At present, a network device allocates a terminal capability information identifier to a terminal device through NAS signaling.

Please refer to fig. 2, which shows a flowchart of a method for reporting terminal capability information according to an exemplary embodiment of the present disclosure, and this embodiment illustrates that the method is used in the terminal device 140 shown in fig. 1. The method comprises the following steps.

Step 201, receiving a notification message sent through a downlink channel, where the notification message carries a filtering information identifier of the filtering information.

In the RRC layer terminal capability query process, filtering information is introduced to reduce the data volume when the terminal device reports the terminal capability information, and the filtering information is used to indicate a filtering condition when the terminal device reports the terminal capability information. The filtering information includes a plurality of Filter parameters.

Optionally, the filtering information includes, but is not limited to, the following parameters: the method comprises the steps that whether an access technology list reported by an expected terminal device, a frequency band information list contained in a frequency band combination reported by the expected terminal device and the frequency band combination reported by the expected terminal device comprise a 'fall back' frequency band combination or not; expecting the maximum uplink and/or downlink carrier number in the capability information reported by the terminal equipment; the maximum merging bandwidth of the uplink and/or downlink single frequency bands in the frequency band combination reported by the terminal equipment is expected; expecting the maximum combined bandwidth of all uplink and/or downlink frequency bands in the frequency band combination reported by the terminal equipment; expecting whether the capability information reported by the terminal equipment contains the frequency band combination of the specific dual connection; expecting the terminal device to report some specific capability indications; parameters such as the maximum number of layers of Multiple-Input Multiple-Output (MIMO) on each carrier, which are reported by the terminal device, are expected. The parameters included in the filtering information are increasing, and more filtering information may be defined in the future. The present embodiment does not limit the number and types of parameters included in the filter information.

The encoding of the filtering information is different in LTE and NR, there is an intersection of a plurality of Filter parameters of the filtering information in LTE and a plurality of Filter parameters in NR, and there is at least one Filter parameter that is different.

The filtering information is used to instruct the terminal device to filter the terminal capability information so as to reduce the data size of the terminal capability information, for example, the terminal device may reduce the lengths of the arrays of the band list (english: band list), the band combination list (english: band combination list), the function set list (english: feature set list), and the function set list (english: feature set per cc list) of each carrier unit through the filtering information, so that the subsequent terminal device may report the filtered terminal capability information on an air interface, reduce the load of an air interface signaling, and facilitate the maintenance of a network side.

Therefore, in the embodiment of the present disclosure, a filtering information identifier is provided for the filtering information, and the filtering information identifier of the filtering information is used for uniquely identifying the filtering information.

Wherein the filtering information is information for filtering the terminal capability information.

Optionally, the filtering information identifier is an identifier of filtering information used for filtering the terminal capability information, which is carried in the terminal capability query message in the RRC layer.

And the network end equipment sends a notification message to the terminal equipment through a downlink channel, wherein the notification message carries a filtering information identifier of the filtering information.

The preset corresponding relation is obtained by distributing terminal capacity information marks for terminal capacity information obtained by filtering the terminal equipment according to the filtering information corresponding to the specific filtering information marks issued by the network through the network.

After receiving a notification message sent by a network end device through a downlink channel, a terminal device obtains a filtering information identifier carried in the notification message. And the terminal equipment acquires the terminal capacity information identifier corresponding to the filtering information identifier according to a pre-stored preset corresponding relation.

And step 203, reporting the terminal capability information identifier through an uplink channel.

And the terminal equipment reports the terminal capacity information identifier to the network terminal equipment through an uplink channel. Correspondingly, the network terminal equipment receives the terminal capability information identifier sent by the terminal equipment through the uplink channel.

Optionally, the Uplink Channel is a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH).

In summary, in this embodiment, a notification message sent through a downlink channel is received by a terminal device, where the notification message carries a filtering information identifier of the filtering information, and a terminal capability information identifier corresponding to the filtering information identifier is obtained according to a preset corresponding relationship, where the preset corresponding relationship in the terminal device includes a corresponding relationship between the filtering information identifier and the terminal capability information identifier, so as to avoid a situation that network resources are wasted due to improper terminal capability information reporting by the terminal device in the related art, so that the terminal device can report a proper terminal capability information identifier in multiple terminal capability information identifiers based on the preset corresponding relationship, and ensure accuracy of reporting the terminal capability information while reducing overhead of an air interface signaling.

Please refer to fig. 3, which shows a flowchart of a method for reporting terminal capability information according to an exemplary embodiment of the present disclosure, and this embodiment illustrates that the method is used in the terminal device 140 shown in fig. 1. The method comprises the following steps.

Step 301, the terminal device receives a notification message sent through a downlink channel, where the notification message carries a filtering information identifier of the filtering information.

And the network terminal equipment sends a notification message through the downlink channel terminal equipment, wherein the notification message carries the filtering information identifier of the filtering information. Correspondingly, the terminal equipment receives the notification message carrying the filtering information identifier. Wherein the filtering information is information for filtering the terminal capability information.

Optionally, the notification message includes one of NAS layer signaling, RRC layer signaling, and system message.

In a possible implementation manner, the network side device sends the notification message to the terminal device through NAS layer signaling, and correspondingly, the terminal device receives the notification message sent through NAS layer signaling.

In another possible implementation manner, the network device sends a terminal Capability query (english: UE Capability query) message to the terminal device through an RRC signaling, and correspondingly, the terminal device receives the terminal Capability query message sent through the RRC signaling.

In another possible implementation manner, the network device broadcasts a filtering information identifier, which is mainly applied by the terminal device currently in the RAN, in a system message, and correspondingly, the terminal device receives the system message, so that whether the reported terminal capability information identifier meets expectations of the network side or not can be known when the subsequent terminal device performs startup registration and Tracking Area Code (TAC)/registration Area update registration.

In another possible implementation manner, the network end device sends part or all of the filtering information used by the network and the corresponding filtering information identifier to the terminal device through signaling (access stratum signaling or non-access stratum signaling). For example, the signaling is a registration accept message.

The terminal capability information identity comprises an identity of a currently serving PLMN assignment. The terminal capability information identification is used to uniquely identify the filtering information in the currently serving PLMN.

The identifier assigned by the PLMN is also referred to as a terminal (radio) capability information identifier assigned by the PLMN.

Optionally, the PLMN-assigned identity comprises an identification number for uniquely identifying the filtered information within the PLMN.

Wherein the identity of the PLMN is contained in or associated with the identity assigned to the PLMN. I.e. the different PLMNs are distinguished by the identity of the included PLMN or the identity of the associated PLMN being identified by the filtering information.

Optionally, the terminal capability information identifier includes a manufacturer assigned identifier. The manufacturer-assigned identifier is also referred to as a manufacturer-assigned terminal (wireless) capability information identifier.

Optionally, when the filtering information identifier is delivered inside one PLMN, the filtering information identifier carried in the notification message includes an identifier and an identification number of the PLMN, or only includes an identification number for uniquely identifying the filtering information within the PLMN.

Optionally, whether the terminal device supports the filtering information identifier should be able to indicate to the network side device. When the terminal device supports the filtering information identifier, executing the step 302; and when the terminal equipment does not support the filtering information identification, ignoring the filtering information identification and responding to the notification message.

It should be noted that, the process of the terminal device ignoring the filtering information identifier and responding to the notification message may refer to relevant details in the foregoing embodiments, and details are not described here again.

Step 302, the terminal device determines whether the filtering information identifier carried in the notification message meets a preset condition.

The preset condition comprises that the filtering information identification is not stored in the terminal equipment or the filtering information identification is stored in the terminal equipment but is invalid.

Optionally, before the terminal device determines whether the filtering information identifier carried in the notification message meets the preset condition, a plurality of filtering information identifiers are stored in the terminal device.

3GPP mentions that different areas have different filtering information, and different time periods may have different filtering information, and because of network deployment and new frequency band application, the filtering information and the filtering information identifier may have a life cycle. After this feature of the life cycle is introduced, in one possible implementation, a timer is set for the filtering information and filtering information identification, and the timeout expires.

Optionally, when the notification message is received, the life cycle timer corresponding to the filtering information and the filtering information identifier is started; the life cycle timer is used for indicating that the filtering information and the filtering information mark are invalid after the preset time length is exceeded. The specific value of the preset duration is not limited in this embodiment.

The filtering information identification and the filtering information identification are optional, and the terminal capability information identification and the terminal wireless capability set corresponding to the filtering information have preset life cycles.

In one illustrative example, the predetermined life cycle is T. The terminal device receives the notification message carrying the filtering information identifier n1 at time T1, the filtering information identifier n1 and the corresponding filtering information are valid between time T1 and time T1+ T, and the filtering information identifier n1 and the corresponding filtering information are invalid after time T1+ T.

The terminal equipment judges whether the filtering information identification carried in the notification message meets a preset condition, and executes the step 303 when the filtering information identification meets the preset condition; when the filtering information identifier does not satisfy the preset condition, step 304 is executed.

If the terminal device determines that the filtering information identifier is not stored in the terminal device, or the filtering information identifier is stored in the terminal device but is invalid, executing step 303; if the terminal device determines that the filtering information identifier is stored in the terminal device and the filtering information identifier is valid, step 304 is executed.

And 303, when the filtering information identifier meets the preset condition, ignoring the filtering information identifier and responding to the notification message.

When the filtering information identifier meets the preset condition, the terminal device ignores the filtering information identifier and responds to the notification message, including but not limited to the following possible implementation manners:

in a possible implementation manner, the notification message is NAS layer signaling, and when the filtering information identifier satisfies a preset condition, the terminal device ignores the filtering information identifier and responds to the NAS layer signaling carrying the filtering information identifier.

In another possible implementation manner, the notification message is an RRC layer signaling, the notification message further carries filtering information, and when the filtering information identifier meets a preset condition, the terminal device ignores the filtering information identifier and obtains terminal capability information by filtering according to the filtering information; and the terminal equipment reports the terminal capability information through an uplink channel.

Step 304, the terminal device obtains a terminal capability information identifier corresponding to the filtering information identifier according to a preset corresponding relationship, where the preset corresponding relationship includes a corresponding relationship between the filtering information identifier and the terminal capability information identifier.

Optionally, when the filtering information identifier does not meet the preset condition, that is, the filtering information identifier is stored in the terminal device and the filtering information identifier is valid, the terminal device obtains the terminal capability information identifier corresponding to the filtering information identifier according to the preset corresponding relationship. The preset corresponding relation comprises a one-to-one corresponding relation between a plurality of filtering information identifications and a plurality of terminal capability information identifications.

Optionally, before the terminal device obtains the terminal capability information identifier corresponding to the filtering information identifier according to the preset corresponding relationship, the terminal device correspondingly stores the filtering information identifier and the terminal capability information identifier.

The terminal capability information identity comprises a PLMN assigned identity and optionally also a manufacturer assigned identity.

The preset corresponding relation comprises a one-to-one corresponding relation between the filtering information identification and the identification distributed by the PLMN. Optionally, the preset correspondence further includes a many-to-one correspondence between the filtering information identifier and the identifier assigned by the manufacturer.

Manufacturer assigned identification: the terminal capability information identification is distributed by a manufacturer of the terminal equipment, and the identification distributed by the manufacturer comprises two parts of information, wherein one part of information is the information of the manufacturer, and the other part of information represents the terminal capability information identification of one terminal wireless capability set of the manufacturer. The manufacturer assigned identification is used to uniquely identify the terminal wireless capability set under any PLMN.

PLMN assigned identity: if the terminal device or the serving network cannot apply the manufacturer-assigned identity assigned by the manufacturer, or the manufacturer-assigned identity assigned by the manufacturer cannot be recognized by the serving network, the serving network may assign different terminal capability information identities to different sets of terminal wireless capabilities acquired from the terminal device at different times. In this case, the PLMN-assigned identity received by the terminal device may be applied to the serving PLMN and the corresponding set of terminal wireless capabilities may be uniquely identified under the PLMN.

The terminal device stores a plurality of identifiers allocated to the most recently used PLMNs, the PLMNs when allocating the identifier allocated to each PLMN, and the local configuration of the terminal device. For example, the identifiers assigned to the multiple most recently used PLMNs are the identifiers assigned to the 16 most recently used PLMNs. The present embodiment does not limit the number of the terminal capability information identifiers stored in the terminal device.

And 305, the terminal equipment reports the terminal capacity information identifier through an uplink channel.

And the terminal equipment reports the terminal capacity information identification through an uplink channel. Correspondingly, the network terminal equipment receives the terminal capability information identifier sent by the terminal equipment through the uplink channel.

It should be noted that, the implementation manner of reporting the terminal capability information identifier by the terminal device through the uplink channel may refer to the relevant details in the foregoing embodiment, and details are not described here again.

In an illustrative example, if the terminal device does not support the filtering information identifier, when the terminal device receives the NAS layer signaling carrying the filtering information identifier, the terminal device ignores the filtering information identifier and responds to the NAS layer signaling carrying the filtering information identifier; when the terminal equipment receives an RRC layer signaling carrying the filtering information identification, the terminal equipment ignores the filtering information identification and obtains terminal capability information by filtering according to the filtering information; and the terminal equipment reports the terminal capability information through an uplink channel.

In another illustrative example, if the terminal device supports the filtering information identifier, when the terminal device receives the NAS layer signaling carrying the filtering information identifier and the filtering information identifier is not stored in the terminal device, or the filtering information identifier is stored but has failed, the terminal device ignores the filtering information identifier and responds to the NAS layer signaling carrying the filtering information identifier; when the terminal equipment receives an RRC layer signaling carrying a filtering information identifier, and the filtering information identifier is not stored in the terminal equipment, or the filtering information identifier is stored but is invalid, the terminal equipment ignores the filtering information identifier and obtains terminal capability information by filtering according to the filtering information; and the terminal equipment reports the terminal capability information through an uplink channel.

In another illustrative example, if the terminal device supports the filtering information identifier, when the terminal device receives an NAS layer signaling or an RRC layer signaling carrying the filtering information identifier and the filtering information identifier is still stored and valid in the terminal device, the terminal device obtains the terminal capability information identifier corresponding to the filtering information identifier according to a preset corresponding relationship, and reports the terminal capability information identifier through an uplink channel.

In the related art, the network side device sends NAS layer signaling for requesting the terminal capability information to the terminal device, the NAS layer signaling carries filtering information, and the terminal device filters the filtering information to obtain the terminal capability information. The above method has several problems as follows:

the currently defined filtering information of 3GPP has different codes under different Radio Access Types (RATs), and even if the filtering information is sent to the terminal device through NAS layer signaling, the terminal device is difficult to determine whether the filtering information is the same filtering information;

the filtering information of LTE and NR is actually a complex of a plurality of flags and lists, is very complex on ASN.1, and is not clear in standard definition;

the signaling of the NAS layer carries filtering information, and the filtering information can be represented only by a whole terminal Capability query (English: UE Capability inquiry) message;

the terminal equipment compares the whole bit stream or each IE, and the implementation may not be consistent necessarily;

the terminal capability query messages under different RATs are different, and if an Access Stratum (AS) is required to provide filtering information to the NAS layer, the network side device may be required to know terminal capability query message codes of different RATs. Further, since the NAS layer does not know whether the terminal capability information of the terminal device is obtained from the filtering information under LTE or the filtering information under NR, it may not be possible to transmit the appropriate filtering information to the terminal device at a time.

In the embodiment of the disclosure, a filtering information identifier is provided for filtering information, the filtering information identifier and a terminal capability information identifier are stored in a terminal device in advance in a corresponding manner, the terminal capability information identifier includes an identifier allocated by a manufacturer and an identifier allocated by a PLMN, when the terminal device receives a notification message carrying the filtering information identifier, the terminal capability information identifier corresponding to the filtering information identifier can be obtained according to a preset corresponding relationship, and the terminal capability information identifier is reported to a network terminal device, so that on one hand, the data volume carried by NAS layer signaling is less; on the other hand, interactive signaling between the RAN and the core network is less, and the core network does not need to know the specific coding of the filtering information of the RAN; on the other hand, the terminal device can more easily judge which terminal capability information identifier in the stored plurality of terminal capability information identifiers is expected by the network, so that the judgment standard of the terminal device is more clear.

Please refer to fig. 6, which shows a flowchart of a method for reporting terminal capability information according to an exemplary embodiment of the present disclosure, and this embodiment is illustrated by using the method in the mobile communication system provided in fig. 4 or fig. 5. The method comprises the following steps.

Step 601, the access network device sends the expected filtering information identifier and/or filtering information to the core network device.

The access network device informs the core network device of the expected filtering information identification and/or filtering information in advance.

Step 602, the core network device sends an access network message to the access network device, where the access network message is used to request to acquire the terminal capability information.

Optionally, the access network information carries filtering information and/or a filtering information identifier expected by the access network device.

Step 603, the access network device sends an access network message and a terminal capability query message to the terminal device.

Optionally, the access network message and/or the terminal capability query message carry a filtering information identifier and/or filtering information expected by the access network device.

Step 604, the terminal device reports the access network information and the terminal capability information to the access network device.

And the terminal equipment reports the terminal capability information and the filtering information to the access network equipment (if the terminal capability information and the filtering information are received).

Optionally, the access network message and/or the terminal capability information carries a terminal capability information identifier and a corresponding filtering information identifier.

The terminal capability information is also called terminal wireless capability information, and the terminal capability information identifier is also called a terminal wireless capability information identifier.

Step 605, the access network device reports the terminal capability information to the core network device.

Step 606, if the terminal device does not provide the terminal capability information identifier but provides the terminal capability information, the core network device provides the UCMF entity with the terminal capability information, the filtering information and the filtering information identifier.

The core network equipment judges whether the terminal equipment provides the terminal capability information identification, if the terminal equipment does not provide the terminal capability information identification but provides the terminal capability information, the filtering information and the filtering information identification are provided for the UCMF entity.

Step 607, the UCMF entity stores the terminal capability information and assigns the identifier assigned by the PLMN.

Optionally, the UCMF entity stores the filtering information and the filtering information identifier.

In step 608, the UCMF entity provides the identifier assigned by the PLMN to the core network device.

Step 609, the core network device provides the identifier of the PLMN allocation newly allocated by the UCMF entity to the terminal device through the core network message.

In the NR system, the core network message may be a Registration Accept (Registration Accept) message or a UE Configuration Update Command (UE Configuration Update Command) message.

In the LTE system, the core network message may be an Attach Accept (Attach Accept) message or a Tracking Area Update Accept (Tracking Area Update Accept) message.

Step 610, the terminal device sends a feedback message to the core network device through the core network message, where the feedback message is used to indicate that the identifier of the PLMN allocation newly allocated by the UCMF entity is successfully received.

In the NR system, the feedback message may be a Registration Complete (english: Registration Complete) message or a terminal device Configuration Update Complete (english: UE Configuration Update Complete) message.

In the LTE system, the feedback message may be an Attach Complete (Attach Complete) message or a Tracking Area Complete (Tracking Area Update Complete) message.

Step 611, the terminal device stores the identifier allocated by the UCMF entity to the PLMN, the filtering information, and the filtering information identifier.

Step 612, the core network device sends a notification message to the access network device, where the notification message is used to indicate that the UCMF entity has allocated a new identifier allocated by the PLMN to the terminal.

In summary, if the filtering information identifier stored in the terminal device is not approved by the network end device or the terminal device does not store the filtering information identifier, the embodiment further allocates the filtering information identifier to the terminal device, and simultaneously stores the preset corresponding relationship between the filtering information identifier and the terminal capability information identifier in both the network and the terminal device, thereby ensuring the efficiency and accuracy of reporting the terminal capability information by the subsequent terminal device.

In one possible implementation, the above steps 606 to 612 may be alternatively implemented as the following steps, as shown in fig. 7:

step 701, if the terminal equipment provides the terminal capability information identifier and the core network equipment does not have the terminal capability information identifier reported by the terminal equipment and the corresponding terminal capability information, the core network equipment provides the terminal capability information identifier, the filtering information and the filtering information identifier to the UCMF entity.

Optionally, if the terminal device provides the terminal capability information identifier and the core network device has the terminal capability information identifier reported by the terminal device and the corresponding terminal capability information, the process is ended.

Step 702, the UCMF entity extracts the relevant terminal capability information from its database according to the terminal capability information identifier.

Step 703, the UCMF entity sends the terminal capability information to the core network device.

Optionally, the filtering information identifier in the embodiment of the present disclosure may be broadcasted through a system message, or may be notified through RRC layer signaling, or may be notified through NAS layer signaling. In the following, the three possible implementations described above are described separately using exemplary embodiments.

In the case that the identifier allocated to the PLMN corresponding to the filtering information identifier expected by the access network device exists in the terminal device, please refer to fig. 8, which shows a flowchart of filtering information identifier broadcast by system message provided in the exemplary embodiment of the present disclosure, which may be applicable to start-up registration, periodic TAU update, TAU update caused by location change, and even if the filtering information identifier expected by the network is found to be changed, may actively initiate a flow to update the identifier allocated to the PLMN in the context of the network side. As shown in fig. 8, the registration process includes, but is not limited to, the following steps:

step 801, an access network device sends a system message to a terminal device, where the system message carries a filtering information identifier expected by the access network device in a current cell or area.

The System message includes a Master Information Block (MIB) and a System Information Block (SIB). Optionally, the system message under the NR system includes: MIB, SIB1, or one of other SIBs; the system message under the LTE system comprises: MIB, SIB1, SIB2 and one of the other SIBs.

Optionally, the filtering information identifier is broadcast periodically. Namely, the access network device periodically broadcasts the filtering information identifier to the terminal device through the system message.

Optionally, a system message request mode for requesting a system message (english: On Demand SI) in the NR system is added. That is, the terminal device sends a specific random access prefix or a random access message on a specific random access resource to request to acquire a specific system message. Correspondingly, after receiving the specific random access prefix or the random access message on the specific random access resource, the access network equipment broadcasts the corresponding system message.

The access network device may also send the filtering information identifier expected by the access network device to the core network device. Optionally, the core network device in the NR system includes an AMF entity, and the core network device in the LTE system includes an MME. This embodiment is not limited thereto.

Optionally, the filtering information identifier is in an on-demand system message, and the terminal device requests network broadcasting by sending a request.

Step 802, the terminal device finds out the corresponding terminal capability information identifier according to the filtering information identifier expected by the access network in the access network system message.

The terminal equipment determines a proper terminal capacity information identifier by comparing a filtering information identifier corresponding to the terminal capacity information identifier stored by the terminal equipment with a filtering information identifier expected by the access network equipment.

It should be noted that, the relevant details in the above embodiment may be referred to in the process of the terminal device finding the corresponding terminal capability information identifier according to the filtering information identifier, and are not described herein again.

Step 803, the terminal device sends an NAS message to the core network device, where the NAS message carries the terminal capability information identifier and the filtering information identifier.

Optionally, in the flows of a Registration Request (english: Registration Request), an Attach Request (english: Attach Request), a Tracking Area Update (english: Tracking Area Update), and the like, the NAS message sent by the terminal device to the core network device directly carries the terminal capability information identifier and the filtering information identifier of the terminal device.

In the LTE or NR system, in an RRC Connection Establishment procedure (english: RRC Connection Establishment procedure), an RRC Connection continuation procedure (english: RRC Connection resource procedure), an RRC Connection Reestablishment procedure (english: RRC Connection Reestablishment procedure), an RRC Connection Reconfiguration procedure (LTE: RRC Connection Reconfiguration; NR: RRC Reconfiguration), and an RRC Connection Release procedure (english: RRC Connection Release), the filtering information identifier expected by the network side may be carried in a message sent by the network side device to the terminal device, so as to notify the terminal device of providing the terminal capability information identifier according to the filtering information identifier expected by the network side. Please refer to fig. 9, which shows a flowchart of sending filtering information identifier through RRC layer message according to an exemplary embodiment of the present disclosure, and this embodiment is illustrated by using the method in the mobile communication system provided in fig. 4 or fig. 5. The method comprises the following steps.

In step 901, the terminal device sends an RRC request to the access network device.

And when the equipment state of the terminal equipment is in a non-connection state, the terminal equipment sends an RRC request to the access network equipment.

Optionally, in the NR system, the RRC request includes one of an RRC establishment request, an RRC continuation request, and an RRC reestablishment request.

Optionally, in the LTE system, the RRC request includes one of an RRC connection request, an RRC connection continuation request, and an RRC connection reestablishment request.

Step 902, the access network device sends a first RRC message to the terminal device, where the first RRC message carries the filtering information identifier.

The filtering information is marked as the filtering information expected by the network end equipment.

Optionally, in the NR system, the first RRC message includes: an RRC establishment message, an RRC continuation message, and an RRC reestablishment message.

Optionally, in the LTE system, the first RRC message includes: an RRC connection setup message, an RRC connection continuation message, and an RRC connection reestablishment message.

Step 903, the terminal device finds the corresponding terminal capability information identifier according to the received filtering information identifier.

The terminal equipment determines a proper terminal capacity information identifier by comparing a filtering information identifier corresponding to the terminal capacity information identifier stored by the terminal equipment with a filtering information identifier expected by the access network.

It should be noted that, the relevant details in the above embodiment may be referred to in the process of the terminal device finding the corresponding terminal capability information identifier according to the filtering information identifier, and are not described herein again. Step 904, the terminal device sends an RRC response message carrying the NAS message to the core network device.

Optionally, in the flows of the registration request, the attach request, the tracking area update, and the like, the terminal device sends an RRC response message carrying the NAS message to the core network device.

Optionally, in the NR system, the RRC response message includes: RRC setup complete message or RRC continue complete message. In the LTE system, the RRC-specific signaling message includes: an RRC connection setup complete message or an RRC connection continuation complete message.

Optionally, the filtering information identifier is carried in RRC layer signaling, or the filtering information identifier is carried in NAS layer signaling.

In a possible implementation manner, the RRC response message does not carry the NAS message, and the RRC response message directly carries the filtering information identifier and/or the terminal capability information identifier. And the terminal equipment sends the RRC response message to the access network equipment.

In another possible implementation manner, the NAS message of the RRC response message carries the terminal capability information identifier and/or the filtering information identifier. And the terminal equipment sends the RRC response message carrying the NAS message to the access network equipment or the core network equipment.

Illustratively, the access network device sends the filtering information identifier sent by the terminal device to the core network device, and the core network device compares the filtering information identifier with the filtering information identifier expected by the access network device to determine whether to execute a procedure of acquiring new terminal capability information and allocating a new identifier allocated by a PLMN.

Illustratively, the core network device sends the filtering information identifier sent by the terminal device to the access network device, and the access network device determines whether the filtering information identifier can match the requirement of the access network, so as to determine whether to execute a process of acquiring new terminal capability information and allocating a new identifier allocated by a PLMN.

Based on the security considerations, in the case that the filtering information identifier is considered as sensitive information by the network, if the filtering information identifier is delivered in the non-access stratum, the security protection mechanism of the non-access stratum is started and then can be sent. If the filtering information mark is transmitted in the access layer, the security protection mechanism of the access layer can be sent only after being started. Security protection mechanisms include encryption and integrity protection. Illustratively, if security protection can be started, the NAS message of the NR system directly carries the terminal capability information identifier of the terminal device. If the security protection cannot be started or the NAS message of the LTE system is used, the terminal capability information identifier of the terminal device cannot be directly carried in the NAS message.

If the Security protection cannot be started or the NAS message of the LTE system is used, the terminal capability information identifier of the terminal needs to be carried in a response message of the terminal device in a subsequent NAS layer Security Mode Command (english: Security Mode Command) flow. If the filtering information identifier has the same requirement as the terminal capability information identifier, the filtering information identifier also needs to be carried in the response message of the terminal device.

It should be noted that, in the NR system and the LTE system, the method for carrying the terminal capability information identifier is slightly different.

In the LTE system, when sending the attach request and TAU request messages, the MME entity may indicate in the Security Mode Command that the terminal carries the terminal capability information identifier in the Security Mode Command Accept (english: Security Mode Command Accept) message, where the terminal capability information identifier may only carry an indication for indicating whether the terminal device has an identifier allocated by the currently selected PLMN, and the terminal capability information identifier may only be sent after the authentication and Security protection are successfully established.

In the NR system, the terminal capability information identifier can be directly transmitted at the beginning of registration and terminal configuration update even when security protection is activated, otherwise, only a clear text message is transmitted, and a non-clear text message must be transmitted in a response message of the security mode command flow after security protection is activated.

In one possible implementation, the filtering information identifier is non-sensitive information and can be sent in the clear; in another possible implementation, the filtering information identifier is sensitive information and cannot be sent in the clear, i.e. the filtering information identifier cannot be sent until security protection is started.

Please refer to fig. 10, which shows a flowchart of sending filtering information identifier through RRC layer message according to an exemplary embodiment of the present disclosure, and this embodiment is illustrated by using the method in the mobile communication system provided in fig. 4 or fig. 5. The method comprises the following steps.

Step 1001, the terminal device sends an RRC request to the access network device.

Step 1002, the access network device sends a second RRC message to the terminal device, where the second RRC message carries the filtering information identifier.

Optionally, in the NR system, the second RRC message includes: RRC reject message or RRC release message.

Optionally, in the LTE system, the second RRC message includes: RRC connection reject message or RRC connection release message.

And 1003, the terminal device reports the corresponding terminal capability information identifier to the access network device according to the received filtering information identifier.

The terminal equipment determines a proper terminal capacity information identifier by comparing a filtering information identifier corresponding to the terminal capacity information identifier stored by the terminal equipment with a filtering information identifier expected by the access network, and reports the terminal capacity information identifier to the access network equipment.

It should be noted that, the process of reporting the corresponding terminal capability information identifier to the access network device by the terminal device according to the filtering information identifier may refer to the relevant details in the foregoing embodiment, and details are not described here again.

Optionally, after the terminal device reports the corresponding terminal capability information identifier to the access network device, the device state of the terminal device is executed after being in an idle state, or the above steps 1001 to 1003 are directly executed again.

Optionally, if the terminal capability information identifier is sensitive information and the filtering information identifier is not sensitive information, the terminal device may report only the filtering information identifier to the access network device, and the access network device may compare the expected filtering information identifier with the filtering information identifier reported by the terminal device, and filtering information corresponding to the two filtering information identifiers, and determine whether the terminal capability information identifier that the terminal device may report can meet the requirement of the access network, so as to determine whether to send new filtering information and/or filtering information identifier to the terminal device to obtain new information (the access network device may directly initiate a terminal capability transmission process, or may indicate to the core network device, and the core network device indicates the access network device to initiate a terminal capability transmission process).

Please refer to fig. 11, which shows a flowchart of sending filtering information identifier through RRC layer message according to an exemplary embodiment of the present disclosure, and this embodiment is illustrated by using the method in the mobile communication system provided in fig. 4 or fig. 5.

Optionally, the filtering information identifier and/or the terminal capability information identifier are carried in RRC layer signaling, or the filtering information identifier and/or the terminal capability information identifier are carried in NAS layer signaling.

It should be noted that, for the process of the terminal device sending the RRC response message carrying the NAS message to the core network device, reference may be made to relevant details in the foregoing embodiment, and details are not described here again.

Another point to be noted is that the RRC response message sent by the terminal device to the core network device may not carry the NAS message, and directly carries the filtering information identifier and/or the terminal capability information identifier in the RRC response message.

Optionally, after the terminal device sends the RRC response message carrying the NAS message to the core network device, the method further includes an interaction procedure between the access network device and the core network device. Referring to fig. 12, the method includes the following steps.

Step 1201, the terminal device sends the filtering information identifier to the access network device through RRC layer signaling.

Step 1202, the access network device compares whether the filtering information identifier sent by the terminal device matches the filtering information expected by the access network device.

Step 1203, the access network device indicates whether the capability information of the current terminal of the core network device meets the requirement of the access network.

If the access network equipment compares that the filtering information corresponding to the filtering information identifier sent by the terminal equipment is matched with the filtering information expected by the access network equipment, the access network equipment indicates the capability information of the current terminal of the core network equipment to meet the requirement of the access network; if the filtering information identifier sent by the comparison terminal equipment of the access network equipment is not matched with the filtering information expected by the access network equipment, the access network equipment indicates that the capability information of the current terminal of the core network equipment does not meet the requirement of the access network.

If not, the access network or the core network device may consider to initiate a terminal Capability Transfer (english: UE Capability Transfer) process to reacquire the terminal Capability information and notify the UCMF entity to allocate a new PLMN allocated identifier, and the relevant process may refer to relevant details in the above embodiments and is not described herein again.

Referring to fig. 13, a flowchart illustrating that filtering information is identified by NAS layer message delivery according to an exemplary embodiment of the present disclosure is shown, and this embodiment is illustrated by using this method in the mobile communication system provided in fig. 4 or fig. 5.

In step 1302, the terminal device sends an RRC response message carrying the NAS message to the core network device.

Optionally, in the flows of the registration request, the attach request, the tracking area update, and the like, the terminal device sends an RRC response message carrying the NAS message to the core network device. Wherein, the NAS message carries the filtering information identifier.

Step 1303, the core network device determines whether to execute a procedure of acquiring new terminal capability information and allocating a new identifier allocated by the PLMN according to the filtering information identifier sent by the terminal device.

And the core network equipment receives the filtering information identifier sent by the terminal equipment. In a possible implementation manner, the core network device compares the filtering information identifier sent by the terminal device with the filtering information identifier expected by the access network device to determine whether a process of acquiring new terminal capability information and allocating a new identifier allocated by a PLMN needs to be performed.

In another possible implementation manner, the core network device sends the filtering information identifier sent by the terminal device to the access network device, and the access network device determines whether the filtering information identifier can match the requirement of the access network, so as to determine whether to execute a procedure of acquiring new terminal capability information and allocating a new identifier allocated by a PLMN.

It should be noted that, for the process of acquiring new terminal capability information and allocating a new identifier allocated to a PLMN, reference may be made to relevant details in the foregoing embodiments, and details are not described herein again.

Referring to fig. 14, a flowchart illustrating a method for actively notifying a terminal device of filter information change by a network according to an exemplary embodiment of the present disclosure is shown, where the method is used in the mobile communication system provided in fig. 4 or fig. 5 for example. The method comprises the following steps.

If the access network device finds that the terminal device may enter an area with different capability requirements, and the filtering information identifier applied in the area are not matched with the terminal capability information maintained by the terminal device at the access network device and the core network device currently, determining that the filtering information is changed, and the access network device actively informs the terminal device of the filtering information change through a terminal capability transfer process, and executing step 1402; otherwise, ending the process.

Step 1402, the access network device sends an access network message and a terminal capability query message to the terminal device, where the terminal capability query message carries a filtering information identifier and/or filtering information expected by the access network device.

Step 1403, the terminal device reports the terminal capability information and the filtering information to the access network device (if received).

Optionally, the terminal capability information carries a terminal capability information identifier and a corresponding filtering information identifier.

After receiving the terminal capability query message sent by the access network device, the terminal device obtains the corresponding terminal capability information according to the filtering information identifier and/or the filtering information, and reports the terminal capability information and the filtering information (if received) to the access network device.

It should be noted that, for the process of the terminal device obtaining the corresponding terminal capability information according to the filtering information identifier and/or the filtering information, reference may be made to relevant details in the foregoing embodiments, and details are not described here again.

Step 1404, the access network device reports the terminal capability information to the core network device.
