An embodiment of the invention discloses a method for accessing a terminal to a network. The method comprises the steps of searching long term evolution (LTE) networks, and sending a joint registration request to one target LTE network that is searched; receiving a response result that is sent from the one searched target LTE network and is for the joint registration request; and if the response result that is sent from the one searched target LET network and is for the joint registration request only allows non-joint registration, searching a 2G / 3G network, and initiating a registration process to the searched 2G / 3G network. The invention also discloses an apparatus for accessing the terminal to the network. Through adoption of the method and apparatus, in an area that is covered by both the LTE network and the 2G / 3G network, when the terminal cannot realize joint registration or joint position update, the terminal is forced to switch to the 2G / 3G network, so as to enjoy the data service and voice service by using the 2G / 3G network.
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 access a network. Background technique [0002] The goal of LTE (English: Long Term Evolution, Chinese: Long Term Evolution of Universal Mobile Communication Technology) is to provide better data services, but it only implements the PS domain (data domain), but not the CS domain (voice domain). In order to support voice services, 3GPP (English: 3rd Generation Partnership Project, Chinese: Third Generation Partnership Project) proposed CSFB (English: Circuit Switched Fallback, Chinese: Circuit Domain Fallback) technology, that is, when the 2G / 3G wireless communication network and the LTE wireless communication network overlap In the deployed area, the 2G / 3G wireless communication network is used to provide voice services, and the LTE wireless communication network is used to provide data services. When the terminal resides on t...
