Detailed Description
Before the technical scheme of the embodiment of the invention is described in detail, the related technology is described first.
In the related art, in the LTE communication system, when the terminal device performs cell selection, the following two methods may be used: (1) Searching based on the stored information frequency points, namely searching only the frequency points stored before; (2) Full-band searching, namely searching all frequency points on all frequency bands supported by the terminal. If the network configures LTE inter-frequency or inter-system measurement, that is, configures LTE measurement in GSM or WCDMA, the terminal may initiate LTE measurement when the measurement condition is satisfied according to configuration information issued by the network.
In the related art, with the gradual progress of 5G NR construction, multiple operators access in an LTE cell sharing manner in an access side network. The shared cells built by some operators may employ the following strategies: the user terminal of the operator can reside in the cell and acquire normal service; for user terminals of other operators, the cell is only used as an anchor cell of the NSA network for adding SCG; if the terminal cannot add SCG and is always resident in the cell, the network allocates little uplink and downlink resources to the terminal, and the data service (such as browsing web pages, games, video, etc.) requirement of the terminal cannot be met.
However, in the related art, identification judgment and optimization processing are not performed on similar shared cells, so when a terminal resides in a shared cell which is not built by the operator, the terminal equipment can cause serious problems due to insufficient network allocation resources, thereby affecting user experience.
Based on this, in various embodiments of the present invention, when cell selection is performed in a shared cell, a terminal device determines at least one frequency point corresponding to an operator to which the terminal device belongs; the shared cell is a shared cell established in a dual-connection architecture; the terminal equipment does not support a dual-connection mode; and the terminal equipment performs cell selection based on at least one frequency point corresponding to an operator to which the terminal equipment belongs.
The invention will be described in further detail with reference to the accompanying drawings and specific examples.
Fig. 1 is a schematic diagram of a system structure to which a cell selection method according to an embodiment of the present invention is applied, where, as shown in fig. 1, the system includes a terminal 101, a primary base station 102, and a secondary base station 103; wherein, the liquid crystal display device comprises a liquid crystal display device,
terminal 101 may establish an air interface connection with primary base station 102 (also referred to as a primary node) to enable communication with primary base station 102; the terminal 101 may also establish an air interface connection with the secondary base station 103 (also referred to as a secondary node) to enable communication with the secondary base station 103.
In the dual connectivity mode, the terminal 101 establishes two connections with the primary base station 102 or the secondary base station 103, wherein the primary base station 102 is mainly responsible for transmitting signaling and the secondary base station 103 is responsible for transmitting data. The technical scheme of the embodiment of the application mainly aims at the terminal which does not support the dual-connection mode.
The types of the primary base station 102 and the secondary base station 103 shown in fig. 1 may be the same or different. In one example, the primary base station 102 is an LTE base station and the secondary base station 103 is an NR base station. In another example, the primary base station 102 is an NR base station and the secondary base station 103 is also an NR base station. In yet another example, the primary base station 102 is an NR base station and the secondary base station 103 is an LTE base station. The embodiment of the present application does not limit the types of the primary base station 102 and the secondary base station 103.
The embodiment of the application provides a cell selection method, and fig. 2 is a schematic diagram of an implementation flow of the cell selection method in the embodiment of the application; as shown in fig. 2, the method includes:
step 201: and determining at least one frequency point corresponding to an operator to which the terminal equipment belongs.
Step 202: and selecting a cell in the shared cell where the terminal equipment is located based on the at least one frequency point.
Wherein the shared cell is a shared cell established in a dual-connection architecture; the terminal device does not support the dual connectivity mode.
Here, in step 201, the operator to which the terminal device belongs may refer to an operator to which a subscriber identity module (SIM, subscriber Identity Module) currently used by the terminal device belongs. If the terminal equipment is dual-card terminal equipment, the operator to which the SIM card 1 belongs is the operator to which the terminal equipment belongs, assuming that the SIM card 1 is currently used.
Here, in step 202, the shared cell may refer to a shared cell established in the primary base station, or may refer to a shared cell established in the secondary base station. The shared cell may be a shared cell established by a certain operator, so that for terminal devices of the operator, the terminal devices can reside in the shared cell and enjoy normal data service; for terminal equipment of other operators, if the terminal equipment can use a shared cell as an anchor cell to carry out SCG connection, the terminal equipment can also reside in the shared cell and enjoy normal data service, but if the terminal equipment can not use the shared cell as an anchor cell to carry out SCG connection, namely, a dual connection mode is not supported, the terminal equipment can carry out cell search by determining a frequency point corresponding to the operator to which the terminal equipment belongs and reside on the cell of the frequency point corresponding to the operator to which the terminal equipment belongs so as to ensure the normal operation of the data service.
Here, in practical application, the terminal device may search for a target frequency point with a cell signal strength greater than or equal to a threshold value from at least one frequency point corresponding to an operator to which the terminal device belongs, and reside in a cell corresponding to the target frequency point.
The following describes in detail how cell selection is performed for a terminal device that performs cell selection in a shared cell and does not support dual connectivity.
In case 1, for a terminal device that performs cell selection in a shared cell and does not support dual connectivity, when the terminal device is in an idle state, cell search may be performed based on at least one locally stored frequency point corresponding to an operator to which the terminal device belongs.
In practical application, aiming at the terminal equipment which performs cell selection in the shared cell and does not support double connection, when the terminal equipment is in an idle state to search the frequency points stored before searching, the terminal equipment only selects all the frequency points of the operator to search.
Based on this, in an embodiment, the determining, by the terminal device, at least one frequency point corresponding to an operator to which the terminal device belongs includes:
determining at least one frequency point corresponding to an operator to which the terminal equipment belongs from a locally stored frequency point database; the frequency point database stores the corresponding relation between the frequency points and operators.
Table 1 is an illustration of a frequency point locally stored in a terminal device, as shown in table 1, where the frequency point locally stored in the terminal device includes a frequency point of an operator 1, a frequency point of an operator 2, and a frequency point of an operator 3, and if the terminal device corresponds to the operator 3, only a target frequency point with a cell signal strength greater than or equal to a threshold value is searched from multiple frequency points corresponding to the operator 3, and no search is performed for frequency points of other operators.
| Operators (operators) | Frequency point |
| Operator 1 | Frequency point 1 and frequency point 2 |
| Operator 2 | Frequency point 3, frequency point 4, frequency point 5 |
| Operator 3 | Frequency point 6, frequency point 7 |
TABLE 1
In an example, as shown in fig. 3, a procedure for a terminal device to perform cell selection in a shared cell is described, including:
step 301: the terminal equipment determines at least one frequency point corresponding to an operator to which the terminal equipment belongs from a locally stored frequency point database;
step 302: and the terminal equipment performs cell selection on the shared cell where the terminal equipment is located based on at least one frequency point corresponding to an operator to which the terminal equipment belongs.
Here, the shared cell is a shared cell established in a dual connectivity architecture; the terminal device does not support dual connectivity mode. The frequency point database stores the corresponding relation between the frequency points and operators.
Here, the terminal device performs cell selection in the shared cell based on at least one frequency point corresponding to the operator to which the terminal device belongs, and has the following advantages:
(1) Aiming at the terminal equipment which performs cell selection in the shared cell and does not support double connection, the cell selection is performed in the shared cell based on at least one frequency point corresponding to an operator to which the terminal equipment belongs, and the terminal equipment can reside in the cell corresponding to the operator to which the terminal equipment belongs so as to ensure normal operation of data service.
(2) Compared with the mode that the shared cell cannot be used as an anchor cell for SCG connection in the related technology, so that the shared cell cannot be resided, the terminal equipment can be ensured to enjoy normal data service, and therefore user experience is improved.
In case 2, for a terminal device that performs cell selection in a shared cell and does not support dual connectivity, when the terminal device is in an idle state, cell search may be performed based on a full frequency band corresponding to an operator to which the terminal device belongs.
In practical application, aiming at the terminal equipment which performs cell selection in the shared cell and does not support dual connection, when the terminal equipment is in an idle state to perform full-band searching on a proper cell, the terminal equipment only selects all frequency points of the operator to perform searching.
Based on this, in an embodiment, the determining, by the terminal device, at least one frequency point corresponding to an operator to which the terminal device belongs includes:
and determining at least one frequency point corresponding to an operator to which the terminal equipment belongs from the frequency band supported by the terminal equipment.
Specifically, for each frequency band in a plurality of frequency bands supported by the terminal device, the terminal device determines at least one frequency point corresponding to an operator to which the terminal device belongs from a plurality of frequency points corresponding to the corresponding frequency band.
Table 2 is an illustration of frequency bands of different operators, and as shown in table 2, it is assumed that the frequency bands include the frequency band of the operator 1, the frequency band of the operator 2, and the frequency band of the operator 3, and it is assumed that the terminal device corresponds to the operator 3, only the target frequency point with the cell signal strength greater than or equal to the threshold value is searched from the full frequency band corresponding to the operator 3, and no search is performed for the full frequency bands of other operators.
| Frequency band corresponding to operator | Frequency point |
| Frequency band corresponding to operator 1 | Frequency point 1 and frequency point 2 |
| Frequency band corresponding to operator 2 | Frequency point 3, frequency point 4, frequency point 5 |
| Frequency band corresponding to operator 3 | Frequency point 6, frequency point 7 |
TABLE 2
In an example, as shown in fig. 4, a procedure for a terminal device to perform cell selection in a shared cell is described, including:
Step 401: for each frequency band in a plurality of frequency bands supported by terminal equipment, the terminal equipment determines at least one frequency point corresponding to an operator to which the terminal equipment belongs from a plurality of frequency points corresponding to the corresponding frequency band;
step 402: and the terminal equipment performs cell selection on the shared cell where the terminal equipment is located based on at least one frequency point corresponding to an operator to which the terminal equipment belongs.
Here, the shared cell is a shared cell established in a dual connectivity architecture; the terminal device does not support dual connectivity mode. The frequency point database stores the corresponding relation between the frequency points and operators.
Here, the terminal device performs cell selection in the shared cell based on at least one frequency point corresponding to the operator to which the terminal device belongs, and has the following advantages:
(1) Aiming at the terminal equipment which performs cell selection in the shared cell and does not support double connection, the cell selection is performed in the shared cell based on at least one frequency point corresponding to an operator to which the terminal equipment belongs, and the terminal equipment can reside in the cell corresponding to the operator to which the terminal equipment belongs so as to ensure normal operation of data service.
(2) Compared with the mode that the shared cell cannot be used as an anchor cell for SCG connection in the related technology, so that the shared cell cannot be resided, the terminal equipment can be ensured to enjoy normal data service, and therefore user experience is improved.
In case 3, for a terminal device that performs cell selection in a shared cell and does not support dual connectivity, when the terminal device is in an idle state, cell search may be performed based on a frequency point of a first network corresponding to an operator to which the terminal device belongs.
In practical application, for a terminal device which performs cell selection in a shared cell and does not support dual connection, when the terminal device is in an idle state to search for a suitable cell, if the terminal device selects all frequency points of the operator to search for the suitable cell, the terminal device can determine the frequency point of the first network corresponding to the operator to which the terminal device belongs to perform cell search.
Based on this, in an embodiment, the method further comprises:
when the at least one frequency point does not contain a target frequency point, determining at least one frequency point in a first network, which corresponds to an operator to which the terminal equipment belongs; the first network is different from a second network corresponding to the shared cell, and the target frequency point is a frequency point with signal strength greater than or equal to a threshold value.
Specifically, the terminal device may determine whether the at least one frequency point includes a target frequency point with a signal strength greater than or equal to a threshold value; and when the at least one frequency point does not contain the target frequency point with the signal strength larger than or equal to the threshold value, the terminal equipment determines at least one frequency point which corresponds to an operator to which the terminal equipment belongs and is in the first network.
For example, assume that a first base station in a dual connectivity architecture establishes a shared cell, the first base station is an LTE base station, and the second base station is a 5G NR base station. When the terminal equipment determines that at least one frequency point corresponding to an operator to which the terminal equipment belongs searches an LTE cell, if a proper LTE cell cannot be found, determining that at least one frequency point of a first network such as 3G WCDMA or 2G GSM corresponding to the operator to which the terminal equipment belongs carries out cell searching again, and if a proper cell is found, residing in the cell; if a suitable cell cannot be found, cell search can be performed by using at least one frequency point corresponding to the non-own operator.
Here, in actual application, the terminal device judges whether the at least one frequency point includes a target frequency point with signal strength greater than or equal to a threshold value; when it is determined that the at least one frequency point does not include a target frequency point with signal strength greater than or equal to a threshold, the terminal device may also perform cell search by using at least one frequency point corresponding to a non-home operator, and if a suitable cell is found, reside in the cell; if a proper cell cannot be found, determining at least one frequency point in a first network corresponding to an operator to which the terminal equipment belongs; and searching a cell on the basis of at least one frequency point of the first network, which corresponds to an operator to which the terminal equipment belongs.
In case 4, for a terminal device that performs cell selection in a shared cell and does not support dual connection, when the terminal device is in a connected state, the network side may send a measurement request to the terminal device, where the measurement request may carry multiple frequency points, and the terminal device only measures the frequency points corresponding to an operator to which the terminal device belongs.
In practical application, after the terminal equipment performs cell selection and residents based on the frequency points corresponding to the operator to which the terminal equipment belongs, if the terminal equipment enters a connection state from an idle state and receives a frequency point measurement request of network configuration, the terminal equipment can monitor and measure only part of the frequency points in the database of all frequency points of the operator to which the terminal equipment belongs.
Based on this, in an embodiment, the terminal device is in a connected state; the method further comprises the steps of:
the terminal equipment receives a measurement request sent by network equipment; the measurement request carries a plurality of frequency points;
the terminal equipment analyzes the measurement request to obtain a plurality of frequency points; and selecting at least one frequency point corresponding to an operator to which the terminal equipment belongs from the plurality of frequency points.
Measuring the at least one frequency point to obtain a first measurement result; the first measurement result is used for the network equipment to determine a target frequency point with the cell signal strength greater than or equal to a threshold value from the at least one frequency point, and control the terminal equipment to switch to a cell corresponding to the target frequency point.
In practical application, the terminal device may search for multiple target frequency points from the frequency points corresponding to the operators to which the terminal device belongs, so that one frequency point which is not easy to switch to the cell of the non-own operator can be selected from the multiple target frequency points as a final target frequency point.
Based on this, in an embodiment, when the number of the target frequency points is plural, the controlling terminal device switches to a cell corresponding to the target frequency point, including:
sorting the cells corresponding to the target frequency points according to the difficulty level of switching to the non-self operator to obtain a sorting result;
selecting a cell with the highest difficulty of switching to a non-self operator from the sequencing result as a cell to be switched;
and controlling the terminal equipment to switch to the cell to be switched.
In an example, as shown in fig. 5, a procedure for a terminal device to perform cell selection in a shared cell is described, including:
Step 501: the terminal equipment determines at least one frequency point corresponding to an operator to which the terminal equipment belongs;
step 502: and the terminal equipment searches the target frequency point with the cell signal strength greater than or equal to a threshold value from the at least one frequency point.
The shared cell is a shared cell established in a dual-connection architecture; the terminal device does not support dual connectivity mode.
Step 503: the terminal equipment judges whether a plurality of target frequency points are searched; when a plurality of target frequency points are searched, step 504 is performed;
step 504: sorting the cells corresponding to the target frequency points according to the difficulty level of switching to the non-self operator to obtain a sorting result;
step 505: selecting a cell with the highest difficulty of switching to a non-self operator from the sequencing result as a cell to be switched; and controlling the terminal equipment to switch to the cell to be switched.
Here, the terminal device performs cell selection in the shared cell based on the cell with the greatest difficulty of switching to the non-home operator corresponding to the operator to which the terminal device belongs, and has the following advantages:
aiming at the terminal equipment which performs cell selection in the shared cell and does not support double connection, if a plurality of target frequency points are searched based on at least one frequency point corresponding to an operator to which the terminal equipment belongs, the cell selection is performed based on a cell which corresponds to the operator to which the terminal equipment belongs and has the greatest difficulty of switching to a non-self operator, so that the normal service provided by the cell of the self operator can be ensured to be enjoyed.
In actual application, after receiving a frequency point measurement request of network configuration, the terminal does not measure, reselect or report the measurement of the frequency points which are not in the database of all LTE frequency points of the operator.
Based on this, in an embodiment, the method further comprises:
