A method for data buffer memory management of an electronic device in a wireless network including storing, by processing circuitry, application data in an Application Processor (AP) buffer memory of the electronic device, determining, by the processing circuitry, a fraction of the application data from among the application data stored at the AP buffer memory based on at least one of a data rate capability of the electronic device, a data acknowledgment time or a tolerance time, and storing, by the processing circuitry, the fraction of the application data in a Communication Processor (CP) buffer memory of the electronic device for performing advanced Protocol Data Unit (PDU) formation (APF).

Methods, electronic devices and computer-readable media for data buffer memory management in wireless network

A method for handling a service connection in a wireless communication system, including detecting, by a User Equipment (UE), a Mobility Management (MM) service state of the UE is set to ATTEMPTING TO UPDATE, receiving, by the UE, a valid Temporary Mobile Subscriber Identity (TMSI) in a TMSI reallocation procedure from a base station via a Radio Resource Control (RRC) connection, changing, by the UE, the MM service state to a NORMAL SERVICE state in response to the receiving a valid TMSI and the detecting a MM service state, and sending, by the UE, a paging response message to the base station in response to the changing the MM service state and a paging indication message received from the base station to establish the service connection, the paging indication message including the valid TMSI.

Method and user equipment for handling service connectivity in wireless communication system

A method for handling checksum error in uplink data compression (UDC) in a wireless communication system includes: detecting, by user equipment (UE), a checksum failure; automatically controlling, by the UE, generation of a number of compressed protocol data units (PDUs) available for transmission at a Packet Data Convergence Protocol (PDCP) based on a package formation rate (PFT); and transmitting, by the UE, a number of compressed PDUs.

Method and system for handling checksum error in uplink data compression

A method for connecting to a Registered Public Land Mobile Network (RPLMN) after receiving an accept message with limited service from a user selected CSG cell, which is associated to a different PLMN than the RPLMN during manual CSG selection mode is disclosed. The method includes connecting to the RPLMN based on the availability of the user selected CSG cell in UTRAN. If the user selected CSG cell is not available in UTRAN, then the method includes connecting to the RPLMN by the UE using the stored duplicate value of the RPLMN. If the user selected CSG cell is available in UTRAN, then the method includes sending an ATTACH request to the user selected CSG cell without disabling the EUTRA capabilities. If the ATTACH request is failed, then the method includes connecting to the RPLMN using the stored duplicate value of the RPLMN.

Method for reducing battery power consumption of user equipment (UE) during manual CSG selection

A method performed by a user equipment (UE) for establishing a call in a wireless communication network, the method includes determining a first call control (CC) state of the UE after a recovery procedure for a call establishment is performed, sending a CC status enquiry message to a first base station connected to a first network, determining a second CC state of the first base station from a CC status message received from the first base station in response to the CC status enquiry message, and establishing the call by updating the first CC state based on the determined second CC state.

Methods and systems for handling call establishment by user equipment in wireless communication network

Embodiment herein achieves a method implemented in a mobile terminal. The method includes receiving a message from an entity in a network. Further, the method includes determining that a congestion timer T3246 is running, and performing one of stopping the timer T3246 and continuing the timer T3246. The method allows the UE to access the CS services when congestion at a MSC side is cleared.

Method for handling congestion timer upon receiving message from network

The various embodiments herein provide a method and system for optimizing Closed Subscriber Group (CSG) selection in wireless communication. The method comprising steps of initiating, by a user equipment (UE), a manual CSG selection, verifying if a manual CSG selection request is new, storing a registered public land mobile network (RPLMN) and a corresponding public land mobile network (PLMN) Selection mode if the CSG selection request is new, changing a PLMN selection mode and the CSG selection mode to MANUAL, registering the UE on to a user selected CSG cell, storing one or more parameters associated with the user selected CSG cell if the registration is successful irrespective of CSG cell belonging to RPLMN or different PLMN and selecting the user selected CSG cell using a stored PLMN ID and a CSG ID combination in the current PLMN selection mode during power off and power on.

Method and system for optimizing closed subscriber group (CSG) selection in wireless communication

A method for managing an extended Discontinuous Reception (eDRX) in a User Equipment (UE) including determining, by the UE, as to whether an eDRX enablement avoidance criterion is met, and causing, by the UE, to stop sending a request message, which is configured to enable the eDRX, to a network entity when the eDRX enablement avoidance criterion is met. The eDRX enablement avoidance criterion may include one of a data transmission pattern, a historic eDRX usage pattern, whether a configurable retry timer is deactivated, whether a number attempts made to enable the eDRX exceeds a threshold, whether a number of attempts made to enable and disable the eDRX exceeds a threshold, whether a request accept message including an indication that eDRX is not supported, is received from the network entity, or whether an indication of no eDRX support is received from the network entity may be provided.

Method and user equipment for managing extended discontinuous reception (eDRX)

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.

Method and system for user equipment behavior in manual CSG selection mode

A method of a terminal and the terminal are provided. The method includes detecting a location area change when a congestion timer is running and one of a general packet radio service (GPRS) update status indicating 'GU1 UPDATED,' a mobility management (MM) update status indicating 'U1 UPDATED,' and an evolved packet system &#x201c;EPS&#x201d; update status indicating &#x201c;EU1 UPDATED&#x201d; is indicated; adaptively changing the GPRS update status to &#x201c;GU2 NOT UPDATED,&#x201d; the MM update status to &#x201c;U2 NOT UPDATED,&#x201d; and the EPS update status to &#x201c;EU2 NOT UPDATED&#x201d;; and entering a state of &#x201c;GMM-REGISTERED.ATTEMPTING-TO-UPDATE,&#x201d; &#x201c;MM IDLE, ATTEMPTING TO UPDATE,&#x201d; or &#x201c;EMM-REGISTERED.ATTEMPTING-TO-UPDATE,&#x201d; in accordance with one of &#x201c;GU2 NOT UPDATED,&#x201d; &#x201c;U2 NOT UPDATED,&#x201d; and &#x201c;EU2 NOT UPDATED.&#x201d;

Method for managing a location of a terminal in wireless communication system

A method and system for minimizing delay in circuit-switched fallback (CSFB) procedure is disclosed. The disclosed method provides two different approaches for optimizing the delay during the CSFB procedure. In the first approach, user equipment (UE) receives a Location Area Identifier (LAI along with the Radio Access Technology (RAT) information from the network (LTE network). The UE uses the received RAT information from the network for switching to the target Radio Access Network (RAN) without informing to the LTE network. In another approach, the UE obtains the RAT information by performing a background scan in idle mode, when the UE receives LAI without RAT information from the network.
