Embodiment

The embodiment of the present application is by a kind of data transmission method is provided, radio network controller, and base station and mobile communication system, solved the lower technical problem of data transmission efficiency existing in prior art.

Technical scheme in the embodiment of the present application is for solving the lower problem of data transmission efficiency of above-mentioned existence, and general thought is as follows:

By add compressor reducer and decompressor in RNC and base station, Frame waiting for transmission is carried out to harmless correlation compression, make the data redundancy in Frame can be compressed, and then the Frame after transmission compression is to base station or RNC, so, base station or RNC decompress accordingly to the Frame receiving, and so far just can complete the transmission of data.So just improved the efficiency of transfer of data.

In order better to understand technique scheme, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.

One or more embodiment of the application be take and is applied in 3-G (Generation Three mobile communication system) as example describes, such as, WCDMA(Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)), TD-SCDMA(Time Division-Synchronous Code Division Multiple Access, TD SDMA), certainly, can also be other communication system, as long as comprise RNC, and base station, the application is not specifically limited.

As shown in Figure 2, in base station, 102 have the Iub interface of standard between the two with RNC103, are to meet the user's request day by day increasing, and the protocol extension function of Iub interface is fully utilized.In base station 102 and RNC103, originally just had a plurality of application layer protocols, the application is the agreement of further having added compression/de-compression.So, as shown in Figure 3, base station 102 comprises: compressor reducer 201, and decompressor 202, data collector 203, wherein, data collector 203 also comprises transmitting element 2031 and receiving element 2032; RNC103 comprises: compressor reducer 301, and decompressor 302, data collector 303, wherein, data collector 303 also comprises transmitting element 3031 and receiving element 3032.

The application one embodiment provides a kind of method of transfer of data, is applied in RNC103 as shown in Figure 3, can certainly be applied in other RNC, and principle is all the same, so take below RNC103, as example, introduces the method, and as shown in Figure 4, the method comprises:

S101: obtain the first data to be transmitted;

S102: set up data transmission channel between RNC103 and base station 102 after, the first compression method of all supporting based on RNC103 and base station 102, compresses processing to the first data to be transmitted, obtains the first data;

S103: the first data are sent to base station 102, make base station 102 to the first data decompression, to obtain second data corresponding with the first data to be transmitted based on the first decompression method, wherein, the first decompression method is the decompression method mating with the first compression method.

The downlink transmission process of data of take below describes as example, the downlink transmission process of the data of saying be here exactly by RNC103 to base station 102 processes that send data.

Incorporated by reference to Fig. 3 and Fig. 5, need to be to base station during 102 transmission data as RNC103, carry out S101, that is: the receiving element in data collector 303 3031 obtains other nodes in mobile communication system, such as mobile core network 104, first data to be transmitted of sending, said the first data to be transmitted is a Frame here, take in the present embodiment HS-DSCH data frame structure as example, certainly, also can be E-DCH Frame, or other data frame formats, the application is not specifically limited.

Next, carry out S102, that is:, after setting up data transmission channel between RNC103 and base station 102, the first compression method of all supporting based on RNC103 and base station 102, compresses processing to the first data to be transmitted, obtains the first data.

Specifically, both the first compression methods of all supporting of being determined by RNC103 and base station 102 compress the first data to be transmitted in compressor reducer 301, can be by the filling information compression in Frame, identical information bit in the Frame of front and back can also be compressed, the duplicate contents in the load part of Frame can also be compressed.Through above-mentioned compression, obtain the first data, said the first data are also a Frame here, after the application, said the first data are all Frame.If the first data to be transmitted is because data frame content is filled, so, there is redundancy, such as, inserted 10 " 0 ", so, in the data frame content of the first data after compression, just there will not be this 10 " 0 ", or occur being far smaller than 10 several " 0 ", certainly, can also be other situation, the application be not specifically limited.

In specific implementation process, to the compression of the first data, can adopt the lossless compression method of single frames, such as Run-Length Coding, single frames lossless compression method is with whether packet loss is irrelevant, but compression ratio is lower.In order to reach better compression ratio and to realize more efficient transfer of data, can adopt harmless relevant compression method to compress the first data to be transmitted, compression method can be encoded for Shanno-Fano, Huffman (Huffman) coding, LZW coding, arithmetic coding etc., that is to say that the previous frame Frame to having transmitted puts into compressed buffer, by the first data to be transmitted only transmit with the difference part of the previous frame Frame having transmitted and with position and the length information of going up a Frame same section.HS-DSCH Frame as shown in Figure 6, the data that " MAC-d PDU Length " started are just sent into compressor reducer 301 and are compressed; Again as shown in Figure 9, the 3rd byte E-DCH Frame being started from frame header can just be sent into compressor reducer 201 and compress; Certainly can also have other compress mode method, as long as can reach harmless compression and reliable transfer of data, those skilled in the art can set voluntarily, and the application is not specifically limited.

In specific implementation process, as shown in Figure 5, before S102, method can also comprise:

S201: 102 send the first solicited message to base station, wherein, carry the first list of compression methods that RNC103 supports in the first solicited message;

S202: obtain the first response message generating based on the first solicited message being sent by base station 102, wherein, the first response message carries the second list of compression methods that method base station 102 is supported;

S203: based on the first list of compression methods and the second list of compression methods, obtain the first compression method.

Specifically, transmitting element 3031 is 102 transmission the first solicited messages to base station, this first solicited message comprises the first list of compression methods of all compression methods that RNC103 supports, next, at the receiving element 2031 of base station 102, receiving after above-mentioned the first solicited message, based on this first solicited message, generate the first response message, specifically, the first compressed list that the second list of compression methods of all compression methods of for example base station 102 being supported is added in the first list of compression methods information and the first solicited message is added in the first response message together, or only add the second list of compression methods in the first response message, then, by transmitting element 2032, send to RNC103, receiving element 3032 can receive this first response message, further, the compressor reducer 301 of RNC103 can, according to compression method information entrained in the first list of compression methods and the second list of compression methods, be selected the first compression algorithm that RNC103 and base station 102 are all supported.

For example, RNC103 supports compression method A, B, C, D, so, RNC103 will add the first list of compression methods that comprises these four kinds of methods in the first solicited message to, then, sends to base station 102, base station 102 is after receiving the first solicited message, if compression method A, B are supported in base station 102, C, so, base station 102 will be added on the second list of compression methods and the first list of compression methods that comprise these three kinds of methods in the first response message, then, send to RNC103.RNC103 selects according to above-mentioned two lists of compression methods the compression method that RNC103 and base station 102 are all supported again, can be A, can also be B, can be also C, as long as RNC103 and base station 102 all support, the application is not specifically limited.

Pass through S201-S203, the mutual of compression method carried out in RNC103 and base station 102, which the compression method that the clear and definite the other side of both sides can be supported has, and therefrom select a kind of, for notifying opposite end in the user's bearing link process of establishing follow-up, can also make in follow-up compression process, reduce and because compression method does not mate with decompression method, produce mistake or abnormal probability, realized reliably, efficiently transfer of data.

Further, because every kind of compression method is all different to the demand of system resource, so, a certain compression method can be supported according to current system resource in base station 102, so, for the compression method of further determining that RNC103 and base station 102 current times are supported, before S102, as shown in Figure 5, method can also comprise:

S301: 102 send the second solicited message to base station, and wherein, the second solicited message carries the first compression method;

S302: receive the second response message generating based on the second solicited message being sent by base station 102, make to set up data transmission channel between RNC103 and base station 102, wherein, the second response message carries the second compression method of base station 102 current supports;

Specifically, transmitting element 3031 is 102 transmission the second solicited messages to base station, wherein, the second solicited message carries the first compression method, and then, base station 102 is after receiving the second solicited message, the second compression method of own current support is added in the second response message, and sending to RNC103, receiving element 3032, after receiving the second response message of being sent by base station 102, is set up data transmission channel between RNC103 and base station 102.

Such as, the first compression method is A, if current base station 102 is supported compression method A, so, in the second response message just with the information of method A; If current base station 102, because load just may be supported A too greatly, still can be supported B, so, base station 102 will be added on the information of compression method B in the second response message.Like this, just between RNC103 and base station 102, set up data transmission channel.Be data downstream transmission channel in the present embodiment.

In specific embodiment, S201-S203 can carry out before S301-S302, but when a kind of compression method is clearly only supported in RNC103 and base station 102, just need not carry out S201-S203.

In another embodiment, owing to obtaining the second current supported compression method of base station 102 in S302, S102 is specifically as follows so: judge that whether the first compression method is consistent with the second compression method; When the first compression method when consistent, is used the first compression method to compress the first data to be transmitted with the second compression method, obtain the first data.

Specifically, the compressor reducer 301 of RNC103 judges that whether the first compression method is consistent with the second compression method, the first compression method of selecting as RNC103 is A, and the second compression method of base station 102 current supports is while being also A, so, RNC103 will adopt method A to compress the first data to be transmitted.

Further, after S302, method can also comprise: judge that whether the first compression method is consistent with the second compression method; When the first compression method when different, directly sends the first data to be transmitted to base station 102 from the second compression method.

Specifically, the compressor reducer 301 of RNC103 judges that whether the first compression method is consistent with the second compression method, the first compression method of selecting as RNC103 is A, when the second compression method of base station 102 current supports is but B, so, RNC103 does not just compress processing to the first data, but by not compressing the first data to be transmitted of processing, directly sends to base station 102 by transmitting element 3031.

After obtaining the first data by S102, carry out S103, that is: the first data are sent to base station 102, make base station 102 to the first data decompression, to obtain second data corresponding with the first data to be transmitted based on the first decompression method, wherein, the first decompression method is the decompression method mating with the first compression method.

Further, if base station 102 1 sides decompress, occurred problem, in order not interrupt the transmission of data, as shown in Figure 5, method also comprises:

S401: receive the decompression abnormal information being sent by base station;

S402: based on decompression abnormal information, control wireless system controller and enter non-compressed mode transmission, make wireless system controller in upper once data transmission procedure not adopt the first compression method to compress the second data to be transmitted.

Specifically, in base station, 102 1 sides have occurred to decompress abnormal, that is to say generation de-compression failure, or during the situations such as the first corrupted data, in order not affect ensuing transfer of data, RNC103 can receive the decompression abnormal information being sent by base station 102, next, RNC103 will be according to the above-mentioned decompression abnormal information of receiving, control and self enter non-compressed mode transmission, here said non-compressed mode transmission is carrying out the second data to be transmitted exactly, while being the transmission of next frame data, compressor reducer 301 is not enabled the first compression method the second data to be transmitted is compressed.In specific implementation process, not adopting the first compression method can be to adopt the compression method that is different from the first compression method to compress the second data to be transmitted, can also be that the second data to be transmitted is not compressed, just directly send to base station 102, certainly, can also have other mode, those of ordinary skills can set voluntarily, and the application is not specifically limited.
