Abstract: A method for handling an ATTACH reject message with packet radio service mobility management reject cause number (#14 cause) at a user equipment (UE) is provided. The method includes receiving, at the UE, an ATTACH accept message for a network service on a public land mobile network (PLMN) from a first network entity, wherein the PLMN is in a “forbidden PLMNs for general packet radio service (GPRS) service” list, detecting, by the UE, that the UE's evolved universal terrestrial radio access (E-UTRA) capability is disabled, and enabling, by the UE, the UE's E-UTRA capability and removing the PLMN from the “forbidden PLMNs for GPRS service” list.

Abstract: A method and system for enabling a User Equipment (UE) to quickly recover back to normal service on failure of registration attempt to a selected Closed Subscriber Group (CSG) cell or loss of coverage of the selected CSG cell is provided. The method provides a UE behavior during manual CSG selection mode when the selected CSG cell is associated with a different Public Land Mobile Network (PLMN) than the Registered PLMN (RPLMN) of the UE. The method also defines the UE actions to handle a user request to change a current Public Land Mobile Network (PLMN) selection mode and handle expiry of a Home PLMN (HPLMN) timer in the UE, when the UE is attached to the selected CSG cell in the manual CSG selection mode.

Abstract: A method for retaining a Robust Header Compression (ROHC) state in a User Equipment (UE) during switching from a Voice over Long Term Evolution (VoLTE) call to a video call or vice versa is provided. When the VoLTE call is in progress and if a user switches the VoLTE call to the video call, then the RTP header information is sent to an Application Processor (AP) from a Communication Processor (CP). The ROHC compressor continues the compression of the RTP packets using the existing built context for the video call. Further, when the video call is in progress and if the user switches the video call to the VoLTE call, then the RTP header information is sent to the CP from the AP. The ROHC context is reused by exchanging the RTP header information between the AP and the CP.

Abstract translation: 提供了一种用于在从长时间演进语音（VoLTE）呼叫切换到视频呼叫或反之亦然的过程中，在用户设备（UE）中保持鲁棒头部压缩（ROHC）状态的方法。 当VoLTE呼叫进行中，如果用户将VoLTE呼叫切换到视频呼叫，则RTP头信息从通信处理器（CP）发送到应用处理器（AP）。 ROHC压缩器使用用于视频呼叫的现有内置上下文继续RTP分组的压缩。 此外，当视频呼叫正在进行时，如果用户将视频呼叫切换到VoLTE呼叫，则RTP头信息从AP发送到CP。 通过在AP和CP之间交换RTP头信息来重用ROHC上下文。

Abstract: A method and system to use existing Non-access stratum (NAS) signaling connection for pending uplink signaling/data after Tracking Area Update Procedure (TAU) complete is disclosed. The proposed method handles the EPS Session Management (ESM), Short Message Service (SMS) or voice call or data when a User Equipment (UE) is waiting for TAU accept. The method allows UE to inform the network with specific Information Element (IE) in TAU complete message, so that the network will take the next action. This will help to provide quick services to the user. Using the “CONN REQ TYPE” IE, in TAU complete, to handle all abnormal Cases for Circuit Switches (CS) services/data services in E-UTRAN (Evolved UTRAN) network.

Abstract: The present disclosure provides a method for improving call performance in a wireless network. The method includes sending an invite request to a server to initiate a Voice over New Radio (VoNR) service, where the UE is connected with a first network entity, and where the invite request comprises a media feature tag. The method includes initiating an Evolved Packet System fallback (EPS FB) service timer based on the media feature tag and a quality of service (QoS) timer and establishing a call over a second network entity using a dedicated bearer when the EPS FB command is received from the server. The call is established over the second network entity using the dedicated bearer by sending a service request to the server and/or sending an update request to the server when the EPS FB timer is expired and the EPS FB command is not received from the server.
