Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
The description herein takes an example of a long-term evolution self-organizing network in a self-organizing network, and an access network entity under the long-term evolution self-organizing network. Accordingly, on the aforementioned premise, an interface between the source access network Entity and the core network Element (MME) may be an S1 interface, an interface between the source access network Entity and the User Equipment (UE) may be a Uu interface, an interface between the source access network Entity and the second network Element, that is, the access network Entity, may be an interface with the access network Entity, and an interface between the Element Management System (EMS) and the Network Management System (NMS) may be an OAM interface.
An embodiment of a method for establishing a communication connection between network elements is shown in fig. 1:
step 101: and the source access network entity sends a query message comprising the identification of the target access network entity to the intermediate network element.
Step 102: and the source access network entity receives the transport layer address information of the target access network entity sent by the intermediate network element, and the transport layer address information is acquired by the intermediate network element according to the identification of the target access network entity.
In this embodiment, if the intermediate network element itself stores a transport layer address information list for establishing an interface, where the list includes a correspondence between an access network entity identifier and transport layer address information of the access network entity, the intermediate network element may directly obtain the transport layer address information of the access network entity by querying the list and feed the obtained transport layer address information back to the source access network entity; or, if the intermediate network element does not store the transport layer address information list, the intermediate network element acquires the transport layer address information corresponding to the access network entity identifier by inquiring other network elements and feeds back the transport layer address information to the source access network entity.
Step 103: and the source access network entity establishes connection with the target access network entity according to the transport layer address information.
In this embodiment, when the intermediate network element is a core network element,
step 101 specifically includes:
and the source access network entity sends a query message comprising the identification of the target access network entity to the core network element through an S1 interface between the source access network entity and the core network element.
Step 102 specifically includes:
and the source access network entity receives the transport layer address information sent by the core network element through the S1 interface, and the transport layer address information is acquired by the core network element according to the target access network entity identifier. In this embodiment, if the query of the core network element fails, failure information is sent to the source access network entity.
In this embodiment, the method for the core network element to obtain the transport layer address information of the target access network entity according to the target access network entity identifier specifically includes: the core network element sends a query message including the target access network entity identifier to a second core network element through an S10 interface between the core network element and the second core network element;
and the core network element receives transport layer address information sent by the second core network element, wherein the transport layer address information is acquired by the second core network element according to the target access network entity identifier.
In practical application, a core Network element generally does not maintain transport layer addresses of all access Network entities in a whole Public Land Mobile Network (PLMN); generally, a core network element in a core network element group maintains an access network entity identifier connected to the core network element group and a transport layer address thereof for establishing a connection. Therefore, when two access network entities connected to different core network element groups need to establish a connection, a query across core network elements is needed at this time, and therefore an S10 interface between a core network element and a second core network element needs to be defined for a related query.
The scheme for inquiring by crossing the core network elements has stronger functions, so that the source access network entity can more conveniently obtain the required transport layer address information of the target access network entity.
In this embodiment, when the intermediate network element is a network element management system, the acquiring, by the network element management system according to the identifier of the target access network entity, the transport layer address information of the target access network entity includes:
the network element management system sends a query message including a target access network entity identifier to the network management system through an OAM interface between the network element management system and the network management system;
the network element management system receives transport layer address information sent by the network management system, and the transport layer address information is obtained by the network management system according to the target access network entity identification.
In this embodiment, if the query of the network element management system fails, failure information is sent.
In this embodiment, when the intermediate network element is a user equipment, the identifier of the target access network entity included in the query message sent by the source access network entity is specifically: the Physical Cell identity (Phy-CID) or Global Cell Identity (GCI) of the Cell in which the target access network entity is located, where the obtaining, by the user equipment, the transport layer address information body of the target access network entity according to the identity of the target access network entity includes:
and the user equipment reads the transport layer address information sent by the target access network entity through the Uu interface according to the target access network entity identification.
In this embodiment, the transport layer address information may be complete transport layer address information; in order to save air interface resources, the target access network entity can also be a part of the complete transport layer address information as long as the target access network entity can be uniquely identified.
At this time, the sending, by the user equipment, the transport layer address information of the target access network entity to the source access network entity specifically includes:
and when the user equipment judges that the connection can be established between the source access network entity and the target access network entity, the user equipment sends the transport layer address information to the source access network entity.
For the transport layer address information queried by the user equipment, the following schemes are specifically provided:
firstly, the user equipment does not process and sends the read information to a source access network entity;
second, the user equipment may make a corresponding determination and send the filtered information to the access network entity, because the source access network entity does not know whether the connection can be established with the target access network entity before querying, and whether the connection can be established can allow the user equipment to determine. That is to say that the first and second electrodes,
the user equipment reads the broadcast message of the target access network entity, and if the source access network entity and the target access network entity cannot establish connection (for example, two access network entities belong to different core network element pools), although the transport layer address information broadcast by the target access network entity can be read, the information is not sent to the source access network entity.
In an embodiment, step 103 may further include:
the source access network entity inquires other transport layer addresses of the target access network entity through the established connection;
the source access network entity establishes a stream control transport protocol coupling using the other transport layer addresses.
In this embodiment, when the intermediate network element is also an access network entity, here called second access network entity,
step 101 specifically includes:
a source access network entity sends a query message including a target access network entity identifier to a second access network entity;
step 102 specifically includes:
and receiving transport layer address information sent by the access network entity of the second access network entity, wherein the transport layer address information is acquired by the access network entity of the second access network entity according to the identification of the target access network entity.
In this embodiment, the second access network entity may obtain the transport layer address information from another access network entity or a core network entity.
In this embodiment, if the access network entity fails to perform the query, failure information is sent.
The message carrying various required information, which needs to be used in this embodiment, may add parameters to the existing message, or may use a newly added message. In step 102, the intermediate network element may maintain and store the transport layer address information having a corresponding relationship with the access network entity identifier, and in this case, the intermediate network element queries the transport layer address information required by the source access network entity in its own storage unit according to the access network entity identifier. The intermediate network element may also not store the transport layer address information itself, but dynamically query the target access network entity according to the target access network entity identifier to obtain the transport layer address information of the target access network entity.
Now, a request Handover (Handover Required) message including query information as a parameter is described again in detail, which is based on the premise that the intermediate network element itself does not store transport layer address information:
a parameter, for example, a parameter named Transport Address Query (Transport Address Query), is added to a Transparent Container (Transparent Container) sent by the source access network entity to the target access network entity in the Handover Required message.
The core network element transmits the Transport Address Query parameter to the target access network entity through the Handover Request message;
if the target access network entity receives the Transport Address Query parameter, it transmits its Transport layer Address information for establishing connection in a Handover Request acknowledgement (Handover Request Acknowledge) message, for example, adding the parameter in a transparent container sent by the target access network entity to the source access network entity.
The source access network entity carries the transport layer address for establishing connection of the target access network entity in the Handover Command (Handover Command) message received from the core network element, and establishes connection with the target access network entity.
The message carrying various required information, which needs to be used in this embodiment, may add parameters to the existing message, or may use a newly added message.
In the embodiment of the invention, the intermediate network element acquires the transport layer address information of the target access network entity or the source access network entity according to the network element identifier, and the communication connection between the source access network entity and the target access network entity is realized according to the transport layer address information.
The second embodiment of the method for establishing a communication connection between network elements is as follows:
step 201: the target access network entity receives a second request message sent by the intermediate network element, wherein the second request message comprises the transport layer address information of the source access network entity;
step 202: and the target access network entity establishes connection with the source access network entity according to the transport layer address information of the source access network entity.
The intermediate network element in the embodiment of the present invention may be one of a core network element, an access network entity, a user equipment, a network element management system, and the like.
In the present embodiment, the first and second electrodes are,
step 201 is preceded by:
a source access network entity sends a first request message for establishing connection with a target access network entity to an intermediate network element, wherein the first request message comprises a source access network entity identifier;
at this time, the intermediate network element obtains the transport layer address information of the source access network entity according to the source access network entity identifier in the first request message.
In this embodiment, step 201 further includes:
the source access network entity sends a first request message for establishing connection with the target access network entity to the intermediate network element, wherein the first request message comprises transport layer address information of the source access network entity.
The following describes the present embodiment by taking a Handover Required message including query information as an example, and this example is based on the premise that the intermediate network element itself does not store transport layer address information:
adding a parameter, named as an access network entity transport layer Address (eNBTransport Address), to a parameter of a Handover Required message, for example, a transparent container sent by a source access network entity to a target access network entity, where the parameter is used for the source access network entity to transmit transport layer Address information used for establishing a connection to the target access network entity;
the core network element transmits the eNB Transport Address parameter to the target access network entity through the Handover Request message;
if the target access network entity receives the eNB Transport Address parameter, the target access network entity needs to establish connection with the source access network entity;
a target access network entity sends a Handover Request acknowledgement message (no change to the existing message) to a core network element;
a source access network entity receives a Handover Command message (no change to the existing message) sent by a core network element;
and the target access network entity establishes connection with the source access network entity.
In addition, the scheme can also adopt the source access network entity to inquire the transport layer address information of the target access network entity, and the premise is that the source access network entity maintains the transport layer address information of the target access network entity. The maintenance method can be as follows:
first, the source access network entity is manually pre-planned and set through an OAM interface.
And secondly, acquiring the corresponding relation through interface query between access network entities. For example, some access network entity or entities store the corresponding relationship, and other access network entities which do not previously store or store the old corresponding relationship can update the corresponding relationship through the interface.
Third, via an interface between the source access network entity and a network element of the core network (e.g., the S1 interface in LTE). When the access network entity is started or the information is changed, the core network element can tell the relation between the target access network entity identification corresponding to the source access network entity and the transport layer address information of the target access network entity.
In the embodiment of the invention, the intermediate network element acquires the transport layer address information of the target access network entity or the source access network entity according to the network element identifier, and the communication connection between the source access network entity and the target access network entity is realized according to the transport layer address information.
The embodiment of the invention also provides two methods for maintaining the information of the network element of the core network,
a first method, comprising:
the core network element inquires the transmission layer address information and the access network entity identification of the access network entity stored by other core network elements through an S10 interface between the core network element and other core network elements, the transmission layer address information and the access network entity identification have a corresponding relation, and the transmission layer address information is used for establishing the connection between the access network entities;
the network element of the core network stores the address information of the transmission layer of the access network entity corresponding to the identification of the access network entity.

a core network element receives transport layer address information sent by an access network entity, wherein the transport layer address information is used for establishing connection between the access network entities and is included in a connection establishment message or an access network entity configuration update message sent by the access network entity;
the network element of the core network stores the address information of the transmission layer of the access network entity.
Of course, the core network element may also maintain the transport layer address information by being manually planned in advance and set to the core network element through the OAM interface.
The method for maintaining the information of the core network element enables the core network element to dynamically acquire the transport layer address information so as to adapt to the communication establishment requirement between the source access network entity and the target access network entity.
