Abstract

The present invention discloses an operation code identification method and an operation code-based short message signaling interception method, which can accomplish operation code identification and interception on a Signaling Connection Control Part (SCCP) layer. The interception method includes: the Message Transfer Part layer transmits an SCCP layer data packet; the SCCP layer disassembles the received SCCP layer data packet to obtain a Transaction Capabilities Application Part (TCAP) data packet from the Unit Data; the SCCP layer decodes the TCAP data packet to obtain an operation code field of the service information in the component portion (CP) information unit, and identifies whether the operation code in the operation code field is the preset target operation code to be intercepted; if so, the SCCP layer performs the signaling interception. The invention increases decoding efficiency and reduces system overhead. Moreover, the signaling identification and interception method provided by the invention performed according to the operation code may also be combined with the global title (GT) routing function of the SCCP layer, to enable short message signaling interception according to different GT numbers.

Description

Opcode method and opcode-based message order method

Wood field

This covers messaging and various areas, especially with regard to operational methods and operation-based message order methods.

Background

In addition to the various, bearer and each, the common ground (P N ) can provide users with convenient and effective information communication means and each. The messages each enable very small terminals to receive or receive text messages of limited length by means of , and so on, with the message content directly above.

The news is of great importance. The order is the wood of modern communication, the idea of separation according to the system ( ) and the common system of use.

The order of the message is up, and the component of the message (TP), the connection control part (SCC), the capability part (TCA), and the part (L) are mostly used. The first three parts of the order, the management, the interface, and the part of the message and the function of each phase.

The news is mainly divided into strengths and small and small. And each of the users in the system can have a message, but need to pass the message (S).

The messages are each composed of basic and separate messages (messages, -) and sheep, receiving messages (messages, S-) and each of the sheep and the news (in the news, -Ae) and the sheep. The message and the message of each sheep are processed by the flow (R), that is, the routing address of the message to the location register (R) (that is, the address of C in each user's exchange), and then the message can be sent to C. Looking at the news and not both inside and outside, because of the same, different, terminal status and value-added, each new demand is not raised. In the message and in each requirement, there is an order that needs to be sent to the message for some reason.

In this regard, this book proposes new ways to operate.

Content

To solve the existing wood, the method of operation and the operation-based message order method can be completed in the CCP part.

This provides a message order method for operation, including

The signalling connection control part receives the received message. Some of the friends make the connection control department separate and disassemble, and the sheep position teaches each ability to teach.

The signalling connection control part of each part uses the number of lines to solve the problem, and the operation of each piece of information and the operation of each piece of information, the operation of the operation, is the order.

The steps to be operated include the length and positioning of the information sheep.

The steps of each ability to teach and solve

In the signaling connection control part, the first pointer and the second pointer are pointed, the first pointer points to the user part, and the second pointer points to the tail of the user part.

The first pointer is the length and length of the information sheep, and locates the content of the information sheep.

Pass the pointer.

, is the first indicator of the length and length of the information sheep in the order.

The method includes the integration of the signaling globally by functions. At the beginning, according to different global message orders.

In the part of the message that the connection control part receives, the step of dismantling the connection control part includes the pre-operation, which is configured on the special connection to the global in the message.

Integrating the global signaling function into the steps of different global message commands

If the operation in operation is performed, and the global in the signaling of the message part is the global to the message, the signaling is specially connected to the message of the message.

The method of operation is provided, including

The part of the signalling connection control is used to solve the problem. It is necessary to complete the operation of each part of the information and the operation of the information.

The steps of each ability to teach and solve

In the signaling connection control part, the instruction has a deciphering pointer and a second pointer, the first pointer points to the user part, and the second pointer points to the tail part of the user part.

Pass the pointer.

Compared with the existing wood, the wood plan of this book goes up to the CCP, The user part of the sheep teaching (T) is not complete, which improves the efficiency of understanding and reduces the system. In the case of the CCP, the message is no longer uplinked, and the TCA and signaling are alleviated, improving the efficiency of the system. In addition, the proposed signaling method can be combined with the global (GT) function of SCCP, and it is more useful for different GT message commands.

1 is the flow of the existing wooden message order

2 is the message order and process flow proposed by the present

3 is the flow of the message in the message

4 is a schematic diagram of the combination of the signaling GT functions of the present invention.

The preferred way of this

In the following, the method of explaining the wood and the wood can be fully understood by combining the method and the detailed description.

Separate and separate, so that the signaling information required for the residence can be received or signalled, and the information that does not need to be understood can be directly encapsulated.

.

Messages, , and by news, etc.

The operation, and the use of each. So, fruit

Someone who ordered the news

. However, if it will be different, then let it go straight up to

If there is more type of signaling required, it will inevitably increase and each of them will occupy more resources, which will be larger and lower the efficiency. 1 is the flow chart of the existing wooden message order. In accordance with the order of the order, each of the friends sent to the message, followed by the message (TP), the connection control (SCC), the capabilities (T) and

( ), the most and the rest of the news and each. Because of the information of the order of the sub-prefecture, the signaling content contains the most information and the information of each interface is included in the information, and each information is contained in the component part of T. The information is included in the CCP. The TC is included in the CCP. The sheep position teaches (T) the user, the CCP contains the signaling information (F) of the TP message sheep ( ).

As shown in Figure 1, the message order in the existing wood mainly includes the following steps, and the TP receives the message from the friends.

Step 120, the TP message is disassembled, and the message is obtained from the CCP CCP.

Step 0, SCCP dismantling, T-study gets T

T

Step 140, T T disassemble, the component part information information obtained in the sheep step 15 , and each information line is solved to obtain phase information, and then each interface.

The general process of the message order is to make the message parsing up to

And for each piece of information, if you do not want to operate one of the desired operations, then the message. And the information is complete, that is, every medium must be, it is a very resource-intensive work.

2 is the message order and process proposed by the firm. 2, the signaling and interception process of this section mainly includes the following steps.

Step 210, the same step 0

Step 220, the same as step 120 Step 230, SCCP dismantling, sheep get T

, T line solution, get the information of the component part of the sheep and the operation of each information, whether the operation value of the operation is the expected operation in advance, if it is the ratio, if not, then T T , .

Thus, the message goes up to the CCP, and the CCP goes to the operation of the sheep (T). If it is a pre-operation (operation of the message), then the message, and .

The difference between the above process and the existing wood shown in 1 is that the solution in the present invention is incomplete, and the other is to locate the operation, and the others

Therefore, the solution in the existing wood shown in Figure 1 is more efficient. In addition, since the message is not in the CCP, the signalling of T and is completely reduced, which improves the efficiency of the system.

3 is a schematic diagram of the flow of the message and the method in the message. 3, mainly including the next steps

Step 310, receiving an external operation, which is a desired operation, is the operation of the message.

Step 320, in each of the TP friends, the user part of the CCP T sheep, the length of the user part, and the operation of the message order

Step 5330, the first pointer and the second pointer respectively point to the part and the tail of the user part, and refer to T, the first pointer of the pointing direction locates the length, the content and the content of each information sheep, and the second pointer to the tail is in the line Cross-border in solution

Referring to T, the message exists only in the (Beg) message or (o) message, and other types of T messages can be no, so the information can be sheep and the length is fast.

Reference, Beg messages must contain origins (original 0x48) The Co e message contains both the origin and the destination (0x49 of the purpose). Therefore, the first pointer needs

Refer to Yes, the part is ok (partial 0x6B), so if the message has a part, the first pointer needs

Step 340, the first pointer to the component part (0x6 of the component part), according to the voke component type, gradually shift the first pointer to the operation, and do not perform the operation.

In step 350, the external operation of the operation is compared, and the result is obtained, that is, the request is not required.

The solution in step 320 is the operation of the order, and the rest of the content is not, so in the line like the existing wood, the group that only needs to follow, the pointer is quickly applied to the operation of the component part, so that the operation can be performed. Part of the Vision CCP user can be incomplete.

The CCP user part in step 320 above is the encapsulation of T. The study of T can be, the message of T is composed of information sheep, and the information is divided into three parts: the weight, the length (e h) and the content ( o e ). Therefore, the solution in step 320, the length and length of the information sheep can quickly locate each content.

Step analysis T can, T consists of mesons, namely each sub- and component. Each child "T user" is exchanged with the message containing the component, the component of the component, that is, the operation and the sheep.

Ingredients have components and parts. In the message-containing sheep teaching (T), most of them contain component parts, but they do not contain parts, and they operate.

In the component part, therefore only the component part analysis is required, and the operation can be performed. It should be noted that the T package is not fixed. Information sheep is ok, some information sheep are not necessarily different, the length of the information sheep may also be indefinite, they are all in need of attention, so need Dange T And algorithm line solution.

Existing xyco, CCP has a major function, which is to provide global (GT) routing functions, which can make the global interconnection of different orders directly. Since the proposed signaling operation and the function of the command are in the CCP, it is possible to integrate the function and the GT function, and to function according to different GT message commands.

According to different GT message commands, the function is very high, and the function is larger than that of the sheep. Because in the demand, the user often does not want to pull all the signaling, but hopes that Signaling to the order. Therefore, in the case of God, we can integrate the functions proposed by the CCP with the GT functions of the CCP itself to meet the needs of users.

Dong said that the message order is the GT function of the CCP will be sent to each message, if you need to send the order to the message, but not sent to other messages, this can be used in the GT of the message , the configuration of the operation, stronger.

4 is a schematic diagram of the combination of the signaling GT functions of the present invention. 4, this mainly includes the following steps

Step 410, configuring the GT of the A in the message on the special connection (TP), and the operation of the same configuration (the operation refers to the operation)

The order needs to make the special connection (TP) from the message to the middle of the message, only the order from the A to the message, and the order to the other message as usual, then the special connection, the configuration is from the message A. GT, just the same operation as the configuration

Step 420, comparing each of the TP friends, in the CCP GT and the same, using the proposed operation method, comparing the pre-operations of the operations Whether the GT in the previous order is configured to route to the GT of the message A, to the operation of the previous operation,

If all are satisfied, then the special step 43 is at least not satisfied, then the special step 44 step 43 is to make the match, the TP will be ordered, so it is not sent to the message A,

Step 44: If the order is not met, it means that it may not be ordered, or it may be caused by not the message, A, but other messages, so it is not necessary, TP often signaling.

The wood solution provided in this is the user part of the CCP CCP (ie, the package of T) is fast and incomplete, and the operation of the rapid positioning is enabled, and the message can be reduced.

The rabbit takes up more resources and improves the efficiency of the system. In addition, the technical solution of the present invention can be combined with the GT function of the CCP, depending on the function of the different GT messages. This wood scheme can be used in addition to other multi-issue processes in the order of the ordering process.

The above is better than the rest of the way, but the protection of this is not limited to this. Any wood that is familiar with wood can be easily imagined or replaced in the wood garden disclosed in this disclosure.

Usability

Compared with the existing wood, the wood scheme of this book goes up to the CCP, and the user part of the sheep teaching □J T) is incomplete, which improves the efficiency of understanding and reduces the system. In addition, the technical solutions of the present invention can be combined with the CCP's GT functions, depending on the GT's message order function.
