In the following method embodiments, for convenience of description, only the main execution body of each step is described as a terminal.

The following describes in detail a control method of an antenna switch template according to an embodiment of the present application with reference to fig. 2 to 5.

Referring to fig. 2, a flowchart of a method for controlling an antenna switch template is provided in an embodiment of the present application. The control method of the antenna switch template comprises the following steps:

s201, when the fact that the serving cell meets the cell switching condition is detected, a target cell is determined.

Generally, a serving cell in which the terminal device resides is a TDD cell, and the terminal device can identify the serving cell as the TDD cell or the FDD cell through a frequency band of the serving cell. Cell handover refers to the need for a different cell channel handover in order to maintain uninterrupted communication for the user of the terminal device when the terminal device moves from one serving cell to a target cell in a wireless communication system. The cell switching condition refers to a rule for whether the terminal device needs to execute cell switching, and there are three main rules: rule 1, determining from the received signal carrier level of the serving cell; rule 2, determining according to the carrier-to-interference ratio of the signal received by the serving cell; rule 3 is determined according to the distance from the terminal device to the network device. When the rule 1 is used for judging, if the signal carrier level is lower than the threshold level (for example, -100dBm), the cell switching condition is determined to be met; when the rule 2 is used for judging, if the carrier to interference ratio is lower than a given value, determining that the cell switching condition is met; when the judgment is made by using rule 3, if the distance is greater than a given value, it is determined that the cell switching condition is satisfied.

Among them, the handover can be classified into a hard handover and a soft handover. The hard handover is a process of releasing-connecting, in which the terminal equipment firstly releases the service connection with the serving cell and then establishes connection with the target cell; soft handover refers to that a terminal device will establish service connections with two or more cells simultaneously, and then compare the quality of the connections, select a best cell to continue to maintain the connection, and release the rest of the cells, which is a "setup-comparison-release" process, where the serving cell and the target cell can coexist for a period of time. In a Code Division Multiple Access (CDMA) system, a cell handover may be a soft handover or a hard handover. In Frequency Division Multiple Access (FDMA) and Time Division Multiple Access (TDMA), all handoffs are hard handoffs. LTE is a frequency division multiple access system, and therefore LTE handover is also a hard handover, where the connection with the TDD cell of the serving cell is released first, and then the connection with the FDD cell of the target cell is established.

S202, when the target cell is an FDD cell in a frequency division duplex mode, resetting the ASM in the cell switching process.

Generally, the ASM is used for performing operations such as transmitting and receiving signals of the terminal equipment and performing switching between frequency bands under software support control. The terminal equipments for communication have ASM, and some are also called combiner or duplex filter. An ASM generally includes a switch, a decoder, a Power Amplifier (PA), a low pass filter, an Electrostatic Discharge (ESD) circuit, and a voltage generator. The reset operation is to set the ASM to an initial state, and generally, a modem control part of the terminal device sends a reset level signal, and the ASM controls the interface channel after receiving the signal.

As can be seen from the above, when the serving cell where the terminal device is located is a TDD cell, the serving cell is determined to satisfy the handover condition by detecting and judging that the serving cell satisfies the handover condition, the target cell is determined to be an FDD cell, cell handover operation configuration is performed, and a reset operation is performed on the ASM in the handover process. The terminal equipment needs to configure the ASM when being connected with the TDD cell, and does not need to configure the ASM when being connected with the FDD cell, and the ASM working states are different when being connected with different cells. When the terminal equipment connection network is switched from the TDD cell to the FDD cell, because the ASM keeps the working state when being connected with the TDD cell, the ASM is in the abnormal working state to influence the normal connection of the terminal equipment with the FDD cell, thereby causing the problem of disconnection. Therefore, the scheme solves the problem of disconnection when the terminal equipment is switched from the TDD cell to the FDD cell by executing the reset operation on the ASM, and improves the network connection quality.

Referring to fig. 3, another flow chart of a method for controlling an antenna switch template is provided in an embodiment of the present application. The control method of the antenna switch template can comprise the following steps:

s301, receiving a measurement configuration message from the network equipment.

Generally, a terminal device receives a configuration message issued by a network device, and configuration parameters in the configuration message include one or more of a measurement object, a cell list, a reporting mode, a measurement identifier, and an event parameter. The measurement object may be an intra-frequency cell or an inter-frequency cell, for example: the measurement object comprises LTE common frequency or different frequency information, a group of common frequency cells of universal terrestrial radio UTRA, a group of frequencies of GSM/EDGE (second generation mobile network) wireless communication network GERAN and a group of common frequency cells of CDMA2000 (third generation mobile communication standard). The measurement identity represents an identity of a measurement task performed by the terminal device, and may be represented by a list of measurement ids (measurement ids). The Measurement Gap (Measurement Gap) is a time interval in which the terminal device executes a Measurement task, and the terminal device does not perform uplink and downlink scheduling communication in the time interval. When the terminal equipment executes the same-frequency measurement, the measurement and the data transmission do not conflict; when performing the RAT measurement of the inter-frequency system, if the terminal device does not have multiple receiving apparatuses, it is unable to perform data transmission on the serving cell at the same time, and in order to perform handover configuration for the terminal device, the terminal device needs to configure a measurement gap for measurement, where the current measurement gap has two modes, for example: one measurement gap interval is 40ms and the other measurement gap interval is 80 ms.

S302, the serving cell is measured based on the measurement configuration message.

Generally, a terminal device parses a measurement configuration message to determine data parameters of a network device that the terminal device needs to obtain. The measurement result, if belonging to the same frequency measurement, includes Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and path loss (Pathloss); if the pilot frequency measurement is carried out, the RSRP, the RSRQ and the Pathloss are included; if the measurement belongs to the inter-system measurement, the Code Power (RSCP) of a Primary Common Control Physical Channel (PCCPCH) receiving Signal, the Code Power (RSCP) Received by a Common Pilot Channel (CPICH), the value (CPICH Ec/No) of Received energy per chip divided by Power density in a band, a Received Signal strength indication (gsm _ CarrierRSSI), a base station Identification Code (BSIC Identification) and a base station reconfiguration Code (BSIC reconfiguration) are included.

And S303, judging whether the RSRP is smaller than the coverage intensity level.

Generally, after the terminal device measures the serving cell, a measurement result including RSRP is obtained, and it is further necessary to determine whether the RSRP is smaller than the coverage strength level. And if the RSRP is smaller than the preset coverage intensity level of the terminal equipment, the requirement of the coverage intensity level of the target cell is met. For example: the RSRP value measured by the terminal equipment is-60 dBm, the preset coverage intensity threshold level of the terminal equipment is 4-60 dBm, and the RSRP value belongs to the coverage intensity level 2, so that the RSRP measured by the terminal equipment is smaller than the coverage intensity level of the preset target cell, and the judgment condition is met. And after the terminal equipment judges that the measurement result is finished, reporting the measurement result, and before reporting, judging whether the reporting condition is met. The terminal equipment compares the size of the inequality decision parameter with the preset Reporting condition by measuring the obtained measurement event report parameter, including a relative Threshold (Reporting Range), an absolute Threshold (Threshold), a Hysteresis Threshold (hysteris), a delay trigger Time (Time to trigger) and an Offset (Offset).

S304, receiving a switching message from the network equipment.

Generally, the terminal device receives a handover message sent by the network device, and may determine whether to perform handover based on the handover command message RRC Connection Reconfiguration.

And S305, finishing the switching process.

Generally, if the coverage intensity level to which the RSRP value measured by the terminal device belongs is greater than a preset coverage intensity level threshold, the handover measurement process is ended, and the terminal device does not perform cell handover operation.

S306, analyzing the switching message to determine the target cell.

Generally, the terminal device parses the handover message RRCConnectionReconfiguration, and determines whether the handover message includes a mobility control information element. If so, the terminal device sends an instruction according to the basic configuration included in the message, for example: if the timer T310 in the terminal equipment is running, controlling a stopping instruction; an instruction of the timer T304 is started. The terminal equipment also analyzes and judges whether the switching message contains a field carrierFreq, if so, the target Cell is considered to be positioned on the frequency specified by the carrierFreq, and the target Cell can be determined by Physical Cell Identifier (PCI) established by the field targetPhysCellId; if not, the terminal device considers that the target cell is on the current frequency, and may determine the target cell by the PCI specified by the cell targetCellIdentity in the handover message.

S307, acquiring the frequency of the target cell.

Generally, the terminal device further includes a signaling message frequency band indicator cell obtained by measuring the serving cell according to the measurement configuration message, and can determine a frequency band indication to which a target cell frequency band belongs according to the cell. For example: the parameter indicated by the target cell frequency Band measured by the terminal device is configured as Band40, and then the corresponding target cell frequency range can be known to be 2300-2400MHz according to the specification.

S308, judging whether the frequency band of the target cell is positioned in a preset frequency band of the FDD cell.

Generally, according to different frequency bands of different cells, the terminal device may determine the cell type according to the frequency band value. For example: the terminal equipment acquires that the frequency range of the target cell is 2300 plus 2320MHz, and judges that the target cell is a TDD cell if the frequency belongs to the frequency band of the China Unicom TDD cell according to the regulation; the terminal equipment acquires that the frequency range of the target cell is 1755-1785MHz, and judges that the target cell is an FDD cell according to the fact that the frequency belongs to the frequency band of the FDD cell of the Chinese telecommunication; the terminal equipment acquires that the frequency range of the target cell is 2145-2170MHz, and judges that the target cell is an FDD cell if the frequency belongs to the frequency band of the China Unicom FDD cell according to the stipulation; if the terminal device detects a plurality of FDD target cells, the terminal device determines an FDD cell with the smallest coverage intensity level.

S309, resetting the ASM in the process of executing cell switching.

Generally, after the terminal device determines that the target cell is an FDD cell, the terminal device sends an ASM reset level signal to perform a reset operation. The terminal equipment executes switching control on the working state of the ASM through the reset level signal, and the ASM opens or closes the corresponding channel under the control of the reset level signal. The embodiment of the application is characterized in that the terminal equipment is switched from a TDD cell to an FDD cell, because the TDD cell is connected before the terminal equipment is switched, the terminal equipment needs to execute ASM configuration, and after the terminal equipment is switched to the FDD cell, the ASM configuration does not need to be executed, but the ASM keeps the current working state, and the cell switching can be disconnected when the ASM is in an abnormal working state.

And S310, indicating the ASM to keep the current working state.

Generally, when the terminal device determines that the target cell is not an FDD cell, the terminal device does not perform cell switching and ASM reset operations, and maintains the current TDD cell operating state.

When the scheme of the embodiment of the application is executed, the terminal device determines that the current serving cell is a TDD cell, and determines whether the measurement reporting condition is met by receiving a measurement control message issued by the network device. And if the condition is met, reporting the measurement report periodically. And after receiving the measurement report, the network equipment makes a measurement judgment and sends a measurement result to the terminal equipment. And after receiving the measurement result, the terminal equipment analyzes the switching message in the measurement result, judges whether the message contains a mobile switching information element, judges whether the target cell is an FDD cell if the message contains the mobile switching information element, and sends a reset level signal and executes ASM reset operation if the target cell is the FDD cell. If not, the terminal equipment keeps the current cell working state. In the embodiment of the application, the terminal device can solve the problem of dropped connection caused by switching from the TDD cell to the FDD cell by executing the reset operation.
