Abstract
System information is transmitted over an air interface between a node of a telecommunications network and a user equipment unit. The system information includes system information blocks which use extended system information block types, e.g., system information block type values which are outside a range of nominal system information block type values. The use of the extended system information block types is facilitated by embodiments of system information extension utility functions at the network node, by method of operating the network nodes, and by corresponding embodiments of system information processing functions provided at the user equipment unit.
Claims11
A node of a telecommunications network which prepares network system information for transmission across an air interface to a user equipment unit, the system information including a system information block type which is included in protocol blocks, the protocol blocks being a system information block and a referencing block, the referencing block being one or both of a master information block and a scheduling block, the protocol blocks in which the system information is included having a system information block type field which includes a system information block type value which corresponds to the system information block type, the system information block comprising one or more segments, the node is arranged to:
- include a first system information block type extension indicator in the system information block type field of the referencing block when the system information block type for a system information block referenced by the referencing block does not have a system information block type value in a nominal range of system information block type values;
- include a first system information block type extension field in the referencing block;
- include in the first system information block type extension field a system information block type extension value which indicates a system information block type for the system information block referenced by the referencing block;
- include a second system information block type extension indicator in the system information block type field of a segment of the system information block referenced by the referencing block;
- and,
- transmit a message containing additional network system information in said system information block associated with said system information block type extension value, whereby said user equipment unit can utilize said additional network system information for the management of radio resources.
A user equipment unit which receives network system information transmitted across an air interface from a network node, the system information including a system information block type which is included in protocol blocks, the protocol blocks being a system information block and a referencing block, the protocol blocks in which the system information is included having a system information block type field which includes a system information block type value which corresponds to the system information block type, the system information block including one or more segments, the user equipment is arranged to:
- receive a message containing network system information;
- recognize, in said message, a first system information block type extension indicator in the system information block type field of the referencing block when the system information block type for a system information block referenced by the referencing block does not have a system information block type value in a nominal range of system information block type values;
- locate a first system information block type extension field in the referencing block;
- obtain from the first system information block type extension field a system information block type extension value which indicates a system information block type for the system information block referenced by the referencing block;
- recognize a second system information block type extension indicator in the system information block type field of a segment of the system information block referenced by the referencing block;
- and,
- utilize additional system information in said system information block associated with said system information block type extension value for the management of radio resources of said user equipment unit.
