Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a related apparatus for saving processing resources in a network element.
Background
As defined by the third Generation Partnership Project (3rd Generation Partnership Project,3GPP), inter-network element communication is currently based on two bearer technologies: internet Protocol (IP) and Asynchronous Transfer Mode (ATM).
Currently, for User data bearer under IP transmission, the User data bearer is based on a User Datagram Protocol (UDP). For each data ground bearer of each user, one UDP port number resource is consumed at each end. In the standard protocol, the occupancy of the UDP port number is a fixed 2 bytes, that is, the maximum number of values is 65535, and the standard protocol also includes a known UDP port number. Each data ground bearer requires that the quadruple (home IP address, home UDP port number, opposite IP address and opposite UDP port number) must be unique. Under the premise of limited UDP port numbers, in order to support more users, IP addresses must be added to ensure the unique identification of data ground bearer. Thus, the following problems are brought about:
1. the UDP port number resources required by the calculation of the supported user number are complex, and even certain consistency with actual requirements cannot be ensured;
2. when planning to use, the complexity of networking and realization needs to be introduced by avoiding the known UDP port number;
3. when the IP resource is limited, the number of supported users cannot be expanded;
4. the receiving equipment positions the processing example according to the four-tuple (the home IP address, the home UDP port number, the opposite IP address and the opposite UDP port number), the algorithm is complex, and the performance is reduced;
5. under the condition that transmission resources are limited, bandwidth resource overhead is reduced by adopting UDP multiplexing, but due to the change of IP addresses, the actual UDP multiplexing rate is lower.
Similarly, currently, the user data bearer under ATM transmission is based on ATM Adaptation Layer (AAL 2) protocol, and for each data ground bearer of each user, a Channel Identifier (CID) of AAL2 on a Permanent Virtual Circuit (PVC) needs to be consumed. The occupation of the CID is a fixed 1 byte, that is, the maximum number 255 is taken, and the protocol reservation CID is also included. Each data ground bearer requires that the binary group (PVCID, CID) is unique. In order to support more users, the PVC must be added to ensure unique identification of the data ground bearer on the premise that the CID is limited. Thus, the following problems are brought about:
1. the CID resources required by the calculation combined with the supported user number are complex, and even certain consistency with actual requirements cannot be ensured;
2. when planning to use, CID reserved by a protocol needs to be avoided, and networking and implementation complexity is introduced;
3. under the condition that PVC is limited, the number of supported users cannot be expanded;
4. the receiving equipment positions and processes the example according to the binary group (PVCID, CID), the algorithm is complex, and the performance is reduced;
and 5, the number of the PVC is increased, and the complexity of PVC bandwidth configuration, planning and maintenance is increased.

Wherein, the transmission identifier comprises an IP address and a UDP port number under IP transmission and comprises a PVCID and a CID under ATM transmission.
Fig. 3 is a schematic block diagram of a second method for saving processing resources in a network element according to an embodiment of the present invention, as shown in fig. 3, including:
step 301: during the communication period between the sending network element and the receiving network element, the sending network element and the receiving network element determine to adopt the conventional message or the extension message for communication through negotiation.

Wherein the transmission identifier comprises an IP address and a UDP port number under IP transmission and comprises a PVCID and a CID under ATM transmission.
The invention can not only save the processing resources in the network elements, but also save the transmission resources between the network elements. The requirement for resources of IP addresses and UDP port numbers is reduced under IP transmission, and the requirement for resources of PVC and CID numbers is reduced under ATM transmission. Therefore, the invention provides a maintenance mode of data ground bearing, which comprises the following steps: in IP transmission, the index identifier (i.e. processing entity identifier) of the processing Data entity (i.e. processing entity) in the receiving device (i.e. receiving network element) is carried by extending the user Data Unit (SDU) of UDP or using fields not used in IP and UDP headers. In ATM transmission, the SDU via the extension AAL2 carries the index identity of the processing data entity within the receiving device.
Fig. 5 is a schematic block diagram of a third method for saving processing resources in a network element according to an embodiment of the present invention, as shown in fig. 5, the steps include:
step 501: the data format is negotiated between the communication devices through the existing signaling interaction process, and the negotiation of the alternative data format can also be configured at the two ends of the communication devices.
The present embodiment divides the communication device into a data sending device (i.e., a sending network element) and a data receiving device (i.e., a receiving network element).
Step 502: the communication equipment interacts SDU extension information carried by data of each user through the existing signaling interaction flow.
Wherein, the SDU extension information contains the processing entity mark of the data receiving device, so that the data receiving device can directly deliver the message according to the processing entity mark.

And (3) packaging the module 63: and is configured to encapsulate data according to a negotiation result during transmission, that is, encapsulate a data packet according to a negotiated data packet format (i.e., a packet encapsulation format).
The decapsulation module 64 is configured to parse the data packet according to the negotiation result, and deliver the parsed data packet to the processing entity according to the distributed distribution identifier, that is, parse the data packet, and distribute the parsed data packet to the processing entity according to the processing entity identifier.
The apparatus provided in fig. 2, 4 and 6 is suitable for wireless access controller products in the wireless communication field, and is also suitable for other data communication products using access to the Internet. The modules in the device can be deployed in a centralized manner or in a separated manner, and the modules can be combined or further split into a plurality of small modules.
Those skilled in the art will appreciate that the modules in the example apparatus may be distributed in the example apparatus as described in the example embodiments, and may be correspondingly modified in one or more apparatuses other than the example embodiments.
For IP transmission, in the prior art, for each data ground bearer of a user, a quadruple (a home IP address, a home UDP port number, an opposite IP address, and an opposite UDP port number) is required to be unique, so that a receiving network element can be positioned to a processing entity by using the unique quadruple, and as a result, the more data ground bearer paths, the greater the consumption of the UDP port number and the IP address. The invention adds the processing entity identification of the receiving network element in the extended message, so that the receiving network element can directly position the corresponding processing entity through the processing entity identification of the receiving network element after receiving the extended message, thereby reducing the requirements on UDP port numbers and IP addresses.
Likewise, for ATM transmission, the two-tuple (PVCID, CID) is required to be unique for each data terrestrial bearer of each user in the prior art, so that the receiving device can be located to the processing entity using the unique two-tuple, and it can be seen that the greater the number of data terrestrial bearer paths, the greater the consumption of PVC and CID. The invention adds the processing entity identification of the receiving network element in the extended packet, so that the receiving network element can directly position the corresponding processing entity through the processing entity identification of the receiving network element after receiving the extended packet, thereby reducing the requirements on CID and PVC.
Fig. 7 is a schematic diagram of interaction between network elements of an Iub port under IP transmission according to an embodiment of the present invention, and as shown in fig. 7, transmission resources between network elements are saved by the Iub port under IP transmission, where the steps include:
step 701: a Radio Network Controller (RNC) informs a base station NodeB of a data encapsulation format (i.e., a packet encapsulation format) that can be received by the RNC through standard signaling.
For example, the audit request at the Iub port carries a data encapsulation format cell, which indicates that the data encapsulation format receivable by the RNC is to insert SDU extension information into the SDU header of UDP, and the data encapsulation format is shown in fig. 9.
Step 702: and the NodeB confirms whether the data packaging format indicated by the RNC is supported or not through standard signaling, and informs the RNC of the receivable data packaging format.
For example, the data encapsulation format of the RNC is supported in the audit response of the Iub port, and the data encapsulation format receivable by the NodeB is indicated to be a normal UDP packet format, as shown in fig. 10.
Step 703: in the service process, the RNC transmits the local terminal transmission identifier and the service entity identifier of the data ground bearer link to the NodeB through standard signaling.
For example, the radio link establishment request at the Iub port carries encapsulation information at the RNC side, where the encapsulation information at the RNC side includes a transmission identifier, i.e., an IP address and a UDP port number, and an SDU extension field of UDP, where the SDU extension information is in the SDU extension field.
Step 704: and the NodeB transmits the local terminal transmission identifier of the data ground bearing link to the RNC through standard signaling.
For example, the radio link establishment response at the Iub port carries the encapsulation information at the NodeB side, the IP address of the encapsulation information at the NodeB side, and the UDP port number.
Step 705: when RNC sends data to NodeB, the data message is packaged according to the data packaging format indicated by NodeB and sent to NodeB, at this time, the data message packaged and sent to NodeB by RNC is a conventional message.
For example, the RNC encapsulates a normal UDP packet according to the information obtained in step 12 and step 14 and sends the packet to the NodeB.
Step 706: and the NodeB receives the data message sent by the RNC, analyzes the data message and distributes the data message to a corresponding processing entity according to the IP address and the UDP port number.
For example, the NodeB receives the UDP packet, and directly locates the processed board and the user plane processing instance on the board according to the UDP port number at the NodeB side.
Step 707: when NodeB sends data to RNC, the data message is packaged according to the data packaging format indicated by RNC and sent to RNC, at this time, the data message packaged by NodeB and sent to RNC is an extended message.
For example, the NodeB encapsulates the extended UDP packet according to the information obtained in step 11 and step 13, and inserts the SDU extension information of the RNC side after the UDP header.
Step 708: and the RNC receives the data message sent by the NodeB, analyzes the data and distributes the data to a corresponding processing entity.
For example, the RNC receives the extended UDP packet, determines the current packet encapsulation format according to the UDP port number on the RNC side, and extracts the SDU extension information from the back of the UDP header, where the SDU extension information includes the identifier of the processing entity in the RNC device and is directly delivered to the processing entity.
The embodiment can effectively reduce the requirement of the RNC for the IP address docking of the Iub port, and carry the identifier (namely the service entity identifier) suitable for the rapid distribution in the RNC according to the self-defined SDU extension information, thereby achieving the purpose of rapidly distributing the Iub port data and reducing the time delay introduced by data processing in the RNC.
Fig. 8 is a schematic diagram of interaction between network elements of an ATM transmission Iub port according to an embodiment of the present invention, and as shown in fig. 8, the Iub port saves transmission resources between network elements in ATM transmission, and the steps include:
step 801: the RNC informs NodeB of the data encapsulation format which can be received by the RNC through standard signaling.
For example, the audit request at the Iub port carries a data encapsulation format cell, which indicates that the RNC can receive the data encapsulation format, and the SDU extension information is inserted into the SDU header of the AAL2 protocol, as shown in fig. 11.
Step 802: and the NodeB confirms whether the data packaging format indicated by the RNC is supported or not through standard signaling, and informs the RNC that the NodeB can receive the data packaging format.
For example, data encapsulation format of RNC is supported in audit response of Iub port, and data encapsulation format receivable by NodeB is indicated, and as shown in fig. 11, SDU extension information may be inserted in the SDU header of AAL2 protocol.
Step 803: in the service process, the RNC transmits the local terminal transmission identifier of the data ground bearing link and the service entity identifier of the RNC to the NodeB through standard signaling.
For example, the radio link establishment request of the Iub port carries RNC-side encapsulation information, where the RNC-side encapsulation information includes a local transport identifier, that is, a CID of AAL2, and an SDU extension field of AAL2, and the SDU extension field of AAL2 is RNC-side SDU extension information.
Step 804: and the NodeB transmits the local terminal transmission identifier of the data ground bearing link and the service entity identifier of the NodeB to the RNC through standard signaling.
For example, the radio link setup response of the Iub port carries the transmission identifier of the NodeB side, i.e., the CID of AAL2, and the SDU extension field of AAL2, where the SDU extension field of AAL2 is SDU extension information of the NodeB side.
Step 805: when the RNC sends data to the NodeB, the data message is packaged according to the data packaging format indicated by the NodeB and sent to the NodeB, and the data message packaged and sent in the step is an expanded message.
Step 806: and the NodeB receives the data message sent by the RNC, analyzes the data message and distributes the data message to a corresponding processing entity according to the SDU extension field content in the data message.
Step 807: when the NodeB sends data to the RNC, the NodeB encapsulates the data message according to the data encapsulation format indicated by the RNC and sends the data message to the RNC, wherein the data message encapsulated and sent in the step is an extension message.
Step 808: and the RNC receives the data message sent by the NodeB, analyzes the data message and distributes the SDU extension field content in the data message to a corresponding processing entity.
The embodiment effectively reduces the requirement of the Iub port for PVC docking, and achieves the purpose of rapidly distributing the Iub port data by carrying the identifier (namely the service entity identifier) suitable for rapid distribution in the RNC or NodeB according to the user-defined SDU extension information.
In this embodiment, because the need for the CID is reduced, theoretically, only one CID is needed on one PVC to transmit Iub port data, and signaling traffic for CID keep-alive between network elements is indirectly reduced.
From the above description, it is clear for those skilled in the art that the present invention can be implemented by software plus necessary general hardware platform, and also can be implemented by hardware. The technical scheme of the invention makes a contribution to the prior art and can be embodied in the form of software products.
