Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that the terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present invention are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
The terminal device in the embodiment of the present invention may be referred to as a User Equipment (UE). The terminal device may be a personal communication service (personal communication service, PCS) phone, cordless phone, session initiation protocol (session initiation protocol, SIP) phone, wireless local loop (wireless local loop, WLL) station, personal digital assistant (personal digital assistant, PDA) or the like, or a handset, mobile Station (MS), mobile terminal (mobile terminal), laptop or the like, which may communicate with one or more core networks via a radio access network (radio access network, RAN). For example, the terminal device may be a mobile telephone (or "cellular" telephone) or a computer or the like having a mobile terminal, e.g., a portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile device that exchanges voice and/or data with the radio access network. The terminal device may also be a handheld device, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolving network, etc. with wireless communication functionality. The above is merely an example, and the practical application is not limited thereto.
The network device according to the embodiment of the present invention may include an access network device and a core network device. I.e. the wireless communication system further comprises a plurality of core networks for communicating with the access network devices. The access network device may be a long-term evolution (LTE) system, a next-generation (NR) system, or an evolved base station (evolutional node B, abbreviated as eNB or e-NodeB) macro base station, a micro base station (also called "small base station"), a pico base station, an Access Point (AP), a transmission point (transmission point, TP), a new generation base station (new generation Node B, gNodeB), or the like in an licensed assisted access long-term evolution (LAA-LTE) system.
TDD is one of full duplex communication technologies used in a mobile communication system, and is a technology for distinguishing a radio channel in time and continuing an uplink operation in a downlink operation of a frame period, corresponding to FDD.
FDD is one of full duplex communication technologies used in a mobile communication system, corresponding to TDD. FDD uses two separate channels for transmitting information downward and upward, respectively. In order to prevent mutual interference between adjacent transmitters and receivers, a guard band exists between the two channels.
Long term evolution (Long Term Evolution, LTE) cell reselection refers to the process by which a UE provides a service signal by monitoring signal quality of neighbor cells and serving cells in idle mode. When the signal quality and level of the neighbor cell meet the S criterion and meet a certain reselection criterion, the UE will access the cell to camp on. After the UE successfully camps, the measurement of the cell is continuously performed. The RRC layer calculates Srxlev (S criteria) according to the reference signal received power (Reference Signal Receiving Power, RSRP) measurement result, and compares it with Sintrasearch (same frequency measurement start threshold) and snondintersearch (different frequency/different system measurement start threshold) as a decision condition for whether to start neighbor cell measurement.
In view of the foregoing, embodiments of the present invention disclose a cell reselection control method, a terminal device, and a computer readable storage medium, which are configured to access a half-duplex cell as much as possible to perform a service by improving a reselection priority of the half-duplex cell, so as to save power consumption of the terminal device. The technical scheme of the invention will be described in detail below with reference to specific embodiments from the point of view of terminal equipment.
Example 1
Referring to fig. 1, fig. 1 is a flow chart of a cell reselection control method according to an embodiment of the present invention; as shown in fig. 1, the cell reselection control method may include:
101. the terminal device obtains cell information satisfying the reselection criterion.
When the cell reselection is needed, selecting the frequency point and the cell information meeting the reselection criterion according to the frequency point information carried by the system message SIB4/SIB 5. The reselection criteria may specifically include:
1. when the priority indicated by the system message is higher than the serving cell, the UE always performs measurements for these high priority cells;
2. for the same frequency/same priority cell, if the serving cell is smaller than or equal to Sintrasearch (same frequency measurement start threshold), the UE performs measurement, and is lower than non-measurement;
3. when the system message indicates that the priority is lower than the service cell, if the S value of the service cell is smaller than or equal to Snoninterrasearch (different frequency/different system measurement starting threshold), performing measurement, and is larger than non-measurement;
4. if the snondintersearch parameter is not broadcast in the system message, the UE starts inter-frequency cell measurement.
Wherein the S value is Srxlev (S criterion) in cell selection, formula: srxlev=qrxlevmeas- (qrxlevmin+qrxlevminoffset) -pcompuction, S criterion=rsrp value- { minimum reception level (typically 0-128 dbm) +minimum reception level bias (typically 0) } -power compensation (typically 0) of the measurement cell.
102. The terminal device determines a half duplex cell contained in the cell information.
Alternatively, the half-duplex cell may be a TDD cell or a half-duplex FDD cell.
The TDD cell may be a cell corresponding to a TDD frequency point, and the FDD cell is a cell corresponding to an FDD frequency point.
103. And the terminal equipment is accessed into the half-duplex cell when the signal intensity of the half-duplex cell is not less than the preset intensity.
It can be understood that when the signal strength of the half-duplex cell is not less than the preset strength, that is, the signal strength of the half-duplex cell can meet the service requirement of the terminal device, the terminal device is preferentially selected to access the half-duplex cell, and the terminal device can achieve the purpose of saving electricity by residing in the half-duplex cell.
Optionally, the preset strength may be determined by the user according to an actual application condition (for example, when the signal strength of the half duplex cell is high, the use of the user may not be affected, and the preset strength may be obtained by combining signal strength determination that does not affect normal use of the service for several times), or may be obtained by the network device according to tracking statistics and analyzing the signal strength, and then the signal strength is sent to the terminal device, which is not described herein again. It will be appreciated that the preset strength may be determined by counting the signal strength of several half duplex cells versus service usage. Preferably, the preset strength may be-95 dbm and-95 dbm is a minimum threshold value set by the terminal device for determining whether the signal strength of the half-duplex cell meets the service requirement.
104. And the terminal equipment is accessed into the half-duplex cell when the signal intensity of the half-duplex cell is smaller than the preset intensity but not smaller than the signal intensity of the full-duplex cell contained in the cell information.
When the signal strength of the half-duplex cell is smaller than the preset strength, but not smaller than the signal strength of the full-duplex cell contained in the cell information, the half-duplex cell is also preferentially selected.
It can be seen that, by implementing the above terminal device, the cell information satisfying the reselection criterion is obtained, so as to determine a half-duplex cell included in the cell information, if the determined signal strength of the half-duplex cell is not less than the preset strength, the half-duplex cell is accessed, and if the signal strength of the half-duplex cell is less than the preset strength but not less than the signal strength of the full-duplex cell included in the cell information, the half-duplex cell is accessed; therefore, when the embodiment of the invention meets the signal strength requirement, the reselection priority of the half-duplex cell is improved to access the half-duplex cell as much as possible for service, so that the electric quantity consumed by the terminal equipment for service is reduced as a whole, the purpose of saving electricity is achieved, and the service duration of the terminal equipment is prolonged.
Example two
Referring to fig. 2, fig. 2 is a flow chart of a cell reselection control method according to a second embodiment of the present invention; as shown in fig. 2, the cell reselection control method may include:
201. and when the terminal equipment is in an idle state, measuring frequency point information carried by the system information to obtain cell information meeting reselection criteria.
Exemplary, frequency point information carried by SIB4/SIB5 is measured, and cell information meeting the reselection criterion of cell reselection is obtained.
202. The terminal equipment judges whether the cell information comprises a half-duplex cell or not; if the half duplex cell is included, the process goes to step 203; if the half duplex cell is not included, step 206 is performed.
The half duplex cell is illustratively a TDD cell, and the terminal device first determines whether the cell information includes the TDD cell.
203. The terminal device determines whether the signal strength of the half duplex cell is not less than a preset strength, if so, performs step 204, and if so, performs step 205.
204. The terminal device accesses the half duplex cell.
After step 204 is performed, the process ends.
As an alternative embodiment, if the cell information includes a plurality of half-duplex cells, if the signal strength of at least one half-duplex cell is not less than the preset strength, selecting the first half-duplex cell from the half-duplex cells with the signal strength not less than the preset strength according to the reselection criterion, and accessing the first half-duplex cell. It may be appreciated that when there are multiple half-duplex cells, a first half-duplex cell may be selected from the multiple half-duplex cells with signal strengths not less than the preset strength according to the re-priority of the reselection criterion, and accessed, so that the terminal device preferentially selects the half-duplex cell for camping.
Illustratively, if a plurality of TDD cells with signal strength not less than-95 dbm are included, a first TDD cell is selected from the plurality of TDD cells according to a re-criterion and accessed.
205. The terminal device determines whether the signal strength of the half duplex cell is smaller than the signal strength of the full duplex cell included in the cell information, wherein if yes, step 206 is executed, and if not, step 204 is executed.
206. And executing a normal reselection procedure according to the reselection criteria.
It can be seen that, when the terminal device is in an idle state, the embodiment acquires the cell information meeting the re-criterion, and when the cell information includes a half-duplex cell, if the signal strength of the half-duplex cell is not less than the preset strength, or the signal strength of the half-duplex cell is not less than the preset strength but not less than the signal strength of the full-duplex cell included in the cell information, the half-duplex cell is selected to be accessed to perform the service under the half-duplex cell as much as possible, thereby saving electricity and prolonging the service duration; if the signal intensity of the half duplex cell is smaller than that of the full duplex cell, a normal reselection procedure is executed according to the reselection criteria to select a suitable cell for access.
It can be understood that if the half-duplex cell is a TDD cell, when the signal strength meets the service requirement, by improving the reselection priority of the TDD cell, as much as possible, the terminal device performs the service in the TDD cell, so as to reduce the electric quantity consumed when the terminal device performs the service as a whole, thereby achieving the purpose of saving power consumption and prolonging the service duration of the terminal device.
Example III
Referring to fig. 3, fig. 3 is a flow chart of a cell reselection control method according to a third embodiment of the present invention; as shown in fig. 3, the cell reselection control method may include:
301. and when the terminal equipment is in a connection state, measuring the frequency point information of the RRC reconfiguration message to obtain a measurement result, wherein the measurement result comprises the signal quality of the half-duplex cell to be measured indicated in the frequency point information of the RRC reconfiguration message and the signal quality of the full-duplex cell to be measured indicated in the frequency point information of the RRC reconfiguration message.
Optionally, the signal quality includes signal strength, RSRP, etc.
302. The terminal device determines whether the signal quality of the half duplex cell to be measured is better than the signal quality of the full duplex cell to be measured, wherein if yes, the step 303 is turned to, and if not, the step 304 is turned to.
303. And the terminal equipment reports a measurement report carrying the measurement result.
The terminal equipment counts the measurement results of all the frequency point cells by measuring the frequency point information in the RRC reconfiguration message, and if the signal quality of the half-duplex cell to be measured included in the measurement results is better than the signal quality of the full-duplex cell to be measured, the terminal equipment directly reports the measurement report carrying the measurement results.
For example, the measurement results of the TDD cell and the FDD cell are compared, and if the signal quality of the TDD cell is better than the signal quality of the FDD cell, i.e. the signal strength of the TDD cell is not less than the signal strength of the FDD cell, and/or the RSRP of the TDD cell is not less than the RSRP of the FDD cell, the measurement report is reported to the network device normally.
304. The terminal equipment judges whether the signal intensity of the half-duplex cell to be measured indicated by the measurement result is smaller than preset intensity; if not, go to step 305, if yes, go to step 303.
305. And the terminal equipment reports a measurement report carrying the measurement result and indicating the indication information of the preferred half-duplex cell to be measured.
If the signal quality of the TDD cell is not better than that of the FDD cell, judging whether the signal strength of the TDD cell is not less than-95 dbm, if not, modifying the signal quality of the TDD cell to be better than that of the FDD cell to indicate the preferred TDD cell, and reporting a measurement report to the network equipment; otherwise, reporting the measurement report normally without modification.
It can be seen that when the terminal device is in the connection state and the signal intensity of the half-duplex cell is not less than the preset intensity, the measurement result is properly adjusted and then reported to the network device, so that the network device directly instructs the terminal device to measure the half-duplex cell in priority next time, the terminal device performs service in the half-duplex cell as much as possible, the electric quantity consumed by the terminal device when performing service is reduced as a whole, the purpose of saving power consumption is achieved, and the service duration of the terminal device is prolonged.
