• inhibiting, in response to receiving the first value, the one or more old user equipment capability identifiers;
• and
• sending the first value and the first user equipment capability identifier to the user equipment or a radio access network.

A user equipment comprising:

• at least one processor;
• at least one memory including program code;
• and
• a transceiver in operable communication with the at least one processor,
• wherein the at least one memory and the program code are configured to, with the at least one processor, cause the user equipment to at least:
• receive, via the transceiver, at least one first message comprising at least one first user equipment capability identifier associated with one or more user equipment capabilities, wherein the at least one first message further comprises at least one first value;
• receive, via the transceiver, at least one second message comprising at least one second user equipment capability identifier associated with the one or more user equipment capabilities, wherein the at least one second message further comprises at least one second value;
• make a determination, based at least upon a comparison of the at least one first value and the at least one second value, that the at least one first user equipment capability identifier associated with the at least one first value is stale or no longer valid;
• and
• store, in a cache at the user equipment, based on the determination, the at least one second value and the at least one second user equipment capability identifier.

A user equipment comprising:

• at least one processor;
• at least one memory including program code;
• and
• a transceiver in operable communication with the at least one processor,
• wherein the at least one memory and the program code are configured to, with the at least one processor, cause the user equipment to at least:
• receive, via the transceiver, a registration accept message or a configuration update message, wherein the registration accept message indicates that a registration request previously provided by the user equipment to a network element of a communication system has been accepted by the communication system, wherein the configuration update message comprises an indication of configuration information for communication between the user equipment and the network element of the communication system, wherein the registration accept message or the configuration update message comprises a first user equipment capability identifier associated with at least one user equipment capability, and wherein the registration accept message or the configuration update message further comprises at least one first value;
• store, in a cache of the user equipment, the first user equipment capability identifier associated with at least one user equipment capability and the at least one first value;
• receive, via the transceiver, another configuration update message, the another configuration update message comprising at least one second user equipment capability identifier associated with the one or more user equipment capabilities, wherein the another configuration update message further comprises at least one second value;
• make a determination, based on a comparison of the at least one first value with the at least one second value, that the at least one first user equipment capability identifier is stale or no longer valid;
• and
• based on the determination that the at least one first user equipment capability identifier is stale or no longer valid, determine that the at least one first user equipment capability identifier should not be used.

A method comprising:

• receiving, at a user equipment, from a network element of a communication system, at least one first message comprising at least one first user equipment capability identifier associated with one or more user equipment capabilities, wherein the at least one first message further comprises at least one first value;
• receiving, at the user equipment, from the network element of the communication system, at least one second message comprising at least one second user equipment capability identifier associated with the one or more user equipment capabilities, wherein the at least one second message further comprises at least one second value;
• making a determination, based on a comparison of the at least one first value with the at least one second value, that the at least one first user equipment capability identifier is stale or no longer valid;
• and
• based on the determination that the at least one first user equipment capability identifier is stale or no longer valid, prioritizing removal of the at least one first user equipment capability identifier from a cache of the user equipment and storing, in the cache, the at least one second value and the at least one second user equipment capability identifier.

A method comprising:

• receiving, at a user equipment, a registration accept message or a configuration update message, the registration accept message or the configuration update message comprising a first user equipment capability identifier associated with at least one user equipment capability, wherein the registration accept message or the configuration update message further comprises at least one first value;
• storing, in a cache of the user equipment, the first user equipment capability identifier associated with the at least one user equipment capability and the at least one first value;
• receiving, at the user equipment, another configuration update message, the another configuration update message comprising at least one second user equipment capability identifier associated with the one or more user equipment capabilities, wherein the at least one second message further comprises at least one second value;
• making a determination, based on a comparison of the at least one first value with the at least one second value, that the at least one first user equipment capability identifier is stale or no longer valid;
• and
• based on the determination that the at least one first user equipment capability identifier is stale or no longer valid, determining that the at least one first user equipment capability identifier should not be used.

A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to perform at least:

• receiving, at a user equipment, at least one first message comprising at least one first user equipment capability identifier associated with one or more user equipment capabilities, wherein the at least one first message further comprises at least one first value;
• receiving, at the user equipment, at least one second message comprising at least one second user equipment capability identifier associated with the one or more user equipment capabilities, wherein the at least one second message further comprises at least one second value;
• making a determination, based on a comparison of the at least one first value with the at least one second value, that the at least one first user equipment capability identifier is stale or no longer valid;
• based on the determination that the at least one first user equipment capability identifier is stale or no longer valid, storing, in a cache at the user equipment, the at least one second value and the at least one second user equipment capability identifier;
• and
• based on the determination that the at least one first user equipment capability identifier is stale or no longer valid, prioritizing removal of the at least one first user equipment capability identifier from the cache.

A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to perform at least:
