Description
Technical field
The present invention relates to the communications field, in particular to a kind of data message processing method and device.
Background technology
PDCP (Packet Data Convergence Protocol abbreviates PDCP as) belongs to a sub-layer of layer 2, only is applied to the PS territory.The PDCP sublayer will be accomplished the header suppression of execution IP traffic and the function of decompression respectively in transmission and receiving entity.
Robustness head compression (Robust Header Compression abbreviates ROHC as) agreement is a kind of compression method that can be under the channel condition of extreme difference RTP/UDP/IP packet header be compressed to a byte.Wherein, comprise RFC3095, RFC3843, RFC4995, RFC4996, RFC4815, RFC5225 agreement.
The principle of ROHC head compression is that the RTP/UDP/IP head is divided into static part and dynamic part.In the process of transmitting of data, compression end and decompress(ion) end are preserved the static part of data separately, only send dynamic part.After simplifying, the dynamic part that finally need send for the RTP head comprises three: IP identifier (IPID), the sequence number of RTP (SN), the timestamp of RTP (TS).
For IPID two kinds of production methods are arranged: add 1 and increase progressively and generation at random.For adding 1 method that increases progressively, can deduce out the IPID of next bag according to the IPID of a last bag, thereby can reduce the figure place that transmits IPID even do not transmit IPID just can be at the numerical value of decompress(ion) end recovery IPID.And for the IPID that produces at random, owing to there is not rule, therefore, be merely able to IPID is sent fully.Therefore, the producing method of judgement IPID has important function for compressed IP ID.In correlation technique, judge that the producing method of IPID mainly contains following two kinds of processing modes:
(1) difference of the IPID of front and back two bags of the same context of use is judged.In ROHC, context is used for preserving static part and the dynamic part of RTP/UDP/IP, after successfully receiving a bag, the dynamic part of this bag is upgraded, as the reference of next bag.Judge whether it is same context, confirm that the bag type is different, and the static part difference of same package type all is regarded as different context through the static part and the bag type of preserving among this context.
Fig. 1 is the structural representation of judging the IPID producing method according to the IPID of the front and back of using same context in the correlation technique two bags, and is as shown in Figure 1, RTP0, RTP1, RTPN-1, RTPN, expression be the 0th bag of receiving, the 1st bag, N-1 bag, N bag; IPID0, IPID1, that IPIDN-1, IPIDN represent is the IPID in the corresponding RTP bag.
In context, store successfully receive on when bag; The IPID of a bag on this is designated as A (IPID); When next when bag that receives this context, the IPID of this next bag is designated as B (IPID), use B (IPID)-A (IPID); When this is worth greater than a constant N, think that then IPID produces at random.N is a constant.From in essence, be to use the difference of the IPID that wraps with a kind of front and back two of wrapping type to judge.
(2) difference of IPID and SN is judged in the same RTP bag of use.Fig. 2 is the structural representation of judging the IPID producing method according to the difference of IPID and SN in the same RTP bag of use in the correlation technique, and is as shown in Figure 2, Packet0; Packet1, packet2 ... .packetN (bag 0 wraps 1; Bag 2.... bag N), expression ENB is actual which bag of receiving.RTP0, RTP1, expression ENB receives which bag of RTP bag.UDP0, UDP1, expression ENB receives which bag of UDP bag.In RTP, the increasing according to the order of sequence of the growth of SN, the value that the IPID of this bag is deducted SN obtains difference A, if this difference A when IPID in the last data bag equates with SN difference B, thinks that then IPID adds 1 and increases.Essential and above-mentioned (1) kind mode is identical.
Adopt two kinds of above-mentioned processing, do business sheet for the moment, can judge the growth pattern of IPID for UE.Do under the situation of multiple business but work as UE, above-mentioned two kinds of methods all deviation can occur, cause compression efficiency low.Planting processing mode with (2) is that example describes: in Fig. 2; Words according to the context division; RTP packet and UDP message bag belong to two context; Overstriking not the italic font represented be the IPID of context (context) storage of RTP, not overstriking italic font representation be the IPID of the context storage of UDP.Suppose that present IPID growth pattern is to add 1 to increase.Simultaneously between RTP1 and the RTP2 at interval greater than N UDP message bag, have IPID N-1 – IPID1 according to the calculating of present different context this time>N.Thereby think that according to judging the growth of IPID is a random increase.Therefore, IPID is all sent, do not compress.
Therefore, in correlation technique, exist processing of data message and the low problem of IPID compression efficiency.
