In this article; Such as a left side with right, first and second, relational terms preceding and back only is used for an entity or action are made a distinction with another entity or action, and be not necessarily require or hint this entity or move between actually have any this relation or in proper order.Term " comprises ", " comprising " or its other variation is intended to cover comprising of a kind of non-exclusionism; Make that thus the processing, method, goods or the equipment that have comprised a series of key elements not only can comprise these key elements; But also can comprise other key elements of clearly not enumerating, or be these processing, method, goods or equipment intrinsic other key elements.Under the situation that do not having much more more restrictions, the key element that is limited by " comprising ... " also is not precluded within processing, method, goods or the equipment that has comprised this key element and also has other identical element.

According to conventional TCAP signaling,, and use it for affairs of sign for each tcap query has distributed a numeral.Then, identical digital copies in response message, is associated with response message thereby can make to inquire about.The TCAP coding has used a kind of reference format of in the specific composition part of TCAP message, inserting specific type of data.Call (invoke) part and describe a particular request, and identify the action of being asked.The response part then is used to return the data of being asked.The mistake part is when the reply data storehouse has enough information to come inquiry made response, not use.At last, when the reply data storehouse confirms to fulfil inquiry, use the refusal part.

With reference to figure 2, block diagram has wherein been described conventional TCAP signaling message form 200.Message format 200 has comprised Message Signal Unit (MSU) header 205, message transmission protocol (MTP) part 210, spare bit 215, SCCP (SCCP) 220, TCAP part 225 and MSU afterbody 230.In TCAP part 225, used mark to identify different messages part mentioned above.For example, before the mistake part is covered TCAP part 225, a mark will be set, so that state this mistake part.Then, how long fields will be described the error code that is comprised has.At last, another field will identify the reason of mistake.

In up-to-date 3G WCDMA (CDMA) wireless communication system, in MAP (MAP) message, still used the TCAP message format of routine mentioned above.Yet this system has comprised too much new business, for example multi-rate speech calling, video call and various supplementary service.In addition, concerning 3G WCDMA system, its number of users is in quick growth.Therefore, compare with previous 2G global system for mobile communications (GSM), the relative populations of the MAP signaling message in the 3G WCDMA system has had remarkable lifting.If the quantity of MAP message has surpassed power system capacity, the data of higher priority will be pushed MAP message open so, stop MAP message to carry out its appointed function thus.

With reference to figure 3, block diagram has wherein been described the TCAP signaling message form 300 through revising according to the embodiment of the invention.Similar with the TCAP signaling message form 200 of routine, message format 300 has comprised MSU header 305, MTP part 310, spare bit 315, SCCP part 320 and TCAP part 325.Yet different with the message format 200 of routine, according to one embodiment of the present of invention, message format 300 has comprised optional Invoke ID (the calling ID) parameter 330 that is in place, fixed position predetermined in the message.According to message format 300, optional Invoke ID parameter 330 is in last byte of TCAP message.Then, MSU afterbody 335 is followed the back in optional Invoke ID parameter 330.

According to embodiments of the invention, in the 3G wireless communication system, Invoke ID (calling ID) parameter 330 can significantly be improved the treatment effeciency of TCAP message.This be because; According to existing third generation partner program (3GPP) standard, conventional Invoke ID parameter---owner of this parameter identification MAP message and be used in thus in the process of following the trail of MAP message---is not anchored on place, fixed position predetermined in the conventional TCAP message format 200.In contrast, in the TCAP of routine message, can before the Invoke of routine ID parameter, insert various optional contents.The station that this means the conventional TCAP message of reception must be searched for whole message by turn, so that confirm the position of conventional Invoke ID parameter.In addition, conventional Invoke ID parameter must be located by each network station that receives TCAP message, so that make each station can both determine whether to be necessary to take any action based on this message.The TCAP message of therefore, searching for this routine will consume the processor resource of great amount of time and 3G system.

According to one embodiment of the present of invention, optional Invoke ID parameter 330 is positioned at place, predetermined fixed position with respect to MSU header 305.This means that tracing system needn't be located optional Invoke ID parameter 330 through searching for whole message by turn when receiving the TCAP message of the TCAP message format 300 that has used the process modification.On the contrary, tracing system can identify predetermined fixed position immediately, and reads optional Invoke ID parameter 330.Consider that 3G WCDMA system will handle millions of TCAP message, the present invention can practice thrift considerable system resource thus.

The supplementary features of the application of the invention can be with accordinging to conventional TCAP signaling message form 200 by the formatted message executable operations by formatted message according to the TCAP signaling message form 300 of process modification.These supplementary features are through the format identifier of revising, and this identifier shows that Invoke ID parameter is in the place, predetermined fixed position in the TCAP message.In addition, can be in the place, predetermined fixed position in the TCAP message equally through the format identifier of revising.According to one embodiment of the present of invention, spare bit 315 is used to store this format identifier through revising.

For example; In the system that uses through the TCAP signaling message form 300 revised and conventional TCAP signaling message form 200; When certain station received through the TCAP signaling message form 300 revised, this stands in and does not identify what use in the TCAP message that receives at the beginning was for which kind of form.Yet, if spare bit 315 has comprised the format identifier through revising, numeral " 01 " for example, it show said station needn't be in whole TCAP message Searching I nvoke ID parameter; On the contrary, Invoke ID parameter is read in the place, predetermined fixed position in TCAP message immediately in said station.

According to different embodiments of the invention, the predetermined fixed position of optional Invoke ID parameter 330 can be any position in the TCAP message.As long as this position is anchored at through on certain part of the TCAP signaling message form of revising 300, the for example MSU header 305; Optional Invoke ID parameter 330 just can located and read in the station that receives the TCAP message of the form of revising according to process 300 immediately, and needn't search for whole TCAP message.
