Problems solved by technology

The existing technical solutions are based on the specifications, but in the 3GPP specifications, various complex network environments in reality are not considered
According to the protocol 3GPP 24.008, at this time, the UE will set the CS (Circuit Switching) or PS (Packet Switching) of the SIM to illegal according to the information returned by the experimental network received, which will cause the UE to be unable to make calls or When surfing the Internet, even if you return to the available network, you cannot log in normally, because the SIM has been set to CS or PS and is invalid, and the UE will not reset the SIM status. You must restart the UE to use it normally, which will cause inconvenience to the user.

Embodiment Construction

[0015] In order to have a better understanding of the present invention, the specific implementation of the method of the present invention will be described in detail below.

[0016] In the present invention, it is assumed that in the 2G and 3G networks of the same PLMN, when the terminal performs location update or route update or service domain registration, the specific implementation of the method described in the present invention is as follows figure 1 shown, including the following steps:

[0017] Step 11: In the PLMN, when the UE attempts to perform location update or route update or service domain registration, the network returns a registration exception message to the UE;

[0018] Step 12: UE receives this message, and no longer invalidates the CS domain or PS domain when the PLMN is registered;

[0019] Step 13: Determine whether there are other available networks in the current RAT, if so, perform step 14, otherwise, perform step 15;

[0020] Step 14: Determine...

Abstract

This invention relates to a net-selection and register method for a double-mode terminal including: A, a user terminal selects a wireless access technology RAT network, a public land mobile net PLMN and CS domain or PS service domain to try the registration, B, when the user terminal receives the abnormal registration information fed back by the network, it does not design the CS or PS of said terminal (U) SIM invalid.

Description

technical field [0001] The invention relates to an access method of a mobile communication network, in particular to a processing technology when a terminal switches between different networks. Background technique [0002] Now 3G networks are gradually starting to be commercialized all over the world. There are more and more 2G and 3G coexistence networks. Dual-mode mobile phones and other dual-mode terminals (hereinafter collectively referred to as UE, that is, user equipment) are born and gradually commercialized. They can be used in 2G and 3G. Switch freely between 3G networks. Because the 3G network is not yet a mature commercial network, there are a large number of experimental networks. Because it is a trial network, the operator will not write the PLMN (public land mobile network) into the FPLMN of the SIM card (disable the public land mobile network), that is, the SIM can register with the trial network. When the UE tries to perform location or routing update and ...
