`ABSTRACT
`(57)
`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 authen-
`tication 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 secondset 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

`node, and receiving only the first set of subscription
`data on the basis of a partial transfer indication asso-
`ciated with the user equipment
`in the subscription
`database; and
`transmitting a request from the attach control node to the
`subscriber database, the request containing a partial
`transfer indication[; and
`receiving subscriber data from the subscriber database
`and storing only a first set of subscriber data from the
`received subscriber data in response to a partial attach
`state indication in the attach control node].
`6. The method according to claim 1, further comprising
`deleting from the combinationofthefirst set of subscription
`data and the secondset of subscription data the [at least one]
`second set of subscription data at the attach contro] node
`after a precondition has been fulfilled [and, if the telecom-
`munications system is an LTE telecommunications system,
`removing a default bearer for the user equipment].
`7. The method according to claim 1, wherein the tele-
`communications system comprises [an LTE] a Long Term
`Evolution (LTE) telecommunications system, and wherein
`the method further [comprising] comprises:
`omitting establishing a default bearer on a radio path
`between the user equipment and the LTE telecommu-
`nications system prior to initiation of the secondtrans-
`fer stage;
`providing the user equipment with information indicative
`of non-establishment of the default bearer prior to the
`initiation of the second transfer stage; and
`establishing the default bearer upon orafter initiation of
`the second transfer stage by the attach control node.
`8. A non-transitory computer-readable medium having
`instructions stored thereon that, upon execution by one or
`more processors of an attach control node of a telecommu-
`nications system comprising [an] ¢he attach control node and
`a subscriber database containing subscription data of a user
`equipment, cause the [one or more processors] the attach
`control node 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, as received, the first set of subscription data,
`being configured as a partial subset of a complete set
`of subscription data that are required for enabling
`establishing a communication session betweenthe user
`equipmentandthe telecommunications sysiem, 1s insuf-
`ficient for enabling establishing a communication ses-
`sion between the user equipment and the telecommu-
`nications 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];
`required
`if establishing a communication session is
`between the user equipment and the telecommunica-
`tions [network] system, subsequentto receiving thefirst
`set of subscription data, receiving in a secondtransfer
`stage following the first transfer stage [at least one] 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 [a combination of] as received,
