Abstract
Abstract In the initial analysis or forming of a signalling message (sm) having a message header (MK) and information elements (IE) appended thereto (for example according to CCITT recommendation Q.93B), the signalling message (sm) is buffer-stored in a buffer store ZSP to information items (ti, ki) defining the information element type and the initial addresses (sia, csia) of the information element-specific information items stored in the buffer store ZSP are entered using of an address generation routine (AGR) into an auxiliary address store (HAS). An indicative information item (hi) is transmitted to the further processing routines (WR), indicating the existence of an auxiliary address store (HAS). The buffer-stored information items (ti, csi, si) of the signalling message (sm') can be retrieved using a retrieve routine (ABR) and the auxiliary address store (HAS) by the further processing routines (WR). The process makes it possible to retrieve the buffer-stored information items (ti, csi, si) of the information elements (IE) of a signalling message (sm) to be analyzed or of a generated signalling message (sm) with rapid access, either repeatedly or, in particular, only partially.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
139 words
A process for forming and analyzing signalling messages in a program-controlled communication device, the signalling messages having a message header and information elements appended thereto, defining an information element type and having information element-specific information items, comprising the steps of: setting up, for each signalling message to be analyzed or formed for a first time, a buffer store for storing a signalling message, and an auxiliary address store for storing buffer store addresses; defining and entering, on an information element basis into the auxiliary address store, using an address generation routine the information items that define a respective information element type and initial addresses of the information element-specific information items that are buffer-stored in the buffer store; transmitting an indicative information item that indicates the existence of an auxiliary address store to further processing routines of the communication device.
Claim 2
Dependent Claim
139 words
A process for forming and analyzing signalling messages in a program-controlled communication device, the signalling messages having a message header and information elements appended thereto, defining an information element type and having information element-specific information items, comprising the steps of: setting up, for each signalling message to be analyzed or formed for a first time, a buffer store for storing a signalling message, and an auxiliary address store for storing buffer store addresses; defining and entering, on an information element basis into the auxiliary address store, using an address generation routine the information items that define a respective information element type and initial addresses of the information element-specific information items that are buffer-stored in the buffer store; transmitting an indicative information item that indicates the existence of an auxiliary address store to further processing routines of the communication device.
Claim 3
Dependent Claim
126 words
The process as claimed in claim 1, wherein the information item defining the information element type is represented by a type information item and the information items defining the information element-specific information items are represented by signalling information items, wherein, the auxiliary address store has an information element store which is assigned to each information element wherein a linking information item defining the linking of the information elements is entered into a linking store area of the information element store, wherein the type information item is entered into a type store area of the information element store, wherein the initial addresses of the octet-oriented groups of signalling information items stored in the buffer store are stored into signalling information store areas of the information element store.
Claim 4
Dependent Claim
57 words
The process as claimed in claim 1, wherein an information element-specific information item is represented by a code record information item indicating the current message record, and wherein there is entered into a code record store area of the respective information element store the initial address of the code record information items stored in the buffer store.
Claim 5
Dependent Claim
38 words
The process as claimed in claim 1, wherein the linking information item is formed by an information item indicating a last information element of a same type or at least a following information element of a same type.
Claim 6
Dependent Claim
110 words
The process as claimed in claim 1, wherein there are stored in a test memory structure, for each type of signalling message and the information elements contained therein, signalling protocol-conformal protocol information items according to a currently provided signalling protocol, wherein, following entry of the information items into the auxiliary address store, the information items of the buffer-stored signalling message are compared on an information element basis with the entered protocol information items of the test store structure using a checking routine and the auxiliary address store, and error information items are entered into an error indication store if signalling messages do not conform to the protocol or are incomplete.
Claim 7
Dependent Claim
30 words
The process as claimed in claim 1, wherein the information items of the signalling message are retrieved by further processing routines using a retrieve routine and the auxiliary address store.
Claim 8
Dependent Claim
55 words
The process as claimed in claim 1, wherein, when forming signalling messages, further information element routines and the address generation routine are used to supplement the signalling message stored in the buffer store by further information elements and in the set-up auxiliary address store by further information items which are entered into information element stores.
Claim 9
Dependent Claim
30 words
The process as claimed in claim 1, wherein, for a setting up or clearing of a buffer store and an auxiliary address store, a setting-up and clearing routine is provided.
Claim 10
Dependent Claim
35 words
The process as claimed in claim 1, wherein, using a message header routine, the message header information items, contained in the message header of a signalling message, and also the error information items are controlled.
Claim 11
Dependent Claim
24 words
The process as claimed in claim 1, wherein the signalling messages and their information elements are structured according to CCITT recommendations Q.931 and Q.93B.
