Claim:
1. A method in a base station for managing access to a first contention based channel and a second contention based channel, the method comprising: encoding system information directly indicating first access request preambles for the first contention based channel, and indirectly indicating second access request preambles for the second contention based channel based on the directly indicated first access request preambles; and broadcasting the encoded system information to mobile terminals; wherein the encoding comprises encoding system information that indicates a second available resource of the second contention based channel relative to a first available resource of the second contention based channel; wherein the system information that indicates the second available resource of the second contention based channel relative to the first available resource of the second contention based channel is encoded in an ordered list that defines common Enhanced-Dedicated Channel (E-DCH) resources; wherein each E-DCH Resource is defined by a Soffset information element, a Fractional Dedicated Physical Control Channel (F-DPCH) code number information element, and an E-DCH Hybrid Automatic Repeat Request Acknowledgement Indicator Channel (E-HICH) info for common E-DCH information element; and wherein the position of the second available resource in the ordered list is defined by a default value in the Soffset information element, wherein the default value is a function of the position of the second available resource within the ordered list, a function of a “Soffset” value of a previous first available resource, or a function of the position of the second available resource and an offset value that is a Soffset value of the first available resource.
