A mobility management switching center is for communicating with user equipment of a communication system that supports LTE or 3G, the mobility management switching center including a receiver that receives a session management signal from the user equipment; and a transmitter that transmits, when the session management signal is received, a restriction signal for instructing not to transmit a new session management signal to the user equipment.

An information processing method is provided for a mobile terminal. The method includes obtaining a first identity identifier assigned to a terminal by a network side; in response to loading the first identity identifier and, from a plurality of identity identifiers of the terminal, determining a second identity identifier as an identity identifier of the terminal in a first operation state; obtaining, based on the second identity identifier, information used for registering and connecting with a second communication network; establishing a data connection between the first identity identifier and the first communication network; and on the data connection established between the first identity identifier and the first communication network, registering with the second communication network using the information for registering and connecting with the second communication network.

A mobile communication system includes a control device and a base station device. Data communication between the control device and the base station device is conducted using a fixed-length data size and a variable-length data size. The control device transmits information indicating whether a data size of the data communication has a fixed length or a variable length. The base station device receives the information from the control device.

A system configured to analyze cellular connectivity information for at least one wireless network and at least one wireless device includes a processor configured to receive cellular connectivity information from at least one wireless network for at least one wireless device; the processor further configured to receive geographic location information from the at least one wireless network for the at least one wireless device. The system also includes a database configured to store the cellular connectivity information, the geographic location information, and equipment type information related to the at least one wireless device. The processor further configured to analyze the cellular connectivity information and determine a wireless device having poor wireless service performance based on the analysis of the cellular connectivity information. The disclosure additionally includes a process to analyze cellular connectivity information for at least one wireless network and at least one wireless device.

A communication device may be configured to access a plurality of subscriptions for a plurality of providers. For example, a communication device may be configured with at least one subscriber identity module (SIM). For a communication device having a plurality of subscriptions accessible thereto, the selection of a subscription to connect to a destination network may be configurable. The selection of a subscription from a plurality of available subscriptions may be based on a cost (e.g., financial cost, data cost, or another resource) associated with connecting to a destination network using different subscriptions. For example, a first subscription may be selected if connection to the destination network is more expensive using a second subscription and/or if the balance on the second subscription is too low.

Implementation of an application rule for an application to be accessed by a User Equipment, UE, in a user session in a Service Based Architecture, SBA, domain in a core network of a telecommunications system is disclosed. The SBA, among others, comprises a Policy Control Function, PCF (6), an Application Function, AF (5), and a Session Management Function, SMF (9). The method comprising the steps of receiving, by the PCF (6), an application rule comprising an AF Identifier, AF-ID, identifying the application rule, an Application Identifier, App-ID, identifying the application, and at least one service requirement for processing the application in the SBA domain. The PCF (6) instructing the SMF (9) to execute the at least one service requirement to all present and future user sessions pertaining to the respective application. Complementary methods of supporting the execution of the application rule and devices are also presented.

Disclosed is a method for a terminal transmitting a sidelink data channel in a wireless communication system. Particularly, the method comprises a step for transmitting a sidelink data channel having a first priority. The sum if resources which can be used for all sidelink data channels having a priority equal to or lower than the first priority is equal to or less than a threshold corresponding to the first priority.
