Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for establishing a bearer.
Background
As EPC traffic grows, the traditional EPS gateways gradually create some constraints. User data stream processing is centralized at a PDN outlet gateway, so that the functions of gateway equipment are complex and the expandability is poor. The control plane of the gateway is highly coupled with the user plane, which is not favorable for the smooth evolution of the core network. The expansion demand frequency of the user plane is higher than that of the control plane, the tight coupling leads to synchronous expansion of the user plane of the control plane, and the updating period of the equipment is short, thus leading to composite cost increase. The network layer data forwarding is difficult to identify the user and Service characteristics, and can only forward according to the Quality Of Service (QoS) transmitted by the upper layer, which results in inefficient network resource utilization and difficulty in fine control Of data flow according to the user and Service characteristics. In addition, a large number of strategies require manual configuration, resulting in increased management complexity and high operation cost. Therefore, it is necessary to further separate the control function from the forwarding function in the packet domain gateway to meet the requirements of network development and market application.
Fig. 1 is a schematic diagram illustrating separation of a control Plane and a User Plane of a GW in a non-roaming scenario in the related art, and as shown in fig. 1, the architecture splits an S-GW/P-GW in an original EPS architecture into two types of functional network elements, namely, a Control Plane Function (CPF) and a User Plane Function (UPF). The CPF is responsible for the control plane functions of the S/P-GW, including functions of load sharing, selection of the UPF, allocation of IP addresses and tunnel identifiers, policy and charging control, and the like. The UPF includes a Serving Gateway User Plane Function (SUPF) and a Packet Data Network Gateway User Plane Function (PUPF), respectively corresponding to the User planes of the S-GW and the P-GW, and is responsible for the related functions of the User Plane of the S/P-GW, including functions of Data flow identification and deep Packet analysis, QoS processing and bearer binding, and caching of downlink paging Data. The user interface and the control interface which are butted are respectively corresponding to the CPF and the SUPF/PUPF, and the functions of the other corresponding interfaces are compared with the original EPS architecture.
After the GW control plane and the user plane are separated, a plurality of problems of the existing EPS gateway are solved, and the user plane is flexibly deployed to reduce traffic roundabout.
In the prior art, based on the fact that the CPF is definitely allocated in the current protocol and includes the address of the user for accessing the internet, the coupling established between the CPF and the UPF, hereinafter referred to as Sx connection, is established, the CPF and the UPF at both ends of each Sx connection are respectively identified by a Node ID, and the session/control message on the coupling carries the Node ID. The load reported by the UPF is the whole load based on the Node ID.
When there are multiple service processing units in the UPF and each service processing unit exposes an independent service address to the outside, the CPF needs to know not only the load of the entire UPF but also the load of each service processing unit in order to distribute the services uniformly in the nodes of each UPF.
Aiming at the problem that the load reported by the UPF is the whole load of the UPF and the load control effect on the UPF is poor in the prior art because the UPF-based processing units directly bind the addresses, a solution is not provided.
