Abstract: A method, a device, and a system for offloading network traffic are provided, which are applied in the field of mobile communications. An offloading device located before a Serving General Packet Radio Service Support Node (SGSN) receives a data stream of a user sent by a base station, obtains an offloading policy of the user from the offloading device and/or obtains the offloading policy of the user from a policy server, and forwards the data stream according to the offloading policy. Accordingly, the offloading device can obtain the corresponding offloading policy according to the data stream sent by a forwarding plane, send a data stream of low value, low real-time performance requirement, or low priority to the Internet or another specific networks, and send a data stream of high value, high real-time performance requirement, or high priority to high-value devices, thereby reducing the networking cost.

Abstract: A method, a device and a system for combination of resource admission control are provided. The system includes the policy determination combination device and multiple bearer and transmission devices. The combination device combines functions and interfaces of two or multiple kinds of arbitrary policy determination devices in systems of different standards, and has multiple interfaces to be connected with the bearer and transmission devices, and selects the corresponding interface working protocol according to the type of bearer and transmission device. Multiple bearer and transmission devices are connected with the policy determination combination device by different interfaces. By setting policy determination combination device, the combination of policy determination devices is realized with a few changes to the current network. When there are multiple types of bearer and transmission devices in a management domain, the number of the policy determination devices can be efficiently reduced, and the cost of setting up the network and maintenance can be reduced. Also, it is propitious to collaborate and combine different standards and to improve speed of industrialization.

Abstract: The present invention discloses a method, system, and device for admission control and pertains to the communications field. The method includes: admitting a subscriber for watching a multicast video only if each multicast bandwidth management device has sufficient remaining bandwidth after receiving a multicast video request from the subscriber; refusing the subscriber for watching the multicast video if any multicast bandwidth management device has insufficient bandwidth and fails to borrow bandwidth from a unicast bandwidth management device; and after receiving a unicast video request from the subscriber, admitting the subscriber for watching a unicast video only if remaining unicast bandwidth corresponding to a multicast bandwidth management device in each level is sufficient, or else, refusing the subscriber for watching the unicast video. Through bandwidth negotiation between the unicast bandwidth management device and each multicast bandwidth management device, admission control is implemented.

Abstract: A method, device and system for managing resources in networks are provided, which relate to the field of data communication. The method includes the following steps. A resource manager (RM) sends a first request message according to a received resource request message, to request an access node (AN) to perform admission control. After receiving an admission control result indicating whether a resource requested by the resource request message is admitted, the RM sends a response message of the resource request message. Therefore, when multicast/unicast connection admission control (CAC) that supports shared bandwidth is realized, flow fusions of user line configuration between the AN and a broadband remote access system (BRAS, and policy distribution between a resource and admission control subsystem (RACS) and the BRAS are guaranteed; and sharing of bandwidth resources is realized to avoid waste of the bandwidth resources.

Abstract: The present disclosure relates to the field of communications, and discloses a method for determining path pre-congestion. The method is applicable to an Ethernet path. Pre-congestion is determined and flagged through an ingress node or an intermediate node in the Ethernet path, and a pre-congestion status indication packet is sent by an egress node to the ingress node or a policy server, so that the ingress node or the policy server obtains pre-congestion information of the Ethernet path, and notify an application function entity AF of performing admission control. When the method in the present disclosure is used, problems of packet loss and excessively long time delay caused by the conventional congestion control technology may be avoided, thereby ensuring user experience of existing services.

Abstract: A method of realizing network address translation (NAT) includes the following steps. An application function (AF) entity receives a message, and determines a signaling direction according to the message. The AF entity carries the signaling direction information in an access authorization request (AAR) message and sends the AAR message to a service-based policy decision function (SPDF) entity. The SPDF entity obtains a corresponding local domain address according to the signaling direction, and sends the obtained address to the AF entity. The AF entity sends the message according to the local domain address. An entity and a system of realizing NAT are also provided. By extending a message interacted between the AF entity and the SPDF entity and adding a field indicating a signaling direction, the SPDF entity is enabled to distinguish an uplink direction or a downlink direction of the message, for example, from an access side/a local core side to a core side/an opposite core side or from the core side/opposite core side to the access side/local core side, so as to realize an NAT control.

Abstract translation: 实现网络地址转换（NAT）的方法包括以下步骤： 应用功能（AF）实体接收消息，并根据消息确定信令方向。 AF实体在接入授权请求（AAR）消息中携带信令方向信息，并将AAR消息发送到基于服务的策略决策功能（SPDF）实体。 SPDF实体根据信令方向获取对应的本地域地址，并将获取的地址发送给AF实体。 AF实体根据本地域地址发送消息。 还提供了一个实体和一个实现NAT的系统。 通过扩展在AF实体和SPDF实体之间交互的消息并添加指示信令方向的字段，SPDF实体能够区分消息的上行方向或下行方向，例如从接入侧/本地 芯侧到核心侧/相对的芯侧或从核心侧/相对的核心侧到接入侧/本地核心侧，以实现NAT控制。
