摘要： A method for determining a network optimization policy, an apparatus, and a system are provided. A network optimization device can process a performance parameter of a network and a service requirement of a target service flow by using a network optimization algorithm, to obtain a target network optimization policy, and can apply the target network optimization policy to the target service flow, to enable transmission performance of the target service flow to satisfy the service requirement. Because the network optimization device can automatically determine the network optimization policy based on the network optimization algorithm, efficiency of determining the network optimization policy is effectively improved. In addition, when determining the network optimization policy, the network optimization device further considers the performance parameter of the network. Therefore, the determined network optimization policy can adapt to a dynamic change of network performance. In other words, when the network performance dynamically changes, it can also be ensured that the transmission performance of the target service flow satisfies the service requirement.

摘要： A hybrid network communication method is disclosed. A gateway device receives a first association request of a multimode device through a first physical interface, where the first association request includes a MAC address of a second physical interface of the multimode device. The gateway device receives a second association request of the multimode device through a third physical interface, where the second association request includes a MAC address of a fourth physical interface of the multimode device. The gateway device obtains an IPv6 address of the multimode device, and records a first correspondence and a second correspondence. The first correspondence includes the IPv6 address of the multimode device, the MAC address of the second physical interface, and the first physical interface. The second correspondence includes the IPv6 address of the multimode device, the MAC address of the fourth physical interface, and the third physical interface. In this way, any physical interface may be selected based on the IPv6 address of the multimode device to access the multimode device without sensing a link-layer forwarding path. This improves flexibility and communication quality of a hybrid network.

摘要： The present invention provides a method for sending a trigger message, and a device. When a third-party application server AS needs to establish a connection with machine-to-machine communications user equipment M2M UE, the third-party AS sends a trigger trigger message to a device trigger application server DT-AS, where the trigger message includes at least an identifier of the machine-to-machine communications user equipment M2M UE. The DT-AS determines, according to the identifier of the M2M UE, whether the M2M UE has registered with a network at which the DT-AS is located, and if the M2M UE has registered with the network at which the DT-AS is located, sends the trigger message to the M2M UE, so as to implement that the DT-AS identifies the trigger message, so that the M2M UE establishes a connection with the third-party AS.

摘要： Method and system for setting up a bearer are disclosed. The bearer setup method includes these steps: a packet data network gateway (PGW) obtains first quality of service (QoS) information and a first bearer identifier (ID), and sets up a bearer between the PGW and a radio access network (RAN) according to the first QoS information, where the bearer is associated with the first bearer ID; the RAN sets up a radio bearer (RB) with a user equipment (UE) according to second QoS information associated with the first QoS information, where the RB is associated with a second bearer ID associated with the first bearer ID. According to the technical solution of the present invention, when the UE is connected to a serving gateway (SGW) through a serving general packet radio service support node (SGSN), the SGSN and the SGW set up a bearer between the UE and the PGW. Thus, resources of each network entity in a network are fully utilized.

摘要： A packet sending method and apparatus, and a storage medium are provided, and belong to the field of communications technologies. In the method, after receiving a first data packet from a second site, a first network device searches a stored flow table for a target flow entry. Each flow entry includes a flow identifier and a corresponding outbound interface identifier, and the target flow entry is created when a first site sends a reverse data flow of the first data packet to the second site. If the target flow entry is found, the first network device sends the first data packet through an interface corresponding to an outbound interface identifier in the target flow entry. It can be learned that only when the reverse data flow passes through the first network device, does the target flow entry exist in the flow table of the first network device and can the target flow entry be found, and therefore the first data packet is sent through the interface corresponding to the outbound interface identifier in the target flow entry. Therefore, in this application, it can be ensured that a packet sent and a packet received with respect to a same application pass through a same network device.
