Description

Information processing method and device and electronic equipment

Technical Field

The application belongs to the technical field of communication, and particularly relates to an information processing method and device and electronic equipment.

Background

It is known that a terminal must camp on a network in order to be able to function for its communication. One of the important links of network residence is to select public land mobile network PLMN, and then perform cell residence after selecting PLMN. At this time, random access can be initiated to perform specific data service transmission.

In the 4G network era, the existing solution is to preferentially camp on the LTE (long term evolution) network. However, the LTE network of the terminal (UE) under the current PLMN may not be available due to the temporary abnormality of the current network, and a policy is needed to ensure that the UE can continue to camp on the network. At present, although the packet switched PS service on the LTE network cannot be guaranteed, in order to guarantee the normal operation of the circuit switched CS service for the user, the UE should fall back to 2G or 3G. However, when the 2G or 3G signal quality of a certain location is very weak, the user terminal cannot continue to use the current PLMN to select the 2G or 3G network for camping, which may result in no service, i.e. the signal lattice is grey, and the user experience is very poor.

As can be seen from the above, existing information processing schemes that are not available for LTE networks have a problem that may result in an electronic device being out of service.

The information processing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

An embodiment of the present application provides an information processing method, as shown in fig. 1, including:

step 11: under the condition that a first condition is met, acquiring available Public Land Mobile Network (PLMN) except the PLMN currently registered by the electronic equipment;

wherein the meeting the first condition comprises at least one of: receiving Attach reject (Attach reject) information; a first number of tracking area TA update requests are sent and no TA accept (TA accept) information is received.

In this embodiment of the application, the obtaining an available PLMN except a public land mobile network PLMN currently registered by the electronic device when the first condition is satisfied may include: displaying a prompt option when the first condition is met; the prompt option comprises a first option for switching PLMN; and acquiring available PLMNs except the PLMN currently registered by the electronic equipment under the condition that the first option is selected. Therefore, the user requirements can be met more humanizedly and better.

Step 12: and residing in the Long Term Evolution (LTE) network according to the acquired available PLMN.

Specifically, the LTE network may reside according to the acquired available PLMN when the available PLMN is acquired; but not limited thereto.

In this embodiment of the present application, the camping on the long term evolution LTE network according to the obtained available PLMN includes: and searching the LTE network for residing according to the preset priority sequence of the available PLMN.

Therefore, the better LTE network can be ensured to reside as soon as possible.

The "searching for LTE network to camp on according to the preset priority order of the available PLMNs" may specifically include: circularly executing to search for the LTE network supporting the residence (namely, the available) according to the obtained available PLMN with higher priority; and until the LTE network supporting the residence is searched and the residence is carried out, or the LTE network supporting the residence is not searched, and the traversal of the available PLMN is completed. That is, the search is attempted from the highest-priority PLMN until the search is successful or the traversal is complete.

Therefore, the LTE network residence of the available PLMN with higher priority can be optimized.

The searched LTE network is a network meeting a second condition; the satisfying the second condition includes: the signal strength of the available PLMN corresponding to the LTE network is greater than a first threshold, and the available PLMN corresponding to the LTE network supports camping.

That is, the network satisfying the second condition is an LTE network where a signal is strong and where the LTE network can reside.

Further, the information processing method further includes: in the event that a third condition is satisfied, fallback to a 2G network or a 3G network using the currently registered PLMN; wherein the third condition comprises at least one of: not acquiring the available PLMN; no LTE networks supporting camping are searched under the available PLMNs.

Thus, the service of the electronic equipment can be guaranteed as much as possible.

In an embodiment of the present application, the information processing method further includes: before the first condition is met, sending locally stored first information of available PLMNs to a network device through an attachment request or a tracking area update request; receiving second information, fed back by the network equipment, of the available PLMN of the electronic equipment in the current area; updating the first information according to the second information; the acquiring available PLMNs other than the public land mobile network PLMN with which the electronic device is currently registered includes: and acquiring available PLMNs except the PLMN currently registered by the electronic equipment according to the updated first information.

Therefore, the method can ensure that the available PLMN can be acquired as quickly as possible.

Wherein, in the case that the first condition is satisfied, acquiring an available PLMN except a public land mobile network PLMN currently registered by the electronic device includes: acquiring available PLMNs except the PLMN currently registered by the electronic equipment under the condition that a first condition is met and the electronic equipment is determined to be continuously located in the TA range currently located within a first time period; and under the condition that the first condition is met and the electronic equipment is determined to move out of the range of the TA where the electronic equipment is located within the first time period, searching the resident cell at other TAs.

Therefore, the available PLMN can be accurately and quickly obtained as much as possible; and repeated searching in an invalid TA range can be avoided, and the purpose of continuously residing in the LTE network is achieved. The other TAs may be specifically other TAs than the current TA.

Further, before determining that the electronic device continues to be within the current TA range for the first time period, or determining that the electronic device moves out of the current TA range for the first time period, the method further includes: the method comprises the steps of obtaining TA information of the electronic equipment at present, and obtaining movement trend information of the electronic equipment according to first reference information; according to the current TA information and the moving trend information of the electronic equipment, determining that the electronic equipment is continuously located in the current TA range within a first time period, or moving out of the current TA range; wherein the first reference information includes: at least one of gravity sensing information of the electronic device, distance information between the electronic device and the network device, and positioning information of the electronic device.

Therefore, whether the electronic equipment moves out of the current TA within a short time can be accurately determined, so that the electronic equipment can better reside in the LTE network in the following period.

For example, the electronic device takes the terminal UE as an example, the first information and the second information take a list form as an example, and the first number may be 5 times as an example.

In view of the above technical problems, an embodiment of the present application provides an information processing method, which may be specifically implemented as a method for continuously residing in an LTE network, so as to ensure that when an abnormality occurs in the LTE network of a current PLMN, the LTE network is continuously residing in by selecting PLMNs in other PLMN lists or disabling a current TA (tracking area), and thus, a problem that a PLMN falls back to 2G or 3G but cannot reside in a weak signal range before being continuously used, which may cause no service, is avoided.

The scheme provided by the embodiment of the application mainly relates to:

1. before the network becomes abnormal (i.e. the first condition is met), the UE may send a list of available PLMNs (corresponding to the first information) that carries local storage, which may be referred to as a Requested PLMN, to the network (corresponding to the network device) once each time the UE is able to perform an Attach request or TAU request procedure normally; the network then issues a list of all available and unavailable PLMNs of the UE in the current area, namely Allowed PLMNs (corresponding to the second information above) and Rejected PLMNs. The UE then saves this list locally, updates the previous PLMN list (corresponding to the first information), but does not update the PLMN list in the global subscriber identity module USIM card.

2. When for some reason the LTE network on the currently registered PLMN is not available, it is not hurry to fall back to 2G or 3G, but instead searches the LTE network again according to the priority (in particular, the order of PLMNs) according to the PLMNs stored in the local Allowed PLMN list by the UE. Specifically, the LTE network is searched for camping according to the preset priority order of the available PLMNs.

3. Before searching for the LTE network by the other PLMNs, the user may be notified in a terminal pop-up interface to select whether the current PLMN falls back to 2G or 3G or selects to change the other PLMNs to continue selecting the LTE network (corresponding to the above-mentioned display prompting option), and prompt the user for a time or a result that may be waited for.

4. When the UE is determined to be about to leave the tracking area (i.e., the tracking area TA), the TA is added to the forbidden list, and a cell suitable for camping is searched in other TAs, so that the UE can camp quickly. Corresponding to the above, in case that the first condition is satisfied and it is determined that the electronic device moves out of (i.e. does not continue to be in) the current TA range for the first time period, the camping cell is searched for in other TAs (ranges).

The present solution is specifically exemplified below.

For example, one:

the principle of this example is: before the network becomes abnormal (i.e. the first condition is satisfied), each time the UE is able to perform Attach request or TAU request normally, the UE sends a list carrying locally stored available PLMNs, which may be referred to as Requested PLMNs, to the network, and then the network issues a list of all available and unavailable PLMNs, i.e. Allowed PLMNs and Requested PLMNs, of the UE in the current area. The UE then saves this list locally, updates the previous PLMN list, but does not update the PLMN list in the USIM card.

When the user camps on the LTE network using the selected PLMN (i.e., the registered PLMN before the network anomaly, which may correspond to the currently registered PLMN described above), but the current LTE network is unavailable for some reason (e.g., attach Request (corresponding to receiving attach reject information) or no response from the network after 5 TAU requests (corresponding to sending the first number of tracking area TA update requests and not receiving TA accept information)), the LTE network is re-searched according to the priority level of the PLMN stored locally Allowed PLMN by the UE.

Specifically, this example provides a scheme for continuing to camp on an LTE network based on PLMN selection, including:

operation 1. the UE locally maintains a PLMN list including Allowed PLMNs and Rejected PLMNs.

Operation 2. the list maintenance rule of operation 1: before the network is abnormal, the UE sends a list carrying locally stored available PLMNs, called Requested PLMNs, to the network once at each attach request and TAU request, and the list is composed according to the PLMNs stored in the USIM card. The network then issues a list of all available and unavailable PLMNs, i.e., Allowed PLMNs and Rejected PLMNs, of the UE in the current area. The UE then stores this list locally and updates the previous list (i.e., PLMN list).

Operation 3. the user camps on the LTE network according to the selected PLMN (i.e., the registered PLMN before the network anomaly).

Operation 4. when the UE receives Attach reject Attach Request or the network does not respond after the UE sends TAU Request 5 times, the UE checks the local Allowed PLMN list. If there is an available PLMN in the Allowed PLMN list (i.e., the available PLMN is acquired), performing step 5; otherwise (i.e., the available PLMN is not acquired), operation 6 is performed.

And operation 5, selecting the high-priority PLMN to reside in the LTE network from the Allowed PLMN list set. When the signal strength of the selected PLMN is not sufficient (i.e. less than or equal to the first threshold) or the selected PLMN cannot camp on LTE (i.e. does not support camping, such as current area is not available, network does not support, network rejects, etc.), the next PLMN in the list is selected in turn until no PLMN is selectable. And when the selected PLMN can reside in the LTE network, the process is ended. When all attempts to camp on the LTE network by the PLMN of the Allowed PLMN list are completed, and LTE camping is still not successfully performed, operation 6 is performed. Corresponding to the loop execution, searching for an LTE network supporting the residence (namely, the available) according to the obtained available PLMN with higher priority; and until the LTE network supporting the residence is searched and the residence is carried out, or the LTE network supporting the residence is not searched, and the traversal of the available PLMN is completed. And under the condition that the available PLMN is not acquired, using the current registered PLMN to fall back to a 2G network or a 3G network.

Operation 6. fall back to the 2G or 3G network using the selected PLMN in operation 3 (i.e. the PLMN before the network anomaly), and the process ends.

Specifically, the process of this exemplary embodiment can be shown in fig. 2, and includes:

step 21: starting;

step 22: when the UE normally resides in the network, the UE sends a Requested PLMN to the network every time an Attach request or a TAU request;

step 23: the network sends the Allowed PLMN and the Rejected PLMN to the UE;

step 24: judging whether the network is abnormal, if so, entering a step 26, and if not, entering a step 25;

step 25: continuing to reside in the LTE network under the PLMN, and entering step 212;

step 26: judging whether a local Allowed PLMN list is available, if so, entering step 28, otherwise, entering step 27;

step 27: dropping back 2G or 3G using the original PLMN (i.e. the PLMN registered before the network anomaly), and entering step 212;

step 28: selecting the high-priority PLMN in the Allowed PLMN list in sequence, and entering step 29;

step 29: judging whether LTE can be resided under the high-priority PLMN, if so, entering step 210, and if not, entering step 211;

step 210: residing LTE under the high priority PLMN, and entering step 212;

step 211: judging whether the available PLMN exists in the Allowed PLMN list, if so, returning to the step 28, otherwise, entering the step 27;

step 212: and (6) ending.

From the above, the scheme of this example includes: when the LTE network is unavailable at a certain time, the PLMN is not urgently used to fall back to 2G or 3G, but other PLMNs are selected in the PLMN list to continue to camp on the LTE network.

Further, in the solution of this example, in the process of residing in the LTE network in this example, operations of a human-computer interaction interface may be simultaneously accompanied, and specifically, the operations may include:

operation 1. after operation 4 above in this example, an interface may pop up to prompt the user (corresponding to the display prompt option above), as shown in fig. 3: "currently 4G has no network, please choose to continue to surf the internet", "continue to search for 4G network (corresponding to the first option above) using other PLMN", and "return to 2G or 3G network using the PLMN". If the user selects "continue searching for 4G network using other PLMN", the following operation 2 of this example is performed; otherwise, the following operation 3 of the present example is performed.

Operation 2. switch the interface and pop up as shown in fig. 4 "would be waiting a period of time, if could continue to search for 4G network mode currently for using other PLMNs? "," determine ", and" cancel ". If the user clicks "ok," the web search proceeds as in operations 5 and 6 above in this example. Further, if the web search is successful, there may be a pop-up window or an interface prompt for the web search success, such as shown in fig. 5: "successfully use other PLMNs to camp on the 4G network (i.e., LTE network)"; if the search for the 4G network using the other PLMN is unsuccessful, an interface prompt may also be performed, such as shown in fig. 6: apology, no other PLMN is available for the local 4G network. If "cancel" is clicked, the following operation 3 of the present example is performed.

Operation 3. if no selection is made to search for a 4G network using another PLMN, the terminal will drop back to the 2G or 3G network camping using the current PLMN (corresponding to the currently registered PLMN described above).

In conclusion, the scheme of the example can enhance the user experience; when the current 4G network is unavailable due to network abnormality and other reasons, a user selects a subsequent network searching mode by using other PLMN lists and through interface interaction, and the following are avoided to a certain extent: the 2G or 3G network is directly dropped, but the local 2G or 3G network has poor signal quality, resulting in the phenomenon that the user terminal is finally out of service. In addition, when the UE can normally register the network each time, a Requested PLMN list is sent to the network; the network sends an Allowed PLMN list and a Rejected PLMN list to the UE; when the network abnormality occurs in the UE, the corresponding PLMN can be quickly and accurately selected to re-camp on the LTE network, so as to avoid wasting time for retrying each PLMN, that is, avoid invalid attempts of PLMNs in the Rejected PLMN list.

Example two:

the second example increases the judgment of whether the terminal is currently in a moving state, namely the moving speed and the position. When the terminal is in a state of a certain moving speed and tends to leave the current TA (i.e. does not stay (i.e. moves out) of the current TA range for the first duration), and at the same time, the UE receives an Attach Request or the network does not respond after the UE has sent the TAU Request 5 times, the scheme in the second example may be used to stay in the LTE network. If the TA to which the abnormal cell belongs is directly added into a forbidden list (FTA) under all conditions and the cells searched by the UE are in the FTA, the UE may camp on 2G or 3G at this time, which makes the user experience poor. This example scheme optimizes this: and when the UE tends to leave the current TA, adding the TA to which the abnormal cell currently appears into the forbidden list, and enabling the TA to continuously reside in the LTE network. Specifically, the present exemplary embodiment may include:

operation 1, when the UE receives an Attach Request or the network does not respond after the UE sends a TAU Request 5 times, the UE may determine whether the UE is continuously located in the TA range or is about to leave the TA range (corresponding to whether the electronic device is continuously located in the TA range of the current tracking area for the first duration) according to a self-contained gravity sensing system or other devices and big data calculation based on parameters (corresponding to the first reference information) such as a distance maintained between the UE and a base station when the network is normal and positioning.

Operation 2. if the UE will continue to be in the TA range for a short time (corresponding to the first time), the UE may use the existing scheme (or the scheme in the example above) to select which network to camp on. Otherwise, operation 3 is performed.

And operation 3. if the UE is about to leave the TA range, in order to save the network searching time to a certain extent, the TA can be added into the forbidden list, and cells suitable for residing are searched in other TAs so as to achieve the purpose of continuing to reside in the LTE network.

Therefore, the scheme of the second example can realize that the UE can quickly continue to camp on the LTE network in the mobile environment. In the second example, whether the UE is about to leave the TA may be determined by determining parameters such as the current moving speed and the current position of the UE; and when the UE is judged to be about to leave the TA, the LTE network can be continuously resided faster than the example, and the time-consuming phenomenon that the LTE network is continuously searched by other PLMNs in the abnormal TA is avoided.

Example three:

example three is a scheme combining example one and example two: when it is determined that the current UE moving speed does not move out of the current (located) TA within a short time (corresponding to the first time duration), continuing to camp on the LTE network as specified by example one; if the UE can move out of the TA to which the current abnormal cell belongs within a short time, the UE can continue to camp on the LTE network as specified by example two. Specifically, the third example may include:

operation 1, when the UE receives an Attach Request or the network does not respond after the UE sends a TAU Request 5 times, the UE may determine whether the UE is continuously located in the TA range or is about to leave the TA range according to a self-contained gravity sensing system or other devices and big data calculation based on parameters (corresponding to the first parameter information) such as a distance maintained between the UE and a base station when the network is normal, positioning, and the like.

Operation 2. if the UE will continue to be in the TA range for a short time, the UE may continue to select to camp on the LTE network using the scheme of example one. Otherwise, operation 3 may be performed.

Therefore, the third embodiment of the present invention can consider both the mobile and non-mobile scenarios of the UE, and enable the UE to continue to camp on the LTE network and to camp on the LTE network quickly based on PLMN selection and TA forbidden operation in the mobile scenario, respectively.

Furthermore, the scheme can also count the areas where the user falls back to 2G or 3G and other available PLMNs are located due to 4G network abnormality in each area in a big data mode, and push an accurate scheme for continuing to reside in the LTE network to the user by combining the moving speed of the user when the user is abnormal.
