Abstract
A method, performed by an access point of a cellular network, obtains time information by identifying a control channel cycle boundary; at a beginning of the control channel cycle boundary, sending a request to a time server; receiving a response from the time server, the request including a server time; and obtaining the timing information using the server time. Obtaining the timing information includes using the server time and a first reference time to obtain an integer and a fraction; using the fraction to obtain a time difference; and using the time difference to obtain the timing information.

A method, performed by an access point of a cellular network, for obtaining time information, the method comprising:
- identifying a control channel cycle boundary;
- at a beginning of the control channel cycle boundary, sending a request to a time server;
- receiving a response from the time server, the request comprising a server time;
- and
- obtaining the timing information using the server time.
A method, performed by an access point of a cellular network, for obtaining time information, the method comprising:
- identifying a control channel cycle boundary;
- at a beginning of the control channel cycle boundary, sending a request to a time server;
- receiving a response from the time server, the request comprising a server time;
- and
- obtaining the timing information using the server time;
- wherein obtaining the timing information comprises:
- using the server time and a first reference time to obtain an integer and a fraction;
- and
- using the integer to obtain the timing information.
One or more machine-readable storage media comprising instructions that are executable by an access point of a cellular network to obtain time information, the instructions for:
- identifying a control channel cycle boundary;
- at a beginning of the control channel cycle boundary, sending a request to a time server;
- receiving a response from the time server, the request comprising a server time;
- and
- obtaining the timing information using the server time.
