Embodiment one
The control method of the original state message of the present embodiment, as in figure 2 it is shown, comprise the following steps:
Step S101: compression end equipment sends original state message to solving pressure side equipment；
In this step, compression end equipment learn be not synchronized to contextual information between solution pressure side equipment and he time, just send original state message to solving pressure side equipment, this original state message is for carrying out foundation and the synchronization of context.Concrete, access original state message dropping maybe when sending switching when normal, send original state message to decompression.Such as, being switched to another one community from a community, at this moment often target cell base station is not synchronized to contextual information corresponding to this UE, is now necessary for being re-established by transmission original state message and being safeguarded.It should be noted that, if in handoff procedure, target side is synchronized the ROHC contextual information of source, so after being switched to target side community, this transmission content can not be used, do not send initial IR message and carry out the synchronization of contextual information, in original state, directly send efficient compressed packet.At some in particular cases, during as normally accessed, the situation of initial IR packet loss occurs, it is also desirable to re-establish by sending original state message and safeguard.It is construed as compression end equipment and solves pressure side equipment and original state message feedback previously established has been got well feedback link carrying out, as long as being construed as this feedback link for allowing compression end equipment communicate with solving pressure side equipment, pressure side equipment to be solved and can tell that the link of situation that compression end equipment receives original state message can by this link.Concrete foundation can be before compression end equipment sends original state message, it is also possible to is after sending original state message, it is understood that as long as feedback link existence all can realize before solving pressure side equipment feedback original state message.Preferably, hybrid automatic repeat-request feedback link is set up between compression end equipment and solution pressure side equipment, owing to the transmission of existing original state message is unidirectional mode, and compression end equipment conciliates pressure side equipment all in above high-rise link layer, there is no direct feedback link, cannot learn whether the original state message solution pressure side equipment sent receives, and is not easy to the quantity forwarded of original state message is controlled.Conciliating hybrid automatic repeat-request feedback link between pressure side equipment bottom physical layer by setting up compression end equipment, the original state message that solution pressure side equipment receives compression end equipment feeds back.
Step S102: compression end equipment receives and solves the original state message feedback information that pressure side equipment is sent by the feedback link pre-build with it；
In this step, feedback information is construed as solution pressure side equipment and tells that compression end equipment specifically receives the information of original state message, and the bottom physical layer of solution pressure side equipment have received the original state message of compression end equipment transmission and just feeds back the original state message information received.Such as, compression end equipment have sent 10 original state messages, and solve pressure side equipment and have received 9, is just fed back the feedback information of 9 original state messages by hybrid automatic repeat-request feedback link.Preferably, this feedback information includes ACK information, if being namely properly received an original state message just one ACK information of feedback.Such as above-mentioned example, just 9 ACK information of feedback.

Step S202: solve pressure side equipment by arranging the original state message of the feedback link transmission of foundation in advance with compression end and feed back to compression end equipment.
In this step, it is understood that before the feedback information of feedback original state message, just established feedback link.Preferably, set up and hybrid automatic repeat-request link between compressor, send the hybrid automatic repeat request feedback information of original state message to compression end equipment by hybrid automatic repeat-request link.
Further, after above-mentioned steps S201, namely also include after receiving the original state message that compression end equipment sends: send ROHCACK and feed back to compression end equipment, namely compression end equipment has had built up contextual information synchronization, need to carry out the Efficient Compression Message processing of advanced compression pattern, just tell that the change that compression end carries out pattern need not send out original state message again.Such as, setting predetermined threshold value K, after being switched to target side, the initial pattern of ROHC example is U (Unidirectional, unidirectional) pattern, while sending initial IR message in u mode, follow the tracks of the HARQ feedback information of message, it is assumed that while have sent the initial IR message of M bag, the HARQACK quantity receiving correspondence has reached threshold value K, so now can select to stop sending IR message, transition high state, send Efficient Compression message；If solving pressure side during this period and having triggered to O (Optimistic, preferably)/R (Reliable, pattern switching reliably), and compression end have received and solves the ROHCACK feedback that pressure side is beamed back, so same stopping sends IR message, carry out pattern switching, state transition, send Efficient Compression message.
The control method of another original state message of the present embodiment, as shown in Figure 4, comprises the following steps:
Step S301: compression end equipment sends original state message to solving pressure side equipment；
Step S302: solving pressure side equipment and receive solution original state message, the original state message sent by the feedback link set up with compression end equipment in advance feeds back to compression end equipment；
