Embodiment Construction

[0051] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0052] see Figure 4 , is a network architecture diagram of 2G / 3G in the embodiment of the present invention. In the network architecture, the 2G network and the 3G network belong to one CN, the network controller used by the 2G network is BSC, and the network controller used by the 3G network is RNC. Figure 4 The shown 2G / 3G network architecture and figure 1 The difference between the 2G / 3G network architecture shown is: figure 1 In the shown networking architecture, the RNC receives / receives signaling or service data streams with the CN based on the Iu interface, and the BSC receives / receives signaling or service data streams with the CN based on the A interface. Figure 4 In the shown networking architecture, a new type of Iur-g interface is defined between RNC and BSC, and based on the new type of Iur-g interface, the interaction of control sign...

Abstract

The invention discloses a method, a device and a system for switching between heterogeneous networks, and solves the problems of long wireless network switching time and low network switching success rate in the prior art. The method comprises the following steps that: a first network controller sends a network switching request to a second network controller of a second network to which a target cell belongs according to a measurement report sent by a user terminal in a first network to which the first network controller belongs; the first network controller receives a network switching command sent by the second network controller after determining that the user terminal is allowed to be accessed into the second network according to the network switching request; and the first network controller informs the user terminal to execute network switching according to the network switching command. Due to the adoption of the technical scheme of the invention, switching success rate between networks is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a handover method between heterogeneous networks, a network controller and a mobile communication network system. Background technique [0002] At present, the networking of the third-generation mobile communication network (3G network) and the second-generation mobile communication network (2G network) has been realized (subsequently using 2G / 3G to indicate the networking), the existing 2G / 3G network architecture Figure such as figure 1 shown in figure 1 Among them, the 2G network and the 3G network share the same CN (Center Network, core network), the network controller used by the 2G network is BSC (Base Station Controller, Base Station Controller), and the network controller used by the 3G network is RNC (Radio Network Controller, wireless network controller). In the prior art, the voice switching process for a dual-mode UE (user terminal) supporting 2G / 3G network is as...
