For example, the base station may be a base transceiver station (Base Transceiver Station, BTS for short) or a base station controller (BSC) in GSM or CDMA; or may be a Node B (Node B in UMTS). It is a radio network controller (RNC) in NB or UMTS; it may also be an evolved base station (Evolutional Node B, referred to as ENB or eNodeB) in LTE; or it may be a wireless communication network. Other access network devices that provide access services in the present invention are not limited in the present invention.

In the existing wireless network system, when load balancing is performed between systems, the access networks of different wireless access systems need to exchange the cell load information corresponding to each access network node, so that load balancing can be realized, with two different For example, the wireless access system is a first wireless access system and a second wireless access system, where the first wireless access system can be a universal mobile communication system (Universal Mobile Telecommunications System, Hereinafter referred to as: UMTS), The second radio access system may be Long Term Evolution (LTE); of course, the first radio access system is LTE, and the second radio access system is UMTS, and the implementation principle and technology thereof.

Requesting the cell load information, the secondary eNB obtains the cell load information of the base station in the UMTS system that needs the request from the primary eNB, and the communication between the secondary eNB and the primary eNB belongs to the internal signaling interaction process of the system, and does not need to go through the core. The network, thereby alleviating the signaling processing burden of the source core network entity and the target core network entity. For convenience of description, the primary base station is hereinafter referred to as a first base station, the secondary base station is referred to as a second base station, and the base station in the UMTS system is referred to as a third base station.

The technical solutions of the present invention are described in detail below in several specific embodiments.

1 is a schematic flowchart of Embodiment 1 of an information transmission method according to the present invention. As shown in FIG. 1, the method in this embodiment includes:

S101: The second base station sends the first resource status request information to the first base station.

The first resource status request information includes a cell identifier of the third base station, where the first resource status request information is used to request cell load information of the third base station, where the first base station and the second base station are in the first radio access system. The access network control node (ie, the primary eNB and the secondary eNB in the LTE system), the third base station is the access network control node of the second wireless access system, that is, the radio network controller in the UMTS system (Radio Network Controller, Abbreviation: RNC), the first wireless access system described above is different from the second wireless access system described above.

The primary eNB and the secondary eNB are further defined for the eNB according to the behavior of the two eNBs for convenience of description. The primary eNB transmits the requested load information of the third base station to the secondary eNB. The secondary eNB requests the primary eNB for load information of the third base station. After the first base station receives the first resource status request information sent by the second base station, if the first base station stores the cell load information of the third base station corresponding to the cell identifier of the third base station in the first resource status request information, If the cell load information of the third base station corresponding to the cell identifier of the third base station in the first resource state request information is not stored in the first base station, the third base station may be acquired by the steps of S102 and S103. Cell load information. It is to be noted that the cell load information of the third base station stored in the first base station may also be obtained by the steps of S102 and S103, which is an implementation manner, or the third base station actively takes its own cell. The manner in which the load information is reported to the first base station is not limited in the manner in which the first base station acquires the cell load information of the third base station.

S102: The first base station sends second resource status request information to the third base station.

The second resource status request information includes a cell identifier of the third base station, and the second resource status request information is used to request the cell load information of the third base station.

After receiving the second resource status request information, the third base station corresponding to the cell identifier of the third base station sends the second resource status report information to the first base station, where the second resource status report information includes the cell load of the third base station. information.

S103: The first base station receives the second resource status report information sent by the third base station.

The first base station uses the second resource status report information as the first resource status report information, or generates the first resource status report information by using the cell load information of the third base station included in the second resource status report information, and generates the first resource status. The status reporting information is sent to the second base station, that is, the step of S104.

S104: The first base station sends the first resource status report information to the second base station.

The first resource status report information includes cell load information of the third base station.

In this embodiment, the second base station sends the first resource status request information to the first base station, and requests the cell load information of the third base station corresponding to the cell identifier in the first resource status request information, and the first base station passes the second base station to the second base station. Sending the first resource status report information, and sending the cell load information of the third base station requested by the second base station to the second base station, so that the second base station obtains the cell load information of the third base station, when different second base stations request the same When the cell load information of the third base station is used, the first base station only needs to send the request information to the third base station to request the cell load information of the third base station, or the third base station only needs to report the cell load information of the third base station to the first base station, and then The second base station obtains the cell load information of the third base station from the first base station by transmitting the internal signaling of the system, thereby alleviating the signaling processing burden of the source core network entity and the target core network entity. In the embodiment shown in FIG. 1, in the step S101, the first resource status request information sent by the second base station to the first base station may further include a cell identifier of the first base station, where the first resource status request information is further used. The cell load information of the first base station is requested, that is, the second base station simultaneously requests the cell load information of the first base station and the cell load information of the third base station by using one request message. In the step of S104, the first resource status report information sent by the first base station to the second base station further includes cell load information of the first base station itself. Through the above technical solution, signaling resources are further saved.

Further, in the above embodiment, the first resource status request information may further include a resource status reporting period, and when the first resource status request information includes a resource status reporting period, the first base station sends the second base station to the second base station. The specific implementation manner of the resource status reporting information may be: if the first base station receives the cell load information of the third base station sent by the third base station before the resource status reporting period timer expires, the first base station receives the third When the cell load of the third base station is sent by the base station, the first resource status report information is sent to the second base station, and the resource status report period timer starts to start the next period, where the first resource status report information includes the third Cell load information of the base station and cell load information of the first base station.

If the first base station does not receive the cell load information of the third base station that is sent by the third base station before the resource status report period expires, the first base station reports to the foregoing when the resource status reports the period timer expires. The second base station sends the first resource status report information, and starts the time period of the resource status report period timer to start the next period, where the first resource status report information includes the cell load information of the first base station.

That is, when the cell load information of the third base station is received, the cell load information of the first base station and the third base station is reported to ensure that the second base station obtains an accurate load in time when the cell load information of the third base station changes. The information is used to perform more accurate load balancing. When the cell load information of the third base station is not received, the cell load information of the first base station is reported in the resource status reporting period, that is, the cell load information of the first base station is frequently reported. When the signaling resource is wasted, and the cell load information of the first base station is changed to a certain extent, the second base station can learn the cell load information after the change of the first base station after delaying a resource state reporting period.

In order to more clearly describe a technical solution in which the first resource status request information sent by the second base station to the first base station includes the cell identifier of the first base station, the cell identity of the third base station, and the resource status reporting period, the present invention is When the first resource status request information includes a cell identifier of the first base station, a cell identifier of the third base station, and a resource status reporting period, the information transmitting party of the present invention FIG. 2 is a schematic diagram of a signaling flow according to Embodiment 2 of the information transmission method of the present invention. The method in this embodiment includes:

S201: The second base station sends the first resource status request information to the first base station.

The first base station starts the resource status reporting period timer, and then executes S202.

S202: The first base station sends second resource status request information to the third base station.

The second resource status request information includes a cell identifier of the third base station, and the second resource status request information is used to request the cell load information of the third base station. Take the UMTS and LTE standards as an example, where the first base station and the second base station are eNBs, and the third base station is an RNC. The cell identifier of the first base station is an Evolved Universal Terrestrial Radio Access Network Cell Global Identifier (hereinafter referred to as ECGI), and the third base station cell identifier is a common terrestrial radio access network source cell identifier. (UTRAN Source Cell ID, hereinafter referred to as USCI).

If the first base station receives the second resource status report information sent by the third base station before the resource status reporting period timer expires, the second resource status report information includes the cell load information of the third base station.

That is, S203 occurs when the resource status reporting period timer tl is less than the resource status reporting period T.

S203: The third base station sends the second resource status report information to the first base station.

After the first base station receives the second resource status report information sent by the third base station, the first base station performs

S204: The first base station sends the first resource status report information to the second base station, where the first resource status report information includes the cell load information of the third base station and the cell load information of the first base station.

The first base station starts the timing of the resource state reporting period timer to start the next cycle.

If the first base station does not receive the second resource status report information sent by the third base station before the resource status report period expires, when the resource status reports the period timer expires, that is, the resource status report period timer timer t2 is equal to When the resource status is reported in the period T, S205 is executed.

S205: The first base station sends the first resource status report information to the second base station, where the first resource status report information includes the cell load information of the first base station.

In this embodiment, the resource state reporting period is implemented to report the cell load information of the first base station and the third base station when the cell load information of the third base station is received, to ensure that the third base station is small. When the area load information changes, the second base station obtains accurate load information in time to perform more accurate load balancing. When the cell load information of the third base station is not received, the cell of the first base station is reported to the cell according to the resource status reporting period. The load information, that is, the signaling resource waste caused by frequently reporting the cell load information of the first base station is avoided, and the second base station can delay a resource state when the current cell load information transmission of the first base station is changed to some extent. After the reporting period, the cell load information after the change of the first base station is obtained.

When the first base station requests the cell load information of the third base station by using the core network node mobility management entity (Mobility Management Entity, MME) and the serving GPRS support node (SGSG), the third base station may be instructed to indicate the third base station. The cell load information of the third base station is reported in an event-triggered manner. For example, the cell load information reported by the third base station may be triggered by the number of measurement reporting levels reported by the cell load information of the third base station. The third base station allocates the cell load scale below the overload threshold according to the specified number of measurement reporting levels, and performs an average distribution to obtain a reporting level. When the cell load changes from one reporting level to another reporting level, or when the cell load reaches the load state or leaves the overload state, the third base station needs to report the cell load to the second base station. For example, the cell overload threshold is set to 90%, the number of measurement reporting levels is 2, and the cell load scale corresponding to the reporting level is 30%, 60%, when the cell load changes from 35% to 70%, or from 40% to When 90%, or changes from 40% to 20%, the third base station needs to report the cell load to the second base station.

However, when the second base station obtains the cell load information of the third base station by using the first base station, if the number of measurement reporting levels reported by the third base station cell load information requested by the multiple second base stations is different, The first base station needs to negotiate with the second base station to determine the number of measurement reporting levels, so that the third base station reports its own cell load information to the first base station according to the determined number of measurement reporting levels.

The technical solutions for determining the number of measurement reporting levels by the first base station and the second base station according to the present invention are described in detail below in several specific embodiments.

FIG. 3 is a schematic flowchart of Embodiment 3 of the information transmission method of the present invention. As shown in FIG. 3, the method in this embodiment includes:

S301: The second base station sends the first resource status request information to the first base station.

The first resource status request information includes a cell identifier of the third base station, where the first resource status request information is used to request cell load information of the third base station, where the first base station is And the second base station is an access network control node of the first radio access system, the third base station is an access network control node of the second radio access system, the first radio access system and the second radio connection Different types of entry.

S302: The first base station sends the first resource status response information to the second base station.

S303: The second base station learns, according to the first resource status response information, whether the first base station receives the request of the second base station for the cell load information of the third base station.

Specifically, in this embodiment, one of the implementation manners: the first resource status request information sent by the second base station to the first base station may further include the number of measurement reporting levels reported by the third base station cell load information.

If the first base station supports the number of measurement reporting levels reported by the third base station cell load information, the first resource response information sent by the first base station to the second base station includes the receiving indication information, and the second base station learns the first information according to the receiving indication information. The base station receives the cell load information of the third base station by using the number of measurement reporting levels reported by the third base station cell load information, that is, the third base station sends the first resource status request information sent by the second base station to the first base station. The number of measurement reporting levels reported by the third base station cell load information is reported to the cell load information of the third base station.

If the first base station does not support the number of measurement reporting levels reported by the third base station cell load information, the method may be divided into two cases. The first case: the first resource response information sent by the first base station to the second base station includes the reject indication information. The second base station learns, according to the foregoing refusal indication information, that the first base station refuses to request the third base station cell load information, that is, the current first base station does not support the third base station, and the third base station sends the third base station cell load information to report the number of measurement reporting levels. And terminating the request process of the second base station for the cell load information of the third base station. The second case: the first resource status response information sent by the first base station to the second base station includes the number of measurement reporting levels reported by the third base station cell load information supported by the first base station, and uses the third base station supported by the first base station. The number of measurement reporting levels reported by the cell load information is used to request the cell load information from the third base station, and the second base station learns that the first base station acquires the third reporting base station by using the number of measurement reporting levels reported by the third base station cell load information supported by the first base station. Cell load information.

In another implementation manner, the first resource status request information sent by the second base station to the first base station may not include the number of measurement reporting levels reported by the third base station cell load information, but the first base station sends the second base station to the second base station. The first resource status response information includes the number of measurement reporting levels reported by the third base station cell load information supported by the first base station, and the second base station learns that the first base station will The cell load information of the third base station is obtained by using the number of measurement reporting levels reported by the third base station cell load information supported by the first base station.

With the technical solution of the foregoing embodiment, the first base station and the second base station determine, by using a negotiation manner, the number of measurement reporting levels reported by the third base station cell load information, and solve the number of measurement reporting levels requested by different second base stations. At the same time, the technical problem of the cell load information of the third base station cannot be obtained.

In order to reduce the signaling processing burden of the core network, the present invention also provides an embodiment of an information transmission method. As shown in FIG. 4, FIG. 4 is a schematic flowchart of Embodiment 4 of the information transmission method according to the present invention; S401: The fourth base station The third base station sends a neighbor relationship of the fourth base station.

The fourth base station refers to the access network node of the first radio access system, and the third base station refers to the access network node of the second radio access system. In this embodiment, the first radio access system is LTE, The second wireless access system is UMTS as an example. The neighbor relationship of the fourth base station is used to indicate the neighbor base station of the fourth base station.

The neighboring cell relationship of the fourth base station that is sent by the fourth base station to the third base station may be in the following two forms. The first type: the fourth base station reports the cell identity ECGI of the neighboring cell of the fourth base station to the third base station; The fourth base station reports the global identity of the eNB with which the X2 interface is established to the third base station, where the X2 interface is an interface between the base station and the base station, and specifically refers to the interface between the eNB and the eNB. The X2 interface is established between the base station and the base station through mutual signaling. When an X2 interface exists between two base stations, the base station and the base station can exchange information of each other through the X2 interface.

For example, one base station can notify another base station, its own cell, the neighboring cell of its own cell, the load information of its own cell, and the like.

Here, the cell identifier ECGI of the neighboring cell reported by the fourth base station, where the ECGI includes the identifier of the Public Land Mobile Network (PLMN) and the evolved universal terrestrial radio access network cell identifier. The evolved universal terrestrial radio access network cell identifier includes an evolved base station identifier. According to the PLMN and the evolved base station identifier, the global evolved base station identifier (Global eNB ID) can be known. That is, the Global eNB identity consists of a PLMN identity and an evolved base station identity.

In the second mode, the fourth base station sends, to the third base station, a global identifier of the eNB that can communicate with the X2 interface, that is, the Global eNB ID and the global evolved base station identifier.

It should be noted that, since the Global eNB ID includes the PLMN identity, when the fourth base station When the PLMN identifiers of the neighboring cell base stations (eNBs) are the same, in order to save bits, only one PLMN identity and the evolved base station identity of the eNBs may be transmitted in the neighbor relationship. Certainly, if the PLMN identifiers of the neighboring base stations are the same as the PLMNs in the Global eNB ID of the fourth base station, the neighboring cell relationship may not include the PLMN identity information, and only the evolved base station identifier of the neighboring cell eNB.

S402: The third base station manages the neighbor relationship according to the neighbor relationship sent by the fourth base station. It is to be noted that the neighboring cell relationship of the fourth base station is obtained by reporting the neighboring cell relationship by the fourth base station, which is only one implementation manner of the third base station acquiring the neighboring cell relationship, and the third base station may also obtain the fourth base station by other methods. The neighbor relationship is obtained, for example, by the network management system of the LTE system, and the present invention is not limited thereto.

For convenience of description, in the following, the neighboring base station of the fourth base station is referred to as a fifth base station.

S403: The third base station receives the third resource status request information sent by the fourth base station.

The third resource status request information is used to request the cell load information of the third base station, where the third resource status request information includes the third base station cell identifier and the third measurement reporting level number.

S404: The third base station sends the third resource status report information to the fourth base station.

The third resource status report information includes cell load information of the third base station.

The third resource status reporting request information includes the third measurement reporting level number, that is, the third base station reports the cell load information of the third base station to the fourth base station according to the event triggering manner.

When the cell load information of the third base station is reported to the fourth base station according to the event-triggered method, the method is performed as follows.

S405: The third base station determines, according to the neighbor relationship, whether the fourth resource status request information sent by the fifth base station in the neighbor relationship of the fourth base station is further received. If yes, execute S406, if no, execute S410.

The fourth resource status request information includes a cell identifier of the third base station and a fourth measurement reporting level number.

It should be noted that the third base station cell identifier in the third resource status request information and the third base station cell identifier in the fourth resource status request information in the implementation refer to the same cell identifier, that is, the ECGI is the same.

S406: The third base station determines whether the number of the third measurement reporting levels is the same as the number of the fourth measurement reporting levels. If they are the same, S407 is executed, and if not, S410 is executed.

If they are the same, the fourth base station and the fifth base station request the third base station to use the same event triggering strip. The device reports the cell load information of the third base station to it.

S407: The third base station sends the fourth resource status report information to the fourth base station.

The fourth resource status reporting information includes the cell load information of the third base station and the global evolved base station identifier of the fifth base station, and the global evolved base station identifier of the fifth base station, that is, the Global eNB ID. After receiving the fourth resource status report information, the fourth base station acquires the cell load information of the third base station, and sends the global evolved base station identifier in the fourth resource status report information to the base station corresponding to the global evolved base station identifier by using the X2 interface. Load information of the third cell.

It should be noted that, since the Global eNB ID includes the PLMN identifier, when the PLMN identifiers in the Global eNB IDs of the multiple fifth base stations are the same, in order to save bits, only one PLMN identifier and the plurality of fifth base stations may be sent. Evolved base station identity. Of course, if the PLMN identifier in the Global eNB ID of the one or more base stations is the same as the PLMN identifier in the Global eNB ID of the fourth base station that receives the fourth resource status report information, the evolution may be sent only. The type of base station identity does not need to send the PLMN corresponding to each fifth base station. The fourth base station that receives the fourth resource status report information can infer each fifth base station global evolved base station identifier that needs to receive the third base station cell load according to the foregoing rule, and send the cell load of the third base station to these The fifth base station.

S408: The fourth base station that receives the fourth resource status report information sends the cell load information of the third base station to the fifth base station corresponding to the global evolved base station identifier in the fourth resource status report information.

And the fourth base station that receives the fourth resource status report information sends the cell load information of the third base station to the fifth base station corresponding to the global evolved base station identifier in the fourth resource state report information, and also sets the “target cell identifier” and The "source cell identifier" is sent to the fifth base station, where the "source cell identifier" includes the identifier of the third base station and the marking area identification (RAI) of the third base station; "target cell identifier", The global evolved base station identifier of the fifth base station and the tracking area identifier (TAI) of the fifth base station.

S409: After receiving the third cell load information, the fifth base station determines whether to store the cell load information of the third base station according to the “target cell identifier” and the “source cell identifier” carried therein.

If the "target cell identifier" is its own identification information, the "source cell identifier" is the identification information of the requested third base station, and the cell load of the third base station is the cell load requested by itself, then the storage is performed. The cell load information of the third base station, otherwise, it is discarded.

S410: The third base station sends the cell load information of the third base station to the fourth base station that sends the third resource status request information according to the third measurement reporting level number.

In this embodiment, the third base station manages the neighbor relationship of the fourth base station in the first radio access system, and the fourth base station and the fifth base station having the neighbor relationship with the fourth base station receive the same event trigger condition ( When the same cell load information of the third base station is requested, the third base station sends the fourth resource state report information to the fourth base station according to the neighbor relationship, and the fourth resource state report information includes the cell load information of the third base station. And the global evolved base station identifier of the fifth base station, the fourth base station that receives the fourth resource status report information sends the cell load information of the third base station, and the “target cell identifier” and the fifth base station corresponding to the global evolved base station identifier. The source cell identifier "", thereby effectively reducing the signaling processing load of the core network.

It is to be noted that, in the above embodiment, the third base station sends the fourth resource status report information to the fourth base station in S407. Alternatively, the third base station may also select to send the fourth resource status report information to one of the fifth base stations that send the fourth resource status report information, and accordingly, the fourth resource status report information includes the cell load information of the third base station. And a global evolved base station identifier of the fifth base station that reports the fourth resource status reporting information. The fifth base station that receives the fourth resource status report information acquires the cell load information of the third base station, and uses the X2 interface to the fourth base station according to the fourth base station and the other fifth base station in the fourth resource status report information. The base station and the other fifth base station transmit the cell load information of the third base station. Means, when the base station with the neighbor relationship requests the cell load information of the same third base station (the different system base station) by the same event trigger condition (the number of measurement reporting levels), the third base station can only send resources to any one of the base stations. The status report information, the resource status report information includes the cell load information of the third base station and the global evolved base station identifier of the other requesting base station, and the base station that receives the resource status report information reports the global evolved base station in the resource status report information through the X2 interface. The corresponding base station is configured to send the cell load information of the third base station that is obtained by the corresponding base station, and the implementation principle and technical effects thereof are similar to the embodiment shown in FIG. 4, and details are not described herein again.
