In a general design, taking a game service of a mobile terminal as an example, the relevant characteristics of the game service are as follows: long connections, small data packets, low traffic, low latency requirements, low fault tolerance, and sensitivity to changes in the wireless network environment. Due to the sensing capability range of normal people, when the delay in the game service reaches the level of 100ms, the user can obviously feel the card pause, and the operation is not flexible; when the delay in the game reaches the 200ms level, the operation of the user and the game perception feedback can not be synchronized basically, and the user experience is seriously influenced. As can be seen from the network architecture shown in fig. 1A, the process of the mobile terminal interacting with the network device for game service data includes access network delay from the mobile terminal to the air interface of the network, and time consumption for transmitting IP data from the access network to the game server.

In view of the above situation, an embodiment of the present application provides a network access control method, in which a mobile terminal first updates a cell measurement policy of the mobile terminal, and then measures a target cell using radio frequency resources of a secondary component carrier SCC of the mobile terminal in a cell measurement period according to the updated cell measurement policy, and the updated cell measurement policy is used to indicate that resources used for cell measurement include the radio frequency resources of the secondary component carrier SCC, a cell to which the mobile terminal is currently accessed is a source cell, and the mobile terminal supports carrier aggregation, and a network in which the source cell is located and a network in which the target cell is located are heterogeneous mobile communication networks. Therefore, the mobile terminal measures the target cell by multiplexing the radio frequency resource of the SCC in the cell measurement period, so that interruption of user plane data transmission of the mobile terminal due to the use of the radio frequency resource of the PCC for measuring the target cell can be avoided, reduction of user plane data transmission delay of the mobile terminal is facilitated, and data transmission real-time performance is improved.

Embodiments of the present application will be described below with reference to the accompanying drawings.

Referring to fig. 2A, fig. 2A is a schematic flowchart of a cell measurement method provided in an embodiment of the present application, which is applied to a mobile terminal and specifically can be executed by an application processor, a baseband processor, or an SoC, where as shown in the figure, the cell measurement method includes:

s201, the mobile terminal updates a cell measurement strategy of the mobile terminal, the updated cell measurement strategy is used for indicating resources used by cell measurement to comprise radio frequency resources of a secondary member carrier (SCC), a cell accessed by the mobile terminal currently is a source cell, and the mobile terminal supports carrier aggregation.

The cell refers to a serving cell in a mobile communication system, and the serving cell may be, for example, a serving cell in an LTE communication system, a serving cell in a 5G system, or the like, which is not limited herein. The measurement process corresponding to the cell measurement policy is performed during a preset idle time slot, where the idle time slot is a periodic time slot, and as shown in fig. 2B, for example, a single-card mobile phone, the duration of the idle time slot may be 6ms, and the idle time slot of a dual-card mobile phone is generally longer.

In mobile communication technology, carrier aggregation refers to aggregation of two or more basic carrier transmission information to meet a larger bandwidth requirement. The third Generation Partnership Project (3 GPP) specifies that in an LTE-Advanced (LTE-a) system, a network device may be configured for a mobile terminal to operate in a carrier aggregation environment, wherein the mobile terminal may transmit information on a plurality of component carriers associated with one or more serving cells. The uplink component carrier may be configured as a Primary Component Carrier (PCC) by a higher layer (e.g., layer 2 or layer 3, layer 2 being a MAC layer as in fig. 1E, layer 3 being an RLC layer as in fig. 1E) in the LTE-a system, and the other component carriers being configured as Secondary Component Carriers (SCCs). The PCC generally takes charge of uplink control information of layer 1 (such as the PHY layer in fig. 1E), such as ACK/NACK of downlink data, scheduling request, and transmission of periodic CSI information, the SCC generally takes charge of data transfer, and the SCC has a reduced utilization degree and is generally not used for performing data transmission in an idle timeslot period.

S202, the mobile terminal measures a target cell by using the radio frequency resource of the SCC of the mobile terminal in a cell measurement period according to the updated cell measurement strategy, wherein the network where the source cell is located and the network where the target cell is located are heterogeneous mobile communication networks.

The source cell may be, for example, a serving cell of an LTE system, and the target cell may be, for example, a serving cell of a 5G system, which is not limited herein.

If the mobile terminal supports the dual-card dual-standby mode and includes the first radio frequency system corresponding to the primary card and the second radio frequency system corresponding to the secondary card, the radio frequency resource of the secondary component carrier SCC may include the second radio frequency system. If the mobile terminal supports dual-card dual standby (single-pass system) and the main card and the auxiliary card correspond to the same radio frequency system, the radio frequency resources of the auxiliary component carrier SCC include the radio frequency system. If the mobile terminal only supports a single card and includes a single set of radio frequency system, the radio frequency resources of the secondary component carrier SCC include the single set of radio frequency system. The specific working principle of each mode is realized and widely applied, and the detailed description is omitted here.

In one possible example, before the mobile terminal updates the cell measurement policy of the mobile terminal, the method further includes: the mobile terminal receives a cell measurement strategy updating message from a target server; the cell measurement strategy update message is used for indicating to update the cell measurement strategy of the mobile terminal.

The target server may be, for example, a developer server of a target application currently running on the mobile terminal. In the specific implementation, in order to ensure that the current user plane data state of the mobile terminal is maintained in a better state, the mobile terminal may periodically send a data state index to the target server, the target server comprehensively predicts the data requirement of the mobile terminal to determine that the cell measurement policy of the mobile terminal needs to be updated, and issues and receives a cell measurement policy update message from the application server.

Therefore, in this example, the mobile terminal can dynamically update the cell measurement policy according to the message sent by the target server, and the target server can accurately evaluate the data requirement of the mobile terminal, so that the mobile terminal can be accurately instructed to update the cell measurement policy to better support data transmission, and the data transmission stability is improved.

In one possible example, before the mobile terminal updates the cell measurement policy of the mobile terminal, the method further includes: and the mobile terminal detects the network connection state of the source cell, and the network connection state is used for updating the cell measurement strategy of the mobile terminal by the mobile terminal.

In a specific implementation, the mobile terminal may measure the source cell, and obtain indexes such as Reference Signal Receiving Power (RSRP) or Reference Signal Received Quality (RSRQ) to evaluate the network connection state of the source cell.

The specific implementation manner of the mobile terminal updating the cell measurement policy of the mobile terminal according to the network connection state may be: and the mobile terminal detects that the RSRP is smaller than a preset RSRP, or detects that the RSRQ is smaller than the preset RSRQ, and updates the cell measurement strategy of the mobile terminal.

Therefore, in this example, the mobile terminal can reuse the measurement result of the source cell, update the cell measurement strategy in the weak signal scene, and improve the flexibility and convenience of measurement configuration.

In one possible example, the mobile terminal updating the cell measurement policy of the mobile terminal includes: the mobile terminal updates the radio frequency resource used by the mobile terminal for executing the cell measurement from the radio frequency resource of a Primary Component Carrier (PCC) to the radio frequency resource of the SCC; and sending an updated cell measurement strategy to the source cell, wherein the updated cell measurement strategy is used for indicating the source cell to detect the service data of the mobile terminal in the cell measurement period.

In the conventional cell measurement strategy, the source cell (i.e. the network device of the source cell) generally does not perform user plane data transmission with the mobile terminal during the idle time slot.

As can be seen, in this example, the mobile terminal notifies the source cell, so that the source cell can synchronously transmit the user plane service data in the idle time slot, thereby ensuring the stability of data transmission of the mobile terminal.

In one possible example, the method further comprises: and the mobile terminal transmits the service data of the mobile terminal by using the radio frequency resource of the PCC within the cell measurement period.

The service data transmitted by the radio frequency resource of the PCC includes downlink data and uplink data. As shown in fig. 2C, after the mobile terminal updates the cell measurement policy, the mobile terminal may transmit service data of the mobile terminal by using the radio frequency resource of the PCC in the cell measurement period.

As can be seen, in this example, after the mobile terminal updates the cell measurement policy, the user plane data may be continuously transmitted in the idle timeslot where data transmission is originally required to be interrupted, so as to improve the continuity and stability of data transmission.

In one possible example, the cell measurement policy includes an inter radio access technology IRAT cell measurement policy or a cell measurement policy of a secondary card of the mobile terminal.

Wherein the IRAT measurements include at least one of: received Signal Strength Indication (RSSI) measurement, Frequency Correction Channel (FCCH) detection, and Base Station Identity Code (BSIC) confirmation.

In one possible example, the foreground of the mobile terminal runs a target application, and the target application may be a game application, a video application, or the like, which is not limited herein. Illustratively, the running interface of the target application is a multi-user online battle arena (MOBA) scene interface.

In specific implementation, the mobile terminal may analyze a plurality of data packets through sampling by the baseband processor, identify an MOBA scene of a target application program running in the foreground through attributes such as format of the data packets, and acquire scene information sent by the foreground application program through the application processor, so that the operating system can timely know the MOBA scene of the target application program running in the foreground, which is not limited uniquely here. That is to say, the triggering condition for the mobile terminal to execute the step S201 may be that the mobile terminal detects that the current operation scene is the MOBA scene, so as to implement the exclusive optimization control for the MOBA scene.

Therefore, in the example, the mobile terminal only performs identification and exclusive optimization control on the MOBA scene, so that resource balance is facilitated, and cruising ability is improved.

Referring to fig. 3, in accordance with the embodiment shown in fig. 2A, fig. 3 is a schematic flowchart of a cell measurement method provided in the embodiment of the present application, which is applied to a mobile terminal, and is exemplary and executable by an application processor or a baseband processor or a SoC of the mobile terminal, which is not limited herein. As shown in the figure, the cell measurement method includes:

S302, the mobile terminal updates the radio frequency resource used by the mobile terminal for executing cell measurement from the radio frequency resource of a Primary Component Carrier (PCC) to the radio frequency resource of the SCC;

s303, the mobile terminal sends an updated cell measurement policy to the source cell, where the updated cell measurement policy is used to instruct the source cell to detect the service data of the mobile terminal in the cell measurement period.

S305, the mobile terminal transmits the service data of the mobile terminal by using the radio frequency resource of the PCC within the cell measurement period.

In addition, the mobile terminal can dynamically update the cell measurement strategy according to the message sent by the target server, and the target server can accurately evaluate the data requirement of the mobile terminal, so that the mobile terminal can be accurately indicated to update the cell measurement strategy to better support data transmission, and the data transmission stability is improved.

In addition, the mobile terminal informs the source cell, so that the source cell can synchronously transmit the user plane service data in an idle time slot, and the stability of data transmission of the mobile terminal is ensured.

In addition, after the mobile terminal updates the cell measurement strategy, the user plane data can be continuously transmitted on the idle time slot which originally needs to interrupt the data transmission, so that the continuity and the stability of the data transmission are improved.
