    Abstract: System and method embodiments are provided for optimizing offloading wireless services to a WLAN in 3GPP-RAT mobility. The embodiments enable changing network priority based on changing network conditions. In an embodiment, a method in a user equipment (UE) for offloading wireless services to a wireless local area network (WLAN) in a Third Generation Partnership Project (3GPP) inter-radio access technology (RAT) handover includes receiving an access network discovery and selection function (ANDSF) policy from an ANDSF server, wherein the ANDSF policy comprises policy rules including a validity condition, wherein the receiving is performed during a procedure in which the UE conducts an inter-RAT handoff from a first 3GPP RAT to a second 3GPP RAT; comparing evaluation condition information for the second 3GPP RAT against the validity condition; and offloading a first wireless service to the WLAN in accordance with the ANDSF policy when the validity condition is satisfied.

    Abstract: Internet protocol (IP) address allocations in distributed EPC networks can be published to an IP address registry maintained at the central EPC entity in order to facilitate the routing of authentication authorization, and accounting (AAA) signaling of third party networks throughout the distributed EPC network architecture. The address allocations can be published directly to an address registry maintained by the central EPC entity, or indirectly via a cloud management server. Additionally, latencies associated with UE authentication in distributed EPC network architectures can be mitigated by triggering communication of the authentication or authorization profile upon reception of an update location request (ULR) message at the central EPC network entity.

    Abstract translation: 分布式EPC网络中的互联网协议（IP）地址分配可以发布到维护在中央EPC实体的IP地址注册，以便于分布式EPC网络中的第三方网络的认证授权和计费（AAA）信令的路由 建筑。 地址分配可以直接发布到由中央EPC实体维护的地址注册中心，或通过云管理服务器间接发布。 此外，通过在中央EPC网络实体接收到更新位置请求（ULR）消息时触发认证或授权简档的通信，可以减轻与分布式EPC网络架构中的UE认证相关联的延迟。
