Method and apparatus for processing messages received by a device from a network
View Patent ↗A method and apparatus for processing messages received by a device from a network. The method comprises receiving a message that indicates that the device should be in a dedicated channel state (such as Cell_DCH), wherein the message is a message other than a reconfiguration message (e.g. CUC) and, in response to the message, clearing from the device any record of a cell identifier (C_RNTI).
1. A method of processing messages received by a-User Equipment (UE), the UE configurable to be operable in a cellular network, the method comprising:
receiving one of the following messages: a Cell Update Confirm message; or, a Universal Mobile Telecommunication System Terrestrial Access Network Registration Area, Update Confirm message; or, a Radio Resource Control Connection setup message;
clearing from the UE any record of a cell identifier that at least temporarily identifies a cell on receipt of one of the messages received during said receiving, and, if the received message includes a new cell identifier, not storing the included cell identifier in the UE;
moving to a dedicated channel state; and
optionally sending a response message configured to be receivable by the network after the UE is cleared of any record of a cell identifier.
2. A method according to claim 1 wherein the dedicated channel is a Cell_DCH channel.
3. A method according to claim 1 wherein the cell identifier is a Cell Radio Network Temporary Identifier.
4. A User Equipment (UE) device, the UE configurable to be operable in a cellular network, the UE comprising:
a memory and a processor configurable to:
receive one of the following messages: a Cell Update Confirm message; or, a Universal Mobile Telecommunication System Terrestrial Access Network Registration Area, Update Confirm message; or, a Radio Resource Control Connection setup message;
clear from the memory any record of a cell identifier that at least temporarily identifies a cell or receipt of a received message, and, if the received message includes a new cell identifier, not storing the included cell identifier in the memory;
move to a dedicated channel state; and
send, optionally, a response message configured to be receivable by the network after memory is cleared of any record of a cell identifier.
5. The UE of claim 4 wherein the dedicated channel is a Cell_DCH channel.
6. The UE of claim 4 wherein the cell identifier is a Cell Radio Network Temporary Identifier.
7. A method of processing messages received by a User Equipment (UE), the UE configurable to be operable in a cellular network, the method comprising:
receiving one of the following messages: a Cell Update Confirm message; or, a Universal Mobile Telecommunication System Terrestrial Access Network Registration Area, Update Confirm message; or, a Radio Resource Control Connection setup message;
clearing from the UE any record of a cell identifier that at least temporarily identifies a cell on receipt of a received message, and, if the received message includes a new cell identifier, ignoring the included cell identifier;
moving to a dedicated channel state; and
optionally sending a response message configured to be receivable by the network after said clearing.
8. A method according to claim 7 wherein the dedicated channel is a Cell_DCH channel.
9. A method according to claim 7 wherein the cell identifier that at least temporarily identities the cell comprises a Cell Network Temporary Identifier.
