Description

A communication method, device, storage medium and chip system

technical field

The present application relates to the field of communication, and in particular, to a communication method, device, storage medium and chip system.

Background technique

The signal of the underground garage is very weak. After the user enters the underground garage, it may not be able to successfully camp on the wireless communication network, for example, it may not be able to camp on the Long Term Evolution (LTE) network. In order to save power consumption and prevent the mobile phone from repeatedly retrying on the network that cannot be accessed, one of the current solutions is to start the T3402 timer when the number of attachment failures reaches the preset value, and the current tracking area (Tracking Area, TA ), such as the TA of an LTE network, is added to the list of forbidden TAs (Forbidden Tracking Areas for Roaming). In this way, the mobile phone will not attempt to access the current TA until the T3402 timer reaches the specified duration, that is, the terminal device will not attempt to camp on the LTE network until the T3402 timer reaches the specified duration.

The non-access stratum (Non-Access Stratum, NAS) prohibits the TA for a period of time gradually, for example, 5 minutes > 10 minutes > 12 hours. That is, when the number of times that the mobile phone resides on the current TA reaches the preset number of times, the T3402 timer is set to 5 minutes for the first time. When 5 minutes arrive, the mobile phone will try to camp on the LTE network again. If it still cannot camp on the current TA, the current TA will be added to the forbidden TA list again, and the T3402 timer will be set to 10 minutes. When 10 minutes arrive, the mobile phone will try to camp on the LTE network again. If it still cannot camp on the current TA, the current TA will be added to the forbidden TA list again, and the T3402 timer will be set to 12 hours.

When the user leaves the underground garage, if the TA is still banned, the mobile phone will not try to access the LTE network. From the above example, it can be seen that the set duration of the T3402 timer is relatively long, so that the mobile phone cannot stay on the LTE network for a long time.

SUMMARY OF THE INVENTION

The present application provides a communication method, a device, a storage medium and a chip system, and a storage medium and a chip system, which are used to improve the network residency problem of a wireless communication device in a weak signal area.

In a first aspect, the present application provides a method for a wireless communication device, in which the cellular network access range of the wireless communication device is restricted for a first time period. Before the first time period expires, enable the autonomous identification strategy of the weak signal area scene to identify whether the wireless communication device conforms to the scene of leaving the weak signal area, and cancel the cellular network connection after identifying that the wireless communication device conforms to the scene of leaving the weak signal area Access range restrictions in order to access previously restricted cellular networks before the first time period expires. The restrictions on the access range of the cellular network include one or more of the following restrictions: the networks of all radio access technologies are disabled, the networks of the first radio access technology are disabled, the first tracking area is disabled, and the first cell is disabled. Disabled.

It can be seen that before the first time period expires, if you leave the weak signal area, the restriction on the access range of the cellular network can be immediately canceled. In this way, the restricted time period of the cellular network can be shortened and the problem of network camping in the weak signal area can be improved.

In this application, weak signal areas may include areas with weak (or no) signals of one or more specified wireless access technologies, such as areas such as underground garages, tunnels, and remote mountainous areas.

In this application, the weak signal area is used as the underground garage, but those skilled in the art know that the application scope of the solution is not limited to this. When the weak signal area is used as the underground garage, the corresponding: "autonomous identification strategy of weak signal area scene" can be replaced with "autonomous identification strategy of underground garage scene", and "scenario of weak signal area" can be replaced with " Underground Garage Scene". Based on this, the present application provides a method for a wireless communication device, in the method:

The wireless communication device limits the cellular network access range of the wireless communication device for the first time period. The restrictions on the access range of the cellular network include one or more of the following restrictions: the networks of all radio access technologies are disabled, the networks of the first radio access technology are disabled, the first tracking area is disabled, and the first cell is disabled. Disabled. Before the first time period expires, the autonomous identification strategy of the underground garage scene is enabled to identify whether the wireless communication device is suitable for the scene of leaving the underground garage. After recognizing that the wireless communication device fits the scenario of leaving the underground garage, the restriction on the access range of the cellular network is removed so as to access the previously restricted cellular network before the first time period expires. In this way, the restricted time of the cellular network can be shortened, and the problem of network residency in the underground garage scene can be improved.

It should be understood that, in the solutions provided by the embodiments of the present application, the wireless communication device may be a wireless communication device, or may be a part of a device in the wireless communication device, such as an integrated circuit product such as a system chip or a communication chip. The wireless communication device may be a computer device that supports wireless communication functionality.

Specifically, the wireless communication device may be a terminal such as a smart phone, or may be a wireless access network device such as a base station. A system-on-chip may also be referred to as a system on chip (system on chip, SoC), or simply referred to as a SoC chip. The communication chip may include a baseband processing chip and a radio frequency processing chip. Baseband processing chips are also sometimes referred to as modems or baseband chips. The radio frequency processing chip is also sometimes referred to as a radio frequency transceiver (transceiver) or radio frequency chip. In physical implementation, some or all of the communication chips may be integrated inside the SoC chip. For example, the baseband processing chip is integrated in the SoC chip, and the radio frequency processing chip is not integrated with the SoC chip.

In a possible implementation, in order to improve the flexibility of the solution, whether the wireless communication device is eligible for the scenario of leaving the underground garage can be autonomously identified based on one or more of the following:

Based on data from gyroscopes and gravity sensors;

According to the strength of the satellite positioning signal;

According to the signal strength or signal quality of the cellular network;

According to the neighbor cell information of the cellular network;

According to a preset cellular network map; wherein the preset cellular network map includes: one or more geographic areas, and cellular network information corresponding to the geographic areas;

Identify whether the wireless communication device is suitable for entering the underground garage.

In a possible implementation manner, according to the data of the gyroscope and the gravity sensor, it is determined whether the movement mode of the wireless communication device satisfies the following rule: the movement direction of the wireless communication device is converted from the oblique upward direction to the horizontal direction, and the movement direction of the wireless communication device is in the horizontal direction. Continued exercise for longer than the preset duration. If this rule is satisfied, the wireless communication device is more likely to conform to the scene of leaving the underground garage.

In a possible implementation manner, it is determined whether the satellite positioning signal of the wireless communication device satisfies one or more of the following rules: the satellite positioning signal of the wireless communication device starts from scratch, and the duration of the signal exceeds a preset time duration; the satellite positioning signal of the wireless communication device changes from weak to strong, and the duration of the strong signal exceeds the preset duration. If this rule is satisfied, the wireless communication device is more likely to conform to the scene of leaving the underground garage.

In a possible implementation, the preset cellular network map may be updated according to the result of the autonomous identification strategy of the underground garage scene. In this way, the autonomous identification of the underground garage scene can be performed based on the cellular map with more accurate information.

In a possible implementation, when the cellular network access range of the wireless communication device is restricted within the first time period, the autonomous identification strategy of the underground garage scene is enabled by default. In this way, corresponding processing can be performed on each cellular network restriction more comprehensively, so that the speed of the wireless communication device returning to the wireless access technology network can be accelerated as much as possible in each cellular network restriction.

In a possible implementation, the autonomous identification strategy of the underground garage scene is further used to identify whether the wireless communication device conforms to the scene of entering the underground garage. In a possible implementation, when it is recognized that the wireless communication device has entered the underground garage, the autonomous identification strategy of the underground garage scene can be activated. In this way, when it is recognized that the wireless communication device has left the underground garage, the cellular network access can be cancelled in time. In this way, the number of starts of the autonomous identification strategy for starting the underground garage scene can be reduced, which is more in line with the actual application scene.

Taking the network of the first radio access technology as a 4G network and the network of the second radio access technology as a 2G or 3G network as an example, a possible scenario is introduced:

The wireless communication device attempts to reside on the 4G network, and when the number of times of attachment failure reaches a preset value, the corresponding current TA is added to the forbidden list (Forbidden Tracking Areas for Roaming). If the current 2G or 3G signal can be found, it can reside in the 2G or 3G network.

Among them, TA is an area used for paging and location update. Multiple cells can be configured with the same TA, and one cell belongs to one TA. When the wireless communication device is in an idle state, the Core Network (CN) can know the The TA where the wireless communication device is located, and when the wireless communication device in the idle state needs to be paged, the core network performs paging in all cells in the TA where the wireless communication device is registered.

The length of time that NAS prohibits TA is progressive, such as 5 minutes > 10 minutes > 12 hours. For example, when the number of attachment failures reaches the preset value, the current TA is added to the TA prohibition list, and the duration of T3402 is set to 5 minutes. During these 5 minutes, the wireless communication device will not attempt to access the corresponding TA. community. During these 5 minutes, even if the wireless communication device searches for the cell corresponding to the TA, because the TA is in the forbidden list, the wireless communication device will not attempt to access the cell corresponding to the TA.

On the other hand, when 5 minutes arrive, the TA will be removed from the TA prohibition list, it can also be said that the TA prohibition is stopped, or the TA is stopped, or the TA's prohibition time is reached, in this case Next, the wireless communication device will search for the cell corresponding to the TA, and may attempt to access when the cell corresponding to the TA is found. However, if the attachment still fails and the attachment failure reaches the preset value, the duration of T3402 will be set to 10 minutes this time. Similarly, within these 10 minutes, the wireless communication device will not attempt to access the cell corresponding to the TA. When 10 minutes arrive, if the wireless communication device still fails to attach and the attachment failure reaches the preset value, the duration of T3402 will be set to 12 hours this time.

The embodiments of the present application provide a solution for using an autonomous identification strategy in a weak signal area (such as an autonomous identification strategy in an underground garage scene), when it is recognized that the wireless communication device leaves the weak signal area (such as an underground garage), stop in advance Forbid the TA to try to camp on the LTE network. In this way, the speed of the wireless communication device camping on the LTE network can be accelerated, and the duration of the wireless communication device camping on the low-standard network can also be reduced, and the function of the wireless communication device will not be significantly affected. consumption.

It should be noted that the embodiment of this application involves the concept of "first duration". Combined with the above examples, the duration of the NAS prohibition of TA is progressive, 5 minutes for the first time, 10 minutes for the second time, and 12 hours for the third time , the "first duration" in this embodiment of the application may refer to 5 minutes when the TA is added to the TA prohibition list for the first time, or 10 minutes when the TA is added to the TA prohibition list for the second time, or 12 hours to add a TA to the TA banned list for the third time. That is to say, the "first duration" in the embodiment of the present application refers to the restriction duration specified when the event "restricting the cellular network access range of the wireless communication device" occurs at any time, and this restriction duration may be a gradual change The first value in the duration of , and possibly later values in the duration of the gradual change. It should be noted that the "first time period" does not only refer to the "first time" when the event of "restricting the cellular network access range of the wireless communication device" occurs. 5 minutes when TA is added to the TA banned list, it can also be 10 minutes or 12 hours mentioned later, etc.

Based on the above content, FIG. 2 exemplarily shows a schematic flowchart of a method for a wireless communication device provided by an embodiment of the present application. The wireless communication apparatus in this embodiment of the present application may be a chip or a terminal device (for example, it may be the terminal device 100 in FIG. 1 above). The chip may be a baseband chip or a network chip, and may also include a group of chips of a baseband chip and a radio frequency chip. As shown in Figure 2, the method includes:

Step 211: Restrict the cellular network access range of the wireless communication device within a first time period; wherein, the restriction on the cellular network access range includes one or more of the following restrictions: all wireless access technology networks are disabled, the first The network of the radio access technology is disabled, the first tracking area is disabled, and the first cell is disabled.

Step 212, before the first time period expires, enable the autonomous identification strategy of the weak signal area scene to identify whether the wireless communication device conforms to the scene of leaving the weak signal area;

Step 213, after recognizing that the wireless communication device meets the scenario of leaving the weak signal area, cancel the restriction on the access range of the cellular network, so as to access the previously restricted cellular network before the first time period expires.

In this embodiment of the present application, the weak signal area may include areas with weak (or no) signals of one or more specified wireless access technologies, such as areas such as underground garages, tunnels, and remote mountainous areas. In the embodiments of the present application, the weak signal area is used as the underground garage, but those skilled in the art know that the application scope of the solution is not limited to this. When the weak signal area is used as the underground garage, the corresponding: "autonomous identification strategy of weak signal area scene" can be replaced with "autonomous identification strategy of underground garage scene", and "scenario of weak signal area" can be replaced with " Underground Garage Scene". Based on this, the solution provided in FIG. 2 can be replaced with the solution provided in FIG. 3 . As shown in FIG. 3 , the method includes:

Step 201: Restrict the cellular network access range of the wireless communication device within a first time period; wherein, the restriction on the cellular network access range includes one or more of the following restrictions: the networks of all wireless access technologies are disabled, the first The network of the radio access technology is disabled, the first tracking area is disabled, and the first cell is disabled.

Step 202, before the first time period expires, enable the autonomous identification strategy of the underground garage scene to identify whether the wireless communication device conforms to the scene of leaving the underground garage;

Step 203 , after recognizing that the wireless communication device conforms to the scenario of leaving the underground garage, cancel the restriction on the access range of the cellular network, so as to access the previously restricted cellular network before the first time period expires.

It can be seen that before the first time period expires, if you leave the underground garage, the restriction on the access range of the cellular network can be immediately canceled. In this way, the restricted time period of the cellular network can be shortened and the problem of network residency in the underground garage can be improved.

In step 201, in a possible implementation manner, a first trigger condition may be set, and when the first trigger condition is satisfied, the cellular network access range of the wireless communication device is restricted for a first time period. Wherein, the first trigger condition may have various specific implementation forms. Several possible examples of the first trigger condition will be described below in conjunction with some specific scenarios. On the other hand, in the foregoing step 201, the cellular network access range includes the network search range of the cellular network, and may also include the network access range. Scenario A and Scenario B are introduced separately below.

Scenario A: The cellular network access range includes the cellular network search range.

In Scenario A, it can be divided into the following four scenarios: Scenario A1, Scenario A2, Scenario A3 and Scenario A4 according to the limitation of the access range of the cellular network.

Scenario A1: The cellular network access range includes the search range of the cellular network, and the restriction of the cellular network access range includes: all wireless access technology networks are disabled.

In the scenario A1, the first trigger condition may include one or more of the following condition A1-1, condition A1-2, and condition A1-3. For example, the condition A1-1 may be included. Another example may include condition A1-2.

Condition A1-1: The number of attachment failures within a preset time period reaches a preset number of failures.

Condition A1-1 may specifically include one of the following:

The number of failures to attach to the network of at least one radio access technology within a preset time period reaches a preset number of failures;

The number of failures to attach to a network of a specified radio access technology within a preset time period reaches the preset number of failures;

The number of failures of attaching to the networks of the specified multiple radio access technologies within the preset time period reaches the preset number of failures.

Condition A1-2: The signal of the wireless access technology network cannot be searched for within a preset time period.

Condition A1-2 may specifically include one of the following:

The signal of any wireless access technology network cannot be searched within the preset time period;

A signal of a network of a specified radio access technology (such as a network of the first radio access technology) cannot be searched for within a preset time period;

The signals of multiple networks specifying the radio access technology (for example, the network of the first radio access technology and the network of the second radio access technology) cannot be searched for within a preset time period.

Condition A1-3: It is recognized that the wireless communication device entered the underground garage.

In the condition A1-3, when it is recognized that the wireless communication device enters the underground garage, the signal of the underground garage is usually weak. Therefore, if the access range of the cellular network is triggered after the recognition of entering the underground garage, the power consumption can be saved .

In scenario A1, since the cellular network access range includes the search range of the cellular network, and the restriction of the cellular network access range includes: all wireless access technology networks are disabled, therefore, within the first time period, the wireless communication device The network search operation cannot be performed on the network of any wireless access technology, that is, the network search operation cannot be performed on all communication networks such as 5G, 4G, 2G or 3G within the first time period.

Correspondingly, in the scenario A1, after it is identified in the above step 203 that the wireless communication device conforms to the scenario of leaving the underground garage, the restriction on the access range of the cellular network is cancelled. That is, the network search operation of all radio access technology networks is allowed. Further, when a suitable cell is found, access is attempted.

In a possible implementation manner, when the scene of leaving the underground garage is identified in the above step 203, the cellular network access range restriction is cancelled. At this time, the wireless communication device will search for the wireless access with the highest standard priority that it can support. technology network, so that once the wireless communication device leaves the underground garage, it can reside on the network of the highest standard priority wireless access technology that it can support to provide services to users.

Scenario A2: The cellular network access range includes the search range of the cellular network, and the restriction of the cellular network access range includes: the network of the first radio access technology is disabled.

In the scenario A2, the first trigger condition may include one of the following conditions A2-1 and A2-2. Optionally, the first trigger condition may further include condition A2-3. Or the first trigger condition may only include condition A2-3.

Condition A2-1: The number of failures to attach to the network of the first radio access technology within a preset time period reaches a preset number of failures.

Condition A2-2: The network signal of the network of the first radio access technology cannot be searched for within a preset time period.

Condition A2-3: It is recognized that the wireless communication device entered the underground garage.

In scenario A2, since the access range of the cellular network includes the search range of the cellular network, and the restriction of the access range of the cellular network includes: the network of the first radio access technology is disabled, therefore, within the first time period, the wireless communication The device cannot perform a network search operation on the network of the first radio access technology. Whether the wireless communication device can perform a network search operation on networks of other wireless access technologies is not limited in this embodiment of the present application. In a possible implementation manner, in the scenario A2, within the first time period, the wireless communication device may perform a network search operation on networks of other wireless access technologies.

Generally speaking, the network penetration of a radio access technology with a higher standard priority is weaker, so the network of the first banned radio access technology may be the standard priority supported by the wireless communication device with a higher or highest priority. A wireless access technology network. In a possible implementation manner, after the network of the first radio access technology is disabled, the wireless communication device may reside on the network of the second radio access technology with a lower standard priority.

For example, if the network of the first radio access technology is a 4G network, and the network of the second radio access technology is a 2G or 3G network, the network search operation cannot be performed on the 4G network within the first time period. Possibly, the wireless communication device can search and reside on the 2G or 3G network. In this way, when the wireless communication device enters an area with weak 4G signal or no 4G signal, the wireless communication device can reside on the 2G or 3G network. , in order to provide services to users.

Correspondingly, in the scenario A2, after it is identified in the above step 203 that the wireless communication device conforms to the scenario of leaving the underground garage, the restriction on the access range of the cellular network is canceled, which may specifically refer to: canceling the disabling of the network of the first wireless access technology. , that is, a network search operation for the network of the first radio access technology is allowed. Further, when a cell of the network of the first radio access technology is searched, access is attempted. In this way, once the wireless communication device leaves the underground garage, the cell of the network of the first wireless access technology can be searched immediately, so that the speed of camping on the network of the first wireless access technology can be accelerated, and the time of camping on the wireless communication device can be shortened. The length of time to stay in the network of the radio access technology with the lower standard priority.

Scenario A3: The cellular network access range includes the search range of the cellular network, and the restriction of the cellular network access range includes: the first tracking area is disabled.

In the scenario A3, the first trigger condition may include one of the following conditions A3-1 and A3-2. Optionally, the first trigger condition may further include condition A3-3. Or the first trigger condition may only include condition A3-3.

Condition A3-1: The number of failures to attach to the first tracking area or the second tracking area within a preset time period reaches a preset number of failures, and the first tracking area is a neighboring tracking area of the second tracking area.

Condition A3-2: Before the access range of the cellular network is restricted, the cell is camped on in the first tracking area, and the network signal of the cell in the first tracking area cannot be searched for currently.

Condition A3-3: It is recognized that the wireless communication device entered the underground garage.

In scenario A3, since the access range of the cellular network includes the search range of the cellular network, and the restriction of the access range of the cellular network includes: the first tracking area is disabled, therefore, within the first time period, the wireless communication device cannot The first tracking area performs a network search operation, that is, the frequency points of the first tracking area cannot be searched.

For example, if the first tracking area is a tracking area under the network of the first wireless access technology, and the first wireless access technology is 4G, then the first tracking area can be added to the TA prohibition list, and the T3402 timer can be set, In this way, the network search operation cannot be performed on the first tracking area until the time of the T3402 timer arrives.

In Scenario A3, whether the wireless communication device can track other tracking areas except the first tracking area (other tracking areas except the first tracking area under the network of the first wireless access technology, The tracking area under the network of the other wireless access technology other than the network of the technology) performs the network search operation, which is not limited in this embodiment of the present application. In a possible implementation manner, in the scenario A3, within the first time period, the wireless communication device may search the network for other tracking areas except the first tracking area under the network of the first radio access technology. However, in practical applications, usually the coverage of one tracking area is relatively large, and currently within the coverage of the first tracking area, the success rate of searching other tracking areas of the first radio access technology may not be very large. Therefore, In a possible implementation manner, the network may not be searched for other tracking areas of the first radio access technology. Instead, search for networks of other radio access technologies other than the first radio access technology, such as networks of the second radio access technology, and try to reside in the network of the second radio technology.

For example, if the network of the first radio access technology is a 4G network, and the first tracking area is a tracking area under the 4G network, the network search operation cannot be performed on the first tracking area within the first time period. Possibly, the wireless communication device may perform a network search on other tracking areas other than the first tracking area (for example, other tracking areas other than the first tracking area of a 4G network, and tracking areas of a 2G or 3G network) And try to stay, it may stay on 2G or 3G network, so, when the wireless communication device enters the area with weak 4G signal or no 4G signal, the wireless communication device can stay on the 2G or 3G network in order to provide users with Serve.

Correspondingly, in scenario A3, after it is identified in step 203 that the wireless communication device conforms to the scenario of leaving the underground garage, the restriction on the access range of the cellular network is cancelled. Network search operation in the first tracking area. Further, when a cell in the first tracking area is found, access is attempted. In practical applications, usually the coverage of one tracking area is relatively large, and the underground garage may belong to the coverage of the first tracking area. In this way, once the wireless communication device leaves the underground garage, the cell in the first tracking area can be searched immediately. The speed of successful search can be increased, so that the speed of camping on the network of the first radio access technology can be accelerated, and the duration of the wireless communication device camping on the network of the radio access technology with a lower standard priority can be shortened.

Scenario A4: The cellular network access range includes the search range of the cellular network, and the restriction of the cellular network access range includes: the first cell is disabled.

In scenario A4, the first trigger condition may include one of the following conditions A4-1 and A4-2. Optionally, the first trigger condition may further include condition A4-3. Or the first trigger condition may only include condition A4-3.

Condition A4-1: The number of failures to attach to the first cell or the second cell within a preset time period reaches a preset number of failures, and the first cell is a neighbor of the second cell.

Condition A4-2: Before the access range of the cellular network is restricted, the nearest camping cell is the first cell, and the network signal of the first cell cannot be searched at present.

Condition A4-3: It is recognized that the wireless communication device entered the underground garage.

In scenario A4, since the access range of the cellular network includes the search range of the cellular network, and the restriction of the access range of the cellular network includes: the first cell is disabled, therefore, within the first time period, the wireless communication device cannot access the first cell. When a cell performs a network search operation, the frequency point of the first cell cannot be searched.

For example, if the first cell is a tracking area under the network of the first radio access technology, and the first radio access technology is 4G, the first cell can be added to the cell prohibition list, and a timer can be set. Before the timer expires, the network search operation cannot be performed on the first cell.

In scenario A4, whether the wireless communication device can perform a network search operation for other cells is not limited in this embodiment of the present application. In a possible implementation manner, in scenario A4, if the first cell is a cell under the first radio access technology, and the tracking area corresponding to the first cell is the first tracking area, then within the first duration, the wireless communication The device may respond to other cells other than the first cell (for example, it may be other cells other than the first cell in the first tracking area, or other cells other than the first tracking area in the network of the first radio access technology) Cells of the tracking area, and cells of networks of other radio access technologies other than the network of the first radio access technology) perform network search.

For example, if the network of the first radio access technology is a 4G network and the first cell is a cell of the first tracking area under the 4G network, the network search operation cannot be performed on the first cell within the first time period. Possibly, the wireless communication device may communicate to other cells other than the first cell (eg, other cells other than the first cell in the first tracking area of the 4G network, other cells other than the first tracking area of the 4G network) The cell in the tracking area, and the cell in the 2G or 3G network) search for the network and try to camp on, and may camp on the 2G or 3G network. In this way, when the wireless communication device enters the area with weak 4G signal or no 4G signal, the A wireless communication device may reside on a 2G or 3G network in order to provide services to users.

Correspondingly, in the scenario A4, after it is identified in the above step 203 that the wireless communication device conforms to the scenario of leaving the underground garage, the restriction on the access range of the cellular network is canceled, which may specifically refer to: canceling the prohibition of the first cell, that is, allowing the first cell to be disabled. A network search operation in a cell. Further, when the first cell is found in the search, access is attempted. In practical applications, if the wireless communication device enters the underground garage and leaves the underground garage, the wireless communication device may belong to the coverage of the first cell. In this way, once the wireless communication device leaves the underground garage, it can immediately The search in the first cell can improve the speed of successful search, thereby speeding up the speed of camping on the network of the first radio access technology, and shortening the time required for the wireless communication device to camp on the radio access technology with a lower standard priority. duration of the network.

Scenario B: The cellular network access range includes the connection range of the cellular network.

In Scenario B, it can be divided into the following four scenarios: Scenario B1, Scenario B2, Scenario B3 and Scenario B4 according to the limitation of the access range of the cellular network.

Scenario B1: The cellular network access range includes the connection range of the cellular network, and the restriction of the cellular network access range includes: all wireless access technology networks are disabled.

In scenario B1, the first trigger condition may include one of the aforementioned conditions A1-1 and A1-2. Optionally, the first trigger condition may further include condition A1-3. Or the first trigger condition may include only the conditions A1-3. For details, reference may be made to the relevant description in the foregoing scenario A1, which will not be repeated here.

In scenario B1, since the cellular network access range includes the connection range of the cellular network, and the limitation of the cellular network access range includes: all wireless access technology networks are disabled, therefore, within the first time period, the wireless communication device does not The connection operation (or the operation of attempting to access) can be performed on the network of any wireless access technology, that is, the connection operation cannot be performed on the network of all wireless access technologies such as 5G, 4G, 2G or 3G within the first time period. .

In scenario B1, whether the wireless communication device can search the network is not limited in this embodiment of the present application. For example, the wireless communication device may perform a network search operation on a network of any wireless access technology. For another example, in order to save power consumption, since the connection operation cannot be performed on the networks of any one wireless access technology, the network search operation may also not be performed on the networks of all wireless access technologies.

Correspondingly, in the scenario B1, after it is identified in the above step 203 that the wireless communication device conforms to the scenario of leaving the underground garage, the restriction on the access range of the cellular network is cancelled. That is, access operations to networks of all radio access technologies are allowed. That is, once it is recognized that the wireless communication device has left the underground garage, the searched suitable cell can be accessed.

In a possible implementation manner, when the scene of leaving the underground garage is identified in the above step 203, the cellular network access range restriction is cancelled. At this time, the wireless communication device will access the searched highest standard priority that it can support. In this way, once the wireless communication device leaves the underground garage, it can reside on the network of the highest priority wireless access technology that it can support to provide services for users.

Scenario B2: The cellular network access range includes the connection range of the cellular network, and the restrictions on the cellular network access range include: The network of the first radio access technology is disabled.

In scenario B2, the first trigger condition may include one of the aforementioned condition A2-1 and condition A2-2. Optionally, the first trigger condition may further include condition A2-3. Or the first trigger condition may only include condition A2-3. For details, refer to the relevant description in the foregoing scenario A2, which will not be repeated here.

In scenario B2, since the cellular network access range includes the connection range of the cellular network, and the limitation of the cellular network access range includes: the network of the first radio access technology is disabled, therefore, within the first time period, the wireless communication device A connection operation to the network of the first radio access technology is not possible.

In scenario B2, whether the wireless communication device can search the network is not limited in this embodiment of the present application. In a possible implementation manner, the wireless communication device may perform a network search operation on a network of any wireless access technology. In another possible implementation manner, in order to save power consumption, since the connection operation cannot be performed on the network of the first radio access technology, it is also possible to only connect other wireless connections except the network of the first radio access technology. Access the technical network to search the network.

Whether the wireless communication device can perform connection operations to networks of other wireless access technologies is not limited in this embodiment of the present application. In a possible implementation manner, in scenario B2, within the first time period, the wireless communication device may perform a connection operation on networks of other wireless access technologies.

For example, if the network of the first radio access technology is a 4G network, the connection operation to the 4G network cannot be performed within the first time period. Possibly, the wireless communication device can search the 2G or 3G network, and try to connect after searching for a suitable frequency point. In this way, when the wireless communication device enters an area with weak 4G signal or no 4G signal, the wireless communication device can A network residing on 2G or 3G provides services to users.

Correspondingly, in the scenario B2, after it is identified in the above step 203 that the wireless communication device conforms to the scenario of leaving the underground garage, the restriction on the access range of the cellular network is canceled, which may specifically refer to: canceling the disabling of the network of the first wireless access technology. , that is, an access operation to the network of the first radio access technology is allowed. In this way, once the wireless communication device leaves the underground garage, it can access the cell of the network of the first wireless access technology (it can be the cell of the network of the first wireless access technology searched in advance, or it can also be left underground. The cell of the network of the first wireless access technology that is searched after the garage), so that the speed of camping on the network of the first wireless access technology can be accelerated, and the time when the wireless communication device is camped on a lower standard priority can be shortened. The duration of the radio access technology network.

Scenario B3: The cellular network access range includes the connection range of the cellular network, and the restriction of the cellular network access range includes: the first tracking area is disabled.

In scenario B3, the first trigger condition may include one of the aforementioned conditions A3-1 and A3-2. Optionally, the first trigger condition may further include condition A3-3. Or the first trigger condition may only include condition A3-3. For details, refer to the relevant description in the foregoing scenario A3, which will not be repeated here.

In scenario B3, since the cellular network access range includes the connection range of the cellular network, and the limitation of the cellular network access range includes: the first tracking area is disabled, the wireless communication device cannot access the first tracking area for the first time period. A connection operation is performed in a tracking area, that is, an operation of attempting to access the first tracking area cannot be performed.

For example, if the first tracking area is a tracking area under the network of the first wireless access technology, and the first wireless access technology is 4G, then the first tracking area can be added to the TA prohibition list, and the T3402 timer can be set, so that , the first tracking area cannot be connected until the time of the T3402 timer expires.

In scenario B3, whether the wireless communication device can search the network is not limited in this embodiment of the present application. In a possible implementation manner, the wireless communication device may perform a network search operation on a network of any wireless access technology. In another possible implementation manner, in order to save power consumption, since the connection operation cannot be performed on the first tracking area, if the first tracking area is a tracking area in the network of the first radio access technology, the Other tracking areas than the first tracking area (eg, tracking areas of other first radio access technology than the first tracking area, and networks of other radio access technologies other than the first radio access technology) tracking area) to search the network. However, in practical applications, usually the coverage of one tracking area is relatively large, and currently within the coverage of the first tracking area, the success rate of searching other tracking areas of the first radio access technology may not be very large. Therefore, In a possible implementation manner, the network may not be searched for other tracking areas of the first radio access technology. Instead, search for networks of other radio access technologies other than the first radio access technology, such as networks of the second radio access technology, and try to reside in the network of the second radio technology.

In scenario B3, whether the wireless communication device can perform a connection operation on other tracking areas except the first tracking area is not limited in this embodiment of the present application. In a possible implementation manner, in scenario B3, within the first time period, the wireless communication device may connect to other tracking areas except the first tracking area under the network of the first radio access technology.

For example, if the network of the first radio access technology is a 4G network, and the first tracking area is a tracking area under the 4G network, the connection operation cannot be performed on the first tracking area within the first time period. Possibly, the wireless communication device may search for networks of all wireless communication technologies, and when searching for a suitable cell, if the cell does not belong to the first tracking area, it may attempt to access the cell.

Correspondingly, in scenario B3, after it is identified in step 203 that the wireless communication device conforms to the scenario of leaving the underground garage, the restriction on the access range of the cellular network is cancelled. Access operation of the first tracking area. In practical applications, usually the coverage of one tracking area is relatively large, and the underground garage may belong to the coverage of the first tracking area. In this way, once the wireless communication device leaves the underground garage, it can immediately access the cell in the first tracking area. operation (it may be the cell in the first tracking area that is searched in advance, or it may be the cell in the first tracking area that is searched after leaving the underground garage), so that the network camping on the first radio access technology can be accelerated. The speed can shorten the time that the wireless communication device resides on the network of the radio access technology with the lower standard priority.

Scenario B4: The cellular network access range includes the connection range of the cellular network, and the restriction of the cellular network access range includes: the first cell is disabled.

In scenario B4, the first trigger condition may include one of the aforementioned condition A4-1 and condition A4-2. Optionally, the first trigger condition may further include condition A4-3. Or the first trigger condition may only include condition A4-3. For details, reference may be made to the relevant description in the foregoing scenario A4, which will not be repeated here.

In scenario B4, since the access range of the cellular network includes the connection range of the cellular network, and the restriction of the access range of the cellular network includes: the first cell is disabled, the wireless communication device cannot access the first cell for the first time period. The cell performs the connection operation.

For example, if the first cell is a tracking area under the network of the first radio access technology, and the first radio access technology is 4G, the first cell can be added to the cell prohibition list, and a timer can be set. Before the time of the timer expires, the connection operation to the first cell cannot be performed.

In scenario B4, whether the wireless communication device can search the network is not limited in this embodiment of the present application. In a possible implementation manner, the wireless communication device may perform a network search operation on a network of any wireless access technology. In another possible implementation manner, in order to save power consumption, since the connection operation cannot be performed on the first cell, if the first cell is a cell of the first tracking area, and the first tracking area is a cell of the first radio access technology One tracking area in the network may only be used for cells other than the first cell (for example, other cells in the first tracking area other than the first cell, other first radio access technologies other than the first tracking area) The tracking area and the cell of the network of other radio access technologies) perform a network search operation, and when a suitable cell is found, and the cell is not the first cell, it can try to camp on.

In scenario B4, whether the wireless communication device can communicate with other cells other than the first cell (for example, other cells in the first tracking area other than the first cell, or other cells in the network of the first radio access technology other than the first cell) (cells in other tracking areas other than the first tracking area) to perform the connection operation, which is not limited in this embodiment of the present application.

For example, if the network of the first radio access technology is a 4G network, and the first cell is a cell of the first tracking area under the 4G network, the connection operation cannot be performed on the first cell within the first time period. Possibly, the wireless communication device may perform data transmission on cells other than the first cell (for example, other cells in the first tracking area of the 4G network other than the first cell, other cells in the 4G network except the first tracking area, etc.) Cells, and cells of 2G or 3G networks) perform network search operations, and after searching for a suitable cell, try to connect to provide services to users.

Correspondingly, in scenario B4, after it is identified in step 203 that the wireless communication device conforms to the scenario of leaving the underground garage, the restriction on the access range of the cellular network is cancelled. Access operation of a cell. In practical applications, if the wireless communication device enters the underground garage and leaves the underground garage, the wireless communication device may belong to the coverage of the first cell. In this way, once the wireless communication device leaves the underground garage, it can immediately Access to the first cell (it may be the first cell searched in advance, or the first cell searched after leaving the underground garage), so that the speed of camping on the network of the first wireless access technology can be accelerated , it can shorten the time that the wireless communication device resides on the network of the radio access technology with the lower standard priority.

In the above step 202, in a possible implementation manner, a second trigger condition may be set, and when the second trigger condition is satisfied, the wireless communication device is triggered to enable the autonomous identification strategy of the underground garage scene.

In a possible implementation manner, the second trigger condition may include one or more of the following conditions C1 and C2:

The condition C1 can be any one of the above-mentioned scene A1, scene A2, scene A3, scene A4, scene B1, scene B2, scene B3 and scene B4.

When the cellular network access range of the wireless communication device is restricted for the first time period, the autonomous identification strategy of the underground garage scene is enabled by default. That is, once the cellular network access range of the wireless communication device is restricted within the first time period, the autonomous identification strategy of the underground garage scene can be started immediately. In this way, corresponding processing can be performed on each cellular network restriction more comprehensively, so that the speed of the wireless communication device returning to the wireless access technology network can be accelerated as much as possible in each cellular network restriction.

Condition C2, it is recognized that the wireless communication device enters the underground garage.

In condition C2, when it is recognized that the wireless communication device has entered the underground garage, the autonomous identification strategy of the underground garage scene can be activated. In this way, when it is recognized that the wireless communication device has left the underground garage, the restriction on the access range of the cellular network can be cancelled in time. , in this way, the number of activations of the autonomous identification strategy for launching the underground garage scene can be reduced, so as to be more in line with the actual application scenario.

In the embodiment of the present application, various schemes may be included to identify the wireless communication device entering the underground garage, and the specific scheme can be found in the subsequent content, which will not be described here.

In the above-mentioned step 202, the autonomous identification strategy of the underground garage scene is enabled to identify whether the wireless communication device conforms to the scene of leaving the underground garage, which may be specifically based on one of the following information D1, information D2, information D3, information D4 and information D5 or more, autonomously identify whether the wireless communication device is suitable for the scene of leaving the underground garage. In a possible implementation, whether to leave the underground garage can also be identified based on other information, such as the user's instruction, or the payment information when leaving the underground garage, etc., which is not limited in this embodiment of the application. The information D1 to D5 will be introduced separately below.

Information D1: Data from gyroscope and gravity sensor.

The gyroscope is a mechanical device, the main part of which is a rotor that rotates at a very high angular speed to the rotating axis, and the rotor is installed in a bracket; an inner ring frame is added to the central axis passing through the rotor, then the gyroscope can surround the plane. The two axes are free to move; then, an outer ring frame is added to the inner ring frame; this gyroscope has two gimbal rings and can move freely around the three axes of the plane, which is a complete space gyroscope.

The working principle of a gyroscope is that the direction of the axis of rotation of a rotating object will not change unless it is affected by an external force. According to this working principle, people use it to maintain the direction, and what they make is called a gyroscope. When the gyroscope is working, it needs to give it a force to make it rotate quickly, generally it can reach hundreds of thousands of revolutions per minute, and it can work for a long time. The direction indicated by the shaft is then read in a variety of ways, and the data signal is automatically sent to the control system.

Gyroscopes are widely used in technical fields such as aviation, aerospace, navigation and communications. This is due to its two basic properties: one is fixed axis, the other is precession, both of which are based on the principle of conservation of angular momentum. In real life, the feed movement that occurs with the gyroscope occurs under the action of the gravitational moment.

Gravity sensor is a new type of sensor technology. It uses elastic sensitive elements to make cantilever displacement devices, and energy storage springs made of elastic sensitive elements to drive electrical contacts to complete the conversion from gravity changes to electrical signals. Currently, it is widely used in various mobile terminals. For example, the gravity sensor will automatically turn the screen when the mobile phone is horizontal and vertical, and can replace up and down, left and right when playing games. For example, in racing games, you can lay the mobile phone horizontally without pressing the button, and swing it left and right instead of moving left and right in the direction of the simulator game. .

Gravity sensors work on the principle of piezoelectric effect. The so-called piezoelectric effect is "for a heteropolar crystal without a center of symmetry, the external force applied to the crystal will not only deform the crystal, but also change the polarization state of the crystal and establish an electric field inside the crystal. The phenomenon of polarizing a medium is called the positive piezoelectric effect".

Gravity sensors take advantage of the internal crystal deformation caused by acceleration. Since this deformation generates a voltage, the acceleration can be converted into a voltage output by simply calculating the relationship between the generated voltage and the applied acceleration.

The gravity sensor can also measure the acceleration due to gravity and calculate the tilt angle of the device relative to the horizontal plane. By analyzing the dynamic acceleration, it is possible to analyze the way the device moves.

In a possible implementation manner, according to the data of the gyroscope and the gravity sensor, it is determined whether the movement mode of the wireless communication device satisfies the following first law:

The movement direction of the wireless communication device is converted from the oblique upward direction to the horizontal direction, and the time of continuous movement in the horizontal direction exceeds a preset time period.

If the first rule is satisfied, the wireless communication device is more likely to conform to the scene of leaving the underground garage.

Because generally, when leaving the underground garage, you need to go through an upward slope. Therefore, when it is determined from the data of the gravity sensor that the movement direction of the wireless communication device satisfies the “transition from the oblique upward direction to the horizontal direction” mentioned in the above-mentioned first law, it can be determined that the wireless communication device conforms to the scene of leaving the underground garage. More likely.

In a possible implementation manner, the movement mode can also be determined through the data of the gyroscope. For example, it can be inferred from the moving speed of the wireless communication device that the mode of the underground garage is driving, cycling or walking, etc., and then preset The correspondence between the movement mode and the time to reach the first position after driving out of the underground garage exit, wherein the distance between the first position and the underground garage exit may be a preset distance, such as 100 meters. When the exercise mode is driving, after driving out of the underground garage, it may only take 1 minute to drive another 100. When the movement mode is walking, after people leave the underground garage on foot, it may only take 3 minutes to travel 100 kilometers. It can be seen that, with different movement modes, the duration of driving the preset distance value after leaving the underground garage is also different. Therefore, in a possible implementation manner, the above-mentioned first rule may include the following content:

The movement direction of the wireless communication device is converted from the oblique upward direction to the horizontal direction, and the time of continuous movement in the horizontal direction exceeds the preset time period corresponding to the movement mode. Wherein, the preset duration is the duration corresponding to the movement mode in the corresponding relationship between the above-mentioned "movement mode and the duration of reaching the first position after driving out of the underground garage exit".

In a possible implementation manner, whether to leave the underground garage can be determined only according to the information D1. In this scenario, if the above-mentioned first rule is satisfied, it can be determined that the wireless communication device has left the underground garage. If it is not satisfied, it is determined that the underground garage has not been left.

In yet another possible implementation, other information may be combined to comprehensively determine whether it conforms to the scene of leaving the underground garage. For details, please refer to the description of the subsequent content, which will not be described here.

Information D2: satellite positioning signal.

Generally speaking, if the GPS module of the wireless communication device is turned on, the GPS signal can be quickly searched in the area covered by the GPS signal. Therefore, whether to leave the underground garage can be determined based on the satellite positioning signal.

In a possible implementation, there is no GPS signal in the underground garage or the GPS signal is weak. In this case, it is determined whether the satellite positioning signal of the wireless communication device satisfies the second rule, and the second rule is one or more of the following: item:

The satellite positioning signal of the wireless communication device starts from scratch, and the duration of the signal exceeds the preset duration;

The satellite positioning signal of the wireless communication device changes from weak to strong, and the strong signal (the strong signal can be that the signal strength of the satellite positioning signal is greater than the preset first satellite signal strength threshold, and the weak signal can be that the signal strength of the satellite positioning signal is less than the preset value. The duration of the second satellite signal strength threshold, the first satellite signal strength threshold is greater than the second satellite signal strength threshold) exceeds a preset duration.

Wherein, the preset duration in the second rule may be the duration corresponding to the movement mode in the corresponding relationship between the above-mentioned “movement mode and the duration of reaching the first position after driving out of the underground garage exit”.

If the second rule is satisfied, it is possible that the wireless communication device is likely to conform to the scene of leaving the underground garage.

In a possible implementation, whether to leave the underground garage can be determined only according to the information D2. In this scenario, if the second rule above is satisfied, it can be determined that the wireless communication device has left the underground garage. If it is not satisfied, it is determined that the underground garage has not been left.

In yet another possible implementation, other information may be combined to comprehensively determine whether it conforms to the scene of leaving the underground garage. For example, it can be determined based on the information D1 and D2. When it is determined that the first rule and the second rule above are satisfied, it can be determined that the wireless communication device has left the underground garage; otherwise, it is determined that it has not left the underground garage.

Information D3: Signal strength, signal quality or neighbor cell information of the cellular network.

Generally speaking, the signal strength of the cellular network in the underground garage is weak, the signal quality is poor, and the number of neighbor cells that can be found is small. In this case, it is determined whether the satellite positioning signal of the wireless communication device satisfies the third law. The third law is one or more of the following:

The signal strength of the cellular network of the wireless communication device ranges from weak to strong, and the duration for which the signal strength reaches the signal strength threshold exceeds a preset time period (wherein, "weak" may mean that the signal strength of the cellular network is less than the signal strength threshold, and the content It mainly reflects the change trend of signal strength. Of course, a smaller signal strength threshold can also be set. "Weak" is used to mean that the signal strength is less than the smaller signal strength threshold.).

The signal quality of the cellular network of the wireless communication device ranges from poor to excellent, and the duration for which the signal quality reaches the signal quality threshold exceeds a preset time period (wherein, "poor" may mean that the signal quality of the cellular network is less than the signal quality threshold, and this content It mainly reflects the change trend of signal quality, of course, a poor signal quality threshold can also be set, and "poor" is used to mean that the signal quality is less than the poor signal quality threshold.).

The number of searched neighbors of the wireless communication device ranges from none (or less) to more, and the duration for which the number of searched neighbors reaches the threshold of the number of neighbors exceeds a preset time period (wherein "less" may be a cellular network The signal quality is less than the threshold of the number of adjacent cells. This content mainly reflects the change trend of the number of adjacent cells. Of course, a smaller threshold of the number of adjacent cells can also be set, and "less" is used to refer to a smaller threshold of the number of adjacent cells. .

According to the searched cell identification of the wireless communication device, determine that the wireless communication device is currently in the exit area of the underground garage (the identification of the cell corresponding to the exit area of the underground garage can be stored in advance, so that the wireless communication device can be determined according to the searched identification of the cell is in the exit area of the underground garage).

Wherein, the preset duration in the third rule may be the duration corresponding to the movement mode in the corresponding relationship between the above-mentioned “movement mode and the duration of reaching the first position after driving out of the underground garage exit”.

If the third rule is satisfied, it is possible that the wireless communication device is likely to conform to the scene of leaving the underground garage.

In a possible implementation, whether to leave the underground garage may be determined only according to the information D3. In this scenario, if the above-mentioned third rule is satisfied, it may be determined that the wireless communication device has left the underground garage. If it is not satisfied, it is determined that the underground garage has not been left.

In yet another possible implementation, other information may be combined to comprehensively determine whether it conforms to the scene of leaving the underground garage. For example, the judgment may be based on one or more of the information D1, the information D2 and the information D3. For example, if the judgment is made based on the above information D1 and D3, when it is determined that the first rule and the third rule above are satisfied, it can be determined that the wireless communication device has left the underground garage; otherwise, it is determined that it has not left the underground garage.

In practical applications, generally speaking, the location of the weak signal area is generally fixed, the underground garage belongs to the weak signal area, and the tunnels and remote mountainous areas also belong to the weak signal area. You can create a cellular network map through the mobile phone’s abnormal reporting function of lost network, or manually collect the function, and mark the signal strength information of the geographical area on the cellular network map. Signal areas are marked out. Further, the latitude and longitude information and range size of a geographic area can be marked.

In a possible implementation, for example, the area of the underground garage can be marked as an area without 4G signal on the cellular network, and when it is monitored that the location of the wireless communication device leaves the area without 4G signal, it can be determined that the wireless communication device has left the underground Garage is more likely.

In another possible implementation, the time when the wireless communication device leaves the weak signal area or the no signal area can be predicted. For example, the tunnel can be marked as the no signal area, and the wireless communication device can be determined according to the historical movement track of the wireless communication device. Entering one end of the tunnel, according to the historical movement speed of the wireless communication device and the total length of the tunnel, the time required for the wireless communication device to leave the tunnel can be estimated. In this way, it can be estimated that the wireless communication device has left the no-signal area after the time is reached, and can be cancelled immediately.

For example, the weak signal area autonomous identification strategy can be enabled to identify whether it conforms to the scenario of leaving the weak signal area. If it is recognized that the wireless communication device conforms to the scenario of leaving the weak signal area, the restriction on the access range of the cellular network can be cancelled, so that the first time duration Access to previously restricted cellular networks before expiration.

It is recognized that the wireless communication device conforms to the scene of leaving the weak signal area. It can also be identified based on one or more of the information D1 to D5 in this application.

These components may be coupled by various interconnecting buses or other electrical connections.

In Fig. 4a, ANT_1 represents the first antenna, ANT_N represents the Nth antenna, and N is a positive integer greater than 1. Tx represents the transmit path, Rx represents the receive path, and different numbers represent different paths. Each path can represent a signal processing channel. Among them, FBRx represents the feedback receiving path, PRx represents the primary receiving path, and DRx represents the diversity receiving path. HB means high frequency, LB means low frequency, both refer to the relative high and low frequency. BB stands for baseband.

In addition, the wireless communication device may further include memory, such as the memory and mass storage in FIG. 4a. In addition, one or more buffers may be included in the application subsystem and the baseband subsystem, respectively. In specific implementation, memory can be divided into volatile memory (volatile memory) and non-volatile memory (non-volatile memory, NVM). Volatile memory refers to memory in which data stored inside is lost when the power supply is interrupted.
