| |
| = Functionality |
| |
| The MobileL3 v13.4.0 protocol module implements the message structures of the related protocol <<_5, [5]>> in a formalized way, using the standard specification language TTCN-3. This allows defining of test data (templates) in the TTCN-3 language and correctly encoding/decoding messages when executing test suites using the Titan TTCN-3 test environment. |
| |
| The MobileL3 v13.4.0 protocol module uses Titan’s RAW encoding attributes <<_1, [1]>> and hence is usable with the Titan test toolset only. |
| |
| == Implemented Protocols |
| |
| This set of protocol modules implements a subset of protocol messages and constants of the Mobile L3 protocol. It includes GMM, SM, RRM, SMS and SS. SM and GMM are based on 24.008 v13.4.0 (see <<_4, [4]>>), RRM are based on 44.018 v13.0.0 (see <<_5, [5]>>), SMS are based on 24.011 v13.0.0 (see <<_6, [6]>>) and 23.040 v13.0.0 (see <<_7, [7]>>) and SS are based on 24.080 v13.0.0 (see <<_8, [8]>>) with the modifications specified in <<modifications-deviations-related-to-the-protocol-specification, Modifications/Deviations Related to the Protocol Specification>>. |

| == Modifications/Deviations Related to the Protocol Specification |
| |
| === Unimplemented and Implemented Messages, Information Elements and Constants |
| |
| ==== Messages for Mobility Management (MM) |
| |
| All the messages are implemented according to Table 9.2.1 and 10.2 of 24.008 (see <<_4, [4]>>). |
| |
| ==== Messages for Circuit Switched Call Control (CC) |
| |
| All the messages are implemented according to Table 9.54 and 9.3 of 24.008 (see <<_4, [4]>>). |
| |
| ==== GPRS Mobility Management (GMM) Messages |
| |
| All the messages are implemented according to Table 10.4 of 24.008 (see <<_4, [4]>>). |
| |
| ==== GPRS Session Management (SM) Messages |
| |
| All the messages are implemented according to Table 10.4a of 24.008 (see <<_4, [4]>>). |
| |
| ==== Common Information Elements (CommonIE) |
| |
| All the information elements implemented according to 10.5.1 of 24.008 (see <<_4, [4]>>). |
| |
| ==== Radio Resource Management (RRM) Messages |
| |
| Some of the messages that are used are implemented according to table 9.1.1 of 44.018 (see <<_5, [5]>>). |
| |
| ==== Short Message Service (SMS) Messages |
| |
| All the CP-messages are implemented according to 7.2 of 24.011 (see <<_6, [6]>>). |
| |
| All the RP-messages are implemented according to 7.3 of 24.011 (see <<_6, [6]>>). |
| |
| All the TPDU-messages are implemented according to 9.2.2 of 23.040 (see <<_7, [7]>>). |
| |
| ==== Supplementary Service Management (SS) Messages |
| |
| All the SS-messages are implemented according to table 2.1 of 24.080 (see <<_8, [8]>>). |
| |
| === Ericsson-Specific Changes |
| |
| None. |
| |
| == Backward Incompatibilities |
| |
| None. |
| |
| == System Requirements |
| |
| Protocol modules are a set of TTCN-3 source code files that can be used as part of TTCN-3 test suites only. Hence, protocol modules alone do not put specific requirements on the system used. However, in order to compile and execute a TTCN-3 test suite using the set of protocol modules the following system requirements must be satisfied: |
| |
| * Titan TTCN-3 Test Executor version CRL 113 200/5 R4A (5.4.pl0) or higher installed. For Installation Guide see <<_2, [2]>>. |
| |
| NOTE: This version of the test port is not compatible with Titan releases earlier than CRL 113 200/5 R4A. |
| |
| = Usage |
| |
| == Installation |
| |
| The set of protocol modules can be used in developing TTCN-3 test suites using any text editor; however, to make the work more efficient a TTCN3enabled text editor is recommended (for example `nedit`, `xemacs`). Since the MobileL3 protocol is used as a part of a TTCN-3 test suite, this requires TTCN-3 Test Executor be installed before the module can be compiled and executed together with other parts of the test suite. For more details on the installation of TTCN-3 Test Executor see the relevant section of <<_3, [3]>>. |
| |
| == Configuration |
| |
| None. |
| |
| == Examples |
| |
| None. |
| |
| = Interface Description |
| |
| == Top Level PDU |
| |
| The top level PDUs are the TTCN-3 records PDU_L3_MS_SGSN, PDU_L3_SGSN_MS, PDU_ML3_NW_MS, PDU_ML3_MS_NW. |

| [[encoding-decoding-and-other-related-functions]] |
| == Encoding/Decoding and Other Related Functions |
| |
| This product also contains encoding/decoding functions, which assure correct RAW encoding of messages when sent from TITAN and correct RAW decoding of messages when received by TITAN. |
