摘要： The invention relates to a solution for providing a seamless handover. It is proposed to provide a first serving node (PDSN) in a first radio area and a second serving node (WSN) in a second radio area and an authentication unit being accessible by the first serving node and by the second serving node. Further it is proposed to run a delay timer for delaying a discarding of the first address by receiving a detach message from the user for detaching from the first serving node and to provide said address to the user located in the second radio area in case a handover procedure has been performed within the duration of the timer.

摘要： A system and method for monitoring and reporting a volume of data transferred between a Mobile Station (MS) and a data network during a data session. A Prepaid Server (PPS) maintains an MS account and informs a AAA Server of a predetermined volume of data that may be transferred during the session. A Packet Data Service Node (PDSN) sends interim accounting messages to the AAA Server which determines when the predetermined volume of data has been transferred, and notifies the PPS. When the account balance goes below a threshold volume, the data session is terminated. During handoff of the MS from a first PDSN to a second PDSN, a data tunnel is established between them. When the handoff is complete, the tunnel is torn down. The first PDSN reports the volume of data transferred through the tunnel to the second PDSN which reports the volume to the AAA Server.

摘要： An authentication server (e.g., AAA server) is described herein which is located in a CDMA2000 network and used to authenticate a user terminal that is connected to a non-CDMA2000 network. The authentication server receives an access request for authenticating the user terminal connected to the non-CDMA2000 network. Then, it obtains a root secret key shared between the user terminal and the CDMA2000 network and generates a GSM or UMTS-like authentication vector which is used to authenticate the user terminal according to a GSM or UMTS-like authentication method. The access of the terminal to the non-CDMA2000 network is granted upon successful authentication. According to embodiments of the invention, the non-CDMA2000 network can be a WLAN network, and the authentication methods used can be EAP SIP or EAP AKA. The present invention allows one to use authentication servers that were originally intended for WLAN-3GPP interworking scenarios also in WLAN-CDMA2000 network interworking.
摘要翻译：这里描述了位于CDMA2000网络中的认证服务器（例如，AAA服务器），用于认证连接到非CDMA2000网络的用户终端。认证服务器接收用于认证连接到非CDMA2000网络的用户终端的接入请求。然后，获得在用户终端和CDMA2000网络之间共享的根秘密密钥，并生成用于根据GSM或类似UMTS的认证方法认证用户终端的GSM或类似UMTS的认证向量。成功认证后，终端到非CDMA2000网络的接入。根据本发明的实施例，非CDMA2000网络可以是WLAN网络，所使用的认证方法可以是EAP SIP或EAP AKA。本发明允许在WLAN-CDMA2000网络互通中使用最初用于WLAN-3GPP互通场景的认证服务器。

摘要： A method and a packet data switching node such as for example a CDMA2000 Packet data Serving Node (PDSN) for assigning an IP address to a Mobile Node (MN) in a telecommunications network. The switching node and the MN are first involved in a discovery phase, then the MN sends a Protocol for Carrying Authentication for Network Access (PANA) Start-Answer message to the switching node with an indication that an IP address is requested. The indication may comprise, for example, a blank IP address. The switching node receives the PANA Start-Answer message and recognises the request for an IP address. It authenticates the MN, possibly in combination with an Authentication, Authorization, and Accounting (AAA) server, and if the authentication is successful, assigns a new IP address to the MN, and responds back to the MN with a PANA Bind-Request message comprising the assigned IP address.

摘要： A method in a Code Division Multiple Access (CDMA) 2000 packet data network of negotiating reporting mechanisms for accounting records, and sending accounting records from a Packet Data Service Node (PDSN) to an accounting server such as a Home Radius Server utilizing the Radius protocol. The PDSN sends an Access Request (AR) message to the accounting server, via any intermediate nodes, and includes (a) an Accounting Capability (AC) attribute indicating that the PDSN can accumulate a plurality of accounting records and send the accumulated accounting records in a container in a single message, and (b) an Accounting Handling (AH) attribute indicating a plurality of alternative reporting methods that trigger the PDSN to send a container. The Home Radius Server then sends an Access Accept (AA) message to the PDSN that (a) confirms that the Home Radius Server can receive accounting records in containers, and (b) indicates a preferred reporting method for triggering the PDSN to send a container. The PDSN then sends containers of accounting records to the Home Radius Server in accordance with the preferred reporting method. In an alternative embodiment, the PDSN may send containers of accounting records to the Home Radius Server at a pre-configured interval.

摘要： Techniques for implementing Multi-Protocol Label Switching (MPLS) directly in an SS7 protocol stack enable SS7 network layer protocols to interface, via MPLS, with literally any link layer technology. As a result, label switching can be used seamlessly throughout a collection of heterogeneous networks, including both IP-based and SS7-based networks. An exemplary method of routing SS7 data packets through a heterogeneous packet-switching network using MPLS includes the steps of: establishing an MPLS forwarding equivalence class (FEC), at least one element of the FEC being an SS7 destination; associating a label with the FEC at a first router in the heterogeneous packet switching network; attaching the label, at the first router, to a data packet belonging to the FEC; and forwarding the labeled data packet from the first router to a second router in the communications network. The SS7 destination can be, for example, a Destination Point Code (DPC), a Signaling Connection Control Part (SCCP) global title, or an SCCP subsystem number (SSN).
摘要翻译：在SS7协议栈中直接实现多协议标签交换（MPLS）的技术使SS7网络层协议能够通过MPLS与任何链路层技术进行接口。因此，可以在整个异构网络集合（包括基于IP和基于SS7的网络）中无缝地使用标签交换。通过使用MPLS的异构分组交换网络路由SS7数据分组的示例性方法包括以下步骤：建立MPLS转发等价类（FEC），所述FEC中的至少一个元素是SS7目的地; 在异构分组交换网络中的第一路由器处将标签与FEC相关联; 在第一路由器处附加标签到属于FEC的数据包; 以及将标记的数据分组从第一路由器转发到通信网络中的第二路由器。 SS7目的地可以是例如目的地点码（DPC），信令连接控制部分（SCCP）全局标题或SCCP子系统号（SSN）。
