Method and apparatus of informing UE access barring
View Patent ↗A method of informing a user equipment about access barring includes the steps of: determining a bit set for the access barring, wherein the bit set includes at least two bits and discloses at least whether the access barring is on or off; placing at least a first bit of the bit set in a starting message, the starting message being one the following messages: a master information block message or a paging message; and transmitting the bit set in a message set via radio interface to the user equipment, the message set including at least the starting message. The starting message may disclose whether the remaining access barring information need to be read.
1. A method of informing a user equipment about access barring, the method comprising the steps of:
determining a bit set for the access barring, wherein the bit set includes at least two bits and discloses at least whether the access barring is on or off;
placing at least a first bit of the bit set in a starting message, the starting message being a paging message; and
transmitting the bit set in a message set via a radio interface to the user equipment, the message set including at least the starting message, the method further comprising;
transmitting a system information block via the radio interface to the user equipment, the system information block comprising a scheduling information list that lists a further system information block that contains access barring information.
2. The method according to claim 1 , wherein the step of determining the bit set comprises the sub-step of:
setting values into the bit set so that the bit set discloses at least one of access classes 0-9 to be barred.
3. The method according to claim 1 , wherein the step of determining the bit set comprises the sub-step of:
setting values into the bit set so that the bit set discloses at least one of access classes 0-9 to be released.
4. The method according to claim 1 , wherein the step of determining the bit set comprises the sub-step of:
setting values into the bit set so that the bit set includes a category parameter, the category parameter disclosing at least one category of categories A, B, and C to which the access barring is applied.
5. The method according to claim 1 , wherein the step of determining the bit set comprises the sub-step of:
setting values into the bit set so that the bit set includes a network parameter, the network parameter disclosing at least one public land mobile network to which the access barring is applied.
6. The method according to claim 1 , wherein the step of determining the bit set comprises the sub-step of:
setting values into the bit set so that the bit set includes a domain parameter disclosing a domain set to which the access barring is applied; the domain set including at least one of the following domains: a circuit switched domain, a packet switched domain.
7. The method according to claim 1 , wherein the step of determining the bit set comprises the sub-step of:
setting values into the bit set so that the bit set discloses information of the access barring to be updated.
8. An apparatus for informing a user equipment about access barring, the apparatus comprising:
at least one processor; and
at least one memory including computer program code,
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
determine a bit set for the access barring, wherein the bit set includes at least two bits and discloses at least whether the access barring is on or off;
place at least a first bit of the bit set in a starting message, the starting message being a paging message;
transmit the bit set in a message set via a radio interface to the user equipment, the message set including at least the starting message; and
transmit a system information block via the radio interface to the user equipment, the system information block comprising a scheduling information list that lists a further system information block that contains access barring information.
9. The apparatus according to claim 8 , wherein the apparatus is caused to perform:
setting values into the bit set so that the bit set includes a category parameter, the category parameter disclosing at least one category of categories A, B, and C to which the access barring is applied.
10. The apparatus according to claim 8 , wherein the apparatus is caused to perform:
setting values into the bit set so that the bit set discloses information of the access barring to be updated.
11. An apparatus for determining information about access barring, the apparatus comprising:
at least one processor; and
at least one memory including computer program code,
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
receive a message set transmitted via a radio interface to a user equipment, the message set including at least a starting message that is a paging message;
obtain at least a first bit of a bit set from the starting message, wherein the bit set includes at least two bits and is intended for access barring;
determine information of the bit set; the information at least disclosing whether the access barring is on or off; and
receive a system information block transmitted via the radio interface to the user equipment, the system information block comprising a scheduling information list that lists a further system information block that contains access barring information.
12. The apparatus according to claim 11 , wherein the apparatus is caused to perform:
determining on the basis of values of the bit set that at least one of access classes 0-9 is barred.
13. The apparatus according to claim 11 , wherein the apparatus is caused to perform:
determining on the basis of values of the bit set that at least one of access classes 0-9 is released.
14. The apparatus according to claim 11 , wherein the apparatus is caused to perform:
detecting in the bit set a category parameter, the category parameter disclosing at least one category of categories A, B, and C to which the access barring is applied.
15. The apparatus according to claim 11 , wherein the apparatus is caused to perform:
detecting in the bit set a network parameter, the network parameter disclosing at least one public land mobile network to which the access barring is applied.
16. The apparatus according to claim 11 , wherein the apparatus is caused to perform:
detecting in the bit set a domain parameter, the domain parameter disclosing a domain set to which the access barring is applied; the domain set including at least one of the following domains: a circuit switched domain, a packet switched domain.
17. The apparatus according to claim 11 , wherein the apparatus is caused to perform:
determining on the basis of the bit set that the access barring is updated.
