Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
Example one
To solve the above technical problems in the prior art, embodiments of the present invention provide a method for implementing coexistence of WWAN and WLAN.
Fig. 1 is a flowchart of an embodiment of a method for implementing WWAN and WLAN coexistence according to the present invention, and as shown in fig. 1, the method for implementing WWAN and WLAN coexistence according to the present embodiment may specifically include the following steps:
100. if the request of using the WLAN is monitored, acquiring the operation information of the WWAN;
in practical applications, the request for using the WLAN includes a request for turning on the WLAN or a request for accessing the internet through the WLAN, for example, a user touches a control switch corresponding to the WLAN, and the request for turning on the WLAN can be monitored. When the WLAN is always on, the user enters an environment with the WLAN from an environment without the WLAN, and may monitor a request for accessing the internet through the WLAN.
In this embodiment, a communication connection may be established between the WLAN chip and the WWAN chip, for example, the communication between the WLAN chip and the WWAN chip may be established in communication manners such as I2C, UART, SPI, and the like. If a request for using the WLAN is monitored, the operation information of the WWAN corresponding to the WWAN chip can be acquired through the WLAN chip. For example, the operating information of the WWAN may include an operating frequency band of the WWAN and/or an operating frequency point of the WWAN.
101. Judging whether the operation information of the WWAN interferes with the WLAN mutually according to preset coexistence interference information between the WWAN and the WLAN;
in this embodiment, an interference test of an operating frequency band and/or an operating frequency point may be performed on the WWAN and the WLAN, so that coexistence interference information between the WWAN and the WLAN may be obtained through the experimental data, and the coexistence interference information between the WWAN and the WLAN may be stored in advance. Therefore, after the operation information of the WWAN is obtained, the operation information of the WWAN can be compared with preset coexistence interference information between the WWAN and the WLAN to determine whether the operation information of the WWAN interferes with the WLAN. For example, if the operation information of the WWAN exists in the preset coexistence interference information between the WWAN and the WLAN (that is, the coexistence interference frequency band and/or frequency point between the WWAN and the WLAN includes the operation frequency band of the WWAN and/or the operation frequency point of the WWAN), it may be determined that the operation information of the WWAN and the WLAN has coexistence interference, otherwise, the operation information of the WWAN does not exist in the preset coexistence interference information between the WWAN and the WLAN (that is, the coexistence interference frequency band and/or frequency point between the WWAN and the WLAN does not include the operation frequency band of the WWAN and/or the operation frequency point of the WWAN), and it may be determined that the operation information of the WWAN does not have coexistence interference with the WLAN, and then the WLAN operation is directly controlled.
102. If the running information of the WWAN and the WLAN have mutual interference, triggering a WWAN switching condition and controlling the WWAN to switch to target running information which does not have mutual interference with the WLAN;
if the operation information of the WWAN and the WLAN have mutual storage interference, the initial measurement signal strength reported by the WWAN can be acquired; and triggering the WWAN switching condition according to the initial measured signal strength and a preset signal offset. The initial measured signal strength reported by the WWAN is the signal strength corresponding to the operating information of the WWAN, which is periodically and/or non-periodically measured by the WWAN. The initial measured Signal Strength may be a Received Signal Strength (RSSI), a Reference Signal Receiving Power (RSRP), or the like, such as RSSI for 2G Signal Strength, RSRP for 3G &4G &5G Signal Strength. The preset signal offset is a negative value.
In practical application, the initial measured signal strength is offset adjusted at least once by using a preset signal offset until the obtained offset signal strength of the WWAN is smaller than the current serving cell quality threshold, and a WWAN handover condition is triggered. For example, if the initial measured signal strength of the measured RSSI is-85, the reported offset signal strength of the WWAN after adding the offset is (-85+ X), at this time, if (-85+ X) is smaller than the current serving cell quality threshold a, the offset is stopped, otherwise, the offset is continued after adjusting X by taking Y as a step (Y may be 1, 2, 3, 4, 5 …), until the obtained offset signal strength of the WWAN is smaller than the current serving cell quality threshold, the WWAN handover condition may be triggered.
After the WWAN handover condition is triggered, the WWAN handover may be controlled to target operational information that does not interfere with the WLAN.
In particular, a Radio Resource Control (RRC) reconfiguration instruction may be received; wherein the RRC reconfiguration command includes a reconfiguration serving cell quality threshold and WWAN switchable operation information. After the RRC reconfiguration command, the WWAN can be controlled to report switchable operation information meeting the reporting condition to the base station according to the quality threshold of the reconfigured serving cell and the coexistence interference information; receiving target operation information which is sent by a base station and does not interfere with the WLAN; and controlling the WWAN to switch to the target operation information without mutual interference with the WLAN. The reporting condition in this embodiment may include: the measured signal strength corresponding to the switchable operation information of the WWAN is greater than or equal to the reconfiguration serving cell quality threshold, and the switchable operation information of the WWAN is not matched with the coexisting interference information.
In practical applications, the RRC reconfiguration command may further include a measurement value (RSRP, RSRQ …), a measurement period, and the like; the serving cell quality threshold and the WWAN switchable operation information may be represented by measureID, where measureID is a combination of measurobj + MeasureReport, measureobject id is a measurement object indicator, such as which frequency band channel number to test, and MeasureReport is a measurement report identifier, corresponds to a measurement report configuration item, and includes a common configuration item unrelated to measureoid, a measurement configuration, a serving cell quality threshold, and the like; simply, the base station tells the terminal to measure a certain ID (for example, a certain channel of a certain frequency band), and tells the terminal the required conditions configured by the base station (quality control threshold of a service cell, etc.), the terminal measures according to the conditions issued by the base station, and reports the ID meeting the conditions to the base station; the terminal enters actual measurement after receiving measurement control issued by the base station, and reports a measurement report measure report to the base station, and in the measurement reporting process, filters a measure ID (the measurement signal strength corresponding to the switchable operation information of the WWAN is greater than or equal to the quality threshold value of the reconfigured serving cell) meeting the switching requirement, and filters out frequency bands and frequency points with coexistence interference preset in parameters by the terminal (the switchable operation information of the WWAN is matched with the coexistence interference information), wherein the filtering is that even if the reporting condition is met, the filtering is not fed back to the base station (the base station does not report the ID to the base station, and the base station determines that the ID does not meet the configuration condition requirement).
103. And if the WWAN is monitored to complete the switching, controlling the WLAN to operate.
In a specific implementation process, a period of time is reserved before the WLAN enters the operating state, and if it is monitored that the WWAN completes handover, the WLAN is controlled to operate, so that the WLAN and the WWAN can operate in operating frequency bands and/or operating frequency points with large differences, thereby preventing the WLAN from entering the operating state and causing the WWAN and/or WLAN operation to be affected, such as direct call drop, poor call quality, slow internet access and the like, when the WLAN and the WWAN are close to each other.
In the method for implementing coexistence of WWAN and WLAN in this embodiment, if a request for using WLAN is monitored, operation information of WWAN is obtained, and when the operation information of WWAN and the WLAN interfere with each other according to preset coexistence interference information between WWAN and WLAN, WWAN handover conditions are triggered and WWAN handover is controlled to target operation information that does not interfere with WLAN with each other; if the WWAN is monitored to complete the switching, the WLAN operation is controlled, the WLAN and the WWAN work in operation frequency bands and/or operation frequency points with larger differences, and the phenomena that the receiving quality of the other party is reduced due to the fact that the respective transmission frequency spectrum stray falls into the receiving frequency band of the other party, the error rate is improved, and the throughput is reduced are avoided, so that the conditions that the WWAN and the WLAN coexist have a faster network and better conversation quality are guaranteed.
In one specific implementation, since there may not be a WLAN around the user, at this time, although the WLAN is always in the on state, no traffic request is generated, coexistence interference between the WLAN and the WWAN does not exist, and the operating information of the WWAN cannot be switched because the WLAN is on, it may be: when detecting that the WIFI is not used for a long time and enters a deep sleep state, the WWAN can switch to the measurement reporting process and turn off the coexisting interference frequency point filtering function, so that the WWAN can work under the best operation information.
It should be noted that the method of the embodiment of the present invention may be executed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene and completed by the mutual cooperation of a plurality of devices. In the case of such a distributed scenario, one device of the multiple devices may only perform one or more steps of the method according to the embodiment of the present invention, and the multiple devices interact with each other to complete the method.
