## Abstract

The disclosed subject matter provides techniques for managing negotiation of power saving mode (PSM) parameters between a user equipment (UE) and core network device of a wireless communication network. In this regard, a method is provided that includes facilitating establishing, by a device comprising a processor, a wireless communication link with a network device of a wireless network. The method can further include, based on a determination that a power saving mode retry protocol for the device is enabled, determining, by the device, a number of times the network device previously instructed the device to use network values for power saving mode timers instead of device values for the power saving mode timers in association with the device operating in a power saving mode.

## Claims

### Claim 1

A method, comprising:
controlling, by a network device of a communication network, a retry control functionality of a device that receives a network service via the communication network, wherein the controlling comprises limiting a number of times the device is able to request usage of a device value for a parameter of a power saving mode after having been previously instructed by the network device to use a network value for the parameter, wherein the network device is operatively coupled to a processor,
wherein the controlling further comprises:
determining, by the network device, a retry threshold value based on a current network condition of the communication network;
setting, by the network device, the retry threshold value on a subscriber identity module card of the device, wherein the retry threshold value limits the number of times the device is able to request the usage of the device value for the parameter of the power saving mode after having been previously instructed by the network device to use the network value for the parameter; and
sending, by the network device, a control message directing the device to enable the retry control functionality by applying the retry threshold value.

### Claim 2 (depends on 1)

The method of claim 1, wherein the parameter comprises a duration of an idle mode of the power saving mode.

### Claim 3 (depends on 1)

The method of claim 1, wherein the parameter comprises a duration of a low power mode of the power saving mode.

### Claim 4 (depends on 1)

The method of claim 1, wherein the parameter comprises an active timer for the power saving mode.

### Claim 5 (depends on 1)

The method of claim 1, wherein the sending comprises sending the control message as an over the air message.

### Claim 6 (depends on 1)

The method of claim 1, wherein the current network condition comprises a current load of the network device.

### Claim 7 (depends on 1)

The method of claim 1, wherein the current network condition comprises a current signal scheduling constraint of the network device.

### Claim 8

A system, comprising:
a processor of a network device; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
determining to control a retry control functionality of a device in association with operation of the device using a communication network; and
based on the determining, controlling the retry control functionality of the device in association with operation of the device using the communication network, wherein the controlling comprises limiting a number of times the device is able to request usage of a device value for a parameter of a power saving mode after having been previously instructed by the network device of the communication network to use a network value for the parameter,
wherein the controlling further comprises:
determining a retry threshold value based on a current network condition of the communication network;
setting the retry threshold value on a subscriber identity module card of the device, wherein the retry threshold value limits the number of times the device is able to request the usage of the device value for the parameter of the power saving mode after having been previously instructed by the network device to use the network value for the parameter; and
sending a control message directing the device to enable the retry control functionality by applying the retry threshold value.

### Claim 9 (depends on 8)

The system of claim 8, wherein the parameter comprises a duration of an idle mode of the power saving mode.

### Claim 10 (depends on 8)

The system of claim 8, wherein the parameter comprises a duration of a low power mode of the power saving mode.

### Claim 11 (depends on 8)

The system of claim 8, wherein the parameter comprises an active timer for the power saving mode.

### Claim 12 (depends on 8)

The system of claim 8, wherein the current network condition comprises a current load of the network device.

### Claim 13 (depends on 8)

The system of claim 8, wherein the current network condition comprises a current signal scheduling constraint of the network device.

### Claim 14 (depends on 8)

The system of claim 8, wherein the sending comprises sending the control message as an over the air message.

### Claim 15

A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor of a network device, facilitate performance of operations, the operations comprising:
controlling a retry control functionality of a device in association with operation of the device using a communication network, wherein the controlling comprises limiting a number of times the device is capable of requesting usage of a device value for a parameter of the power saving mode after having been previously instructed, by the network device of the communication network, to use a network value for the parameter,
wherein the controlling further comprises:
determining a retry threshold value based on a current network condition of the communication network;
setting the retry threshold value on a subscriber identity module card of the device, wherein the retry threshold value limits the number of times the device is able to request the usage of the device value for the parameter of the power saving mode after having been previously instructed by the network device to use the network value for the parameter; and
sending a control message directing the device to enable the retry control functionality by applying the retry threshold value.

### Claim 16 (depends on 15)

The non-transitory computer machine-readable storage medium of claim 15, wherein the parameter comprises a duration of an idle mode of the power saving mode.

### Claim 17 (depends on 15)
