Grouping of user terminal cell access information in a system information block
View Patent ↗Disclosed is a method for generating and transmitting system information in a mobile radio cell. In said method, system information is grouped into several information frames, information required for a mobile user device in order to verify if said mobile user device has access to the mobile radio cell being grouped into a single information frame, and the information frames are fed to the data securing layer by the network layer and are transmitted by means of the physical layer.
1. A method for generating and transmitting system information in a mobile radio cell, the method comprising:
grouping system information to form several information blocks, wherein cell suitability information is grouped into a single suitability information block;
forming at least one information message from the information blocks;
supplying the at least one information message to a unit of the data link layer by a unit of the network layer; and
transmitting from the unit of the data link layer the at least one information message by at least one unit of the physical layer,
wherein the cell suitability information is information required for a mobile radio user device in order to verify whether the mobile radio user device is provided with access to the mobile radio cell and includes a Qrxlevmin information item, an item of information on the maximum permissible transmitting power on an uplink, a cell barred information item, an intrafrequency cell resolution indicator, a Qqualmin information item, a Tbarred parameter value, a cell reserved for operator use information item, and a cell reservation extension information item.
2. The method as claimed in claim 1 , wherein the information blocks are master information blocks or system information blocks.
3. The method as claimed in claim 2 , wherein the single suitability information block is a master information block of the master information blocks.
4. The method as claimed in claim 2 , wherein the single suitability information block is a system information block of the system information blocks.
5. The method as claimed in claim 1 , wherein the unit of the data link layer is a unit of a radio link control (RLC) layer.
6. The method as claimed in claim 1 , wherein the unit of the network layer is a unit of a radio resource control (RRC) layer.
7. The method as claimed in claim 1 , wherein the single suitability information block does not contain any other information.
8. The method as claimed in claim 1 , wherein the system information is transmitted by a base station which operates the mobile radio cell.
9. The method as claimed in claim 1 , wherein the unit of the data link layer is arranged in the base station.
10. The method as claimed in claim 1 , wherein the unit of the network layer is arranged in the base station.
11. The method as claimed in claim 1 , wherein the cell suitability information is associated with an identification, which enables the mobile radio user device to verify whether it has already stored the cell suitability information and which signals that the suitability information identified by the identification is currently valid in the mobile radio cell.
12. The method as claimed in claim 11 , wherein the identification is inserted into the single suitability information block.
13. The method as claimed in claim 11 , wherein the suitability information is provided with validity period information which specifies how long the identification for the information is valid.
14. The method as claimed in claim 1 , wherein cell suitability information further includes: a Local Area Code (LAC) and a Public Land Mobile Network (PLMN) identity.
15. The method as claimed in claim 1 , wherein the mobile radio cell is based on the Universal Mobile Telecommunications System (UTMS) standard.
16. The method of claim 1 , wherein the single suitability information block is a system information block type 1 (SIB1) information block.
17. A network device for generating and transmitting system information in a mobile radio cell, the network device comprising:
a grouping device to group system information to form several information blocks, wherein cell suitability information is grouped into a single suitability information block;
a generating device to form at least one information message from the information blocks;
a unit of the network layer configured to supply the at least one information message to a unit of the data link layer; and
the unit of the data link layer configured to transmit the at least one information message by means of at least one unit of the physical layer, wherein cell suitability information is information required for a mobile radio user device in order to verify whether the mobile radio user device is provided with access to the mobile radio cell and includes a Qrxlevmin information item, an item of information on the maximum permissible transmitting power on an uplink, a cell barred information item, an intrafrequency cell resolution indicator, a Qqualmin information item, a Tbarred parameter value, a cell reserved for operator use information item, and a cell reservation extension information item.
18. A method for verifying if a mobile radio user device is provided with access to a mobile radio cell, the method comprising:
determining into which single information block, out of a multiplicity of information blocks transmitted in the mobile radio cell, cell suitability information is grouped;
receiving the information block before other information blocks of the multiplicity of information blocks are received; and
verifying whether access to the mobile radio cell is provided for the mobile radio user device before other information blocks of the multiplicity of information blocks are received, wherein the cell suitability information is information required for the mobile radio user device to verify whether the mobile radio user device is provided with access to the mobile radio cell and includes a Qrxlevmin information item, an item of information on the maximum permissible transmitting power on an uplink, a cell barred information item, an intrafrequency cell resolution indicator, a Qqualmin information item, a Tbarred parameter value, a cell reserved for operator use information item, and a cell reservation extension information item.
19. A mobile radio user device, comprising:
a determining device to determine which single information block, out of a multiplicity of information blocks transmitted in a mobile radio cell, contains cell suitability information as grouped into a single suitability information block;
a receiving device configured to receive the single suitability information block before other information blocks of the multiplicity of information blocks are received; and
a testing device to verify whether access to the mobile radio cell is provided for the mobile radio user device before other information blocks of the multiplicity of information blocks are received, wherein cell suitability information is information required for the mobile radio user device to verify whether the mobile radio user device is provided with access to the mobile radio cell and includes a Qrxlevmin information item, an item of information on the maximum permissible transmitting power on an uplink, a cell barred information item, an intrafrequency cell resolution indicator, a Qqualmin information item, a Tbarred parameter value, a cell reserved for operator use information item, and a cell reservation extension information item.
