Wherein, for each UE, the MME may store two capability containers (containers) for it, one for housing regular UE capabilities and one for housing paging capabilities of the UE.

In an Uplink Data Compression (UDC) technology of a wireless communication system, a UE compresses Data or signaling of an Uplink application layer, and a base station side decompresses the compressed Data to save Data volume transmitted over an air interface and save Uplink resources. When the UDC technology is adopted, two schemes of keeping correct compression and decompression by the UE and the base station are adopted, wherein one scheme is that the UE establishes data content in a compression cache in the process of sending uplink data, the base station side is reserved, and then the base station carries out decompression according to a corresponding rule; the other is that the UE and the base station download, predefine or store some configuration (profile) information for compression and decompression in advance, and the UE and the base station may determine which profile information is enabled through some signaling interaction, and once the profile information is agreed, it may be ensured that the UE and the base station perform compression and decompression correctly.

The profile information may include a compression method, and information of a buffer (buffer) for decompression or a mapping (mapping) table for decompression. In the LTE system, there are two kinds of preset dictionaries for the UDC technology, one is a dictionary defined in the standardized RFC 3485 and used for Session Initiation Protocol (SIP) signaling compression, and the other is a dictionary defined by an operator. The UE may store only one operator-defined dictionary.

Currently, the UDC technology can only compress Data on a Data Radio Bearer (DRB), but does not compress Data on a Signaling Radio Bearer (SRB), so that the signaling consumption of Data on the SRB is relatively large. To put it back, even though the UDC technology may be used to compress data on the SRB, the UE capability information obtained from the SRB by the base station is still uncompressed, and the base station sends the obtained uncompressed UE capability information to the core network, which still occupies a large storage space of the core network.

The method and apparatus provided by the embodiments of the present invention will be described with reference to the accompanying drawings.

The method and the device provided by the embodiment of the invention have the main idea that a UE capacity information dictionary related to UE capacity information is predefined, each UE in a wireless communication system adopts the predefined UE capacity information dictionary for compression before reporting the capacity information, and reports a compressed UE capacity information packet obtained by compression to a base station as a UE capacity message, and a core network stores the UE capacity information compressed packet.

The reporting method, the obtaining method, and the processing method of the UE capability information provided in the embodiments of the present invention may be applied to a wireless communication system, where the wireless communication system includes a UE, a first base station, a second base station, and a core network control node, for example, the UE, the first base station, the second base station, and the core network control node shown in fig. 1, fig. 2, fig. 3, and fig. 9. The first base station and the second base station may be the same base station or different base stations, and when the base stations are different base stations, the first base station may also execute the method executed by the second base station, and the second base station may also execute the method executed by the first base station.

In the embodiment of the present invention, the UE, the first base station, and the second base station all store the same predefined UE capability information dictionary and compression algorithm, and the predefined UE capability information dictionary may be one or more, and correspondingly, the predefined UE capability information dictionary stored by the UE, the first base station, and the second base station may be one or more.

The predefined UE capability information dictionary contains predetermined data about UE capability information in the UE capability information reporting. The predefined compression algorithm may be a deflate compression algorithm or other standardized compression algorithm. In one possible embodiment, any one of the predefined UE capability information dictionaries contains one or more of the following information:

(1) a plurality of predetermined character strings whose frequency is higher than a preset threshold appear in a capability report message of a typical terminal, for example, the character strings are character strings that appear at a high frequency in a plurality of Radio Resource Control (RRC) messages;

(2) capability reporting messages of one or more predetermined typical terminals, for example, wherein the capability reporting messages are all a complete RRC message;

(3) one or more capability information sets of one or more predetermined typical terminals, for example, the capability information set may include all capability information of radio frequency, physical layer and layer two of one terminal.

The typical terminal may refer to a certain terminal sold in the market, the plurality of typical terminals may refer to terminals of different brands, and of course, the typical terminal may also refer to a terminal selected manually according to other rules.

In a possible embodiment, the process of making the predefined UE capability information dictionary may be to generate a UE capability report message according to the predetermined capability of one or more typical terminals, concatenate one or more different UE capability messages into a UE capability dictionary, and define the dictionary as a standard dictionary in the protocol. One possible structural form of the UE capability information dictionary may be as shown in table 1:

Fig. 1 is a flowchart illustrating a method for reporting, a method for acquiring, and a method for processing UE capability information performed by each device in a wireless communication system when a predefined UE capability information dictionary exists; fig. 2 is a flowchart illustrating a method for reporting, a method for acquiring, and a method for processing UE capability information executed by each device in a wireless communication system when a predefined UE capability information dictionary exists.

Please refer to fig. 1, which includes the following steps:

step 101: when the first base station needs to acquire the UE capability information from the UE, the first base station sends UE capability query information to the UE, wherein the UE capability query information is used for indicating the UE to report the UE capability information of the first base station.

Step 102: after receiving the UE capability query message sent by the first base station, the UE generates a UE capability report message according to the UE capability information of the UE, and compresses the generated UE capability report message according to a predefined UE capability information dictionary and a compression algorithm to obtain a UE capability information compression packet. The UE capability reporting message may be a set of UE capability information and is an uncompressed message.

Step 103: and the UE sends the UE capability information compression packet to the first base station.

In a possible implementation manner, as shown in fig. 3, the UE capability information compressed packet sent by the UE to the first base station in step 103 may be sent by being carried in a UE capability information compressed packet report message or other uplink signaling messages sent by the UE to the first base station, for example, the UE capability information compressed packet may be sent to the first base station by being carried in a container (container) included in the UE capability information compressed packet report message or other uplink signaling messages.

The reporting message of the UE capability information compression packet is a predefined message for reporting the compressed reporting message of the UE capability information, and other uplink signaling messages are different from the reporting message of the UE capability information compression packet. That is, in one transmission mode, compared with the prior art, a UE capability information compressed packet reporting message which is specially used for reporting a compressed UE capability reporting message is newly defined, and the UE transmits a UE capability information compressed packet through the newly defined message; in another sending mode, a new message is not specially defined for reporting the compressed UE capability report message, and the UE carries the UE capability information compressed packet in other uplink signaling messages, such as RRC connection setup complete message, and sends the other uplink signaling messages to the first base station. When the scheme of reporting the UE capability information compressed packet report message is adopted, since the UE capability information compressed packet report message is a newly defined message dedicated to reporting the compressed UE capability report message, the first base station may determine, according to the message, that the information carried in the container included in the message is the compressed UE capability report message; when other uplink signaling messages are adopted for reporting, the other uplink signaling messages may also carry a compression identifier for indicating that the UE capability information carried in the other uplink signaling messages is a compressed UE capability reporting message.

For example, the form of the uplink signaling message carrying the UE capability information compressed packet for reporting the UE capability information may be:

step 104: the first base station sends a UE capability information compression packet and a compression identifier to the core network control node, wherein the compression identifier is used for marking the sent UE capability information compression packet as compressed data, namely informing the core network control node that the UE capability information is carried in the form of the compression packet.

In a possible implementation manner, as shown in fig. 3, in step 104, the UE capability information compression packet and the compression identifier sent by the first base station to the core network control node may be sent by being carried in a UE capability indication message sent by the first base station to the core network control node.

Step 105: after receiving the UE capability information compression packet sent by the UE, the first base station decompresses the UE capability information compression packet according to a predefined UE capability information dictionary and a compression algorithm, and obtains an uncompressed UE capability report message. And, since the UE capability information dictionary and the compression algorithm predefined by the UE and the first base station are the same, the first base station can decompress successfully.

When the UE capability information compressed packet is carried in a container included in a UE capability information compressed packet report message or other uplink signaling messages, a process of the first base station receiving the UE capability information compressed packet sent by the UE may be to obtain the UE capability information compressed packet from the container included in the UE capability information compressed packet report message or other uplink signaling messages.

It should be noted that, in the embodiment of the present invention, the execution order of step 104 and step 105 is not limited, step 104 and step 105 may be executed simultaneously, step 104 may also be executed before step 105 is executed, and step 104 may also be executed after step 105 is executed.

Step 106: after receiving the UE capability information compression packet and the compression identifier sent by the first base station, the core network control node stores the UE capability information compression packet and the compression identifier, so that when the base station needs to obtain the capability information of the UE, the core network control node can directly obtain the UE capability information compression packet from the base station.

Step 107: the second base station transmits a context setup request message to the core network control node, the context setup request message indicating a request to set up a context (context) of the UE.

Step 108: and the core network control node sends the stored UE capability information compression packet and the compression identifier of the UE to the second base station according to the received context establishment request message, so that the second base station can obtain the UE capability information of the UE by decompressing the UE capability information compression packet.

In a possible implementation manner, as shown in fig. 3, the UE capability information compression packet and the compression identifier sent by the core network control node to the second base station in step 108 may be sent by being carried in a context setup response message sent by the core network control node to the second base station.

Step 109: after receiving the UE capability information compression packet and the compression identifier sent by the core network control node, the second base station may determine, through the compression identifier, that the received UE capability information compression packet is a compressed UE capability report message, and then decompress the UE capability information compression packet according to a predefined UE capability information dictionary and compression algorithm, to obtain an uncompressed UE capability report message. And, since the UE capability information dictionary and the compression algorithm predefined by the UE and the second base station are the same, the second base station can decompress successfully.

Referring to fig. 2, when there are multiple predefined UE capability information dictionaries, there are differences between steps 102-106 and steps 108-109, compared to the situation that there is one predefined UE capability information dictionary as shown in fig. 1. When the number of the predefined UE capability information dictionaries is multiple, the number of the predefined UE capability information dictionaries stored by the UE, the first base station, and the second base station is multiple, and when the UE, the first base station, and the second base station use the predefined UE capability information dictionaries to generate or decompress the UE capability information compression packet, there are multiple choices.

Differences between steps 102 to 106 and steps 108 to 109 in fig. 1 and fig. 2 will be described below, except for the differences described below, the remaining contents of the process shown in fig. 2 are the same as those of the process shown in fig. 1, and thus are not described again here.

Referring to fig. 2, when the predefined UE capability information dictionary is multiple:

(1) in step 102, when the UE compresses the UE capability report information to generate a UE capability information compression packet, one of the multiple preset UE capability information dictionaries needs to be selected for compression.

(2) In step 103, the UE needs to send a dictionary identifier to the first base station in addition to the UE capability information compression packet to the first base station, where the dictionary identifier is used to identify a dictionary adopted by the UE when compressing the UE capability report message in the multiple predefined UE capability information dictionaries, so that the first base station can decompress the UE capability information compression packet according to the dictionary identified by the dictionary identifier. The dictionary identifier may be, for example, a number (ID) of the dictionary.

In a possible implementation manner, as shown in fig. 3, the dictionary identifier sent to the first base station may be carried in a UE capability information compression packet report message or other uplink signaling message sent by the UE to the first base station together with the UE capability information compression packet.

For example, the form of the uplink signaling message carrying the UE capability information compression packet and the dictionary identifier for reporting the UE capability information may be:

(3) in step 104, the first base station needs to send the dictionary identifier to the core network control node in addition to the UE capability information compression packet, so that when the second base station obtains the UE capability information compression packet from the core network control node, the second base station can also obtain the corresponding dictionary identifier, thereby implementing correct decompression.

In a possible implementation manner, as shown in fig. 3, the dictionary identifier, the UE capability information compression packet, and the compression identifier sent by the first base station to the core network control node may be carried in a UE capability indication message sent by the first base station to the core network control node.

(4) In step 105, after receiving the UE capability information compression packet and the dictionary identifier, the first base station decompresses the UE capability information compression packet according to the dictionary identified by the dictionary identifier and the predefined compression algorithm in the process of decompressing the UE capability information compression packet, and obtains an uncompressed UE capability report message.

(5) In step 106, the core network control node needs to store the dictionary identifier in addition to the UE capability information compression packet and the compression identifier.

(6) In step 108, the core network control node needs to send the dictionary identifier to the second base station in addition to the UE capability information compression packet and the compression identifier to the second base station.

In a possible implementation manner, as shown in fig. 3, the dictionary identifier, the UE capability information compression packet, and the compression identifier sent by the core network control node to the second base station may be carried in a context setup response message sent by the core network control node to the second base station.

(7) In step 109, after receiving the UE capability information compression packet and the dictionary identifier, the second base station decompresses the UE capability information compression packet according to the dictionary identified by the dictionary identifier and the predefined compression algorithm in the process of decompressing the UE capability information compression packet, and obtains an uncompressed UE capability report message.

Through one or more technical schemes, the signaling load of the UE reporting the UE capability can be reduced, and the storage overhead of the core network control node on the UE capability can be reduced.

It should be noted that, when the reporting method, the obtaining method, and the processing method of the UE capability information provided in the embodiment of the present invention are described above with reference to fig. 1 to fig. 3, for convenience of understanding, the methods are integrated together in steps 101 to step 109 for description, and in a specific implementation process, the reporting method, the obtaining method, and the processing method of the UE capability information provided in the embodiment of the present invention may be integrated together for execution, or may be executed separately for execution. The method for reporting UE capability information may include steps executed by the UE in fig. 1 to 3, one method for acquiring UE capability information may include steps executed by the first base station in fig. 1 to 3, another method for acquiring UE capability information may include steps executed by the second base station in fig. 1 to 3, and the method for processing UE capability information may include steps executed by the core network control node in fig. 1 to 3.

Currently, in a UE capability signaling optimization project, there is an optimization scheme based on a UE capability (capability) identifier (Identity, ID), and the basic idea is that the capability of the UE is associated with one UE capability ID, and the UE only needs to report the UE capability ID, and the base station can obtain the capability of the UE through a mapping relationship, thereby reducing signaling overhead of an air interface and a network interface. Because the UE existing in the market is classified according to manufacturers, models and the like, the types of the UE are not many, and the capabilities of the terminals of the same manufacturer and model are the same, so that the terminals with the same capabilities do not need to report complete UE capability information again as long as the network side has the same terminal to report the UE capabilities, and the network can know the specific capabilities of the UE directly through the UE capability ID.

In view of this, in the embodiment of the present invention, the UE and the base station may generate the actual UE capability corresponding to the UE capability ID into a UE capability dictionary set indexed based on the UE capability ID, and the UE and the base station determine the UE capability dictionary used through the UE capability ID. When a UE with new UE capabilities enters the network, the network and the terminal update the UE capability dictionary based on the new UE capabilities and their corresponding new UE capabilities IDs. For example, fig. 8 is a diagram illustrating UE capability ID as a UE capability information dictionary index.

Referring to fig. 9, when the terminal reports the terminal capability, the UE capability information dictionary is used to compress the generated terminal capability reporting message, the reporting message carries the UE capability ID and the compressed information, and the compressed UE capability is put into the container in the terminal compression capability reporting message. And after receiving the UE capability information report message, the base station maps the UE capability information report message to a corresponding UE capability dictionary according to the UE capability ID in the report message, and decompresses the compressed packet of the UE capability information message by using the dictionary to obtain the UE capability information message.

In a possible implementation manner, in step 102, when the UE compresses the UE capability reporting information to generate the UE capability information compression packet when the number of the predefined UE capability information dictionaries is multiple, one of the multiple predefined UE capability information dictionaries needs to be selected for compression.

In a possible implementation manner, in step 103, the UE needs to send, in addition to the UE capability information compression packet to the first base station, a UE capability ID corresponding to a dictionary that is used in the predefined UE capability information dictionary when compressing the UE capability report message to the first base station, and for convenience of description, a dictionary that is used in the predefined UE capability information dictionary when compressing the UE capability report message in step 102 is referred to as the first UE capability ID.

In a possible implementation manner, when step 105 is executed, the first base station may decompress according to the first UE capability ID reported by the UE, or determine to use the first UE capability ID for decompression according to predefined or preconfigured information, which is not limited in this embodiment of the present invention. After decompressing the UE capability information compressed packet according to the first UE capability ID, the first base station may use the decompressed UE capability information as a new UE capability dictionary, and if a message reported by the UE at this time includes a UE capability ID (i.e., a second UE capability ID) corresponding to the decompressed UE capability information, the first base station generates a new UE capability information dictionary from the UE capability information and the second UE capability ID, and correspondingly stores the new UE capability information dictionary in the UE capability information dictionary set.

In a possible implementation manner, in step 104, the first base station may forward the compressed or uncompressed UE capability information packet to the core network control node for storage, and if the compressed UE capability information packet is compressed, notify the core network control node that the compressed UE capability information packet is compressed data (e.g., a compression identifier occurs).

With continued reference to fig. 9, in a possible implementation manner, the embodiment of the present invention may further use the modification of the terminal capability dictionary RRC message of the UE capability ID to update the UE capability information dictionary: when the capability information of the UE is updated, if the UE capability ID corresponding to the capability information of the UE does not exist in the system, the UE capability ID corresponding to the capability information of the UE (that is, the first UE capability ID) may be used for compression, and in step 103, while the UE reports the UE capability information compression packet, the UE may also report a new UE capability ID (the second UE capability ID) corresponding to the capability information of the UE in a report message to the first base station.

In a possible implementation manner, when step 106 is executed, the core network control node determines the received new UE capability ID and the UE capability corresponding to the new UE capability ID, and updates the UE capability dictionary set if the stored UE capability dictionary set does not have the capability.

Further, if a new UE capability ID (i.e., a second UE capability ID) is also included in the reported message, a new UE capability dictionary is generated based on the second UE capability ID and the UE capability information corresponding to the second UE capability ID, and is stored in the UE capability dictionary set.

In a possible implementation manner, in executing step 108, the core network control node may send the new UE capability dictionary to other base stations (e.g., a second base station) connected thereto, and the second base station also determines to update the UE capability dictionary set after receiving the new UE capability dictionary.

In a specific implementation process, the core network control node may actively send the dictionary update to other base stations, or may not actively send the dictionary update to other base stations, but send the information to the queried base station when the base station queries the core network for the UE capability information corresponding to the second UE capability ID.

In a specific implementation process, the core network control node may send the compressed UE capability information to the second base station, or may directly send the uncompressed UE capability information to the second base station, which is not limited in the embodiments of the present invention.

For example, after receiving the context setup request message sent by the second base station (step 107), the core network control node compresses the UE capability information obtained from the first base station based on the UE capability information dictionary mapped by the first UE capability ID, and sends the generated compressed packet and the second UE capability ID to the second base station (step 108); after receiving the second UE capability ID and the compressed packet, the second base station decompresses the UE capability information compressed packet according to a predefined or configured compression algorithm and the UE capability information dictionary mapped by the first UE capability ID, obtains corresponding UE capability information, and generates a new UE capability information dictionary based on the second UE capability ID and its corresponding UE capability information (step 109).

In the specific implementation process, the core network control node may also directly send uncompressed UE capability information. For example, after receiving the context setup request message sent by the second base station (step 107), the core network control node directly sends the UE capability information and the second UE capability ID to the second base station (step 108); after receiving the UE capability information and the second UE capability ID, the second base station generates a new UE capability information dictionary based on the second UE capability ID and its corresponding UE capability information (step 109).

For ease of understanding, one possible UE reporting details of the UE capability message is illustrated here:

in the above message, the Ue-capability ID is a type definition of the Ue capability ID, and the specific type is not limited, and may be shaping, enumeration, bit stream, byte stream, or the like;

UE-capability compressed ID is used to indicate which UE capability ID corresponds to the UE capability dictionary (i.e. the first UE capability ID) for compression;

the UE-capability ID is used to indicate to report a UE capability ID of the UE, that is, a UE capability ID corresponding to the decompressed UE capability (that is, a second UE capability ID);

the UE-Compressed capability container is data obtained by compressing the UE capability corresponding to the UE capability ID by using the UE capability dictionary corresponding to the UE-Compressed capability ID;

in a specific implementation process, the information may be carried by using a UE capability report message, or may be carried in other uplink signaling messages, such as an RRC connection setup complete message or a newly added RRC message. The first base station may decompress using the dictionary indicated by the ue-Capability CompressedID according to the information carried in the message.

It should be noted that, when the reporting method, the obtaining method, and the processing method of the UE capability information provided in the embodiment of the present invention are described above with reference to fig. 9, for convenience of understanding, the methods are introduced by integrating steps 101 to 109, and in a specific implementation process, the reporting method, the obtaining method, and the processing method of the UE capability information provided in the embodiment of the present invention may be executed by integrating together or may be executed separately. The method for reporting UE capability information may include the step executed by the UE in fig. 9, one method for acquiring UE capability information may include the step executed by the first base station in fig. 9, another method for acquiring UE capability information may include the step executed by the second base station in fig. 9, and the method for processing UE capability information may include the step executed by the core network control node in fig. 9.
