  • Patent number: 11622327
    Abstract: According to implementations of the subject matter described herein, a new approach for receiving the CBS message is proposed. Generally speaking, upon receipt of CBS messages from a network device in a first receiving time interval of a first DRX period, a terminal device will detect whether there is a change among the CBS messages. On the basis of the detection, the terminal device will determine a configuration of a second DRX period that at least includes a second dormant time interval after the first receiving time interval and a second receiving time interval for receiving further CBS messages. That is, the further CBS messages are received in a second DRX period determined through a self-learning process performed on the received CBS messages and the first DRX period. In this way, the power consumption of the terminal device for receiving the CBS messages can be reduced. As a result, the battery life of the terminal device can be guaranteed.

  • Patent number: 11611920
    Abstract: A system for delaying or inhibiting data is provided in order to shorten the time required for a reselection process from a first communication protocol to a second communication protocol. Reselection from the first communication protocol to the second communication protocol (e.g., 3G to 4G) requires a period of time without data transfers to allow the reselection to complete. The system delays or inhibits data transfers on the mobile device until the reselection process completes or the mobile device is idle for a predetermined length of time. In an embodiment, the system can buffer outgoing data and then send the data once the reselection has completed. In other embodiments, the system can drop packet sessions or ignore incoming packet pages. In another embodiment, the system can delay or inhibit data based on the priority of the data.

  • Patent number: 11558789
    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention provides a method for controlling Wireless Local Area Network (WLAN) aggregation and an associated equipment. The method comprises the following steps of: acquiring, by a first radio access network node, WLAN information about a User Equipment (UE); and, controlling, by the first radio access network node, WLAN aggregation for the UE according to the acquired WLAN information. A second radio access network node decides whether to maintain a WT and/or whether to establish WLAN aggregation for the UE when the UE moves to a first radio access network; and, the second radio access network node transmits information about whether to maintain the WT and/or indication information about whether to establish the WLAN aggregation for the UE.

  • Patent number: 11553389
    Abstract: This application provides a method for controlling a terminal to use a wireless network, a system, and a related device. The method includes: obtaining, by a network decision device, service information of a terminal, constructing network use indication information, and delivering the network use indication information to a network trigger device; and triggering, by the network trigger device based on the network use indication information, the terminal to use a wireless network corresponding to the service information. According to the method, an operator can assign, based on a service requirement of the operator, the terminal to use a specific wireless network, so that the terminal can use in time a wireless network that is consistent with a requirement of the operator. This helps improve network use efficiency for the operator, and can prevent a service of the terminal from being affected.

  • Patent number: 11553548
    Abstract: Various arrangements for performing intelligent cellular channel management are presented herein. A physical cellular communication channel may be established between a user equipment (UE) and a cellular network for sending a short message service (SMS) message in response to a cellular service request from the UE. One or more characteristics of the UE, the SMS message, or both may be analyzed. A duration of time for which the physical cellular communication channel is kept active may be based on the analyzed one or more characteristics. A channel maintenance instruction may be transmitted to keep the physical cellular communication channel active based on a cellular network messaging controller determining to adjust the duration of time for which the physical cellular communication channel is kept active.

  • Patent number: 11546722
    Abstract: A User Equipment (UE) device, such as a cellular telephone, configured to store Higher Priority Public Land Mobile Network (HPPLMN) timer setting values and enterprise geofence information associated with the entries on its Equivalent Home Public Land Mobile Network (EHPLMN) list is disclosed. When the UE is camped on an EHPLMN, the UE may search/scan for higher priority EHPLMNs using the HPPLMN timer setting values associated with the entries on the list that have higher priority than the current EHPLMN. The rate of the scans may be set based on the shortest HPPLMN timer entry of the higher priority entries on the EHPLMN list. The UE may also or instead be configured to search for geofenced EHPLMNs on the list for which entrance criteria are currently satisfied, even when the current EHPLMN has higher priority than the geofenced EHPLMNs.

  • Patent number: 11540186
    Abstract: When frequency range 1 (FR1) (e.g., Sub6 Ghz radio coverage), and FR2 (e.g., mmW coverage) are present in a given area, there can be a broader coverage from FR1 broadcasting in addition to targeted coverage from FR2 broadcasting. Consequently, FR1 can overlap FR2. To generate system efficiencies, the FR1 and FR2 spectrums can be combined by carrier aggregation (CA) and/or dual connectivity (DC). Thus, a hybrid approach can combine use of both CA and DC, based on radio access network instructions and radio frequency conditions experienced by a user equipment device as it transitions between CA and DC coverage areas.
