[0040] The embodiments of the present disclosure provide an information processing method, a terminal, a communication system, and a storage medium.

[0041] In a first aspect, an embodiment of the present disclosure proposes an information processing method, including: a network device sends first information, wherein the first information is used by a terminal to determine a key-related operation.

[0042] In the above embodiment, the first information may be sent to the terminal via the network device, so that the terminal can accurately determine the key-related operation, thereby facilitating improved secure communication between the network device and the terminal.

[0043] In conjunction with some embodiments of the first aspect, in some embodiments, the key-related operation includes at least one of the following:

[0044] Whether to update the key;

[0045] Generate a key.

[0046] In the above embodiment, the terminal can accurately determine whether to update the key through the first information, and / or the terminal can accurately generate the key through the first information, thereby facilitating improving the security between the network device and the terminal.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, the first information is used by the terminal to determine a key-related operation, including at least one of the following:

[0048] The first information is used by the terminal to determine key-related operations when performing mobility operations;

[0049] The first information is used by the terminal to determine a key-related operation after performing a mobility operation.

[0050] In the above embodiment, the terminal can accurately determine whether the key needs to be updated or the generated key needs to be accurately determined during mobility and / or after mobility operations, so that the terminal can regenerate the key in a mobile scenario without reusing the previous key; this can improve the security between the network device and the terminal in a mobile scenario.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the key is a key corresponding to a secondary node (SN).

[0052] In the above embodiment, the security key of the secondary node can be accurately determined.

[0053] In conjunction with some embodiments of the first aspect, in some embodiments, the mobility operation includes at least one of the following:

[0054] Conditional Handover (CHO);

[0061] In combination with some embodiments of the first aspect, in some embodiments, sending the first information includes: sending Radio Resource Control (RRC) signaling, where the RRC signaling carries the first information.

[0062] In the above embodiment, the first information may be sent by multiplexing RRC signaling, thereby improving the utilization rate of RRC signaling and saving signaling overhead.

[0063] In combination with some embodiments of the first aspect, in some embodiments, the first information includes: configuration information, wherein the configuration information is used to configure the first identification set; wherein the first identification set is used to identify a set of count values, and the count value is the value of the counter; the value of the counter is used to generate the key corresponding to the SN.

[0064] In the above embodiment, the first identification set used to generate the key can be sent to the terminal, so as to help the terminal determine whether the first identification set of the SN to be switched to has changed from the current first identification set, thereby determining whether to update the key and / or accurately generate the key based on the first identification set.

[0065] In conjunction with some embodiments of the first aspect, in some embodiments, the configuration information includes at least one of the following:

[0066] An index (Index), and a first identifier set corresponding to the index;

[0067] An index, an SN identifier corresponding to the index, and a first identifier set; the SN identifier is used to identify a candidate SN;

[0069] The above embodiments provide multiple ways for network devices to configure a first identification set for a terminal, facilitating adaptation to a wider range of application scenarios. Furthermore, each first identification set can correspond to an index, and each index corresponds to a candidate SN. This allows the terminal to be configured with a first identification set for at least one candidate SN. This facilitates the terminal's ability to determine whether the first identification set of the current SN has changed.

In this way, the conditional reconfiguration configuration can have two functions of indicating the first identification set and the configuration for mobility operations. There is no need for additional signaling to send the first identification set, thereby reducing signaling overhead.

[0074] Furthermore, if each conditional reconfiguration configuration carries first information including a first identifier set, a corresponding first identifier set can be configured for each conditional reconfiguration configuration.

In this way, the conditional reconfiguration configurations belonging to the same candidate SN can be configured with the same first identification set, and there is no need to configure the first identification set in each conditional reconfiguration configuration, thereby saving configuration resources.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0222] In some embodiments, dual connectivity technologies include the following:

[0223] The first is Multi-Radio Dual Connectivity (MR-DC).

[0224] MR-DC is a generalized Universal Mobile Telecommunication System (UMTS) Intra-E-UTRA dual connectivity. In this system, a UE can utilize radio resources provided by two different resource scheduling units located on two different Next Generation Radio Access Network (NG-RAN) nodes, connected via a non-ideal backhaul: one providing New Radio (NR) access and the other providing E-UTRA or NR access. The base station of the primary cell can be a master node (MN), and the base station of the secondary cell can be a secondary node (SN). The master and secondary nodes are connected via a network interface, with at least one master node connected to the core network.

[0225] The second type is MR-DC based on the Evolved Packet Core (EPC).

[0226] As shown in Figure 1B, it is a schematic diagram of the architecture of Evolved Universal Terrestrial Radio Access Network (E-UTRA-NR) Dual Connectivity (EN-DC). E-UTRAN supports MR-DC through E-UTRA-NR DC (EN-DC), where the UE is connected to a base station eNB acting as a master node (MN) and a base station en-gNB acting as a secondary node (SN). The base station eNB is connected to the core network EPC through the S1 interface and to the base station en-gNB through the X2 interface. The base station en-gNB can also be connected to the core network EPC through the S1-U interface and to other base station en-gNBs through the X2-U interface. The core network equipment of the EPC may include: Mobility Management Entity (MME) and / or Service-Gateway (S-GW).

[0227] The third type is the MR-DC of the fifth-generation mobile communication core network (5th Generation Core, 5GC).

[0228] 5GC supports the following dual connections:

[0229] 1) Dual connectivity of E-UTRA-NR and NGEN-DC.

[0230] The 5G radio access network (NG-RAN) supports NG-RAN E-UTRA-NR dual connectivity (NGEN-DC), in which the UE is connected to the ng-eNB as the master node (MN) and to a gNB as the secondary node (SN). The base station (ng-eNB) is connected to the 5GC, and the base station (gNB) is connected to the base station ng-eNB through the Xn interface.

[0231] 2) Dual connectivity for NR-E-UTRA.

[0232] NG-RAN supports NR-E-UTRA Dual Connectivity (NE-DC), where the UE is connected to a gNB acting as a master node (MN) and an ng-eNB acting as a secondary node (SN). The gNB is connected to the 5GC, and the ng-eNB is connected to the gNB via the Xn interface.

[0233] 3) NR-NR dual connectivity.

[0234] Figure 1C shows an NR-DC architecture. NG-RAN supports NR-NR dual connectivity (NR-DC), where the UE is connected to a gNB acting as a master node (MN) and another gNB acting as a secondary node (SN). The master gNB is connected to the 5GC via the NG interface, and the two gNBs are connected via the Xn interface. The secondary gNB can also be connected to the 5GC via the NG-U interface. In addition, NR-DC can also be used for UEs to access a single gNB, which acts as both a master node (MN) and a secondary node (SN), and is configured with a primary cell group (MCG) and a secondary cell group (SCG).

[0235] In some embodiments, as shown in Figure 1D, under dual connectivity, the UE can access two cell groups, namely the main cell group (MCG) and the secondary cell group (SCG). Under the MCG, there may be many cells (Cell), one of which is used to initiate initial access, and this cell is called (PCell). As the name suggests, PCell is the most "main" cell in the MCG. The PCell under the MCG and the SCell under the MCG are combined through CA. The main cell in the MCG is the PCell, and the secondary cell is the SCell; the main and secondary cells in the SCG are the PSCell, and the secondary cell is the SCell. Because many signalings are only sent on the PCell and PSCell, for the convenience of description, the protocol also defines a concept of special main cell (sPCell) and PSCell, collectively referred to as sPCell.

[0236] Subsequent CHO / CPAC may be referred to as cell group (MCG / SCG) selective activation. Optionally, subsequent CPAC includes at least one of subsequent CPC and subsequent CPA.

[0237] In some embodiments, during conditional handover (CHO) and conditional PSCell change (CPC) / conditional PSCell addition (CPA), the terminal must release the CHO / CPC / CPA configuration upon completing random access to the target PCell / PSCell. Therefore, if the network does not reconfigure and reinitialize CHO / CPC / CPA, the terminal will not have the opportunity to subsequently perform CHO / CPC / CPA. This will increase the latency of handover or SCG change and increase signaling overhead, especially in FR2 scenarios with frequent CG changes.

[0238] Therefore, subsequent CHO / CPA is proposed. Subsequent CHO / CPA can also be called cell / cell group selective activation. After triggering the change or addition of a cell group or cell, the terminal does not delete the conditional reconfiguration configuration (CHO and / or CPAC configuration). In the absence of RRC reconfiguration or reinitialization of the conditional reconfiguration configuration, the original CHO / CPAC configuration can continue to be used for subsequent CHO / CPAC. Supporting subsequent CHO / CPAC can effectively reduce signaling overhead and reduce the interruption time of cell group changes (or SPCell) changes.

[0239] The configuration of a subsequent CHO / CPAC includes but is not limited to at least one of the following: a configuration identifier, an execution condition, and a configuration of a corresponding candidate target cell (or cell group).

[0240] The network side can configure multiple Subsequent CHO / CPAC configurations and reference configurations for the UE at the same time.

[0241] Optionally, the configuration identifier is an identifier (ID) indicating a related configuration.

[0242] Optionally, the execution condition is triggering a mobility operation (triggering CHO, CPAC, a condition that the UE needs to meet).

[0243] Optionally, the configuration of the corresponding candidate target cell (or cell group) is a candidate configuration corresponding to the target cell accessed when the UE triggers a mobility operation, and this configuration may be represented by RRC Reconfiguration.

[0244] The reference configuration is the reference configuration corresponding to the candidate target configuration. The candidate target configuration is an incremental configuration of the reference configuration. A complete configuration can be generated based on the candidate target configuration and the reference configuration. This configuration can be represented by RRC reconfiguration. The UE applies the complete configuration when performing CHO / CPAC. The reference configuration can be a specific configuration generated by the network or the current configuration of the UE. The reference configuration is only required for subsequent CHO / CPAC configurations.

[0245] In some embodiments, the CHO and CPAC configurations do not include a reference configuration, but only include a configuration identifier, execution conditions, and the configuration of the corresponding candidate target cell (or cell group). The target cell accessed when the UE triggers a mobility operation directly applies the configuration of the candidate target cell (or cell group).

[0246] In subsequent CHO / CPAC, the network can provide candidate configurations to the UE. These candidate configurations can be applied multiple times without re-provisioning. That is, in subsequent CHO / CPAC, after applying the new cell group configuration to access a new cell, the UE will not delete the original subsequent CHO / CPAC configuration.

[0247] For example, for procedural CPAC, that is, selective activation of SCG, subsequent CPAC can be continued after SCG and / or PSCell changes or additions occur without RRC reconfiguration.

[0248] In some embodiments, as shown in Figure 1E, the RRCReconfiguration message is a command to modify the RRC connection. It can transmit information for measurement configuration, mobility control, radio resource configuration (including RBs, MAC primary configuration and physical channel configuration), and security configuration.

[0249] In some embodiments, conditional reconfiguration is used to configure candidate target SpCells and / or execution conditions for at least one of conditional switching, conditional PSCell addition, or conditional PSCell change.

[0250] Optionally, the Conditional Reconfiguration information element (ConditionalReconfiguration information element) is used to add, modify, and publish the configuration of the conditional reconfiguration.

[0251] Optionally, as shown in FIG1F , a conditional reconfiguration information unit implementation method is provided.

[0252] In some embodiments, the mobility configuration of the conditional reset may include, but is not limited to, one or more of the following information:

[0253] The conditional reconfiguration add-modify table (condReconfigToAddModList) is used to add one or more conditional reconfigurations and / or modify one or more existing conditional reconfigurations;

[0254] The conditional reconfiguration deletion table (condReconfigToRemoveList) is used to delete one or more conditional reconfiguration mobility configurations.

[0255] Optionally, as shown in FIG1G , an implementation of a conditional reconfiguration addition and / or modification information element (CondReconfigToAddModList information element) is provided. Optionally, the information element includes a conditional reconfiguration list to be added or modified, and for each entry, a conditional reconfiguration ID and an associated conditional execution condition or conditional execution condition SCG (condExecutionCond / condExecutionCondSCG) and conditional reconfiguration.

[0256] In some embodiments, IE SK-Counter is a counter used for the initial configuration of SN security for NR-DC and NE-DC, and is used during RRC resume or RRC reconfiguration based on the current or newly derived base station root key (K gNB ) Update SK gNB or SK eNB Alternatively, the implementation of IE SK-Counter may be as shown in FIG1H .

[0257] In some embodiments, the SN counter maintenance may be at least one of the following:

[0258] The MN shall maintain a 16-bit counter in its AS security context, such as the SN counter. Calculate K SN SN counter is used when

[0259] The MN maintains the value of the counter as the security context between the UE and the MN during the duration of the current 5G. SN There is no need to maintain the SN counter afterwards, because when the UE needs to calculate a new K SN When K is reached, the MN provides the UE with the current SN counter value. SNThat is, the UE assumes that the MN provides a new SN counter every time and does not need to verify the freshness of the SN counter (Note: an attacker cannot modify the SN counter over the air and force the reuse of the same SN counter value. The reason is that the SN counter is passed over the RRC connection between the MN and the UE, and the connection is integrity protected and prevented from replay).

[0260] When a new AS root key K is established in the associated 5G AS security context NG-RAN When the MN calculates the SN counter, it shall set the SN counter to "0". SN After that, the MN sets the SN counter to “1” and for each additional calculated K SN Monotonically increasing. The value of SN counter “0” is used to calculate the first K SN .

[0261] If the MN decides to release the connection offloaded to the SN and later decides to restart offloading to the same SN, the value of the SN counter will keep increasing, thus maintaining the calculated K SN It's new.

[0262] Before the SN counter wraps around, the MN will refresh the 5G root key as the security context associated with the SN counter. The root key refresh can be done using intra-cell handover. When the root key is refreshed, the SN counter is reset to "0".

[0263] In some embodiments, the derivation of the key may include at least one of:

[0264] The UE and MN will derive the SN's security key KSN.

[0265] SN can be ng-eNB or gNB, KS from SN and UE N SN RRC and UP keys are derived from

[0266] Once you have SN After all SN RRC and UP keys are exported, SN and UE can delete K SN .

[0267] In some embodiments, the dual connectivity K SN The derivation can be as follows:

[0268] This input string is used when the MN and UE derive the KSN during dual connectivity. The following input parameters shall be used:

[0269] FC=0x79;

[0270] P0 = value of SN counter in the form of non-negative integer;

[0271] L0 = length of the value of the SN counter (eg, 0x00 0x02).

[0272] When the MN is an ng-eNB, the input key should be KeNB; when the MN is a gNB, the input key should be KgNB.

[0273] In some embodiments, security issues of subsequent CPAC:

[0274] When updating the SN, the security key is generated by the MN. SN , sent to SN via Xn-C. In order to generate K SN MN is associated with a counter called SK-Counter. K is generated based on the security key of MN and SK-Counter. SN The MN sends the SK-Counter value to the terminal through RRCR configuration. Optionally, the security of the SN depends only on the SK-Counter and the MN's key.

[0275] For subsequent CPCs, if the existing process is followed, the SK-Counter stored in the CPC configuration will continue to be used. Therefore, for multiple subsequent CPCs on the same candidate PSCell, if the same SK-Counter stored in the CPC configuration is used, the same security key will be generated. This will lead to the security key reuse issue (i.e., using the same security key and Packet Data Convergence Protocol (PDCP) counter value to encrypt different data packets, which is not allowed).

[0276] Optionally, in response to the above security issues, the security issues of the following scenarios are clarified:

[0277] Question: RAN2 would like to know whether SA3 considers the existing handling of SK-Counter / S-KgNB in ​​the above scenario acceptable, i.e. using the same SK-counter / S-KgNB before connecting to SN# and after connecting to SN#1.

[0278] A: No, this is not acceptable from a security perspective.

[0279] Q: If SA3 considers the existing handling of SK-Counter / S-KgNB in ​​the above scenario unacceptable, RAN2 kindly requests SA3 to provide a solution.

[0280] A: You cannot use the same S-KgNB. SA3 will specify an additional sub-clause for security of selective SCG activation.

[0281] Optionally, it is clarified that the UE sends an SN change, and the same SK-Counter / S-KgNB cannot be used before and after the SN change. A solution to the security problem is also proposed, such as the following solution details triggered by security:

[0282] Step 1: For each SN, the MN provides the UE with multiple SN counter values; the UE stores the CPC configuration together with the SN counter values.

[0283] Step 2: UE uses K gNB and the unused SN calculator value provided in advance by MN to derive K SN When performing SN conversion, the UE will change the value of the SN counter.

[0284] In some embodiments, the following problems exist:

[0285] The UE generates a new K according to the SN counter pre-configured by the MN after the SN conversion occurs. SN To avoid the reuse of SN keys. However, since CPC configuration is configured for each candidate cell, the CPC configuration information does not carry the candidate SN information. The UE cannot know the candidate SN corresponding to each candidate PSCell / SCG. Therefore, the UE does not know whether the SN has changed when executing Subsequent CPC.

[0286] Since CPC and subsequent CPC are triggered by the UE based on the conditions pre-configured by the network side, the network side cannot know when the UE will trigger the subsequent CPC, and thus cannot directly indicate whether the UE needs to update K when the next CPC occurs. SN .

[0287] Therefore, in order to solve the above problems, the present disclosure provides an embodiment for indicating whether K needs to be updated in the subsequent CPC.
