Description

Terminal search method and terminal

Technical field

The present invention relates to communication technologies, and in particular, to a network search method and terminal for a terminal.

Background technique

With the advancement of communication technology, various communication terminals have also rapidly developed. The development is particularly fast due to the convenience of the mobile terminal. In the prior art, in order to ensure that the mobile terminal can normally use various services, it is necessary to rely on the network provided by the operator, that is, the mobile terminal must be in a place with network coverage when in use. However, under the existing network, not all places are covered by the network, in some indoor closed areas, such as elevators, basements, etc., or outdoor network coverage blind spots, such as densely populated areas, remote mountain areas and other local network coverage. Both are poor. Once the mobile terminal is in a place where it is not covered by the network or lost, the mobile terminal needs to try a network search to reacquire the network.

In the prior art, the process of searching for a network after the terminal is dropped out of the network adopts a two-layer structure, that is, first performing a historical frequency search network, and then performing a full-band search network, wherein the historical frequency search network refers to searching for the storage of the mobile phone. The frequency information that has been parked, the full-band search network refers to searching all the frequency bands supported by the mobile phone. Moreover, in the prior art, the frequency of performing the historical frequency search network is the same as the frequency of performing the full frequency search network. For example, after the terminal is dropped, the search is performed once at the historical frequency, and then the entire frequency band is searched again. Searching at historical frequencies and full-band searches is based on the same frequency. Understandably, the historical frequency search network is easier to find available networks and the time for performing historical frequency search is short, and the time for searching the entire frequency band is long.

However, when the terminal enters the network coverage environment from the no-network environment, the prior art network search solution often causes the terminal to not quickly find the available frequency points, and the search time is long, and the power consumption of the terminal is too large.

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The terminal involved in the embodiment of the present invention, that is, the user equipment, may be a wireless terminal or a wired terminal. The wireless terminal includes a device that provides voice and/or data services to the user. Alternatively, the device can be a handheld device with wireless connectivity, or other processing device connected to the wireless modem. Moreover, the wireless terminal can also communicate with one or more core networks via a radio access network (eg, RAN, Radio Access Network), for example, the wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" "Phone" and a computer having a mobile terminal, which may be a portable, pocket-sized, handheld, computer-integrated or in-vehicle mobile device that can interact with the core network for voice and/or data.

In the prior art, the frequency at which the terminal performs historical frequency search is the same as the frequency at which the full frequency search is performed, and the time for performing full frequency search is longer than the time for performing historical frequency search, and the function of performing full frequency search is performed. The power consumption of the historical frequency point search network is large. When the terminal enters the network coverage from the no-network environment In the environment, the terminal performs the search according to the prior art method. If the network is not searched when the historical frequency search is performed, the terminal performs a full frequency band with relatively long time and relatively large power consumption. Search the net. The method provided by the embodiment of the present invention is to solve the above technical problem of the prior art.

The technical solutions of the present invention will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

FIG. 1 is a schematic flowchart diagram of a method for searching a network of a terminal according to an embodiment of the present invention. The executor of the method may be a terminal, and the terminal is pre-set with a timer set, where the timer set includes a first timer and a second timer, and the duration of the first timer is smaller than that of the second timer. duration. As shown in Figure 1, the method includes:

S101: Determine a type of the terminal timeout timer, where the type of the timeout timer includes a first timer or a second timer.

Specifically, in a network with good network coverage, the terminal generally searches for the network through a certain frequency point, and determines that the network threshold of the network is a threshold that the terminal can reside, and the terminal resides on the network. And perform signaling or data interaction with certain network elements in the network. When the terminal is in the no-network coverage area, the terminal is in the offline state. If the terminal moves from the no-network coverage area to the network coverage area, the terminal starts the network search process within a preset time. In this embodiment, when the terminal moves from the no-network coverage area to the network coverage area, the terminal starts the preset timer of the terminal within a preset time, and determines the timeout timer when the started timer expires. Type is the first timer or the second timer. Optionally, since the timer is preset in the terminal by using the software, the terminal can learn whether the current timeout timer type is the first timer or the second timer by executing the corresponding software thread. It should be noted that the manner in which the terminal determines the type of the timeout timer is not limited in the embodiment of the present invention.

S102: Determine a network search mode of the terminal according to the type and association relationship of the timeout timer, where the association relationship is a mapping relationship between a network search mode of the terminal and a timer in the timer set. And the searching mode of the terminal corresponding to the first timer in the association relationship is a historical frequency search network, and the searching mode of the terminal corresponding to the second timer is a full-band search network.

S103: Trigger the terminal to perform network search according to the determined search mode.

Specifically, the terminal may determine whether to perform historical frequency search or full frequency search according to the type of the current timeout timer and the foregoing association relationship. In addition, the duration of the first timer may be set according to the duration of the historical frequency search network, and the duration of the second timer may be set according to the duration of the full-band search network. Optionally, the duration of the first timer is equal to the historical frequency. The length of the second timer from the start to the end of the search network is equal to the length of the full-band search network from the beginning to the end. The terminal performs different network searching methods according to timers of different durations (historical frequency search or full-band search network), that is, the duration of the first timer corresponding to the historical frequency search network is smaller than that of the full-band search network. The duration of the second timer, and the time of the historical frequency search network is short; therefore, according to the solution provided by the embodiment of the present invention, the number of times the terminal performs the historical frequency search network is greater than the execution of the full frequency search network in a period of time. frequency. Moreover, since the number of times the terminal performs the full-band search network is reduced correspondingly, the power consumption of the terminal is reduced and the speed of network recovery is accelerated.

It should be noted that the historical frequency point involved in this embodiment refers to the frequency point that the terminal once camped on the network through the frequency point. The full frequency band involved in this embodiment refers to all frequency bands supported by the terminal, such as terminal support. In the GSM system, the WCDMA system and the LTE system, the entire frequency band includes the Global System for Mobile Communication (GSM) standard, the Wideband Code Division Multiple Access (WCDMA) system and the long-term. The frequency band information corresponding to the evolution (Long Term Evolution, hereinafter referred to as LTE).

Optionally, the terminal may acquire an association between the network search mode of the terminal and the timer in the timer set in the process of moving from the network coverage area to the network coverage area, or may be the user in the internal memory of the terminal. The association relationship is preset, and when the terminal needs to use the association relationship, the association relationship is invoked from the memory by using corresponding software. In the association relationship, the network search mode of the terminal corresponding to the first timer is a historical frequency search network, that is, the terminal searches for the network only on the historical frequency information when the terminal searches for the network; and the network search mode of the terminal corresponding to the second timer For the full-band search network, the terminal searches for the frequency information in the full frequency range.

In order to better understand the technical solution of the embodiment of the present invention, a simple example is used herein for explanation:

Suppose the terminal sets the duration of the first timer to 2s, the time for the terminal to perform historical frequency search is 2s, the duration of the second timer is 10s, and the time for the terminal to perform full-band search is 10s. During the process of moving the environment to the network coverage environment, the terminal starts the first timer and the second timing (Assuming two timers are started at 0s, the two timers start counting from 0s). When the time reaches 2s, it is determined that the first timer expires, and the terminal performs historical frequency search. When the 4s is used, the historical frequency of the terminal ends the network search, and it is assumed that the terminal has not successfully searched the network at the historical frequency. For the first timer, the time reaches the 4th from the 2nd s, so the first timer starts again at the 4th s, and when the time reaches the 6th, it is determined that the first timer expires (the second timer expires 6s) If the timeout has not expired, the terminal continues to search the network at the historical frequency. When the 8th s, the historical frequency of the terminal ends the search, and it is assumed that the terminal has not succeeded in searching the network at the historical frequency; for the first timer For example, the time reaches the 8th s from the 6th s, so the first timer starts again at the 8th s. When the time reaches the 10th s, it is determined that the first timer expires (the second timer also times out, but the terminal is now You can choose to search the historical frequency point first. Then the terminal continues to search the network at the historical frequency. If the search is successful, the terminal will stay on the network through the historical frequency, no need to conduct full-band search. If the secondary search network is unsuccessful, the terminal will proceed again at the 12th s. Band network search. According to the example, the duration of the first timer is different from the duration of the second timer, and the duration of the first timer is less than the duration of the second timer, so that the terminal performs the historical frequency search every 2 seconds. The full-band search network is performed every 10s, so that the search frequency of the terminal performing the historical frequency search network is higher than the search frequency of the full-band search network, because the historical frequency search time is short and it is easier to search the network, so The embodiment of the invention makes the historical frequency point search network with higher frequency, and the full frequency search network performs lower frequency search network, thereby making the terminal easier to search the network, and the frequency of performing full frequency band search is low, and the terminal is lowered. Power consumption and speed up network recovery.

In the prior art, once the terminal is dropped, it will start the historical frequency search network. When the terminal moves from the no network coverage area to the network coverage area, it is still in the process of the historical frequency point search. If there is no network coverage area (or signal blind area), the mobile phone will automatically jump to the full-band search network after searching for the network at the historical frequency. When the mobile phone moves to the network coverage area (or the signal normal area), the current operation is performed. It is the full-band search network. At this time, it is possible to skip the historical frequency or the available frequency. That is, the frequency of the terminal performing the historical frequency search in the prior art is the same as the frequency of performing the full-band search network, resulting in the terminal being unable to The effective search for the available frequency points, and the search time is long, and the power consumption of the terminal is too large; however, the embodiment of the present invention adopts a layered network searching mechanism, and the terminal determines which type the terminal according to according to the type of the timeout timer. The search mode is used to search the network (that is, according to the type of the timeout timer, which kind of network search process is performed by the terminal), and the frequency of the terminal performing the historical frequency search is higher than that by setting the timer with different durations. Whole frequency band search network, so that the terminal can quickly be searched The frequency point is used; and, since the frequency at which the terminal performs the full-band search network is low, the power consumption of the terminal is reduced and the speed of network recovery is accelerated.

According to the method for searching the terminal of the present invention, the terminal triggers the terminal according to the type and associated relationship of the determined timeout timer according to the timer of the preset duration, and when the timer started by the terminal times out. Search the network to search the net. The method provided by the embodiment of the present invention adopts a layered network searching mechanism, and the terminal determines, according to the type of the timeout timer, which network search mode is used for searching, and sets the timer to perform historical frequency search by setting a timer with different durations. The frequency of the network is higher than the frequency of performing the full-band search network, so that the terminal can quickly search for the available frequency points; and, because the frequency of the terminal performing the full-band search network is low, the power consumption of the terminal is reduced and the network recovery is accelerated. speed.

In order to solve the problem that multiple timers are timed out at the same time, on the basis of the embodiment shown in FIG. 1 , as a possible implementation manner of the embodiment of the present invention, the specific process of establishing a relationship between the terminals involved in the embodiment is provided. That is, before the foregoing S101, the method further includes: establishing the association relationship according to the priority information between the historical frequency point and the full frequency band preset by the terminal; wherein the priority information includes: the historical frequency The priority of the point is higher than the priority of the full frequency band. Therefore, when multiple timers are timed out, the preferred network search mode may be determined according to the priority information in the association relationship.

Specifically, when establishing the association relationship, the terminal may establish the association relationship according to the priority information of the frequency point information supported by the terminal. Specifically, the terminal may set the frequency point information with high priority to the frequency point information with high search frequency, and set the frequency point information with lower priority to the frequency point information with low search frequency. In this embodiment, since the duration of the first timer is less than the duration of the second timer, the frequency of the historical frequency search network is higher than the frequency of the full frequency search network, and the priority of the historical frequency point is higher than the full frequency band. The priority is further increased the frequency of the historical frequency search network, reducing the frequency of the full-band search network, which is conducive to reducing power consumption.

On the basis of the embodiment shown in FIG. 1 , as another possible implementation manner of the embodiment of the present invention, another specific process of establishing a relationship between terminals in this embodiment is provided. Further, the foregoing timer set may further include a third timer, where the duration of the third timer is greater than the duration of the first timer and less than the duration of the second timer; the priority information further includes: the terminal The priority of the supported first frequency band is lower than the priority of the historical frequency point, and the priority of the first frequency band is higher than the priority of the full frequency band, and the first frequency band is a registered public land mobile network ( Registered Public Land Mobile Network (hereinafter referred to as RPLMN) Carrier-supported frequency band information. Before the foregoing S101, the method may further include: establishing the association relationship according to the historical frequency point preset by the terminal, the priority information between the first frequency band and the full frequency band; The searching mode of the terminal corresponding to the third timer in the association relationship is the first frequency band search network.

Specifically, the terminal may add a third timer to the timer set, and set the duration of the third timer to the duration of the first frequency band search. The first frequency band may be preset by the terminal in the memory or obtained by an over-the-air (OTA) update by the cloud server. In this embodiment, the setting of the first frequency band enables the terminal to search for the first frequency band in the scenario that the second timer does not time out, and the terminal cannot always find the available frequency point at the historical frequency point, thereby making the terminal You can quickly search for available frequency points.

The method provided by the embodiment of the present invention, by setting the duration of the third timer to the frequency at which the terminal performs the first frequency band search, so that the terminal does not time out in the second timer, and the terminal cannot always find the available time at the historical frequency point. In the frequency scenario, the first frequency band search network can be performed, so that the terminal can quickly search for the available frequency points, thereby improving the efficiency of the terminal search network.

2 is a schematic flowchart of another method for searching a network of a terminal according to an embodiment of the present invention. On the basis of the foregoing embodiment, the embodiment relates to a specific process for the terminal to perform network search when the started timer expires when the timer set includes the first timer, the second timer, and the third timer. Of course, when the timer set includes only the first timer and the second timer, the execution process of the following embodiments may also be referred to, and the specific execution process is similar. Further, the above S102 specifically includes:

S201: Determine whether the timer in the timer set times out.

Specifically, when the terminal is in a network-free coverage area, the terminal is in a dropped state. If the terminal moves from the no-network coverage area to the network coverage area, the terminal starts a timer within a preset time and determines whether the timer expires. Therefore, it is determined that the type of the timeout timer is the first timer or the second timer or the third timer. Optionally, the terminal can start the first timer, the second timer, and the third timer at the same time, and monitor whether the three timers expire.

S202: When any timer expires, the terminal is triggered to perform network search according to the network search mode corresponding to the timeout timer.

Specifically, when the terminal determines that the first timer of the three timers expires, the terminal performs a historical frequency point search network corresponding to the first timer according to the association relationship; when the terminal determines that the second timer is over At time, the terminal performs a first frequency corresponding to the third timer according to the association relationship The segment search network; when the terminal determines that the second timer expires, the terminal performs a full-band search network corresponding to the second timer according to the association relationship. It should be noted that, when the terminal performs network search according to the network search mode corresponding to any timer in the timer set, when other timers in the timer set have timed out, the terminal will mount other timers. The operation is performed (ie, the network search process corresponding to the other timers is not triggered), and the terminal performs the other timing according to the association relationship and the priority information preset by the terminal, when the terminal performs the current search process end time. Corresponding search network process.

It should be noted that other timers mentioned herein may be one timer or two timers. If the terminal searches for the network according to the network search mode corresponding to any timer in the timer set, the other two timers in the timer set are timed out, and when the terminal performs the current network search process, the terminal may The network is searched according to the association relationship and the priority of the frequency information in the network search mode corresponding to the two timers.

In order to better understand the technical solution of the embodiment of the present invention, a simple example is illustrated here. The example is specifically described in conjunction with the time axis and the search network corresponding relationship diagram shown in FIG. 3:

Assume that the duration of the first timer (T1) is 2s, the time for the terminal to perform historical frequency search is 2s, the duration of the third timer (T3) is 10s, and the time for the terminal to perform the first frequency search is 10s. The duration of the second timer (T2) is 1 min, and the time for the terminal to perform full-band search is 1 min.

When the terminal moves from the no-network environment to the network coverage environment, the terminal starts the first timer, the second timer, and the third timer (assuming that all three timers are started at 0s, the three timers start from 0s) Timing). When the time reaches 2s, it is determined that the first timer expires, and the terminal performs historical frequency search. When the 4s is used, the historical frequency of the terminal ends the network search, and it is assumed that the terminal has not successfully searched the network at the historical frequency. For the first timer, the time reaches the 4th from the 2nd s, so the first timer starts again at the 4th s, and the first timer expires when the time reaches the 6th s (the second timer and the third When the timer expires in the 6th s, the terminal continues to search the network at the historical frequency. When the 8s is used, the historical frequency of the terminal ends. Therefore, it is assumed that the terminal has not succeeded in searching the network at the historical frequency. For the first timer, the time reaches the 8th s from the 6th s, so the first timer starts again at the 8th s. When the time reaches the 10th s, it is determined that the first timer expires (the third timer is at the time) At 10s, it is also determined to be a timeout, but the terminal determines that the historical frequency point search is performed according to the historical frequency point and the priority of the first frequency band, and the third timer is mounted and operated, and the terminal continues to search at the historical frequency point. Net, when the 12th, the terminal's historical frequency point search network ends (in 12s, that in history At the end of the frequency search network, the first timer starts again; if the terminal is still unsuccessful in searching the network at the historical frequency point, the terminal is between 12s and 22s because the previous third timer has timed out. The first frequency band is searched. The first timer expires at the 14th s. However, because the current terminal performs the first frequency band search, the terminal mounts the first timer until the first frequency band is searched. Triggering the terminal to perform the historical frequency search network; if it is assumed that the terminal is still unsuccessful in searching the network in the first frequency band, the third timer is started again in the 22ss, and the terminal performs the historical frequency from the 22s to the 24s. Point search network; if it is assumed that the search network is still unsuccessful at the historical frequency, the terminal starts the first timer again at the 24th, and when the time reaches 26s, it determines that the first timer expires, then the terminal is in the 26s to the first The historical frequency search network is executed within 28s; if it is assumed that the search network is still unsuccessful at the historical frequency, the terminal starts the first timer again at the 28th, and when the time reaches 30s, it determines that the first timer expires. Terminal in the 30s to 32s time If the search network is still unsuccessful at the historical frequency, the first timer starts again at the 32s, and since the third timer is started in the 22s, it is in the 32s. It is determined that the third timer has timed out, so the terminal performs the first frequency band search in the 32s to 42s time (the first timer has timed out in the 34ss, because the terminal is currently performing the first frequency band search, the terminal At this time, the first timer is mounted and operated until the first frequency band is searched for the network; if it is assumed that the network search in the first frequency band is still unsuccessful, the terminal performs historical frequency search in the 42s to 44s time, and At the 42th s, the third timer is started again (ie, the third timer is started again at the end of the first frequency search); if it is assumed that the search is still unsuccessful at the historical frequency, the terminal starts the first again at the 44s. The timer, when the time reaches 46s, determines that the first timer expires, the terminal performs historical frequency search in the 46s to 48s time; if it is assumed that the search is still unsuccessful at the historical frequency, then in the 48s When the first timer starts again, when When the first timer expires, it is determined that the first timer expires, and the terminal performs historical frequency search in the 50s to 52s time; if it is assumed that the search is still unsuccessful at the historical frequency, the terminal starts again in the 52s. a timer, and since the aforementioned third timer is started in the 42s, the third timer has timed out at the 52ss, so the terminal performs the first frequency band search (the first timer) in the 52s to 62s time. At the 54s, the timeout has expired. Since the terminal is currently searching for the first frequency band, the terminal mounts the first timer at this time until the first frequency band is searched, and the second timer is determined at the 60s. Timeout, because the terminal is currently searching for the first frequency band, the terminal also mounts the second timer at this time until the first frequency band is searched. If it is assumed that the first frequency band search network is still unsuccessful, then at the 62s, the terminal according to the historical frequency point and the priority information of the full frequency band Make sure to search the historical frequency point first, then perform the full-band search network, and so on, until the terminal search network is successful.

The frequency is higher than the frequency at which the first frequency band is searched, and the frequency at which the terminal performs the first frequency band search is higher than the frequency at which the full frequency band search is performed. Since the historical frequency search time is short and the network is easier to search, the embodiment of the present invention makes the historical frequency point search for a higher frequency, and the first frequency search network performs the lower frequency search network, and the full frequency search network performs the search.

Optionally, when multiple timeout devices time out at the same time, the order of the network search mode may be determined according to the priority of different network search modes. For example, the priority of the historical frequency point is set to be greater than the first frequency band, and the priority of the first frequency band is greater than the full frequency band. When the first timer and the second timer simultaneously time out, the manner of searching for the historical frequency point is preferentially selected.
