Abstract: Providing a multicast service includes maintaining multicast service information at an application server. The multicast service information describes a multicast service having an associated subscriber, and the multicast service is operable to deliver multicast content from a multicast source. A cell supporting a user device associated with the subscriber is determined, and creation of a bearer path for the multicast service is initiated. Delivery of the multicast content to the user device is enabled using the bearer path.

Abstract: Techniques and systems for server farm load balancing and resource allocation are disclosed. In one embodiment, a method of load balancing can include: arranging servers into service groups; receiving an access request with information related to a differentiation between the service groups; selecting one of the service groups based on a mapping comparison to the information; and selecting one of the servers within the selected service group based on a hardware utilization comparison. The servers can include GPRS (General Packet Radio Service) Gateway Support Node (GGSN) or Remote Authentication Dial In User Service (RADIUS) servers, for example. The information can include an Access Point Name (APN) or Calling Station ID, for example.

Abstract: A method is disclosed for authorizing a prepaid network service in a data network. A network end station issues a request for a prepaid network service. At a network node, a determination is made about whether a user associated with the end station is authorized to access the prepaid network service. Network traffic from the end station is forwarded to a service provider only when the user is authorized to use the prepaid network service. Specific embodiments provide message flows among a mobile station (102), gateway support node (106), router (110), and authentication server (130) that support providing prepaid services in a packet-switched network for mobile communication. In certain embodiments, a connection is held open for an end station while a prepaid quota value is refreshed at a portal, thereby reducing overhead and precluding the need to repeat user logon steps.

Abstract: In one embodiment, a method can include: (i) performing an initial authentication with a mobile device in an access gateway, the access gateway being a point of attachment; (ii) forwarding a first message from the mobile device to an edge proxy; (iii) receiving a second message from the edge proxy; and (iv) returning a modified version of the second message to the edge proxy for a final authentication of the mobile device.

Abstract: In one embodiment, a network application may offload stateful operations to a user-plane application. In one embodiment, the network application receives state information for a user device. The network application then sends the state information to a user-plane application, which can maintain the state information. The network application may then offload a stateful operation to the user-plane application. For example, the network application may have the user-plane application perform stateful operations. Also, the network application may use the state information maintained at the user-plane application for error recovery after the network application fails. For example, the network application may recover the state information from the user-plane application after failure.

Abstract: An apparatus for signaling information in a network environment is provided that includes an access gateway operable to establish one or more packet data protocol (PDP) links on behalf of an end user. The access gateway is operable to communicate a message associated with a change in quality of service, locale, or policy enforcement relating to a selected one of the PDP links to a client services packet gateway (CSPG). The CSPG responds to the message by providing an accounting command for the selected PDP link such that synchronization is achieved between accounting information and a state associated with the selected PDP link.

Abstract: A system for efficiently reauthenticating a client of a network. In a specific embodiment, the system includes an authentication server and a Security GateWay (SGW) in communication with the client. The SGW includes reauthentication information associated with the client. In a more specific embodiment, the authentication server includes an Authentication, Authorization, and Accounting (AAA) server. The SGW further includes one or more routines for employing the reauthentication information to reauthenticate the client. The AAA server performs initial authentication of the client to enable client access to the network, which yields the reauthentication information. The reauthentication information includes one or more keys and/or counters, such as an authorization key, an encryption key, and a master key, which is/are predetermined by the AAA server.

Abstract translation: 一种用于有效地重新验证网络客户端的系统。 在具体实施例中，系统包括与客户端通信的认证服务器和安全门禁（SGW）。 SGW包括与客户端相关联的重新认证信息。 在更具体的实施例中，认证服务器包括认证，授权和计费（AAA）服务器。 SGW还包括用于使用重新认证信息来重新认证客户端的一个或多个例程。 AAA服务器执行客户端的初始认证，以使客户端能够访问网络，从而产生重新认证信息。 重新认证信息包括由AAA服务器预先确定的一个或多个密钥和/或计数器，例如授权密钥，加密密钥和主密钥。
