摘要： An apparatus and method for performing Mobile/IP handoff between different access technologies. Associated with each access technology are two thresholds, a Low Water Mark and a High Water Mark. The method uses these water marks to its access technology selection in a particular environment. Using the method, a mobile node 102 remains on its preferred network when the signal strength on the preferred network (interface) is above the low water mark. When the signal strength on the preferred network drops below the high water mark, the method calculates the low water mark for the network. When the signal strength on the preferred network drops below the low water mark (LWM), the method initiates handoff to the next available network that meets certain conditions. The method initiates handoff back to the preferred network when the signal strength measurement on the preferred network is again above the high water mark.

摘要： A communication system provides for an expedited Mobile Internet Protocol handoff by allowing a mobile station that is engaged in a communication session with a first access network to obtain Internet Protocol connectivity information associated with a second access network via the first access network. A tunnel is then established between the mobile station and the second access network via the first access network based on the Internet Protocol connectivity information and the mobile station obtains Internet Protocol configuration parameters from the second access network via the established tunnel. By obtaining the Internet Protocol configuration parameters associated with the second access network via the first access network instead of waiting until an air interface connection has been established with the second access network, the mobile station may be more expeditiously handed off to the second access network in the event that such a handoff determination is made.

摘要： A wireless communication system that implements cell reselections selects a timing of a cell reselection in association with a mobile station (MS) by transferring, by a layer at least as high as Layer 3 to a cell reselection decision function residing in a layer lower than Layer 3, information indicating whether a present time is a more favorable time or a less favorable time for a cell reselection and initiating, by the cell reselection decision function, a cell reselection at a time based on the information received from the layer at least as high as Layer 3. In another embodiment of the invention, the transferred information may instead, or in addition, indicate a future time at which to perform a cell reselection. By selectively timing a cell reselection, an impact of a cell reselection on an application being executed by the MS is minimized.

摘要： A method includes sending a request to a user indicating options to modify a quality of experience for one or more application flows between a radio network and a mobile node used by the user. The request indicates the user should select one of the following: declining an option to upgrade an existing service to a new service able to support the one or more application flows with a higher quality of experience than supported by the existing service; or accepting an option to upgrade the existing service to the new service. In response to receiving an indication the user selected the option to upgrade the existing service, performing one or more actions to upgrade the existing service to the new service. The option to upgrade the existing service can include an option of receiving advertisements for the new service or paying extra for the new service.

摘要： A method and system for communicating header compression layer control messages. Header compression control messages are generated by a header compression layer and are sent through at least one link layer data packet by a link transport communications protocol layer to a remote receiver. The link transport communications protocol layer monitors receipt of link layer data packet acknowledgements that are received from the link transport communications protocol layer of the remote receiver for the at least one link layer data packet. The link transport communications protocol layer determines successful transmission of the header compression control message and provides, to the header compression layer, an indication of successful header compression control message transmission.

摘要： Various embodiments are described to address the need for an apparatus and method that improves link layer handoff by addressing the packet-loss problem existing today. An intermediate buffer management layer (IBML) (201, 211) is introduced below layer 3 of an OSI-based communications interface. The IBML buffers copies of OSI layer 3 packets being transmitted via lower layers (205, 215) of the interface and manages the buffer contents using indications the IBML receives from one or more of the lower layers. When the IBML receives an indication that a link layer hard handoff is proceeding, the IBML transfers the presently buffered packets to a corresponding IBML (202, 212) in the target communications interface. This sub-layer 3 buffer transfer enables the target communications interface to reduce packet-loss associated with the hard handoff.
摘要翻译：描述了各种实施例以解决对通过解决目前存在的分组丢失问题来改进链路层切换的装置和方法的需求。在基于OSI的通信接口的层3之下引入中间缓冲器管理层（IBAM）（201,211）。 IBML缓冲器通过接口的较低层（205,215）发送的OSI层3数据包的副本，并使用IBML从一个或多个较低层接收的指示来管理缓冲器内容。当IBML接收到链路层硬切换正在进行的指示时，IBML将当前缓存的分组传送到目标通信接口中的相应IBML（202,212）。该子层3缓冲器传送使得目标通信接口能够减少与硬切换相关联的分组丢失。
