Method for Realizing Terminal Actively Reporting Location Registration Message

Abstract

The present invention provides a method and device for a terminal to actively report a location registration message. In the method of the present invention, it is determined whether a system, where a terminal (a UE) camps, changes and whether registration area information changes, so as to determine whether to trigger the UE to actively report registration to the system currently being camped on, thereby solving the problem of the incapability of reporting a location registration message caused by that the registration area information is the same when the UE moves between a CDMA2000 1x network and an LTE network, improving the success rate of paging, and improving the user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for a terminal to actively report a location registration message when the registration area information of a Long Term Evolution (LTE) network and a CDMA network are the same. Background technique [0002] In the Circuit Switched Fallback (CSFB) solution provided by the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as: 3GPP), some parameters of the CDMA20001x system need to be configured in the Long Term Evolution (Long Term Evolution; referred to as: LTE) network system. It includes registration information such as System Identification (SID for short), Network Identification (NID for short), Registration zone Identification (REG_ZONEID for short), and these information are obtained directly from the CDMA20001x network. The SystemInformationBlockType8 (abbreviation: SIB8) system message will deliver SID, N...

Problems solved by technology

The existing message types that can trigger registration in the CDMA20001x network are: Timer-based, Power-up, Zone-based, Power-down, Parameter-change, Ordered, Distance-based, UserZone-based, EncryptionRe-syncrequired, BCMCRegistration , but none of these registration methods can solve the problem that when there is a mutual coverage area between the CDMA20001x network and the LTE network, and the CDMA20001x network parameters such as SID, NID, and REG_ZONE configured on the CDMA20001x network are the same as the CDMA20001x network parameters configured on the LTE network, the UE is configured by CDMA20001x When the single overlay network moves to the overlay network of LTE and CDMA20001x or the UE that has completed CSFB pre-registration on the LTE network, during the process of moving from the overlay network of LTE and CDMA20001x to the overlay network of CDMA20001x alone, the UE cannot report the location registration message in time, resulting in The problem of MSC paging failure
