Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in enabling effective communication between terminal devices supporting dual connectivity technology and network devices, particularly in managing multiple connections and services simultaneously.
Innovation Solution
A communication method and apparatus that allow a terminal device to establish connections with multiple network devices, enabling the processing of multiple services by requesting the disabling or reconfiguration of existing connections, and establishing new connections with third network devices as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual SIM dual standby (DSDS) is implemented with one set of transceiver radio frequencies, then the mobile phone can maintain dual-SIM standby capability, but the two SIM cards cannot perform communication simultaneously causing call failure
Solution Approach 1:
The patent segments the communication resources by introducing multiple transceiver radio frequency sets (first set and second set) that operate independently. Each SIM card can be assigned to different frequency sets, allowing simultaneous communication without resource conflict, thus resolving the contradiction between dual-SIM standby capability and communication reliability
2Reliability
If dual SIM dual active (DSDA) technology is applied with two sets of transceiver radio frequencies, then simultaneous communication is enabled, but the complexity of managing multiple connections and services increases
Solution Approach 1:
The patent implements dynamic connection management where the terminal can flexibly establish, maintain, or release connections to different network devices based on service requirements. The system dynamically allocates transceiver radio frequency sets to different SIM cards and network devices, enabling simultaneous communication while adapting to changing service demands and reducing management complexity through automated resource allocation
3Productivity
If multiple connections are established to process multiple services, then service processing capability is improved, but resource utilization efficiency decreases due to connection management overhead
Solution Approach 1:
The patent changes the state parameters of connections dynamically based on service requirements. Connections can be established, suspended, or released according to whether services are active or inactive. This parameter-based management allows the system to maintain multiple service processing capabilities while optimizing resource utilization by releasing resources when not needed, thus improving energy efficiency

AI summary
The method includes: establishing, by a terminal device, a first connection to a first network device and a second connection to a second network device, where the first connection and the second connection are used to process a first service; and sending, by the terminal device, first information to the first network device if the terminal device determines that a second service needs to be processed, where the second service is different from the first service, where the first information is used to request to disable the first connection or the second connection, or the first information is used to indicate the terminal device to communicate with a third network device or establish a third connection to the third network device, where the third connection is used to process the second service.
