Embodiments of the invention

The present application provides a method, a storage medium, and a mobile phone for reducing the content of the UE capability signaling structure. To clarify and clarify the purpose, technical solutions, and effects of the present application, the present application is further described in detail below. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting.

Referring to FIG. 1 , FIG. 1 is a schematic flowchart of reducing UE capability signaling structure content according to an embodiment of the present disclosure. As shown in the figure, the method includes the following steps:

S10. Write the frequency band and CA information currently supported by the operator to the mobile phone in advance;

S20. When receiving the request for acquiring the capability of the UE sent by the network, acquiring the frequency band and CA information supported by the mobile phone, and the frequency band and CA information currently supported by the operator;

S30. Acquire intersection data of the two frequency bands and intersection data of the two CA information, configure UE capability signaling structure content according to the frequency band intersection data and CA information intersection data, and configure the configured UE capability signaling. The structure is reported to the network side.

Specifically, some operators have restrictions on the size of the mobile phone UE capability signaling structure. When the limit is exceeded, the mobile phone cannot access the network. In this case, it is usually necessary to upgrade the corresponding device on the network side to ensure that the mobile phone accesses the network normally, which brings great inconvenience to the operator and the user.

To solve the above problem, the present application calculates and acquires the intersection data of the two frequency bands and the intersection data of the two CA information by acquiring the frequency band and CA information supported by the mobile phone and the frequency band and CA information currently supported by the operator, according to The frequency band intersection data and the CA information intersection data are configured to configure the UE capability signaling structure body, and the configured UE capability signaling structure body is reported to the network side. Through this configuration, the application can effectively reduce the content of the UE capability signaling structure, thereby reducing the network load, and the present application can effectively solve the problem that the mobile phone cannot access the network due to excessive content of the UE capability signaling structure. , bringing great convenience to operators and users.

In some embodiments, the step S10, the frequency band and the CA information currently supported by the operator are written into the mobile phone in advance, and specifically includes:

S11. When the frequency band and CA information supported by the operator change, send a message to the mobile phone.

S12. After receiving the message, the mobile phone writes the frequency band and CA information currently supported by the operator to the corresponding NVRAM through the NVRAM read/write interface.

For example, an application is set in advance in the mobile phone, and the application is used to receive a message sent by the server. When the frequency band and the CA information supported by the operator change, the server sends the message to the application, and the application calls the message. And sending the message to the mobile phone framework layer (Framework), the framework sends the message to the RIL through the Socket communication, the RIL sends the message to the mobile phone Modem through the AT command, and the Modem reads and writes through the NVRAM. The interface writes the frequency band and CA information currently supported by the operator to the corresponding NVRAM.

In some embodiments, the format of the frequency band and CA information supported by the operator is an xml format, which corresponds to a PLMN format on the network side. For example, the format of the China Unicom PLMN 46001 is as follows:

<operatorinfo plmn=”46001”

Band=”1,3,8,38,39,40,41”

interCA=””

/>

That is to say, the frequency band (band) supported by China Unicom is 1, 3, 8, 38, 39, 40, 41, and the inter-band CA is empty.

In some embodiments, in the step S20, when the mobile phone acquires the PLMN to be accessed by the network side from the system message SIB1, it further acquires the request for acquiring the UE capability sent by the network side; When the request for acquiring the UE capability is obtained, the frequency band and CA information supported by the mobile phone and the frequency band and CA information currently supported by the operator are obtained.

In some embodiments, the step S30 is: acquiring intersection data of the two frequency bands and intersection data of the two CA information, and configuring UE capability signaling structure content according to the frequency band intersection data and the CA information intersection data. The reported UE capability signaling structure is reported to the network side, and specifically includes:

S31. Acquire intersection data of the two frequency bands and intersection data of the two CA information.

S32. Fill in frequency band intersection data in the rf-Parameters and rf-Parameters-v9e0 fields in the UE capability signaling structure.

S33. Fill in the CA information intersection data in the rf-Parameters-v1020 field in the UE capability signaling structure.

S34. Report the configured UE capability signaling structure to the network side.

Specifically, the frequency supported by the rf-Parameters in the UE Capability Signaling Structure (usCapabilityInformation) The band range of the band information is (1..maxFBI), and the maxFBI is 64, that is, the frequency supported by rf-Parameters. The band range of the band information can only be 1 to 64.

Frequency supported by rf-Parameters-v9e0 in the UE Capability Signaling Structure (usCapabilityInformation) The band information has a band range of (maxFBI-Plus1..maxFBI2), which is 65 to 256.

For example, when the frequency band supported by the mobile phone is LTE: B1/3/7/8/20/28A, the operator uses China Unicom as an example, and the supported band is LTE. B1/3/8/38/39/40/41, then the band intersection of the two is LTE B1/3/8. In other words, you only need to fill in the band information of LTE B1/3/8 in the rf-Parameters parameter.

In some embodiments, the CA information has the following three types: <1>. In-band continuous carrier aggregation; <2>. In-band non-contiguous carrier aggregation; <3>. Inter-band carrier aggregation.

Because of the in-band carrier aggregation, in-band carrier aggregation can be performed if the band exists. Inter-band carrier aggregation cannot be performed if the carrier that is aggregated with it does not exist. Therefore, the inter-band carrier aggregation is mainly described here. For example, the inter-band carrier aggregation supported by the mobile phone is Band3+Band7, Band3+Band20, and Band7+Band20. Therefore, since China Unicom does not support Band7 and Band20, these inter-band carrier aggregations are not written in the rf-Parameters-v1020 field.

Obviously, the configuration provided by the application can effectively reduce the content of the UE capability signaling structure, thereby reducing the network load, and effectively solving the problem that the mobile phone cannot access the network due to excessive content of the UE capability signaling structure.

Based on the above method, the present application further provides a storage medium in which a plurality of instructions are stored, the instructions being adapted to be loaded and executed by a processor:

The RIL sends the message to the mobile phone Modem by using an AT command;

The completed UE capability signaling structure is reported to the network side.
