Abstract
The invention discloses a message transmitting method, a message transmitting device and a method for accessing a terminal to a PLMN. The message transmitting method includes the steps of enabling a base station to determine a first identification set of the PLMN allowing a terminal to be connected into, and enabling the first identification set to be transmitted to the terminal by the base station. According to the message transmitting method, the message transmitting device and the method for accessing the terminal to the PLMN, the technical problem, in the prior art, that the terminal selects the PLMN which cannot be supported by an MME connected with the base station to conduct accessing so that access failures are caused is solved, and the technical effect of improving the access success rate is achieved.
Description
Technical field
The present invention relates to the communications field, accesses in particular to a kind of method for sending information and device and terminal
The method of PLMN.
Background technology
In prior art, terminal sends a public land mobile network for itself desiring access to base station（Public
Land Moblie Network, referred to as PLMN）PLMN mark, by taking PLMN2 as an example, base station is selected from coupled MME
Select the mobile management unit of supported PLMN 2（Mobility Management Entity, referred to as MME）, so as to terminal is led to
Cross the MME and access PLMN2.However, since the PLMN supported by each MME is not fixed, and it is not necessarily configured MME
All of PLMN is supported all, therefore, it may appear that it is that the MME being connected with base station is not supported that terminal selects the PLMN for accessing, from
And access failure can be caused, reduce the success rate of access.
As shown in figure 1, illustrating the problems referred to above with a specific example.Fig. 1 is with enhanced base station（evolved
NodeB, referred to as eNB）As base station a kind of example illustrating, the base station supported PLMN 1 and 2, using PLMN1 as master
PLMN.MME1 supported PLMN 1 and 2, MME2 supported PLMN 2 and 3, MME3 supported PLMN 1 and 3.Set up in eNB and MME1
During S1, eNB carries PLMN1234, and MME does not support 34, only replys 12.When eNB and MME2 sets up S1, eNB carries PLMN1234,
MME2 does not support 14, only replys 23.When eNB and MME3 sets up S1, eNB carries PLMN1234, and MME3 does not support 24, only replys
13.In the protocol, MME must support whole PLMN of eNB and during failed call S1, therefore when there is scene as shown in Figure 1
When, MME does not support that the main PLMN of eNB, S1 can also be successfully established.At this moment PLMN1234 can be issued in broadcasting.If when now
When UE have selected PLMN4 accesses, will be refused by base station.Because there is no supported PLMN 4 in all MME being connected with base station
MME, therefore cause access failure.
For above-mentioned problem, effective solution is not yet proposed at present.
The content of the invention
The invention provides a kind of method that method for sending information and device and terminal access PLMN, existing at least to solve
There is terminal in technology to have selected the PLMN that the MME being connected with base station do not supported to be accessed and the technology of caused access failure is asked

Specific embodiment
Below with reference to accompanying drawing and in conjunction with the embodiments describing the present invention in detail.It should be noted that not conflicting
In the case of, the feature in embodiment and embodiment in the application can be mutually combined.
A kind of method for sending information is present embodiments provided, as shown in Fig. 2 the method comprises the steps：
Step S202：Base station determines first logo collection of the PLMN for allowing terminal to access；
Step S204：First logo collection is sent to terminal by base station.
In the present embodiment, base station first determines the set of the PLMN for allowing terminal to access, and the set is sent to terminal,
So as to terminal can determine which PLMN accessed according to the set, in this case, the PLMN that terminal is selected will be eventually
End allows the PLMN for accessing.Solved in prior art by the way, terminal have selected the MME being connected with base station and not support
PLMN accessed and the technical problem of caused access failure, reached to improve and be successfully accessed the technique effect of rate.
What the cell that the intersection of the PLMN supported by the MME that can be connected with base station by determination is located with terminal was supported
The set of the PLMN occured simultaneously to determine terminal permission access between the set of PLMN.In a preferred embodiment, can be with
The first logo collection is determined in the following way, as shown in figure 3, the method comprises the steps：
Step S302：Base station receives the message that one or more MME being connected with base station are issued, and wherein, carries in message
There are the PLMN marks of the PLMN of MME supports；
Step S304：The message coalescing issued from one or more MME for receiving is obtained all and base station by base station
Second logo collection of the PLMN that one or more connected MME are supported；
Step S306：The PLMN that second logo collection is supported with terminal place cell is merged by base station, will be merged
The result for arriving is used as the first logo collection.
The first logo collection for determining by the way, the set are that one or more MME being connected with base station are supported
PLMN intersection and cell support PLMN set between common factor, thereby may be ensured that the institute in first logo collection
