Embodiment 1

[0033] According to an embodiment of the present invention, an access control method is provided. The method can be applied to any kind of service (for example, location update, or voice call, or short message service, or others) performed by the UE and the CN in a mobile network with a mixed network of multiple access systems, and the method includes: The CN sends a notification message to the UE, wherein the UE supports at least two radio access technology types, and the notification message here carries the information of the UE's preferred radio access technology type. Thereafter, the UE receives the notification message and obtains information from it; the UE selects an access network to camp on according to the information.

[0034]It should be noted that if this process occurs during the location update process, before the CN sends a notification message to the UE, the UE can send a location update request message to the CN. The above notification message can be a locat...

Embodiment 2

[0048] According to an embodiment of the present invention, an access control method is provided. figure 2 is a flow chart of the access control method according to Embodiment 2 of the present invention, such as figure 2 As shown, the method includes the following steps S202 to S204:

[0049] In step S202, the RNC receives a notification message from the CN, wherein the notification message carries information about the preferred radio access technology type of the UE, and the UE supports at least two radio access technology types. Prior to this, the CN sends a notification message to the RNC.

[0050] In step S204, the RNC obtains information from the notification message, and controls the UE to camp on a corresponding access network according to the information. For example, the operation of controlling the UE to camp on the corresponding access network according to the information may be implemented in the following manner: the RNC judges whether the access network wher...

Abstract

The invention discloses an access control method, a core network and a wireless network controller. The method comprises the following steps: the core network sends a notification message to user equipment, wherein the user equipment at least supports two types of wireless access technologies; and the notification message carries the preferable wireless access technology type information of the user equipment. The invention achieves the effect of optimizing the network resource service efficiency during the process of hybrid networking by multiple wireless access technologies.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to an access control method, a core network, and a radio network controller (Radio Network Controller, RNC for short). Background technique [0002] The current mobile communication system is in the evolution process from the second generation (2G for short) to the third generation (3G for short), and the 3G system will continue to evolve in the future. The difference between mobile communication systems of different standards is mainly that the wireless access technologies adopted by the access network are different, and the core network (Core Net, CN for short) can be shared. [0003] In the same mobile operation network, there is a hybrid network of access networks of various standards. A multi-mode user equipment (User Equipment, referred to as UE) that supports multiple access standards can pass through multiple access networks and CNs in this network. conduct bu...
