Abstract
Techniques for preventing denial of call transfer are provided. For example, a method, comprises: indicating, in an apparatus, that a call pull is initiated; categorizing, in the apparatus, an access attempt occurred for the call pull as a mobile-terminated access attempt; and making, in the apparatus, the access attempt to a network by transmitting a message to enable a process for the call pull, wherein the message includes a cause value set according to the categorization of the access attempt. The method may be performed by a user equipment (UE).
Claims21
A method for a first user equipment (UE), the method comprising:
- indicating, by the first UE, that a call pull is initiated based on determining that the call pull is initiated to pull, to the first UE, a call from a second user equipment (UE);
- categorizing, by the first UE, an access attempt occurred for the call pull as a mobile-terminated access attempt;
- causing, by the first UE, the access attempt to be considered not barred in response to the access attempt being categorized as the mobile-terminated access attempt;
- and
- performing, by the first UE, the access attempt to a network by transmitting a message to enable a process for the call pull,
- wherein the message includes a cause value set according to the categorization of the access attempt, and wherein the cause value is set a value representing the mobile-terminated access attempt.
A method for an apparatus, the method comprising:
- receiving, from a user equipment, a message to enable a process for a call pull based on determining that the call pull is initiated to pull, from the apparatus, a call to the user equipment including a cause value set according to categorization of an access attempt;
- and
- performing an access control based on the cause value,
- wherein:
- the access attempt is for a call pull;
- and
- the access attempt is categorized as a mobile-terminated access attempt.
A first user equipment (UE), the first UE comprising:
- at least one processor;
- and
- at least one memory storing computer program code that, when executed with the at least one processor, causes the first UE at least to:
- indicate that a call pull is initiated based on determining that the call pull is initiated to pull, to the first UE, a call from a second user equipment (UE);
- categorize an access attempt occurred for the call pull as a mobile-terminated access attempt;
- cause the access attempt to be considered not barred in response to the access attempt being categorized as the mobile-terminated access attempt;
- and
- perform the access attempt to a network by transmitting a message to enable a process for the call pull,
- wherein the message includes a cause value set according to the categorization of the access attempt, and wherein the cause value is set to a value representing the mobile-terminated access attempt.
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing computer program code that, when executed with the at least one processor, causes the apparatus at least to:
- receive, from a user equipment, a message to enable a process for a call pull based on determining that the call pull is initiated to pull, from the apparatus, a call to the user equipment including a cause value set according to categorization of an access attempt;
- and
- perform an access control based on the cause value,
- wherein:
- the access attempt is for a call pull;
- and
- the access attempt is categorized as a mobile-terminated access attempt.
