Description

Shared base station, service processing method and device of shared base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a shared base station, and a method and an apparatus for processing a service of the shared base station.

Background

At present, macro base station construction of a network basically tends to be saturated, and the requirements of network construction are basically concentrated in indoor coverage and hot spot blind-repairing and heat-supplementing stages. For indoor coverage, operators in the present stage basically only provide the traditional indoor division scheme in terms of indoor coverage, and the information source is provided by the operators. Along with the continuous promotion of indoor coverage capacity demand, each operator is constantly strengthening indoor coverage construction, especially the construction of novel room branch system. Traditional room distribution systems are gradually being abandoned by operators due to their untrustworthy and uncontrollable problems. Operators also want to explore new directions for indoor coverage co-construction sharing based on new indoor distribution systems. The specific requirements are as follows: supporting 4G (4th-Generation, fourth-Generation mobile communication technology) network services of three operators of China Mobile, China telecom and China Unicom through a set of base station equipment; the base station is respectively accessed to the core networks of three operators, and the operators do not construct special transmission networks; can be accessed to the superior network management of three operators respectively. For outdoor hot spot coverage, outdoor small station deployment is basically characterized in that an operator talks about a spot and installs the spot, and sharing and co-construction are basically difficult. In hot spots where blind and heat compensation is often needed, each operator has construction requirements.

The base station design of a single operator in the prior art is as follows: the base station needs to provide a single GE (Gigabit Ethernet) optical interface for the operator, so the base station needs to provide one SCTF (Switching control and transport hardware subsystem) board card, and there are 2 GE interfaces in total. Wherein the slot 1 SCTF board card is a master control board. The S1 interface selects an appropriate MME for the user to access and forward data according to the capacities of a PLMN (Public Land Mobile Network) and an MME (Mobility Management Entity) to which the user belongs. The S1Flex (load balancing function) feature implemented by the base station supports selection for the user MME, and the specific scheme is as shown in fig. 1: when the current version base station is started, if a board card is inserted into the slot 0, an OM (Operation management, Operation and maintenance) is considered as a dual-mode base station, the slot 1 main control board is a slave board, and in the characteristic, the slot 0 main control board only provides a hardware GE port and does not provide a software function. The load balancing function allows an eNB (Enhanced NodeB, Enhanced base station) to select a suitable MME for a UE (User Equipment), so that MMEs within the same Pool are balanced. The eNB has an NAS Node Selection Function (NNSF), the MME Capacity value of the MMEs in the same Pool is taken as a weight, an MME with relatively light load is selected, the quantity of access users of each MME is ensured to be in direct proportion to the MME Capacity as much as possible, and the balance of the MMEs in the same Pool is realized. When UE accesses, if PLMN and MMEC (Mobile Management Entity Code) carrying MME, eNB selects the MME for the UE; if only the PLMN is carried, the eNB selects an MME with lighter load from the MMEs meeting the PLMN. In order to calculate the MME load situation, the eNB needs to record the number of users currently accessed by each MME. When the S1 link status changes, the base station needs to consider whether there is an available MME by the cell operator, and if there is no available MME by the cell operator, the base station needs to deactivate the cell. Correspondingly, when the S1 link is restored, the base station needs to reactivate the cell.

The key point in the prior art is to guarantee a single S1 link, that is, the Base station belongs to a single network operator, a fixed geographical location, and maintenance, management, and optimization of the Base station are also performed by respective operators, as shown in fig. 2, where BBU (Building Base band Unit, indoor baseband processing Unit), RHuB (Radio Hub, Radio frequency Unit centralized controller), and PICO (small Base station) are main processing devices. With the scarcity of outdoor station positions and the increase of property maintenance cost, the cost of independently opening and maintaining outdoor base stations is higher and higher, and centralized management and maintenance cannot be realized; likewise, traditional indoor coverage is increasingly unacceptable due to regulatory and cost issues.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Fig. 3 shows an implementation schematic diagram of a shared base station provided in this embodiment, including: two SCTF main control boards; and the two SCTF main control boards are respectively inserted into the slot position 1 and the slot position 0 of the shared base station. Three operators (telecom Packet Core, unicom EPC and mobile EPC) are connected to a GE port of the SCTF main control board respectively.

Wherein, an IP-Radio Access Network (IP) port of each SCTF main control board is connected to a switch chip of the shared base station.

Specifically, there are two ways for implementing the shared base station, one is an external switch, and the other is two SCTF main control boards inserted according to this embodiment. It must be the SCTF master Control Board, but cannot use the SCTE (Switching Control and Transport Board Type) master Control Board, because only if the ip ran port of the SCTF master Control Board is connected to the Switching chip, the two master Control boards are equivalent to having a switch built in. The 1-slot main control board is an LTE main control board, the 0-slot main control board is only used for interface expansion, only BOOT and CORE versions need to be written in the 0-slot main control board Flash, the power is automatically loaded, an exchange chip is configured during CORE initialization, and then the exchange chip operates independently.

In the embodiment, a shared base station is formed by adding two SCTF main control boards in an original base station, and a corresponding MME can be determined according to different operator identifiers to perform service processing, so that frequency bands and formats of multiple operators are supported, different transmission networks do not need to be established for different operators, a service is provided for multiple operators through the shared base station at the same time, centralized management and maintenance can be performed, resources are saved, and a new operation mode can be brought to the operators.

Fig. 4 shows a flowchart of a service processing method for a shared base station provided in this embodiment, where the method includes:

s401, if a communication request of a terminal is received, determining an operator identifier and a base station identifier corresponding to the terminal according to the communication request.

Wherein the terminal is any terminal requesting to connect to the shared base station.

The communication request is a request for communication sent by the terminal to the sharing terminal.

The operator identification is the operator's ID, such as a telecommunications ID, a unicom ID, and a mobile ID.

The base station identification is the ID of the current shared base station.

S402, determining a target MME corresponding to the operator identifier according to the operator identifier.

In particular, for different operators, different MMEs supporting the operator need to be selected. For example, three operators of telecom, Unicom and Mobile have different MME respectively, and some MME only support telecom, not Unicom and Mobile; or, part of MME only supports connection and does not support telecommunication and movement.

The target MME is an MME supporting an operator corresponding to the current operator identity.

S403, receiving the request message sent by the MME according to the base station identifier, and processing the service of the terminal according to the request message.

Wherein, the request message is a request message sent by the MME to the shared base station.

For example, when performing indoor coverage, a BBU base station + multiple rhubs + multiple Pico RRUs (Radio Remote units) is needed, as shown in fig. 5, and frequency bands and systems of three operators are simultaneously supported. The frequency band of each operator can meet the requirements of the operator, for example, the mobile adopts an E frequency band 20M, the telecom and Unicom adopt an FDD frequency band, transmission network construction is not needed, a network management scheme of a shared base station can be directly accessed to northbound network management of each operator, the ability of the operator to communicate with property can be fully played, services can be provided for multiple operators simultaneously through the shared base station, resources are saved, and a new operation mode can be brought to the operator.

Further, on the basis of the above method embodiment, S401 specifically includes:

if a communication request of a terminal is received and a Radio Access Network Sharing (ran Sharing) switch is turned on, an operator identifier and a base station identifier corresponding to the terminal are determined according to the communication request and the Network planning S1 interface table.

S402 specifically includes:

and if only one MME corresponding to the operator identifier is found, determining the found MME as the target MME.

If the MME corresponding to at least two operator identifications is found, judging whether the load balancing function switch of S1 is turned on.

And if the S1 load balancing function switch is turned on, selecting the MME with the minimum capacity in the at least two MMEs as the target MME according to the load state of the MMEs.

Specifically, the configuration of adding ransharpening in HL (High Layer) is as follows:

1. if the ranringing switch is turned on, when an Access Point (AP) is established in the S1 link, the MME shall report the plmn id + enb bearer id to which the link belongs according to the operator information configured in the network planning S1 interface table, where the plmn id is the operator identifier and the enb bearer id is the base station identifier.

2. After the RRC (Radio Resource Control) connection is established, an MME supporting the PLMN needs to be selected for the user according to the selected PLMN-Identity reported by the UE. For the AP, if the ranringing switch is open, the MME is selected according to the following principle:

and screening MME according to PLMN reported by a user, and selecting the MME if only one MME is found.

If a plurality of MME are found, judging whether an S1Flex switch is turned on, if the S1Flex switch is turned on, selecting an MME with smaller capacity according to the load state of the MME; otherwise, according to the 'network planning S1 interface' table, the first available S1 link of the home PLMN is selected preferentially, and if not found, an MME is selected randomly.

The S1Flex indicates a load balancing function of the interface S1, which allows the eNB to select a suitable MME for the UE, so that the MMEs within the same Pool are balanced, thereby avoiding overload of a certain MME and enabling the user to obtain better experience.

Further, on the basis of the above method embodiment, S403 specifically includes:

receiving a context establishment request message, a direct-access stratum (NAS) request message or a handover request message sent by the MME according to the base station identifier, and determining a target operator of the shared base station service according to a handover restriction list carried in the context establishment request message, the direct-access stratum (NAS) request message or the handover request message.

And if the target operator is consistent with the operator identifier, allowing the terminal to switch.

And if the target operator is not consistent with the operator identifier, determining whether to allow the terminal to perform handover according to an EPLMN (Equivalent Public Land Mobile Network) of the terminal or a Public Land Mobile Network PLMN of a neighboring cell.

Specifically, the above process is not controlled by the RANSharing function switch. The context establishment request message, the direct transmission NAS request message and the switching request message which are sent to the base station by the MME may carry a Handover Restriction List, and the base station stores a switching Restriction List in the UE context, wherein the List comprises the EPLMNList. The user handover is also allowed if the serving PLMN of the target base station is different from the PLMN of the target cell but belongs to the EPLMN of the UE at the time of handover decision.

As shown in fig. 6, in the shared base station deployment, the determination of the PLMN of the handover target cell is added during the handover decision: if the current PLMN of the user is the same as the PLMN of the adjacent cell, a switching request is sent; if the two neighbor cell PLMNlists are different, checking the UE context, and if a Handover recovery List exists, the adjacent cell PLMN is in the UE Serving PLMN or the EPLMN List, and the adjacent cell PLMN is not in the forbidden PLMN PLMNlist, sending a switching request; and the target cell PLMN in the switching request sent by the source base station to the target base station or MME is the PLMN for switching the target cell. When the X2 is switched, the GUMMEI sent by the source base station to the target base station is the user GUMMEI (registered mme).

When selecting the inter-station handover, if the current PLMN of the user is different from the PLMN of the neighboring cell, it is determined that if the two PLMNs belong to the same MMEGroup, the X2 handover can be preferentially performed, otherwise, the S1 handover needs to be triggered. After receiving the X2 handover request, the target side uses the GUMMEI information of the user to query the MME table, and the GUMMEI information is ensured to be effective at the target side. The following two conditions are judged, and the handover is allowed as long as one is satisfied: whether the GUMMEI information in the message can be found in an MME table or not; or, the equivalent PLMN + GUMMEI (Globally Unique MME identity) partial parameter (GUMMEI GROUP ID + MMEC) information of the handover restriction list in the message can be found in the MME table.

If the target side receives the S1 HANDOVER request, the MME is necessarily in the MME table, so that the validity of the MME is not determined, and an ECGI (E-UTRAN Cell Global Identifier ) in a HANDOVER NOTIFY message sent to the MME carries the target Cell PLMN, where E-UTRAN (evolved UMTS Terrestrial Radio Access network) represents an evolved UMTS Terrestrial Radio Access network and UMTS (universal Mobile Telecommunications system) represents a universal Mobile communications system.

Further, on the basis of the above embodiment of the method, before S401, the method further includes:

s400, establishing a mapping relation between the operator gateway and the virtual local area network by adopting a mode of binding the double IP versions and the gateway.

Specifically, the existing VLAN (Virtual Local Area Network) table is a non-dual IP version, and only distinguishes VLAN IDs (ID numbers of Virtual Local Area networks) by classification, and is divided into four types, i.e., an S1 signaling, an S1 user, an X2 signaling, and an X2 user, but has no operator information, and cannot distinguish between the two types; if the dual-IP version can support multiple operators VLAN, the dual-IP version VLAN id is bound to the gateway, and the gateways of different operators are different, the dual-IP version VLAN id can be distinguished by the gateway, that is, the following mapping relationship is implemented:

for the S1 link table, the S1 link also needs to distinguish different operators, so as to facilitate subsequent service differentiation.

Further, on the basis of the foregoing method embodiment, S402 specifically includes:

Specifically, the shared base station provided in this embodiment needs to maintain different differentiated transmission service tables or add information for differentiating operators to an original table, so as to configure transmission service levels in a differentiated manner according to requirements of different operators, and therefore, when determining the target MME, the target MME corresponding to the operator identifier needs to be determined according to the operator identifier and a preset operator service level.

In addition, the shared base station provided in this embodiment needs to support multiple channels, needs to distinguish settings of different operators corresponding to different channels in a configuration file, and the OM distinguishes when establishing a Channel and establishing a signaling FLOW, and needs to inform the HL, so as to distinguish when establishing a service FLOW.

It should be noted that if the board card is inserted into the slot 0, the OM is considered as a dual-mode base station, the slot 1 main control board is a slave board, and in this characteristic, the slot 0 main control board only provides a hardware GE port and does not provide a software function, so that in this characteristic, the judgment condition that the slot 1 main control board is the slave board when the slot 0 board card hardware is in place in the master/slave decision should be skipped, and the slot 1 main control board is directly set as the master board.

This embodiment is through the main control board external interface extension, realizes that different channels correspond different operator's setting and RANSharing configuration, the judgement to switching target cell PLMN during switching judgement: the determination of different operators is bound with the gateway through a VLANID table, and if the gateways of different operators are different, the different operators can be distinguished through the gateways; the confirmation of different S1 addresses is realized by that when the S1 link is established, the AP reports the PLMNID + ENBGLOABID of the link attribution to the MME according to the operator information configured in the network planning S1 interface table; and when in switching judgment, the confirmation of the switching target cell PLMN is added, and the PLMN judgment is carried out when in switching.

For example, as shown in fig. 7, from the actual situation of network operation, in combination with the existing base station transmission and coverage scheme, aiming at the new coverage requirement and the facing requirements for site selection and operation and maintenance of the existing network, the existing base station is modified on the basis of the existing base station, the hardware change is required to be small, and through the software change, 1 base station, multiple frequency band coverage, multiple operators used simultaneously, unified operation and maintenance management are realized, so that a new solution for indoor coverage and hot spot coverage is realized, and the optimal selection is provided without increasing manpower and material resources.
