    • Some embodiments provide methods for selecting tracking areas, including: receiving a plurality of messages from a plurality of base transceiver stations, each message including a list of tracking areas handled by the base transceiver station from which the message is received; performing domain name system queries for the tracking areas to retrieve information identifying serving gateways serving the tracking areas; based on the information identifying serving gateways, storing, in a local memory, a list of tracking area identities handled by each identified serving gateway; receiving a message from user equipment indicating a first tracking area; selecting at least one tracking area handled by a serving gateway serving the first tracking area based on the list of tracking areas handled by each identified serving gateway stored in the memory; and sending a tracking area identity list to the user equipment based on the selected at least one tracking area.
    • 一些实施例提供了用于选择跟踪区域的方法,包括:从多个基站收发台接收多个消息,每个消息包括由基站收发台处理的跟踪区域的列表,从该收发台接收该消息; 执行跟踪区域的域名系统查询以检索识别为跟踪区域服务的服务网关的信息; 基于识别服务网关的信息,在本地存储器中存储由每个识别的服务网关处理的跟踪区域标识的列表; 从用户设备接收指示第一跟踪区域的消息; 基于由存储在存储器中的每个识别的服务网关处理的跟踪区域的列表来选择由服务于第一跟踪区域的服务网关处理的至少一个跟踪区域; 以及基于所选择的至少一个跟踪区域向所述用户设备发送跟踪区域标识列表。

    • Systems and methods that provide a mechanism to relocate functions from one gateway to another gateway in a wireless communication network are disclosed. The gateway can implement an access service network (ASN) gateway in a WiMAX based network with a number of functionalities co-located on the gateway such as an authenticator, an anchor FA, an anchor DPF, a PMIP client, and a prepaid client. These functionalities can then be relocated from a first ASN gateway to a second ASN gateway. The proposed system and method reduces the messaging needed for the relocation and the number of components in the network, which can save capital and operating expenses. Additionally, the reduced messaging can reduce latency and delay in the process of relocating, which saves bandwidth and increases the level of service provided to the user.
    • 公开了提供将功能从无线通信网络中的一个网关重新定位到另一个网关的机制的系统和方法。 网关可以在基于WiMAX的网络中实现接入服务网络(ASN)网关,其中多个功能共同位于网关上,例如认证器,锚FA,锚DPF,PMIP客户端和预付费客户端。 然后可以将这些功能从第一ASN网关重新定位到第二ASN网关。 所提出的系统和方法减少了搬迁所需的消息和网络中的组件数量,从而可以节省资金和运营费用。 另外,减少的消息传送可以减少重定位过程中的延迟和延迟,这节省了带宽并增加了提供给用户的服务水平。
