Abstract

In an example embodiment, a method of optimizing service delivery performed by a UE operating in EN-DC mode is disclosed. The method comprises detecting that a network service is ongoing at the UE using a first radio access technology (RAT), based on an application request sent by the UE to a network, wherein the first RAT is one of long-term evolution (LTE) and NR. The method further comprises detecting, during the ongoing network service being availed using the first RAT, a frequency of one or more NR network procedures being performed by the UE to be greater than a first threshold frequency. The method further comprises modifying a measurement interval associated with an NR cell measurement procedure, in response to detecting the frequency of the NR network procedures to be greater than the first threshold frequency. Furthermore, the method comprises continuing the Network Service using the first RAT.

First claim

The invention claimed is:

1. A method of user equipment (UE) for optimizing service delivery in a wireless communication system, the method comprising:
detecting, using a first radio access radio technology (RAT), a network service operating at the UE based on an application request transmitted to a network, wherein the first RAT is one of long-term evolution (LTE) or a new radio (NR);
detecting, during the network service operating at the UE, a frequency of one or more NR network procedures being performed by the UE, wherein the frequency is greater than a first threshold frequency;
modifying a measurement interval associated with an NR cell measurement procedure in response to detecting that the frequency of the one or more NR network procedures is greater than the first threshold frequency; and
maintaining the network service using the first RAT.

2. The method as claimed in claim 1 , further comprising increasing a current value of the measurement interval by a value of a pre-set time for each of the frequency of the one or more NR network procedures exceeding the first threshold frequency.

3. The method as claimed in claim 2 , further comprising:
sending, to the network, a message indicating a non-support of NR when a number of instances exceeds a threshold of a number of instances;
performing one of:
maintaining the network service using the first RAT when the first RAT is the LTE; or
terminating a connection with the NR and maintaining the network service over the LTE when the first RAT is the NR.

4. The method as claimed in claim 1 , further comprising:
determining a current location of the UE;
determining whether an identifier of the determined current location of the UE is present in a location database comprising one or more identifiers corresponding to, respectively, one or more locations where at least one of the UE and one or more other UEs haave experienced interference in the network service due to the frequency of the one or more NR network procedures, wherein the location database is stored in at least one of the UE and a network node;
storing the identifier associated with the determined current location of the UE in the location database based on a determination that the identifier of the determined current location of the UE is not present in the location database;
determining whether the current location of the UE is an interference location or not, based on at least one of:
the location database;
historic measurement data associated with the determined current location of the UE, wherein the historic measurement data comprises previously recorded frequency of NR procedures performed by at least one of the UE or one or more other UEs at the current location; and
a value of a plurality of network parameters at the current location of the UE, wherein the plurality of network parameters comprises a B1 threshold configured by the network, beam reference signal received power (RSRP), beam reference signal received quality (RSRQ), signal-to-interference-plus-noise ratio (SINR), a path loss value, a transmission power (Tx) of the UE, and a maximum transmit power level (MTPL) of the UE;

sending, to the network, a message indicating a non-support of the NR based on a determination that the current location of the UE is the interference location; and
performing one of:
maintaining the network service using the first RAT when the first RAT is the LTE; or
terminating a connection with the NR and maintaining the network service over the LTE when the first RAT is the NR.

5. The method as claimed in claim 4 , further comprising:
detecting a change in the current location of the UE;
determining the changed location of the UE as a non-interference location based on at least one of the location database, the historic measurement data, and the value of the plurality of network parameters; and
sending a request to the network to connect to the NR in response to determining that the changed location of the UE is the non-interference location.

6. The method as claimed in claim 4 , further comprising:
monitoring a status of the network service;
detecting a completion of the network service based on the monitored status of the network service; and
sending a request to the network to connect to the NR in response to detecting the completion of the network service.
