The embodiments of the present invention disclose a method for accessing a network, a terminal and a storage medium, which can determine the number of sets of radio frequency chips in the terminal when receiving the information of rejecting the access attempt fed back by the network side; when the number of sets of the radio frequency chips is When it is 1 set, determine the current state of use of the terminal; if the current state of use of the terminal is the Internet access state, determine that the terminal uses a target communication technology whose frequency is greater than the preset frequency; try to use the target communication technology to connect. into the network. By using the method provided by the present invention, the current user's usage status can be restored as soon as possible, and repeated switching of communication technologies to try to connect to the network can be prevented, thereby improving user experience.

Each of them will be described in detail below.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a method for accessing a network disclosed by an embodiment of the present invention. The method for interface push may include the following steps.

S101. Determine the number of sets of radio frequency chips in the terminal when receiving the information of rejecting the access attempt fed back by the network side;

It should be pointed out that the execution subject of this embodiment is a terminal.

In the embodiment of the present invention, the terminal may include various terminals such as a mobile phone, a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), and a mobile Internet device (Mobile Internet Device, MID), which are not limited in the embodiment of the present invention.

It should be pointed out that the application scenario of this method may be that the terminal interacts with the base station.

In addition, as shown in Figure 2, it should be pointed out that there are two reasons why the network refuses user attach. One is due to network reasons, such as the failure of attach caused by network interruption and system failure, and the other is due to user reasons. For example, the user does not subscribe to the GPRS function, which leads to the rejection of the network, and the user does not subscribe to roaming, which leads to the rejection of the local SGSN, and so on. We will determine the cause of the attach failure based on the cause value of the rejection message returned by the network. Usually, we think that the rejection message carrying the following cause value belongs to the user:

The more common user reasons cause value reasons are:

Cause#7 "GPRS services not allowed" GPRS services are not allowed;

Cause#8 "GPRS and non-GPRS services not allowed" GPRS and non-GPRS services not allowed

Cause#13 "Roaming not allowed in this LA" Roaming is not allowed in this location area;

Cause#14 "GPRS service not allowed in this PLMN" The current PLMN does not allow GPRS service;

Cause#15 "No suitable cells in location area" There are unmatched cells in this location area Uncommon user reasons cause value is:

Cause#3illegal MS. illegal MS;

Cause#6illegal ME. Illegal ME;

Cause#11PLMN not allowed.PLMN not allowed;

Cause#12location area not allowed. LA not allowed.

We consider rejection messages other than these user-cause values to be attributed to network-caused failures.

Some common network reasons cause value values:

Cause#17Network failureNetwork failure

Cause#111Protocol error, unspecified protocol error.

S102, when the number of sets of the radio frequency chip is 1 set, determine the current use state of the terminal;

Wherein, it can be understood that the current use state of the terminal includes: a state of making a call and a state of using network data.

In addition, it should be pointed out that the LTE (Long Term Evolution, Long Term Evolution) network does not support voice services, so two solutions of CSFB (Circuit Switched Fall Back, circuit domain fall back) voice fall and single card dual standby can be used. The CSFB voice fallback solution is that the mobile phone is usually in standby on the LTE network. When a call is received, the mobile phone is disconnected from the LTE network. The signal falls back to 2G/3G to complete the voice call, and the voice and 4G data services cannot be performed at the same time. The single-card dual-standby mobile phone is in 2G/3G and 4G standby at the same time, and the voice and 4G data services are carried out at the same time without affecting each other.

Therefore, it is understandable that when there is one set of radio frequency chips in the terminal, the terminal generally adopts the CSFB voice fallback technology to solve the problem of making calls and connecting to the LTE network; when there are two or more sets of radio frequency chips in the terminal, it can be used Single card dual standby solution.

S103. If the current use state of the terminal is the Internet access state, determine a target communication technology whose use frequency of the terminal is greater than a preset frequency;

It can be understood that, for example, if the terminal supports LTE, 3G and 2G communication technologies, the terminal will reside on the LTE network for a long time. Then LTE becomes a target communication technology with a frequency greater than a preset frequency.

It can be understood that, if it is determined that the terminal is running a browser or an application program that requires traffic, it means that the current use state of the terminal is the Internet access state.

In addition, optionally, if the current use state of the terminal is a call state, try to register with a 2G or 3G network to continue communication.

S104, searching for a target cell supporting the target communication technology;

A terminal may search for a cell that supports LTE or other communication technologies, and then attempt to camp on that cell.

S105. Attempt to access the target cell.

For example, when a user uses a terminal for online shopping, and the terminal resides in a certain LTE cell, if it receives a request to refuse an access attempt feedback from the network side, determine the number of sets of radio frequency chips in the terminal, if the number of sets is 1 set, then either use the RF chip to register 4G network to browse the web, or register 2G or 3G network to make calls. In this case, the two operations cannot coexist. At this time, it is determined whether a program requiring network traffic is currently running, and if so, it is determined that the current use state of the terminal is the Internet access state. Then determine the commonly used communication technology, and if it is the LTE technology, try to camp on the LTE network cell. You can set an upper limit for the number of attempts, such as 3 or 5 times. If the number of attempts exceeds the upper limit and still no dwell is successful, the attempt will be stopped. Keep trying until the position of the terminal changes.

In addition, optionally, after the attempt to access the target cell results in an access failure, the method further includes:

Count the number of failed attempts; when the number of failed attempts is greater than or equal to a preset number of times, determine an alternative communication technology; wherein, the alternative communication technology is another communication technology supported by the terminal; try to use the The alternative communication technology described above is used to access the network.

It can be understood that the terminal can sort the supported communication technologies according to the frequency of use. For example, LTE is the most frequently used, then LTE is the target communication technology, 3G is the second most frequently used, and 3G is the alternative communication technology.

In addition, optionally, if the access attempt fails, the number of failed attempts can be counted;

When the number of failed attempts is greater than or equal to the preset number of times, stop trying to access the target cell; when it is detected that the location of the terminal has changed, re-search for a cell that supports the target communication technology; 's district. That is to say, if the number of access failures is greater than the set upper limit, the attempt is stopped until the location of the terminal changes, and then the access is attempted again.

In other words, for example, if the terminal tries to access the target service network, but after the number of attempts is greater than the preset number of times, the access is still not successful, then the access attempt will be stopped. Identification) changes, then you can continue to try. Wherein, LAI includes Mobile Country Number (MCC), Mobile Network Number (MNC) and Location Area Code (LAC).

MCC (mobile country code)--Mobile country code, which consists of 3 digits, the coding range is 000-999 in decimal, which is the same as the MCC of IMSI. Here it indicates the country to which the GSM PLMN belongs. The resources of the MCC are provided by the ITU ( ITU) unified distribution, China's MCC is 460.

MNC (mobile network code)--mobile network number, which is composed of 2 numbers like MNC in IMSI, and the coding range is 00-99 in decimal. It identifies the mobile communication network (PLMN) to which the user belongs, because a country may It consists of more than one GSM PLMN, and the MNC is uniformly allocated by the relevant national telecommunications management departments. At present, there are two GSM networks in China. The MNCs of China Mobile and China Unicom are 00 and 01 respectively.

LAC(location area code)--location area code, used to identify a location area in the GSM mobile communication network, it is a hexadecimal code with a length of 2 bytes at most, in which "0000" and "FFFF" are reserved values, a location A zone may contain one or more cells. Its size is determined and adjusted by the operation department according to the PCH load situation and signaling link load situation in each area.

In addition, optionally, if there are at least two sets of radio frequency chips, the current usage status can be ignored and the network registration can be directly attempted. The method specifically includes:

When the number of sets of the radio frequency chips is at least two, it is determined that the terminal uses a target communication technology with a frequency greater than a preset frequency; searches for a target cell supporting the target communication technology; and attempts to access the target cell.

It can be seen from the above that, by implementing the technical solutions provided by the embodiments of the present invention, the number of sets of radio frequency chips in the terminal can be determined when the information of rejecting the access attempt fed back by the network side is received; when the number of sets of radio frequency chips is one set , determine the current use state of the terminal; if the current use state of the terminal is the Internet access state, determine a target communication technology with a frequency greater than a preset frequency used by the terminal; try to use the target communication technology to access the network. By using the method provided by the present invention, the current user's usage status can be restored as soon as possible, and repeated switching of communication technologies to try to connect to the network can be prevented, thereby improving user experience.
