Problems solved by technology

If the user terminal equipment does not cross the location area, or the period for the terminal equipment to update its location is relatively long, then the existing method cannot transfer the user terminal equipment to other CN nodes quickly and effectively.

Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] In the present invention, according to the load status of each CN node in the CN node pool, it is determined that the load of the CN node needs to be reduced, and when its load is transferred to other CN nodes in the CN node pool, the CN node and the original CN node that need to reduce the load will move to the idle CN node. The user terminal equipment in the state initiates paging, and the corresponding user terminal equipment responds to the paging of the original CN node to initiate a location update, and then the original CN node transfers the corresponding user terminal equipment to other CN nodes in the CN node pool, that is, the target CN node, so that The user terminal equipment in the idle state can be transferred between CN nodes without waiting f...

Abstract

The invention relates to a method for reducing the load of core network node, which can confirm the CN node that needs reducing load based on the load condition of each CN node, wherein said method comprises: the needed CN node as original CN node confirms the transferred idle user terminal device and sends page message to the user terminal; the user terminal device receives the page message to send position refresh request to the original CN node; the original CN node receives the position refresh, to transfer the relative user terminal device to other CN nodes, to quickly transfer the idle user terminal device of high-load CN node to the low-load CN node, to reduce the overload probability of CN node, to improve the advantage of pool area.

Description

technical field [0001] The invention relates to core network (CN) pool technology, in particular to a method for reducing the load of core network nodes in the core network node pool. Background technique [0002] According to the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) standard, a radio access network (RAN, Radio Access Network) node can be connected to multiple core network (CN, Core Network) nodes to form a many-to-many correspondence . The RAN node may be a radio network controller (RNC, Radio Network Controller) or a base station controller (BSC, Basic Station Controller). The CN node in the CS domain is a Mobile Switching Center (MSC, Mobile Switching Centre), and the CN node in the PS domain is a Serving GPRS Support Node (SGSN, Serving GPRS Support Node). [0003] The concept of pool area is proposed in the 3GPP standard. The pool area refers to the area covered by multiple RAN nodes. When the user terminal equipment roams in t...
