    • A method, wireless service node, and wireless communication system, are provided to manage wireless service usage and service node migration in the wireless communication system. A registration request from a wireless device (108) is received. A charging session associated with the wireless device (108) is established with a billing server (124). Wireless service usage is associated with the wireless device (108). The wireless device (108) is determined to be migrating to a new wireless service node (114). Information associated with the current charging session is transferred to the new wireless service node (114). Following the transfer, the service usage information pertaining to the same session is maintained and transferred by the new wireless service node to the billing server at appropriate time intervals and as per dynamic rules set in the billing server.

    • 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.
    • 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。
