3.8.25 Managing BS Reserved Parameters
3.8.26 Managing the BS Keep-Alive Functionality
Once an MS enters the network, its context is stored in ASN entities (BS,
ASN-GW). Dynamically, MS context could be transferred/updated (during HO and
re-authentication) to other entities or duplicated to other entities (separation
between anchor functions such as Authenticator, Data Path and Relay Data
Path).
In certain cases, such as entity reset, other entities are not aware of service
termination of an MS in that entity, and keep maintaining the MS context. This
may result in service failure, excessive consumption of memory resources and
accounting mistakes.
The keep-alive mechanism should be used to clear MS context from all network
entities when it is de-attached from the BS, and de-register MS from the network
when its context becomes unavailable in one of its serving function locations.
When the keep-alive mechanism is enabled the BS periodically polls other
ASN-GW entities-of-interest and waits for their responses. In case of no keep-alive
response, the BS shall make further actions, such as graceful de-registration of
applicable MS(s) and clearing the applicable MS(s) context.
NOTE
The BS reserved parameters table enables configuring up to 21 parameters that are reserved for
possible future use. In the current release none of the reserved parameters is being used.
Therefore, the following commands are not applicable:
