Abstract: This application relates to communicating information between communication devices. A channel coding method is disclosed. A communication device obtains an input sequence of K bits. The communication device encodes the input sequence using a low density parity check (LDPC) matrix H, to obtain an encoded sequence. The LDPC matrix H is determined according to a base matrix and a lifting factor Z. The base matrix includes m rows and n columns, m is greater than or equal to 5, and n is greater than or equal to 27. The lifting factor Z satisfies a relationship of 22*Z≥K. According to the encoding method provided in the embodiments, information bit sequences of a plurality of lengths can be encoded for transmission between the communication devices.

Abstract: This application discloses an information processing method. A communication device obtains an input sequence. The input sequence has a quantity B of information bits. The communication devices transforms the input sequence into one or more code blocks. The communication device encodes each of the code blocks individually, to obtain one or more encoded code blocks. Each of the code blocks has a code block length less than or equal to a maximum code block length. Each of the code blocks includes a segment of the input sequence and may include one or more cyclic redundancy check (CRC) bits corresponding to the segment of the input sequence. The encoded code blocks can meet various channel coding requirements.

Abstract: A method can be implemented by a user equipment to update RPLMN information. A PLMN identifier is selected from an available PLMN identifier set that includes PLMN identifiers with RPLMN information, HPLMN information, UPLMN information, and OPLMN information separately. A location update request message that carries the PLMN identifier is sent to a mobile switching center. A TMSI reallocation command is acquired from the mobile switching center according to the location update request message. It is determined whether location update acceptance information that is returned by the mobile switching center according to the location update request message is currently acquired. An operation of updating the PLMN identifier to registered public land mobile network RPLMN information is performed when the location update acceptance information is acquired and the operation of updating the PLMN identifier to RPLMN information is skipped when the location update acceptance information is not acquired.

Abstract: A network registration method and apparatus, and a mobile terminal are presented. During re-registration with a network, after receiving a channel allocation rejection message sent by the network, a mobile terminal sorts all available frequency channels according to network resource statuses of frequency channels with which network registration failed before and that are in a low priority list. And then the mobile terminal tries to camp on all the available frequency channels according to an order of the sorting to determine a frequency channel to be camped on. The mobile terminal sends a network registration message to register with the frequency channel to be camped on.
