A method for preventing a task-signal deadlock arising due to contention for a mutex in a real-time operating system (RTOS) includes detecting, by a processing unit, a signal notification sent to a task for execution of a signal handler; identifying, by the processing unit, a mutex to be acquired by the signal handler, when the signal notification is detected; determining whether the identified mutex has been acquired by the task; and utilizing, by the processing unit, an alternative stack for execution of the signal handler, in response to determining that the mutex has been acquired by the task, for preventing a task-signal deadlock during the execution.

A method of generating a core dump in a User Equipment (UE) may include detecting, using at least one processor, a trigger, the trigger including an instruction to generate a core dump of the UE. The method may further include classifying, using the at least one processor, data stored in memory of the UE as Read-Write (RW) data or Read Only (RO) data. The method may further include generating, using the at least one processor, a partial core dump based on the RW data of the memory.

Methods and systems for generating core dump in a user equipment

A method for managing memory leaks in a memory device includes grouping, by a garbage collection system, a plurality of similar memory allocations of the memory device into one or more Unique Fixed Identifiers (UFIs); identifying, by the garbage collection system, one of the one or more UFIs having a highest accumulated memory size and adding each of the plurality of memory allocations in the identified one of the one or more UFIs into a Potential Leak Candidate List (PLCL); identifying, by the garbage collection system, the memory leaks in the memory device by identifying unreferenced memory addresses associated with the plurality of memory allocations in the PLCL; and releasing, by the garbage collection system, the identified unreferenced memory addresses associated with the plurality of memory allocations corresponding to the memory leaks into the memory device.

An apparatus is configured to collect information related to a first activity and analyze the collected information to determine decision data. The information is stored in a first list of the source processing core for scheduling execution of the activity by a destination processing core to avoid cache misses. The source processing core is configured to transmit information related to the decision data using an interrupt, to a second list associated with a scheduler of the destination processing core, if the destination processing core is currently executing a second activity having a lower priority than the first activity.

Systems and methods are described for simultaneously accessing a plurality of services on Wi-Fi. The method comprises registering a first and second Media Access Control (MAC) identification (ID) with a first and second IP Multimedia System (IMS), by use of a User Equipment (UE). The UE comprises a first MAC ID associated with a first Subscriber Identification Module (SIM) card and a second MAC ID associated with a second SIM card. Use of a first service through a first Access Point (AP) without interrupting a second service may be available with registration of a first and second MAC ID.

Method and a user equipment (UE) for accessing plurality of services on Wi-Fi simultaneously

A method performed by a User Equipment (UE) for managing sub-flow communications is provided, the method includes selecting a sub-flow among a plurality of sub-flows of the UE based on a set of parameters associated with each of the plurality of sub-flows, and transmitting a plurality of Transmission Control Protocol (TCP) acknowledgement messages in a single frame through the selected sub-flow, the plurality of TCP acknowledgement messages being associated with the plurality of sub-flows.
