Problems solved by technology

[0006] For terminals that develop Band38+Band39 cross-band carrier aggregation capabilities based on Band38 terminal capabilities, they have the ability to work on China Mobile's network in terms of hardware capabilities, but because 3GPP does not have a Band38+Band39 radio frequency standard (and currently only my country uses Band39 , there is no requirement for Band38+Band39 aggregation in other countries, and there will be no need for Band38+Band39 project establishment in the short term), so the terminal cannot perform the Band38+Band39 carrier aggregation network access test, and the terminal cannot report the ability to support Band38+Band39 aggregation, even if it reports to the base station The corresponding carrier aggregation service cannot be provided for it

Embodiment 1

[0092] A method for virtual mapping of frequency band support capabilities provided by an embodiment of the present invention is applied to a terminal whose device capabilities (such as hardware capabilities and software capabilities) support multiple operating frequency bands, and support a combination of two or more operating frequency bands. The combination of carrier aggregation working frequency bands (for convenience of reference, this combination is referred to as the first combination in this embodiment). The first combination is not defined in the existing standard (such as the 3GPP standard), that is, the first combination does not exist in the carrier aggregation combination of the existing standard. Since the existing standard does not define the first combination, the combination reported in the existing carrier aggregation combination report message cannot report the combination, so the first combination cannot be reported to the network side without modifying the...

Embodiment 2

[0124] The method for virtual mapping of the frequency band support capability of the present invention will be described from the network side below, please refer to image 3 As shown, the method includes the steps of:

[0125] Step 31: Receive carrier aggregation working frequency band information supported by the terminal and information about the working frequency band supported by the terminal reported by a terminal according to a predetermined standard, the carrier aggregation working frequency band information includes the carrier aggregation frequency band supported by the predetermined standard A first combination.

[0126] Here, the network side receives the first combination of carrier aggregation working frequency bands supported by the terminal and the working frequency bands supported by the terminal sent by the terminal. According to the description in the previous embodiment, the supported carrier aggregation working frequency band combination (the first combi...

Embodiment 3

[0160] The present invention will be further described below through a specific example including the behavior of the terminal and the network side.

[0161] In this example, assume that the hardware capability of a certain terminal supports working on Band38 and Band39, and supports carrier aggregation on Band39+Band38, but the existing 3GPP standard does not support Band39+Band38 aggregation, which supports Band39+Band41 Aggregation, therefore, the existing technology cannot realize the reporting of the carrier aggregation capability supported by the terminal through the reporting message stipulated in the existing standard.

[0162] This example can be handled as follows on the terminal side:

[0163] 1. The terminal configures the terminal's "supported carrier aggregation working frequency band combination" information, the specific method is as follows:

[0164] 1) The terminal judges whether the carrier aggregation working frequency band combination it supports is suppo...

Abstract

The present invention provides a method and device for virtual mapping of frequency band support capability. In the present invention, the terminal configures "virtual carrier aggregation working frequency band" information, as well as "supported LTE working frequency band" information and "supported carrier aggregation working frequency band combination" information according to actual capabilities and standard support conditions; the network side according to the "supported LTE working frequency band" information The "working frequency band" information and the "supported carrier aggregation working frequency band combination" information jointly determine the carrier aggregation working frequency band combination capability actually supported by the terminal. Through the above solutions, the present invention can still provide a carrier aggregation service for a terminal that supports the combination and aggregation of a certain frequency band when the existing standard does not support the combination and aggregation of the frequency band.

Description

technical field [0001] The invention relates to a long-term evolution (LTE) system, in particular to a method and device for virtual mapping of frequency band support capabilities. Background technique [0002] The Ministry of Industry and Information Technology of the People's Republic of China approved China Mobile to carry out TD-LTE scale tests in 6 cities including Shanghai, Hangzhou, and Nanjing at the end of 2010. The test frequency is 2570-2620MHz, and the corresponding 3GPP international standard frequency band number is Band38 (LTE working frequency band For the number, please refer to the list of LTE working frequency bands in Table 1 below). Later, Beijing, Tianjin, Shenyang and other cities successively approved the TD-LTE expansion test based on Band38. In order to further support the development of the TD-LTE industry from the perspective of basic strategy, the Ministry of Industry and Information Technology issued the "Matters Regarding IMT Frequency Plannin...
