messages to Internet Protocol-based messages that are readily ported through an Internet Protocol-friendly communication system infrastructure that preferably eschews the use of network elements that rely upon unique and/or proprietary non-Internet Protocol interfaces. Pursuant to another approach the wireless access point is able to interact on a peer-to-peer basis with other wireless access points in order to facilitate, for example, handovers and other mobility management tasks.
摘要翻译： 在通信网络（400）中，无线接入点（300）利用一个或多个代理（302,306）来支持相应移动台的操作需要。 根据一种方法，代理支持将移动台的基于端到端协议的消息转换为基于因特网协议的消息，其易于通过互联网协议友好的通信系统基础设施移植，该基础设施优选地避免网络元件的使用， 依赖于唯一和/或专有的非互联网协议接口。 根据另一种方法，无线接入点能够在与其他无线接入点的对等的基础上进行交互，以便促进例如切换和其他移动性管理任务。

摘要： Mobile station information is exchanged between a plurality of distributed mobility agents (106, 108). The exchange is initiated by a mobility agent (106) associated with a last known network access point (110) that has communicated with the mobile station (114). The mobile station (114) is paged from at least one network access point using an available air interface technology to interface with the mobile station (114) and using the mobile station information. No centralized controller is used in the paging.

摘要： A method for prioritizing Mobile IP between PMIP and CMIP includes the steps of connecting a mobile device (118) to a communication network (102) and determining (308) if the network provides mobility control, such as the network being PMIP-enabled. When it is determined that the network provide mobility control, the mobility function is assigned (312) to the network and is therefore given priority over the mobility function provided by the mobile device. It can be determined (304) that the mobile station also includes a mobility control so that when the network is not PMIP-enabled the mobile station controls (314) layer 3 mobility and the Mobile IP function.

摘要： Various embodiments are described to enable improved inter-network/inter-technology handover of mobile devices. A network device (131, 132) collects dynamic information corresponding to mobile devices (101, 102), such as wireless measurement information at the device's location, and/or information corresponding to wireless network nodes (121-124), such loading levels/loading distributions. The network device then sends some or all of the dynamic information collected and/or statistical information generated from the dynamic information collected to a neighboring network information server (150) for access by other communication networks. By maintaining dynamic and/or statistical information in a neighboring network information server, such information can be made available to all the communication networks in a given region. One potential benefit to making this information available is improved inter-network handoff decision-making.

摘要： A method and apparatus for handing over a mobile station (106) from a serving base station (104a) to a target base station (104b) within a wireless communication system (100) is described. A session is established between the mobile station and the serving base station and it is determined that the mobile station is to be handed over from the serving base station to the target base station. The target base station notifies the serving base station of identifying data of the target base station and added to the identifying data is a message to be sent to mobile station regarding the handover of the mobile station. The serving base station sends the message including the identifying data to the mobile station and the mobile station is handed over from the serving base station to the target base station using the identifying data of the target base station.

摘要： A wireless access point (200), upon determining (101) that a need exists to support a communication need of a mobile station, acquires (102) a first Internet Protocol (IP) address and automatically transmits (103) a gratuitous Address Resolution Protocol message to a local router to thereby cause the latter to correlate the first IP address to a Medium Access Control address for the wireless access point. In a preferred embodiment the wireless access point can also automatically transmit a registration request to a remote network element (such as a Home Agent) that presents this first IP address as a care-of address to use in conjunction with another IP address that serves as a home address for the mobile station.
