Signalling radio service requirements
View Patent ↗A method of establishing transmissions to a mobile station in a wireless radio communications system where an indication of the radio service requirement is provided to the mobile terminal. A switch receives a signal originating a call. The switch notifies a network accordingly with a paging message. The paging message is supplied to the mobile station. The indication of the radio service requirement is provides as part of, or with, the paging message. Subsequently, only those cells that fulfil the radio service requirement need be measured to determine which one is to be used for the transmission.
1. A method of establishing a transmission to a mobile station via a radio network, the method comprising:
providing a paging message to the mobile station;
providing an indication of a radio service requirement to the mobile station,
wherein said paging message comprises the indication of the radio service requirement, and
wherein said radio service requirement comprises an indication of a desired amount of at least a first network resource, wherein the mobile station uses the indication of the radio service requirement when making access to the radio network to measure only cells capable of meeting the radio service requirement in order to select one of them for use in the transmission.
2. A method as claimed in claim 1 , wherein the indication of the radio service requirements comprises properties of the cell capable of fulfilling the radio service requirement.
3. A method as claimed in claim 2 , wherein the indication of the radio service requirements comprises the required bandwidth of a cell.
4. A method as claimed in claim 1 , wherein the indication of the radio service requirement comprises the radio service requirement.
5. A method as claimed in claim 1 , wherein the indication of the radio service requirements comprises at least a portion of at least one access value.
6. A method as claimed in claim 5 , wherein the mobile station returns the at least one access value to the radio network on an access channel.
7. A method as claimed in claim 6 , wherein the access channel is a random access channel.
