For example, the network device may be a base station (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile Communication, GSM) or code division multiple access (Code Division Multiple Access, CDMA) communication system, a base station (NodeB, NB) in a wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, an evolved base station (Evolutional Node B, eNB or eNodeB) in an LTE system, or a relay station, an access point, a vehicle device, a wearable device, a network device in a future 5G network or a network after 5G network (gNB) or a network device in a future evolved public land mobile network (Public Land Mobile Network, PLMN) network, etc.
First, an application scenario of the communication method provided by the present application will be described with reference to fig. 1.
Fig. 1 is a schematic view of an application scenario provided by the present application. As shown in fig. 1, includes: a terminal (UE), a first SIM, a second SIM, a first network device (gNB 1), a second network device (gNB 2), a third network device (gNB 3), a fourth network device (gNB 4).
The first SIM and the second SIM are two SIMs disposed within the UE. When the UE is in DSDA mode, for example, the UE may make a call through the first SIM while the UE may be on the internet through the second SIM, or the UE may make a call through the first SIM while the UE may receive an incoming call alert through the second SIM, etc. Therefore, when the UE is in the DSDA mode, the user experience of the UE can be improved.
For the first SIM, gNB 1 is a network device covering the current serving cell of the first SIM, and gNB 3 is a network device covering a neighbor cell (of the current serving cell) of the first SIM. In the process of switching the UE from the current serving cell to the neighbor cell, the UE changes from communicating with the gNB 1 through the first SIM to communicating with the gNB 3 through the first SIM.
For the second SIM, gNB 2 is a network device covering the current serving cell of the second SIM, and gNB 4 is a network device covering a neighbor cell (of the current serving cell) of the second SIM. In the process of switching the UE from the current serving cell to the neighbor cell, the UE changes from communicating with the gNB 2 through the second SIM to communicating with the gNB 4 through the second SIM.
The first SIM and the second SIM of some terminals currently multiplex the antenna resources of one SIM, so that in order to enable the terminal to be in DSDA mode, the capabilities of the first SIM and the second SIM have the limitations shown in (11) - (15) below.
(11) The frequency bands (including single frequency band or multiple frequency bands) supported by the first SIM and the second SIM are combined together, so that the frequency band requirement that the first SIM and the second SIM are in a connected state at the same time can be met.
(12) The CC numbers supported by the first SIM and the second SIM are combined together, so that the CC number requirement that the first SIM and the second SIM are in a connected state at the same time can be met.
(13) The multiple-input multiple-output (multiple input multiple output, MIMO) layer numbers supported by the first SIM and the second SIM are combined together, so that the MIMO layer number requirement that the first SIM and the second SIM are in a connection state at the same time can be met.
(14) The bandwidths supported by the first SIM and the second SIM are combined together, and the first SIM and the second SIM are simultaneously in the connected state of bandwidth requirements.
(15) The transmit powers supported by the first SIM and the second SIM are combined together, and the first SIM and the second SIM are simultaneously in a connected state of bandwidth requirements.
When any one of (11) - (15) is not satisfied, the terminal cannot be in DSDA mode.
When the terminal is in the DSDA mode, the first SIM and the second SIM are in a connection state at the same time, and resources of the terminal can be shared. Therefore, in the case where the above (11) to (15) are satisfied, there is a capability reduction in both the capabilities of the first SIM and the second SIM as compared with the respective original capabilities, as shown in (21) to (25) below.
(21) The frequency bands supported by the first SIM and the second SIM are subsets of the frequency bands supported by the corresponding SIM.
(22) The number of CCs supported by the first SIM and the second SIM is smaller than or equal to the maximum number of CCs supported by the corresponding SIM.
(23) The number of MIMO layers supported by the first SIM and the second SIM is smaller than or equal to the maximum number of MIMO layers supported by the corresponding SIM.
(24) The bandwidths supported by the first SIM and the second SIM are respectively smaller than or equal to the maximum bandwidth supported by the corresponding SIM.
(25) The transmit power supported by each of the first SIM and the second SIM is less than or equal to the transmit power supported by the corresponding SIM.
In the current DSDA feature discussion of the Multiple Universal Subscriber Identity Module (MUSIM), the terminal actively sends terminal side information (UE Assistance Information, UAI) of "capability reduction" to the network device informing the network device that the terminal is currently in DSDA mode and that the capability of the SIM is reduced.
When the terminal is in DSDA mode, the configuration and capabilities of two SIMs in the terminal are mutually affected (i.e. need to satisfy (11) - (15)), so that the configuration of one SIM changes and the capabilities of the other SIM also changes. In this way, the terminal may frequently send capability change information of each SIM to the network device through the UAI, thereby resulting in a large signaling overhead.
In view of this, the present application provides a communication method in which capability change information of a SIM is carried through an existing measurement report (Measurement Report ), thereby saving signaling overhead.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flow chart of a communication method according to an embodiment of the present application. As shown in fig. 2, the method includes, but is not limited to:
S201, the terminal sends a measurement report corresponding to the SIM to the network equipment when the terminal is in a DSDA mode; wherein the measurement report includes capability restriction information for each of at least one neighbor cell of the current serving cell of the SIM.
Optionally, the SIM is a first SIM or a second SIM of the terminal.
In an embodiment of the present application, the measurement report further includes: the measurement result of the current serving cell of the SIM and/or the measurement result of each of the at least one neighbor cell of the current serving cell of the SIM.
Optionally, the measurement results include, but are not limited to, a received signal strength Indicator (RECEIVED SIGNAL STRENGTH Indicator, RSSI), a reference signal received Power (REFERENCE SIGNAL RECEIVING Power, RSRP), or a signal to noise ratio (Signal to Noise Ratio, SNR).
In the case where the SIM is a first SIM, the network device is the first network device corresponding to the first SIM (i.e., the network device covering the current serving cell of the first SIM). The terminal may send a measurement report corresponding to the first SIM to the first network device. The measurement report corresponding to the first SIM includes capability restriction information for each of at least one neighbor cell of the current serving cell of the first SIM.
In the case where the SIM is a second SIM, the network device is a second network device corresponding to the second SIM (i.e., a network device that covers the current serving cell of the second SIM). The terminal may send a measurement report corresponding to the second SIM to the second network device. The measurement report corresponding to the second SIM includes capability restriction information for each of at least one neighbor cell of the current serving cell of the second SIM.
Alternatively, the terminal may simultaneously send a measurement report corresponding to the first SIM to the first network device and send a measurement report corresponding to the second SIM to the second network device.
Alternatively, the capability restriction information of each of at least one neighbor cell of the current serving cell of the SIM may be referred to as temporary capability restriction (Temporary capability restriction) information of the SIM.
Optionally, the capability restriction information of each of the at least one neighbor cell of the current serving cell of the SIM may be configured within a preset field (MeasResultNR) of the measurement report.
Unlike the related art, in the related art, the terminal frequently transmits capability change information of each SIM to the network device through the UAI, resulting in a large signaling overhead. In the application, the measurement report carries the capability limit information (also called the capability change information of the SIM) of each neighboring cell in at least one neighboring cell of the current service cell of the SIM, so that the capability change information of the SIM can be prevented from being transmitted by adopting additional signaling, thereby saving signaling overhead.
In addition, unlike the related art, in the related art, the UAI includes only the capability restriction information of the current serving cell, but does not include the capability restriction information of each of at least one neighbor cell of the current serving cell, thereby causing the network device to instruct the cell in which the terminal is handed over to be a neighbor cell that does not support the terminal in the DSDA mode, and thus causing the terminal to be unable to continue in the DSDA mode. In the embodiment of the application, the measurement report also comprises the capacity limit information of each neighbor cell in at least one neighbor cell of the current service cell, so that the situation that the cell which indicates the terminal to switch is a neighbor cell which does not support the terminal to be in a DSDA mode after the network equipment makes a cell switching decision can be avoided, and the terminal is ensured to be continuously in the DSDA mode.
Optionally, the at least one neighbor cell is a plurality of neighbor cells of the current serving cell. A plurality of neighboring cells are configured by a network device for a terminal.
Alternatively, the at least one neighboring cell may be a neighboring cell in which the capability restriction information is changed among the plurality of neighboring cells.
Unlike the related art, in the related art, the terminal may report capability change information of the SIM through the terminal capability information, but since the capability change information of the SIM includes capability restriction information of a current serving cell and/or capability restriction information of each of at least one neighbor cell of the current serving cell, the capability restriction information of some neighbor cells may not change, and thus the capability restriction information of neighbor cells may be redundantly reported. In the application, the measurement report can include the capacity limit information of the current service cell and/or the capacity limit information of each neighbor cell in at least one neighbor cell of the current service cell, and the at least one neighbor cell can also be a neighbor cell with changed capacity limit information in a plurality of neighbor cells, thereby avoiding redundant reporting of the capacity limit information of the neighbor cells and saving signaling overhead.
Unlike the related art, in the related art, the terminal may report capability change information of the SIM through the terminal capability information, where the capability change information includes capability restriction information corresponding to each of all the frequency bands supported by the terminal, so that a data size is large, which may result in a longer code stream of the terminal capability information. In the application, the measurement report comprises the capability limit information of at least one neighbor cell, but not the capability limit information corresponding to each frequency band, so the data volume is smaller, and the signaling overhead is saved under the condition of not greatly increasing the measurement report.
