Allocation method of tracking area list and network equipment

Abstract

The application discloses a tracking area list allocation method and network equipment, which relate to the technical field of wireless networks, and can reduce signaling interactions between UEs and wireless networks when moving within the coverage area of ​​the same tracking area list, and save wireless network resources. The method includes: during the process of user equipment UE attaching to the network, the network device allocates a first tracking area list for the UE, the first tracking area list includes at least two first tracking areas, and the at least two second tracking areas A tracking area has the same circuit domain fallback CSFB support capability; if the at least two first tracking areas both support CSFB, the network device instructs the UE to attach to the first standard network; if the at least two second If none of the tracking areas support CSFB, the network device instructs the UE to attach to the network of the second standard. The solution provided in this application is suitable for use when allocating a tracking area list for a UE.

Description

technical field [0001] The present application relates to the technical field of wireless networks, and in particular to a tracking area list allocation method and network equipment. Background technique [0002] Currently, in a network including a Long Term Evolution (LTE) network, a third generation mobile communication (The 3rd Generation Mobile Communication, 3G) network and / or a second generation mobile communication (The 2nd Generation Mobile Communication, 2G) network In the wireless network, the mobility management entity (MobilityManagement Entity, MME) allocates a tracking area list (TAList, TAL) containing multiple tracking areas (Tack Area, TA) to the UE according to the movement trajectory of the user equipment (UserEquipment, UE) . Since the UE's movement trajectory is uncertain, in the above tracking area list, it is possible that there are tracking areas that support Circuit Switched FallBack (CSFB) and tracking areas that do not support CSFB.

AI Technical Summary

Problems solved by technology

When the tracking area list allocated to UE11 includes both CSFB-supporting tracking area 12 and CSFB-unsupporting tracking area 13, and the two types of tracking areas are distributed alternately, UE11 is moving along the movement trajectory 15 in the above-mentioned hotspot area , it is necessary to cross the boundary between the tracking area 12 supporting CSFB and the tracking area 13 not supporting CSFB multiple times, so it is necessary to frequently initiate processes such as attach (attach) and tracking area update (Tack Area Update, TAU) to the wireless network, In order to update its own location, there is more signaling interaction between UE11 and the wireless network when moving within the coverage area of ​​the same tracking area list, which occupies more network resources
