In the integrity protection process, a terminal device sends a session establishment request to a network side device, the session establishment request carries an integrity protection data rate value of the terminal device, and the network side device judges whether the integrity protection data rate value of the terminal device can meet the requirements of a service according to the integrity protection requirements of the service, so as to determine whether the session establishment related to the service is supported. Therefore, the maximum integrity protection data rate value supported by each terminal device is determined and reported by the device, the network participation degree is not enough, the flexibility is not realized, and the session establishment efficiency is lower.

The embodiment of the application also relates to network side equipment. The network side device may be a device for communicating with a terminal device, for example, may be an access network device, such as a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Base Station (NodeB, NB) in a WCDMA system, an evolved Node B (eNB or eNodeB) in an LTE system, or a relay Station, an access point, a vehicle-mounted device, a wearable device, and a Base Station, a relay Station, or an access point in a future 5G network or a network after 5G; may be core network equipment, such as SGSN (Serving GPRS Support Node) in GSM system, MME (Mobility Management Entity) in LTE system, etc.; or may be an application server device such as a video application server, a car networking application server, or the like.

Fig. 1 is a system architecture diagram of a communication method according to an embodiment of the present application. As shown in fig. 1, the terminal device 11 and the terminal device 12 are terminal devices residing in or accessing to an access network device 13, and the access network device 13 is connected to a core network device 14. The access network device 13 receives the data transmitted by the terminal device 11 and the terminal device 12, and transmits the data to the core network device 14. The core network device 14 prestores integrity protection configuration information, and the access network device 13 receives the integrity protection configuration information issued by the core network device and sends the integrity protection configuration information to the terminal device 11 and the terminal device 12.

Fig. 2 is a flowchart illustrating a communication method according to an embodiment of the present application. As shown in fig. 2, the communication method 200 provided in this embodiment includes the following steps:

s201, the network side equipment sends integrity protection configuration information to the terminal equipment; the configuration information includes one or more integrity protection data rate values;

s202, the terminal equipment determines a first integrity protection data rate value according to the configuration information;

s203, the terminal device sends the first integrity protection data rate value to the network side device.

The network side device in this implementation may be a core network device, and may also be an access network device. If the network side equipment is core network equipment, the core network equipment sends integrity protection configuration information to the terminal equipment through the access network equipment; and if the network side equipment is the access network equipment, the access network equipment directly sends integrity protection configuration information to the terminal equipment.

The Integrity protection configuration information of this embodiment is terminal device Integrity Protection (IP) rate capability information that is configured in advance by a network side device, and the configuration information includes one or more Integrity protection data rate values. And the terminal equipment determines the integrity protection data rate capability value reported to the network, namely a first integrity protection data rate value according to the configuration information, and sends the first integrity protection data rate value to the network side equipment.

It should be noted that the first integrity protection data rate value reported by the terminal device may be the same as or different from the integrity protection data rate value actually supported by the terminal device itself. For example, the one or more integrity protection data rate values included in the network-side device pre-configuration information are discontinuous integrity protection data rate values, and these rate values are obtained by dividing the integrity protection data rate value feedback by the network, for example, the integrity protection data rate value may be from 0Kbps to 5Gps, and then the network may divide the range from 0Kbps to 5Gps, for example, into: 250Kbps, 500Kbps, 1Mbps, 5Mbps, 10Mbps, 20Mbps, 40Mbps, 60Mbps, 80Mbps, 100Mbps, 120Mbps, 140Mbps, 160Mbps, 180Mbps, 200Mbps, 250Mbps, 300Mbps, 400Mbps, 600Mbps, 800Mbps, 1Gbps, 2Gbps, 3Gbps, 4Gbps, 5 Gbps. The network expects the UE to select a value from the above values to report. For example, the value of the integrity protection data rate actually supported by a certain terminal device itself is 300Kbps, the value of the data rate is between 200Kbps and 500Kbps of the value of the integrity protection data rate in the configuration information, and the terminal device determines that the reported first value of the integrity protection data rate is 200Kbps instead of 300Kbps according to the configuration information. In addition, the value of the integrity protection data rate actually supported by the terminal device is 350Kbps, the value of the data rate is between 200Kbps and 500Kbps of the value of the integrity protection data rate in the configuration information, and the terminal device determines that the value of the reported first integrity protection data rate is also 200Kbps according to the configuration information, but not reports 350 Kbps. That is, the terminal device reports the integrity protection data rate capability value thereof based on the configuration information sent by the network side device in advance. The network side device obtains the user plane security policy, and determines whether to start user plane encryption protection and/or user plane integrity protection according to the user plane security policy, which is the prior art and is not described herein.

In the communication method provided by this embodiment, integrity protection configuration information including one or more integrity protection data rate values is sent to a terminal device through a network side device; the terminal equipment determines a first integrity protection data rate value according to the integrity protection configuration information, wherein the first integrity protection data rate value is one of integrity data rate values configured on the network side; and the terminal equipment sends the first integrity protection data rate value to the network side equipment. The communication process strengthens the network participation degree and improves the flexibility of network configuration.

On the basis of the above embodiments, the following four embodiments respectively show different types of integrity protection configuration information, and the terminal device executes corresponding steps according to the different types of integrity protection configuration information, and sends the self integrity protection data rate capability value to the network side device after determining the self integrity protection data rate capability value. The communication method provided by each embodiment is described in detail below with reference to the accompanying drawings.

Fig. 3 is a flowchart illustrating a communication method according to another embodiment of the present application. As shown in fig. 3, the communication method 300 provided in this embodiment includes the following steps:

s301, the network side equipment sends integrity protection configuration information to the terminal equipment; the configuration information includes a list of integrity protected data rate values;

s302, the terminal equipment acquires one or more integrity protection data rate values according to the integrity protection data rate value list;

s303, the terminal equipment determines a first integrity protection data rate value according to the acquired one or more integrity protection data rate values;

s304, the terminal device sends the first integrity protection data rate value to the network side device.

The integrity protection configuration information of this embodiment includes a list of integrity-protected data rate values including one or more integrity-protected data rate values. Illustratively, the list of data rate values includes the following integrity-protected data rate values: 250Kbps, 500Kbps, 1Mbps, 5Mbps, 10Mbps, 20Mbps, 40Mbps, 60Mbps, 80Mbps, 100Mbps, 120Mbps, 140Mbps, 160Mbps, 180Mbps, 200Mbps, 250Mbps, 300Mbps, 400Mbps, 600Mbps, 800Mbps, 1Gbps, 2Gbps, 3Gbps, 4Gbps, 5 Gbps. And the terminal equipment acquires one or more integrity protection data rate values according to the data rate value list.

The terminal equipment determines the position of the integrity protection data rate value supported by the terminal equipment in the data rate value list according to the acquired one or more integrity protection data rate values and the integrity protection data rate value supported by the terminal equipment, and selects a first integrity protection data rate value reported from the data rate value list. Assuming that the integrity protection data rate value supported by the terminal device is C, the one or more integrity protection data rate values obtained by the terminal device include two adjacent data rate values a and B, and if C is greater than or equal to a and less than B, the terminal device selects the first reported integrity protection data rate value as a. As can be seen, the first integrity protection data rate value reported by the terminal device is less than or equal to the integrity protection data rate value supported by the terminal device. For example, the integrity protection data rate value supported by the terminal device is 500Mbps, 500Mbps is between 400Mbps and 600Mbps, and the reported first integrity protection data rate value is 400 Mbps; the integrity protection data rate value supported by the terminal equipment is 250Mbps, and the reported first integrity protection data rate value is also 250 Mbps.

In a possible implementation manner, the data rate value list of this embodiment further includes a number corresponding to each integrity protection data rate value. Correspondingly, after acquiring one or more integrity protection data rate values and numbers corresponding to the integrity protection data rate values, the terminal device determines a first number corresponding to a first integrity protection data rate value selected and reported from the data rate value list according to the position of the integrity protection data rate value supported by the terminal device in the data rate value list, sends the first number to the network side device, and the network side device determines the first integrity protection data rate value corresponding to the first number by inquiring the preconfigured data rate value list. The above-mentioned sending mode of the terminal equipment reduces the occupancy rate of network resources.

In the communication method provided by this embodiment, the integrity protection configuration information sent by the network side device to the terminal device includes an integrity-protected data rate value list, where the data rate value list includes one or more integrity-protected data rate values; and the terminal equipment determines a first integrity protection data rate value according to the obtained one or more integrity protection data rate values and sends the first integrity protection data rate value to the network side equipment. The communication process strengthens the network participation degree and improves the flexibility of network configuration.

The terminal device obtains all integrity-protected data rate values of the integrity-protected data rate value list according to the configuration information of this embodiment. The configuration information provided by the embodiment is limited to the plurality of integrity-protected data rate values in the integrity-protected data rate value list being distributed at equal intervals.

Illustratively, the integrity protection configuration information includes a maximum value of 900Mbps, a minimum value of 300Mbps, and a step size of 100Mbps for the integrity protection data rate, then the following integrity protection data rate values are included in the integrity protection data rate value list: 300Mbps, 400Mbps, 500Mbps, 600Mbps, 700Mbps, 800Mbps, 100Mbps, 900 Mbps.

In the communication method provided in this embodiment, the integrity protection configuration information sent by the network side device to the terminal device includes a minimum value and a step length of the integrity protection data rate, the terminal device obtains one or more integrity protection data rate values according to the minimum value and the step length of the integrity protection data rate, determines a first integrity protection data rate value according to the obtained one or more integrity protection data rate values, and sends the first integrity protection data rate value to the network side device. The communication process strengthens the network participation degree and improves the flexibility of network configuration.

Fig. 6 is a flowchart illustrating a communication method according to still another embodiment of the present application. As shown in fig. 6, the communication method 600 provided in this embodiment includes the following steps:

s601, the network side equipment sends integrity protection configuration information to the terminal equipment; the configuration information includes group information of integrity protection data rate values; group information indicating one or more integrity-protected data rate groups, one said integrity-protected data rate group containing one or more integrity-protected data rate values;

s602, the terminal equipment acquires one or more integrity protection data rate values according to the group information;

s603, the terminal equipment determines a first integrity protection data rate value according to the obtained one or more integrity protection data rate values;

s604, the terminal device sends the first integrity protection data rate value to the network side device.

The integrity protection configuration information provided in this embodiment includes group information of integrity protection data rate values, where the group information is used to indicate one or more integrity protection data rate groups, and one integrity protection data rate group includes one or more integrity protection data rate values. Illustratively, the integrity protection configuration information includes the following 4 integrity protection data rate groups, and an integrity protection data rate value corresponding to each integrity protection data rate group:

a first group: 250Kbps, 500Kbps, 1 Mbps;

second group: 5Mbps, 10Mbps, 20Mbps, 40Mbps, 60Mbps, 80Mbps, 100 Mbps;

third group: 120Mbps, 140Mbps, 160Mbps, 180Mbps, 200Mbps, 250Mbps, 300Mbps, 400Mbps, 600Mbps, 800 Mbps;

and a fourth group: 1Gbps, 2Gbps, 3Gbps, 4Gbps, 5 Gbps.

And the terminal equipment acquires one or more integrity protection data rate values according to the group information of the integrity protection data rate values. The terminal equipment determines the position of the integrity protection data rate value supported by the terminal equipment in a data rate value list consisting of a plurality of integrity protection data rate values according to the acquired one or more integrity protection data rate values and the integrity protection data rate value supported by the terminal equipment, and selects a first integrity data rate value reported from the data rate value list. And the first integrity protection data rate value is less than or equal to the integrity protection data rate value supported by the terminal equipment.

In a possible implementation manner, the terminal device obtains a packet number and an intra-group number corresponding to the first integrity protection data rate value according to the group information; and the terminal equipment sends the packet number and the intra-group number corresponding to the first integrity protection data rate value to the network side equipment. The network side equipment determines a packet number and a first integrity protection data rate value corresponding to the number in the packet by inquiring the pre-configured group information. The above-mentioned sending mode of the terminal equipment reduces the occupancy rate of network resources.

In the communication method provided by this embodiment, the integrity protection configuration information sent by the network side device to the terminal device includes group information of integrity protection data rate values, and one or more integrity protection data rate values are obtained through the group information; and the terminal equipment determines a first integrity protection data rate value according to the obtained one or more integrity protection data rate values and sends the first integrity protection data rate value to the network side equipment. The communication process strengthens the network participation degree and improves the flexibility of network configuration.

At present, the possible integrity protection data rate values are all clearly defined by integrity protection configuration information prestored by network side equipment, the configuration information is relatively fixed, and the flexibility of the configuration information is relatively low. On the one hand, the extended updating of the configuration information is not facilitated, for example, the integrity protection data rate capability of the terminal device is enhanced in the future, and smaller integrity protection data rate values such as 250Kbps and 500Kbps will not be used, but the indication space is still occupied for the terminal device reporting. For example, 5 bits may be used to indicate 32 possible integrity protection data rate values, which will still occupy two of the 32 possible values if the terminal device is no longer reporting 250Kbps or 500 Kbps; for another example, in most of the time in practical applications, few terminal devices have the integrity protection data rate capability to support data rate values above 1Gbps, or, in a terminal device that does not support data rate values above 1Gbps for a certain period of time in a practical network, 1Gbps and integrity protection data rate values above 1Gbps will occupy more than 32 possible values. On the other hand, the division of the integrity protection data rate value in the configuration information is relatively coarse, for example, 1Gbps to 2Gbps have a 1G span value, and the division mode is not favorable for truly reflecting and distinguishing the integrity protection data rate capability of each terminal device.

Based on the above problems, the communication method provided in this embodiment shows an update process of the integrity protection configuration information by the network side device, and deletes unnecessary integrity protection data rate values through the update process, or increases the number of integrity protection data rate values within a certain data rate value range, thereby implementing flexible configuration of the integrity protection data rate values, and facilitating the network side device to distinguish actual capabilities of each terminal device according to the updated configuration information. The communication method provided in the present embodiment will be described in detail below with reference to fig. 7.

Fig. 7 is a flowchart illustrating a communication method according to still another embodiment of the present application. As shown in fig. 7, the communication method 700 provided in this embodiment includes the following steps:

s701, a network side device receives a first integrity protection data rate value sent by a plurality of terminal devices;

s702, updating configuration information by the network side equipment according to a first integrity protection data rate value sent by the plurality of terminal equipment;

and S703, the network side equipment sends the update information of the configuration information to the plurality of terminal equipment.

In this embodiment, the updating of the configuration information by the network side device includes: an addition, and/or a deletion, of an integrity protection data rate value in the configuration information.

In a possible implementation manner, the network side device counts the situation of the integrity protection data rate capability of the terminal device in the current network according to the first integrity protection data rate values sent by the plurality of terminal devices within the preset time period, if the integrity protection data rate values received by the network side device within the preset time period are concentrated within a certain data rate value range, it is indicated that there are more terminal devices within the data rate value range, in order to further distinguish the integrity protection data rate capability of each terminal device, the network side device may subdivide the data rate value range, increase the number of the integrity protection data rate values within the data rate value range, and improve the granularity for dividing the integrity protection data rate values. Illustratively, if the integrity protection data rate values received by the network side device in the preset time period are concentrated in 300Mbps to 400Mbps, the network side device may correspondingly increase the number of the integrity protection data rate values of 300Mbps to 400Mbps in the configuration information, such as 300Mbps, 320Mbps, 340Mbps, 360Mbps, 380Mbps, and 400 Mbps.

In another possible implementation manner, the network side device may calculate an integrity protection data rate capability of the terminal device in the current network according to first integrity protection data rate values sent by a plurality of terminal devices within a preset time period, and if the first integrity protection data rate value sent by any terminal device is never received by the network side device within a certain data rate value range within the preset time period, it indicates that there is no terminal device within the data rate value range in the current network, and the network side device may delete the integrity protection data rate value within the data rate value range. For example, if the network side device never receives the integrity protection data rate value at 3Gbps to 4Gbps in the preset time period, the network side device may correspondingly delete the integrity protection data rate value at 3Gbps to 4Gbps in the configuration information.

The network side equipment updates the integrity protection configuration information according to a first integrity protection data rate value sent by the plurality of terminal equipment within a preset time period, and then sends the update information of the configuration information to the plurality of terminal equipment. In a possible implementation manner, the network side device sends update information of the configuration information to a plurality of terminal devices connected with the network side device in a broadcast manner; in another possible implementation manner, the network side device sends the update information of the configuration information to a specific terminal device through a dedicated signaling, for example, the network side device issues the update information of the configuration information in a session update instruction.

It should be noted that, after receiving the update information of the configuration information sent by the network side device, the terminal device that has reported the first integrity protection data rate value may continue to use the integrity protection data rate capability reported before. Optionally, the terminal device that has reported the first integrity protection data rate value may also re-determine the first integrity protection data rate value according to the update information of the configuration information, and report the updated first integrity protection data rate value.

According to the communication method provided by the embodiment of the application, based on the first integrity protection data rate values sent by the plurality of terminal devices within the preset time period, the network side device updates the integrity protection configuration information according to the first integrity protection data rate values sent by the plurality of terminal devices, and sends the update information of the configuration information to the plurality of terminal devices, so that the plurality of terminal devices report the integrity protection data rate capability of the plurality of terminal devices according to the update information of the configuration information. The process ensures that the integrity protection data rate value reported by the terminal equipment is more accurate, and is more beneficial to the actual application and the future expansion of the integrity protection configuration.

On the basis of the foregoing embodiments, the configuration information of this embodiment further includes integrity protection data rate thresholds corresponding to different features. The terminal equipment judges whether to initiate a certain session service according to the integrity protection data rate threshold values corresponding to different characteristics, so that an unnecessary session establishment flow is avoided, and the occupation of network resources is reduced. See in particular the examples below.

Fig. 8 is a flowchart illustrating a communication method according to still another embodiment of the present application. As shown in fig. 8, the communication method 800 provided in this embodiment includes the following steps:

s801, a network side device sends integrity protection configuration information to a terminal device, wherein the configuration information comprises one or more integrity protection data rate values and integrity protection data rate thresholds corresponding to different characteristics;

s802, the terminal equipment judges whether to initiate a session establishment request according to the integrity protection data rate threshold values corresponding to different characteristics in the configuration information.

Specifically, the characteristics included in the configuration information of this embodiment may be a service type, a UE type, UE capability information, or other possible characteristics, and the present application is not limited in particular.

In a possible implementation manner, the configuration information of the network side device includes integrity protection data rate thresholds corresponding to different service types, where the service types include a video service type, a voice service type, a desktop sharing service type, and the like. Correspondingly, the terminal device may determine, according to the session request and the configuration information corresponding to the service type initiated by the user, an integrity protection data rate threshold corresponding to the service type and a first integrity protection data rate value reported by the terminal device. It is understood that the integrity protection data rate thresholds for different traffic types may be the same or different. The realization mode is that the configuration information is refined from the service type dimension, and whether to initiate the session establishment request of different service types can be judged at the terminal equipment side.

Illustratively, after acquiring a session request corresponding to a first service type initiated by a user, a terminal device determines whether to initiate a session establishment request to a network-side device according to integrity protection configuration information sent by the network-side device. Specifically, the terminal device obtains an integrity protection data rate threshold corresponding to a first service type according to integrity protection data rate thresholds corresponding to different service types in the configuration information; determining self-supported integrity protection data rate capability; comparing the integrity protection data rate capability value supported by the self with the integrity protection data rate threshold value corresponding to the first service type: if the integrity protection data rate capability value supported by the terminal equipment is larger than or equal to the integrity protection data rate threshold value corresponding to the first service type, the terminal equipment initiates a session establishment request to network side equipment; and if the integrity protection data rate capability value supported by the terminal equipment is smaller than the integrity protection data rate threshold value corresponding to the first service type, the terminal equipment refuses the session request corresponding to the first service type initiated by the user.

In a possible implementation manner, the configuration information of the network side device includes integrity protection data rate thresholds corresponding to different UE types. Correspondingly, the terminal equipment determines an integrity protection data rate threshold corresponding to the type of the terminal equipment and a first integrity protection data rate value reported by the terminal equipment according to a session request initiated by a user and configuration information. It is to be understood that the integrity protection data rate thresholds for different UE types may be the same or different. The realization mode is that the configuration information is refined from the UE type dimension, and whether to initiate the session establishment requests of different UE types can be judged at the terminal equipment side.

In a possible implementation manner, the configuration information of the network side device includes integrity protection data rate thresholds corresponding to different UE capabilities. Correspondingly, the terminal equipment determines an integrity protection data rate threshold corresponding to the terminal equipment capability and a first integrity protection data rate value reported by the terminal equipment according to a session request initiated by a user and configuration information. It is to be understood that the integrity protection data rate thresholds for different UE capabilities may be the same or different. The realization mode is that the configuration information is refined from the UE capability dimension, and whether a session establishment request with different UE capabilities is initiated can be judged at the terminal equipment side.

Optionally, if the terminal device initiates a session establishment request to the network side device, the session establishment request includes a first integrity protection data rate value of the terminal device, where the first integrity protection data rate value is determined by the terminal device according to an integrity protection data rate capability value supported by the terminal device and the configuration information received from the network device.

Based on the foregoing implementation manners, in the communication method provided in this embodiment, the network side device sends integrity protection configuration information including one or more integrity protection data rate values and integrity protection data rate thresholds corresponding to different features to the terminal device, and the terminal device determines whether to initiate a session establishment request according to the integrity protection data rate thresholds corresponding to different features in the configuration information. The above process avoids unnecessary session establishment flow and releases network resources occupied by the session establishment flow.
