## Abstract

When mobile terminated devices sleep, the devices might not be reachable when needed, for instance when the device is a recipient of data from a third party server. As described herein, a third party application server may inform the network that it has data to send to a particular UE or group of UEs. In an example, the mobile core network (MCN) may use information from the third party server to ensure that the UE is awake when it needs to be. For example, a given UE or group of UEs can be prevented from entering a sleep state before a data transfer is completed.

## Claims

### Claim 1

An apparatus comprising a processor, a memory, and communication circuitry, the apparatus being connected to a network via its communication circuitry, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to perform operations comprising:
receiving a first data delivery request message that indicates at least one user equipment (UE) that will be a recipient of data during a data transfer from a third party server, the first data delivery request message further indicating when the third party server would like to perform the data transfer; and
based on the first data delivery request message, performing an action to ensure that the at least one UE is awake for the data transfer.

### Claim 2 (depends on 1)

The apparatus as recited in claim 1, the apparatus further comprising computer-executable instructions which, when executed by the processor of the apparatus, cause the apparatus to perform further operations comprising:
receiving a transfer policy associated with the at least one user equipment, such that the action is also based on the transfer policy,
wherein the transfer policy indicates whether one or more sleep modes are used by the at least one UE.

### Claim 3 (depends on 1)

The apparatus as recited in claim 1, wherein the at least one user equipment is a group of user equipments, such that the action ensures that each UE in the group is awake for the data transfer at the same time as each other.

### Claim 4 (depends on 1)

The apparatus as recited in claim 1, wherein performing the action comprises paging the at least one UE upon receiving the first data delivery request message.

### Claim 5 (depends on 4)

The apparatus as recited in claim 4, the apparatus further comprising computer-executable instructions which, when executed by the processor of the apparatus, cause the apparatus to perform further operations comprising:
after paging the at least one UE so that the UE is in a radio resource control (RRC) connected state, refraining from releasing the at least one UE from the RRC connected state until at least one of a time window in the first data delivery request message has passed, the data transfer is complete, or a timer expires.

### Claim 6 (depends on 1)

The apparatus as recited in claim 1, wherein performing the action comprises preventing the at least one UE from entering a power savings mode (PSM) or extended idle mode discontinuous reception (eDRX) until a time window in the first data delivery request message has passed.

### Claim 7 (depends on 6)

The apparatus as recited in claim 6, wherein preventing the at least one UE from entering the PSM or eDRX comprises rejecting a timer value that is proposed by the at least one UE during a tracking area update.

### Claim 8 (depends on 6)

The apparatus as recited in claim 6, wherein preventing the at least one UE from entering the PSM or eDRX comprises adjusting a timer associated with the at least one UE and a tracking area update timer associated with the at least one UE such that the at least one UE is awake when the data transfer is performed.

### Claim 9 (depends on 1)

The apparatus as recited in claim 1, wherein performing the action comprises sending a second data delivery request message to a radio access node in the network, wherein the data delivery request message comprises a request to page the at least one UE.

### Claim 10

A method performed by an apparatus connected to a network, the method comprising:
receiving a first data delivery request message that indicates at least one user equipment (UE) that will be a recipient of data during a data transfer from a third party server, the first data delivery request message further indicating when the third party server would like to perform the data transfer; and
based on the first data delivery request message, performing an action to ensure that the at least one UE is awake for the data transfer.

### Claim 11 (depends on 10)

The method as recited in claim 10, the method further comprising:
receiving a transfer policy associated with the at least one user equipment, such that the action is also based on the transfer policy,
wherein the transfer policy indicates whether one or more sleep modes are used by the at least one UE.

### Claim 12 (depends on 10)

The method as recited in claim 10, wherein the at least one user equipment is a group of user equipments, such that the action ensures that each UE in the group is awake for the data transfer at the same time as each other.

### Claim 13 (depends on 1)

The method as recited in claim 1, wherein performing the action comprises paging the at least one UE upon receiving the first data delivery request message.

### Claim 14 (depends on 13)

The method as recited in claim 13, the method further comprising:
after paging the at least one UE so that the UE is in a radio resource control (RRC) connected state, refraining from releasing the at least one UE from the RRC connected state until at least one of a time window in the first data delivery request message has passed, the data transfer is complete, or a timer expires.

### Claim 15 (depends on 10)

The method as recited in claim 10, wherein performing the action comprises preventing the at least one UE from entering a power savings mode (PSM) or extended idle mode discontinuous reception (eDRX) until a time window in the first data delivery request message has passed.

### Claim 16 (depends on 15)

The method as recited in claim 15, wherein preventing the at least one UE from entering the PSM or eDRX comprises rejecting a timer value that is proposed by the at least one UE during a tracking area update.

### Claim 17 (depends on 15)

The method as recited in claim 15, wherein preventing the at least one UE from entering the PSM or eDRX comprises adjusting a timer associated with the at least one UE and a tracking area update timer associated with the at least one UE such that the at least one UE is awake when the data transfer is performed.

### Claim 18 (depends on 1)

The method as recited in claim 1, wherein performing the action comprises sending a second data delivery request message to a radio access node in the network, wherein the data delivery request message comprises a request to page the at least one UE.
