摘要： Solutions for providing a data traffic session with proxy-call session control function (P-CSCF) restoration include: receiving an indication, by an application server (AS), that a user equipment (UE) is registered with a first proxy node; receiving, at a subscriber information node, from a call session control function (e.g., over an N70 interface), a first message triggering proxy node restoration; based on at least receiving the first message triggering proxy node restoration, transmitting, by the subscriber information node, to a management node, a second message triggering proxy node restoration; receiving an indication, by the AS, that the UE is registered with a second proxy node different than the first proxy node; and based on at least receiving a session initiation message, establishing the data traffic session for the UE with the second proxy node.

摘要： Methods, devices, and system related to adaptive determination of payload sizes based on usage patterns of the contents are disclosed. In one example aspect, an apparatus for wireless communication includes a processor that is configured to transmit a first data packet associated with a first network content to a user device, receive a request from the user device indicating a switch to a second network content from the first network content, determine a usage pattern associated with the first network content based on information included in at least the first data packet and the request, and adaptively change, based on the usage pattern, a payload size of a second data packet associated with a subsequent transmission of the first network content.

摘要： Methods, devices, and systems related to wireless communications are disclosed. In one example aspect, a device for wireless communication includes a processor that is configured to receive an enquiry message from a base station enquiring capability information of the terminal device and transmit a response message to the base station indicating one or more templates of capability information determined according the one or more radio access technologies and a list of frequency bands.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for implementing a spam telephone call reducer are disclosed. In one aspect, a method includes the actions of receiving first telephone call data that reflects telephone calls received by a first user and second telephone call data that reflects telephone calls received by a second user. The actions further include comparing the first telephone call data and the second telephone call data. The actions further include determining that the first user received more spam telephone calls than the second user. The actions further include determining a first characteristic of the first user and a second characteristic of the second user. The actions further include determining an action that increases a similarity of the first characteristic to the second characteristic. The actions further include performing the action on the first characteristic.

摘要： This disclosure describes techniques for determining technological capability of devices whose technological capability are unknown. The devices can be users of a wireless telecommunication network. A device, such as a cell phone, has a type allocation code (TAC) which can indicate a make and model of the device. Once the make and model of the device are known, the technical capability of the device is known. Certain TAC numbers, however, do not indicate the make and model of the device, and thus a device's technical capability is unknown. To determine the technological capability of the devices, a machine learning model is trained using usage data of the devices with known technological capability. After training, the machine learning model can be deployed to predict the technological capability of devices with unrecognizable TAC numbers by providing usage data associated with the devices with unrecognizable TAC numbers.

摘要： The methods, systems, and computer readable media discussed herein are directed to maintaining status information of network functions (NFs) associated with one or more network function repository functions (NRFs). An NRF, which may be one of a plurality of NRFs belonging to a group of NRFs, maybe queried. The plurality of NRFs may be synchronized to each other, and the group of NRFs may be one of a plurality of groups of NRFs. One or more NFs may be registered with the NRF, and each NRF of the plurality of NRFs may have one or more corresponding NFs registered to it. The NRF may maintain status information of the one or more NFs registered to the NRF. The NRF may collect information associated with querying of NFs by another NF, and send statistical data based on the collected information to a user interface (UI) of an external device to be displayed on the UI.

摘要： In some examples, a terminal can establish wireless communication with a base station. The terminal can determine a challenge, transmit the challenge, receive a response, and determine that the response is valid. The terminal can, in response, establish a secure network tunnel to a network node. In some examples, a terminal can determine a first communication parameter associated with communication with the base station. The terminal can receive data indicating a second communication parameter via a secure network tunnel. The terminal can determine that the communication parameters do not match, and, in response, provide an indication that an attack is under way against the network terminal. Some example terminals transmit a challenge, determine a response status associated with the challenge, and determine that an attack is under way based on the response status.

摘要： In a 5 th -Generation (5G) cellular communication network, charging customers for data usage is performed by a network function referred to as a charging function (CHF). A session management function (SMF) of the network repeatedly sends update requests to reserve additional data for a data session. If the CHF is not available and the SMF does not receive a response to an update message, the SMF continues to assign data for the data session, even though it has not received authorization to do so from the CHF. When the CHF becomes available, the SMF sends a request to start a second data session to continue the data connection that was previously supported by the original data session. This request specifies the amount of data that was used in the original data session without being confirmed by the CHF, allowing the CHF to account for this data usage.

摘要： Various systems, methods, and devices relate to determining a delay associated with a device; calculating a guard time based at least in part on the delay; and scheduling a wireless resource to include a downlink interval, an uplink interval, and the guard time between the downlink interval and the uplink interval. By calculating the guard time based at least in part on the delay associated with the device, spectrum efficiency can be enhanced, and latency can be reduced.

摘要： Systems and methods are described herein for storing and/or retaining message object data for subscribers of a wireless network. The systems and methods introduce a storage architecture that retains message objects in both hot storage (or local storage) and cold storage (remote or archive storage), to comply with the OMA and/or GSMA standards. After certain events associated with the message objects occur, such as an expiration of a time-to-live (TTL) parameter for the message objects, the systems and methods purge or remove message objects from the local storage, but maintain the message objects in the remote storage location.
