1633 * V1.3.1, which is GMR-1 04.008, not to be confused with GMR-1
1634 * 3G 44.008), saying some messages are the same as in GMR-1
1635 * 04.008. [1]:
1636 *
1637 * says, in 10.1.18.2, that "Extended immediate assignment"
1638 * "is sent on the main signalling link by the network to
1639 * the MES in response to an EXTENDED CHANNEL REQUEST message
1640 * by the MES";
1641 *
1642 * says, in 10.1.20.2, that "Immediate assignment reject type 2"
1643 * "may be sent to the MES by the network on the CCCH to indicate
1644 * that no channel is available for assignment or that the MES
1645 * cannot be allowed access";
1646 *
1647 * says, in 10.1.20.3, that "Extended immediate assignment
1648 * reject" "message is sent by the network on the DCCH to
1649 * indicate that no channel is available for assignment or
1650 * that the MES cannot be allowed access";
1651 *
1652 * does not mention "Immediate assignment type 2" anywhere
1653 * that I can see.
1654 *
1655 * [3]:
1656 *
1657 * says, in 10.1.18.2, that "Extended immediate assignment
1658 * (A/Gb mode only)" is "Same as clause 10.1.18.2 of
1659 * GMR-1 04.008";
1660 *
1661 * says, in 10.1.18.3, that "Intermediate assignment Type
1662 * 2 (A/Gb mode only)" "is sent on the CCCH by the network
1663 * to the MES to change the channel configuration to a
1664 * dedicated configuration while staying in the same cell";
1665 *
1666 * says, in 10.1.20.2, that "Immediate assignment reject
1667 * type 2" is "Same as clause 10.1.20.2 of GMR-1 04.008";
1668 *
1669 * says, in 10.1.20.3, that "Extended immediate assignment
1670 * reject" is "Same as clause 10.1.20.3 of GMR-1 04.008".
1671 *
1672 * This is currently handled by ORing 0x100 into the values
1673 * for the DCCH, and, in gmr1_get_msg_rr_params(), if the dcch
1674 * parameter is set (which it is if called from gmr1_get_msg_params()
1675 * in packet-gmr1_common.c), 0x100 is ORed into the value
1676 * passed to try_val_to_str_idx(). If that returns NULL, or
1677 * isn't called in the first placee, it calls try_val_to_str_idx()
1678 * without ORing in 0x100.
1679 *
1680 * So that's why a 1-byte field has, in a value_string used with
1681 * it, two values that don't fit into 1 byte.
1682 *
1683 * It Would Be Nice if this could be done in a somewhat less
1684 * hackish and opaque fashion.
