Terminals with different capabilities and different uses have also emerged. The network segment needs to know the capabilities that the terminal has in order to configure different resources according to the different capabilities of the terminal. In the existing protocols and schemes, the problem is solved by means of network query and capability report of the mobile terminal. The signaling flow is shown in fig. 1: 1. a mobile management entity MME sends an initial context establishment request; 2. if the initial context establishing request does not carry the wireless capability of the terminal, the base station eNB sends a terminal capability query message; 3. the terminal reports the wireless capability of the terminal to the base station; 4. and the base station sends the terminal capability information to a Mobile Management Entity (MME).
In the existing protocols and schemes, the terminal side reports the capability according to the query indication after receiving the capability query message of the base station, and the terminal itself does not actively report the capability.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
First embodiment
As shown in fig. 2, a first embodiment of the present invention provides a method for reporting capability information of a terminal, including:
and step 22, actively reporting the capability information of the terminal to a network side according to the requirement information.
In the first embodiment of the present invention, the terminal can trigger the reporting operation of the capability information according to the own requirement information, specifically, when the requirement information of the terminal changes, the terminal actively reports the capability information to the network side.
Specifically, whether the demand changes or not can be judged by the service type of the terminal, that is, step 21 includes:
step 211, when the terminal performs service switching, obtaining the requirement information which is reported by the capability information of the triggering terminal and is matched with the switched service.
In the above embodiments of the present invention, whether the requirement information of the terminal changes may be determined by whether the terminal performs service switching. When the terminal is switched from the first service to the second service, acquiring the requirement information matched with the second service, wherein the requirement information can trigger the reporting of the capability information of the terminal.
Specifically, when the terminal reports the capability information, the terminal may report the complete capability information, or report the capability information of a different part from the last reported capability information. Specifically, step 22:
step 221, according to the requirement information, actively reporting the second capability information of the terminal matched with the switched service to the network side.
That is, after the terminal performs service switching, it does not determine whether the capability information changes, and directly reports the capability information matched with the switched service to the network side.
Alternatively, step 22 comprises:
step 222, acquiring second capability information of the terminal matched with the switched service according to the requirement information;
step 223, comparing the second capability information with the first capability information reported by the terminal before service switching, and determining whether the capability information changes;
step 224, if the capability information does not change, not reporting the second capability information to the network side; if the capability information changes, the capability information different from the first capability information in the second capability information is actively reported to the network side and the domain with the changed capability information is identified.
Specifically, after the terminal performs service switching, it further determines whether the capability information changes. If the capability information is not changed, the capability information is not reported to the network side, so that signaling resources are saved, and resource waste is reduced; when the capacity information changes, only the changed part is reported after comparing with the last capacity reporting information when the capacity information is reported, and the unchanged part is not reported; and identifies the domain where the capability information changes when the capability information is reported. The network side can determine which part of the capability information has changed according to the identifier of the network side, and then determine why the change occurs according to the specific content reported by the capability information.
And the capability information of the terminal also comprises: and indicating the capability information to be the indication information reported by the terminal independently. That is, after receiving the capability information, the network side can know whether the capability information is reported by the terminal autonomously or is reported after being queried by the network side.
For example, the ue-Trigger is used to identify whether the capability information of the terminal is autonomously reported by the terminal, when the ue-Trigger is TRUE, the capability message is initiated autonomously by the terminal, and when the ue-Trigger is FALSE, the capability message is triggered by the network. The modification Field (modification Field) is in a bitmap (bitmap) format, and when bit n is 1, it indicates that the corresponding Field is changed. For example, bit 1 corresponds to the list of radio access technology capabilities of the terminal, bit2 corresponds to radio paging info of the terminal-r 12. When bit 1 is 1, the list indicating the radio access technology Capability of the terminal is changed, and the network only updates the local radio access technology Capability (Capability RAT) information according to the setting.
Further, step 22 in the above embodiment of the present invention further includes:
reporting the capability information of the terminal to a network side through a capability reporting signaling; alternatively, the first and second electrodes may be,
and reporting the capability information of the terminal to a network side through a service request signaling of the NAS message.
As shown in fig. 3, in the above embodiment of the present invention, the terminal still reports the capability information through the original capability reporting signaling. For example, when a terminal registers on the network, it may autonomously report the terminal capability change information to the network (specifically, the terminal autonomously sends capability information to the base station to notify the base station that the terminal capability information has changed; after the base station receives the capability information report of the terminal, the base station updates the locally stored related capability information and forwards the capability information to the mobility management entity MME, and after the MME receives the capability information, the locally stored related capability information is also updated). And the network terminal updates the original information stored locally according to the capability information reported by the terminal and performs reasonable resource allocation and control according to the latest capability reporting condition.
Or, the capability information reported by the terminal may be reported to the network through a non-access stratum (NAS) message, which is SERVICE REQUEST signaling (SERVICE REQUEST).
Both of the above two manners of reporting capability information are applicable to the present application.
In the foregoing embodiment of the present invention, the capability information of the terminal includes: one or more of a radio access technology Capability (Capability RAT) of the terminal, a security performance of the terminal, and a type (Category) of a radio access technology of the terminal.
In summary, in the first embodiment of the present invention, the terminal actively reports the capability information of the terminal to the network side through the capability reporting signaling or the service request signaling of the NAS message, so that the network side can perform reasonable resource allocation and control according to the latest capability information; the reporting method of the capability information provided by the embodiment of the invention is realized based on the existing protocol flow, the realizing method is simple, the existing flow can be compatible, and the compatibility is high.
