Problems solved by technology

[0006] For terminals that develop Band 38+Band 39 cross-band carrier aggregation capabilities based on Band 38 terminal capabilities, the hardware capability is capable of working on China Mobile's network, but since 3GPP does not have a Band 38+Band 39 radio frequency standard (and the current international Only my country uses Band 39 in the world, and other countries have no demand for Band 38+Band 39 aggregation, and there will be no demand for Band 38+Band 39 projects in the short term), so the terminal cannot perform the Band 38+Band 39 carrier aggregation network access test, and the terminal cannot The report supports Band 38+Band 39 aggregation capability, even if the report is reported, the base station cannot provide corresponding carrier aggregation services for it

Embodiment 1

[0093] 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

[0125] 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:

[0126] 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.

[0127] 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

[0161] The present invention will be further described below through a specific example including the behavior of the terminal and the network side.

[0162] In this example, it is assumed that the hardware capability of a certain terminal supports working on Band38 and Band 39, and supports carrier aggregation on Band39+Band 38, but the existing 3GPP standard does not support Band 39+Band 38 aggregation. Band 39+Band 41 aggregation is supported, so the existing technology cannot report the carrier aggregation capability supported by the terminal through the reporting message specified in the existing standard.

[0163] This example can be handled as follows on the terminal side:

[0164] 1. The terminal configures the terminal's "supported carrier aggregation working frequency band combination" information, the specific method is as follows:

[0165] 1) The terminal judges whether the carrier aggregation working frequency band combination it supports is supported by the exis...

Abstract

The invention provides a method and an apparatus for frequency band support capability virtual mapping. The method includes: according to the practical capability and the standard support condition, a terminal is configured with "virtual carrier aggregation work frequency band" information, "supported LTE work frequency band" information, and "supported carrier aggregation work frequency band combination" information; and a network side determines the carrier aggregation work frequency band combination capability practically supported by the terminal in a combination manner according to the "supported LTE work frequency band" information and the "supported carrier aggregation work frequency band combination" information. By employing the above scheme, according to the method and the apparatus, even the conventional standard does not support certain frequency band combination aggregation, carrier aggregation service can still be provided for the terminal supporting the frequency band combination aggregation.

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 Band 38 (LTE work For frequency band numbers, 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 Band 38. 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 Planning" in...
