Method and Telecommunications Node for Controlling an Attach State of a User Equipment
First Claim
1. A method for controlling an attach state of a user equipment in an attach control node of a telecommunications system further comprising a subscriber database containing subscription data of the user equipment, the method comprising:
- receiving in a first transfer stage a first set of subscription data from the subscriber database and storing the first set of subscription data in the attach control node, wherein the first set of subscription data is insufficient for enabling establishing a communication session between the user equipment and the telecommunications system, and wherein, if an authentication step is required, authentication data are received in the attach control node prior to the receiving in the first transfer stage;
if establishing a communication session is required between the user equipment and the telecommunications network, receiving in a second transfer stage following the first transfer stage at least one second set of subscription data from the subscriber database in the attach control node, and storing the second set of subscription data in the attach control node, wherein a combination of the first set of subscription data and the second set of subscription data is sufficient for enabling establishing a communication session between the user equipment and the telecommunications network.

Abstract
The invention relates to a method and telecommunications node for controlling an attach state of a user equipment in an attach control node of a telecommunications system further comprising a subscriber database containing subscription data of the user equipment. The method comprises receiving authentication data in the attach control node if an authentication step is required. Following the authentication step, if any, receiving in a first transfer stage a first set of subscription data from the subscriber database and storing the first set of subscription data in the attach control node, wherein the first set of subscription data is insufficient for enabling establishing a communication session between the user equipment and the telecommunications system. If establishing a communication session is required between the user equipment and the telecommunications network, receiving in a second transfer stage following the first transfer stage a second set of subscription data from the subscriber database in the attach control node, and storing the second set of subscription data in the attach control node, wherein the combination of the first set of subscription data and the second set of subscription data is sufficient for enabling establishing a communication session between the user equipment and the telecommunications network.

8. A non-transitory computer-readable medium having instructions stored thereon that, upon execution by one or more processors of a telecommunications system comprising an attach control node and a subscriber database containing subscription data of a user equipment, cause the one or more processors to carry out operations including:
-
receiving in a first transfer stage a first set of subscription data from the subscriber database and storing the first set of subscription data in the attach control node, wherein the first set of subscription data is insufficient for enabling establishing a communication session between the user equipment and the telecommunications system, and wherein, if an authentication step is required, authentication data are received in the attach control node prior to the receiving in the first transfer stage; if establishing a communication session is required between the user equipment and the telecommunications network, receiving in a second transfer stage following the first transfer stage at least one second set of subscription data from the subscriber database in the attach control node, and storing the second set of subscription data in the attach control node, wherein a combination of the first set of subscription data and the second set of subscription data is sufficient for enabling establishing a communication session between the user equipment and the telecommunications network.

9. A subscriber database system configured for use in a telecommunications system, wherein the telecommunications system comprises an attach control node, the subscriber database system comprising:
-
a subscriber database containing subscription data of a user equipment; a processor having access to instructions that when executed cause the database system to carry out operations including; in a first transfer stage, providing to the attach control node a first set of subscription data from the subscriber database, wherein the first set of subscription data is insufficient for enabling establishing a communication session between the user equipment and the telecommunications system, and wherein, if the attach control received authentication data in an authentication step, the first transfer stage is carried out following the authentication step, if establishing a communication session is required between the user equipment and the telecommunications network, then in a second transfer stage following the first transfer stage, providing to the attach control node at least one second set of subscription data from the subscriber database, wherein a combination of the first set of subscription data and the second set of subscription data is sufficient for enabling establishing a communication session between the user equipment and the telecommunications network.
