Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
For dual link, due to the otherness of master base station (MeNB) and prothetic group station (SeNB), if network side can basis
Random access reports (RACH-report) to distinguish main and auxiliary base station, then facilitates network positions random access (RACH) problem.
For CA, similarly, if network can distinguish which carrier wave RACH is on, it helps network positions problem.
Please refer to Fig. 1, the acquisition methods of the terminal connection status under a kind of multi-connection scene provided in an embodiment of the present invention,
Applied between network side and terminal, the terminal and the foundation of multiple base stations have connection, method includes the following steps:
Step 11, the lateral terminal of network sends request message, and the request message is used to request connecing at random for default base station
Enter state, the default base station is the base specified in network side and the base station either request message that terminal has been made an appointment
It stands.
Here, above-mentioned request message can specifically pass through wireless heterogeneous networks (RRC) signaling message (such as UE information request
Signaling) it is sent to terminal, requesting terminal reports the report of random access in the signaling.
Step 12, network side receives terminal and is directed to the response message that the request message returns, and takes in the response message
Random access report with the default base station.
From above step as can be seen that network and terminal appoint default base station, Huo Zheyou in advance in the embodiment of the present invention
Network side directly indicates the default base station in request message, so that terminal reports the random access report of the default base station.
In this way, network side after receiving the response message, can determine that is wherein carried is the random access report of which base station,
And then it can be reported according to the random access and go positioning relevant issues.
As an implementation, above-mentioned default base station can be the base station that network side is specified by the request message,
Specifically, the default base station is the master base station of terminal connection or is prothetic group station or be the terminal that the terminal connects
The master base station of connection and prothetic group station.Network side carries the instruction information for being used to indicate the default base station in request message, in this way,
After terminal receives the request message, parsing obtains instruction information, determines the default base station, and then in the response message
The random access report of the middle feedback default base station.
Under carrier aggregation scene, terminal may be established on multiple carrier waves (such as main carrier, subcarrier) with respective base station
Connection.To obtain the corresponding carrier information of random access, in the embodiment of the present invention, the request message is further used for request and exists
Random access state on the default carrier wave of the default base station, similar, the default carrier wave can be network side and terminal
The carrier wave specified in the carrier wave the made an appointment either request message.In this way, terminal is further in the response message
Random access report of the terminal on the default carrier wave of the default base station is carried, so that network side is obtained with terminal
Random access report on the specific carrier wave of specific base station, is more advantageous to orientation problem.
For example, the default base station can be when the default carrier wave is the carrier wave specified by the request message
The terminal connection master base station or be the terminal connection prothetic group station or be the terminal connection master base station and prothetic group station,
The default carrier wave refers to main carrier subcarrier or main carrier and subcarrier.It can refer in the request message
Show the random access report on the carrier wave for reporting which frequency point, which cell or which standard.Here, terminal receives net
After the request message of network, RRC signaling message (such as UE information-reply) is sent to network side, in the message according to specific instruction content
It is middle to carry corresponding random access report.
Specifically, in addition to existing random access lead code (preamble) transmission time in the random access report reported
Number, if detect outside the parameters such as competition (contention), mark (such as PCI, cell of respective cell can also be reported
Identity), location information, whether reach maximum transmission power, the parameters such as time be already expired away from random access failure.Wherein, it is
The no maximum transmission power and the two parameters of time apart from random access failure of reaching can be only for random access failure
Report.In the embodiment of the present invention, cell ID that network side can report in message according to response distinguishes major-minor base station, master
Secondary cell.In addition to this it is possible to which the IE that respectively major-minor base station, major-minor cell definitions are different, terminal are taken in the response message
Band presets base station and the corresponding IE of default carrier wave, and the IE that network side carries in message according to response determines that the random access is reported
For base station/carrier wave.Specifically, network side indicates default base station and default carrier wave, network side and terminal in request message
Side can be realized according to following methods, be illustrated below:
Situation a: for network side, instruction terminal only reports the random access feelings at master base station or prothetic group station in request message
Condition, terminal report the random access report of master base station or the successful random access (not distinguishing main and auxiliary carrier wave) of prothetic group station last time
Accuse (whether such as lead code number of transmission detects competition information).Network side can also indicate on only in request message
Report the random access situation of main plot or secondary cell, or both, then terminal report on master base station (or prothetic group station) main carrier or
Subcarrier, or both on the last time successfully random access random access report.It is of course also possible to be recently repeatedly at
The random access report of fruit access.
Situation b: if network side indicates in request message while reporting the random access situation at master base station and prothetic group station,
Terminal reports the random access of the last successfully random access (not distinguishing main and auxiliary carrier wave) on master base station and prothetic group station simultaneously
Report.If network further indicates main plot or secondary cell in request message, or both random access situation, then
Terminal report simultaneously main carrier on master base station and prothetic group station or subcarrier, or both on the successful random access of last time
Random access report.
Situation c: if network side indicates to report the random access situation of failure in request message, terminal reports nearest one
(whether lead code number including transmission detects competition, cell ID, position to the corresponding information of secondary or multiple random access failure
Whether confidence breath reaches maximum transmission power, the time is already expired away from random access failure, serving cell/measurement information in neighbor cell
Deng).Random access failure can be only for the random access failure on subcarrier or prothetic group station.In order to be reported, terminal is needed
Relative recording is carried out when random access failure occurs.After the completion of reporting, terminal deletion random access report record.In addition,
Other than network is explicitly indicated and reports the random access situation of failure, terminal can be defaulted in the report of network request random access
Report the random access information of failure.
As another embodiment, above-mentioned default base station can be network side and that terminal side is appointed in advance is (i.e. silent
Recognize base station), specific base station need not be thus indicated in request message.After terminal receives above-mentioned request message, that is, send
The random access of the default base station is reported.Further, the default carrier wave is also possible to network side and terminal side in advance about
(i.e. the default carrier wave) set, need not thus indicate specific carrier wave in request message.Terminal receives above-mentioned request and disappears
After breath, that is, send the random access report on the default carrier wave of the default base station.
For example, default base station and default carrier wave can have following several situations, and optional one is implemented, it is only necessary to network
Side and terminal are reached an agreement with regard to default base station in advance:
Situation i: terminal only reports the last successfully random access (not distinguishing main and auxiliary carrier wave) on master base station.Specifically
Ground, terminal judged according to the time of random access on main carrier and secondary carrier the random access on which carrier wave be it is nearest,
Then the random access situation on the carrier wave is reported.If the random access on main carrier and subcarrier is simultaneously, by end
End determines that the random access on which carrier wave is selected to go to report.
Situation ii: terminal only reports on master base station the last successful random access on main carrier.
Situation iii: terminal reports the last successful random access on master base station main carrier and subcarrier simultaneously.
Situation iv: terminal only reports the last successfully random access on master base station and prothetic group station (not distinguish main and auxiliary load
Wave).Specifically, to the main and auxiliary carrier wave on a base station, terminal is sentenced according to the time of random access on main carrier and secondary carrier
The random access on which carrier wave that breaks be it is nearest, then report the random access situation on the carrier wave.If main carrier and pair
Random access on carrier wave be while, terminal determine select which carrier wave on random access go to report.
Situation v: terminal only reports the last successful random access on each autonomous carrier wave of master base station and prothetic group station.
Situation vi: terminal reports the last successful random access on master base station main carrier and subcarrier simultaneously, and
The successful random access of last time on prothetic group station owner carrier wave and subcarrier.
Situation vii: terminal selects nearest random access report to be reported in master base station and prothetic group station.Specifically,
Terminal judged according to the time of random access on master base station and prothetic group station the random access on which base station be it is nearest, then
Report the random access situation on the base station.If the random access on two base stations be while, terminal oneself determine selection
Random access on which base station goes to report；Here, the needs that give the correct time in terminal indicate the corresponding base of report at random currently reported
It stands.
It is exemplified above based on the random access report reporting arranged in advance.The embodiment of the present invention is connect at random reporting
Enter report (can be and report based on what is arranged in advance, be also possible to indicate specifically default base station and carrier wave in request message)
When, the nearest M times random access report being successfully accessed can be reported；It is also possible to report the random access of nearest n times failure
Random access report；It can also be aforementioned either way to be reported, that is, report the random of nearest M times successful random access
Access report, and n times failure recently random access random access report, here, M and N are the integer more than or equal to 1.
Other than random access report, network side it may also be desirable to understand master base station/prothetic group station and terminal room radio chains

It can use., can be by dedicated signaling to the terminal request problem report after network receives, then terminal again will be in the problem report
Offer network.If radio link problem occurs for multiple serving cells on prothetic group station, multiple cells can be reported.If net
Network does not request the problem report, then terminal removes the radio chains of record when deleting respective cell, prothetic group station or Connection Release
Road problem.Here, terminal can be recorded based on the requirement of network side and radio link problem is reported to report.Specifically, network
Side can first pass through whether dedicated signaling configurating terminal needs to report the problem when radio link problem occurs: if being configured to need
It wants, then the radio link problem that terminal record occurs simultaneously is reported, to carry out reporting for radio link problem.
It is directed to the radio link problem of master base station, terminal first records the radio link problem report of master base station, wherein right
The Radio Link Failure caused by random access, terminal record random access failure relevant information (the lead code number such as sent,
Whether competition, cell ID, location information are detected, if reach maximum transmission power, the time is already expired away from random access failure, take
Business cell/measurement information in neighbor cell etc.).After terminal next time accesses network, when network is to the previous access of the terminal request terminal
When network when Radio Link Failure (RLF) report of master base station, then terminal can report RLF report by sending RRC information.
Here, if it is RLF caused by random access, then random access failure relevant information is added in RLF report wherein.
It is the radio link problem report for how reporting master base station, prothetic group station that terminal in the embodiment of the present invention, which is explained above,
It accuses.By above step, the embodiment of the present invention may be implemented to send the nothing of corresponding base station when radio link problem occurs for base station
