The priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a paging method, a home base station, a home base station gateway, and a communication system.

Background technique

With the rapid development of Internet (Internet) services and the wide application of broadband access networks and wireless networks, high-speed and convenient access to the network is receiving widespread attention. Users need high-speed, convenient, low-cost wireless data services using handheld wireless devices. At the same time, with the continuous growth of third-generation mobile communication technology (3G) users and the deepening of Long-Term Evolution (LTE) research, as a typical representative of private base stations, home base stations (HNB: Home NodeB) or indoor access points ( AP: Access Point), is receiving more and more attention. A home base station refers to a small, small base station for home or office. It may be completely private. It can also be opened to the public for use with different priorities and permissions. Its ownership is private, not government or Operator; its use may be a small range of users, but also a wide range of users.

Paging is performed according to location management. The existing Wideband Code Division Multiple Access (WCDMA) system uses a location area (LA: Location Area) and a routing area (RA: Routing Area). ) for location management. The location area and the routing area are composed of a plurality of cells, that is, a group of cells; the core network (CN: Core Network) plans the location area/routing area according to the geographical location. If the user equipment (UE: User Equipment) changes the location area or routing area during the mobile process (location area/routing area change), the user equipment initiates a location update process (location area update or routing area update procedure), notifying the core Net its own new location area or routing area. For the existing circuit (CS: Circuit switched) domain service, the core network uses the location area for location management. In one location area, the core network uses the Temporary Mobile Station Identifier (TMSI) to uniquely represent a user. The device, the core network uses a temporary mobile station identity or an International Mobile Station Identifier (IMSI) to page the user equipment within its location area. For existing groupings (PS: Packet Switched) service, the core network uses the routing area for location management. In a routing area, the core network uses the packet temporary mobile station identifier (P-TMSI: Packet TMSI) to uniquely represent a user equipment, and the core network uses The packet temporary mobile station identity or international mobile subscriber identity code pages the user equipment within the routing area in which it is located.

The basic process for the core network to page the user equipment is as follows: the core network needs to page the user equipment, and the core network queries the location area/routing area where the user equipment is located to page, and sends a paging message to the user. All radio network controllers (RNCs) under the location area/routing area where the device is located, the message contains the paging domain information (packet domain or circuit domain), and the identity of the paging user equipment (such as international mobile User identification code, etc., paging area information to be paged, paging reason, etc., may include temporary identification (packet temporary mobile station identification of the packet domain, temporary mobile station identification of the circuit domain, etc.); wherein, the paging area The information may be a LAI丄ocation Area Identity or a RIA: Routing Area Identity.

According to the location area identifier or the routing area identifier carried in the paging (PAGING) message, the radio network controller searches for all cells corresponding thereto, and then calculates the paging moment according to the international mobile subscriber identity of the user equipment, and paging When the time comes, the paging message is sent to the cells to page the corresponding user equipment, and the paging message may be a paging type paging type message, a paging type 2 message, or the like. If there is no location area identifier or routing area identifier in the paging message, the radio network controller sends a paging message to all cells of the radio network controller.

The traditional cell is deployed by the operator and can be regarded as open to all users. All users have the right to reside in the cell of the operator, or in some location areas/routing areas, because the core network only knows The paging area (location area or routing area) where the user equipment is located does not know the cell where the user equipment is located, and all the cells under the paging area need to be paged; and the home base station is deployed by the user, and only the service is provided. Few users, other users are not allowed to access. Since the home base station is to be compatible with existing user equipment and core network to the greatest extent, it must be planned into a certain paging area (location area/routing area). Therefore, when the core network pages the user equipment in the paging area including the home base station, the core network sends a paging message to all the radio network controllers and the home base station under the paging area, and the home base station will receive all the paging messages. Paging is processed and an air interface paging message is sent on the air interface, which also includes paging for some user equipments that are not authorized under the home base station, thereby causing waste of radio resources.

detailed description

The present invention will be further described in detail below with reference to the drawings and embodiments.

FIG. 1 is a flowchart of a first embodiment of a paging method according to an embodiment of the present invention, and describes a process performed by a home base station, including:

Step 101: Receive a paging message; the paging message includes an identifier of the user equipment that needs to be paged; and the received paging message may be from a core network node, such as a mobile switching center server (MSC:

Mobile Switching Centre Server), serving General Packet Radio Service Support Node (SGSN), etc.; or from Home Base Station Gateway (HNB GW: Home Node B Gateway);

The paging message may include not only the identifier of the user equipment that needs to be paged, but also the domain information (packet domain or circuit domain) of the paging, the paging area information to be paged, the reason for paging, and the like; The paging area information may be a location area identifier, a routing area identifier, or the like. The paging area in the embodiment of the present invention may be a location area or a routing area, but the embodiment of the present invention does not limit the paging area to only the location area. Or routing area;

The identifier of the user equipment that needs to be paged may be a universal identifier of the user equipment that needs to be paged, such as the country. Mobile subscriber identification code, etc.; may also be a temporary identifier, such as a packet temporary mobile station identifier of a packet domain, a temporary mobile station identifier of a circuit domain, etc.;

Step 102: Determine whether the user equipment that needs to be paged is authorized, and the user equipment that needs to be paged corresponds to the identifier of the user equipment that needs to be paged; if yes, go to step 103; if no, go to step 104;

Whether the user equipment is authorized may be determined by the saved list of authorized user equipments. If the identifier of the user equipment is recorded in the list of authorized user equipments, the instructions are authorized; otherwise, if there is no record in the list of authorized user equipments, Then the description is not authorized;

Step 103: Paging the user equipment; ending the process;

Specifically, the user equipment may be advertised by sending an air interface paging message in the air interface. The air interface paging message may be a paging type 1 message or a paging type 2 message, or may be other newly defined air interface paging messages.

Step 104: No paging is performed on the user equipment; the process ends.

It can be seen from the above that before the paging of the user equipment, the user equipment is first authorized to judge whether the user equipment is authorized, and only the authorized user equipment is paged, so that the home base station does not need to perform all paging messages received. The processing can reduce the paging area and reduce the waste of radio resources such as air interface resources and system interface resources.

2 is a signaling flow of a second embodiment of a paging method according to an embodiment of the present invention, and describes a process for determining whether a user equipment is authorized by a home base station, including:

Step 201: The core network advertises the user equipment in the paging area where the user equipment is located according to the requirement; the paging area may be a location area, a routing area, and the like. This embodiment is described by using a location area; Two radio network controllers (radio network controller 1 and radio network controller 2), four home base stations (home base station 1, home base station 2, home base station 3, and home base station 4); the core network sends a paging message to the The radio network controller 1-2 under the location area, the home base station 1~4; the paging message includes the paging domain information (packet domain or circuit domain), the identifier of the paging user equipment (International Mobile Subscriber Identity) and / Or the temporary mobile station identifier, the location area identifier to be paged, the paging reason, and the like; if the paging area is paged, the user equipment carried in the paging message is temporarily identified as the packet temporary mobile station identifier, and the paging area information Is the routing area identifier.

Step 202: If the paging message has a location area identifier, the wireless network controller 1~2 points to the finger The air interface paging message is sent to all the cells in the location area; if there is no location area identifier in the paging message, the radio network controller sends an air interface paging message to all the cells of the radio network controller; The call message is described as a paging type 1 message.

Step 203: The home base station 1~4 authenticates the paging message according to the list of authorized user equipments saved by itself, according to the identifier of the user equipment (the international mobile subscriber identity and/or the temporary mobile station identifier in the paging message). Determining whether the user equipment to be paged is authorized, and deciding whether to issue an air interface paging message; if the user equipment is not authorized under the home base station 2~4, it is authorized under the home base station 1; therefore, the home base station 2~4 does not Send an air interface paging message.

There is no time sequence in step 202 and step 203.

Step 204: The home base station 1 sends an air interface paging message to page the user equipment; the air interface paging message that is sent may be a paging type 1 message.

As can be seen from the above, in the embodiment, the home base station first determines whether the user equipment is authorized before paging the user equipment, and only pages the authorized user equipment, so that the home base station does not need to find all the received information. The call message is processed, so that the paging area can be reduced, and the waste of radio resources such as air interface resources and system interface resources is reduced.

FIG. 3 is a flowchart of a third embodiment of a paging method according to an embodiment of the present invention, and describes a process performed by a core network node or a home base station gateway, including:

Step 301: Obtain an identifier of a user equipment that needs to be paged;

If the execution entity of the process is a home base station gateway, the home base station gateway may obtain the identifier of the user equipment that needs to be paged from the received paging message;

If the execution entity of the process is a core network node, the core network node can determine which user device to page, and thus can obtain the identifier of the user equipment that needs to be paged;

Further, the paging area information of the user equipment that needs to be paged may be further obtained; Step 302: Search for a home base station corresponding to the identifier of the user equipment;

The home base station corresponding to the identifier of the user equipment may be a home base station that is authorized to search for the user equipment. In the embodiment of the present invention, the home base station authorized by the user equipment refers to a home base station that allows the user equipment to access.

Regardless of whether the execution entity of the process is a home base station gateway or a core network node, a list of authorized user equipments of multiple home base stations can be saved; for example, the home base station gateway can save the connections that can be connected thereto. A list of authorized user devices of each home base station, the home base station gateway may also save a list of authorized home base stations of the user equipment.

When searching for the home base station corresponding to the identifier of the user equipment, the user equipment may be searched according to the identifier of the user equipment, and the user base station authorized by the user equipment is queried; or the user equipment may be Identifying a list of authorized home base stations found for the user equipment;

If the paging area information of the user equipment that needs to be paged is obtained, the home base station corresponding to the identifier of the user equipment may be searched in the paging area corresponding to the paging area information, thereby reducing the scope of the search and improving the search. s efficiency;

Step 303: Send a paging message to the discovered home base station corresponding to the identifier of the user equipment. When the main body of the process is the home base station gateway, the home base station gateway can directly send the paging message to the found home base station corresponding to the identifier of the user equipment;

When the execution entity of the process is a core network node, the core network node may directly send a paging message to the found home base station corresponding to the identifier of the user equipment; or may use the home base station gateway to find the identifier of the user equipment that is found by the home base station gateway. The corresponding home base station sends a paging message.

It can be seen from the above that in the embodiment, before sending the paging message to the home base station, the corresponding home base station is searched according to the identifier of the user equipment that needs to be paged, and only the found home base station corresponding to the identifier of the user equipment is sent. Calling the message, so that only the user equipment authorized by the user equipment to page the user equipment, without the user equipment not having the authorized home base station to page the user equipment, thereby reducing the paging area and reducing the air interface resources, The waste of the radio resources such as the system interface resources; further, the paging area information of the user equipment may be further obtained, so that the home base station corresponding to the identifier of the user equipment can be searched only in the paging area corresponding to the paging area information, not only Improve the efficiency of the search, and further reduce the paging area, further reducing the waste of wireless resources such as air interface resources and system interface resources. The home base station in which the user equipment is not authorized in the embodiment of the present invention refers to a home base station that does not allow access by the user equipment.

After receiving the paging message that the paging method is the third processing, the home base station may directly send the air interface paging message to the user equipment in the air interface, or may perform the processing procedure of the paging method in the first embodiment to the user equipment. Paging. The home base station gateway selects a process for the home base station to perform paging according to the identifier of the user equipment that needs to be paged, including:

Step 401: The core network pages the user equipment in the paging area where the user equipment is located according to the requirement; in this embodiment, the paging area is used as the location area; 4: the location area includes two radio network controllers ( Radio network controller 1 and radio network controller 2), four home base stations (home base station 1, home base station 2, home base station 3, and home base station 4); the core network sends a paging message to the radio network control under the location area 1-2, the home base station 1~4; the paging message includes the paging domain information (packet domain or circuit domain), the paging user equipment identifier (International Mobile Subscriber Identity) and/or the temporary mobile station identifier, Call for reasons and other information;

The paging message sent by the core network may further include a location area identifier to be paged;

Step 402: If the paging message has a location area identifier, the radio network controller 1~2 sends an air interface paging message to all cells in the specified location area; if there is no location area identifier in the paging message, the radio network controller An air interface paging message is sent to all cells of the radio network controller; the air interface paging message is assumed to be a paging type 1 message;

Step 403: The home base station gateway authenticates the user equipment according to the list of authorized user equipments of all the home base stations that are saved by the home base station, and may specifically search for the identifier of the user equipment according to the identifier of the user equipment that needs to be paged. Corresponding home base station; if the paging message includes the location area information in which the user equipment is located, it may be in the location area corresponding to the location area information (for example, the paging message does not include the location area information where the user equipment is located, and may default to All home base stations) look up the home base station corresponding to the identity of the user equipment that needs to be paged.

Steps 402 and 403 do not have a sequence of time.

Step 404: The home base station gateway sends only the paging message to the home base station in the location area indicated by the paging message, and the user equipment in the paging message is authorized. It is assumed that the user equipment is not authorized under the home base station 2~4. It is authorized under the home base station 1, and therefore only sends a paging message to the home base station 1.

Step 405: After receiving the paging message from the home base station gateway, the home base station 1 sends an air interface paging message to the user equipment in the air interface; where the paging message is not the paging type 1 message.

As can be seen from the above, in the embodiment, the home base station gateway searches for the corresponding home base station according to the identifier of the user equipment that needs to be paged before sending the paging message to the home base station, and only searches for the found user equipment. The home base station corresponding to the identifier sends a paging message, so that only the user equipment authorized by the user equipment pages the user equipment, and the user equipment does not have the authorized home base station to page the user equipment, thereby narrowing down the search. The paging area reduces the waste of radio resources such as air interface resources and system interface resources. Further, the paging area information of the user equipment can be further obtained, so that the paging area corresponding to the paging area information can be searched only with the user equipment. The identification of the corresponding home base station not only improves the efficiency of the search, but also further reduces the paging area, thereby further reducing the waste of radio resources such as air interface resources and system interface resources. The process of selecting, by the core network node, the paging of the user base station according to the identifier of the user equipment that needs to be paged, includes:

Home base station. It is assumed that the user equipment is not authorized under the home base station 2~4 and is authorized under the home base station 1, so only the paging message is sent to the home base station 1.

The paging message includes the domain information of the paging (packet domain or circuit domain), the identifier of the paging user equipment (International Mobile Subscriber Identity) and/or the temporary mobile station identifier (the packet domain is the packet temporary mobile station identifier, the circuit domain) It is a temporary mobile station identifier), a location area identifier to be paged, a paging reason, and the like; Step 502: If the paging message has a location area identifier, the radio network controller 1~2 will all the cells in the designated location area. The air interface paging message is sent; if there is no location area identifier in the paging message, the radio network controller sends an air interface paging message to all cells of the radio network controller; the air interface paging message is a paging type 1 message. Describe

Step 503: After receiving the paging message, the home base station 1 sends an air interface paging message to the air interface. Calling the user equipment; the air interface paging message is described here as a paging type 1 message. The paging message received by the home base station 1 may be directly from the core network node or from the home base station gateway.

Steps 502 and 503 do not have a sequence of time.

As can be seen from the above, in the embodiment, the core network node searches for the corresponding home base station according to the identifier of the user equipment that needs to be paged before sending the paging message to the home base station, and only searches for the home corresponding to the identifier of the user equipment. The base station sends a paging message, so that only the user equipment authorized by the user equipment to page the user equipment, without the user equipment not having the authorized home base station to page the user equipment, thereby reducing the paging area and reducing the The waste of the radio resource, the system interface resource, and the like; further, the paging area information of the user equipment is further obtained, so that the home base station corresponding to the identifier of the user equipment can be searched only in the paging area corresponding to the paging area information. Not only can the efficiency of the search be improved, but also the paging area can be further reduced, thereby further reducing the waste of radio resources such as air interface resources and system interface resources.
