摘要： A Packet Core Function (PCF) and method of consistently selecting a Packet Data Service Node (PDSN) from a plurality of PDSNs in a packet data network to host a data session for a Mobile Node (MN). In a first embodiment, a static lookup table in the PCF is used to associate a list of identifiers for MNs and a list of the plurality of PDSNs in the network. The PCF obtains an identifier for the MN and utilizes the lookup table and a hash function to associate the identifier for the MN with a PDSN. The PDSN is then selected by the PCF to host the data session for the MN. In another embodiment, the PCF also includes a cache timer and a cache memory that stores the identifier for the MN and the IP address of the selected PDSN for a predetermined time period following the handoff of the MN to another PCF. If the MN returns to the PCF within the predetermined period of time, the PCF reselects the same PDSN to host the data session. In another embodiment, following the initial selection of a PDSN to host the data session, the EP address of the PDSN is sent to the MN which then passes the IP address of the PDSN to any subsequent PCFs where the MN roams. A PDSN zone ID may be utilized in lieu of the fill IP address.
摘要翻译：分组核心功能（PCF）以及从分组数据网络中的多个PDSN中一致地选择分组数据业务节点（PDSN）的方法，以主动移动节点（MN）的数据会话。在第一实施例中，PCF中的静态查找表用于将MN的标识符列表和网络中的多个PDSN的列表相关联。 PCF获得MN的标识符并利用查找表和散列函数将MN的标识符与PDSN相关联。然后由PCF选择PDSN以主持MN的数据会话。在另一个实施例中，PCF还包括高速缓存定时器和高速缓存存储器，用于在MN切换到另一PCF之后的预定时间段内存储MN的标识符和所选择的PDSN的IP地址。如果MN在预定时间段内返回到PCF，则PCF重新选择相同的PDSN以主持数据会话。在另一个实施例中，在初始选择PDSN以主持数据会话之后，将PDSN的EP地址发送给MN，然后MN将PDSN的IP地址传递到MN漫游的任何后续PCF。可以使用PDSN区域ID来代替填充IP地址。

摘要： A decompressor, a compressor and methods in an Internet Protocol (IP) network for reporting cause of missing packets. A cause of unsuccessful reception or sending of a compressed packet addressed is reported to a compressor/decompressor node. The compressor/decompressor node decides or predicts if a decompression context associated with the decompressor is invalidated by analyzing the cause of the unsuccessful reception and, optionally, analyzing a re-initialization agreement between the compressor and the decompressor. In an optional embodiment of the present invention, the compressor/decompressor node use the decision or prediction to exchange information to reinitialize the decompression context associated with the decompressor. In a preferable embodiment of the present invention, the detection of the unsuccessful sending or reception is performed at a Medium Access (MAC) layer associated with the compressor/decompressor node.

摘要： A system and method for optimizing the use of packet-resources by releasing a hanging packet-data connection when a Mobile Station (MS) performs a power-down while involved in a dormant packet-data session. A Base Station Controller (BSC) sends a message to a Mobile Switching Center (MSC) indicating that the MS has powered down. The MSC determines that the packet-data session is dormant, and sends an instruction to the BSC in a class-0 connectionless transaction to release network resources associated with the packet-data session. The BSC then sends an instruction to a Packet Control Function (PCF) to tear down the associated resources, and the packet-data connection is released by a Packet Data Service Node (PDSN) in response to the tearing down of the resources by the PCF.

摘要： A method and Policy Decision Function node are provided for maintaining a multimedia session in an alive state for a mobile station following a release of a network attachment resulting from a handoff from a first Packet Data Node to a second Packet Data Node followed by a dormancy state of the mobile station. If both Packet Data Nodes are comprised into a same MultiMedia Domain, the Policy Decision Function informs an Application Function of the MultiMedia Domain that the multimedia session shall be maintained. Otherwise, if the two Packet Data Nodes are comprised into distinct MultiMedia Domains, a first Policy Decision Function, in addition to informing a first Application Function that the multimedia session shall be maintained, also fetches a context of the multimedia session. Further, the first Policy Decision Function transfers the context of the multimedia session to the first Packet Data Node, which in turn sends the context of the multimedia session to the second Packet Data Node. Subsequent to reactivation of the mobile station, a second Policy Decision Function transfers the context of the multimedia session from the second Packet Data Node to a second Application Function in a second MultiMedia Domain.

摘要： A method and a decompressor node in Internet Protocol (IP) network for fast change of IP Headers Compression (HC) mechanism are provided. A Mobile Station (MS) connected to a serving system uses a first IP HC mechanism therewith. Upon initiating handoff of the MS from the serving system to a target system, a second IP HC mechanism is chosen to be used with the target system. The second IP HC mechanism is initialized using information received at the target system from the serving system. In a preferred embodiment, the received information is a decompression context and the initialization of the second IP HC mechanism consists of translating the decompression context from the first IP HC mechanism to the second IP HC mechanism.

摘要： Methods, and Packet Data Service Node (PDSN) and a Base Station Controller (BSC) of a Code-Division Multiple Access 2000 (CDMA2000) network for exchanging Generic Routing Encapsulation (GRE) frames that contain downlink IP packets, wherein the frames also contain an identity of the IP flows on which they are to be mapped. The PDSN receives IP data packets destined to an IP address, identifies an IP flow on which the IP packets are to be mapped, encapsulates the IP data packets in GRE frames, and adds to each one of the GRE frames the IP flow Id on which the IP packets are to be mapped. The BSC receives GRE frames, identifies the identity of the IP flow in the GRE frames, determines the Quality of Service (QoS) associated with the identified IP flow, and acts to enforce the determined QoS for the identified IP flow.

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： The invention relates to an improved handoff method for mobile IP in a cdma2000 network. During handoff, the A10 connection between the Target PCF and the PDSN is pre-set-up, while the MS is still connected to a MSC, when the Target PCF receives the message from the Target BSC to set up the A8 connection. Furthermore, in the case of inter-PDSN handoff, a tunnel is established between the PDSNs, over which the PPP context eventually is transferred to the Target PDSN. The Target PDSN then sends a message to the MS triggering a re-registration with the HA. The Target PDSN takes over full responsibility for the MS when it receives the Mobile IP Result from the HA, and sends a message to the Serving PDSN to let the latter know that it can release all resources related to the MS.
