Problems solved by technology

[0013] In the process of realizing the above-mentioned network search steps, the inventor found that there are at least the following problems in the prior art: when the user terminal is rejected by the network for the location update request on the grounds of #2, #3, and #6, the SIM card or USIM card If it is set to invalid, the user will be in a service-limited state and cannot receive or make calls unless the user terminal is restarted; after restarting, the location update request to the network may still be caused by #2, #3, #6 The location update request is rejected, which affects the normal use of the mobile phone by the user

Embodiment 1

[0029] Embodiments of the present invention provide a method for processing network rejection messages, such as figure 1 As shown, the method includes the following steps:

[0030] 101. Receive a response message rejecting a location update request.

[0031] After the user terminal sends a location update request to the current network, if the current network rejects the location update request, it returns a response message rejecting the location update request to the user terminal, and the response message includes a rejection reason value.

[0032] 102. Record the current network that rejects the location update request in a rejection list.

[0033] The user terminal no longer initiates a location update request to the network recorded in the deny list.

[0034] The rejection reason values ​​include: #2, #3, and #6 listed in Chapter 4.4.4.7 of 24.008 of the 3GPP specification. Wherein #2 is an unknown International Mobile Subscriber Identity (IMSI unknown in HLR) in the ...

Embodiment 2

[0038] An embodiment of the present invention provides a method for processing a network rejection message, such as image 3 As shown, the method includes the following steps:

[0039] 301. Clear the rejection list when the user terminal is turned on.

[0040] The rejection list in the embodiment of the present invention records the networks that reject the location update request initiated by the user terminal. The reason for the network to reject the location update request initiated by the user terminal complies with the three reasons #2, #3, and #6 listed in Chapter 4.4.4.7 of 24.008 of the 3GPP specification. The three reasons are: #2: (IMSI unknown in HLR); #3: (Illegal MS); #6: (Illegal ME). is recorded on the deny list. If the network to be connected to is recorded in the rejection list, the network to be connected to has rejected the location update request of the user terminal, and the user terminal will no longer initiate a location update request to the network....

Embodiment 3

[0054] An embodiment of the present invention provides a device for processing network rejection messages, such as Figure 4 As shown, the device includes: a message receiving unit 41 , a network recording unit 42 , a first request unit 43 , a second request unit 44 , and a list clearing unit 45 .

[0055] The list clearing unit 45 is used to clear the rejection list when the user terminal is turned on. The rejection list in the embodiment of the present invention records the networks that reject the location update request initiated by the user terminal. When the user terminal is about to connect to the network, it judges whether the network to be connected to is recorded in the rejection list in sequence according to the order of RPLMN, HPLMN, Preferred PLMN, and strong signal PLMN. If the network to be connected to is recorded in the rejection list, the network to be connected to has rejected the location update request of the user terminal, and the user terminal will not ...

Abstract

The embodiment of the invention discloses a method and a device for processing network reject messages, relating to the field of communication and improving the capability of processing abnormities of a user terminal. The method for network reject messages provided by the embodiment of the invention comprises the steps of: receiving a response message of a reject position updating request, wherein the response message contains reject reason values; and when the reject reasons represented by the reject reason values are internal mobile user identification code (IMSI unknown in HLR), and illegal mobile station (Illegal MS) or illegal mobile equipment (Illegal ME), recording the current network of the reject position updating request to a rejecting list so as to lead the user terminal not to issue the position updating request to a network initiating position in the reject list. When being in the communication systems, the embodiment of the invention leads the user terminal rejected by the network to be capable of still working normally, so that the capability of processing abnormities of the user terminal is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for processing network rejection messages. Background technique [0002] The 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) specifications have formulated numerous standards for network equipment suppliers and terminal manufacturers to refer to and follow. GSM, UMTS and other mobile communication systems' network equipment and terminal work processes all comply with the content of 3GPP specifications. [0003] The network search process stipulated in 23.022 of the 3GPP specification can be briefly described as the following four steps: [0004] 1. The user terminal searches for networks existing in the current environment. [0005] 2. Among the searched networks, according to RPLMN (Registered Public Land Mobile Network, registered public land mobile communication network), HPLMN (Home PLMN, belonging to public land mobile c...
