Abstract
Embodiments of the present disclosure provide a method and an entity for checking port consistency of NIDD message. A first aspect of the present disclosure provides a method performed at a first entity (100), comprising: receiving (S101), from a second entity, a non-internet protocol data delivery, NIDD, message including one or more RDS port numbers; and determining (S102) whether the one or more RDS port numbers are within a configured RDS port list. According to embodiments of the present disclosure, network resources for transmitting the invalid NIDD data may be saved, and undesired actions in the communication system may be avoided.
Claims23
A method performed at a first entity, comprising:
- receiving, from a second entity, a non-internet protocol data delivery (NIDD) message comprising a first Reliable Data Service (RDS) port number;
- and
- after receiving the NIDD message comprising the first RDS port number, determining whether the first RDS port number included in the NIDD message is within a configured RDS port list;
- and
- as a result of determining that the first RDS port number is not within the configured RDS port list, transmitting to the second entity a response message indicating that at least one RDS port number included in the NIDD message is unknown in the first entity.
A method performed at a second entity, comprising:
- transmitting, to a first entity, a non-internet protocol data delivery (NIDD) message comprising a first Reliable Data Service (RDS) port number;
- and
- after transmitting the NIDD message to the first entity, receiving from the first entity a response message indicating that an RDS port number included in the NIDD message is not included in a configured RDS port list.
An apparatus, comprising:
- a receiver for receiving messages;
- a processor;
- and
- a memory, containing instructions executable by the processor, wherein the apparatus is configured to perform a method comprising:
- after receiving a non-internet protocol data delivery (NIDD) message comprising a first Reliable Data Service (RDS) port number, determining whether the first RDS port number included in the NIDD message is within a configured RDS port list;
- and
- as a result of determining that the first RDS port number is not within the configured RDS port list, transmitting a response message, responsive to the NIDD message, indicating that at least one RDS port number included in the NIDD message is unknown in the first entity.
An apparatus, comprising:
- a processor;
- and
- a memory, containing instructions executable by the processor, wherein the apparatus is configured to perform a method comprising:
- transmitting, to a first entity, a non-internet protocol data delivery (NIDD) message comprising a first Reliable Data Service (RDS) port number;
- and
- after transmitting the NIDD message to the first entity, receiving from the first entity a response message indicating that an RDS port number included in the NIDD message is not included in a configured RDS port list.
