Embodiment Construction

[0019] The core idea of ​​the present invention is: in the case of a shared access network, that is, the user terminal always works on one carrier frequency, the CS domain and the PS domain of the core network are completely independent. That is to say, the PS network and CS network-related content is stored independently in the user terminal, including "current network", "prohibited PLMN list", "user-defined preferred PLMN and access technology sequence list", "operator Sequential list of preferred PLMNs and access technologies defined", etc. Therefore, the user terminal can be configured to select the CS network of one core network operator and the PS network of another core network operator automatically or manually, so that the user can obtain the CS service and PS service of different operator networks respectively.

[0020] figure 1 It shows that in the case of access network sharing, that is, in the case of wireless carrier frequency sharing, user terminals are respect...

Abstract

This invention discloses a method for accessing the core net by user terminals under the shared carrier frequency mode including: registering one or more than one PLMN marks and a CS / PS network corresponding to each PLMN mark in a user terminal, also including: a, the terminal selects a CS or PS network corresponding to the PLMN mark, b, the user terminal initiates an access request to the CS or PS, c, the terminal receives the access response of the network side to judge if the the access is successful, if so, it registers the PLMN mark of the current CS / PS network, if it fails, it selects another CS / PS network corresponding to the PLMN mark then returns to step B.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for a user terminal to access multiple core networks in a carrier frequency sharing mode. Background technique [0002] The mobile network is logically divided into core network and access network. The core network is further divided into circuit switching (CS) domain and packet switching (PS) domain. Different domains support user services in different ways. The CS domain provides circuit-switched connections, including entities such as Mobile Switching Center (MSC), Gateway Mobile Switching Center (GSMC), and Visitor Location Register (VLR); the PS domain provides packet-switched connections, including General Packet Radio Service (GPRS) services Node (SGSN), Gateway GPRS Support Node (GGSN) and other entities. The CS domain and the PS domain overlap, that is, include some public entities such as a home location register (HLR) and a service control point ...
