The embodiment of the invention relates to a non-3GPP access network roaming attachment method, which comprises the steps of receiving a non-3GPP access network roaming attachment request; creating mobility management context and bearer management context; creating a GTP transmission tunnel between a home location data gateway and a first roaming location service gateway and an IP transmission path between a terminal and the first roaming location service gateway; and binding the GTP transmission tunnel and the IP transmission path. The embodiment of the invention also relates to a non-3GPP access network roaming attachment system, a network roaming quit method and a system thereof, and a roaming system. By using the embodiment of the invention, the non-3GPP access network can use the GTP-based roaming interface to realize roaming attachment and network roaming quit, so as to simplify the switch between the 3GPP access technology and the non-3GPP access technology, reduce investment cost of operators, and accelerate the implementation of non-3GPP access network application in the current network.

An embodiment of the invention provides a gateway equipment disaster tolerance method and communication equipment. The gateway equipment disaster tolerance method comprises the steps that: first access and mobile management equipment receives a business request of terminal equipment; the first access and mobile management equipment responds to the service request, determines that the first gatewaycontrol plane equipment fails, and selects a second gateway control plane equipment, wherein the first gateway control plane equipment is used for managing the session of the terminal equipment in the gateway user plane equipment; and the first access and mobility management equipment sends a first message to the second gateway control plane equipment, wherein the first message comprises first disaster recovery data corresponding to the terminal equipment, and the first disaster recovery data is used for the second gateway control plane equipment to recover a session of the terminal equipmentin the gateway user plane equipment according to the first disaster recovery data. By adopting the gateway equipment disaster tolerance method and the communication equipment of the invention, the complexity of session recovery can be simplified, the reliability of session recovery is improved, the resource utilization rate is improved, and the cost is reduced.

The present invention relates to a method for assigning unique identifiers to a mobility management entity in a core network of an SAE/LTE communication system as well as a method for implementing a mobility management entity in a core network of an SAE/LTE communication system. Further, the invention relates to a mobility management entity of a core network of an SAE/LTE communication system.

Disclosed in the present invention are a resource policy decision method and system in a roaming scenario, for improving the accuracy of the resources allocated to the user. The method includes: after having received an available resource query message from a mobility management and control function MMCF entity, a resource and admission control function RACF entity of a visited network acquiring degrade information of current service of a user from a resource and admission control platform, and according to a candidate access network list in the available resource query message, checking current availability of resource of each candidate access network in the candidate access network list, so as to obtain resource availability information of each candidate access network; the RACF entity of the visited network carrying out resource decision according to the degrade information, the resource availability information and user information of the user.
