The foregoing and other features of the invention will be apparent from the The specific embodiments of the present invention are disclosed in the specification and the drawings, which are illustrated in the embodiments of the invention The invention includes all modifications, variations and equivalents falling within the scope of the appended claims. Various embodiments of the present invention will be described below with reference to the accompanying drawings. These embodiments are merely exemplary and are not limiting of the invention.

In order to minimize interference with the operator's commercial network and reduce the cost of use, the wireless connection between the small cell and the user equipment deployed by the user may no longer use the carrier-specific frequency, but use the free public frequency band, such as ISM (Industrial Scientific Medical). , Industrial Science and Medical) Frequency bands. In addition, the backhaul capability of small cells deployed by users may be uneven, and the best backhaul capability is far from the worst backhaul capability. Therefore, different small cells deployed by different users may have poor interaction with each other, which is reflected in the limited amount of interactive information and the large delay of single interaction information. On the other hand, in the dense small cell scenario deployed by the operator, the user equipment has the right to access any small cell. In a small cell deployed by a user, the number of small cells to which a user equipment has rights to access is very limited, for example, only one or two. That is to say, the small cells deployed by the user are dedicated to certain user devices, and there are few opportunities to open them to all user devices. In addition, small cells deployed by users usually have macro station coverage. Therefore, how to establish a connection between the macro station auxiliary user equipment and the small station to which it has access is a research direction of the embodiment of the present invention.

In order to solve the above problem, the embodiment of the present invention provides a solution, which enables the macro station to quickly confirm that the connected small station and the user equipment can be established, thereby assisting the small station to establish a connection with the user equipment.

The connection establishing method, device and communication system of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

The embodiment of the present invention provides a connection establishment method, and FIG. 1 is a flowchart of the method. Referring to FIG. 1, the method includes:

Step 101: The small station sends the user list of the small station to the macro station, so that the macro station assists the user equipment related to the small station to access the small station according to the user list of the small station. In this embodiment, after the small station is powered on, it will register with the macro station that covers it. During the registration process or after registration, the small station can report the user equipment list of the small station to the macro station (referred to as the user list for short). ),. The user equipment list here includes user equipments that may be served by the small station, such as user equipments that are often served by the small station. In the list, the user equipment may be characterized by the identifier of the user equipment, or may be Characterization of the manner of the embodiments. The small station can determine the user list according to the situation of the user being served by it, for example, according to the usage times or usage time of the user equipment. The station can also periodically update the list of users, such as adding some new users or deleting user devices that have not been serviced for a period of time from the user list. This list of users can be automatically updated by the station or manually by the deployer of the station.

In this embodiment, the small station may register with the macro station by sending a registration request/request (request/indication) to the macro station, and when the registration is passed, the macro station returns a registration permission/confirmation (permission I) to the small station. Confirmation) , thus completing the registration of the station to the macro station. For a specific registration process, reference may be made to the prior art, and details are not described herein again.

In this embodiment, after receiving the user list of the small station, the macro station queries, according to the user list, whether the user equipment belonging to the user list of the small station exists in the user equipment served by the macro station.

If there is a user equipment belonging to the user list of the small station in the user equipment served by the macro station, the macro station sends relevant information of the user equipment to the small station. For example, user equipment identification; and/or SIM card identification and/or USIM card identification of the user equipment; and/or location information of the user equipment; and/or uplink signal characteristics of the user equipment; and/or services related to the user equipment Feature information; and/or recommended bandwidth, etc. The uplink signal feature of the user equipment is, for example, a PRACH (Physical Random Access Channel) or a SRS (Sounding Reference Signal) signal time-frequency position and sequence transmitted by the user equipment.

Then, if the small station of the embodiment receives the information of the user equipment related to the small station sent by the macro station, the small station may perform initialization processing according to the received information, for example, selecting a working frequency point, determining Working bandwidth, etc.

Wherein, if the received information includes the location information of the user equipment, when the small station selects the working frequency point, the small station may only optimize the lobe direction mainly used to cover the user equipment from the small station. If the location information of the user equipment is not included in the received information, the small station may locate the location of the user equipment according to other information received, and then according to the location of the user equipment that is located, and then mainly used for starting from the small station. The working frequency is selected by covering the lobe direction of the user equipment. If the received message contains the above The user equipment related service characteristic information or the recommended bandwidth, the small station can determine its working bandwidth according to this. The working frequency selected by the small station is not limited to one. If it is a multi-carrier system, it may also select another one or more working frequency points.

If the user equipment belonging to the user list of the small station does not exist in the user equipment served by the macro station, the macro station may inform the small station that no user equipment is served by the macro station, and may also do nothing, and may also recommend the The bandwidth informs the station so that the station can determine its working bandwidth accordingly.

Then, at this time, if the small station does not receive the information of the user equipment related to the small station transmitted by the macro station within a predetermined time (referred to as the first predetermined time in this embodiment), or the small station receives the information If the macro station sends the indication information of the relevant user equipment, the small station can perform initialization processing according to the preset information. For the pre-set information, refer to the prior art, and details are not described herein again. In addition, if the small station receives the information of the recommended bandwidth sent by the macro station, the small station may perform initialization processing according to the preset information and the information of the recommended bandwidth, for example, selecting a working frequency point, determining a working bandwidth, and the like.

Wherein, since there is no location information of the user equipment, the small station can select the working frequency point for all directions.

In this embodiment, compared with the working frequency points that are preferably obtained for all directions, the working frequency points that are mainly used to cover the lobe direction of the user equipment from the small station can better serve the user equipment. Because the user equipment in the indoor scene is usually in a static or very slow moving state, the small station uses the lobes of the direction with a high probability during the actual service delivery.

In this embodiment, when the station selects the working frequency point, it reports the working frequency point to the macro station, for example, the selected working frequency point is notified to the macro station, so that the macro station can The station is added to its list of activities. Among them, if a small station changes its working frequency (operating frequency), the small station can notify the macro station. On the contrary, the macro station can also configure the small station to change the working frequency as needed.

In this embodiment, the macro station may maintain a list of registered stations (referred to as a registration list for short) and an active status station list (abbreviated as an activity list), and in the registration list, all the coverages under the macro station are included. The open station (characterized by the small station identification) and the user list of each station, optionally, may also include the cell ID of the station. In its activity list, it contains all the active stations covered by the macro station and the working frequency of each active station. The two lists will be described in detail in the following embodiments.

In this embodiment, the small station registered at the macro station can have two states, one is active. State, one is the dormant state. The active state means that, regardless of whether the small station is currently serving any user equipment, the small station will still send out signals periodically to help the user equipment discover and measure the small station. An active station will occupy one or more radio frequencies to maintain communication between the station and the user equipment. The sleep state means that when the small station does not serve any user equipment, the small station stops sending signals to the outside. A small station that is in a dormant state can monitor the uplink signal of some user equipments, or it can not listen at all. A small station in a dormant state can maintain communication with the macro station, but may have released the radio frequency band occupied by communication with the user equipment.

In this embodiment, after the station selects the working frequency point, a common signal can be sent at the selected working frequency point, so that the user equipment associated with the small station detects and attempts to access the small station. The common signal includes, but is not limited to, any one or any combination of the following signals: a discovery signal; system information; a common search space. Thereafter, the user equipment can detect and attempt to access the station.

Therefore, the macro station can quickly confirm the small station and the user equipment that can establish the connection, not only optimize the frequency selection of the small station when the small station is powered on, but also better prepare for the subsequent small station to provide services for the user equipment. .

In an embodiment of the embodiment, the small station may also decide whether to enter the sleep state as needed, for example, if the small station does not receive within a predetermined time (referred to as a second predetermined time in this embodiment) Regarding any information about the access of the user equipment, that is, not serving any user equipment, the small station can enter a sleep state and inform the macro station that it enters a sleep state, so that the macro station moves the station from its activity list. except.

The sleep timer can be set inside the small station. During the time period of the timer, if a new user equipment enters the coverage of the small station and becomes the served user equipment of the small station, the timer stops counting. And clearing; if no user equipment enters the coverage of the small station and becomes the served user equipment of the small station within the timeout period of the timer, the small station is released after the timer expires. The current working frequency, and stop sending signals out to enter the sleep state. Among them, the small station can enter the sleep state at its own discretion, or can request the macro station to allow, and enter the sleep state after obtaining the permission of the macro station. After the station is in hibernation, the macro station removes the station from the activity list. The small station that enters the sleep state will still keep in touch with the macro station regularly, as described above, and will not be described here.

As a result, the small station does not occupy the frequency band when there is no service object, which saves spectrum resources and reduces interference to other small stations. In addition, stopping the outgoing signal can also save energy on the small station side.

In an embodiment of the present embodiment, when the small station is in the sleep state, it is possible to receive the indication information sent by the macro station indicating that the small station changes from the sleep state to the active state, for example, when a new user equipment arrives at the macro. station, The macro station may assist the user equipment to establish a connection with the small station, and after receiving the indication information, the small station may transition from the sleep state to the active state.

Therefore, since the small station is in a dormant state and is still in contact with the macro station, even with the assistance of the macro station, even if the small station is in a dormant state, the small station can quickly change the state when necessary, so that the small station And the user device can quickly find each other.

In an embodiment of the embodiment, the small station cancels itself to the macro station that covers it before shutting down, for example, the small station sends a logout information to the macro station before shutting down, for example, sending a logout request (request)/indication ( Indication), whereby the macro station can remove the station from its registration list based on the logout information. If the station is also included in the activity list, the macro station will also remove the station from the activity list.

Among them, if the station suddenly loses power or loses connection, the macro station can decide whether to cancel the station according to its own counter or timer. The details will be described in detail in the following examples.

In one embodiment of this embodiment, a hard reset switch can be placed on the station. Once the switch is triggered, the station automatically re-starts the boot process.

Through the method of the embodiment of the present invention, the macro station can quickly confirm the small station and the user equipment that can establish the connection, so that the small station and the user equipment can quickly find each other.
