The technical solution of the present invention can be applied to various communication systems, such as: GSM (Global System of Mobile communication), CDMA (Code Division) Multiple Access, Code Division Multiple Access (CDMA) system, WCDMA (Wideband Code Division Multiple Access Wireless), UMTS (Universal Mobile Telecommunications System), GPRS (General Packet Radio Service) ), LTE (Long Term Evolution, etc.).

The UE, which may also be referred to as a mobile terminal, a mobile user equipment, etc., may communicate with one or more core networks via a radio access network (eg, RAN, Radio Access Network) through an air interface, and the user equipment may be Mobile terminals, such as mobile phones (or "cellular" phones) and computers with mobile terminals, for example, portable, pocket-sized, handheld, computer-integrated or in-vehicle mobile devices that exchange with a wireless access network Language and / or data.

The base station, which is a network element of the foregoing radio access network, may be a BTS (Base Transceiver Station) in GSM or CDMA, a base station (NodeB) in WCDMA, or an evolved base station in LTE. (eNB or e-NodeB, evolved Node B), etc., the invention is not limited.

1 is a schematic diagram of a mobile network system applicable to an embodiment of the present invention. The schematic diagram of the mobile network system of Figure 1 includes an access network and a core network, wherein the access network includes a base station and a controller.

It should be understood that in the embodiment of the present invention, although three base stations are described in FIG. 1, namely, the base station 101, the base station 102, and the base station 103; one controller 104 and the core network 105, but for convenience of description. The number of the network devices in FIG. 1 may be one or more, which is not limited by the embodiment of the present invention.

In the prior art, in order to alleviate the pressure of the downlink data traffic on the transmission network, the content storage node is deployed to each base station. For example, in the scenario diagram of FIG. 1, the base station 101, the base station 102, or the base station 103 can store the mobile Internet content. In this way, the UE can obtain the mobile Internet content in the vicinity, and can save the backhaul from the base station to the core network, and the core network to the Internet, and shorten the waiting delay time of the terminal.

However, the content storage capacity of a single base station is limited and the maintenance cost is relatively large. A large number of storage units cannot be deployed in each base station. For example, in the scenario block diagram of FIG. 1, the base station 101 has a smaller storage capacity, and the UE under the base station 101 The probability that the Internet content requesting access is stored in the base station 101 is small, and the Internet content requesting access is diverse, which results in a low hit rate of content storage for a single base station, and therefore, the base station still needs to pass through the controller and the core network. Obtaining the Internet content requested by the UE to the UE in the Internet network cannot effectively save the backhaul from the base station to the core network and the core network to the Internet, and shorten the waiting delay time of the terminal. In order to solve the above problem, an embodiment of the present invention provides an Internet content storage method and device, which enable multiple base stations to share their stored Internet content, which can increase the access hit rate of Internet content stored by the base station, and improve storage utilization. Thereby effectively saving transmission overhead and reducing delay time.

2 is a flow chart of a method for storing Internet content according to an embodiment of the present invention. The method of Figure 2 is performed by a first base station.

The first base station sends a first access request message to the second base station, where the first base station sends the first user to the second base station, where the Internet content that the first user equipment requests to access is stored in the second base station. The Internet content requested by the device is different, and the first base station is different from the second base station.

202. The first base station receives, by the second base station, the Internet content that is requested by the first user equipment that is sent according to the first access request message.

The base station to which the serving cell of the first user equipment belongs is the first base station, and the first user equipment sends an access request message for the Internet content to the first base station, where the Internet content requested by the first user equipment is first The base station sends to the first user equipment. The base station to which the serving cell of the first user equipment belongs may be referred to as the serving base station of the first user equipment. A serving base station of a user equipment refers to a base station responsible for a Radio Resource Control (RRC) connection between the user equipment and the network side. At the serving base station, there is at least one cell. A cell covered by the serving base station by the user equipment is referred to as a serving cell. The Internet content is a file that is obtained by the second base station from the Internet. Optionally, the Internet content includes, but is not limited to, a file such as a video, an audio, a webpage multimedia, or a text.

In the embodiment of the present invention, when the Internet content requested by the first user equipment is stored in the second base station, the first base station acquires, from the second base station, the Internet content requested by the first user equipment to be sent to the first user equipment, where A base station is different from the second base station in that a plurality of base stations are shared to share the stored Internet content. Since a plurality of base stations store larger capacity than a single base station, the access hit rate of the Internet content stored by the base station can be increased, and the storage utilization rate can be improved, thereby effectively saving transmission overhead and reducing delay time.

Optionally, as an embodiment, before step 201, the first base station may determine whether the Internet content requested by the first user equipment is stored in a base station of the base station set, where the base station set includes at least two base stations, including a first base station and a second base station, where the second base station refers to some other base station in the set of base stations except the first base station, and any two base stations in the set of base stations can be routed Connected to the switch or switch. Alternatively, the function of the router or switch between the two base stations can be implemented by the third base station.

It should be understood that the embodiments of the present invention are not limited to the manner in which the base stations are connected. It should be understood that the two base stations that are interacting are not limited to the adjacent geographical locations, and the same base station may be included in different base station sets.

It should be noted that the communication between the base station and the base station may adopt an IP (Internet Protocol) protocol. The set of base stations may form a mesh network, and specifically includes: The two base stations in the set of base stations can mutually interact with each other, and the functions of the storage internet contents of the base stations in the set of base stations are equivalent. It should be understood that the format of the message exchanged between the base stations or between the base station and the user equipment and the interface form used by the base station to exchange messages between the base stations are not limited.

Optionally, in an implementation manner, the first base station stores a content directory table, where the content directory table records an identifier (such as Internet content) of the Internet content (including the Internet content requested by the first user equipment) stored by the second base station. Name) and storage address. The content directory table is used by the base station to locate a storage location of the Internet content requested by the user equipment, and includes: used to query whether the Internet content requested by the first user equipment is stored in a base station of the base station set and in which base station is stored. . The identification of Internet content is used to uniquely identify Internet content. Specifically, the storage address in the content directory table is used to determine in which base station the Internet content requested by the first user equipment is stored, and the storage address may include the identifier of the second base station and the IP of the second base station (Internet Protocol). At least one of an address and the like.

It should also be noted that the resources (Internet content) in the Internet can be described by a URL (Uniform Resource Locator). For convenience in storage and searching in the base station, the URL can be mapped to a hash function. The one-dimensional sequence ID is used as the identifier of the cache resource. Therefore, the content directory table can be composed of a plurality of entries, each of which can be composed of an Internet content identifier (such as a sequence ID of a cache resource) and an address where the Internet content is actually stored (such as an IP address of a base station). When the base station obtains the resource requested by the user equipment (URL), it maps to the sequence ID according to the hash algorithm, and then finds the location of the entry in the content directory table, thereby knowing the specific storage location.

For example, the second base station sends the identifier of the Internet content stored by the second base station to the first base station. Preferably, the second base station may broadcast the identifier of the Internet content stored by the second base station to other base stations in the base station set, and the other base stations will Identification and storage address of Internet content stored by the second base station Recorded in their respective content table of contents and stored. The first base station may determine, in the base station, the base station in which the Internet content requested by the first user equipment is stored. For example, the first base station may locate, by using an identifier (or an index function of the content directory table), the Internet content requested by the first user equipment to be stored in the second base station. Optionally, the content directory table stored by the first base station further records an identifier and a storage address of the Internet content stored by the first base station.

Preferably, the first base station receives the message that the first user equipment requests to access the Internet content, and the first base station determines, according to the stored content directory table, the storage address of the Internet content that the first user equipment requests to access, first determining whether there is storage. In the local base station (first base station), if not stored in the local base station, it is determined whether it is stored in other base stations (e.g., the second base station) of the set of base stations. When it is determined that the Internet content requested by the first user equipment is stored in the second base station according to the content directory table, the Internet content requested by the first user equipment from the second base station is sent to the first user equipment.

It should be noted that the content directory table stored by the first base station may be a local content directory table, and record the identifier of the Internet content stored by a part of the base stations (including the second base station) in the set of base stations and the corresponding storage address; The content directory table may also be a global content directory table, which records the identifier of the Internet content stored by each base station in the base station set and the corresponding storage address. The recording form of the content directory is not limited in the embodiment of the present invention. The content directory table is used by the base station to locate the storage location of the Internet content requested by the user equipment.

Optionally, in another implementation manner, the first base station may send a query request message to the control server, where the query request is used by the control server to query the content directory table stored by the control server for the Internet content requested by the first user equipment. Storage address. In the embodiment of the present invention, the control server may be logical, and the function of the control server may be implemented by a certain base station, or may be deployed in other devices except the base station. Of course, the control server may also be an independent device. The embodiment of the present invention is not limited thereto.

For example, the first base station sends the query request to the control server if the local base station does not store the Internet content requested by the first user equipment. When receiving the query request message sent by the first base station, the control server may locate the first user equipment according to the content directory table stored by the control server by querying the information (such as the identifier) of the Internet content requested by the first user equipment in the request message. The location where the Internet content requested to be accessed is stored. When the Internet content requested by the first user equipment that is queried from the content directory table is stored in the second base station, the control server sends a query response message to the first base station, where the query response message carries the queried first user equipment request. Access The Internet content stores information in the second base station. The first base station receiving the query response message may determine that the Internet content requested by the first user equipment is stored in the second base station. The content directory table stored by the control server includes an identifier and a storage address of the Internet content stored by the second base station.

It should be noted that the content directory table stored by the control server may be a partial content directory table, and records the identifiers of the Internet content stored by some base stations (including the second base stations in the base station set) and the corresponding storage addresses. The control server may be shared by multiple base stations in the set of base stations, that is, other base stations in the set of base stations may also implement the implementation manner of the first base station. Accordingly, the content directory table stored by the control server may be a global content directory table. The identifier of the Internet content stored by each base station in the base station set and the corresponding storage address are recorded. The recording form of the content directory table is not limited in the embodiment of the present invention. The content directory table stored by the control server is used by the control server to locate the storage location of the Internet content requested by the user equipment according to the query request message sent by the base station.

Optionally, the control server may send the unqueried query response message to the first base station when the Internet content requested by the first user equipment that is not queried from the content directory table is stored in any one of the base stations of the base station set. No action.

Through the foregoing solution, when the base station of the serving cell requests the first user equipment of the first base station to access the Internet content, when the Internet content requested to be accessed is stored in other base stations of the base station set, the first base station may locate the storage of the Internet content requested to be accessed. The location, so that the storage space of other base stations can be utilized, the storage utilization rate is increased, and the access hit rate of the Internet content stored by the base station is increased, and the first user equipment that is not stored in the local base station is requested to access the Internet content without obtaining the access from the Internet network. Thereby effectively saving transmission overhead and reducing delay time.

Optionally, as another embodiment, the first base station may update the Internet content stored by the local base station, and may store the first user equipment under the local base station to request more access times (the number of accesses is greater than a certain number of thresholds, which may be first The base station performs statistics, and the second base station can also perform statistics on the Internet content (also referred to as "hotspot content"). Here, the number of times the Internet content requested by the first user equipment is requested to be accessed may be that the Internet content is first. The sum of the number of times that all user equipments served by the base station request the Internet content.

Specifically, when the number of times that an Internet content (such as Internet content W) is accessed is greater than a certain threshold in a statistical period, the Internet content W may be migrated from the second base station to the first base station, that is, from the second base station. The data is deleted and stored in the first base station, and the stored information of the corresponding Internet content W can be updated. There are a variety of specific migration processes, such as: Optionally, in storage When the first user equipment requests the access to the Internet content, the first base station receives the migration request message sent by the second base station, and the migration request message is used to indicate that the first base station stores the Internet content requested by the first user equipment; or And receiving, by the control server, an migrating request message, where the migrating request message is used to indicate that the first base station stores the Internet content requested by the first user equipment.

For example, during a statistical period, the second base station counts the number of requests for the first base station to initiate access to the Internet content W, and the second base station detects the number of requests for the first base station to initiate access to the Internet content W during the statistical period (ie, When the number of times the first base station sends the access request message for accessing the Internet content W is greater than a certain threshold, the second base station may send a migration request message to the first base station, and after receiving the migration request message sent by the second base station, the first base station The Internet content W is stored in the local base station, and the second base station can delete the stored Internet content w.

Of course, the first base station may also count the number of requests for the user equipment under the first base station to access the Internet content w. During the statistics period, the first base station detects that the user equipment under the first base station initiates access to the Internet content. When the number of requests of W is greater than a certain threshold, the first base station may send a migration request message to the second base station, and store the Internet content W in the local base station. After receiving the migration request message sent by the first base station, the second base station deletes the stored Internet content w.

For another example, during the statistical period, the control server counts the first base station to send and query the Internet content.

The number of times of the query request message of the storage address of the W. When the control server detects that the number of times the first base station sends the query request message for querying the storage address of the Internet content W is greater than a certain threshold, the control server may The second base station transmits an migrating request message of the Internet content W and transmits an migrating request message of the Internet content W to the first base station. Accordingly, the control server changes the storage address of the Internet content W from "identification of the first base station" to "identification of the second base station". When the first base station receives the move request message of the Internet content W transmitted by the control server, the first base station stores the Internet content w. When the second base station receives the migration request message of the Internet content W transmitted by the control server, the second base station deletes the stored Internet content w.

For another example, the first base station may store, by the first user equipment, Internet content whose number of accesses is greater than a threshold and that is not stored in other base stations of the set of base stations. Further, after updating the interconnection content stored by the local base station, the first base station may notify other base stations in the base station set in a broadcast manner. Optionally, in a case that the control server stores the content directory table, after the first base station updates the Internet content stored by the local base station, the first base station may notify the control server, specifically, the first base station may use the updated locally stored Internet content. Identification and storage address (such as the first base) The identity of the station or the IP address of the first base station is sent to the control server to control the server to update the content directory table.

It should be noted that, after updating the interconnection content stored by the local base station by a certain base station in the base station set, the other base stations in the base station set may be notified in a broadcast manner. Optionally, in a case that the control server stores the content directory table, after a base station in the base station set updates the interconnection content stored by the local base station, the control server may be notified to control the server to update the content directory table.

Therefore, the storage of the interconnected content by the base station can improve the storage flexibility. The Internet content stored by the base station requests the user equipment under the base station to access a large number of times, thereby effectively reducing the access overhead between the base stations and reducing the delay. .

It should be understood that the above examples are merely exemplary, and that base station updating stored Internet content for whatever reason should fall within the scope of the present invention.

Optionally, as another embodiment, the first base station may also be the role of the second base station. Specifically, the first base station may receive the second access request message sent by the second base station, where the second access request message is used to request the first A base station sends the Internet content requested by the second user equipment, and the first base station sends the Internet content requested by the second user equipment to the second base station according to the second access request message. The Internet content requested by the second user equipment is stored in the first base station, and the base station to which the serving cell of the second user equipment belongs is the second base station. The second base station sends the received Internet content requested by the second user equipment sent by the first base station to the second user equipment.

In addition, the first base station acquires, from the first base station, the Internet content requested by the first user equipment to be sent to the first user equipment, when the Internet content requested by the first user equipment is stored in the first base station. Specifically, whether the Internet content requested by the first user equipment is stored in the first base station may be determined by using a content directory table stored by the first base station, for example, when the first user equipment request is recorded in the content directory table stored by the first base station. When the identifier of the accessed Internet content and the corresponding storage address include the identifier of the first base station, it is determined that the Internet content requested by the first user equipment is stored in the first base station.

Or, the first base station, in the case that the Internet content requested by the first user equipment is not stored in any of the at least two base stations (ie, the base station set), from the original Internet network (ie, via the core network and the controller) Obtaining the Internet content requested by the first user equipment to be sent to the first user equipment. Specifically, the content directory table stored by the first base station may be used to determine whether any base station in the base station set stores the Internet content requested by the first user equipment, for example, when the first base station stores the global content directory table. Recording Internet content requested by the first user device When the identifier is determined, it may be determined that the Internet content requested by the first user equipment is not stored in any base station of the base station set.

Preferably, the first base station receives the message requested by the first user equipment to access the Internet content, and first determines whether the request to access the Internet content is stored in the local base station. If stored in the local base station, directly acquiring the Internet content requested by the first user equipment to be sent to the first user equipment; if not stored in the local base station, determining whether to store other base stations in the base station set (such as the second base station) in. If it is determined that the second base station is stored, the Internet content requested by the first user equipment from the second base station is sent to the first user equipment; if not stored in any base station of the base station set, then the original The Internet content obtained by the first user equipment in the Internet network is sent to the first user equipment. The manner of how to locate the storage address of the Internet content that the first user equipment requests to access is as described above, and details are not described herein again.

3 is a flow chart of a method for storing Internet content according to another embodiment of the present invention. The method of Fig. 3 is executed by the second base station and corresponds to the method of Fig. 2, and thus the description overlapping with the embodiment of Fig. 2 will be omitted as appropriate.

301. The second base station receives a first access request message sent by the first base station, where the Internet content requested by the first user equipment is stored in the second base station, where the first access request message is used to request the second base station to send the first user. The Internet content requested by the device is different, and the first base station is different from the second base station.

302. The second base station acquires, according to the first access request message, the Internet content requested by the first user equipment to be sent to the first base station.

Optionally, the Internet content is a file that is obtained by the second base station from the Internet, and is not limited to the video, the audio, the webpage multimedia, or the text.

In the embodiment of the present invention, the second base station receives the access request message sent by the first base station, and obtains the Internet content requested by the first user equipment that is stored by the second base station, and sends the Internet content to the first base station, where the first base station is different from the second base station, so that the first base station A base station can utilize the storage space of the second base station to implement sharing of the respective stored Internet content by the plurality of base stations. Since the storage capacity of a plurality of base stations is larger than that of a single base station, the access hit rate of the Internet content stored by the base station can be increased, and the storage utilization rate can be improved, thereby effectively saving transmission overhead and reducing delay time.

Optionally, as an embodiment, before step 301, the second base station may send, to the first base station, an identifier of the Internet content stored by the second base station. Preferably, the second base station may broadcast the identifier of the Internet content stored by the second base station to other base stations in the set of base stations (including the foregoing first base) Station;), the other base station records the identifier and the storage address of the Internet content stored by the second base station in respective content directory tables and stores them. The first base station may locate the Internet requested by the first user equipment by using an identifier (or an index function of the content directory table), because the content directory table stored by the first base station records the identifier and the storage address of the Internet content stored by the second base station. The content is stored in the second base station.

Optionally, as another embodiment, before step 301, the second base station may send, to the control server, an identifier of the Internet content stored by the second base station. The control server records the identification and storage address of the Internet content stored by the second base station in the content directory table and stores it. When the first base station sends the query request message to the control server, the control server may store the Internet content requested by the first user equipment that is queried from the content directory table, and store the Internet content in the second base station, and request the accessed first user equipment to request access. The information stored in the second base station by the Internet content is transmitted to the first base station.

It should be noted that the content directory table stored by the control server may be a partial content directory table, and records the identifiers of the Internet content stored by some base stations (including the second base stations in the base station set) and the corresponding storage addresses. The control server may be shared by multiple base stations in the set of base stations, that is, other base stations in the set of base stations may also implement the implementation manner of the second base station. Accordingly, the content directory table stored by the control server may be a global content directory table. The identifier of the Internet content stored by each base station in the base station set and the corresponding storage address are recorded. The record format of the content directory table is not limited in the embodiment of the present invention. The content directory table is used to control the server to locate the storage location of the Internet content requested by the first user equipment according to the query request message sent by the base station.

Through the foregoing solution, the second base station sends the identifier of the Internet content stored by the second base station to the first base station or the control server, where the base station of the serving cell requests the access to the Internet content when the first user equipment of the first base station requests access to the Internet content. When the content is stored in the second base station, the first base station can locate the storage location of the Internet content that is requested to be accessed, so that the storage space of the second base station can be utilized to improve the storage utilization rate and increase the access hit ratio of the Internet content stored by the base station, without Acquiring from the Internet network that only the first user equipment not stored in the local base station requests access to the Internet content, thereby effectively saving transmission overhead and reducing delay time.

Optionally, as another embodiment, the second base station may update the Internet content stored by the local base station, and may store the Internet content that the first user equipment under the local base station requests a large number of access times (the number of accesses is greater than a certain threshold). It is also called "hot spot content". It can also "move out" other base stations (such as the first base station) to request Internet content with a large number of accesses, that is, the second base station deletes Internet content that other base stations request more access times, and other base stations. To store. Here, the first use The number of times the Internet content requested by the user device is requested to be accessed may be the sum of the number of times the Internet content is requested by all user devices served by the first base station.

For example, when the number of times that an Internet content (such as Internet content W) is accessed is greater than a certain threshold during a statistical period, the Internet content W may be migrated from the second base station to the first base station, that is, deleted from the second base station. And stored in the first base station, at this time, the stored information of the corresponding Internet content W can be updated. The specific migration process may be performed in multiple manners, for example: in a statistical period, the second base station counts the number of requests for the first base station to initiate access to the Internet content W, and during the statistical period, the second base station detects the first base station for statistics. Number of requests to initiate access to Internet content w

The second base station may send a migration request message to the first base station after the first base station receives the migration request message sent by the second base station, that is, the number of times the first base station sends the access request message for accessing the Internet content W is greater than a certain threshold. The Internet content W is stored in the local base station, and the second base station can delete the stored Internet content w.

Further, after updating the interconnection content stored by the local base station, the second base station may notify other base stations in the base station set in a broadcast manner. Optionally, in a case that the control server stores the content directory table, the second base station may notify the control and storage address (such as the identifier of the second base station or the IP address of the second base station) after updating the Internet content stored by the local base station. Sending to the control server, or the second base station may send an indication message that the Internet content W stores the address changed from the second base station to the first base station to the control server, so as to control the server to update the content directory table.

Optionally, before the second base station deletes the Internet content requested by the first user equipment requested by the first base station, the second base station receives the mobility request message sent by the control server, where the mobility request message is used to indicate that the second base station deletes The Internet content requested by the first user equipment stored by the second base station. For details, refer to the embodiment of FIG. 2, and details are not described herein again.

Of course, the second base station can also function as the first base station. For specific implementation, refer to The embodiments are not described herein.

4 is a flow chart of a method for storing Internet content according to still another embodiment of the present invention. The method of Fig. 4 is executed by the control server and corresponds to the methods of Figs. 2 and 3, and thus the description overlapping with the embodiment of Figs. 2 and 3 will be omitted as appropriate.

401. The control server receives a query request message sent by the first base station, where the query request message is used by the request control server to query, from the content directory table stored by the control server, a storage address of the Internet content requested by the first user equipment request.

402. The control server queries, according to the query request message, the storage address of the Internet content requested by the first user equipment from the content directory table stored by the control server.

403. The control server sends a query response message to the first base station, where the query response message carries information that the Internet content requested by the first user equipment that is accessed by the control server is stored in the second base station, so that the first base station determines the first information according to the query response message. The Internet content requested by the user equipment is stored in the second base station, and the first base station is different from the second base station.

Optionally, the Internet content is a file that is obtained by the second base station from the Internet. The Internet content includes, but is not limited to, a video, an audio, a webpage multimedia, or a text.

In the embodiment of the present invention, the control server may be logical, and the function of the control server may be implemented by a certain base station, or may be deployed in other devices except the base station. Of course, the control server may also be an independent device. The embodiment of the present invention is not limited thereto.

In the embodiment of the present invention, the control server receives the query request message sent by the first base station, and queries the content directory table stored by the control server to query the storage address of the Internet content requested by the first user equipment, and requests the first user equipment to request access. The information stored in the second base station of the Internet content is sent to the first base station, so that the first base station determines that the Internet content requested by the first user equipment is stored in the second base station, and the first base station is different from the second base station. Therefore, a plurality of base stations are shared by the control server to share the respective stored Internet contents. Since the storage capacity of a plurality of base stations is larger than that of a single base station, the access hit rate of the Internet content stored by the base station can be increased, and the storage utilization rate can be improved, thereby effectively saving transmission overhead and reducing delay time.

Optionally, as an embodiment, before step 401, the control server may receive, by the second base station, an identifier of the Internet content stored by the second base station, where the control server records the identifier and the storage address of the Internet content stored by the second base station. In the content table of contents.

It should be noted that the content directory table stored by the control server may be a local content directory. A table records an identifier of the Internet content stored by a part of the base stations in the set of base stations (including the second base station in the set of base stations) and a corresponding storage address. The control server may be shared by a plurality of base stations in the set of base stations, that is, other base stations in the set of base stations may also perform the implementation of the first base station (or the second base station described above). The directory table stored by the control server may be a global content directory table, and records the identifier of the Internet content stored by each base station in the base station set and the corresponding storage address. The record format of the content directory table is not limited in the embodiment of the present invention. The content directory table is used to control the server to locate the storage location of the Internet content requested by the first user equipment according to the query request message sent by the base station.

Through the foregoing solution, the control server can locate the storage location of the Internet content requested to be accessed, so that multiple base stations share the stored Internet content, improve the storage utilization rate, and increase the access hit rate of the Internet content stored by the base station, without obtaining the Internet network. Only the first user equipment not stored in the local base station requests access to the Internet content, thereby effectively saving transmission overhead and reducing delay time.

Optionally, as another embodiment, the control server may update the stored content directory table. Optionally, after a certain base station in the base station set updates the interconnection content stored by the local base station, notify the control server, and the control server updates accordingly. Content table of contents.

For example, when the number of times that an Internet content (such as Internet content W) is accessed is greater than a certain threshold during a statistical period, the Internet content W may be migrated from the second base station to the first base station, that is, deleted from the second base station. And stored in the first base station, at this time, the stored information of the corresponding Internet content W can be updated to the control server. The specific migration process may be performed in multiple manners, for example, when the number of times that the second base station detects that the first base station initiates access to the Internet content W is greater than a certain threshold in the statistical period, the second base station sends the migration to the first base station. The request message, the second base station "migrates" the Internet content W, is stored by the first base station, and sends an indication message to the control server that the Internet content W is changed from the second base station to the first base station, and the control server receives the indication message. , changing the storage address of the Internet content W from "identity of the first base station" to

"Identification of the second base station". Alternatively, the stored decision of the Internet content to be migrated between the base stations can be unified by the control server.

Optionally, when the control server detects the statistics, the first base station sends an inquiry during the statistical period. When the number of times the message is greater than the number threshold, the control server sends an migrating request message to the first base station and sends a escrow request message to the second base station, and the control server updates the content directory table stored by the control server, where the migrating request The message is used to indicate that the first base station stores the Internet content requested by the first user equipment, and the migrating request message is used to instruct the second base station to delete the Internet content requested by the first user equipment stored by the second base station.

For example, during a statistical period, the control server counts the number of times the first base station sends a query request message for querying the storage address of the Internet content W. During the statistical period, the control server detects that the first base station sends a query for the storage address of the Internet content w. When the number of the query request messages is greater than a certain number of thresholds, the control server may send the move request message of the Internet content W to the second base station and send the move request message of the Internet content W to the first base station. Accordingly, the control server changes the storage address of the Internet content W from "identification of the first base station" to "identification of the second base station". When the first base station receives the move-in request message of the Internet content W transmitted by the control server, the first base station stores the Internet content w. When the second base station receives the migration request message of the Internet content W transmitted by the control server, the second base station deletes the stored Internet content w.

Therefore, the control server updates the stored content directory table, and accordingly, the base station updates the stored interconnection content, thereby improving storage flexibility, and the Internet content stored by the base station requests the user equipment under the base station to access a large number of times. It effectively reduces the access overhead between base stations and reduces the delay.

Embodiments of the present invention will be described in detail below with reference to the embodiments of Figures 5-8.

FIG. 5 is a schematic structural diagram of a base station set according to an embodiment of the present invention. In FIG. 5, two sets of base stations are depicted. The set of base stations 1 includes five base stations which are base stations A1, Bl, Cl, D1 and El respectively. The base station set 2 includes five base stations which are base stations CI, B2, C2 and D2, respectively. And E2, any two base stations in each base station set can be connected through a router or a switch. It should be understood that, in the embodiment of the present invention, the number of multiple base stations included in the set of base stations and the manner in which the base stations are connected are not limited. It should also be understood that the two base stations that are interacted are not limited to the adjacent geographical locations. A base station can be included in a different set of base stations, such as base station C1. The set of base stations may constitute a mesh network, and may specifically include: any two base stations in the set of base stations may mutually interact with each other, and functions of storing Internet content of each base station in the base station set are equivalent.

Optionally, each base station in each base station set stores Internet content, and correspondingly stores a content directory table, where the content directory table records an identifier of the Internet content stored by each base station in the base station set and a corresponding storage address. Preferably, different base stations store different Internet content. In this way, the storage utilization of the base station can be improved. Alternatively, each base station set stores the content directory table in a control server (such as the control server S1 of the base station set 1 or the control server S2 of the base station set 2). Multiple base stations can share their stored Internet content.

It should be understood that the control server may be logical. The function of the control server may be implemented by a certain base station, or may be deployed in other devices than the base station. Of course, the control server may also be an independent device. This example is not limited to this.

It should also be understood that some of the base stations in the set of base stations may store only the content directory table without storing the Internet content, which is not limited by the embodiment of the present invention.

The embodiment of the present invention will be described in detail below by taking the base station set 1 in Fig. 5 as an example. As shown in FIG. 6, the base station of the serving cell of the UE 601 and the UE 602 is the base station Al, and the base station of the serving cell of the UE 603 is the base station D1.

Step 1: The UE 601 initiates a request to access the Internet content W to the base station A1. Optionally, the base station A1 learns from the content directory table currently stored in the base station A1 that the Internet content requested by the UE 601 is not stored in any base station of the base station set 1, and the Internet content is obtained from the Internet network 604 and sent to the UE 601. . Alternatively, the base station A1 sends an inquiry request message to the control server S1 in the case that it is determined that the Internet content W requested by the UE 601 is not stored in the base station A1, and the base station A1 learns that the control server does not query through the query response message sent by the control server S1. The Internet content W is stored in other base stations of the base station set 1, and the Internet content is acquired from the Internet network 604 and transmitted to the UE 601.

Step 2: The base station A1 stores the Internet content W obtained from the Internet network 604. Optionally, broadcast to other base stations (base stations B1, Cl, D1, and El) in the set of base stations 1, and other base stations may record the Internet content identifier W and the identifier A1 of the storage address base station A1 in respective content directory tables and store Alternatively, the base station A1 notifies the control server S1 that the Internet server identifier W and the identifier A1 of the storage address base station A1 are recorded in the content directory table and stored.

In step 3, the UE 602 initiates a request to access the Internet content W to the base station A1. Since the base station Al stores the Internet content W, the base station A1 transmits the stored Internet content W to the UE 602. Therefore, the base station A1 does not need to obtain the Internet content W from the Internet network and transmits it to the UE 602, thereby saving transmission overhead and reducing delay time.

Or

The UE 603 initiates a request to access the Internet content W to the base station D1. Optionally, the base station D1 is based on The station D1 may, when the local base station stores the Internet content, send the query request message to the control server S1, the control server S1 may request the access to the Internet content by the UE 603 in the query request message, according to the content stored by the control server S1. The directory table locates the Internet content W and stores it in the base station A1, and returns a query response message to the base station D1. The query response message carries the identifier of the queried base station A1, and the base station D1 determines that the Internet content W is stored in the base station A1 according to the query corresponding message. The base station D1 sends an access request message to the base station A1, and the identifier W of the Internet content that the UE 603 requests to access may be carried in the request message. The base station A1 transmits the Internet content W to the base station D1, and returns it to the UE 603 by the base station D1.

When the base station of the serving cell requests the user equipment of the first base station to access the Internet content, when the Internet content requested to be accessed is stored in other base stations of the base station set, the first base station may locate the storage location of the Internet content requested to be accessed. Therefore, the storage space of other base stations can be utilized, the storage utilization rate can be improved, and the access hit rate of the Internet content stored by the base station can be increased, and the user equipment that is not stored in the local base station is requested to access the Internet content, thereby effectively saving. Transfer overhead and reduce latency.

FIG. 7 is a schematic structural diagram of a base station updating stored Internet content according to an embodiment of the present invention.

The base station of the serving cell of the UE 701 and the UE 702 is the base station D1, the base station of the serving cell of the UE 703 is the base station A1, and the Internet content W is stored in the base station A1.

The UE 701 and the UE 702 in the base station D1 initiate a request to access the Internet content W to the base station D1. The base station D1 obtains the Internet content W from the base station A1 and sends it to the UE 701 and the UE 702. The specific implementation process may refer to the above, and details are not described herein again. That is, the UE 701 and the UE 702 need to acquire the Internet content W through the transmission access between the base station D1 and the base station A1. The UE 703 under the base station A1 initiates a request to access the Internet content W, and the base station A1 can directly send the Internet content W stored by the local base station to the UE 703. When the base station A1 detects that the number of times the access to the Internet content W from the base station D1 is greater than the number of times the UE local to the base station A1 initiates access to the Internet content W, the base station A1 may transmit a migration request of the Internet content W to the base station D1. After receiving the migration request of the Internet content W sent by the base station A1, the base station D1 stores the Internet content W, and the base station A1 can delete the locally stored Internet content W.

Optionally, after updating the stored Internet content, the base station A1 broadcasts to other base stations of the base station set 1, and the other base stations may update the stored content directory table correspondingly, and delete the records in which the Internet content W is stored in the base station A1. Similarly, after updating the respective stored Internet content, the base station D1 also broadcasts to other base stations of the base station set 1, and other base stations can update the stored internals accordingly. The directory table, adding Internet content W is stored in the record of the base station D1. Alternatively, after updating the respective stored Internet contents, the base station A1 and the base station D2 notify the control server S1 that the control server S1 updates the content directory table, and changes the Internet content W stored in the base station A1 to the Internet content W and stores it in the base station D1. Alternatively, the stored decision of the Internet content to be migrated between the base stations may be unified by the control server S1. For example, when the control server S1 detects that the number of times the access to the Internet content W is initiated from the base station D1 is greater than the number of times the UE local to the base station A1 initiates access to the Internet content W, the control server may send an outgoing request of the Internet content W to the base station A1, the base station A1. After receiving the migration request of the Internet content W, the migration request of the Internet content W is transmitted to the base station D1.

Therefore, if the Internet content stored by the base station requests the user equipment under the base station to access a large number of times, the access overhead between the base stations can be effectively reduced, and the delay is reduced.

It is to be understood that the above examples are merely illustrative and are not intended to limit the scope of the invention. It should also be understood that other base stations in the set of base stations may also perform operations of base station A1 or base station D1.

The processor 1402 is further configured to record the identifier and the storage address of the Internet content stored by the second base station received by the receiver 1401 in the content directory table. Line updates. Specifically, when the number of times that a certain Internet content (such as Internet content W) is accessed is greater than a certain threshold in a statistical period, the Internet content W may be migrated from the second base station to the first base station, that is, from the second base station. Deleted and stored in the first base station, and accordingly, the processor 1402 is new.

Optionally, the processor 1402 is specifically configured to: when the number of times that the first base station sends the query request message by the control server to the statistics is greater than the threshold, the content directory table stored by the control server is updated. The transmitter 1403 is further configured to: send an migrating request message to the first base station and send a migrating request message to the second base station. The migrating request message is used to instruct the first base station to store the Internet content requested by the first user equipment, and the migrating request message is used to instruct the second base station to delete the Internet content requested by the first user equipment stored in the second base station.

It should be noted that the content directory table stored by the control server may be a partial content directory table, and records the identifiers of the Internet content stored by some base stations (including the second base stations in the base station set) and the corresponding storage addresses. The control server may be shared by a plurality of base stations in the set of base stations, i.e., other base stations in the set of base stations may also implement the implementation of the first base station (or the second base station described above). The directory table stored by the control server may also be a global content directory table, which records the identifier of the Internet content stored by each base station in the base station set and the corresponding storage address. The recording form of the content directory table is not limited in the embodiment of the present invention.
