Detailed Description
It is first pointed out that the capabilities of the terminal can be divided into two kinds, radio capabilities and core network capabilities. For the wireless capability, the terminal can report the wireless capability of the terminal according to the request of the network. For the core network capability, the terminal may report the network capability of the terminal at registration.
A terminal may support multiple frequency bands (bands) and frequencies (frequency). With the introduction of CA (Carrier Aggregation) and DC (Dual Connectivity) technologies, various possible combinations of frequency bands need to be arranged and combined, and the combinations of frequency bands supported by each terminal manufacturer may be different, which results in a huge wireless capability. In addition, as networks evolve, more and more features are introduced into the network, with different features often requiring different wireless capabilities and network capabilities. For the relevant network characteristics, the terminal needs to inform the network of information whether it supports.
Generally, each shipped terminal has Equipment identification information, such as an International Mobile Equipment Identity (IMEI). A Type Allocation Code (TAC) may be included in the IMEI, and the TAC is generally composed of 8 digits (6 digits in the early stage), is a Code for distinguishing a terminal brand and a terminal model, and is allocated by the GSMA and its authority. The first two digits of the TAC are also called an allocation mechanism Identifier (Reporting Body Identifier), which is a code for authorizing the IMEI allocation mechanism, for example, 01 is CTIA in the united states, 35 is BABT in the united kingdom, and 86 is TAF in china. The same terminal model can be uniquely identified through the TAC. While terminal capabilities of the same terminal model tend to be the same.
The IMEI may further include a Software Version Number (SVN), and the SVN may distinguish different Software versions used when terminals of the same model leave the factory. SVN exists only in a partial model of a partial brand. Different SVNs may correspond to different terminal capabilities.
In order to reduce the overhead brought by the reporting of the terminal capability, identification information capable of indicating the terminal capability can be set for the terminal. A method for optimizing terminal ability signaling is that the terminal only reports the identification information indicating the terminal ability to the network. The network can map the terminal capability through the identification information indicating the terminal capability. The terminal capability identification information may be capability identification information indicating the capability of the terminal.
In the embodiment of the present invention, identification information of terminal capability (may be simply referred to as terminal capability identification information) may be used to identify the terminal capability. The terminal capacity identification information and the terminal capacity information have a mapping relation, and the terminal capacity can be mapped through the terminal capacity identification information. The terminal capability identification information may map a set of terminal capabilities or complete terminal capabilities. Because the size of the terminal capacity identification information is smaller than the terminal capacity, the effect of optimizing the capacity-saving signaling can be achieved.
Alternatively, one terminal may have one or more terminal capability identification information.

In order to reduce the overhead brought by the reporting of the terminal capability, identification information capable of indicating the terminal capability can be set for the terminal. A method for optimizing terminal capability signaling is that a terminal only reports identification information indicating the terminal capability to a network. The network can map the terminal capability through the identification information indicating the terminal capability. The terminal capability identification information may be capability identification information indicating the capability of the terminal. When the network does not have the terminal capability mapped by the identification information of the terminal capability, the network can acquire the terminal capability from the terminal. The network may then establish a mapping relationship of the capability identification information of the terminal capability and the terminal capability.
Currently, in order to reduce the radio capability reported by a terminal, a RAN (radio access network) network element may only obtain a subset of the terminal's capability from the terminal. For example, for radio capabilities (such as frequency band) that are not supported by the RAN network element or a combination of frequency bands that are not scheduled strategically, the RAN network element may not request the terminal to report. Therefore, the terminal capabilities acquired by the RAN may be a subset of the terminal capabilities. Different RAN nodes have different capabilities and therefore the acquired terminal capabilities are different.
The embodiment of the invention can solve the following problems:
problem 1: when the terminal capability acquired by the RAN network element to the terminal is a subset of the terminal capability mapped by the terminal capability identification information. When the network establishes a mapping relationship between the terminal capability identification information and the obtained terminal capability subset according to the obtained terminal capability, an error may be caused. When the terminal enters an idle state and accesses a new RAN node, the new RAN node may misinterpret that the terminal capability subset is the full capability set of the terminal. Thereby affecting resource scheduling and the user experience.
Problem 2: a terminal may be configured with multiple capability identifiers, each corresponding to a different capability set. For example, the terminal may have different capability sets corresponding to different operators, and the capability sets may respectively correspond to different terminal capabilities. However, when the terminal accesses to an operator network, only one capability identifier may be reported. The RAT types supported by each operator are different and the required radio capabilities are also different. The complete set of capabilities on the terminal is redundant to the operator network. Such as CDMA wireless capability reported in china unicom, for example, is of no value. The complete terminal capabilities are not necessarily the terminal capabilities mapped by the current terminal capability identity.

In order to reduce the overhead of capability reporting, when the maximum number of uplink carrier units requested by the network is N, even if the terminal has the capability of more than N CCs, the terminal only refers to the capability of reporting the maximum number of CCs requested by the network, such as frequency band combination.

and 402, performing a second relevant operation of the terminal capability according to the capability request information.
In one embodiment, the capability request information may be acquired from at least one of: RAN network element, CN network element, AMF, MME, gNB, eNB. For example, when the first communication device is a RAN network element, the capability request information may be received from a CN network element or other RAN network elements. For example, when the first communication device is a CN network element, the capability request information may be received from other CN network elements or RAN network elements.

The current terminal capability identification may be understood as at least one of: the terminal capacity identification information corresponding to the current terminal capacity, the effective terminal capacity identification information, the latest terminal capacity identification sent by the terminal to the network, the latest terminal capacity identification allocated by the network, the terminal capacity identification information sent by the first communication equipment and the latest terminal capacity identification information sent by the first communication equipment.

The terminal capability mapped by the terminal capability identifier can be ensured to be obtained by displaying the indication information indicating all the terminal capabilities corresponding to the obtained terminal capability identifier.
In addition, the capability request information may refer to the related descriptions of the embodiments shown in fig. 2 and fig. 3, which are not described herein again, and the same beneficial effects can be achieved.
In one embodiment, the complete terminal capability may be obtained by excluding the capability request screening parameter. For example: the complete terminal capability and the current capability identifier of the terminal are mapped one by one, so that the complete terminal capability can be obtained when the capability request screening parameters are not included. In addition, after the complete terminal capability is obtained, the association relationship can be established with the existing terminal capability identifier.
In one embodiment, the terminal may be configured with multiple capability identifiers, the capabilities of terminals mapped by different capability identifiers are different, and the complete terminal capability may not be the terminal capability mapped by the terminal capability identifier. It is easy to understand that the terminal capability mapped by the terminal capability identifier can be ensured to be obtained by displaying the indication information indicating all the terminal capabilities corresponding to the terminal capability identifier.
In one embodiment, the second correlation operation may be performed by requesting indication information of the full terminal capability, such as acquiring the full terminal capability. For example: the third communication equipment is a CN network element. When the CN network element does not have the terminal capability set mapped by the terminal capability identifier information, the CN network element may instruct the RAN network element to acquire the complete capability set of the terminal. The CN network element can establish the mapping relation between the terminal capability identification and the complete capability set after receiving the complete capability set of the terminal sent by the RAN network element. In this embodiment, the CN network element can indicate the RAN network element to acquire the complete capability set of the terminal. In this embodiment, the interface message (e.g., S1 message (e.g., initial UE context setup request message) and/or NG message (e.g., initial UE context setup request message)) between the CN network element and the RAN network may include indication information requesting to acquire the complete terminal capability. For example, the third communication device is a RAN network element. When the RAN network element does not have the terminal capability set mapped by the terminal capability identification information, the RAN network element may instruct the terminal to report the complete capability set of the terminal. After receiving the complete capability set of the terminal, the RAN network element may establish a mapping relationship between the terminal capability identifier and the complete capability set and/or send the acquired terminal capability to the CN network element. In this embodiment, the UE capability query message may include indication information requesting to acquire the complete terminal capability.

Wherein the information whether the capability signaling optimization is supported or not indicates support may refer to at least one of: the terminal has the capability signaling optimization capability, the network has the capability signaling optimization capability, and both the terminal and the network have the capability signaling optimization capability. For example: the third communication equipment is a CN network element. The CN network element may send information whether the capability signaling optimization is supported to the terminal in the registration process. When the information whether the capability signaling optimization is supported indicates support, and when a capability acquisition request (such as an RRC message of UE capability query) sent by the network is received, the terminal may skip or ignore the capability request screening parameter, and return the terminal capability set or the complete capability set mapped by the current terminal capability identifier to the network. Such as: the third communication device is a RAN network element. The RAN network element may send (such as broadcast in system information, sent in RRC message 5, or sent in a UE capability query message) information to the terminal whether capability signaling optimization is supported. When the information whether the capability signaling optimization is supported indicates support, and when a capability acquisition request (such as an RRC message for UE capability query) sent by the network is received, the terminal may ignore the capability request screening parameter, and return a terminal capability set mapped by the current terminal capability identifier, a complete terminal capability set, or a complete terminal capability satisfying the first condition to the network.
In another embodiment, the terminal capability may be acquired through the indication information of the capability request filtering parameter. For example: the third communication device is a RAN network element or a CN network element. And the third communication equipment sends the indication information of the capability request screening parameters to the terminal. And the terminal skips or ignores the capability request screening parameters according to the indication information of the capability request screening parameters and returns the complete terminal capability to the network.
In another embodiment, the second correlation operation may be performed by skipping or ignoring capability request filter parameters. For example: the third communication device is a RAN network element. The RAN network element indicates to the terminal the skipped or ignored capability request screening parameter. And the terminal skips or ignores the capability request screening parameter according to the indicated skipped or ignored capability request screening parameter and returns the complete terminal capability or the terminal capability meeting certain conditions to the network. The certain condition may be a capability request screening parameter that does not indicate skipping or ignoring.
In another embodiment, the capability request screening parameter may be understood as at least one of the following: and sending the terminal capability and the complete capability which does not need to be reported according to the requirement of the capability screening parameter.

For multiple acquisition modes, the capability request screening parameters can still be set. And different values of the screening parameters are set by the capability request, so that a subset of the terminal capabilities is obtained and then combined into the complete terminal capabilities.
