Detailed Description
In practical application, the bandwidth corresponding to the eMTC UE is 1.4MHz, and data is transmitted and received in resources of 6 Physical Resource Blocks (PRBs) at most in the same subframe. The bandwidth corresponding to the NB-IoT UE is 180KHz, and data is received and sent in resources of at most one PRB in the same subframe. The NB-IoT supports transmission of low traffic data at rates below 100Kbps, while the eMTC supports the highest data transmission rate of up to 1 Mbps. The eMTC is inferior to NB-IoT in signal coverage depth (the wall penetrating capability of the eMTC is improved by 15dB compared with that of Cat.4LTE, and the wall penetrating capability of the NB-IoT is improved by 20dB compared with that of Cat.4LTE), power consumption and cost. However, eMTC has the advantages: faster transmission rate, lower latency (on the order of 100ms, NB-IoT on the order of seconds), mobility supported, Frequency Division Duplex (FDD), positioning, voice over lte supported, etc.
The eMTC and NB-IoT technology can realize network coverage in an elevator or a basement without other network coverage such as LTE and the like by methods such as repeated transmission, narrow-band low-speed and the like. In addition, through methods such as a Power Saving Mode (PSM), discontinuous reception, narrowband low speed, simplified signaling flow and the like, the UE supporting eMTC and NB-IoT can also obtain benefits in low power consumption. For example, NB-IoT capable UEs have their standby time measured annually when the battery is fully charged. In addition, the terminal supporting the eMTC and NB-IoT modes is also suitable for enhanced Discontinuous reception (eDRX), the paging cycle of eDRX can reach 40 minutes at most, and compared with paging cycle configurations such as 1.28 seconds or 2.56 seconds, the power consumption of the UE suitable for eDRX is significantly lower.
When a disaster such as an earthquake occurs, the terminal user may be limited to the underground and cannot get out of the ground, and at this time, the reduction of power consumption of the UE and the smoothness of signals become important, especially when the terminal is low in power. Therefore, compared with other network modes, the coverage enhancement and the ultra-low power consumption of the NB-IoT or eMTC are more suitable for the requirements in certain disaster situations.
However, in the current communication protocol, LTE, eMTC, and NB-IoT are considered to belong to one network mode, so that the existing multimode terminal generally involves switching between a 2G or 3G network mode and an LTE mode when performing network mode switching, so that the existing multimode terminal cannot benefit from both the low power consumption and wide coverage characteristics of NB-IoT or eMTC and the high data rate and low latency characteristics of other networks, and the user experience is poor.
In view of the foregoing problems, an embodiment of the present invention provides a network mode switching method, where when performing network mode switching on a UE, switching between network modes includes: the NB-IoT mode and other network modes are switched, or the eMTC mode and other network modes are switched, so that the multimode terminal can benefit from the characteristics of low power consumption and wide coverage of the NB-IoT or the eMTC and the characteristics of high data rate and low time delay of other networks, and the user experience is improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a network mode switching method, where the method may include the following steps:
and step 11, detecting the current network state information and the current state information of the UE.
In a specific implementation, the current network status information may include a variety of information, and is not limited in particular.
For example, the current network state information may include: the UE can camp on a network of other network modes than the NB-IoT mode and the eMTC mode, and the UE can receive wireless signals of the network of other network modes than the NB-IoT mode and the eMTC mode. When the network where the UE currently resides is a network in other network modes except the NB-IoT mode and the eMTC mode, a service condition provided by the network where the UE currently resides may also be detected.
In the embodiment of the present invention, the network modes other than the NB-IoT mode and the eMTC mode may include: global System for Mobile communications (GSM) 2G, General Packet Radio Service (GPRS), Enhanced Data Rate for GSM Evolution (EDGE), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) or Wideband Code Division Multiple Access (W-CDMA) 3G, Long Term Evolution (LTE) 4G, and 5G, etc. Here, LTE is a mode other than NB-IoT and eMTC.
In a specific implementation, the current state information of the UE may also include multiple types, which is not limited specifically.
For example, the current state information of the UE may include current battery power information of the UE, and operation instruction information such as a power saving mode and an airplane mode received by the UE.
And step 12, judging whether the corresponding network mode switching condition is met or not based on the detection result.
Wherein switching between the network modes comprises: switching of NB-IoT mode with other network modes, or switching of eMTC mode with other network modes.
In a specific implementation, after the detection result is obtained, whether the corresponding network mode switching condition is met or not can be judged based on the network where the UE currently resides, so as to perform network mode switching on the UE. It can be understood that for switching between different network modes, different network mode switching conditions can be set to provide better network service for the UE.
Since LTE, eMTC and NB-IoT are considered to belong to one network mode in the current communication protocol, when the UE is switched between network modes, the involved network mode does not include the eMTC or NB-IoT mode. However, in the actual communication process, defined in 3GPP TS 36.306, the terminal class corresponding to NB-IoT UE is M2, the terminal class corresponding to eMTC UE is M1, and the terminal class corresponding to LTE UE is numbered from 1, for example, downlink class number is 19, and uplink class number is 21, although the sequence numbers are not completely consecutive. In the LTE specifications of the low release, the terminal classes corresponding to LTE UEs are not separately numbered in uplink and downlink, but are numbered consecutively from 1 to 12. Because the eMTC UE, the NB-IoT UE and the LTE UE correspond to different terminal categories, the eMTC, the NB-IoT and the LTE are taken as different network modes of the UE in the embodiment of the invention. Therefore, in the embodiment of the present invention, when the network mode of the UE is switched, the involved network mode may include at least one of eMTC and NB-IoT.
Compared with other network modes, the time delay of the UE in the NB-IoT and eMTC modes is large, the service requirements of medium and high data rates cannot be met, the network coverage dead angle is less, the power consumption is lower, and the requirements under certain disaster conditions are better met, so that the UE can benefit from the characteristics of low power consumption and wide coverage of the NB-IoT or eMTC and the characteristics of high data rate and low time delay of other networks, and the user experience is improved.
And step 13, when the corresponding network mode switching condition is met, switching the network mode of the UE, and enabling the UE to reside in the network of the switched network mode.
In an embodiment of the present invention, when the UE resides in a network mode other than NB-IoT mode or eMTC mode and a first switching condition is satisfied, the network mode of the UE is switched to NB-IoT mode or eMTC mode. Specifically, the switching to the NB-IoT mode or the eMTC mode may be selected by the UE according to factors such as an actual network state, or may be determined based on the configuration of the base station, which is not limited specifically. It is understood that, when the first switching condition is satisfied, whether switching to the NB-IoT mode or the eMTC mode does not constitute a limitation to the present invention, and is within the scope of the present invention.
In a specific implementation, the first switching condition may be set according to actual needs. In an embodiment of the present invention, the first switching condition may include at least one of:
wireless signals of other network modes except the NB-IoT mode and the eMTC mode cannot be detected within a first preset time length;
the UE cannot reside in a network of other network modes except for an NB-IoT mode and an eMTC mode;
the UE currently resides in a network of other network modes except an NB-IoT mode and an eMTC mode, and the resident network can only provide emergency call service;
the current state information of the UE meets a power saving mode entering condition or an airplane mode entering condition.
In a specific implementation, the first preset time period may be set according to an actual situation. For example, the first preset duration may be set to be a timer T310 in LTE, or an integer multiple of T310. The timer T310 is used for determining radio link failure, and the value range is from 0ms to 2000 ms, and usually 1000 ms. However, if it is a scene in which the elevator is not covered, it may take about 1 minute to get in and out of the elevator, and thus the first preset time period may be set to 1 minute or even longer.
When the UE cannot detect the wireless signals of the network modes other than the NB-IoT mode and the eMTC mode within the first preset time period, or the UE cannot reside in the network modes other than the NB-IoT mode and the eMTC mode, or the network where the UE resides can only provide the emergency call service, it is indicated that the current area of the UE is not effectively covered by the wireless signals of the other network modes, for example, the UE may be in a basement or encounter an earthquake disaster, and the like, so by switching the network mode of the UE to the NB-IoT mode or the eMTC mode, the network coverage of the UE can be maintained, and the communication of the UE is kept smooth.
In a specific implementation, the power saving mode entry condition may be set by a variety of methods, and is not limited in particular.
In an embodiment of the present invention, when the remaining battery capacity of the UE is lower than a predetermined capacity value, or the percentage of the remaining battery capacity of the UE is lower than a predetermined percentage, the UE may enter the power saving mode.
In another embodiment of the present invention, a power saving mode selection button may be provided in a menu option of the UE. The terminal user can select the power saving mode selection key by selecting the power saving mode selection key. And when the power saving mode selection key is selected, the UE enters a power saving mode.
In specific implementation, after the UE enters the power saving mode, only the power supplies of the functional modules, circuits and chips used in the NB-IoT mode or the eMTC mode in the UE are reserved, and the power supplies of the functional modules, circuits and chips corresponding to other network modes are cut off, so that the power consumption of the UE is reduced.
In particular implementations, the flight mode entry condition may be set in a variety of ways. For example, the flight mode selection button may be set up in a menu option of the UE. The end user may select the flight mode selection button by selecting it. And when the flight mode selection key is selected, the UE enters a flight mode.
In another embodiment of the present invention, when the UE resides in a network of other network mode than NB-IoT mode and the current traffic of the UE is interrupted due to link failure, the network mode of the UE is switched to NB-IoT mode based on a pre-acquired system message of an NB-IoT cell.
In a specific implementation, the NB-IoT mode only provides Packet Switched (PS) domain traffic, so the current traffic of the UE may be PS domain traffic. When the current service of the UE is interrupted due to a link failure, the network mode of the UE may be switched to the NB-IoT mode based on a system message of the NB-IoT cell acquired in advance.
In particular implementations, the UE may acquire the system message of the NB-IoT cell when the second handover condition is satisfied. Wherein the second switching condition may be set as: and continuously deteriorating the quality of the wireless signal of the network where the UE currently resides within a second preset time.
For example, after the UE enters an area with poor signals, such as an elevator, the UE may detect that the quality of the wireless signal of the network where the UE resides in the second preset time duration is continuously poor, and at this time, in order to enhance the coverage capability of the network, the network mode of the UE may be switched to an NB-IoT mode, so as to keep the communication of the UE smooth.
In specific implementation, the base station may send the system message of the corresponding cell to the UE in advance based on the capability information that the UE supports coverage enhancement, and then the UE may switch the network mode to the NB-IoT mode in time when the current service is interrupted due to link failure, so as to avoid delaying communication.
In another embodiment of the present invention, because the eMTC mode may improve the voice service, when the UE resides in a network in another network mode other than the eMTC mode and the current voice service of the UE is interrupted due to a link failure, the network mode of the UE may be switched to the eMTC mode based on a system message of an eMTC cell acquired in advance, and the UE is controlled to initiate a call immediately.
In specific implementation, the UE may acquire the system message of the eMTC cell when the second handover condition is satisfied, or the base station may send the system message of the eMTC cell to the UE in advance based on the capability information that the UE supports coverage enhancement.
In yet another embodiment of the present invention, when the UE resides in an NB-IoT mode or eMTC mode network and a third switching condition is satisfied, the network mode of the UE is switched to an NB-IoT mode and other network modes other than eMTC.
In a specific implementation, the third switching condition may be any one of:
continuously detecting wireless signals of other network modes except the NB-IoT mode and the eMTC mode within a third preset time length;
the UE may camp on a network of other network modes besides NB-IoT mode and eMTC mode;
the network of the NB-IoT mode and other network modes except the eMTC mode where the UE resides can provide emergency call services and other non-emergency communication services;
the current state information of the UE meets the condition of exiting from the power saving mode or the condition of exiting from the flight mode.
In a specific implementation, the third preset time period may be set according to actual needs. The third preset duration may be equal to the first preset duration, or may be greater than or less than the first preset duration.
In a specific implementation, the non-emergency communication service may include a call service, a download service, and the like, and is not limited specifically.
In particular implementations, the power saving mode exit condition may be set in a variety of ways. For example, the UE may exit the power saving mode when the remaining battery power is higher than a preset power value, or the percentage of the remaining battery power of the UE is higher than a preset percentage. Or when the power saving mode selection key on the UE is not selected, the UE exits the power saving mode.
