摘要： Systems and methods are provided for supporting IPv4-IPv6 interworking of SIP messages in wireless networks and IMS networks. The interworking can be provided to smooth migration to an all-IPv6 IMS network by allowing the use and support of existing legacy IPv4 infrastructure. This functionality may be provided by a call session control function (CSCF) interposed between a user equipment (UE) and an IMS core network with interworking functionality or an interworking module. This device serves as a back-to-back user agent (B2BUA), allocates IP addresses from a pool, performs next-hop route protocol discovery, and maintains and stores information within the gateway as well as interworking and rewriting IP addresses within network messages, while proxying and maintaining sessions between the UE and the IMS core network. This allows for faster call setup, reduced capex/opex, improved debuggability, increased capacity and subscriber density by call processing distribution, and better user experience.
摘要翻译：提供了系统和方法，用于支持无线网络和IMS网络中SIP消息的IPv4-IPv6互通。可以通过允许使用和支持现有的传统IPv4基础设施来提供互通，以平滑地迁移到全IPv6 IMS网络。该功能可以由介于用户设备（UE）和具有互通功能的IMS核心网络或互通模块之间的呼叫会话控制功能（CSCF）提供。该设备作为背靠背用户代理（B2BUA），从池中分配IP地址，执行下一跳路由协议发现，并在网关内维护和存储信息，以及在网络消息内互通和重写IP地址同时代理和维护UE与IMS核心网之间的会话。这允许更快的呼叫建立，降低的资本支出/运算量，改进的可调性，通过呼叫处理分配增加容量和用户密度，以及更好的用户体验。

摘要： Systems and methods for providing dynamic changes to a packet flow in a communication network are described. The dynamic changes can include upgrading and downgrading quality of service (QoS), adapting the stream to a receiving device, modifying the stream to counter-act changes in an air interface, and modifying the stream to accommodate an inter-technology handover. These changes can be provided by inspecting packets at a gateway and setting up a proxy for multimedia stream packet flows. The proxy can coordinate transcoding to take place to change the stream. The gateway can also monitor conditions at the mobile node using a real time control protocol or other applicable protocols.

摘要： Systems and methods for managing packet flows in a communication network are provided. Packet information can be cached on different levels and used to avoid external queries. The cache information can also be correlated with other types of information, such as location information, to be able to serve that information quicker than if one or more external queries were to be made. A demux manager can provide routing and session setup, by routing packets that already have a session to the session manager and assigning packets to a session manager if they are not already assigned to a session. The tiered architecture also provides scalability to many users and minimizes delays even during high call volumes because the load can be distributed well across the gateway's resources.
摘要翻译：提供了在通信网络中管理分组流的系统和方法。数据包信息可以缓存在不同级别，用于避免外部查询。缓存信息还可以与诸如位置信息的其他类型的信息相关联，以便能够比如果要进行一个或多个外部查询更快地提供该信息。解复用器管理器可以通过将已经具有会话的分组路由到会话管理器并且将分组分配给会话管理器（如果它们尚未被分配给会话）来提供路由和会话建立。分层架构还为许多用户提供可扩展性，并且即使在高呼叫量期间也能最大程度地减少延迟，因为负载可以跨网关的资源分布良好。

摘要： Systems and methods are provided that allow the delivery of location based services within a communication network. The location information can be retrieved using information from the mobile node when the mobile node registers in the network. The location information can then be cached or stored in one or more places in the communication network and correlated with the mobile node's addressing information. If a request for location based services is received without location based information, the gateway can use location based information regarding the mobile node to provide location based services. The gateway can enable non IMS mobile nodes to obtain IMS location based services or incompatible mobile nodes to obtain location based services.
摘要翻译：提供了允许在通信网络内传送基于位置的服务的系统和方法。当移动节点在网络中注册时，可以使用来自移动节点的信息来检索位置信息。然后可以将位置信息缓存或存储在通信网络中的一个或多个位置并与移动节点的寻址信息相关联。如果接收到基于位置的服务的请求而没有基于位置的信息，则网关可以使用关于移动节点的基于位置的信息来提供基于位置的服务。网关可以使得非IMS移动节点能够获得基于IMS位置的服务或不兼容的移动节点以获得基于位置的服务。

摘要： Systems and methods to virtually and securely extend voice, data, and video services as well as applications on communication networks is provided. An access gateway device is used to provide interworking and extension of services from an enterprise network or a hosted enterprise network to a public network such as an IP Multimedia Subsystem (IMS) network. The access gateway device can also enable handoffs between an enterprise access point and the service provider's radio network while maintain the user's session. The access gateway can also extend services from the enterprise network to the service providers network and vice versa.

摘要： Systems and methods for integrating subscriber management and call control functionalities in a packet data network are provided. Subscriber management services include things such as tracking usage for billing, providing account information, and authorization of resources to a subscriber or user. Call control functionality includes setting up Session Initiation Protocol (SIP) call sessions for the exchange of data. SIP functionality is provided by a SIP server and subscriber management is provided by a Network Access Server (NAS), where the SIP functionality and NAS functionality are implemented on the same device. The combined device can maintain at least one database that maps information between the functionalities, so both functionalities may access or be alerted to the other's information.
