Embodiment
The characteristics of in order to more fully hereinafter understand the embodiment of the present invention and technology contents, below in conjunction with the accompanying drawings to this hair The realization of bright embodiment is described in detail, appended attached drawing purposes of discussion only for reference, is not used for limiting the embodiment of the present invention.
As it was previously stated, on the premise of multiple RAT systems degree of coupling are higher, can occur to the access procedure of UE abnormal. For this reason, an embodiment of the present invention provides a kind of network refusal terminal access LTE network, and forbid accessing all in tracking area Under the scene of LTE cells, the detection method of network insertion result.
In various embodiments of the present invention, during terminal performs LTE network access using default prioritization scheme, Receive the first Attach Request message that TAC of the terminal based on the first LTE cells is sent;Determine the first LTE cells There is not corresponding cell in the corresponding tracking areas of TAC, attachment refuse information is sent to the terminal;Receive the terminal and be based on the The second Attach Request message that two LTE cells TAC are sent, attachment success message is sent to the terminal;The 2nd LTE cells TAC and the TAC of the first LTE cells differ;Resident state of the terminal in the 2nd LTE cells is detected, and Determine whether the terminal is successfully accessed LTE network based on testing result.

Fig. 1 is the detection method flow diagram that LTE network provided in an embodiment of the present invention accesses result, the present embodiment During technical solution is applied to terminal using the execution LTE network access of default prioritization scheme, as shown in Figure 1, the net The detection method of network access result includes:
Step 101:Receive the first Attach Request message that TAC of the terminal based on the first LTE cells is sent;
Wherein, first Attach Request message is sent after the terminal selects the first LTE cells;Described first There is not corresponding cell in the corresponding tracking areas of TAC of LTE cells.It is worth noting that, attachment is performed between terminal and network The premise of process is that terminal completes wireless heterogeneous networks (RRC, Radio Resource Control) connection with network and establishes Process.
Specifically, the RRC connection request that terminal is sent to network side, the lateral terminal of network return to RRC connection establishment responses Message;Terminal sends RRC connection setup complete messages to network side.
That is, before the terminal and network side carry out attaching process, the terminal needs to carry out with network side Random access procedure.
More specifically, random access procedure can include:Terminal sends random access request message (Msg1) to base station, its It is middle to carry leading (preamble);After base station receives message, accidental access response message (Msg2) is sent to terminal;Terminal receives After message, send RRC connections to base station and establish request message (Msg3);After base station receives message, send RRC connections to terminal and build Vertical message (Msg4);Terminal sends RRC connection setup complete messages (being sent by SIB1) to base station.
Step 102:Determine there is not corresponding cell in the corresponding tracking areas of TAC of the first LTE cells, to the end End sends attachment refuse information;
Here during practical application, after LTE base station receives the first Attach Request message of terminal transmission, institute is forwarded to MME State the first Attach Request message.The attachment relevant treatment in LTE network is carried out to the terminal by MME and HSS, including authenticate, Location management etc., to complete to register in LTE network, when mobile etc. due to terminal, causes TAC pairs of the first LTE cells When not having corresponding cell in the tracking area answered, MME sends attachment refuse information by LTE base station to terminal.
Wherein, tracking area is LTE/ System Architecture Evolutions (SAE, System Architecture Evolution) system The concept newly set up for the location management of terminal.It is defined as UE need not more new demand servicing move freely region.Tracking area Function can be divided into paging management and location updating management to realize the management to terminal location.Terminal is registered by tracking area and accused Know core net (EPC) tracking area of itself.
When terminal is in idle condition, core network is able to know that the tracking area where terminal, while when in the free time When the terminal of state needs to be paged, it is necessary to paged in all cells for the tracking area that terminal is registered.Tracking area is small The configuration of area's level, multiple cells can configure identical tracking area, and a cell can only belong to a tracking area.
Wherein, in one embodiment, encapsulation attachment refuse information, it is described to adhere in refuse information the original for carrying attachment refusal Because of value, the reason for adhering to refusal value is used for the reason for table attachment is refused;
Wherein, the reason for attachment in the attachment refuse information is refused value is used to trigger the terminal based on described 2nd LTE cells perform attaching process.
That is, the reason for attachment of the terminal in the exhausted message of attachment is refused value determines that attachment is lost Lose, so as to perform attaching process based on the 2nd LTE cells, i.e., sending the second attach request to the 2nd LTE cells disappears Breath, to initiate attaching process, that is, performs step 103.
Step 103:The second Attach Request message that the terminal is sent based on the 2nd LTE cells TAC is received, to the end End sends attachment success message;
Here, second Attach Request message is sent after the terminal selects the 2nd LTE cells;Described The TAC of two LTE cells and the TAC of the first LTE cells are differed.
In one embodiment, after receiving the second Attach Request message that the terminal is sent, the terminal is authenticated, Obtain authentication successful result;
Default EPS bearing (defaultEPSBearer) is established for the terminal, to complete attaching process;
Attachment success message is sent to the terminal.
Wherein, EPS carrying the transmission data and/or signaling etc. of foundation.
During practical application, in order to verify the validity of prioritization scheme, can also detect the terminal receive attachment refusal disappear Behavior after breath, further to verify the validity of prioritization scheme and reasonability.
Based on this, in one embodiment, after sending attachment refuse information to the terminal, judge whether received in preset duration The second Attach Request message sent to the terminal;
If the terminal transmission is received in preset duration second adheres into request message, sent to the terminal Adhere to success message.
Wherein, it is described to judge the second Attach Request message that the terminal is sent whether is received in preset duration, including:
Detect whether the terminal is initiated in the first preset duration to the first LTE cells or to the first GSM cell Access request;The TAC of first GSM cell is identical with the TAC of the first LTE cells;
Do not initiated in the first preset duration to the first LTE cells or the access request to GSM cell when detecting When, judge whether the terminal receives the second Attach Request message that the terminal is sent in the second preset duration.
Here, when detecting in the first preset duration initiate to the first LTE cells or to the first GSM cell During access request, illustrate that prioritization scheme fails.
Certainly, when the terminal does not receive the second Attach Request message of the terminal transmission in the second preset duration When, also illustrate that prioritization scheme fails.
During practical application, first preset duration and the second preset duration can be real by way of setting timer It is existing;Specifically, first timer is set, and whether the detection terminal is initiated to described first before first timer time-out LTE cells or the access request to the first GSM cell;Second timer is set, when the detection before first timer time-out To the terminal do not initiate to the first LTE cells pair or during to the access request of the first GSM cell, it is fixed described second When device time-out before the detection terminal whether receive the second Attach Request message that the terminal is sent.Wherein, timer is set Purpose be avoid detection overlong time.
Wherein, the duration of timer can be arranged as required to.
Step 104:Resident state of the terminal in the 2nd LTE cells is detected, and institute is determined based on testing result State whether terminal is successfully accessed LTE network.
In one embodiment, at step 104, when detecting that the terminal can reside in the 2nd LTE cells, Determine that the terminal is successfully accessed LTE network, further illustrate prioritization scheme success.
Certainly, when detecting that the terminal can not reside in the 2nd LTE cells, the terminal access is illustrated LTE network fails, and further illustrates prioritization scheme failure.
Wherein, during practical application, detect the terminal whether can reside in the 2nd LTE cells situation have it is following Two kinds:
The first situation, the terminal are completed to adhere in the 2nd LTE cells, i.e., after registration process, in this case Timer can be set, detect whether the terminal can reside in the 2nd LTE cells before timer expiry, if fixed When device time-out before detect that the terminal resides in the 2nd LTE cells, and when not initiating access request to other cells, Illustrate that the terminal can stably reside in the 2nd LTE cells;If detect the terminal before timer expiry When initiating access request to other cells, illustrate that the end can not stably reside in the 2nd LTE cells.
The second situation, when the first situation detects that the terminal can reside in the 2nd LTE cells, when described When the transmission power of second GSM cell is higher than the transmission power of the 2nd LTE cells, detect whether the terminal can be resident In the 2nd LTE cells, if the terminal resides in the 2nd LTE cells, and do not initiated to second GSM cell During access request, illustrate that the terminal can stably reside in the 2nd LTE cells;If the terminal is to described two When GSM cell initiates access request, illustrate that the terminal can not stably reside in the 2nd LTE cells.Wherein, it is described The TAC of second GSM cell is identical with the TAC of the 2nd LTE cells.
