S1 chain of command connects normal but S1 user face connects limited.Wherein, connection limited referring in S1 user face can pass
Defeated user face data limited, that do not ensure service quality.
Base station self is understood in real time or periodic monitoring S1 connection status, connects disconnection when monitoring S1, confirms as
S1 connects fault；The type that base station herein is suitable for is eNB；
If it is limited to occur S1 to connect, then operation management maintainance (Operation Administration and
Maintenance, OAM) entity can send to base station and connect limited notice about S1, works as base station monitors
To this notice, confirm as S1 and connect fault.The type that base station herein is suitable for is eNB and NeNB.
S1 connects limited reason and is probably: the S1 that Nomadic disposes temporarily connects, or when there is disaster
Replacement S1 connect.
When above-mentioned base station monitors is to S1 connection fault, it may be judged whether there is below adjacent I OPS system existence
Mode:
Mode one, base station judge to monitor before S1 connects fault whether received built IOPS system
Neighbor base station send notification message, if the determination result is YES, then it is determined that adjacent I OPS system；
Otherwise, then it is judged to not exist.
After mode two, base station monitors connect fault to S1, send request message, request to all neighbor base stations
Inform whether described neighbor base station has built IOPS system；
Base station receives the response message that described neighbor base station returns；
Base station judges whether to there are in described response message the instruction of built IOPS system, if judged result
It is designated as built IOPS system at least one, then it is determined that adjacent I OPS system；If judging
Result does not has built IOPS system for being all designated as, then be judged to there is not adjacent I OPS system.
It addition, when base station is NeNB, there is also a kind of situation, it may be assumed that after NeNB initializes, it is judged that
Whether there is adjacent I OPS system, this judgement uses aforesaid way two.
Step 102, if there is adjacent I OPS system, then base station adds described adjacent I OPS system.
For mode one, when there is adjacent I OPS system, base station also needs to judge whether only to receive one
Described notification message, if the determination result is YES, then it is determined that an adjacent I OPS system, and adds
Corresponding adjacent I OPS system.
For mode two, when there is adjacent I OPS system, base station also needs to judge to deposit in described response message
At one or the most a plurality of be designated as built IOPS system, if judged result has been designated as only existing one
Built IOPS system, or, it is judged that result is to have in all response messages a plurality of to be designated as built IOPS
System and be all designated as same IOPS system, then it is determined that an adjacent I OPS system, and add
Enter the adjacent I OPS system of correspondence；If judged result a plurality of has been designated as built IOPS system for existing, and
When indicating multiple different IOPS system, then it is determined that multiple adjacent I OPS system, by corresponding
Multiple adjacent I OPS systems merge, and add the adjacent I OPS system after merging, or select to add
One of them adjacent I OPS system.
Above-mentioned addition adjacent I OPS system, including: set up local S1 and connect, the adjacent I OPS that broadcast is added
Cell ID that system is proprietary and/or public land mobile network (Public Land Mobile Network,
PLMN) mark and/or tracing area mark (Tracking Area Identity, TAI).
Merge IOPS system to refer to: configure multiple IOPS system and use identical cell ID and/or PLMN
Mark and/or TAI.
It is pointed out that in mode one, there is also a kind of result, it may be assumed that base station is monitoring S1 connection event
Receiving a plurality of described notification message before barrier, this plurality of notification message indicates different adjacent I OPS system
System, in such cases, any process is not made in the base station receiving notification message, by sending described notification message
Neighbor base station multiple different adjacent I OPS systems are merged.
Step 103, if there is not adjacent I OPS system, then the newly-built IOPS in base station system.
For determining the scene that there is not adjacent I OPS system in mode one, base station does not processes.
For determining the scene that there is not adjacent I OPS system in mode two, base station needs newly-built IOPS system.
Newly-built IOPS system refers to: sets up local S1 and connects；Then, newly-built IOPS system is sent special
Some synchronizing signals, or, send the system broadcast message that newly-built IOPS system is proprietary.Herein, eNB
Automatic newly-built IOPS system, NeNB is controlled newly-built IOPS system by operator.
After base station adds adjacent I OPS system or newly-built IOPS system, described base station notice is (neighbouring or new
Build) UE in IOPS system coverage area notify the following information of user by UE: it is operated in IOPS
Communication pattern and/or whether support that limited S1 connects and/or only supports limited local service.
