Control method, device, terminal and system for terminal access

Abstract

The invention discloses a control method, a device, a terminal and a system for terminal access, wherein the method comprises the following steps of: receiving a registration request from a terminal side; confirming an abnormal registration reason for the terminal side according to the registration request; uniting the abnormal registration reason due to invalid clip considered by the terminal as same refusing registration information, and returning the same refusing registration information to the terminal side; the registration information is refused due to an unsuitable cell in a location area. In the invention, when the terminal sends the registration request in a test network, a CS or PS service domain state can be directly avoided being arranged to be an illegal state, so that the terminal can resend the registration request, therefore, convenience is brought for terminal access, moreover, user experience can be greatly promoted.

Description

technical field [0001] The present invention relates to wireless and core network technologies in the communication field, in particular to a terminal access control method, device, terminal and system. Background technique [0002] In the prior art, since the public land mobile network (hereinafter referred to as PLMN) of the 3G experimental network is not written into the forbidden public land mobile network (FPLMN) list of the commercial subscriber identity module (hereinafter referred to as SIM / USIM) card, so the commercial SIM The user equipment of the / USIM card (hereinafter referred to as MS / UE) can initiate registration on the experimental network. When the MS / UE tries to perform Location Update (Location Update) or Routing Area Update (RAU) in the experimental network to register the circuit switched (hereinafter referred to as CS) or packet switched (hereinafter referred to as PS) domain, the experimental network It may return and use various registration exceptio...

AI Technical Summary

Problems solved by technology

The existing technical solutions are processed according to the specifications, such as 3GPP 24.008 agreement 4.4.4.7, when the location area update is rejected by the network as an illegal user, etc., the UE considers the card invalid and enters the restricted state; 3GPP 24.008 agreement 4.7.3.1.4 It is stipulated that when GPRS attach (GPRS attach) is rejected by the network as GPRS service not allowed (GPRS Service Not allowed), the UE considers that the packet switching (PS) domain card is invalid and enters the restricted state. In the prior art, the MS / UE will The information returned by the network sets the status of the CS or PS service domain of the SIM / USIM to illegal, which will cause the UE to be unable to make calls or surf the Internet, and cannot log in normally even if it returns to an available network

[0003] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: during the MS / UE registration request process, if the abnormal registration information returned by the network is received, the card CS or PS will be considered invalid, and the UE must be restarted. Normal use, which greatly affects user experience and terminal access
