PROVIDING MULTIPLE LEVELS OF SERVICE FOR WIRELESS COMMUNICATION

摘要

Local breakout is provided by one or more nodes (e.g., a local access point and/or a local gateway) in a wireless network to facili-tate access to one or more local services. In conjunction with local break-out, multiple IP points of presence relating to different levels of service may be provided for an access point. For example, one point of presence may relate to a local service while another point of presence may relate to a core network service. IP point of presence may be identified for an over--the-air packet to indicate a termination point for the packet. Also, differ-ent mobility management functionality may be provided at different nodes in a system whereby mobility management for a given node may be pro-vided by a different node for different types of traffic. Thus, an access ter-minal may support multiple NAS instances. In addition, different types of paging may be provided for different types of traffic. Furthermore, mes-sages associated with one protocol may be carried over another protocol to reduce complexity in the system.
