START-5 Message codes of consecutive alerts with the same message identifier and that overlap in area and time
Description
This TC is only applicable if the CBC supports sending multiple alerts of the same level being broadcasted at the same time.
Since the two alerts have the same level (e.g. they are both EU-Alert level 2) and are in the same language, they will have the same message identifier. Also, the GS and Update Number fields of the Serial Number will be the same, since the second alert is NOT updating the first one but it is a completely new one. The only way for the two alerts to have different message references in the overlapping area is for the CBC to use different values of their Message Code field inside the Serial Number.
Verify that message codes inside the serial number change from one independent alert to the next one that has the same message identifier.
Pre-requisites
- There is no ongoing cell broadcast in any of the cells that cover the alert area.
- The messages for the two alerts are either both in the local language or both in the same or different non-local language (different iterations of this TC).
- Alert timing defined for the two alerts are defined so they overlap.
- Same alert area for both alerts.
Steps to execute
- CBE sends CAP Alert message with:
- A single info element. I.e. only one message in one language.
- alertinfo.language.code set to the value of the language applicable to the current iteration of this test case (e.g. sl-SI for Slovenian).
- alertinfo.instruction.text content of the alert message in the language of the code above. The message of this message should be such that it needs four pages when encoded.
- Time information that allows the CBC to calculate the repetition period and the number of repetitions in a way that overlaps with the next alert.
- Alert area that is inside the area controlled by a single MME. I.e. only one MME is involved in this test.
- Wait for the alert in step one to become active.
- CBE sends CAP Alert message with:
- A single info element. I.e. only one message in one language.
- alertinfo.language.code set to the value of the language applicable to the current iteration of this test case .
- alertinfo.instruction.text content of the alert message in the language of the code above.
- Time information that allows the CBC to calculate the repetition period and the number of repetitions in a way that overlaps with the previous alert.
- Same alert area as in step 1.
Information flow
Result
Verify that:
- The values of the message code field inside the Serial Number IE of the WRITE-REPLACE-WARNING-REQUEST in flows 2 and 5 are different.
- Both alerts are broadcasted simultaneously while they are both active.
- Handsets in the alert area receive and display the alerts correctly.
Iterations
This TC should be iterated for the alert types and language combinations in the following table that are applicable in the country in which the CBC is deployed:

TIP
Note that there are iterations for the same and for different additional languages.
If, for example, English and German are non-local languages used in alerts in your region, then for iterations with the same additional, send the two alerts in English or the two alerts in German, and for iterations with different additionals, send one alert in English and one in German.
