摘要： A services gateway, which links client access by any technology to multiple service nodes, even if the client access technology is not directly compatible with the service node. The universal convergence border gateway (UCBG) utilizes the IP layer as a harmonizing layer to decouple standard services from their normally-associated access technologies. This is particularly advantageous with multifunction client devices because the best available wireless access technology can be used independently of the type of service being accessed. The UCBG uses a single encryption scheme to multiplex the traffic for various services with different characteristics into multiple data flows. The UCBG uses a single encryption scheme to converge the data flows to the client using a single control path without losing each traffic's characteristics such as QoS. The gateway also demultiplexes the converged traffic that it receives from the client in order for the data to reach the appropriate service node.
摘要翻译：即使客户端访问技术与服务节点不直接兼容，服务网关将任何技术的客户端访问链接到多个服务节点。通用融合边界网关（UCBG）利用IP层作为协调层，将标准业务与其常用的接入技术相分离。这对于多功能客户端设备是特别有利的，因为可以独立于被访问的服务类型来使用最佳可用无线接入技术。 UCBG使用单一加密方案将具有不同特征的各种服务的流量复用到多个数据流中。 UCBG使用单一加密方案，使用单个控制路径将数据流收敛到客户端，而不会丢失每个流量的特性，如QoS。网关还将从客户端接收的融合流量解复用，以便数据到达适当的服务节点。

摘要： A Stream Control Transmission Protocol (SCTP) cluster of multiple SCTP-servers is defined in such manner that some of the servers are assigned Active Role where others are assigned Standby Role with the purpose of ensuring uninterrupted SCTP-connections between the SCTP-cluster and any number of SCTP-clients. The Standby Servers use the same Internet Protocol (IP)-address(es) on the SCTP bound interfaces as their assigned Active Server. The Active Servers are effectively communicating to the SCTP-clients, where the Standby Servers are communicating to their assigned Active SCTP-Server using a separate backchannel TCP-connection. Over that backchannel connection the Standby Server receives regular updates from the Active Server. These updates hold enough information so that the Standby Server could locally simulate SCTP-negotiations and create SCTP-associations as if the SCTP-negotiations were performed directly with the SCTP-Clients. In this manner the Standby Servers are fully synchronized and ready in case of an Active Server failure to continue the SCTP-communications without any interruption. This handover does not involve any subsequent action from the SCTP-clients so that the SCTP-clients are unaware that such a handover took place.

摘要： An intelligent system and an algorithm at a packet network to reduce the amount of signaling in the radio access network and core network is defined. The system collects all the necessary information from the signaling exchange between the radio access network and the core network and takes the subscription characteristics and policy information into consideration to choose the optimal way of reducing the amount of signaling including selecting the optimal bearers for certain types of communications and paging selected area instead of the whole area for each device. The bearer selection algorithm takes several things as input to choose the optimal bearer to perform the task.

摘要： A gateway system employing a redirect mechanism at upper layer protocols over Transmission Control Protocol (TCP) in a packet network to circumvent problems related to alteration of TCP sequence number due to header enrichment. The gateway system increases the size of a redirect message by the size of the header enrichment and thereby brings TCP sequence number on both ends in sync despite adding the header enrichment information.

摘要： A proxy server provides an anchor point for access network changes in a wireless environment. One example embodiment uses the concept of proxy server in order to preserve a uniform connectivity to a gateway service node while roaming across different networks through a handover mechanism. In one embodiment, the client connects to a proxy server through one access network, and the proxy server manages and keeps track of the user session toward the gateway service node. The client then connects to any packet service network, including Internet, through the proxy. When the client moves from one network to another, it indicates the change to the proxy and proxy, using a handover mechanism, switches the access network while maintaining the user session toward the gateway service node. The handover mechanism involved is efficient, with minimal messaging overhead, and preserves the application layer IP address of the client. Therefore, the data connections do not suffer from interruptions due to roaming through different networks and the service is seamlessly continued.
摘要翻译：代理服务器为无线环境中的接入网络改变提供了一个锚点。一个示例性实施例使用代理服务器的概念，以便在通过切换机制跨越不同网络漫游时保持与网关服务节点的统一连接。在一个实施例中，客户端通过一个接入网络连接到代理服务器，并且代理服务器管理并跟踪到网关服务节点的用户会话。然后，客户端通过代理连接到任何分组服务网络，包括Internet。当客户端从一个网络移动到另一个网络时，它使用切换机制指示对代理和代理的改变，在维护用户会话到网关服务节点的同时切换接入网络。所涉及的切换机制是有效的，具有最少的消息传递开销，并且保留客户端的应用层IP地址。因此，数据连接不会因为通过不同的网络漫游而中断，服务无缝连续。

摘要： A method and apparatus for performing SIM-based authentication and authorization in a WLAN Internet Service Provider (WISP) network supporting the universal access method (UAM) of authentication and authorization enabling roaming for customers of mobile service providers onto said networks. In addition, the invention provides a secure way of authenticating the customer's client device to the mobile service provider's network by employing temporary credentials for authentication that provide privacy of the user's identity and prevent replay attacks. Finally, if the WISP network supports the ‘pass-through’ facility, the authentication can be done more securely and quickly.

摘要： An intelligent system and a method in a packet network to utilize the radio network resource and the core network resource in an optimized way so that more high priority, critical devices are granted access to the network while throttling the low priority, non-critical devices with the same given resource. The system collects all the necessary information from the signaling exchange between the radio access network and the core network and takes the device subscription characteristics and statically or dynamically defined throttling behavior rules into consideration to choose the optimal behavior to handle the requests from devices at any given time including deciding to reject the requests for certain types of devices under certain network conditions while granting the requests for other types of devices. This early throttling mechanism effectively increases the network resources, especially radio access network resources for high priority devices so that the quality of service does not change for those high priority devices even under network congestion condition.

摘要： Methods and systems for providing voice and date services in a femtocell wireless network. The proposed approach integrates IWLAN architecture into femtocell architecture by introducing a gateway to serve both IWLAN and femtocell users. The proposed approach handles the voice and data in a different way so that it enhances the data handling efficiency while re-using existing MSC investment. The proposed approach carries the data traffic from a femtocell base station to the gateway in native IP packet, instead of encapsulating them in 3G data, thus enhancing the efficiency and performance for the data traffic. The data traffic can then be sent to GGSN or directly to packet data network. The approach tunnels voice traffic to MSC through the gateway as in conventional Iu-CS approach.

摘要： According to one aspect, a mobility gateway device (MGW) receives a request from a wireless local area network (WLAN) controller of a WLAN for accessing the Internet or a packet core network, where the request is originated from a user equipment communicatively coupled to the WLAN. In response to the request, the MGW is configured to determine whether there is an active session associated with the UE over a wireless wide area network (WWAN). If so, the MGW assigns an IP address to the UE that was assigned to the UE during the active session of the WWAN. The assigned IP address is used by the UE to access the Internet or the packet core network over the WLAN.
