detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present application. It is a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

In addition, the term "and/or" herein is merely an association relationship describing an associated object, indicating that there may be three relationships, for example, A and/or B, which may indicate that A exists separately, and A and B exist at the same time. There are three cases of B alone. In addition, the character "/" in this document generally indicates that the contextual object is an "or" relationship unless otherwise specified. It should be understood that in the description of the embodiments of the present application, the terms “first” and “second” are used only to distinguish the purpose of description in some cases, and are not to be understood as indicating or implying relative importance. It cannot be understood as an indication or an implied order.

First, the related knowledge of the embodiment of the present application is introduced.

In the Long Term Evolution (LTE), when the base station needs the capability information of the UE but does not store the capability information of the UE, the base station may send a UE capability query message to the UE. After receiving the UE capability query message, the UE reports the UE. The capability information is sent to the base station. Further, the base station can store the UE capability information and forward it to the Mobility Management Entity (MME) for storage. When the UE moves to the coverage of the other base station, the other base station first acquires the capability information of the UE from the MME, and if obtained, the other base station directly uses the capability information acquired from the MME, if not obtained, Other base stations send UE capability query messages to the UE. For each UE, the MME may store two capability containers for it, one for the conventional UE capability and one for the paging capability of the UE.

In the Uplink Data Compression (UDC) technology of the wireless communication system, the UE compresses the uplink application layer data or signaling, and the base station side decompresses the compressed data to save the amount of data transmitted by the air interface and save uplink resources. . When UDC technology is adopted, there are two schemes for the UE and the base station to maintain correct compression and decompression. One is that the UE establishes the data content in the compression buffer in the process of transmitting the uplink data, and the base station side reserves, and then the base station decompresses with corresponding rules. The other is that the UE and the base station download, pre-define or save some profile information for compression and decompression in advance, and the UE and the base station can determine which profile information is enabled through some signaling interaction, and once the profile information is agreed, It is possible to ensure that the UE and the base station are properly compressed and decompressed.

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

At present, the UDC technology can only compress the data on the Data Radio Bearer (DRB), and does not compress the data on the Signal Radio Bearer (SRB), so the signaling of the data on the SRB. The consumption is relatively large. To be clear, even if the UDC technology can be used to compress the data on the SRB, the UE capability information obtained by the base station from the SRB is still uncompressed, and the base station sends the obtained uncompressed UE capability information to the core network. Will occupy a large storage space of the core network.

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

In the method and apparatus provided by the embodiments of the present application, a UE capability information dictionary for UE capability information is predefined, and each UE in the wireless communication system compresses using a predefined UE capability information dictionary before reporting the capability information, and obtains compression. The UE capability information compression packet is reported to the base station as a UE capability message, and the core network stores the UE capability information compression packet, so that each base station in the wireless communication system can obtain the UE capability information compression packet from the core network, and the base station is from the core network or After acquiring the UE capability information compression packet, the UE may decompress the UE capability information compression packet by using a predefined UE capability information dictionary, and obtain capability information of the UE.

The reporting method, the acquiring method, and the processing method of the UE capability information provided by the embodiment of the present application 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, 1. The UE, the first base station, the second base station, and the core network control node shown in FIGS. 2 and 3. The first base station and the second base station may be the same base station or different base stations, and when the base station is a different base station, the first base station may also perform the method performed by the second base station, and the second base station may also perform the method. A method performed by a base station.

In this embodiment, the UE, the first base station, and the second base station both store the same predefined UE capability information dictionary and compression algorithm, and the predefined UE capability information dictionary may be one or more, 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 report. The predefined compression algorithm can be a deflate compression algorithm or other standardized compression algorithms.

In a possible implementation manner, any one of the predefined UE capability information dictionaries includes one or more of the following information:

(1) A character string having a frequency higher than a preset threshold in a capability report message of a plurality of predetermined typical terminals, for example, the character string is a character appearing at a high frequency in a plurality of Radio Resource Control (RRC) messages. string;

(2) one or more predetermined capability reporting messages of a typical terminal, for example, wherein the capability reporting message is 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 the capability information of the radio frequency, physical layer and layer 2 of one terminal.

In the capability information dictionary, a flowchart of a method, an acquisition method, and a processing method for performing reporting of UE capability information by each device in the wireless communication system.

Please refer to Figure 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 the UE capability query information to the UE, where the UE capability query message is used to instruct the UE to report its own UE capability information.
