Description
Technical field
The present embodiments relate to fields of communication technology, and in particular to a kind of cut-in method and terminal.
Background technique
(Long Term Evolution, long term evolution agreement regulation, before safe activation, part NAS is (non-access by LTE
Layer) signaling is not necessarily to integrity protection, chance is provided to the development of 4G (fourth generation mobile communication technology) pseudo-base station.4G is pseudo- at present
Base station large scale deployment centainly influences in the crowded region and high speed crossing of various regions to user's communication band；Due to 4G
Bi-directional authentification and integrity protection so that 4G pseudo-base station can not implement to monitor for a long time to user and attack, and 4G+GSM is (complete
Ball mobile communication system) scheme of pseudo-base station cooperation brings very big hidden danger to user security, and then causes to issue pseudo-base station note
Feasibility.
A kind of working method of existing 4G+GSM pseudo-base station is as follows:
1) 4G pseudo-base station setting CI (cell identification) identical with cell adjacent area where user, different TAI (tracking area knowledge
Other code), biggish transmission power cause terminal occur gravity treatment and TAU (tracing section updating) request；
2) RRC (wireless heterogeneous networks) connection is established, terminal initiates RRC connection and establishes request (RRC Connection
Request), pseudo-base station replys RRC Connection Reject (refusal), and the inside includes deprioritisationReq
IE, instruction GSM access priority are higher than LTE；
3) GSM pseudo-base station is opened, existing net cell CI is imitated, opens high-power and larger reselecting parameters CRO (the cell weight of setting
Choosing biasing)；
4) terminal accesses GSM pseudo-base station, pseudo-base station transmitting short message.
The depriorityReq IE that wherein RRC Connection Reject message carries is optionally, can to indicate
Access priority makes terminal pay the utmost attention to other networks, such as GSM when searching for network according to IE.
Common has the reason of causing RRC Connection Reject (RRC connection refusal):
Cell code channel inadequate resource is UE (terminal) distribution without enough code channels；
Interference or power limited, soft resources receive failure；
Transfer resource application or bandwidth admission failure.
Multi-user's cell admission control situation will issue the instruction.
Other common 4G terminals access GSM pseudo-base station schemes include in TAU Reject message or RRC
Instruction etc. is redirected comprising GSM in Connection Release (RRC Connection Release), is organized a discussion at present in 3GPP etc.
Relevant precautionary scheme, for example do not receive to indicate GSM frequency point in RRC Connection Release after TAU Reject, and
Method above-mentioned by RRC Connection establish Reject is capped not yet, leads to terminal still
Access GSM pseudo-base station may be induced by 4G pseudo-base station.
