Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, device and system. Background Art

[0002] The operator network authenticates the customer's identity through the subscriber identity module (SIM) card and encrypts the voice information of the customer during the call. The terminal device can only be used normally after the SIM card corresponding to the operator network is installed. If a terminal device is installed with multiple SIM cards, the terminal device determines the gap configuration information or the time division multiplexing (TDM) pattern configuration information. Among them, the GAP configuration information or the TDM pattern configuration information can indicate the time periods in which the terminal device can receive paging messages from other operator networks when communicating using one operator network.

[0003] However, when the terminal device moves, the GAP configuration information and TDM mode configuration information are likely to change. If the GAP configuration information or TDM mode configuration information between the terminal device and the network device is not updated in time, the terminal device cannot receive paging messages from other operators' networks in time. Summary of the invention

[0004] The embodiments of the present application provide a communication method, device and system, which can improve the success rate of terminal equipment in receiving paging messages.

[0005] In order to achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In the first aspect, an embodiment of the present application provides a communication method, and the execution subject of the method can be a terminal device or a chip used in the terminal device. The following description is taken as an example that the execution subject is a terminal device. The method includes: the terminal device determines to reselect to the first cell, or determines to reselect to the first cell, or determines that it has reselected to the first cell, and then the terminal device sends a first message to the network device. Among them, the first cell belongs to the first network. The network device belongs to the second network. The first information is determined by the terminal device. The first information includes first configuration information and / or first timing deviation information. The first configuration information includes gap GAP configuration information to be used by the terminal device or time division multiplexing TDM mode configuration information to be used. The first timing deviation information includes the downlink timing deviation between the first cell and the second cell. The second cell belongs to the second network, and the network device under the second network transmits data with the terminal device.

[0007] Here, in the second network, if the terminal device does not perform cell switching during or before performing cell reselection, the second cell is the cell accessed by the terminal device when performing data transmission with the network device in the second network. If the terminal device also performs cell switching during or before performing cell reselection, the second cell is the target cell after the terminal device switches.

[0008] That is to say, when the terminal device determines that it is to be reselected to the first cell, or determines that it has been reselected to the first cell, the terminal device can timely update the first configuration information so that the network device under the second network can timely obtain the updated first configuration information, so that after the terminal device reselects to the first cell, in the process of data transmission with the network device under the second network, it can still timely receive the paging message from the network device under the first network, thereby improving the success rate of receiving the paging message. Alternatively, when the terminal device determines that it is to be reselected to the first cell, or determines that it has been reselected to the first cell, the terminal device and the network device under the second network can timely obtain the updated first timing deviation information, and the first configuration information can be determined based on the first timing deviation information, which can also improve the success rate of receiving the paging message.

[0009] In one possible design, after the terminal device has reselected to the first cell, the GAP configuration information to be used by the terminal device includes the GAP configuration information used when the terminal device transmits data to the network device under the second network. Alternatively, after the terminal device has reselected to the first cell, the TDM mode configuration information to be used by the terminal device includes the TDM mode configuration information used when the terminal device transmits data to the network device under the second network.

[0010] In a possible design, the communication method of the embodiment of the present application also includes: the terminal device determines the first configuration information according to the downlink timing of the first cell and the downlink timing of the second cell. Alternatively, the terminal device determines the first configuration information according to the downlink timing of the cell before reselection, the downlink timing of the first cell and the downlink timing of the second cell. Alternatively, the terminal device determines the first configuration information according to the downlink timing of the cell before reselection, the downlink timing of the first cell and the downlink timing of the second cell, and the second configuration information. The second configuration information is the GAP configuration information or TDM mode configuration information used by the terminal device before reselecting to the first cell. Here, the cell before reselection refers to: under the first network, the cell where the terminal device last resides before reselecting to the first cell.

[0011] In this way, the terminal device determines the first configuration information according to the downlink timing of different cells, thereby timely updating the first configuration information, so that after the terminal device reselects the first cell, it can both transmit data with the network device under the second network and receive paging messages from the network device under the first network.

[0012] In a possible design, the communication method of the embodiment of the present application also includes: the terminal device determines the first configuration information based on the downlink timing deviation information between the first cell and the second cell. Alternatively, the terminal device determines the first configuration information based on the downlink timing deviation information between the first cell and the second cell, and the downlink timing deviation information between the second cell and the cell before reselection. Alternatively, the terminal device determines the first configuration information based on the downlink timing deviation information between the first cell and the second cell, and the second configuration information. Alternatively, the terminal device determines the first configuration information based on the downlink timing deviation information between the first cell and the second cell, the downlink timing deviation information between the second cell and the cell before reselection, and the second configuration information. The second configuration information is the GAP configuration information or TDM mode configuration information used by the terminal device before reselecting the first cell.

[0013] In this way, the terminal device determines the first configuration information based on the downlink timing deviation information between different cells, thereby timely updating the first configuration information, so that after the terminal device reselects the first cell, it can both transmit data with the network device under the second network and receive paging messages from the network device under the first network.

[0014] In a possible design, the communication method of the embodiment of the present application further includes: when the first condition is met, the terminal device determines the first information. The first condition includes at least one of the following: the terminal device has been stationed in the first cell; the downlink timing of the cell before the terminal device reselects is different from the downlink timing of the first cell; the downlink timing deviation between the downlink timing of the cell before the terminal device reselects and the downlink timing of the first cell is greater than a first threshold; the network device to which the cell before the terminal device reselects belongs is different from the network device to which the first cell belongs.

[0015] In this way, the terminal device determines the first information only when certain conditions are met, so as to avoid the terminal device frequently updating the first information, and also avoid the terminal device frequently sending the first information to the network device under the second network, thereby saving air interface resources.

[0016] In a possible design, the communication method of the embodiment of the present application further includes: the terminal device obtains the downlink timing of the cell before reselection. If the terminal device determines that there is a cell with the same downlink timing as the cell before reselection, the cell with the same downlink timing as the cell before reselection is used as the first cell. Or the terminal device uses the cell whose downlink timing deviation from the cell before reselection is less than or equal to the first threshold as the first cell.

[0017] In this way, when the terminal device reselects a cell, the downlink timing between the cells before and after the terminal device reselects can be made the same or close, so as to reduce the probability of failure to receive a paging message due to the difference in downlink timing of the cells.

The first configuration information includes GAP configuration information to be used by the terminal device or TDM mode configuration information to be used.

[0019] In this way, the terminal device can obtain the first configuration information based on the first timing deviation information, so that after the terminal device reselects the first cell, it can use the first configuration information to transmit data with the network device under the second network, thereby ensuring that the terminal device can receive the paging message of the network device under the first network in time.

[0020] In a possible design, the communication method of the embodiment of the present application further includes: the terminal device receives a first confirmation message from the network device, and the first confirmation message is used to indicate that the network device has received the first information. In this way, the terminal device can know the reception status of the network device for the first information.

[0026] That is to say, when the terminal device determines to be switched to the target cell, or determines to switch to the target cell, the terminal device can timely update the first configuration information so that the target network device under the second network can obtain the updated first configuration information in time, so that after the terminal device switches to the target cell, during the process of data transmission with the target network device under the second network, the terminal device can still receive the paging message from the network device under the first network in time, thereby improving the success rate of receiving the paging message. Alternatively, when the terminal device determines to be switched to the target cell, or determines to switch to the target cell, the terminal device and the network device under the second network can obtain the updated first timing deviation information in time, and the first configuration information can be determined based on the first timing deviation information, which can also improve the success rate of receiving the paging message.

[0027] In a possible design, the communication method of the embodiment of the present application also includes: the terminal device determines the first configuration information according to the downlink timing of the first cell and the downlink timing of the target cell.

[0104] The terms "first" and "second" in the specification and drawings of the present application are used to distinguish different objects, or to distinguish different treatments of the same object, rather than to describe the specific order of objects. In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes other steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices. In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0105] First, let’s introduce the technical terms involved in the relevant technologies:

[0106] 1. Cell reselection

[0107] For a terminal device in an idle state, the terminal device monitors the signal quality of neighboring cells and the current cell to select a cell with the best signal quality to provide service signals. This process is called cell reselection. When the signal quality and level of a neighboring cell meet certain conditions, the terminal device accesses the cell and resides there.

[0108] 2. Cell handover

[0109] For a terminal device in a connected state, when the terminal device moves from one cell to another, or due to network reasons, business load adjustment, equipment failure, etc., the terminal device may switch from the source cell to the target cell to ensure the continuity of communication between the terminal device and the network device. The above process is called "cell switching".

[0110] The cell that the terminal device accesses before the handover due to mobility, network reasons, business load adjustment, equipment failure, etc. is described as the "source cell". The cell that the terminal device accesses after the handover due to mobility, network reasons, business load adjustment, equipment failure, etc. is described as the "target cell". The network device corresponding to the source cell is described as the "source network device" and can also be described as the first network device. The network device corresponding to the target cell is described as the "target network device" and can also be described as the second network device.

[0111] 3. Multi-card terminal equipment

[0112] A multi-card type terminal device, which may also be described as a "multi-card terminal", refers to a terminal device installed with multiple subscriber identification module (SIM) cards, and a user may choose to use any one of the SIM cards for communication.

[0113] In the case where two SIM cards are installed in the terminal device, if the terminal device includes a radio frequency interface (Rx) for receiving and a radio frequency interface (Tx) for transmitting, the terminal device can only transmit data with the network device under one network. If the terminal device includes two radio frequency interfaces (Rx) for receiving and two radio frequency interfaces (Tx) for transmitting, the terminal device can monitor the paging messages of the two networks at the same time, and transmit data with the network devices under the two networks respectively at the same time. If the terminal device includes two radio frequency interfaces (Rx) for receiving and one radio frequency interface (Tx) for transmitting, it is very difficult for the terminal device to transmit data in the two networks at the same time, and it is impossible to receive the paging message of one of the two networks in time. For example, when the terminal device transmits data with the network device through SIM1 (such as voice service, map navigation, etc.), it cannot receive the paging message on SIM2. Among them, the network to which SIM1 and SIM2 belong can be the same operator network or different operator networks.

[0114] In order to enable the terminal device to receive the paging message of network device 2 while transmitting data with network device 1 (such as voice conference, map navigation, bank hotline and other voice services through network device 1), the terminal device determines the configuration information according to the timing deviation and paging occasion (PO) of network device 1 and network device 2, and then sends the configuration information to network device 1. The configuration information includes gap configuration information or time division multiplexing (TDM) mode configuration information. If the terminal device includes a radio frequency interface for receiving, the network device 1 stops scheduling the terminal device on the transmission resources indicated by the configuration information, and the terminal device can receive the paging message of network device 2 on the transmission resources indicated by the configuration information. If the terminal device includes multiple radio frequency interfaces for receiving, the network device 1 reduces the scheduling of some radio frequency interfaces for receiving on the transmission resources indicated by the configuration information, so that the terminal device receives the paging message of network device 2 on the transmission resources indicated by the configuration information. The network device 1 and the network device 2 may belong to the same operator network or different operator networks. Network device 1 and network device 2 each have their own downlink timing, and the downlink timing between the two can be the same or different. The time unit of the downlink timing can be a superframe number, a frame number, a time slot, a symbol, a second, a millisecond, a microsecond, or a nanosecond, etc., which is not limited in the embodiment of the present application.

[0115] For a multi-card type terminal device, under the first network, the terminal device is in an idle state, listening to paging messages from the network device under the first network. Under the second network, the terminal device is in a connected state, transmitting data with the network device under the second network. The scenarios in the embodiments of the present application are all this scenario. In this scenario, "the terminal device performs cell reselection" means: the terminal device performs cell reselection under the first network. The cell to which the terminal device reselects is described as the "first cell". "The cell before the terminal device reselects" means: under the first network, the cell where the terminal device last resides before reselecting to the first cell. "The terminal device performs cell switching" means: the terminal device performs cell switching under the second network. Here, the first network and the second network can be the same network operator or different network operators.

[0116] If the terminal device performs cell reselection in the first network, there is a high probability that the downlink timing between the first cell reselected by the terminal device and the cell before reselection will change. If the downlink timing between the first cell and the cell before reselection differs greatly, the transmission resources used to transmit data and the transmission resources used for paging messages may overlap (such as complete overlap or partial overlap), thus causing the terminal device to be unable to receive the paging message of the first network in a timely manner during data transmission with the network device in the second network. Similarly, if the terminal device performs cell switching in the second network, if the downlink timing between the source cell and the target cell differs greatly, it may also cause the terminal device to be unable to receive the paging message of the first network in a timely manner during data transmission with the network device in the second network.

[0117] In view of this, an embodiment of the present application provides a communication method, and the communication method of the embodiment of the present application is applicable to various communication systems. The communication method provided in the embodiment of the present application can be applied to a long term evolution (LTE) system, or a fifth-generation (5G) communication network, or other similar networks, or other future networks. Figure 1 The schematic diagram of the architecture of a communication system applicable to the communication method of the embodiment of the present application is shown in FIG. 1 , and the communication system may include a terminal device 10 and a network device 11. The terminal device 10 is wirelessly connected to the network device 11. The number of the terminal devices 10 may be one or more, and the number of the network devices 11 may also be one or more. Figure 1 Only one network device and two terminal devices are shown. Figure 1 In the figure, an ellipse represents a cell. Figure 1 It is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the communication method in the embodiment of the present application.

[0118] The terminal device 10, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice / data connectivity to users, for example, a handheld device or a vehicle-mounted device with a wireless connection function. The terminal device can specifically be: a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, or a wireless terminal in smart home, a terminal device in a future 5G communication network or a communication network after 5G, etc., and the embodiments of the present application are not limited to this.

[0119] The network device 11 is a device in a wireless communication network, such as a radio access network (RAN) node that connects the terminal device 10 to the wireless communication network. At present, some examples of RAN nodes are: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wifi) access point (AP), or network side equipment in future 5G communication network or communication network after 5G, etc.

[0120] The communication system and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0121] The communication method provided in the embodiments of the present application is described in detail below.

[0122] It should be noted that the message names between the network elements or the names of the parameters in the messages in the following embodiments of the present application are only examples, and other names may be used in the specific implementation. They are uniformly described here and will not be repeated below.

[0123] The embodiment of the present application provides a communication method, which is applied in a cell reselection process. Figure 2 , the communication method comprises the following steps:

[0124] S200. The terminal device determines the first cell.

[0125] The first cell belongs to the first network. The terminal device performs cell reselection in the first network, and the first cell is the cell reselected by the terminal device in the first network. There are many ways to implement S200, such as but not limited to the following ways:

[0126] Step 1: The terminal device obtains the downlink timing of the cell before reselection.

[0127] Step 2: If the terminal device determines that there is a cell with the same downlink timing as the cell before reselection, the cell with the same downlink timing as the cell before reselection is used as the first cell. Alternatively, the terminal device uses a cell with a downlink timing deviation from the cell before reselection that is less than or equal to a first threshold as the first cell.

[0128] That is, when the terminal device determines that there is a cell with the same downlink timing as the cell before reselection, the terminal device prioritizes the cell with the same downlink timing as the cell before reselection as the first cell. When the terminal device determines that there is no cell with the same downlink timing as the cell before reselection, the terminal device prioritizes the cell whose downlink timing deviation from the cell before reselection is less than or equal to the first threshold as the first cell.

[0129] The first threshold may be a value configured by a network device in the first network, or may be a value configured by a network device in the second network.

[0130] In this way, when the terminal device reselects a cell, the downlink timing between the cells before and after the terminal device reselects can be made the same or close, so as to reduce the probability of failure to receive a paging message due to the difference in downlink timing of the cells.

[0131] S201. The terminal device determines a first event.

[0132] The first event includes any one of the following: the terminal device determines to reselect to the first cell, or the terminal device determines to reselect to the first cell, or the terminal device has reselected to the first cell.

[0133] Here, "the terminal device determines that the cell to be reselected is the first cell" may refer to: the process in which the terminal device determines that the cell to be reselected is the first cell, or after the terminal device determines that the cell to be reselected is the first cell, but has not yet reselected the first cell.

[0134] “The terminal device determines to reselect to the first cell” may mean that after the terminal device determines that the cell to be reselected is the first cell, it is about to perform a reselection operation or is performing a reselection operation, but fails to successfully reside in the first cell.

[0135] “The terminal device has reselected the first cell” may mean that the terminal device has successfully camped on the first cell.

[0136] S202: The terminal device determines the first information.

[0137] Here, "the terminal device determines the first information" may mean: after the terminal device sends the first information to the network device under the second network, the network device under the second network can use the first information to obtain the resources used for data transmission with the terminal device, and the network device under the second network does not modify the first information. Alternatively, "the terminal device determines the first information" may also mean: after the terminal device recommends the first information to the network device under the second network, the network device under the second network uses the first information as auxiliary information or reference information, first modifies the first information, and obtains the resources used for data transmission with the terminal device based on the modified first information.

[0138] The first information includes the following three situations:

[0139] Case 1: The first information includes the first configuration information. The first configuration information includes the GAP configuration information to be used by the terminal device or the TDM mode configuration information to be used. Here, the GAP configuration information to be used by the terminal device refers to: after the terminal device reselects to the first cell, the GAP configuration information used when the terminal device and the network device under the second network perform data transmission. The TDM mode configuration information to be used by the terminal device refers to: after the terminal device reselects to the first cell, the TDM mode configuration information used when the terminal device and the network device under the second network perform data transmission. The first network and the second network may be the same network operator or different network operators.

[0140] There are many ways for the terminal device to determine the first configuration information, such as but not limited to the following seven ways:

[0141] Method 1: The terminal device determines the first configuration information according to the downlink timing of the first cell and the downlink timing of the second cell.

[0142] The second cell belongs to the second network. In the second network, if the terminal device does not perform cell switching during or before executing S201, the second cell is the cell accessed by the terminal device when performing data transmission with the network device in the second network. If the terminal device also performs cell switching during or before executing S201, the second cell is the target cell after the terminal device switches.

[0143] Exemplarily, the terminal device can determine the downlink timing deviation between the first cell and the second cell based on the downlink timing of the first cell and the downlink timing of the second cell, and then determine the first configuration information based on the time slot in which the terminal device needs to receive the paging message and / or system information in the first cell. For example, if the terminal device receives the paging message in time slot 4 of the first cell, and the downlink timing deviation between the first cell and the second cell is "+1" time slot, the terminal device can determine that the first configuration information (such as the GAP configuration information used in the second cell) is time slot 5, that is, at the moment of time slot 5 of the second cell, the terminal device receives the paging message from the network device corresponding to the first cell. The determination of other TDM mode configurations is similar, except that the number of determined time slots is different.

[0144] Exemplarily, the terminal device may also determine the downlink timing deviation between the first cell and the second cell according to the downlink timing of the first cell and the downlink timing of the second cell, and then use the downlink timing deviation between the first cell and the second cell to adjust the second configuration information to determine the first configuration information. The second configuration information is the GAP configuration information or TDM mode configuration information used by the terminal device before reselecting to the first cell.

[0145] In addition, the implementation method for determining the first configuration information described in the first method may also be used as a possible implementation method for determining the first configuration information according to the downlink timing in the second to seventh methods.

[0146] Method 2: The terminal device determines the first configuration information according to the downlink timing of the cell before reselection, the downlink timing of the first cell and the downlink timing of the second cell.

[0147] Among them, the relevant instructions for the second community can be found in Method 1, which will not be repeated here.

[0148] Exemplarily, the terminal device may determine the downlink timing deviation 1 based on the downlink timing of the first cell and the downlink timing of the second cell, and the terminal device may determine the downlink timing deviation 2 based on the downlink timing of the cell before reselection and the downlink timing of the first cell. The terminal device then determines the first configuration information based on the time slot in which the terminal device needs to receive the paging message and / or system information in the cell before reselection. For example, if the terminal device receives the paging message in time slot 4 of the cell before reselection, and the downlink timing deviation 1 and the downlink timing deviation 2 are "+1" time slots, the terminal device may determine that the first configuration information (such as the GAP configuration information used in the second cell) is time slot 6, that is, at the moment of time slot 6 of the second cell, the terminal device receives the paging message from the network device corresponding to the first cell. The determination of other TDM mode configurations is similar, except that the number of determined time slots is different. Alternatively, refer to method seven or the example in method seven.

[0149] Method three: The terminal device determines the first configuration information according to the downlink timing of the cell before reselection, the downlink timing of the first cell, the downlink timing of the second cell, and the second configuration information.

[0150] For the relevant description of the second configuration information and the second cell, please refer to Method 1, which will not be repeated here. For specific examples, please refer to Method 7 or the examples in Method 7.

[0151] Method 4: The terminal device determines the first configuration information according to the downlink timing deviation information between the first cell and the second cell.

[0152] Among them, the relevant instructions for the second community can be found in Method 1, which will not be repeated here.

[0153] For example, if the terminal device receives a paging message in time slot 4 of the first cell, and the downlink timing deviation between the first cell and the second cell is "+1" time slot, the terminal device can determine that the first configuration information (such as the GAP configuration information used in the second cell) is time slot 5, that is, at time slot 5 of the second cell, the terminal device receives a paging message from the network device corresponding to the first cell.

[0154] Alternatively, the terminal device uses the downlink timing deviation between the first cell and the second cell to adjust the second configuration information to determine the first configuration information. The second configuration information is the GAP configuration information or TDM mode configuration information used by the terminal device before reselecting to the first cell. Alternatively, refer to method seven or the example in method seven.

[0155] Method 5: The terminal device determines the first configuration information according to the downlink timing deviation information between the first cell and the second cell, and the downlink timing deviation information between the second cell and the cell before reselection.

[0156] For the relevant description of the second cell, please refer to Method 1, which will not be repeated here. For specific examples, please refer to Method 7 or the examples in Method 7.

[0157] Method six: The terminal device determines the first configuration information according to the downlink timing deviation information between the first cell and the second cell, and the second configuration information.

[0158] For the relevant description of the second configuration information and the second cell, please refer to Method 1, which will not be repeated here. For specific examples, please refer to Method 7 or the examples in Method 7.

[0159] Method seven: The terminal device determines the first configuration information according to the downlink timing deviation information between the first cell and the second cell, the downlink timing deviation information between the second cell and the cell before reselection, and the second configuration information.

[0160] Exemplarily, the terminal device determines that downlink timing deviation 1 is 20ms based on the downlink timing of the cell before reselection and the downlink timing of the second cell. The terminal device determines that downlink timing deviation 2 is 100ms based on the downlink timing of the first cell and the downlink timing of the second cell. The terminal device then determines the first configuration information based on the two downlink timing deviations (i.e., 20ms and 100ms) and the second configuration information.

[0161] Among them, the relevant instructions on the second configuration information and the second cell can be found in Method 1, which will not be repeated here.

[0162] Optionally, when a certain condition is met, the terminal device determines the first configuration information. Here, the condition for the terminal device to determine the first configuration information is recorded as "condition 1", and condition 1 includes at least one of the following:

[0163] First, the terminal device has resided in the first cell.

[0164] Second, the downlink timing of the cell before the terminal device reselects is different from the downlink timing of the first cell.

[0165] Third, a downlink timing deviation between the downlink timing of the cell before the terminal device reselects and the downlink timing of the first cell is greater than a first threshold.

[0166] Fourth, the network device to which the cell before the terminal device reselects belongs is different from the network device to which the first cell belongs.

[0167] In this way, the terminal device determines the first configuration information only when certain conditions are met, so as to avoid the terminal device frequently updating the first configuration information, and also avoid the terminal device frequently sending the first configuration information to the network device under the second network, thereby saving air interface resources.

[0168] Case 2: The first information includes the first timing deviation information. The first timing deviation information includes the downlink timing deviation between the first cell and the second cell. Here, the relevant description of the second cell can refer to method 1, which is not repeated here. The first timing deviation information is determined by the terminal device based on the downlink timing of the first cell and the downlink timing of the second cell.

[0169] Optionally, when a certain condition is met, the terminal device determines the first timing deviation information. Here, the condition for the terminal device to determine the first timing deviation information is recorded as "condition 2", and condition 2 includes at least one of the following:

[0170] First, the terminal device has resided in the first cell.

[0171] Second, the downlink timing of the cell before the terminal device reselects is different from the downlink timing of the first cell.

[0172] Third, the network device to which the cell before the terminal device reselects belongs is different from the network device to which the first cell belongs.

[0173] In this way, the terminal device determines the first timing deviation information only when certain conditions are met, so as to avoid the terminal device frequently updating the first timing deviation information, and also avoid the terminal device frequently sending the first timing deviation information to the network device under the second network, thereby saving air interface resources.

[0174] Further, after the terminal device determines the first timing deviation information, the terminal device determines the first configuration information according to the first timing deviation information. For example, the terminal device adjusts the second configuration information according to the first timing deviation information to obtain the first configuration information.

[0175] In this way, the terminal device can obtain the first configuration information based on the first timing deviation information, so that after the terminal device reselects the first cell, it can use the first configuration information to transmit data with the network device under the second network, thereby ensuring that the terminal device can receive the paging message of the network device under the first network in time.

[0176] Case 3: The first information includes first configuration information and first timing deviation information. The first configuration information can refer to the relevant description in case 1, and the first timing deviation information can refer to the relevant description in case 2, which will not be repeated here.

[0177] S203: The terminal device sends the first information to the network device. Correspondingly, the network device receives the first information from the terminal device.

[0178] The network device belongs to the second network and performs data transmission with the terminal device in the second network.

[0179] S204: The network device determines resources for data transmission between the terminal device and the network device according to the first information.

[0180] Exemplarily, if the first information includes the first configuration information, the network device determines the resources for data transmission between the terminal device and the network device, such as the time domain resources for data transmission between the terminal device and the network device, based on the first configuration information. Here, in the case where the terminal device determines the first configuration information, the network device does not adjust the first configuration information, and determines the resources for data transmission between the terminal device and the network device based on the first configuration information from the terminal device. In the case where the terminal device recommends the first configuration information, the network device may first adjust the first configuration information from the terminal device, and then determine the resources for data transmission between the terminal device and the network device based on the adjusted first configuration information.

[0181] If the first information includes the first timing deviation information, the network device determines the first configuration information according to the first timing deviation information. For example, the network device uses the first timing deviation information to adjust the second configuration information to obtain the first configuration information, so that the network device and the terminal device that reselects to the first cell can perform data transmission, and also ensure that the terminal device receives the paging message of the network device under the first network in a timely manner. Here, similarly, in the case where the terminal device determines the first timing deviation information, the network device does not adjust the first timing deviation information, and determines the resources for data transmission between the terminal device and the network device according to the first timing deviation information from the terminal device. In the case where the terminal device recommends the first timing deviation information, the network device can first adjust the first timing deviation information from the terminal device, and then determine the resources for data transmission between the terminal device and the network device according to the adjusted first timing deviation information.

[0182] S205: The network device sends a first confirmation message to the terminal device. Correspondingly, the terminal device receives the first confirmation message from the network device.

[0183] The first confirmation message is used to indicate that the network device has received the first information.

[0184] It should be noted that the network device may first execute S204 and then execute S205. The network device may also first execute S205 and then execute S204. The network device may also execute S204 and S205 simultaneously. The embodiment of the present application does not limit the execution order of S204 and S205.

[0185] The communication method provided in the embodiment of the present application is that when the terminal device determines that it is to be reselected to the first cell, or the terminal device determines to be reselected to the first cell, or the terminal device has been reselected to the first cell, the terminal device can timely update the first configuration information so that the network device under the second network can timely obtain the updated first configuration information, so that after the terminal device reselects to the first cell, in the process of data transmission with the network device under the second network, it can still timely receive the paging message from the network device under the first network, thereby avoiding the problem of "paging message reception failure" caused by the failure to update the configuration information in time in the prior art. Alternatively, when the terminal device determines that it is to be reselected to the first cell, or the terminal device determines to be reselected to the first cell, or the terminal device has been reselected to the first cell, the terminal device and the network device under the second network can timely obtain the updated first timing deviation information, and the first configuration information can be determined based on the first timing deviation information, which can also avoid the problem of "paging message reception failure" caused by the failure to update the configuration information in time in the prior art.

[0186] The embodiment of the present application provides another communication method, which is applied in a cell switching process. In the cell switching scenario, it mainly involves a terminal device, a source network device and a target network device. The first configuration information can be determined by any one of the terminal device, the source network device and the target network device. Below, three examples are used for illustration.

[0187] Example 1: The first configuration information is determined by the terminal device.

[0188] See also Figure 3 , Figure 4 or Figure 5 The communication method of the embodiment of the present application includes the following steps:

[0189] S301. The terminal device determines a first event.

[0190] The first event includes any one of the following: the terminal device determines to switch to the target cell, or the terminal device switches to the target cell. The target cell belongs to the second network.

[0191] Here, "the terminal device determines the target cell to be switched to" may mean: the terminal device has determined a potential target cell, but has not switched to the target cell. Alternatively, the terminal device has determined a target cell to be switched to, but has not switched to the target cell. Among them, the "potential target cell" is determined by the terminal device based on information such as the reference signal reception quality of the neighboring cell, and may be one or more neighboring cells in the measurement report. "The terminal device switches to the target cell" may mean: the terminal device has switched to the target cell.

[0192] S302: The terminal device determines first configuration information.

[0193] The first configuration information includes the GAP configuration information or TDM mode configuration information used by the terminal device after switching to the target cell. That is, the first configuration information is the GAP configuration information or TDM mode configuration information used by the terminal device when performing data transmission with the target network device under the second network after switching to the target cell.

[0194] "The terminal device determines the first configuration information" may mean: after the target network device obtains the first configuration information, the target network device can use the first configuration information to obtain the resources used for data transmission with the terminal device, and the target network device does not modify the first configuration information. Alternatively, "the terminal device determines the first configuration information" may also mean: after the terminal device recommends the first configuration information to the target network device under the second network, the target network device uses the first configuration information as auxiliary information or reference information, and may first modify the first configuration information, and obtain the resources used for data transmission with the terminal device according to the modified first configuration information.

[0195] There are many specific implementation processes for "the terminal device determines the first configuration information". According to "whether the terminal device performs cell reselection in the first network", it is mainly divided into the following two scenarios:

[0196] Scenario 1: During or before the execution of S301, the terminal device does not reselect a cell in the first network, that is, the cell where the terminal device resides in the first network does not change. In this scenario, the specific implementation process of S302 may be, for example, but not limited to, the following ten methods:

[0197] Method 1: The terminal device determines the first configuration information according to the downlink timing of the cell where the terminal device resides in the first network and the downlink timing of the target cell.

[0198] Here, when the terminal device knows the downlink timing of the cell residing in the first network and the downlink timing of the target cell in the second network, the terminal device can determine the first configuration information so that the terminal device can both transmit data with the network device in the second network and receive paging messages from the network device in the first network in a timely manner.

[0199] Exemplarily, the terminal device may determine the downlink timing deviation 1 based on the downlink timing of the cell where the terminal device resides under the first network and the downlink timing of the target cell, and then determine the first configuration information based on the time slot in which the terminal device resides under the first network and needs to receive the paging message and / or system information. For example, if the terminal device receives the paging message in time slot 4 of the cell where the terminal device resides under the first network, and the downlink timing deviation 1 is "+1" time slot, the terminal device may determine that the first configuration information (such as the GAP configuration information used in the target cell) is time slot 5, that is, at the moment of time slot 5 of the target cell, the terminal device receives the paging message from the network device of the first network. The determination of other TDM mode configurations is similar, except that the number of determined time slots is different.

[0200] Exemplarily, the terminal device may also determine the downlink timing deviation 1 according to the downlink timing of the cell where the terminal device resides in the first network and the downlink timing of the target cell, and then use the downlink timing deviation 1 to adjust the second configuration information to determine the first configuration information. The second configuration information is the GAP configuration information or TDM mode configuration information used by the terminal device in the source cell.

[0201] In addition, the implementation method for determining the first configuration information described in Method 1 may also be used as a possible implementation method for determining the first configuration information according to downlink timing in Methods 2 to 10.

[0202] Method 2: The terminal device determines the first configuration information according to the downlink timing of the source cell and the downlink timing of the target cell.

[0203] The source cell and the target cell belong to the second network.

[0204] Exemplarily, if the downlink timing deviation between the cell where the terminal device resides in the first network and the source cell in the second network is known, the terminal device can determine the downlink timing of the cell where the terminal device resides in the first network in combination with the downlink timing of the source cell in the second network. In this way, the terminal device can determine the first configuration information based on the downlink timing of the cell where the terminal device resides in the first network and the downlink timing of the target cell in the second network.

[0205] Method three: The terminal device determines the first configuration information according to the downlink timing of the source cell and the downlink timing of the target cell, as well as the downlink timing of the cell where the terminal device resides in the first network.

[0206] Exemplarily, the terminal device may determine the downlink timing deviation 1 based on the downlink timing of the source cell and the downlink timing of the target cell, determine the downlink timing deviation 2 based on the downlink timing of the cell where the terminal device resides under the first network and the downlink timing of the source cell, and then determine the first configuration information based on the time slot in which the cell where the terminal device resides under the first network needs to receive the paging message and / or system information. For example, if the terminal device receives the paging message in time slot 4 of the cell where the terminal device resides under the first network, and the downlink timing deviation 1 and the downlink timing deviation 2 are "+1" time slots, the terminal device may determine the first configuration information (such as the GAP configuration information used in the target cell) to be time slot 6, that is, at the moment of time slot 6 of the target cell, the terminal device receives the paging message from the network device of the first network. The determination of other TDM mode configurations is similar, except that the number of determined time slots is different.

[0207] Method 4: The terminal device determines the first configuration information according to the downlink timing of the source cell and the downlink timing of the target cell, as well as the second configuration information.

[0208] The second configuration information is the GAP configuration information or TDM mode configuration used by the terminal device in the source cell.

[0209] Exemplarily, the terminal device obtains the downlink timing deviation between the source cell and the target cell based on the downlink timing of the source cell and the downlink timing of the target cell, and then adjusts the second configuration information based on the downlink timing deviation between the source cell and the target cell to obtain the first configuration information.

[0210] Method 5: The terminal device determines the first configuration information according to the downlink timing of the source cell, the downlink timing of the target cell, the downlink timing of the second cell, and the second configuration information.

[0211] The second cell is a service cell where the terminal device resides when no cell reselection is performed in the first network.

[0212] Exemplarily, the terminal device determines a timing deviation adjustment amount according to the downlink timing of the source cell, the downlink timing of the target cell, and the downlink timing of the second cell, and then adjusts the second configuration information according to the obtained timing deviation adjustment amount to obtain the first configuration information.

[0213] Mode 6: The terminal device determines the first configuration information according to the downlink timing deviation information between the source cell and the target cell. Here, the specific example can refer to Mode 3 or the example in Mode 3.

[0214] Method seven: The terminal device determines the first configuration information based on the downlink timing deviation information between the cell in which the terminal device resides in the first network and the target cell.

[0215] Exemplarily, the terminal device adjusts the second configuration information according to the downlink timing deviation information between the cell in which the terminal device resides in the first network and the target cell to obtain the first configuration information.

[0216] Method eight: The terminal device determines the first configuration information according to the downlink timing deviation information between the second cell and the source cell, and the downlink timing deviation information between the second cell and the target cell.

[0217] For the introduction of the second cell, please refer to the relevant description of method 5, which will not be repeated here. For specific examples, please refer to method 10 or the example of method 10.

[0218] Method nine: The terminal device determines the first configuration information based on the downlink timing deviation information between the source cell and the target cell, and the second configuration information.

[0219] Exemplarily, the terminal device adjusts the second configuration information according to the downlink timing deviation information between the source cell and the target cell to obtain the first configuration information. For the introduction of the second configuration information, please refer to the relevant description of the fourth method, which will not be repeated here.

[0220] Method 10: The terminal device determines the first configuration information based on the downlink timing deviation information between the second cell and the source cell, the downlink timing deviation information between the second cell and the target cell, and the second configuration information.

[0221] Among them, for the introduction of the second configuration information, please refer to the relevant instructions in method 4, and for the introduction of the second cell, please refer to the relevant instructions in method 5, which will not be repeated here.

[0222] Exemplarily, the downlink timing deviation 1 between the second cell and the source cell is 20ms, and the downlink timing deviation 2 between the second cell and the target cell is 100ms. The terminal device then determines the first configuration information based on the two downlink timing deviations (ie, downlink timing deviation 1 and downlink timing deviation 2) and the second configuration information.

[0223] Optionally, in scenario 1, if a certain condition is met, the terminal device determines the first configuration information. Here, the condition for the terminal device to determine the first configuration information is recorded as "condition 3", and condition 3 includes at least one of the following:

[0224] First, the downlink timing of the source cell is different from the downlink timing of the target cell.

[0225] Second, the downlink timing deviation between the downlink timing of the source cell and the downlink timing of the target cell is greater than a first threshold value. The first threshold value may be a value configured by a network device in the first network, or a value configured by a source network device or a target network device in the second network.

[0226] Third, the network equipment to which the source cell belongs is different from the network equipment to which the target cell belongs.

[0227] In this way, the terminal device determines the first configuration information only when at least one of condition 3 is met, so as to avoid the terminal device frequently updating the first configuration information, and also avoids the terminal device frequently sending the first configuration information to the network device under the second network, thereby saving air interface resources.

[0228] Scenario 2: During or before the execution of S301, the terminal device performs cell reselection in the first network and reselects to the first cell. In this scenario, the specific implementation process of S302 may be, for example but not limited to, the following methods:

[0229] The terminal device determines the first configuration information according to the downlink timing of the first cell and the downlink timing of the target cell.

[0230] Here, when the terminal device knows the downlink timing of the first cell reselected under the first network and the downlink timing of the target cell under the second network, the terminal device can determine the first configuration information so that the terminal device can both transmit data with the target network device under the second network and receive paging messages from the network device under the first network in a timely manner.

[0231] Optionally, in scenario 2, if a certain condition is met, the terminal device determines the first configuration information. Here, the condition for the terminal device to determine the first configuration information is recorded as "condition 4", and condition 4 includes at least one of the following:

[0232] First, the downlink timing of the first cell is different from the downlink timing of the target cell.

[0233] Second, a downlink timing deviation between the downlink timing of the first cell and the downlink timing of the target cell is greater than a first threshold.

[0234] Third, the network equipment to which the first cell belongs is different from the network equipment to which the target cell belongs.

[0235] In this way, the terminal device determines the first configuration information only when at least one of condition 4 is met, so as to avoid the terminal device frequently updating the first configuration information. It also avoids the terminal device frequently sending the first configuration information to the network device under the second network, saving air interface resources.

[0236] It should be noted that before the terminal device executes S302, since the terminal device has not executed S306, that is, the terminal device has not received the switching command from the source network device, the "target cell" in the relevant description of S302 refers to the "potential target cell", that is, the cell determined by the terminal device based on information such as the reference signal reception quality of the neighboring cell.

[0237] Before the terminal device executes S302 and before executing S306, after the terminal device determines the first configuration information, the terminal device can transmit the first configuration information to the target network device through two transmission paths. The two transmission paths of the first configuration information are described below:

[0238] In the first transmission pathway, see Figure 3 , the terminal device transmits the first configuration information to the target network device through the source network device, that is, after the terminal device executes S302, it executes S303:

[0239] S303: The terminal device sends first configuration information to the source network device. Correspondingly, the source network device receives the first configuration information from the terminal device.

[0240] The first configuration information may be carried in a measurement report or in other messages so as to be transmitted from the terminal device to the source network device.

[0241] Optionally, after the source network device confirms receipt of the first configuration information, the source network device sends a first confirmation message to the terminal device. Correspondingly, the terminal device receives the first confirmation message from the source network device. The first confirmation message is used to indicate that the source network device has received the first configuration information.

[0242] S304: The source network device sends a switching request message to the target network device. Correspondingly, the target network device receives the switching request message from the source network device.

[0243] The process of the source network device determining the target cell and the target network device is as follows: the terminal device sends a measurement report to the source network device. Correspondingly, the source network device receives the measurement report from the terminal device. The measurement report includes information such as the reference signal reception quality of the source cell and the reference signal reception quality of the neighboring cell. The source network device determines the target cell to which the terminal device is to be switched and the target network device corresponding to the target cell based on the measurement report.

[0244] Here, the source network device and the target network device belong to the second network. The switching request message is used to request that the terminal device be switched to the target network device. In the case where the source network device does not execute S303, the switching request message does not include the first configuration information. In the case where the source network device executes S303, the switching request message also includes the first configuration information. After the target network device obtains the first configuration information, S309 is executed based on the first configuration information.

[0245] S305: The target network device sends a switching confirmation message to the source network device. Correspondingly, the source network device receives the switching confirmation message from the target network device.

[0246] The switching confirmation message is used to confirm switching the terminal device to the target network device.

[0247] S306: The source network device sends a switching command to the terminal device. Correspondingly, the terminal device receives the switching command from the source network device.

[0248] The handover command includes indication information, which is used to indicate the target cell to be handed over by the terminal device.

[0249] S307. In response to the switching command, the terminal device and the target network device perform a random access process.

[0250] The specific implementation process of the random access (RA) process can be found in the prior art and will not be described in detail here.

[0251] In the second transmission pathway, see Figure 4 , the terminal device sends the first configuration information to the target network device, that is, after the terminal device executes S302, it does not execute S303, but executes S308:

[0252] S308: The terminal device sends the first configuration information to the target network device. Correspondingly, the target network device receives the first configuration information from the terminal device.

[0253] Optionally, after the target network device confirms receipt of the first configuration information, the target network device sends a first confirmation message to the terminal device. Accordingly, the terminal device receives the first confirmation message from the target network device. The first confirmation message is used to indicate that the target network device has received the first configuration information. After the target network device receives the first configuration information from the terminal device, the target network device performs S309 based on the first configuration information:

[0254] S309: The target network device determines resources for data transmission between the terminal device and the target network device according to the first configuration information.

[0255] Exemplarily, the target network device determines the time domain resources for data transmission with the terminal device according to the first configuration information. Here, in the case where the terminal device determines the first configuration information, the network device does not adjust the first configuration information, and determines the resources for data transmission between the terminal device and the network device according to the first configuration information from the terminal device. In the case where the terminal device recommends the first configuration information, the network device may first adjust the first configuration information from the terminal device, and then determine the resources for data transmission between the terminal device and the network device according to the adjusted first configuration information.

[0256] It should be noted that in the transmission path of "the terminal device sends the first configuration information to the target network device", the terminal device may also execute S301 and S302 after executing S306, such as Figure 5 As shown. In this case, the "target cell" in the relevant description of S302 refers to the target cell indicated by the switching command. After executing S306, the terminal device may first execute S307, and then execute S301 and S302; the terminal device may also first execute S301 and S302, and then execute S307; the terminal device may also execute S301 and S307 at the same time, or execute S302 and S307 at the same time, which is not limited to this embodiment of the present application. In addition, S308 may be executed during the execution of S307, that is, the terminal device transmits the first configuration information to the target network device during the random access process. S308 may also be independent of S307, that is, after the terminal device executes S307, it executes S308. This embodiment of the present application is not limited to this.

[0257] The communication method provided in the embodiment of the present application enables the terminal device to timely update the first configuration information when the terminal device determines to switch to the target cell, or the terminal device switches to the target cell, so that the target network device under the second network can obtain the updated first configuration information in time, so that after the terminal device switches to the target cell, during the process of data transmission with the target network device under the second network, the paging message from the network device under the first network can still be received in time, thereby avoiding the problem of "paging message reception failure" caused by failure to update the configuration information in time in the prior art.

[0258] Example 2: The first configuration information is determined by the source network device.

[0259] See also Figure 6 The communication method of the embodiment of the present application includes the following steps:

[0260] S601: The terminal device sends a cell measurement result to the source network device. Correspondingly, the source network device receives the cell measurement result from the terminal device.

[0261] The source network device belongs to the second network. The cell measurement result includes information such as the reference signal reception quality of the source cell, the reference signal reception quality of the neighboring cell, and the timing deviation information between the cells. Here, the cell measurement result can be carried in the measurement report. The "timing deviation information between the cells" includes at least one of the following three items:

[0262] First, the downlink timing deviation information between the source cell and each neighboring cell.

[0263] Second, downlink timing deviation information between the cell where the terminal device resides in the first network and each neighboring cell.

[0264] Third, downlink timing deviation information between the first cell reselected by the terminal device in the first network and each neighboring cell.

[0265] It is understandable that the neighboring cells in the measurement report include potential target cells. Therefore, the "timing deviation information between cells" may also include at least one of the following three items:

[0266] First, downlink timing deviation information between the source cell and each potential target cell.

[0267] Second, downlink timing deviation information between the cell where the terminal device resides in the first network and each potential target cell.

[0268] Third, downlink timing deviation information between the first cell reselected by the terminal device in the first network and each potential target cell.

[0269] The source network device determines the target cell to which the terminal device is to switch, the target network device corresponding to the target cell, and the first timing deviation information based on the measurement report. Here, if the terminal device does not perform cell reselection in the first network before executing S601, the first timing deviation information includes the downlink timing deviation between the source cell and the target cell, or the downlink timing deviation between the cell where the terminal device resides in the first network and the target cell. If the terminal device performs cell reselection in the first network before executing S601, the first timing deviation information includes the downlink timing deviation between the first cell and the target cell.

[0270] S602: The source network device determines first configuration information according to the first timing deviation information.

[0271] The first configuration information includes GAP configuration information or TDM mode configuration information used by the terminal device after switching to the target cell.

[0272] Here, in the case where the terminal device determines the first timing deviation information, the source network device does not adjust the first timing deviation information, and determines the first configuration information based on the first timing deviation information from the terminal device. In the case where the terminal device recommends the first timing deviation information, the source network device may first adjust the first timing deviation information from the terminal device, and then determine the first configuration information based on the adjusted first timing deviation information.

[0273] If the terminal device does not reselect a cell in the first network, the source network device determines the first configuration information based on the downlink timing deviation between the source cell and the target cell, or the downlink timing deviation between the cell where the terminal device resides in the first network and the target cell. If the terminal device reselects the first cell in the first network, the source network device determines the first configuration information based on the downlink timing deviation between the first cell reselected by the terminal device in the first network and the target cell.

[0274] Optionally, the source network device may also determine the first configuration information in combination with the second configuration information during the process of determining the first configuration information. The introduction of the second configuration information may refer to the relevant description of method 4 in S302, and the specific process of determining the first configuration information in combination with the second configuration information may refer to the relevant description of method 4, method 5, method 9 or method 10 in S302, which will not be repeated here.

[0275] S603: The source network device sends a switching request message to the target network device. Correspondingly, the target network device receives the switching request message from the source network device.

[0276] The switching request message is used to request to switch the terminal device to the target network device. Here, the switching request message also includes first configuration information. After the target network device obtains the first configuration information, it executes S607 based on the first configuration information.

[0277] S604: The target network device sends a switching confirmation message to the source network device. Correspondingly, the source network device receives the switching confirmation message from the target network device.

[0278] The switching confirmation message is used to confirm switching the terminal device to the target network device.

[0279] S605: The source network device sends a switching command to the terminal device. Correspondingly, the terminal device receives the switching command from the network device.

[0280] The handover command includes indication information and first configuration information. The indication information is used to indicate the target cell to be handed over by the terminal device. The first configuration information is used by the terminal device to determine the resources used for data transmission with the target network device.

[0281] S606: In response to the switching command, the terminal device and the target network device perform a random access process.

[0282] The specific implementation process of the random access process can be referred to in the prior art and will not be described in detail here.

[0283] S607: The target network device determines resources for data transmission between the terminal device and the network device according to the first configuration information.

[0284] The specific implementation process of S607 can refer to the relevant description of S309, which will not be repeated here.

[0285] The communication method provided in the embodiment of the present application is that, when the terminal device determines to be switched to the target cell, or the terminal device switches to the target cell, the source network device under the second network promptly obtains the updated first timing deviation information, and then determines the new first configuration information, and transmits it to the target network device, so that after the terminal device switches to the target cell, during the process of data transmission with the target network device under the second network, it can still promptly receive the paging message from the network device under the first network, thereby avoiding the problem of "paging message reception failure" caused by the failure to update the configuration information in time in the prior art.

[0286] Example 3: The first configuration information is determined by the target network device.

[0287] See also Figure 7 or Figure 8 The communication method of the embodiment of the present application includes the following steps:

[0288] S701: The terminal device sends a cell measurement result to the source network device. Correspondingly, the source network device receives the cell measurement result from the terminal device.

[0289] The specific implementation process of S701 can refer to the relevant description of S601, which will not be repeated here.

[0290] As a first possible implementation, see Figure 7 In the case where the measurement report includes "timing deviation information between cells", the source network device transmits the determined first timing deviation information to the target network device, so that the target network device can determine the first configuration information. That is, the source network device executes S702:

[0291] S702: The source network device sends a switching request message to the target network device. Correspondingly, the target network device receives the switching request message from the source network device.

[0292] The handover request message is used to request that the terminal device be handed over to the target network device. Here, if the measurement report includes "timing deviation information between cells", the first timing deviation information is carried in the handover request message to be transmitted from the source network device to the target network device. In addition, if the measurement report does not include "timing deviation information between cells", the handover request message does not include the first timing deviation information.

[0293] Optionally, the switching request message also includes second configuration information, and the second configuration information is used by the target network device to determine the first configuration information.

[0294] S703: The target network device determines first configuration information according to the first timing deviation information.

[0295] The specific implementation process of S703 can refer to the relevant description of S602, which will not be repeated here.

[0296] S704: The target network device sends a switching confirmation message to the source network device. Correspondingly, the source network device receives the switching confirmation message from the target network device.

[0297] The switching confirmation message is used to confirm the switching of the terminal device to the target network device. When the target network device executes S703, the switching confirmation message further includes the first configuration information.

[0298] S705: The source network device sends a switching command to the terminal device. Correspondingly, the terminal device receives the switching command from the network device.

[0299] The handover command includes indication information. The indication information is used to indicate the target cell to be switched by the terminal device. In the case where the handover confirmation message includes the first configuration information, the handover command also includes the first configuration information. The first configuration information is used by the terminal device to determine the resources used for data transmission with the target network device.

[0300] S706: In response to the switching command, the terminal device and the target network device perform a random access process.

[0301] The specific implementation process of the random access process can refer to the prior art, which will not be described in detail here. After the random access process between the terminal device and the target network device is completed, the target network device executes S710.

[0302] As a second possible implementation, see Figure 8 In the case where the measurement report does not include “timing deviation information between cells”, the handover command does not include the first configuration information, and the terminal device executes S707:

[0303] S707: The terminal device determines a first event.

[0304] The specific implementation process of S707 can refer to the relevant description of S301, which will not be repeated here.

[0305] S708. The terminal device determines first timing deviation information.

[0306] Among them, the first timing deviation information includes the downlink timing deviation between the source cell and the target cell, or the downlink timing deviation between the cell where the terminal device resides in the first network and the target cell, or the downlink timing deviation between the first cell reselected by the terminal device in the first network and the target cell.

[0307] Here, if the terminal device does not reselect a cell in the first network, the first timing deviation information includes a downlink timing deviation between the source cell and the target cell, or a downlink timing deviation between the cell where the terminal device resides in the first network and the target cell. If the terminal device reselects to the first cell in the first network, the first timing deviation information includes a downlink timing deviation between the first cell reselected by the terminal device in the first network and the target cell.

[0308] "The terminal device determines the first timing deviation information" may mean: after the target network device obtains the first timing deviation information, the target network device can use the first timing deviation information to obtain the resources used for data transmission with the terminal device, and the target network device does not correct the first timing deviation information. Alternatively, "the terminal device determines the first timing deviation information" may also mean: after the terminal device recommends the first timing deviation information to the target network device under the second network, the target network device uses the first timing deviation information as auxiliary information or reference information, and may first correct the first timing deviation information, and obtain the resources used for data transmission with the terminal device according to the corrected first timing deviation information.

[0309] There are many ways for the terminal device to determine the first timing deviation information, such as but not limited to the following three ways:

[0310] Method 1: The terminal device determines the first timing deviation information according to the downlink timing of the source cell and the downlink timing of the target cell.

[0311] Method 2: The terminal device determines the first timing deviation information according to the downlink timing of the cell where the terminal device resides in the first network and the downlink timing of the target cell.

[0312] Method three: The terminal device determines the first timing deviation information according to the downlink timing of the first cell and the downlink timing of the target cell.

[0313] Optionally, when a certain condition is met, the terminal device determines the first timing deviation information. Here, the condition for the terminal device to determine the first timing deviation information is recorded as "condition 5", and condition 5 includes at least one of the following:

[0314] First, the downlink timing of the source cell is different from the downlink timing of the target cell.

[0315] Second, the network equipment to which the source cell belongs is different from the network equipment to which the target cell belongs.

[0316] Third, the downlink timing of the first cell is different from the downlink timing of the target cell.

[0317] Fourth, the network equipment to which the first cell belongs is different from the network equipment to which the target cell belongs.

[0318] In this way, the terminal device determines the first timing deviation information only when at least one of condition 5 is met, so as to avoid the terminal device frequently updating the first timing deviation information. It also avoids the terminal device frequently sending the first timing deviation information to the target network device under the second network, thereby saving air interface resources.

[0319] Optionally, after the terminal device determines the first timing deviation information, the terminal device determines the first configuration information according to the first timing deviation information. For example, the terminal device adjusts the second configuration information according to the first timing deviation information to obtain the first configuration information.

[0320] In this way, the terminal device can obtain the first configuration information based on the first timing deviation information, so that after switching to the target cell, the terminal device can use the first configuration information to transmit data with the target network device, and enable the terminal device to receive the paging message of the network device under the first network in time to improve the success rate of paging message reception.

[0321] S709: The terminal device sends the first timing deviation information to the target network device. Correspondingly, the target network device receives the first timing deviation information from the terminal device.

[0322] Optionally, after the target network device confirms receipt of the first configuration information, the target network device sends a first confirmation message to the terminal device. Accordingly, the terminal device receives the first confirmation message from the target network device. The first confirmation message is used to indicate that the target network device has received the first timing deviation information. After the target network device receives the first timing deviation information from the terminal device, the target network device first executes S703 and then executes S710.

[0323] S710. The target network device determines resources for data transmission between the terminal device and the target network device according to the first configuration information.

[0324] The specific implementation process of S710 can refer to the relevant description of S309, which will not be repeated here.

[0325] It should be noted that, in the embodiment of the present application, after executing S705, the terminal device may first execute S706, and then execute S707 and S708; the terminal device may also first execute S707 and S708, and then execute S706; the terminal device may also execute S706 and S707 at the same time, or execute S706 and S708 at the same time, which is not limited in the embodiment of the present application. In addition, S709 may be a step in the random access process, that is, S709 is executed during the execution of S706. S709 may also be two steps independent of S706, which is not limited in the embodiment of the present application.

[0326] The communication method provided in the embodiment of the present application enables the terminal device to timely update the first timing deviation information when the terminal device determines to switch to the target cell, or the terminal device switches to the target cell, so that the target network device under the second network can obtain the updated first timing deviation information in time, thereby determining the first configuration information, so that after the terminal device switches to the target cell, during the process of data transmission with the target network device under the second network, the paging message from the network device under the first network can still be received in time, thereby avoiding the problem of "paging message reception failure" caused by failure to update the configuration information in time in the prior art.

[0327] The above mainly introduces the scheme provided by the embodiment of the present application from the perspective of interaction between various network elements. Accordingly, the embodiment of the present application also provides a communication device, which can be a network element in the above method embodiment, or a device including the above network element, or a component that can be used for a network element.

Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of this application.

Optionally, the storage unit is a storage unit in the chip, such as a register, a cache, etc., and the storage unit can also be a storage unit in the terminal device that is located outside the chip, such as a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM), etc.
