Embodiment 1

[0046] figure 2 The implementation process of the method for establishing a tunnel provided by Embodiment 1 of the present invention is shown, and the user equipment side is taken as an example to illustrate, and the details are as follows:

[0047] In step S201, the user equipment UE selects an IP address of a tunnel master control node from an internal preset cluster address pool.

[0048] Since the UE does not know which port of the NNI interface gateway is idle when sending a tunnel establishment request message, and a port can contain multiple network tunnel endpoints, so if there are many UEs, the NNI interface gateway cannot accurately select the network Tunnel endpoint (Network Tunnel Endpoint, NTE).

[0049] In this embodiment, the tunnel master control node TMN is responsible for selecting the network tunnel endpoint NTE according to the service flow and configuration principles, wherein the tunnel master control node TMN is located on the NNI interface gateway, an...

Embodiment 2

[0060] image 3 The implementation process of the method for establishing a tunnel provided by Embodiment 2 of the present invention is shown, and the user equipment side is taken as an example for illustration, and the details are as follows:

[0061] In step S301, the user equipment UE selects an IP address of a tunnel master control node from an internal preset cluster address pool.

[0062] In step S302, send a tunnel establishment request message to the tunnel master control node corresponding to the IP address of the tunnel master control node, so that the tunnel master control node allocates a network tunnel endpoint for the UE and returns the network tunnel IP address of the endpoint to the UE.

[0063] In step S303, if the IP address of the network tunnel endpoint sent by the tunnel master control node is not received within the preset time, then step S304 is executed; otherwise, step S305 is executed.

[0064] In this embodiment, the UE detects whether the IP addre...

Embodiment 3

[0071] Figure 4 The implementation process of the method for establishing a tunnel provided by Embodiment 3 of the present invention is shown, and the side of the tunnel master control node is taken as an example for illustration, and the details are as follows:

[0072] In step S401, a tunnel establishment request message sent by a user equipment UE is received.

[0073] In step S402, a network tunnel endpoint is allocated to the UE.

[0074] In this embodiment, the tunnel master control node allocates network tunnel endpoints to the UE according to locally stored service flows of all network tunnel endpoints and preset configuration principles.

[0075] Specifically, the network element list configured inside the tunnel master control node stores the working status information of all network tunnel endpoints NTE, and the working status information includes port quantity, port number, flow information, failure or not, priority and so on. The master control node needs to kn...

Abstract

The invention is suitable for the technical field of mobile communication, and provides a tunnel establishment method, UE (user equipment) and an NNI (Network Node Interface) gateway. The tunnel establishment method comprises the following steps: an IP (Internet Protocol) address of a tunnel master node is selected by the UE from the internal preset cluster address pool; a request message of the establishment of the tunnel is sent to a tunnel master node corresponding to the IP address of the tunnel master node, and the tunnel master node serves as a tunnel terminal point of the UE distribution network and returns the IP address of the tunnel terminal point of the network to the UE; the IP address of the tunnel terminal point of the network sent by the tunnel master node is received; and the tunnel is established according to the IP address of the tunnel terminal point of the network and the tunnel terminal point of the network. According to the tunnel establishment method provided by the invention, the scope of application is not related to the number of the tunnels, and load-balancing can be achieved in tunnel terminal point of each of the networks.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a method for establishing a tunnel, user equipment and an NNI interface gateway. Background technique [0002] The Long Term Evolution (LTE) project is an evolution of 3G, which started at the 3GPP meeting in Toronto in 2004. LTE is a transition between 3G and 4G technologies, and is the global standard of 3.9G. It improves and enhances the air access technology of 3G, adopts Orthogonal Frequency Division Multiplexing (OFDM) and multi-input The output antenna system (Multiple-Input Multiple-Out-put, MIMO) is the only standard for its wireless network evolution. Under the 20MHz spectrum bandwidth, it can provide the peak rate of downlink 326Mbit / s and uplink 86Mbit / s, which improves the performance of cell edge users, can increase cell capacity and reduce system delay. [0003] Compared with 3G, LTE has more technical advantages, which are embodied in: h...
