Abstract:
A method for implementing Customized Ringing Signal (CRS) services is provided. The method includes: receiving a call request initiated by a caller terminal; obtaining a policy of playing a CRS tone according to the call request, where the policy is a policy of playing a CRS tone, namely, a caller CRS tone or a callee CRS tone, or a policy of filtering the CRS tone; and playing the CRS tone to a callee according to the policy. By setting a policy of playing the CRS tone to the callee in the network or the callee terminal, the users enjoy the CRS services at their own discretion.

This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A first network device receives energy saving information of M cells from a second network device, and sends second request information to the second network device based on the energy saving information of the M cells, where the second request information is for requesting to add N cells in the M cells to a secondary cell group of a terminal device. According to the method, the first network device may determine, based on the energy saving information of the M cells of the second network device, whether to request to add the second network device as a secondary network device of the terminal device.
Abstract:
A method, device and system for authenticating gateway, node and server are provided in this invention. The node receives a message sent by a gateway, wherein the message comprises a number T3 shared by the gateway and a server, and a gateway identification. The node encrypts data with a key K1 shared by the node and the server, the data including T3, the gateway identification, and a random number T1 generated by the node, and then sends the encrypted data and a node identification to the server through the gateway. The node decrypts data encrypted by the server and forwarded by the gateway with the key, determines that the server is a valid server according to a T1-related number obtained by decryption, and establishes a security channel with the gateway according to a new key obtained through the decryption.
Abstract:
This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A network device determines energy saving information of a first cell, where the energy saving information indicates a compensation value corresponding to a first energy saving state, and when the first cell is in the first energy saving state, the compensation value is used to compensate a measurement value of an SSB associated with the compensation value; and sends the energy saving information to a terminal device. According to the method, the network device may perform an energy saving operation on the SSB (for example, reducing a transmit power of the SSB), and send the energy saving information of the first cell to the terminal device.
Abstract:
A method for performing an operation on a device resource includes: receiving a first request, which is requests an operation on a device resource, where a destination address of the first request is a mapped address of the device resource on a management apparatus; determining, that the device resource is created on a device corresponding to the device resource; generating a second request for performing an operation on the device resource on the device; and transmitting the second request to the device. A management apparatus for performing an operation on a device resource is also provided. By using the present invention, the complexity for the network application to perform an operation on the device resource can be reduced, and the convenience for the network application to perform an operation on the device resource can be improved. Therefore, extensive application of M2M can further be promoted.
